[0049] The following further describes the present utility model in conjunction with the Figures 1 - 9 accompanying drawings.

[0050] Embodiment 1

[0051] In view of the technical problems existing in the background art, the present utility model provides an automatic bundling device for bagged koji.

[0052] In the specific technical solution, referring to Figure 1 and Figure 2 , the automatic bundling device includes a chain conveyor 1, a robot 2, a vertical bundling machine 3, and a vertical bundling machine 4. The chain conveyor 1 is used to support and convey the koji block stack 9. The koji block stack 9 includes a tray 901 and bagged koji 902 placed on the tray 901. A horizontal bundling station 101 and a vertical bundling station 102 are provided on the chain conveyor 1; the robot 2 is arranged beside the horizontal bundling station 101 to clamp the tray 901 and the bagged koji 902; the vertical bundling machine 3 is arranged at the horizontal bundling station 101 to horizontally bundle each layer of koji blocks on the tray 901; the vertical bundling machine 4 is arranged at the vertical bundling station 102 to vertically bundle the bagged koji 902 and the tray 901 together. The vertical bundling machine, the vertical bundling machine, the robot, and the chain conveyor are existing technical equipment and are borrowed by the present utility model, and their working principles and structures will not be described in detail here. The vertical bundling machine and the vertical bundling machine can adopt the MH-105 series bundling machines produced by Hangzhou Yongchuang Intelligent Equipment Co., Ltd., and the robot can adopt the IRB6700-150 / 3.2 series robots produced by ABB.

[0053] Working principle: First, the robot 2 grabs the empty tray 901 to the horizontal bundling station 101 of the chain conveyor 1, and then starts to grab the bagged koji 902 onto the tray 901. After stacking one layer of bagged koji, the vertical bundling machine 3 performs horizontal bundling on the koji blocks of this layer. The vertical bundling machine 3 performs horizontal bundling on the koji blocks layer by layer until the stacking of koji blocks is completed. After the horizontal bundling of the koji block stack is completed, the chain conveyor 1 synchronously transports the tray 901 and the bagged koji 902 thereon to the vertical bundling station 102, and then the vertical bundling machine 4 bundles the koji blocks vertically. During bundling, the tying tape passes through the jack of the tray 901 to bundle the koji blocks and the tray 901 together. After bundling, the bundled koji block stack can be transported by a forklift.

[0054] From the above structure and working principle, it can be seen that the utility model not only performs layer-by-layer horizontal bundling on the koji block stack, but also vertically bundles the koji blocks and the tray together to form a koji block stack, greatly enhancing the bundling stability of the koji block stack. At the same time, it is also convenient for the transportation and transfer of the koji block stack, improving the transfer efficiency of the koji block stack.

[0055] If the bagged koji 902 stacked on the tray 901 are all arranged in the same direction, it will lead to poor stability of the koji block stack and a risk of tipping. Therefore, the utility model makes the following further improvements: Referring to Figure 1 and Figure 2 , in this embodiment, the two chain conveyors are divided into two, specifically: The chain conveyor 1 includes a first chain conveyor 103 and an adjacent second chain conveyor 104. The first chain conveyor 103 is arranged at the horizontal bundling station 101, and the second chain conveyor 104 is arranged at the vertical bundling station 102.

[0056] Among them, it also includes a first power assembly 5 for driving the first chain conveyor 103 to rotate horizontally. The rotatable first chain conveyor 103 is used to turn the tray 901 and the koji blocks thereon to achieve staggered stacking of adjacent layers of koji blocks vertically, and the koji blocks between adjacent layers vertically are perpendicular to each other.

[0057] Specifically, referring to Figure 3 and Figure 4 The first power assembly 5 includes a base 501. A reduction motor 502 is arranged on the base 501. A gear 503 is arranged at the output end of the reduction motor 502. A slewing bearing 504 is arranged at the bottom of the first chain conveyor 103. The gear 503 is in meshing connection with the slewing bearing 504.

[0058] Working principle: The first chain conveyor 103 is set to be rotatable so that the robot can alternately place the curved blocks of adjacent layers at 290°. For example, after the robot 2 places a layer of baguette 902 on the tray 901, the first power component 5 drives the first chain conveyor 103 to rotate 90°. Then the robot 2 places the second layer of baguette 902, and so on. Every time the robot 2 places a layer of baguette, it needs to rotate 90°. Such a placement method will make the baguettes 902 between adjacent upper and lower layers be arranged in a 90° staggered manner.

[0059] As can be seen from the above structure and working principle, after the robot of the present utility model places each layer of baguette on the tray, the first chain conveyor rotates 90°, so that the curved blocks arranged between adjacent layers on the tray are staggered by 90°, improving the stability of the stacking of the curved blocks and the stability of the stack of curved blocks.

[0060] To prevent the tray 901 from moving on the first chain conveyor 103 and causing misalignment when the robot places the curved blocks, the following further improvements are made in this embodiment: Refer to Figure 3 This embodiment also provides a fixing component 6. The fixing component 6 is arranged on the first chain conveyor 103, and the fixing component 6 can fix the tray 901 on the first chain conveyor 103.

[0061] Specifically, the fixing component 6 includes a stop bar 601 arranged on one side of the first chain conveyor 103. A push plate 602 and a second power component 603 for driving the push plate 602 to move towards the stop bar 601 are arranged on the opposite side of the first chain conveyor 103 where the stop bar 601 is located. The fixed end of the second power component 603 is connected to the first chain conveyor 103, and the movable end of the second power component 603 is connected to the push plate 602. The second power component 603 uses a cylinder, which has a simple structure and is convenient to arrange.

[0062] Working principle: After the robot 2 grabs the tray 901 onto the first chain conveyor 103, the second power component 603 extends, driving the push plate 602 to move towards the stop bar 601, and then fixing the tray 901 between the stop bar 601 and the push plate 602. It can be seen that the present utility model can fix the tray on the first chain conveyor, prevent the tray from moving on the first chain conveyor, and improve the accuracy of the robot placing the baguette and the stability of the stacking of the baguette.

[0063] Embodiment 2

[0064] There are gaps between the baguettes picked up by the robot and placed on the tray. If the gaps are not eliminated, the bundled curved blocks are still relatively loose and have poor stability. Therefore, on the basis of Embodiment 1, the following further improvements are made in this embodiment: Refer to Figure 5 and Figure 6, this embodiment further includes a shaping component 7, which is used to limit and shape the curved blocks of each layer; the vertical strapping machine 3 includes a vertical frame 301, on which a strapping frame 302 is provided, and the shaping component 7 is arranged on opposite sides of the strapping frame 302, and the number of the shaping components 7 matches the number of rows of the curved blocks.

[0065] Specifically, referring to Figure 7 and Figure 8 , the shaping component 7 includes a third power component 701, the fixed end of the third power component 701 is connected to the strapping frame 302, the movable end of the third power component 701 is provided with a shaping bracket 702, a resisting rod 703 is arranged on the shaping bracket 702, a resisting plate 704 is arranged at the end of the resisting rod 703, and there is a certain distance between the upper and lower resisting plates 704. The third power component 701 adopts a cylinder, which has a simple structure and is convenient to arrange.

[0066] Working principle: Before horizontal strapping, the third power component 701 extends, driving the resisting rod 703 and the resisting plate 704 to move synchronously. The shaping components 7 located on opposite sides of the strapping frame 302 clamp the bag-shaped curves 902 between the resisting plates 704, thereby eliminating the gaps between the bag-shaped curves 902. Since the resisting plate will contact the arc-shaped convex surface of the bag-shaped curve, the resisting plate 704 is designed into two upper and lower ones; in addition, the purpose of setting a certain distance between the upper and lower resisting plates 704 is to allow the strapping tape 10 to pass through.

[0067] From the above structure and working principle, it can be seen that before horizontally strapping the curved blocks of each layer, the present utility model can eliminate the gaps and shape the curved blocks of each layer layer by layer through the shaping component, eliminate the gaps between the bag-shaped curves, so that the curved blocks of each layer are densely arranged and stacked, thereby improving the stability of the curved block strapping and the stability of the curved block stack.

[0068] Since the bag-shaped curves produced by the koji-making machine are not all of the same thickness and there are small errors, the widths of the bag-shaped curves stacked on each layer of the tray are inconsistent. Coupled with the fact that the extending distance of the third power component is certain, there will be a situation where some rows of curved blocks are clamped too tightly and the curved blocks are damaged; there will also be a situation where some rows of curved blocks are clamped too loosely and the fixing effect cannot be achieved. For this reason, referring to Figure 7 and Figure 8 , this embodiment is further provided with a floating component 8, which is used to make the resisting rod 703 automatically adapt to different curved block thicknesses.

[0069] Specifically, referring to Figure 7 , the floating component 8 includes a long hole 801 horizontally arranged on the shaping bracket 702, the resisting rod 703 is movably connected to the long hole 801 through a screw 802, and a spring 803 is arranged on the resisting rod 703.

[0070] Working principle: Since the resistance rod is movably connected to the long hole by a screw, the distance of the long hole leaves a certain amount of movable space for the resistance rod. Coupled with the effect of the spring, this space has an adaptive effect and can automatically adapt to the different widths of each layer of the curved block to solve the problem of the curved block being clamped or too loose due to the inconsistent width of each layer of the curved block caused by the thickness error of the bag curved block.

[0071] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
