Description

Technical Field

[0001] This utility model relates to the field of automated equipment, and in particular to a box flipping device. Background Technology

[0002] On existing product packaging lines, it is often necessary to flip the packaging boxes to a predetermined printing surface for related operations such as inkjet printing, printing, and orientation.

[0003] In small-scale production, boxes are typically flipped manually. However, manual flipping is time-consuming and labor-intensive, and unsuitable for large-scale production. Large-scale production generally requires a flipping device with multiple drive mechanisms. However, such devices are overly complex due to the need for multiple drive components, and also occupy a large area due to the numerous parts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a box flipping device that has high flipping efficiency, simple structure, and small footprint.

[0005] This utility model is achieved through the following technical solution:

[0006] A box flipping device for flipping packaging boxes, comprising:

[0007] A first conveyor belt, arranged horizontally, is configured to convey the packaging box;

[0008] The second conveyor belt is arranged parallel to the first conveyor belt and runs in the same direction. The horizontal height of the second conveyor belt is lower than that of the first conveyor belt, and the input end of the second conveyor belt is located close to the output end of the first conveyor belt.

[0009] In the vertical direction, the projection of the output end of the first conveyor belt onto the plane of the second conveyor belt is located inside the second conveyor belt, and the second running speed of the second conveyor belt is less than the first running speed of the first conveyor belt.

[0010] Furthermore, the height difference between the first conveyor belt and the second conveyor belt is greater than half the width of the box but less than the width of the box.

[0011] Furthermore, the drop height is two-thirds of the box width.

[0012] Furthermore, the first operating speed is 2 to 3 times the second operating speed.

[0013] Furthermore, the first operating speed is 2.5 times the second operating speed.

[0014] Furthermore, the box flipping device also includes a blocking mechanism, which includes at least one blocking strip disposed above the packaging box and configured to prevent the packaging box from flipping on the second conveyor belt.

[0015] Furthermore, the box flipping device also includes a first crossbar, which is arranged perpendicular to the running direction of the second conveyor belt, and the blocking bar includes a connecting part, which is rotatably sleeved on the first crossbar.

[0016] Furthermore, the blocking strip also includes a blocking part integrally formed with the connecting part, the blocking part being a curved strip with the bending direction opposite to the packaging box.

[0017] Furthermore, the blocking mechanism also includes a second crossbar, which is disposed above the blocking portion.

[0018] Furthermore, the second crossbar is arranged parallel to the first crossbar, and both are at the same horizontal height.

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] By using a first and a second conveyor belt, which have a height difference, a speed difference, and are arranged in parallel, the packaging box can be flipped 90° without the need for additional drive components. The structure is simple and reliable, occupies a small area, and is highly efficient. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] like Figures 1 to 3 As shown in the figure, an embodiment of this utility model provides a box flipping device for flipping a packaging box 4 from a horizontal state to a vertical state, so as to facilitate subsequent processes to perform related operations such as inkjet printing, printing, and orientation arrangement on a designated processing surface. In particular, the box flipping device provided by this utility model can achieve a 90° flip of the packaging box 4 without additional driving components by using the height and speed difference between two conveyor belts. It has a simple and reliable structure, occupies a small area, and has high efficiency.

[0027] Specifically, refer to Figure 1 and Figure 2The box-flipping device includes a first conveyor belt 1 and a second conveyor belt 2 arranged in parallel and running in the same direction. The first conveyor belt 1 is arranged horizontally and is used to transport the packaging box 4. The horizontal height of the second conveyor belt 2 is lower than that of the first conveyor belt 1, and the second running speed M2 of the second conveyor belt 2 is lower than the first running speed M1 of the first conveyor belt 1. When the packaging box 4 falls from the first conveyor belt 1, under the action of gravity and inertia, the packaging box 4 will assume a third posture t3, that is, the first side 40 of the packaging box 4 falls first and contacts the second conveyor belt 2. Since the second running speed M2 of the second conveyor belt 2 is lower than the first running speed M1 of the first conveyor belt 1, the packaging box 4 will continue to flip under the action of inertia and be transported on the second conveyor belt 2 with its first side 42 facing down, thus realizing the flipping of the packaging box 4. This utility model completes the flipping of the packaging box 4 while transporting it, which not only greatly improves the efficiency of the entire production line, but also hardly increases the footprint.

[0028] Furthermore, to ensure that the packaging box 4 does not fall off the production line during its journey from the first conveyor belt 1 to the second conveyor belt 2, the input end 20 of the second conveyor belt 2 is positioned close to the output end 10 of the first conveyor belt 1, and from a vertical perspective, the projection of the output end 10 of the first conveyor belt 1 onto the plane of the second conveyor belt 2 is located inside the second conveyor belt 2. That is, the first conveyor belt 1 at least partially overlaps with the second conveyor belt 2, thereby eliminating any gap between them and ensuring the stable drop of the packaging box 4.

[0029] Furthermore, in this embodiment, the second width d2 of the second conveyor belt 2 is consistent with the first width d1 of the first conveyor belt 1 to ensure that the packaging box 4 does not fall off the production line in the horizontal direction. It can be understood that the second width d2 of the second conveyor belt 2 can also be greater than the first width d1 of the first conveyor belt 1, as long as it is ensured that the second width d2 of the second conveyor belt 2 covers the first width d1 of the first conveyor belt 1 in the vertical direction.

[0030] Furthermore, the drop height H between the first conveyor belt 1 and the second conveyor belt 2 is greater than half the box width D and less than the box width D. This arrangement ensures that the flipping angle of the packaging box 4 will not exceed 90° during the process of falling from the first conveyor belt 1 to the second conveyor belt 2. Preferably, the drop height H is two-thirds of the box width D.

[0031] Furthermore, the first operating speed M1 of the first conveyor belt 1 is 2 to 3 times the second operating speed M2 of the second conveyor belt 2. This setting is to ensure that when the packaging box 4 falls onto the second conveyor belt 2, it can continue to rotate at a certain angle under the action of inertia, thereby ensuring that the packaging box 4 can rotate at least 90°. Preferably, the first operating speed M1 is 2.5 times the second operating speed M2.

[0032] Optionally, since the packaging box 4 will continue to rotate at a certain angle under the action of inertia after it falls onto the second conveyor belt 2, in order to prevent the rotation angle of the packaging box 4 from being greater than 90° and to ensure that the packaging box 4 can be conveyed on the second conveyor belt 2 in a 90° rotated posture (first side 42 facing down), the box rotation device also includes a blocking mechanism 3. The blocking mechanism 3 includes at least one blocking strip 30. The blocking strip 30 is set above the packaging box 4 and abuts against the second side 43 of the packaging box 4, which plays a certain guiding and stabilizing role for the packaging box 4 and prevents the packaging box 4 from rotating on the second conveyor belt 2.

[0033] Key reference Figure 3 The blocking mechanism 3 also includes a fixing structure 33 composed of two mutually perpendicular optical axes and a first crossbar 31 fixed to the fixing structure 33. The fixing structure 33 serves to fix the first crossbar 31 above the packaging box 4. The first crossbar 31 is set perpendicular to the running direction of the second conveyor belt 2, and the blocking strip 30 is at least partially rotatably fitted onto the first crossbar 31, that is, the blocking strip 30 extends along the direction of the second conveyor belt 2 to ensure that the packaging box 4 can remain stable during transportation and will not tip over.

[0034] Specifically, the blocking strip 30 includes a connecting part 301 and a blocking part 302 integrally formed with the connecting part 30. The connecting part 301 is rotatably sleeved on the first crossbar 31, so that the blocking part 302 can abut against the second surface 43 of the packaging box 4 under the action of gravity, so as to play a guiding role.

[0035] Furthermore, since the packaging box 4 will impact the blocking bar 30 when it is conveyed on the second conveyor belt 2, in order to prevent the blocking bar 30 from rotating counterclockwise around the first crossbar 31 under the impact and thus failing, the blocking mechanism 3 also includes a second crossbar 32. The second crossbar 32 is disposed above the blocking part 302 to provide a blocking effect. Preferably, the second crossbar 32 is arranged parallel to the first crossbar 31, and the two are at the same horizontal height.

[0036] Optionally, the aforementioned blocking portion 302 is a curved strip, with the curvature direction opposite to that of the packaging box 4. This allows the second surface 43 of the packaging box 4 to abut against the blocking portion 302 in the fourth state t4, thereby preventing the packaging box 4 from continuing to flip.

[0037] In this embodiment, two blocking strips 30 are provided. Of course, one or more can also be provided, as long as it is ensured that the blocking strips 30 do not generate excessive friction on the packaging box 4 during actual production line operation.

[0038] Optionally, the box flipping device provided in this application also includes a baffle 11 and a detection mechanism 5. The baffle 11 is disposed on both sides of the first conveyor belt 1 and is spaced apart from the packaging box 4 to prevent the packaging box 4 from falling in other postures and failing to flip over.

[0039] Furthermore, during normal operation, the packaging boxes 4 on the first conveyor belt 1 are horizontal and will only remain vertical after falling onto the second conveyor belt 2. However, sometimes due to equipment malfunctions in the previous process, the packaging boxes 4 on the first conveyor belt 1 may be vertical. In this case, falling onto the second conveyor belt 2 will knock over the normal packaging boxes 4. Therefore, the box flipping device is also equipped with a detection mechanism 5, which is set on the first conveyor belt 1 to detect and push away the packaging boxes 4 with incorrect posture.

[0040] Specifically, the detection mechanism 5 includes a recycling platform 50 and a push-out cylinder 51 arranged opposite each other on both sides of the first conveyor belt 1. A photoelectric sensor 52 is arranged next to the push-out cylinder 51. When the packaging box 4 on the first conveyor belt 1 passes the photoelectric sensor 52, it cannot be detected by the photoelectric sensor 52 due to its low posture. When the packaging box 4 is in a vertical posture, the photoelectric sensor 52 will activate the push-out cylinder 51 after detection, and the push-out cylinder 51 will push the unqualified packaging box 4 into the recycling platform 50.

[0041] Optionally, in this embodiment, the packaging boxes 4 are manually removed from the recycling station 50. Of course, the recycling station can be set up as another conveyor belt, which transports the unqualified packaging boxes 4 to the recycling point.

[0042] The operation process of the box flipping device provided in this application is as follows:

[0043] When the packaging box 4 is conveyed on the first conveyor belt 1 and passes the photoelectric sensor 52, if the packaging box 4 is not in a horizontal position, i.e., the first position t1, it is pushed out of the first conveyor belt 1 by the push cylinder 51. If the packaging box 4 is in the first position t1, it continues to move to the output end 10 of the first conveyor belt 1, and moves to the second position t2 under the action of gravity during the process of falling to the second conveyor belt 2 and continues to fall. When the packaging box 4 falls onto the second conveyor belt 2, under the influence of gravity and inertia, the packaging box 4 will be in the third posture t3, that is, the first side 40 of the packaging box 4 falls down first and contacts the second conveyor belt 2. Since the second running speed M2 of the second conveyor belt 2 is lower than the first running speed M1 of the first conveyor belt 1, the packaging box 4 will continue to flip to the fourth posture t4 under the influence of inertia. At this time, the second side 43 of the packaging box 4 comes into contact with the blocking part 302, thereby hindering the trend of the packaging box 4 to continue to flip, and it falls back to the vertical state, that is, the fifth posture t5. It is conveyed on the second conveyor belt 2 while maintaining the fifth posture t5, thus completing the 90° flip of the packaging box 4.

[0044] The box flipping device provided by this utility model can flip the packaging box 4 90° without additional driving components by using the height and speed difference of the two conveyor belts. It has a simple and reliable structure, occupies a small area and has high efficiency.

[0045] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
