Description

Technical Field

[0001] This application belongs to the field of material packaging frame technology, specifically relating to a material frame fixing device and a material packaging frame palletizing and warehousing production line. Background Technology

[0002] Some flexible bales, such as those for holding tobacco leaves, are made by packaging and transporting raw tobacco leaves (i.e., bales) in burlap sacks after the tobacco leaves have been harvested and cured. After being transported to a designated location by truck, the bales are stacked into standard frames with mesh baffles on two sides and openings on the other two sides using automated equipment, arranged in pairs of four bales per layer, four layers per frame. When forks are used to lift the four bales, a cylinder pressure plate presses down on the bales in the height direction to secure them, and then they are transferred to the top of the frame. Because the width of the four bales is not controlled or limited, and the width of the bales tends to increase when compressed in the height direction, if the total width of the four bales exceeds the inner width of the standard frame, the bales will get stuck at the frame opening and cannot be stacked. Furthermore, standard tobacco baskets are subjected to the weight of the tobacco bags for a long time, causing the width of the U-shaped opening to decrease, increasing the risk that the tobacco bags cannot be placed into the basket for stacking. Summary of the Invention

[0003] The purpose of this application is to provide a material frame fixing device and a material package frame palletizing and warehousing production line to solve the technical problem that the material package is stuck at the opening of the material frame and cannot enter the material frame for palletizing.

[0004] To achieve the above objectives, this application provides a material frame fixing device for fixing an empty material frame. The empty material frame includes a frame body for stacking material bags, and the frame body has a U-shaped opening in the width direction for the material bags to enter. The material frame fixing device includes:

[0005] Support frame, used to support the material frame body;

[0006] A locking mechanism, the locking mechanism including a spreading component, the spreading component being used to apply a opposing force to the top end of the material frame body along the width direction, such that the width of the material frame body is greater than the width of the material bag inside the material frame body.

[0007] In some embodiments, the material frame body includes a support mesh plate and mesh baffles disposed on both sides of the support mesh plate. The two mesh baffles are arranged at intervals along the width direction of the support mesh plate. Each mesh baffle can be folded and connected to the support mesh plate. The spreading component is used to apply opposing forces to the tops of the two mesh baffles.

[0008] In some embodiments, the support frame includes two support components spaced apart along the length direction, each support component including two second support members spaced apart along the width direction and a support rod connecting the two second support members.

[0009] In some embodiments, the second support member includes a first support column and a second support column connected by a connecting rod. The first support column in each of the second support members is connected by the support rod. The spreading assembly is disposed on the second support column and is located near the top. Two spreading assemblies arranged on the same side in the width direction apply opposite forces to the top of the corresponding mesh baffle.

[0010] In some embodiments, the spreading assembly includes a second drive member and a drive block connected to the second drive member, the second drive member being used to drive the drive block to rotate to a position on the opposite side of the two mesh baffles, and to drive the drive block to move linearly to apply a vertical force to the mesh baffles.

[0011] In some embodiments, the bottom of the material frame body is provided with a plurality of first support members, the number of which is multiple and located at the bottom of the support mesh plate, and the plurality of first support members are symmetrically located around the support mesh plate.

[0012] In some embodiments, the locking mechanism further includes a clamping assembly for applying a clamping force to the first support member to clamp the first support member and the support frame. The clamping assembly is disposed on the first support column and includes a clamping part for applying a clamping force to the first support member and a first driving member for driving the clamping part to rotate and move linearly.

[0013] In some embodiments, the first support column is provided with a positioning element, and the bottom of the first support element has a positioning groove. The shape of the positioning element is adapted to the shape of the positioning groove and is locked in place.

[0014] In some embodiments, both the first drive member and the second drive member are vertical rotary cylinders.

[0015] The second aspect of this application provides a material packaging frame palletizing and warehousing production line, including the material frame fixing device as described above.

[0016] Through the above technical solution, the material frame fixing device of this application includes a support frame and a locking mechanism; the support frame is used to support the material frame body. The locking mechanism includes a spreading component. When packing and stacking, the material frame body is placed on the support frame, and the spreading component applies opposing spreading forces to the top part of the material frame body along the width direction, so that the two ends of the material frame body along the width direction are spread outward, thereby making the width of the material frame body greater than the width of the material bag inside the material frame body. This eliminates the risk that the width of the material frame will decrease due to the long-term weight of the material bag, and thus solves the technical problem that the material bag is stuck at the opening of the material frame and cannot enter the material frame for stacking.

[0026] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0027] The following description, with reference to the accompanying drawings, describes the material frame fixing device 500 and the material packing frame stacking and warehousing production line according to this application. The material frame fixing device 500 can be used to fix empty material frames 600, which can be used to stack material bales 700. The material bales 700 can be raw tobacco bales containing tobacco leaves, or bales containing flexible materials, such as sawdust or straw. For ease of understanding, the following description uses a tobacco bale containing tobacco leaves as an example.

[0028] When packing and stacking tobacco bales, the raw tobacco leaves are compressed together and placed into burlap sacks to form the bales, giving them a certain degree of flexibility. When the gripping device 100 grabs the top surface of the tobacco bale and hooks it upwards, the weight of the tobacco leaves causes the bale to lengthen in the height direction and shrink in the width direction. In this state, the gripping device 100 transports the tobacco bales to the empty tobacco frame and stacks them according to a rule of four tobacco bales per layer, for a total of four layers. The empty tobacco frame has a U-shaped structure with mesh baffles 61 on two sides and openings on the other two sides. The mesh baffles 61 on both sides can be folded and opened. The width of the U-shaped opening of the empty tobacco frame is fixed, being the sum of the widths of two tobacco bales. However, due to the long-term influence of the weight of the tobacco bales, the width of the U-shaped opening tends to decrease.

[0029] In view of this, such as Figures 1 to 3 As shown, this application provides a material frame fixing device 500 for fixing an empty material frame 600. The empty material frame 600 includes a material frame body for stacking material bags 700. The width direction of the material frame body has a U-shaped opening for the material bags 700 to enter. The material frame fixing device 500 includes a support frame 50 and a locking mechanism. The support frame 50 is used to support the material frame body. The locking mechanism includes a spreading component 52. The spreading component 52 is used to apply a force opposite to the top of the material frame body in the width direction, so that the width of the material frame body is greater than the width of the material bags 700 inside the material frame body.

[0030] In this embodiment, during packing and stacking, the rail-guided RGV mother-daughter trolley places the material frame body on the support frame 50. The spreading component 52 applies opposing spreading forces to the top part of the material frame body along the width direction, so that the two ends of the material frame body along the width direction are spread outward, thereby making the width of the material frame body greater than the width of the material bag 700 inside the material frame body. When the width of the material frame body is greater than the width of the material bag 700 after stacking, the risk of the width of the material frame becoming smaller due to the long-term gravity of the material bag 700 can be eliminated, thereby solving the technical problem that the material bag 700 is stuck at the opening of the material frame and cannot enter the material frame for stacking.

[0031] In some implementations, such as Figure 3 As shown, the material frame body includes a supporting mesh plate 60 and mesh baffles 61 disposed on both sides of the supporting mesh plate 60. The two mesh baffles 61 are arranged at intervals along the width direction of the supporting mesh plate 60, thus forming an open U-shaped structure in the width direction. Figure 4 and Figure 5 As shown, each mesh baffle 61 and the supporting mesh plate 60 can be folded and connected. The spreading component 52 is used to apply opposing forces to the tops of the two mesh baffles 61.

[0032] In this embodiment, when the material frame body is empty, the mesh baffles 61 on both sides are folded, and the cigarette frames are stacked to save floor space. When the material bags 700 are framed, the mesh baffles 61 on both sides open and support, constraining the stacked raw cigarette bags along the width direction, preventing the four-layer stack of raw cigarette bags from collapsing, and placing all the QR codes 800 on the cigarette bags facing outwards for easy scanning of their information. In addition, the mesh baffles 61 on both sides can also provide support, allowing multiple full cigarette frames to be stacked for storage, saving warehouse storage space. Before the cigarette bags are framed, after the mesh baffles 61 on both sides are opened, the spreading component 52 applies opposing forces to the tops of the two mesh baffles 61, causing the tops of the two mesh baffles 61 to be pried outwards respectively, ensuring that the width of the U-shaped opening of the cigarette frame is greater than the sum of the widths of the two cigarette bags, thereby eliminating the risk that the width of the U-shaped opening of the cigarette frame will decrease due to the long-term gravity of the raw cigarette bags.

[0033] In some embodiments, the locking mechanism further includes a clamping component 51, which applies a clamping force to the first support member 62 to clamp the first support member 62 and the support frame 50. During packing and stacking, the clamping component 51 applies a downward clamping force to the first support member 62, thereby clamping the first support member 62 and the support frame 50 under the material frame body to prevent the empty material frame 600 from changing position during the packing process. Multiple first support members 62 are provided at the bottom of the material frame body. These multiple first support members 62 are located at the bottom of the support mesh plate 60 and are symmetrically located around the support mesh plate 60. Preferably, there are four first support members 62, located at the four bottom corners of the support mesh plate 60 and symmetrically distributed, which makes the force on the support mesh plate 60 more uniform. When the clamping component 51 applies a clamping force to the first support member 62, it ensures a more stable connection between the support mesh plate 60 and the support frame 50.

[0034] In some embodiments, the support frame 50 is provided with a positioning member 501 that is limited and cooperates with the first support member 62. The bottom of the first support member 62 has a positioning groove, and the shape of the positioning member 501 is adapted to the shape of the positioning groove and is limited and engaged.

[0035] The positioning groove is a semi-circular groove, and the positioning element 501 is a semi-circular positioning support ball. When the empty material frame 600 is placed on the support frame 50, the pressing component 51 presses down on the first support element 62, thereby causing the positioning groove on the first support element 62 to move toward the positioning element 501. Under the action of the downward pressure, the positioning groove and the positioning element 501 are engaged, thereby realizing the limiting engagement between the first support element 62 and the support frame 50.

[0036] In some embodiments, the support frame 50 includes two support components spaced apart along its length. Each support component includes two second support members spaced apart along its width and a support rod 504 connecting the two second support members. During fixing, the four corners of the empty material frame 600 are connected to the four second support members, thereby securing the empty material frame 600 from all sides. Since the empty material frame 600 has a U-shaped opening in its width direction, the two second support members arranged along the width direction are connected by the support rod 504 to ensure stability in the width direction and provide stable support to both sides of the empty material frame 600 in the width direction, allowing the material bag 700 to be smoothly pushed through the U-shaped opening.

[0037] In some embodiments, the second support member includes a first support column 502 and a second support column 503 connected by a connecting rod. The first support column 502 in each second support member is connected by a support rod 504. A positioning member 501 is disposed on the first support column 502 and adapted to a positioning groove. A clamping assembly 51 is disposed on the first support column 502 and includes a clamping part 512 that applies a clamping force to the first support member 62 and a first driving member 511 for driving the clamping part 512 to rotate and move linearly.

[0038] The height of the first support column 502 is less than the height of the second support column 503. The first support column 502 supports the first support member 62, and the second support column 503 is located on the outer periphery of the entire empty material frame 600. When the first support member 62 is pressed, the first driving member 511 drives the pressing part 512 to rotate above the first support member 62 and drives the pressing part 512 to move downward to apply a downward pressing force to the first support member 62, so that the first support member 62 and the first support column 502 are locked together by their locking structure.

[0039] In some embodiments, the spreading component 52 is disposed on the second support column 503 and near the top, and the two spreading components 52 arranged on the same side in the width direction apply opposite forces to the top of the corresponding mesh baffle 61.

[0040] In this embodiment, the height of the second support column 503 is greater than the height of the mesh baffle 61. The second support column 503 and the side of the mesh baffle 61 are arranged parallel to each other at intervals. The spreading component 52 is located near the top of the second support column 503. When the two spreading components 52 apply opposite forces to the adjacent mesh baffles 61, the top of the mesh baffles 61 is pried open outwards, so that the width of the U-shaped opening between the two mesh baffles 61 is greater than the width of the material bag 700.

[0041] In some embodiments, the spreading assembly 52 includes a second drive member 521 and a drive block 522 connected to the second drive member 521. The second drive member 521 drives the drive block 522 to rotate to a position where the two mesh baffles 61 face each other, and drives the drive block 522 to move linearly to apply a vertical force to the mesh baffles 61. When applying a spreading force to the mesh baffles 61, the second drive member 521 drives the drive block 522 to rotate to the inner side of the mesh baffles 61 and applies a vertical force to the drive block 522. The two driving forces for the same mesh baffle 61 are in the same direction, and the forces acting on the two mesh baffles 61 are opposite, thereby driving the two mesh baffles 61 to be spread outward.

[0042] In some embodiments, both the first drive member 511 and the second drive member 521 are vertical rotary cylinders. The vertical rotary cylinder is a special type of cylinder commonly used in the prior art, integrating rotation and linear motion. It can achieve vertical rotation (typically 90° or 180°) while also possessing linear motion capabilities. For example, one prior art vertical rotary cylinder can employ a rack and pinion structure, primarily where the cylinder piston drives the rack to move linearly, and the meshing of the gears achieves rotation. Since this vertical rotary cylinder is a common structure in the prior art, it will not be described in detail here.

[0043] Specifically, in application, when the empty material frame 600 is placed on the surface of the support frame 50, the semi-circular positioning grooves at the bottom of the four first support members 62 of the empty material frame 600 cooperate with the four semi-circular positioning members 501 on the support frame 50, so that the empty material frame 600 is precisely positioned on the support frame 50. Then, the four vertical rotating cylinders on the support frame 50 clamp and fix the four first support members 62 of the empty material frame 600 by rotating and driving downwards, preventing the robot from knocking the empty material frame 600 askew or overturning it during stacking. Then, the four longitudinal vertical rotating cylinders at the top rotate and drive outwards to pry open the four corners of the upper end of the mesh baffle 61 of the empty material frame 600 outwards in the width direction.

Since this material packaging frame palletizing and warehousing production line employs all embodiments of the aforementioned material frame fixing device 500, it possesses all the beneficial effects brought about by the aforementioned material frame fixing device 500, which will not be elaborated upon here.
