[0026] In order to solve the problem of poor accuracy of the position of the ton package in the prior art, the present utility model provides a ton package conveying system.

[0027] Such as Figures 1 to 5As shown in the figure, the bulk bag conveying system includes a base 10, a conveying device 20 for conveying bulk bags, and a plurality of side pushing devices 30. The conveying device 20 has opposite first and second sides, and the line connecting the first and second sides forms an angle with the conveying direction of the conveying device 20; A plurality of side pushing devices 30 are arranged on the first side and / or the second side. The side pushing devices 30 on the first side and / or the side pushing devices 30 on the second side are arranged along the conveying direction, and the side pushing devices 30 on the first side and / or the side pushing devices 30 on the second side can be independently actuated.

[0028] In this embodiment, by arranging a plurality of side pushing devices 30 on the first side and the second side of the conveying device 20, the side pushing devices 30 are respectively directed to different positions on the side of the bulk bag, and the plurality of side pushing devices 30 can act independently, so that the side pushing devices 30 can push the bulk bag at different parts on the side of the bulk bag in a targeted manner, making the centering process of the bulk bag more accurate, thus realizing the precise alignment of the bulk bag. This setting method can quickly adjust the position of the bulk bag, with high accuracy, high efficiency, and high degree of automation, enabling the bulk bag conveying system to be more widely applied in fields such as manufacturing and medical treatment.

[0029] It should be noted that the base 10 of this embodiment includes the bottom bracket of the conveying device 20, the bottom bracket of the side pushing device 30, the bottom bracket of the front pushing device 50, the bottom bracket of the rear pushing device 60, and the bottom bracket of the lifting device 80. Each base bracket can be integrally arranged or separately arranged. In this embodiment, taking the separate arrangement as an example, the conveying device 20, the side pushing device 30, the front pushing device 50, the rear pushing device 60, and the lifting device 80 are respectively provided with bottom brackets at the bottom, and each bottom bracket together forms the base 10.

[0030] Such as Figure 3As shown, in this embodiment, the side pushing device 30 includes a side pushing baffle 31 and a side pushing driving member 32. The side pushing baffle 31 is movably arranged transversely relative to the base 10. The side pushing driving member 32 is drivingly connected to the side pushing baffle 31 and can drive the side pushing baffle 31 of the side pushing device 30 on the first side to move towards the second side and drive the side pushing baffle 31 of the side pushing device 30 on the second side to move towards the first side to center the bulk bag. In this way, when the bulk bag deviates from the center of the conveying device 20 and is biased towards the first side, the side pushing baffle 31 on the first side pushes the bulk bag to move towards the second side. When the bulk bag deviates from the center of the conveying device 20 and is biased towards the second side, the side pushing baffle 31 on the second side pushes the bulk bag to move towards the first side. When the bulk bag tilts towards the first side, the side pushing baffle 31 closest to the bulk bag on the first side pushes the bulk bag to move the bulk bag towards the center of the conveying device 20. When the bulk bag tilts towards the second side, the side pushing baffle 31 closest to the bulk bag on the second side pushes the bulk bag to move the bulk bag towards the center of the conveying device 20, thus achieving precise adjustment of the position of the bulk bag. Specifically, in this embodiment, a plurality of side pushing devices 30 are provided on both the first side and the second side of the conveying device 20. In this embodiment, it is described by taking three side pushing devices 30 provided on both the first side and the second side as an example. The side pushing baffle 31 is arranged in a plate-like structure, which can be a rectangular plate-like structure, a pentagonal plate-like structure or a plate-like structure with an irregular shape, etc. One side of the side pushing baffle 31 faces the side of the bulk bag, and the other side of the side pushing baffle 31 is connected to the side pushing driving member 32. In this way, the side pushing driving member 32 can drive the side pushing baffle 31 and drive the bulk bag to move. Specifically, the corresponding side pushing device 30 can be enabled according to the tilting direction of the bulk bag. When the side of the bulk bag close to the starting end of the conveying device 20 tilts towards the first side, the corresponding side pushing device 30, that is, the side pushing device 30 on the first side close to the starting end of the conveying device 20, is enabled, and the side pushing baffle 31 pushes the part of the bulk bag tilting towards the first side to move towards the center of the conveying device 20. When the side of the bulk bag far from the starting end of the conveying device 20 tilts, the corresponding side pushing device 30 is also enabled. This setting method realizes targeted adjustment for different tilting conditions of the bulk bag, thereby realizing rapid adjustment of the position of the bulk bag. Preferably, the side pushing baffles 31 on the first side and the second side are arranged opposite to each other, and the moving direction of the side pushing baffle 31 is perpendicular to the conveying direction of the bulk bag to further improve work efficiency. It should be noted that the side pushing baffles 31 in this embodiment do not affect each other, and the driving states of the side pushing driving members 32 are completely independent, and they can also work in any combination under the control of the bulk bag conveying system.

[0031] In this embodiment, the side pushing device 30 further includes a guiding member 33. The guiding member 33 is connected to the side pushing baffle 31 and moves synchronously with the side pushing baffle 31. The guiding member 33 is disposed through the base 10 to control the moving direction of the side pushing baffle 31. Specifically, along the arrangement direction of the side pushing baffle 31, the base 10 has a rectangular mounting plate. The side pushing baffle 31 is disposed on the side of the mounting plate close to the ton bag. The guiding member 33 and the side pushing driving member 32 are disposed through the side of the mounting plate away from the ton bag and are connected to the side pushing baffle 31. The guiding member 33 is set to be cylindrical and is disposed perpendicular to the conveying direction of the ton bag. One guiding member 33 is disposed on each side of each side pushing driving member 32, so as to improve the stability of the extension and retraction of the side pushing baffle 31.

[0032] As Figure 3 shown, in this embodiment, the ton bag conveying system further includes a detecting member 40 for detecting the position of the ton bag. The detecting member 40 is connected to the base 10. The detecting member 40 is located on the first side and / or the second side, and the detecting member 40 is closer to the starting end of the conveying device 20 than the side pushing device 30, that is, the ton bag first passes through the detecting member 40 to detect the inclination degree, and then is conveyed to the side pushing device 30 by the conveying device 20 to adjust the position of the ton bag. The detecting member 40 is electrically connected to the side pushing device 30 and controls the actions of each side pushing device 30 according to the detection result. In this way, when the ton bag passes through the transportation device, the detecting member 40 scans the shape of the ton bag, detects the inclination degree of the ton bag, and feeds back the detection result, so that the ton bag conveying system can accurately activate the side pushing device 30 at the corresponding position, thereby quickly adjusting the position of the ton bag. Moreover, the whole process does not require manual participation, saving time and effort, and improving the automation degree of ton bag position adjustment. Optionally, the detecting member 40 can be set as a distance sensor or the like.

[0033] In this embodiment, there are multiple detecting members 40, and the detecting members 40 are disposed on both the first side and the second side. The detecting members 40 on the first side and the detecting members 40 on the second side are symmetrically disposed along the center line of the conveying device 20. In this way, when the ton bag passes through the detecting member 40, the detecting members 40 on both sides can simultaneously detect the inclination degrees of the ton bag positions on the first side and the second side, so as to more accurately judge the displacement deviation degree of the ton bag, and further enable the ton bag conveying system to more accurately control the actions of the side pushing device 30 at the corresponding position, thereby improving the efficiency of ton bag alignment adjustment. Of course, according to actual needs, the detecting member 40 can also be disposed only on the first side or the second side, and the inclination degree of the ton bag on the other side can be inferred from the information obtained from the detecting member 40 on one side.

[0034] As Figure 4As shown, in this embodiment, the bulk bag conveying system further includes a front pushing device 50, a rear pushing device 60, and a shielding device 70. The front pushing device 50 and the rear pushing device 60 are respectively located on both sides of the conveying device 20 along the conveying direction, and the pushing force directions of the front pushing device 50 and the rear pushing device 60 are opposite. The front pushing device 50 and the rear pushing device 60 perform position adjustment in the conveying direction to prevent the bulk bag from being too far forward or to reset other components. The shielding device 70 is connected to the base 10 and is arranged outside the front pushing device 50 and / or the rear pushing device 60 to shield the front pushing device 50 and / or the rear pushing device 60. In this embodiment, as Figure 1 shown, shielding devices 70 are provided for both the front pushing device 50 and the rear pushing device 60. In this way, the shielding device 70 isolates the internal structures of the front pushing device 50 and / or the rear pushing device 60 from the bulk bag, thereby avoiding possible contamination during the bulk bag conveying process and the working process, and at the same time protecting the internal structures of the front pushing device 50 and / or the rear pushing device 60 from being damaged due to accidental bumps, making the bulk bag conveying system safer and more reliable.

[0035] As Figure 1 shown, in this embodiment, the shielding device 70 includes a shielding cover, which is located above the front pushing device 50 and / or the rear pushing device 60 and shields the upper regions of the front pushing device 50 and / or the rear pushing device 60. Specifically, shielding covers are provided above both the front pushing device 50 and the rear pushing device 60 in this embodiment. The shielding covers match the sizes of the front pushing device 50 and the rear pushing device 60 to cover the upper components thereof, thereby cooperating with the base 10 below to cover the internal structures of the front pushing device 50 and the rear pushing device 60, ensuring the cleanliness of the bulk bag materials and the safety of the front pushing device 50 and the rear pushing device 60 at the same time.

[0036] In this embodiment, the bulk bag conveying system further includes a lifting device 80. The lifting device 80 is liftably arranged inside the conveying device 20 and can rise upward from inside the conveying device 20 to drive the bulk bag to rise. In this way, when the bulk bag is conveyed above the lifting device 80, the lifting device 80 rises, lifts the bulk bag to a set height, and then adjusts the position of the bulk bag through the side pushing device 30 and the front pushing device 50. As Figure 1 shown, the lifting device 80 is arranged below the conveying device 20. When the lifting device 80 rises, it rises from below the conveying device 20 to above the conveying device 20, so as to be able to lift the bulk bag to adjust the height of the bulk bag.

[0037] As Figure 5As shown, in this embodiment, the jacking device 80 includes a jacking push plate 81 and a jacking driving member 82. The jacking push plate 81 is movably arranged with the base 10. The jacking push plate 81 can lift and drive the bulk bag to lift. When the jacking push plate 81 rises, the jacking push plate 81 is located on the pushing path of the rear pushing device 60, and the rear pushing device 60 can push the jacking push plate 81 to move. In this way, when the bulk bag is conveyed onto the jacking push plate 81, the jacking push plate 81 rises to drive the bulk bag to rise. The side pushing device 30 and the front pushing device 50 adjust the position of the bulk bag. When adjusting the position of the bulk bag, the position of the jacking push plate 81 moves accordingly. After the bulk bag is taken away, the rear pushing device 60 and the front pushing device 50 push the side pushing baffle 31 to reset it. The jacking driving member 82 is arranged below the jacking push plate 81, that is, inside the base 10, and a direction ball bearing mounting seat is connected above the jacking driving member 82. The jacking push plate 81 is stacked above the direction ball bearing mounting seat. The jacking driving member 82 can drive the direction ball bearing mounting seat to lift, so as to drive the jacking push plate 81 to lift. The jacking push plate 81 of this embodiment is set as a horizontally placed rectangular plate-like structure to match the shape of the bulk bag and facilitate placing the bulk bag. It should be noted that the front pushing device 50 can not only push the bulk bag, but also push the jacking push plate 81, and the actions of pushing the bulk bag and pushing the jacking push plate 81 are carried out separately without interference. That is to say, the front pushing device 50 is provided with a first front pushing baffle for pushing the bulk bag to adjust the position of the bulk bag and a second front pushing baffle for pushing the jacking push plate 81 to reset the jacking push plate 81.

[0038] In this embodiment, the bulk bag conveying system further includes a deceleration signal detector and an in-place signal detector. The deceleration signal detector is located on the first side and / or the second side; the in-place signal detector is located on the first side and / or the second side, and the deceleration signal detector is closer to the starting end of the conveying device 20 than the in-place signal detector. Both the deceleration signal detector and the in-place signal detector are electrically connected to the conveying device 20 and control the conveying action of the conveying device 20 according to the detection results. In this way, the bulk bag first passes through the deceleration signal detector. After the deceleration signal detector detects the arrival of the bulk bag, it outputs a deceleration signal to the conveying device 20, and the conveying device 20 starts to decelerate; when the bulk bag is conveyed to the in-place signal detector, after the in-place signal detector detects the in-place of the bulk bag, it outputs an in-place signal to the conveying device 20, and the conveying device 20 stops conveying, thus ensuring the automatic control of the bulk bag conveying process.

[0039] The overall process steps of the bulk bag conveying system in this embodiment are as follows: In the initial state, the bulk bag is located at the starting end of the conveying device 20 and starts to be conveyed. At this time, the detection components 40 on the first side and the second side start to work. By scanning the shape of the bulk bag, the position offset of the bulk bag is judged; the detection component 40 feeds back the offset situation of the bulk bag to the side pushing device 30; the bulk bag reaches the deceleration signal detector along the conveying device 20, and the conveying device 20 starts to decelerate; when the bulk bag reaches the in-place signal detector, the conveying device 20 stops conveying; the lifting device 80 rises and raises the bulk bag to the set height; the side pushing device 30 controls the movement of the side pushing baffles 31 on the first side and the second side according to the offset situation of the bulk bag. By means of combination forms such as clamping on both sides or pushing by a single side pushing baffle 31, it is ensured that the bulk bag does not offset in the horizontal direction; the forward pushing device 50 pushes the bulk bag to a suitable position to prevent the bulk bag from being too far forward. Since a directional ball bearing mounting seat is provided below the lifting push plate 81, the lifting push plate 81 and the bulk bag will move along with the pushing of the side pushing baffle 31, and the situation that the bulk bag is too far forward may occur. Here, being too far forward refers to the side far from the starting end of the conveying device 20; the bulk bag enters the bag breaking chamber and enters the bag breaking stage; the forward pushing device 50 and the backward pushing device 60 retract the lifting push plate 81 to the initial position; the lifting device 80 descends back to the initial position.

[0040] It should be noted that the multiple in the above embodiments refers to at least two.

[0041] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0042] 1. Solve the problem of poor accuracy of the position of the bulk bag in the prior art;

[0043] 2. Enable the side pushing device to push the bulk bag at different parts on the side of the bulk bag in a targeted manner, so that the centering process of the bulk bag is more accurate, thereby realizing the precise alignment of the bulk bag;
