Description

Technical Field

[0001] This invention relates to the field of shiitake mushroom spawn production, specifically to a method for taking out a spawn bag. Background Technology

[0002] Automated bag-removal systems can automatically and systematically place bags for producing shiitake mushroom spawn onto the filler tubes containing the substrate (raw material). However, current automated bag-removal solutions only support the automated removal of bags of one specification or size, requiring users to purchase different models of equipment when producing different types of mushroom spawn. Therefore, it is necessary to address this issue. Summary of the Invention

Adjust the upper adsorption component and the bag groove to be far apart so that the bag adsorbed by the upper adsorption component is removed from the bag groove.

[0008] S30: Adjust the upper and lower adsorption components to be arranged in a corresponding manner, and adjust the adsorption components to be closer to each other so that the bag opening is clamped by the upper and lower adsorption components and the lower adsorption component adsorbs the lower bag surface at the bag opening.

[0013] In operation S20, the bag groove is fixedly set, and the upper adsorption component is adjusted to move up and down along the Z direction so that the upper adsorption component and the bag groove move closer and further apart. The Z direction is the vertical direction.

[0014] In operation S30, the lower adsorption component is fixedly set, and the upper adsorption component is adjusted to move along the Y direction so that the upper adsorption component and the lower adsorption component are arranged correspondingly above and below. The upper adsorption component is adjusted to move up and down along the Z direction so that the adsorption component and the lower adsorption component move closer and further away from each other. The Y direction is a horizontal direction that is perpendicular to the X direction.

[0015] In operation S40, the first and second bag-taking components are adjusted to move along the X direction and extend into the bag opening, and the second bag-taking component is adjusted to move along the Y direction relative to the first bag-taking component to open the bag opening.

[0016] In operation S40, the first and second bag-taking components are adjusted to move along the X and Y directions to place the bag opening onto the packing tube.

[0029] like Figure 1 , 2As shown, a method for taking out a bag 00, which is a long strip-shaped plastic bag used for producing shiitake mushroom spawn bags, includes the following operations: Adjusting the state of the upper adsorption component so that the adsorption range of the upper adsorption component is consistent with the length of the bag 00, and placing the bag 00 horizontally in a stacked manner within the bag 00 groove 30. Specifically, the upper adsorption component can be configured to consist of a first upper adsorption member 11 that adsorbs the bag opening end of the bag 00 and a second upper adsorption member 12 that adsorbs the bag bottom end of the bag 00. The adsorption range of the upper adsorption component is adjusted by adjusting the positional relationship between the first upper adsorption member 11 and the second upper adsorption member 12. Preferably, the second upper adsorption component is configured to slide along the X direction, and the positional relationship between the first upper adsorption member 11 and the second upper adsorption member 12 is adjusted by adjusting the movement of the second adsorption component along the X direction, where the X direction is a horizontal direction consistent with the length direction of the bag 00 groove 30.

[0030] Adjust the upper adsorption component and the bag body 00 groove 30 to be arranged correspondingly in the upper and lower positions. Adjust the adsorption component and the bag body 00 groove 30 to be closer to each other, so that the upper adsorption component is in contact with the uppermost bag body 00 in the bag body 00 groove 30 and adsorbs the upper bag surface at both ends of the bag body 00.

Adjust the upper and lower adsorption components 21 to move further apart so that the bag opening of the bag body 00 is opened. Specifically, during the process of moving the upper and lower adsorption components 21 further apart, the bottom of the bag body 00 can be separated from the upper adsorption component. Fix the lower adsorption component 21 in place, and move the upper adsorption component along the Y direction so that the upper and lower adsorption components 21 are arranged correspondingly. Adjust the upper adsorption component along the Z direction to move it closer to and further away from the adsorption components 21. The Y direction is a horizontal direction perpendicular to the X direction.

[0032] Adjust the first and second bag-taking components, which are in a close proximity, to extend into the opening of the bag body 00. Then, adjust the first and second bag-taking components to move away from each other, opening the opening of the bag body 00 and separating it from the upper and lower adsorption components 21. Move the first and second bag-taking components to place the opening of the bag body 00 onto the packing tube 01. Fill the bag body 00 with matrix through the packing tube 01, and then send the matrix-filled bag body 00 to the subsequent processing step. Specifically, adjust the first and second bag-taking components to move along the X direction to extend into the opening of the bag body 00, and adjust the second bag-taking component 42 to move along the Y direction relative to the first bag-taking component 41 to open the opening of the bag body 00. Adjust the first and second bag-taking components to move along the X and Y directions to place the opening of the bag body 00 onto the packing tube 01.

The lower surfaces of the first upper adsorption component 11 and the second upper adsorption component 12 are provided with pores for adsorbing the air from the bag 00, and the upper surface of the lower adsorption assembly 21 is also provided with pores for adsorbing the air from the bag 00. An elastic material layer is provided on the outer surface of the adsorption component that contacts the bag 00 to prevent the bag 00 from being crushed. The first upper adsorption component 11 and the second upper adsorption component 12 are connected by a telescopic connecting tube 19. The first upper adsorption component 11 and the lower adsorption assembly 21 are respectively connected to an air extraction device through a first tube and a third tube. A bag-separating bracket 50 is also provided on the mounting base. The bag-separating bracket 50 is movably mounted on the X mounting base 16 along the Z direction. A bag-pressing rod 51 arranged along the Y direction is provided at the lower part of the bag-separating bracket 50.

The above-mentioned structure provided by the present invention is applied to an automatic production equipment for shiitake mushroom spawn bags. Parts not described in detail adopt the solutions in existing automated shiitake mushroom spawn bag equipment.

[0034] In use, the distance between the first and second adsorption parts is first adjusted to match the length of the bag 00 to be used. Then, the X-bracket is moved to the upper side of the slot 30 of the bag 00. Figure 2As shown, the X cylinder 13 is activated to lower the X support. The first upper adsorption component 11 and the second upper adsorption component 12 adsorb the upper surface of the uppermost bag 00 in the bag 00 slot 30. The electromagnet 53 is energized to adsorb and fix the bag separating support 50. Then, the X cylinder 13 is activated to raise the X support, so that the bag 00 to be picked up is moved out of the bag 00 slot 30. The Y cylinder 14 is activated to move the X support along the Y direction until the first upper adsorption component 11 and the lower adsorption component 21 are arranged correspondingly on the top and bottom. The X cylinder 13 is activated to lower the X support, clamping the bag opening end of the bag 00 between the first upper adsorption component 11 and the lower adsorption component 21. The lower adsorption component 21 adsorbs the lower surface of the bag opening end of the bag 00. Then, the X support is adjusted to move up to a preset height, so that the bag opening of the bag 00 is opened. At the same time, the electromagnet 53 is de-energized, and the bag separating support 50 lowers the bag pressing rod to separate the bottom end of the bag 00 from the second upper adsorption component 12. Activate cylinders V43 and W44 to move mounting base U45, allowing the first and second bag-removing components to extend into the bag opening of bag 00. Activate cylinder U to separate the first and second bag-removing components. Simultaneously, activate cylinders V43 and W44 to move mounting base U45, thereby separating bag 00 from the first upper adsorption component 11 and lower adsorption assembly 21, and placing bag 00 onto the packing tube 01. Adjust the X-bracket to return to its initial position for the next bag-removing operation. The packing mechanism fills the bag 00 with matrix, and this process is repeated. When changing to a different model of bag 00, simply rotate screws X18 and Y25 before the initial operation to adjust the second upper adsorption component 12 and X-support block 24 to their respective positions.
