Description

Technical Field

[0001] The present application relates to the field of printing technology, and particularly relates to a double-feeding conveyor and a paper bag printing device. Background Art

[0002] Currently, the types of paper bags include corded paper bags and cordless paper bags. Whether it is a corded paper bag or a cordless paper bag, patterns need to be printed on the paper bag. When the paper bag printing device prints the pattern on the paper bag, it prints a single paper bag. Therefore, when the conveyor of the paper bag printing device conveys the paper bags, it is necessary to convey multiple stacked paper bags to the position where the printing machine of the paper bag printing device is located in the form of a single paper bag, so that the printing machine can print the pattern on the paper bag. When the conveyor of the conventional paper bag printing device conveys the corded paper bags, since multiple corded paper bags are stacked together, when the double-feeding conveyor of the paper bag printing device conveys the corded paper bags, the ropes of multiple corded paper bags are prone to knotting, entanglement, and position deviation, resulting in the inability to normally convey the corded paper bags.

[0045] In this embodiment, the first material includes a corded paper bag.

[0046] In this embodiment, the second material includes a cordless paper bag or a paper cup sleeve.

[0047] In this embodiment, the lifting device is located below the second conveying device 400.

[0048] In this embodiment, referring to Figure 5 , Figure 6 , the piece separating and transferring device 600 includes a suction cup assembly 610, a horizontal moving assembly 620, a first driving assembly 630, a vertical moving assembly 640, and a second driving assembly 650; the suction cup assembly 610 is used for sucking the first material; the horizontal moving assembly 620 is connected to the suction cup assembly 610 and is used for driving the suction cup assembly 610 to move horizontally; the first driving assembly 630 is connected to the horizontal moving assembly 620 and is used for driving the horizontal movement; the vertical moving assembly 640 is installed on the machine table 100, and the vertical moving assembly 640 is connected to the horizontal moving assembly 620 and is used for driving the horizontal moving assembly 620 to move up and down; the second driving assembly 650 is connected to the vertical moving assembly 640 and is used for driving the vertical moving assembly 640 to move up and down. By setting that the piece separating and transferring device 600 includes the suction cup assembly 610, the horizontal moving assembly 620, the first driving assembly 630, the vertical moving assembly 640, and the second driving assembly 650, the suction cup assembly 610 can suck a single piece of the first material, and under the action of the first driving assembly 630 and the second driving assembly 650, it is ensured that the first material can be transferred onto the third conveying device 500.

[0049] During operation, the second driving assembly 650 drives the vertical moving assembly 640 to work, and the vertical moving assembly 640 drives the horizontal moving assembly 620 to move downward. At this time, the horizontal moving assembly 620 drives the suction cup assembly 610 to move downward. When the suction cup assembly 610 contacts the single piece of the first material at the top layer of the stacked multiple pieces of the first material, the suction cup assembly 610 sucks the single piece of the first material at the top layer. Then the second driving assembly 650 drives the vertical moving assembly 640 to move upward, so that the plane where the first material is located is not lower than the plane where the third conveying device 500 is located. The first driving assembly 630 works, and the first driving assembly 630 drives the horizontal moving assembly 620 to move towards the third conveying device 500, so that at least a part of the single piece of the first material sucked by the suction cup assembly 610 is located on the third conveying device 500, thereby realizing the conveying of the single piece of the first material.

[0050] In this embodiment, referring to Figure 1 , Figure 2 , Figure 5 and Figure 6, the component transfer device 600 further includes: a housing 660 and a first connecting member 670. The housing 660 is fixed to the machine table 100. The vertical movement assembly 640 and the horizontal movement assembly 620 are located inside the housing 660. A slot 661 is provided on the housing 660. One end of the first connecting member 670 is fixed to the suction cup assembly 610, and the other end of the first connecting member 670 is fixed to the horizontal movement assembly 620. The slot 661 includes a horizontal guiding slot 6611 and a vertical guiding slot 6612, and the horizontal guiding slot 6611 communicates with the vertical guiding slot 6612. Since when the component transfer device 600 transfers a single piece of the first material to the third conveying device 500, the component transfer device 600 will move a preset distance in the direction of the third conveying device 500, so as to ensure that the single piece of the first material can be located on the third conveying device 500 and ensure that the third conveying device 500 can normally convey the first material. However, since the vertical movement assembly 640 and the horizontal movement assembly 620 are located inside the housing 660, the housing 660 will limit the movement direction of the suction cup assembly 610. Therefore, a slot 661 is provided on the housing 660, and the slot 661 is provided to include a horizontal guiding slot 6611 and a vertical guiding slot 6612, and the horizontal guiding slot 6611 communicates with the vertical guiding slot 6612, so that the first connecting member 670 can drive the suction cup assembly 610 to move in the vertical direction and the horizontal direction, thereby ensuring that the single piece of the first material adsorbed by the suction cup assembly 610 can be transferred to the third conveying device 500.

[0051] During operation, the second drive assembly 650 drives the vertical movement assembly 640 to work. The vertical movement assembly 640 drives the first connecting member 670 and the horizontal movement assembly 620 to move up and down. When the first connecting member 670 moves to the position where the connection area of the horizontal guiding slot 6611 and the vertical guiding slot 6612 is located, the first drive assembly 630 drives the horizontal movement assembly 620 to work. The horizontal movement assembly 620 drives the first connecting member 670 and the suction cup assembly 610 to move in the direction of the third conveying device 500. At this time, the first connecting member 670 enters the horizontal guiding slot 6611, and then the suction cup assembly 610 places the adsorbed single piece of the first material on the third conveying device 500. The third conveying device 500 conveys the single piece of the first material. After that, the horizontal movement assembly 620 is controlled to drive the suction cup assembly 610 to move in the direction away from the third conveying device 500. The first connecting member 670 moves to the area where the vertical guiding slot 6612 is located. Then, the vertical movement assembly 640 is controlled to move downward, and the suction cup assembly 610 adsorbs the single piece of the first material at the top layer of the stacked multiple pieces of the first material, and the cycle is repeated.

[0052] In this embodiment, referring to Figure 3 and Figure 4, the piece separation and conveying device 300 includes a base 310, a fourth conveying device 320, and a piece separation device 330.

[0053] In this embodiment, referring to Figure 3 and Figure 4 , the fourth conveying device 320 includes a conveyor belt; the piece separation device 330 includes a bracket 331 and a first stopper 332. The bracket 331 is fixed to the base 310, the first stopper 332 is connected to the bracket 331, the first stopper 332 is located above the conveyor belt, and there is a gap between the first stopper 332 and the conveyor belt. The gap is used for a single piece of the second material to pass through. By providing that the piece separation device 330 includes a bracket 331 and a first stopper 332, the bracket 331 is fixed to the base 310, the first stopper 332 is connected to the bracket 331, the first stopper 332 is located above the conveyor belt, and there is a gap between the first stopper 332 and the conveyor belt, the first stopper 332 can play a role in blocking the stacked second materials, and at the same time, it can ensure that a single piece can pass through the gap, thereby realizing the separation of the second materials.

[0054] It should be noted that the size of the gap is greater than the thickness of a single piece of the second material and less than the thickness of two pieces of the second material.

[0055] In this embodiment, the first stopper 332 includes a vertical portion, a bent portion, and a horizontal portion. The vertical portion is connected to the bracket 331. One side of the bent portion is connected to the vertical portion, and the other side of the bent portion is connected to the horizontal portion. The horizontal portion extends in the direction of the output side of the second conveying device 400. Wherein, the spacing is the distance between the conveyor belt and the horizontal portion. By providing that the first stopper 332 includes a vertical portion, a bent portion, and a horizontal portion, the vertical portion is connected to the bracket 331, one side of the bent portion is connected to the vertical portion, and the other side of the bent portion is connected to the horizontal portion. The horizontal portion extends in the direction of the output side of the second conveying device 400, so that the vertical portion can play a role in blocking the second material, and the bent portion can play a role in guiding the second material, thereby ensuring that the second material can move in the direction of the third conveying device 500.

[0056] In this embodiment, referring to Figure 3 and Figure 4 , the part separating device 330 further includes a second stopper 333. The second stopper 333 is disposed opposite to the first stopper 332, and a limiting groove is formed between the second stopper 333 and the first stopper 332.

[0057] In this embodiment, referring to Figure 3 and Figure 4 , the part separating device 330 further includes two third stoppers 334. The two third stoppers 334 are located on both sides of the fourth conveying device 320. The two third stoppers 334 are disposed opposite to each other, and the two third stoppers 334 are slidably connected to the between. By providing that the part separating device 330 further includes two third stoppers 334. The two third stoppers 334 are located on both sides of the fourth conveying device 320. The two third stoppers 334 are disposed opposite to each other, and the two third stoppers 334 are slidably connected to the between, so that the spacing between the two third stoppers 334 can be adjusted according to actual needs, ensuring that the part separating and conveying device 300 can convey second materials of different sizes, thereby increasing the types of materials conveyed by the double-feeding conveyor.

[0058] In this embodiment, referring to Figure 3 and Figure 4, the fourth conveying device 320 is inclined, and the height of the plane where the input side of the fourth conveying device 320 is located is higher than the height of the plane where the output side of the fourth conveying device 320 is located. By arranging the fourth conveying device 320 to be inclined and the height of the plane where the input side of the fourth conveying device 320 is located is higher than the height of the plane where the output side of the fourth conveying device 320 is located, the stacked second materials on the fourth conveying device 320 can have a tendency to move in a direction towards the second conveying device 400, so as to ensure that a single second material can move more easily to the spacing between the first stopper 332 and the conveyor belt, and be conveyed to the second conveying device 400 through the fourth conveying device 320.

[0059] Working principle:

[0060] When conveying the first material, this is the first working state. First, the first driving device drives the second conveying device 400 to move away from the part separating and transferring device 600, so that the input side of the second conveying device 400 is docked with the output side of the first conveying device 200. The stacked first materials are placed on the first conveying device 200, and the first conveying device 200 conveys the stacked first materials to the second conveying device 400. At this time, the first conveying device 200 pauses working. Then the lifting device drives the second conveying device 400 to move towards the part separating and transferring device 600, so that the multi-layer stacked first materials on the second conveying device 400 are close to the part separating and transferring device 600, enabling the part separating and transferring device 600 to separate the stacked first materials and transfer the separated first materials to the third conveying device 500. When all the multi-layer stacked first materials on the second conveying device 400 are transferred to the third conveying device 500, control the lifting device to work, so that the second lifting device drives the second conveying device 400 to move away from the part separating and transferring device 600, making the input side of the second conveying device 400 dock with the output side of the first conveying device 200. Then control the first conveying device 200 to enable the first conveying device 200 to continue conveying the stacked first materials to the second conveying device 400, thereby completing the conveying work of the single first material;

That is, the first materials of multiple corded paper bags in a stacked state can be separated into individual pieces by the piece - separating transfer device 600, and the separated single piece of the first material is transferred onto the third conveying device 500, so that a single corded paper bag can be conveyed to the position where the printing device is located, avoiding the problems that the ropes of multiple corded paper bags are prone to knotting, winding, and position deviation, resulting in the abnormal conveyance of the corded paper bags, and ensuring that the paper bag printing device can normally print a single corded paper bag.

[0066] In this embodiment, the first material includes a corded paper bag.

[0067] In this embodiment, the second material includes a cordless paper bag or a paper cup sleeve.

[0068] In this embodiment, referring to Figure 5 and Figure 6 , the part transfer device 600 includes a suction cup assembly 610, a horizontal movement assembly 620, a first drive assembly 630, a vertical movement assembly 640, and a second drive assembly 650; the suction cup assembly 610 is used to adsorb the first material; the horizontal movement assembly 620 is connected to the suction cup assembly 610 and is used to drive the suction cup assembly 610 to move horizontally; the first drive assembly 630 is connected to the horizontal movement assembly 620 and is used to drive the horizontal movement; the vertical movement assembly 640 is installed on the machine table 100, and the vertical movement assembly 640 is connected to the horizontal movement assembly 620 and is used to drive the horizontal movement assembly 620 to move up and down; the second drive assembly 650 is connected to the vertical movement assembly 640 and is used to drive the vertical movement assembly 640 to move up and down. By setting the part transfer device 600 to include the suction cup assembly 610, the horizontal movement assembly 620, the first drive assembly 630, the vertical movement assembly 640, and the second drive assembly 650, the suction cup assembly 610 can adsorb a single piece of the first material, and under the action of the first drive assembly 630 and the second drive assembly 650, it is ensured that the first material can be transferred onto the third conveyor device 500, so that the printing device above the third conveyor device 500 can print patterns on a single piece of the first material, reducing the risk of missed printing of the first material.

[0069] During operation, the second drive assembly 650 drives the vertical movement assembly 640 to work, and the vertical movement assembly 640 drives the horizontal movement assembly 620 to move downward. At this time, the horizontal movement assembly 620 drives the suction cup assembly 610 to move downward. When the suction cup assembly 610 contacts a single piece of the first material at the top layer of the stacked multiple pieces of the first material, the suction cup assembly 610 adsorbs the single piece of the first material at the top layer. Then, the second drive assembly 650 drives the vertical movement assembly 640 to move upward, so that the plane where the first material is located is not lower than the plane where the third conveyor device 500 is located. The first drive assembly 630 works, and the first drive assembly 630 drives the horizontal movement assembly 620 to move in the direction of the third conveyor device 500, so that at least a part of the single piece of the first material adsorbed by the suction cup assembly 610 is located on the third conveyor device 500. Then, the third conveyor device 500 conveys the single piece of the first material to the position where the printing device is located, ensuring that the printing device can print patterns on the single piece of the first material and reducing the risk of missed printing of the first material.

[0070] In this embodiment, referring toFigure 1 , Figure 2 , Figure 5 and Figure 6 , the sub-piece transfer device 600 further includes: a housing 660 and a first connecting member 670. The housing 660 is fixed to the machine table 100. The vertical moving assembly 640 and the horizontal moving assembly 620 are located inside the housing 660. A slot 661 is provided on the housing 660. One end of the first connecting member 670 is fixed to the suction cup assembly 610, and the other end of the first connecting member 670 is fixed to the horizontal moving assembly 620. The slot 661 includes a horizontal guiding slot 6611 and a vertical guiding slot 6612, and the horizontal guiding slot 6611 communicates with the vertical guiding slot 6612. Since when the sub-piece transfer device 600 transfers a single piece of the first material to the third conveying device 500, the sub-piece transfer device 600 will move a preset distance in the direction of the third conveying device 500, so as to ensure that the single piece of the first material can be located on the third conveying device 500 and ensure that the third conveying device 500 can normally convey the first material. However, since the vertical moving assembly 640 and the horizontal moving assembly 620 are located inside the housing 660, the housing 660 will limit the moving direction of the suction cup assembly 610. Therefore, a slot 661 is provided on the housing 660, and the slot 661 is provided to include a horizontal guiding slot 6611 and a vertical guiding slot 6612, and the horizontal guiding slot 6611 communicates with the vertical guiding slot 6612, so that the first connecting member 670 can drive the suction cup assembly 610 to move in the vertical direction and the horizontal direction, thereby ensuring that the single piece of the first material adsorbed by the suction cup assembly 610 can be transferred to the third conveying device 500.

[0071] During operation, the second driving assembly 650 drives the vertical moving assembly 640 to work. The vertical moving assembly 640 drives the first connecting member 670 and the horizontal moving assembly 620 to move up and down. When the first connecting member 670 moves to the position where the connecting area of the horizontal guiding slot 6611 and the vertical guiding slot 6612 is located, the first driving assembly 630 drives the horizontal moving assembly 620 to work. The horizontal moving assembly 620 drives the first connecting member 670 and the suction cup assembly 610 to move in the direction of the third conveying device 500. At this time, the first connecting member 670 enters the horizontal guiding slot 6611. Then the suction cup assembly 610 places the single piece of the first material adsorbed thereon on the third conveying device 500. The third conveying device 500 conveys the single piece of the first material. After that, the horizontal moving assembly 620 is controlled to drive the suction cup assembly 610 to move in the direction away from the third conveying device 500. The first connecting member 670 moves to the area where the vertical guiding slot 6612 is located. Then the vertical moving assembly 640 is controlled to move downward, and the suction cup assembly 610 adsorbs the single piece of the first material at the top layer of the stacked multiple pieces of the first material, and this process is repeated in a cycle.

[0079] Working principle:

[0080] When conveying the first material, this is the first working state. First, the first driving device drives the second conveying device 400 to move away from the part separating and transferring device 600, so that the input side of the second conveying device 400 is docked with the output side of the first conveying device 200. The stacked first materials are placed on the first conveying device 200, and the first conveying device 200 conveys the stacked first materials to the second conveying device 400. At this time, the first conveying device 200 pauses working. Then, the lifting device drives the second conveying device 400 to move towards the part separating and transferring device 600, so that the multi-layer stacked first materials located on the second conveying device 400 are close to the part separating and transferring device 600, enabling the part separating and transferring device 600 to separate the stacked first materials and transfer the separated first materials to the third conveying device 500. The third conveying device 500 conveys the first materials to the position where the printing device is located, and the printing device prints patterns on the single first material, thus completing the printing of the patterns on the first materials; when all the multi-layer stacked first materials located on the second conveying device 400 are transferred to the third conveying device 500, control the lifting device to work, so that the second lifting device drives the second conveying device 400 to move away from the part separating and transferring device 600, making the input side of the second conveying device 400 dock with the output side of the first conveying device 200. Then control the first conveying device 200 to enable the first conveying device 200 to continue conveying the stacked first materials to the second conveying device 400;

[0081] When conveying the second material, it is in the second working state at this time. The lifting device drives the second conveying device 400 to move away from or towards the part separating and transferring device 600, so that the input side of the second conveying device 400 is docked with the output side of the part separating conveying device 300, and the output side of the second conveying device 400 is docked with the input side of the third conveying device 500. Then, control the part separating conveying device 300 to work, so that the part separating conveying device 300 conveys a single-piece second material onto the second conveying device 400.
