Description

Technical Field

[0001] The present disclosure relates to the technical field of packaging bag detection-related mechanisms, and in particular to a bag stacking detection structure and a packaging bag conveying device. Background Art

[0002] A bag conveyor is an industrial device used to transport bags from a loading location to a predetermined location. It is widely used in large warehouses, material distribution centers, and for packaging food, agricultural products, medical supplies, and electronics.

[0003] In the related art, the packaging bag conveying device includes a conveying line body, a bag picking mechanism and a bag stacking detection structure. The bag picking mechanism is arranged adjacent to the bag stacking detection structure, and the bag picking mechanism and the bag stacking detection structure are both connected to the conveying line body; the bag picking mechanism is used to absorb the packaging bags to move the packaging bags to the conveying line body to complete the loading process. The conveying line body is used to transport the packaging bags to the bottom of the bag stacking detection structure. The bag stacking detection structure includes a connected structural body and a displacement sensor. The structural body is connected to the conveying line body. The displacement sensor is used to detect the bag thickness of the packaging bag (that is, the thickness of the packaging bag) and to determine whether there is a bag stacking problem with the packaging bags (that is, whether two packaging bags are stuck together and overlapped, or whether multiple packaging bags are stuck together and overlapped).

[0004] Since the thickness of the packaging bag is 0.1mm, the thickness of the two overlapping packaging bags is 0.2mm, that is, when the two packaging bags overlap, there is a thickness difference of 0.1mm, so that the displacement size change of the displacement sensor when detecting the thickness of the packaging bag is small, making it easier for the bag overlap detection structure to misjudge the thickness of the packaging bag, resulting in low accuracy in the detection of the bag overlap detection structure.

The bag taking mechanism is arranged adjacent to the bag stacking detection structure, and both the bag taking mechanism and the bag stacking detection structure are connected to the conveying line.

[0022] Compared with the prior art, the present disclosure has at least the following advantages:

[0023] 1. Since the driving assembly is used to drive the connecting plate body to press downward, so that the detection touch rod is used to press against the packaging bag, the detection touch rod is slidably connected to the connecting plate body, so that the detection touch rod slides upward relative to the connecting plate body under the reaction force of the packaging bag, and the connecting rod body is rotatably connected to the connecting plate body, so that the connecting rod body is a lever structure, one end of the connecting rod body is movably connected to the displacement guide rod, and the other end of the connecting rod body is movably connected to the detection touch rod, so that the detection touch rod drives one end of the connecting rod body to rotate upward, and the other end of the connecting rod body rotates downward under the action of the force, and the displacement guide rod is slidably connected to the connecting plate body, so that one end of the connecting rod body drives the displacement guide rod to slide downward relative to the connecting plate body, and the spacing sensor is used to detect the sliding displacement of the displacement guide rod, that is, the spacing sensor is used to detect the downward sliding displacement of the displacement guide rod, thereby completing the bag stacking detection process of the packaging bag;

[0024] 2. When the bag thickness is 0.1mm, the detection feeler slides upward by 0.1mm relative to the connecting plate, causing one end of the connecting rod to rotate upward by 0.1mm. When the second distance is equal to 0.5 times the first distance, that is, the first distance is twice the second distance, the other end of the connecting rod rotates downward by 0.2mm according to the lever principle, causing the displacement guide rod to slide downward by 0.2mm relative to the connecting plate.

The terms used herein in the specification of this disclosure are intended only to describe specific embodiments and are not intended to limit this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] The present disclosure provides a bag stacking detection structure, comprising a machine base, a drive assembly, a detection feeler rod, a slide assembly, and a spacing sensor; the drive assembly is mounted on the machine base; the detection feeler rod is used to press against the packaging bag; the slide assembly comprises a connecting plate body, a displacement guide rod, and a connecting rod body, wherein the displacement guide rod and the detection feeler rod are both slidably connected to the connecting plate body; the connecting rod body is rotatably connected to the connecting plate body, one end of the connecting rod body is movably connected to the displacement guide rod, and the other end of the connecting rod body is movably connected to the detection feeler rod; the position where the connecting rod body is connected to the connecting plate body is a first connection position, the position where the connecting rod body is connected to the displacement guide rod is a second connection position, and the position where the connecting rod body is connected to the detection feeler rod is a third connection position, the distance between the second connection position and the first connection position is a first distance, the distance between the third connection position and the first connection position is a second distance, and the second distance is less than or equal to 0.5 times the first distance; a power output end of the drive assembly is connected to the connecting plate body, and the drive assembly is used to drive the connecting plate body to move relative to the machine base; the spacing sensor is mounted on the connecting plate body, the spacing sensor is arranged opposite to the displacement guide rod, and the spacing sensor is used to detect the sliding displacement of the displacement guide rod.

[0038] The above-mentioned bag stacking detection structure, since the driving assembly is used to drive the connecting plate body to press down, so that the detection feeling rod is used to press the packaging bag, the detection feeling rod is slidably connected to the connecting plate body, so that the detection feeling rod is subjected to the reaction force of the packaging bag and slides upward relative to the connecting plate body, and the connecting rod body is rotatably connected to the connecting plate body, so that the connecting rod body is a lever structure, one end of the connecting rod body is movably connected to the displacement guide rod, and the other end of the connecting rod body is movably connected to the detection feeling rod, so that the detection feeling rod drives one end of the connecting rod body to rotate upward, and the other end of the connecting rod body rotates downward under the action of the force, and the displacement guide rod is slidably connected to the connecting plate body, so that one end of the connecting rod body drives the displacement guide rod to slide downward relative to the connecting plate body, and the spacing sensor is used to detect the sliding displacement of the displacement guide rod, that is, the spacing sensor is used to detect the downward sliding displacement of the displacement guide rod, thereby completing the bag stacking detection process of the packaging bag;

[0039] When the bag thickness is 0.1mm, the detection feeler slides upward by 0.1mm relative to the connecting plate, causing one end of the connecting rod to rotate upward by 0.1mm. When the second distance is equal to 0.5 times the first distance, that is, the first distance is twice the second distance, according to the lever principle, the other end of the connecting rod rotates downward by 0.2mm, causing the displacement guide rod to slide downward by 0.2mm relative to the connecting plate. The distance sensor is used to detect the 0.2mm downward displacement of the displacement guide rod, thereby effectively amplifying the detection size of the bag thickness.

[0040] Similarly, when two packaging bags are adhered and overlapped, the thickness of the packaging bags is 0.2mm. The slide assembly and the detection feeler rod jointly amplify the detection size of the packaging bag thickness, so that the spacing sensor is used to detect the displacement of the displacement guide rod sliding downward is 0.4mm, so that the displacement of the displacement guide rod sliding downward can be better used to judge whether there is a bag overlap problem in the packaging bags; that is, when two packaging bags overlap, the detection size of the bag thickness is amplified by the slide assembly and the detection feeler rod, so that there is an amplified thickness difference of 0.2mm in the bag thickness, so that the displacement size of the spacing sensor changes greatly when detecting the displacement of the displacement guide rod sliding downward, thereby making it less likely for the bag overlap detection structure to make a misjudgment when detecting the bag thickness, and thus making the bag overlap detection structure have a higher accuracy in detecting the bag thickness.

[0041] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0042] like Figures 1 to 6As shown, a bag stacking detection structure 10a of an embodiment includes a machine base 100, a driving assembly 200, a detection feeler rod 500, a slide assembly 300 and a spacing sensor 400; the driving assembly 200 is installed on the machine base 100; the detection feeler rod 500 is used to press against the packaging bag; the slide assembly 300 includes a connecting plate body 310, a displacement guide rod 320 and a connecting rod body 330, and the displacement guide rod 320 and the detection feeler rod 500 are both slidably connected to the connecting plate body 310; the connecting rod body 330 is rotatably connected to the connecting plate body 310, one end of the connecting rod body 330 is movably connected to the displacement guide rod 320, and the other end of the connecting rod body 330 is movably connected to the detection feeler rod 500; the position where the connecting rod body 330 is connected to the connecting plate body 310 is a first connection position The position where the connecting rod body 330 is connected to the displacement guide rod 320 is the second connection position, the position where the connecting rod body 330 is connected to the detection touch rod 500 is the third connection position, the distance between the second connection position and the first connection position is the first distance L1, the distance between the third connection position and the first connection position is the second distance L2, and the second distance L2 is less than or equal to 0.5 times the first distance L1; the power output end of the driving component 200 is connected to the connecting plate body 310, and the driving component 200 is used to drive the connecting plate body 310 to move relative to the machine base 100; the distance sensor 400 is installed on the connecting plate body 310, and the distance sensor 400 is arranged opposite to the displacement guide rod 320, and the distance sensor 400 is used to detect the sliding displacement of the displacement guide rod 320.

[0043] In this embodiment, the drive assembly 200 is used to drive the connecting plate 310 to move relative to the base 100, that is, the drive assembly 200 is used to drive the connecting plate 310 to rise or lower relative to the base 100. The connecting rod 330 is rotatably connected to the connecting plate 310, so that the connecting rod 330 forms a lever structure. The spacing sensor 400 is used to detect the sliding displacement of the displacement guide rod 320, that is, the spacing sensor 400 is used to detect the downward sliding displacement of the displacement guide rod 320.

[0044] In the bag stacking detection structure 10a, the driving assembly 200 is used to drive the connecting plate 310 to press down, so that the detection feeler rod 500 is used to press against the packaging bag. The detection feeler rod 500 is slidably connected to the connecting plate 310, so that the detection feeler rod 500 is subjected to the reaction force of the packaging bag and slides upward relative to the connecting plate 310. The connecting rod 330 is rotatably connected to the connecting plate 310, so that the connecting rod 330 is a lever structure. One end of the connecting rod 330 is movably connected to the displacement guide rod 320, and the other end of the connecting rod 330 is movably connected to the detection guide rod 320. The sensing rod 500 is movably connected, so that the sensing rod 500 drives one end of the connecting rod body 330 to rotate upward, and the other end of the connecting rod body 330 rotates downward under the action of force. The displacement guide rod 320 is slidably connected to the connecting plate body 310, so that one end of the connecting rod body 330 drives the displacement guide rod 320 to slide downward relative to the connecting plate body 310. The spacing sensor 400 is used to detect the sliding displacement of the displacement guide rod 320, that is, the spacing sensor 400 is used to detect the downward sliding displacement of the displacement guide rod 320, thereby completing the bag stacking detection process;

[0045] When the bag thickness is 0.1 mm, the detection feeler 500 slides upward by 0.1 mm relative to the connecting plate 310, causing one end of the connecting rod 330 to rotate upward by 0.1 mm. When the second distance L2 is equal to 0.5 times the first distance L1, that is, the first distance L1 is twice the second distance L2, the other end of the connecting rod 330 rotates downward by 0.2 mm according to the lever principle, causing the displacement guide rod 320 to slide downward by 0.2 mm relative to the connecting plate 310. The distance sensor 400 is used to detect the 0.2 mm downward displacement of the displacement guide rod 320, thereby effectively amplifying the detection size of the bag thickness.

[0046] Similarly, when two packaging bags are adhered and overlapped, the thickness of the packaging bags is 0.2 mm. The slide assembly 300 and the detection feeler rod 500 jointly amplify the detection size of the packaging bag thickness, so that the spacing sensor 400 is used to detect the displacement of the displacement guide rod 320 sliding downwards, which is 0.4 mm, so that the displacement of the displacement guide rod 320 sliding downwards can be better used to judge whether there is a bag overlap problem in the packaging bags; that is, when two packaging bags overlap, the detection size of the bag thickness is amplified by the joint action of the slide assembly 300 and the detection feeler rod 500, so that there is an amplified thickness difference of 0.2 mm in the bag thickness, so that the displacement size of the spacing sensor 400 changes greatly when detecting the displacement of the displacement guide rod 320 sliding downwards, thereby making it less likely for the bag overlap detection structure 10a to make a misjudgment when detecting the bag thickness, and thereby making the bag overlap detection structure 10a have a higher accuracy in detecting the bag thickness.

[0047] Furthermore, when multiple packaging bags are adhered and overlapped together, that is, when three packaging bags are adhered and overlapped together, the thickness of the packaging bags is 0.3 mm. The slide assembly 300 and the detection feeler 500 jointly amplify the detection size of the packaging bag thickness, so that the spacing sensor 400 is used to detect the displacement of the displacement guide rod 320 sliding downward is 0.6 mm, so that the displacement of the displacement guide rod 320 sliding downward can be better used to judge whether there is a bag overlap problem in the packaging bags; that is, when the three packaging bags overlap, the detection size of the bag thickness is amplified by the joint action of the slide assembly 300 and the detection feeler 500, so that there is an amplified thickness difference of 0.3 mm in the bag thickness, so that the displacement size of the spacing sensor 400 when detecting the displacement of the displacement guide rod 320 sliding downward changes greatly, so that the bag overlap detection structure 10a is less likely to make a misjudgment when detecting the bag thickness, thereby improving the detection accuracy of the bag overlap detection structure 10a for the bag thickness of the packaging bags.

[0048] like Figures 1 to 5 As shown, in one embodiment, the base 100 includes a fixed base body 110 and a mounting plate body 120 connected to each other, and the drive assembly 200 is mounted on the mounting plate body 120. In this embodiment, the fixed base body 110 and the mounting plate body 120 are welded, so that the connection between the fixed base body 110 and the mounting plate body 120 is more stable, thereby improving the structural stability of the base 100.

[0049] like Figure 1 As shown, in one embodiment, the fixed seat body 110 is provided with a sliding rail portion 111, and the connecting plate body 310 is provided with a sliding portion 311. The sliding portion 311 is provided with a sliding groove 3111. The sliding rail portion 111 is passed through the sliding groove 3111 and is slidably connected to the sliding portion 311, so that the connecting plate body 310 slides relative to the fixed seat body 110, thereby effectively improving the movement convenience of the connecting plate body 310.

[0050] like Figure 1 As shown, in one embodiment, the connecting plate 310 is provided with a first mounting portion 312 , and the distance sensor 400 is mounted on the first mounting portion 312 , so that the position stability of the distance sensor 400 is better.

[0051] like Figures 1 to 2 As shown, in one embodiment, the connecting plate 310 is further provided with a second mounting portion 313. The first mounting portion 312 and the second mounting portion 313 are arranged opposite each other. The second mounting portion 313 defines a first sliding hole 3131. The displacement guide rod 320 is inserted through the first sliding hole 3131 and is slidably connected to the second mounting portion 313. In this embodiment, the distance sensor 400 is located directly above the displacement guide rod 320, so that the distance sensor 400 can detect the sliding displacement of the displacement guide rod 320 with high accuracy.

[0052] like Figures 1 to 4 As shown, in one embodiment, the connecting plate body 310 is provided with an avoidance groove (not shown in the figure), and the inner wall of the avoidance groove is provided with a first rotation hole 3141 and a second rotation hole 3142, the first rotation hole 3141 and the second rotation hole 3142 are arranged opposite to each other, and the connecting rod body 330 is provided with a rotating shaft body 331, one end of the rotating shaft body 331 is passed through the first rotation hole 3141 and is rotatably connected to the connecting plate body 310, and the other end of the rotating shaft body 331 is passed through the second rotation hole 3142 and is rotatably connected to the connecting plate body 310, so that the connecting rod body 330 rotates relative to the connecting plate body 310; the position where the rotating shaft body 331 is connected to the connecting plate body 310 is the first connection position. In this embodiment, the connecting rod body 330 and the rotating shaft body 331 together constitute a lever structure, the distance between the second connection position and the first connection position is a first distance L1, and the distance between the third connection position and the first connection position is a second distance L2. The second distance L2 is less than or equal to 0.5 times the first distance L1, thereby effectively enlarging the detection size of the bag thickness of the packaging bag and improving the detection accuracy of the bag stacking detection structure 10a for the bag thickness of the packaging bag.

[0053] like Figures 1 to 4 As shown, in one embodiment, the connecting plate body 310 is provided with a third mounting portion 315, and the third mounting portion 315 is provided with a second sliding through hole 3151. The detection sensing rod 500 is passed through the second sliding through hole 3151 and is slidably connected to the third mounting portion 315. The third mounting portion 315 plays a better limiting role on the detection sensing rod 500 to ensure that the detection sensing rod 500 slides upward along the vertical direction of the connecting plate body 310, thereby improving the detection accuracy of the bag stacking detection structure 10a on the bag thickness of the packaging bag.

[0054] In one embodiment, the driving assembly 200 is a driving cylinder or a driving motor, so that the bag stacking detection structure 10a meets automation requirements.

[0055] In one embodiment, the detection sensing rod 500 is an integrally formed structure, so that the structural strength of the detection sensing rod 500 is high.

[0056] Further, if Figures 1 to 6 As shown, in one embodiment, the detection feeler rod 500 includes a connecting portion 510 and a detecting portion 520. The connecting portion 510 is connected to the detecting portion 520. The detecting portion 520 is disposed in the second sliding through hole 3151 and is slidably connected to the third mounting portion 315. The connecting portion 510 abuts the third mounting portion 315 and is movably connected to the end of the connecting rod body 330 that is away from the displacement guide rod 320. In this embodiment, the connecting portion 510 and the detecting portion 520 are integrally formed, which provides a high structural strength between the connecting portion 510 and the detecting portion 520.

[0057] Furthermore, in one embodiment, the detection portion 520 is provided with a weight-reducing groove 521 to reduce the weight of the detection portion 520, thereby reducing the weight of the detection sensing rod 500, so that the detection sensing rod 500 can slide upward more easily relative to the connecting plate body 310 under the reaction force of the packaging bag, thereby making the bag stacking detection mechanism more sensitive to the packaging bag.

[0058] Furthermore, in one embodiment, the outer diameter of the connecting portion 510 is larger than the aperture of the second sliding through hole 3151, so that the connecting portion 510 is abutted against a side surface of the third mounting portion 315, so that the third mounting portion 315 plays a better limiting role, thereby effectively limiting the downward sliding displacement of the detection feeler rod 500. That is, the detection feeler rod 500 meets the requirement of a small displacement, making the detection feeler rod 500 more convenient to use.

[0059] Furthermore, in one embodiment, the connecting plate body 310 is provided with a fourth mounting portion 316, the fourth mounting portion 316 is arranged opposite to the connecting portion 510, the fourth mounting portion 316 is provided with a first connecting hole (not shown), and the connecting portion 510 is provided with a second connecting hole 511. The bag stacking detection structure 10a also includes a first elastic element 600, one end of the first elastic element 600 is passed through the first connecting hole and is elastically connected to the fourth mounting portion 316, and the other end of the first elastic element 600 is passed through the second connecting hole 511 and is elastically connected to the connecting portion 510.

[0066] Furthermore, in one embodiment, the two detection sensing rods 500 are symmetrically distributed about the central axis of the connecting plate 310 , thereby increasing the structural balance of the slide assembly 300 and improving the structural stability of the bag stacking detection structure 10 a .

[0067] like Figure 7 As shown, the present disclosure also provides a packaging bag conveying device 10, including a conveying line body 20a, a bag picking mechanism 30a and a bag stacking detection structure 10a of any of the above embodiments, the bag picking mechanism 30a is arranged adjacent to the bag stacking detection structure 10a, and the bag picking mechanism 30a and the bag stacking detection structure 10a are both connected to the conveying line body 20a.

[0068] In this embodiment, the base 100 is connected to the conveying line 20a, so that the conveying line 20a is used to convey the packaging bag to the position directly below the detection sensing rod 500. Furthermore, the fixed base 110 is connected to the conveying line 20a.

[0069] In one embodiment, the conveyor line 20a is provided with multiple pallets 800, which are spaced apart. The conveyor line 20a is used to drive the movement of each pallet 800, and each pallet 800 is used to support the packaging bag. In this embodiment, when the detection sensing rod 500 is used to press against the packaging bag, each pallet 800 is used to support the packaging bag, so that each pallet 800 is closely fitted to the packaging bag, thereby preventing the packaging bag from sinking under the action of the detection sensing rod 500. This makes it less likely that the bag stacking detection structure 10a will misjudge the bag thickness when detecting the packaging bag, thereby achieving a higher accuracy in the bag stacking detection structure 10a's detection of the packaging bag thickness.

[0070] Furthermore, in one embodiment, the conveyor line body 20a is also provided with a positioning mechanism (not shown), which is used to position each pallet body 800 so that each pallet body 800 is precisely positioned directly below the detection sensing rod 500, that is, the packaging bag is precisely positioned directly below the detection sensing rod 500, so that the bag stacking detection structure 10a is more convenient for detecting the thickness of the packaging bag.

[0071] Compared with the prior art, the present disclosure has at least the following advantages:

[0072] 1. Since the driving assembly 200 is used to drive the connecting plate 310 to press downward, so that the detection feeler rod 500 is used to press against the packaging bag, the detection feeler rod 500 is slidably connected to the connecting plate 310, so that the detection feeler rod 500 is subjected to the reaction force of the packaging bag and slides upward relative to the connecting plate 310, the connecting rod 330 is rotatably connected to the connecting plate 310, so that the connecting rod 330 is a lever structure, one end of the connecting rod 330 is movably connected to the displacement guide rod 320, and the other end of the connecting rod 330 is movably connected to the detection feeler rod 500. The movable connection enables the detection feeler rod 500 to drive one end of the connecting rod body 330 to rotate upward, and the other end of the connecting rod body 330 to rotate downward under the action of force. The displacement guide rod 320 is slidably connected to the connecting plate body 310, so that one end of the connecting rod body 330 drives the displacement guide rod 320 to slide downward relative to the connecting plate body 310. The spacing sensor 400 is used to detect the sliding displacement of the displacement guide rod 320, that is, the spacing sensor 400 is used to detect the downward sliding displacement of the displacement guide rod 320, thereby completing the bag stacking detection process;

[0073] 2. When the bag thickness is 0.1 mm, the detection feeler 500 slides upward 0.1 mm relative to the connecting plate 310, causing one end of the connecting rod 330 to rotate upward 0.1 mm. When the second distance L2 is equal to 0.5 times the first distance L1 (i.e., the first distance L1 is twice the second distance L2), the lever principle causes the other end of the connecting rod 330 to rotate downward 0.2 mm, causing the displacement guide rod 320 to slide downward 0.2 mm relative to the connecting plate 310. The spacing sensor 400 detects the 0.2 mm downward displacement of the displacement guide rod 320, thereby effectively amplifying the detection range of the bag thickness.

[0074] 3. Similarly, when two packaging bags are adhered and overlapped, the thickness of the packaging bags is 0.2 mm. The sliding plate assembly 300 and the detection feeler rod 500 jointly amplify the detection size of the packaging bag thickness, so that the distance sensor 400 is used to detect the displacement of the displacement guide rod 320 sliding downwards of 0.4 mm, so that the displacement of the displacement guide rod 320 sliding downwards can be better used to determine whether there is a bag overlap problem. That is, when two packaging bags overlap, the detection size of the bag thickness is amplified by the sliding plate assembly 300 and the detection feeler rod 500, so that there is an amplified thickness difference of 0.2 mm in the bag thickness, so that the displacement size of the spacing sensor 400 when detecting the displacement of the displacement guide rod 320 sliding downwards changes greatly, thereby making it less likely for the bag overlap detection structure 10a to make a misjudgment when detecting the bag thickness, thereby making the bag overlap detection structure 10a have a higher accuracy in detecting the bag thickness.
