Description

Technical Field

[0001] The present invention relates to a paper machine, and particularly to a slurry molding system. Background Art

[0002] At present, paper tray products on the market, such as paper racks, paper cups, paper plates, paper bowls, etc., are mainly made of pulp. After operations such as pulp fishing, molding, hot pressing, and trimming, the paper tray products are completed. After manual inspection of the appearance, stacking of the paper tray products, and manual packing operations, the paper tray products can be stored in the warehouse.

[0003] However, the existing operation process still has the following disadvantages when manufacturing paper tray products:

[0004] 1. The existing pulp fishing operation, hot pressing operation, and trimming operation are independently completed by different machines. Therefore, the semi-finished pulp products need to be transferred between various machines, which is quite time-consuming and labor-intensive, and is extremely uneconomical.

[0005] 2. As disclosed in a wet paper fiber molding machine disclosed in Taiwan Patent No. M603476, although the pulp fishing operation, hot pressing operation, and trimming operation have been integrated into one machine, when inspecting the appearance and packing the paper tray products, it is still carried out manually. Therefore, there is still room for improvement in terms of streamlining manpower and shortening the process time.

[0006] Refer to Figure 1 , in addition, taking an existing hot pressing mold 1 as an example, it mainly includes a hot pressing mold 11 for generating heat energy, and a receiving mold 12 detachably engaged with the hot pressing mold 11. The receiving mold 12 can adsorb a paper tray semi-finished product 10 with an attracting air flow to be engaged with the hot pressing mold 11, and after the paper tray semi-finished product 10 is heated to remove moisture and take shape, it is detached from the hot pressing mold 11, and the dried paper tray semi-finished product 10 is blown off with a jet air flow to achieve the purpose of demolding.

[0007] However, since irregular areas will adhere to the receiving mold 12 during the process of the paper tray semi-finished product 10 changing from wet to dry, during the process of blowing off the paper tray semi-finished product 10 with a jet air flow, the paper tray semi-finished product 10 is likely to shift and get stuck on the receiving mold 12. At this time, if the pressure of the jet air flow is too large, it will penetrate the bottom of the paper tray semi-finished product 10. If the pressure of the jet air flow is too small, the paper tray semi-finished product 10 cannot be smoothly demolded, resulting in the inability to improve the yield or causing troubles in the process. Summary of the Invention

[0087] The transfer rail frame 821 moves between a loading position (such as Figure 8 the transfer rail frame 821 represented by the solid line in the lower left) and an unloading position (such as Figure 8 the transfer rail frame 821 represented by the imaginary line in the upper right). At the loading position, the suction cups 823 on the first suction cup frame 822 suck the blank A1 away from the first trimming die 51 by suction air flow. At the unloading position, when the suction air flow is blocked, the suction cups 823 on the first suction cup frame 822 can release the blank A1, so that when m×n blanks A1 move from the loading position to the unloading position, they can be quickly transferred above the first conveyor belt 81.

[0088] The second transfer unit 83 has a second suction cup frame 831 pivotally provided on the frame 21. The second suction cup frame 831 has m×n suction cups 832 for generating suction air flow, and is in a first flipping position (such as Figure 8 the second suction cup frame 831 represented by the solid line) and a second flipping position (such asFigure 8 It rotates between the second sucker brackets 831 represented by imaginary lines. When in the first flipping position, the second sucker bracket 831 is spaced from the first sucker bracket 822 located at the discharging position along the height direction Z, and each sucker 832 of the second sucker bracket 831 faces the first sucker bracket 822 and is adapted to adsorb the second surface A12 of its respective blank A1. When in the second flipping position, the second sucker bracket 831 is spaced from the first sucker bracket 822 located at the discharging position along the length direction X, and the suckers 832 of the second sucker bracket 831 face the first conveyor belt 81. After the suction air flow is blocked, the blank A1 is released, so that all the blanks A1 quickly stand upside down on the first conveyor belt 81 with one flipping action.

[0089] The second conveyor belt 84 is arranged between the first conveyor belt 81 and the packing area 205 and extends along the length direction X, and is used for conveying the blank A1 to pass through the imaging range of the second imaging unit 62 along the length direction X.

[0090] The third transfer unit 85 is pivotally arranged between the first conveyor belt 81 and the second conveyor belt 84 and has a plurality of sucker row rods 851. Each sucker row rod 851 has m suckers 852 for generating a suction air flow. Each sucker row rod 851 rotates between a first horizontal row position (such as Figure 9 the sucker row rod 851 at the 9 o'clock direction), a first vertical row position (such as Figure 9 the sucker row rod 851 at the 6 o'clock direction), a second horizontal row position (such as Figure 9 the sucker row rod 851 at the 3 o'clock direction) and a second vertical row position (such as Figure 9 the sucker row rod 851 at the 12 o'clock direction). In this embodiment, the included angle is 90 degrees. When in the first horizontal row position, the suckers 852 on the corresponding sucker row rod 851 face the first conveyor belt 81 and are used for adsorbing m blanks A1 arranged in a row along the width direction Y on the first conveyor belt 81. When in the first vertical row position, the suckers 852 on the corresponding sucker row rod 851 are within the imaging range of the first imaging unit 61. When in the second horizontal row position, the corresponding sucker row rod 851 is spaced from the first conveyor belt 81 along the length direction X. When in the second vertical row position, the suckers 852 of the corresponding sucker row rod 851 face the second conveyor belt 84. After the suction air flow is blocked, the blank A1 is released and arranged on the second conveyor belt 84 along the length direction X, so that all the blanks A1 are arranged on the second conveyor belt 84 in several times with n commutation and arrangement actions.

[0091] The fourth transfer unit 86 is disposed between the second conveyor belt 84 and the packing area 205, and has a hollow tube 861 in an inverted U shape for air flow, and a blowing group 864 for jetting air toward the hollow tube 861. The hollow tube 861 has an inlet 862 facing the second conveyor belt 84 and an outlet 863 opposite to the inlet 862. The inlet 862 allows air to enter, and the outlet 863 allows air to discharge. Each green body A1 enters the hollow tube 861 with the air flow from the inlet 862, and is inverted during the movement toward the outlet 863. After being discharged from the outlet 863, it enters the stacking space 760 from the stacking inlet 761 of the sleeve 76 along the height direction Z and is stacked in a row.

[0092] Refer to Figure 2 and Figure 9 , the central control device 9 is installed on the frame 21 and includes a first exclusion unit 91, a second exclusion unit 92, and a controller 93 electrically connected to the pulp fishing device 3, the automatic demolding device 4, the trimming device 5, the detection device 6, the packing device 7, the transfer device 8, the first exclusion unit 91, and the second exclusion unit 92.

[0093] In this embodiment, the first exclusion unit 91 is installed between the third transfer unit 85 and the second imaging unit 62 and has m pressing cylinders 911. Each pressing cylinder 911 has a telescopic dial rod 912 for dialing defective products away from the suction cup row rod 851 located at the second horizontal row position.

[0094] In this embodiment, the second exclusion unit 92 is installed on one side of the second conveyor belt 84 and is a nozzle for generating jet air flow to exclude defective products on the second conveyor belt 84. It should be noted that the second exclusion unit 92 is not limited to being a nozzle. In other variations of this embodiment, it can also be a pressing cylinder having a dial rod for dialing defective products away from the second conveyor belt 84.

[0095] When the controller 93 determines that the corresponding green body A1 is a defective product based on the detection data, it controls the first rejection unit 91 to reject the defective product on the suction cup row bar 851 at the second horizontal row position, or controls the second rejection unit 92 to reject the defective product on the second conveyor belt 84. In this embodiment, the detection data of the first imaging unit 61 includes the defect area of the first surface A11 of each green body A1, and the detection data of the second imaging unit 62 includes the defect area of the second surface A12 of each green body A1. And when the defect area of the first surface A11 of each green body A1 ÷ the total area of the first surface A11 ≥ 1% - 5%, the controller 93 determines it as a defective product, and when the defect area of the second surface A12 of each green body A1 ÷ the total area of the second surface A12 ≥ 1% - 5%, it determines it as a defective product.

[0096] It should be noted that the aforementioned defects can be cracks, stains, etc., and the calculated value for determining good or defective products is not limited to 1% - 5%. In other variations of this embodiment, it can be less than 1% or more than 5% according to different practical requirements.

[0097] Refer to Figure 4 、 Figure 8 、 Figure 9 and Figure 11 It should be noted that the diameter of each of the suction cups 451, 823, 832, 852 is between 10 mm and 40 mm, and the suction force is between 3.5 and 94 Newtons. In this embodiment, a switching valve unit (not shown in the figure) is used to connect the first channel 321, the second channel 411, the third channel 431, the suction cups 451, 823, 832, 852 to a vacuum pump (not shown in the figure) to achieve the negative pressure effect of generating an attracting air flow, and to connect the first channel 321, the blowing group 864, the second rejection unit 92 to a pressure pump (not shown in the figure) through the switching valve unit (not shown in the figure) to achieve the positive pressure effect of generating a jet air flow.

[0098] During specific implementation, the controller 93 can also be electrically connected to at least the third transfer unit 85, the first imaging unit 61, the second imaging unit 62, the first rejection unit 91, and the second rejection unit 92.

[0099] The following describes, in combination with the above embodiments, how the present invention controls the slurry scooping device 3, the automatic demolding device 4, the edge trimming device 5, the detection device 6, the packaging device 7, the transfer device 8, the first rejection unit 91, and the second rejection unit 92 by the controller 93 to perform a one - stop production process as follows:

[0100] Refer to Figure 2, Figure 3 , drive the slurry scooping die 32 to scoop an appropriate amount of slurry in the slurry bucket 31, and after removing most of the moisture in the slurry by the suction air flow in the first channel 321, drive the first blank receiving die 41 to move along the first linear slide rail 22 to above the slurry scooping die 32, then drive one of the first blank receiving die 41 and the slurry scooping die 32 to be aligned with each other. Then, suck the green blank unit A away from the slurry scooping die 32 by the suction air flow in the second channel 411.

[0101] Refer to Figure 2 , Figure 5 , drive the first blank receiving die 41 to move along the first linear slide rail 22 to above the hot pressing die 42, then drive the first blank receiving die 41 to move along the height direction Z to be aligned with the hot pressing die 42, so that during the hot pressing process of the green blank unit A, the residual moisture is removed and shaped. Then, suck the green blank unit A away from the hot pressing die 42 by the suction air flow in the second channel 411.

[0102] Refer to Figure 2 , Figure 6 , drive the first blank receiving die 41 to move along the first linear slide rail 22 to above the second blank receiving die 43, then drive one of the first blank receiving die 41 and the second blank receiving die 43 to move along the height direction Z to be aligned with each other. Then, during the process of moving away from each other, push the green blank unit A to move in a direction away from the first blank receiving die 41 by the jet air flow in the second channel 411. At the same time, suck the green blank unit A away from the first blank receiving die 41 by the suction air flow in the third channel 431 and transfer the green blank unit A to the second blank receiving die 43. Thus, during the process of one suction and one release, assist the green blank unit A to smoothly separate from the first blank receiving die 41 and be adsorbed on the second blank receiving die 43.

[0103] Refer to Figure 7 and Figure 8 , control the demolding rail frame 44 to move along the second linear slide rail 23 to be adjacent to the second blank receiving die 43, then drive the demolding suction cup frame 45 to move along the height direction Z to adsorb the green blank unit A with the suction cup 451. Then, carry the green blank unit A away from the second blank receiving die 43 along the height direction Z, and drive the demolding rail frame 44 to move along the second linear slide rail 23 to be adjacent to the first trimming die 51. Then, drive the demolding suction cup frame 45 to move along the height direction Z to be adjacent to the first trimming die 51, and after blocking the suction air flow, release the green blank unit A onto the first trimming die 51.

[0104] Control the second trimming die 52 to move along the height direction Z to align with the first trimming die 51, and after cutting the initial blank unit A to form the separated blank A1, control the second trimming die 52 to move away from the first trimming die 51.

[0105] Control the transfer rail frame 821 to move along the second linear slide rail 23 to the feeding position adjacent to the first trimming die 51, then drive the first suction cup frame 822 to move along the height direction Z to adsorb the first surface A11 of the blank A1 with the suction cup 823. Then, carry the blank A1 away from the first trimming die 51 along the height direction Z, and drive the transfer rail frame 821 to move along the second linear slide rail 23 to the discharging position adjacent to the first conveyor belt 81. Then, drive the second suction cup frame 831 at the first flipping position to move along the height direction Z to be adjacent to the first suction cup frame 822. Next, adsorb and hold the second surface A12 of the blank A1 with the suction cup 832, and block the suction air flow of the suction cup 823 to make the suction cup 823 release the blank A1. Then, drive the second suction cup frame 831 to rotate to the second flipping position, and after blocking the suction air flow of the suction cup 832, release the blank A1, so that all the blanks A1 are quickly inverted on the first conveyor belt 81 in one flipping action.

[0106] Refer to Figure 9 And Figure 10 , control the third transfer unit 85 to rotate, and when each suction cup row bar 851 rotates to the first horizontal row position, adsorb the second surface A12 of m blanks A1 arranged in a column with the suction cup 852.

[0107] When each suction cup row bar 851 carries the blank A1 to rotate to the first vertical row position, control the first camera unit 61 to move along the length direction X, and during the movement, photograph the first surface A11 of the blank A1 on each suction cup 852, and output respective detection data for each blank A1. At this time, the controller 93 will judge whether the defective area of the first surface A11 of each blank A1 ÷ the total area of the first surface A11 ≥ 1 - 5% according to the detection data of each blank A1. If so, it is judged as a defective product, and if not, it is judged as a good product.

[0108] When each suction cup row bar 851 carries the blank A1 to rotate to the second horizontal row position, control the lever 912 of the corresponding pressing cylinder 911 to push the defective product away from the corresponding suction cup 852.

[0109] When each of the sucker rows 851 carrying the blank A1 rotates to the second longitudinal row position, the suction air flow of the suckers 852 located at the second longitudinal row position is blocked, and the blank A1 determined to be a good product is released and arranged along the length direction X on the second conveyor belt 84, so that all the blanks A1 are arranged on the second conveyor belt 84 in batches through n times of commutation and arrangement actions.

[0110] During the process of the second conveyor belt 84 conveying the blank A1 past the second imaging unit 62, the second imaging unit 62 is controlled to photograph the second surface A12 of each passing blank A1 at different angles, and five detection data are output for each blank A1. At this time, the controller 93 will judge whether the defective area of the second surface A12 of each blank A1 divided by the total area of the first surface A11 is ≥ 1 - 5% according to the detection data of each blank A1. If so, it is judged as a defective product; if not, it is judged as a good product.

[0111] After the second conveyor belt 84 conveys the blank A1 past the second imaging unit 62, the second rejection unit 92 is controlled to eject air flow to remove the defective products on the second conveyor belt 84.

[0112] Refer to Figure 11 and Figure 12 When the second conveyor belt 84 conveys the blank A1 determined to be a good product to the end of the travel, the blowing group 864 is controlled to generate an ejection air flow, so that each blank A1 moves from the placement port 862 towards the discharge port 863 along with the air flow, and is inverted during the movement, and enters the stacking space 760 from the stacking inlet 761 of the sleeve 76 along the height direction Z and is stacked in a row.

[0113] The swing arm group 771 is controlled to drive the discharge outlet 762 of the sleeve 76 towards the packaging space 71, and the push rod 781 of the pushing unit 78 is controlled to push the stacked blanks A1 to separate from the sleeve 76 from the discharge outlet 762, and enter the packaging bag B in the packaging space 71 from the bag mouth B2. Finally, the heat pressing group 791 is controlled to heat press the bag mouth B2 of the packaging bag B, so that the bag mouth B2 is melted and sealed.

[0114] In this way, the operations of scooping → hot pressing → demoulding → trimming → flipping → aligning → testing → stacking → packaging, etc. are completed in a one-stop manner in a fully automated process. After packaging is completed, it is only necessary to take out the packaging bag B containing the blank A1 and replace it with a new packaging bag B, and the clamping unit 74 can be controlled to clamp the bag opening B2 of the packaging bag B, and drive the packaging bag B to extend along the pull rod 72 in the opposite direction of the positioning unit 73, and the positioning unit 73 and the clamping unit 74 can be used to propel the packaging bag B in the packaging space 71, so that the stacked blank A1 can enter the packaging bag B from the bag opening B2.

[0115] See also Figure 8 It should be noted that the first suction cup frame 822 is not limited to being driven by the transfer rail frame 821. In other variations of this embodiment, the first suction cup frame 822 may also be driven by the transfer rail frame 821. Figure 13 As shown, a mechanical arm 824 connected to the first suction cup frame 822 drives the first suction cup frame 822 to move between the feeding position and the discharging position. In this way, m×n blanks A1 can be quickly transferred to the first conveyor belt 81 when the mechanical arm 824 rotates substantially 180 degrees. However, the rotation space of the mechanical arm 824 is relatively small. Figure 8 As for the moving space of the transfer rail frame 821, the required space is smaller, which can improve the space efficiency and shorten the moving time.

[0116] In addition, the method of reversing the blank A1 is not limited to the following: Figure 8 As shown, the blank A1 is flipped by rotating the second suction cup frame 831. In other variations of this embodiment, the blank A1 may also be flipped as shown in FIG. Figure 14 and Figure 15As shown, the first conveyor belt 81 has a first conveying section 811 and a second conveying section 812 spaced along the length direction X. The second transfer unit 83 is pivotally provided on the frame 21 and is located between the first conveying section 811 and the second conveying section 812. The second transfer unit 83 has a plurality of deflector plates 834 formed on a circumferential surface 833 and having an inclination angle, and m suction cups 835 provided on the deflector plates 834 for generating a suction air flow. Each deflector plate 834 rotates between a receiving position and a flipping position separated by an included angle of 180 degrees. In the receiving position, each deflector plate 834 is adjacent to the first conveying section 811 and receives m green bodies A1 from the first conveying section 811, so that the m green bodies A1 on the first conveying section 811 move to the suction cups 835 of the corresponding deflector plates 834 along the inclination angle of the corresponding deflector plates 834. In the flipping position, each deflector plate 834 faces the second conveying section 812, and after the suction air flow of the suction cups 835 is blocked, the corresponding m green bodies A1 are released and stand upside down on the second conveying section 812, so that all the green bodies A1 stand upside down on the second conveying section 812 in n flipping operations. Thus, Figure 14 the rotation space of the second transfer unit 83 with respect to Figure 8 the rotation space of the second suction cup holder 831 requires a smaller space, which can improve the space efficiency. However, since it is necessary to rotate n times between the receiving position and the flipping position to flip all the green bodies A1, more flipping time is required.

[0117] Furthermore, the method of stacking the green bodies A1 is not limited to as Figure 11 shown. In other variations of this embodiment, it can also be as Figure 2 and Figure 16As shown, the second conveyor belt 84 has a first conveying section 841 adjacent to the detection area 204 and a second conveying section 842 disposed between the first conveying section 841 and the packing area 205. The first conveying section 841 is used to receive the blank A1 released by the third transfer unit 85. The height of the second conveying section 842 along the height direction Z is less than the height of the first conveying section 841 along the height direction Z, and is suitable for receiving the blank A1 that falls and topples from the first conveying section 841. The transfer device 8 further includes a baffle 87. The baffle 87 is pivotally provided on the frame 21 rotatably and is located on the side of the second conveying section 842 away from the first conveying section 841, and is used to block the blank A1 on the second conveying section 842, so that the blank A1 is stacked in a row along the direction opposite to the baffle 87 by the baffle 87, and after the stacked blank A1 is separated, the stacked blank A1 moves with the second conveying section 842 towards the packing area 205 to be moved and inserted into the sleeve 76. Thus, compared with Figure 11 the hollow tube 861, the purpose of stacking the blank A1 along the length direction X can be achieved with a more concise structure.

[0118] In addition, the method of stacking the blank A1 can also be as Figure 2 , Figure 17 and Figure 18 shown. The fourth transfer unit 86 is pivotally provided between the second conveyor belt 84 and the packing area 205, and has a plurality of suction cup stacking rods 865 and a receiving tray 867 located at the end of the travel of the second conveyor belt 84. The receiving tray 867 is used to receive the blank A1 entering from the second conveyor belt 84, and when the depth along the length direction X only allows one blank A1 to be accommodated and the width along the width direction Y only allows m blanks A1 to be accommodated, m blanks A1 are pushed against each other to be arranged in a row along the width direction Y. Each suction cup stacking rod 865 has m suction cups 866 for generating suction air flow. The suction cup stacking rod 865 rotates between a release position and three stacking positions separated by an angle. At the release position, the m suction cups 866 on each suction cup stacking rod 865 face the receiving tray 867 and adsorb m blanks A1 arranged along the width direction Y on the receiving tray 867. At any stacking position, the suction air flow of the suction cups 866 of each suction cup stacking rod 865 is blocked, and the blank A1 is released to be stacked along the height direction Z. Thus, compared with Figure 11 or Figure 16 the stacking method, more blanks A1 can be stacked in a shorter time, but more packing devices 7 (such as Figure 12 ) are required to cooperate, and the equipment cost is higher.

[0119] Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

[0120] 1. The present invention provides a slurry molding system with continuous and fully automatic processes, capable of fully automatically producing the green body A1 with equipment similar to an assembly line, thereby greatly improving production efficiency and reducing labor costs.

[0121] 2. And importantly, when the present invention performs automatic demolding, the injection air flow in the second channel 411 can be used to push the green body unit A to move in a direction opposite to the first receiving mold 41, and at the same time, the suction air flow in the third channel 431 can be used to suck the green body unit A away from the first receiving mold 41. Thus, in the process of one suction and one release, it can assist the green body unit A to smoothly separate from the first receiving mold 41, thereby improving the integrity of the green body unit A during separation and greatly improving the yield of the green body unit A.

[0122] The above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still fall within the scope of the present invention.
