DETAILED DESCRIPTION

[0025] Preferred embodiments of the present application will be described in more detail with reference to the drawings. Although the preferred embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application is more thorough and complete, and the scope of the present application can be accurately conveyed to those skilled in the art.

[0026] Example 1

[0027] As shown in Figures 1-4 The present embodiment provides an automatic turnover mechanism for a box, which comprises a first belt line 1 and a second belt line 2, the first belt line 1 is located above the second belt line 2; the side surfaces of the first belt line 1 and the second belt line 2 are connected to a turnover frame 3, and the turnover frame 3 is connected to a turnover motor 4; the turnover motor 4 is used to drive the turnover frame 3 and the box 5 to turn a first angle when the box 5 reaches a turnover station 6 on the second belt line 2.

[0028] The first belt line 1 and the second belt line 2 are sequentially arranged from top to bottom in the height direction, and the two sides of the first belt line 1 are connected to the turnover frame 3, and the two sides of the second belt line 2 are connected to the turnover frame 3.

[0029] The turnover frame 3 is a rectangle with a hollow part, and the first belt line 1 and the second belt line 2 both extend from the hollow part of the turnover frame 3. The first belt line 1 and the second belt line 2 are parallel to each other. In this embodiment, the box 5 is taken as an example of a packaging box of an air conditioner indoor unit, and the height difference between the first belt line 1 and the second belt line 2 can be fixed or adjustable. If the positions of the first belt line 1 and the second belt line 2 are fixed, the height difference between the first belt line 1 and the second belt line 2 is equal to the height of the box 5. If the positions of the first belt line 1 and the second belt line 2 are adjustable, and the height difference between the first belt line 1 and the second belt line 2 is greater than the height of the box 5, the height of the first belt line 1 is adjusted downward by using a height adjusting mechanism, that is, the first belt line 1 moves toward the second belt line 2. If the positions of the first belt line 1 and the second belt line 2 are adjustable, and the height difference between the first belt line 1 and the second belt line 2 is less than the height of the box 5, the height of the first belt line 1 is adjusted upward by using a height adjusting mechanism, that is, the first belt line 1 moves away from the second belt line 2. The height adjusting mechanism can be a telescopic lifting rod or a lifting platform, and the first belt line 1 is detachably connected with the lifting rod or the lifting platform.

[0030] The first side of the second belt line 2 is provided with a feeding drum line 8. The box 5 moves toward the second belt line 2 along the feeding drum line 8, and then moves from the feeding drum line 8 to the second belt line 2. The second belt line 2 drives the feeding drum line 8 to continue to move forward until the box 5 moves to the turnover station 6, and then the second belt line 2 stops moving so as to fix the box 5 at the turnover station 6. The first belt line 1 abuts against the box 5, the first belt line 1 presses the box 5 downward, and the second belt line 2 drags the box 5 upward. Under the joint action of the first belt line 1 and the second belt line 2, the box 5 is clamped to prevent displacement.

[0031] The output shaft of the turnover motor 4 is connected with the turnover frame 3. After the box 5 moves to the turnover station 6, the output shaft of the turnover motor 4 drives the turnover frame 3 to turn clockwise or counterclockwise by a first angle. In this embodiment, the first angle is taken as an example of 180 degrees, so that the first belt line 1 is turned to the original position of the second belt line 2, and the second belt line 2 is turned to the original position of the first belt line 1, thereby driving the box 5 clamped between the first belt line 1 and the second belt line 2 to turn 180 degrees.

[0032] Since the unpacking and boxing processes of the split air conditioner indoor unit have been completed before the turnover, the box 5 automatic turnover mechanism of the utility model only performs the turnover operation on the box 5, and does not need to open both sides of the box 5. Therefore, the box 5 automatic turnover mechanism of the utility model can improve the product yield and production efficiency and reduce the labor cost without damaging the foam in the box 5.

[0033] This embodiment provides an automatic tilting mechanism for a box 5, including a first conveyor belt 1 and a second conveyor belt 2, with the first conveyor belt 1 located above the second conveyor belt 2. Both the sides of the first conveyor belt 1 and the second conveyor belt 2 are connected to a tilting frame 3, which is connected to a tilting motor 4. The tilting motor 4 drives the tilting frame 3 and the box 5 to tilt by a first angle when the box 5 reaches the tilting station 6 on the second conveyor belt 2. When the box 5 is transported onto the second conveyor belt 2, the second conveyor belt 2 continues to move forward until the box 5 reaches the tilting station 6, at which point the second conveyor belt 2 stops moving forward. The first conveyor belt 1 moves downward, clamping the box 5 under the combined action of the first conveyor belt 1 and the second conveyor belt 2. Then, the tilting motor 4 drives the tilting frame 3 to tilt by the first angle. The tilting frame 3 can tilt clockwise or counterclockwise. After the tilting frame 3 tilts by the first angle, the first conveyor belt 1 is located below the second conveyor belt 2, and the position of the first conveyor belt 1 is the same as the original position of the second conveyor belt 2, and the position of the second conveyor belt 2 is the same as the original position of the first conveyor belt 1. After the flipping is complete, the first conveyor belt 1 drives the box 5 forward, transporting it to the discharge structure, such as the discharge roller conveyor 10. The automatic flipping mechanism for the box 5 of this invention uses the first conveyor belt 1 and the second conveyor belt 2 to simultaneously clamp the box 5, thereby avoiding damage to the foam inside the box 5 and improving the product yield. The automatic flipping mechanism for the box 5 can automate the flipping of the box 5, thereby improving production efficiency and reducing labor costs.

[0034] Example 2

[0035] like Figures 1-6 As shown, this embodiment provides an automatic box flipping mechanism, including a first belt 1 and a second belt 2, with the first belt 1 located above the second belt 2; the sides of both the first belt 1 and the second belt 2 are connected to a flipping frame 3, and the flipping frame 3 is connected to a flipping motor 4; the flipping motor 4 is used to drive the flipping frame 3 and the box 5 to flip by a first angle when the box 5 reaches the flipping station 6 on the second belt 2.

[0036] A clamping mechanism is provided on the side of the first belt 1 away from the second belt 2, and the clamping mechanism is positioned towards the second belt 2.

[0037] The clamping mechanism includes a clamping cylinder 7, which is used to drive the first belt 1 to clamp the box 5 after the box 5 moves to the flipping station 6.

[0038] Several clamping cylinders 7 are arranged above the first belt conveyor 1. In this embodiment, two clamping cylinders 7 are used as an example. When the box body 5 moves to the flipping station 6, the push rods of the two clamping cylinders 7 extend, and the push rods drive the first belt conveyor 1 to press the box body 5 downward.

[0039] The first belt line 1 exerts a downward force on the box 5, and the second belt line 2 supports the box 5 upward, so that the second belt line 2 exerts an upward force on the box 5. Under the joint action of the first belt line 1 and the second belt line 2, the box 5 is in a force balance state, thereby fixing the box 5.

[0040] The overturning motor 4 drives the overturning frame 3 to overturn 180 degrees counterclockwise, so that the first belt line 1 overturns to the position originally occupied by the second belt line 2, and the second belt line 2 overturns to the position originally occupied by the first belt line 1. At this time, the second belt line 2 is located above the first belt line 1. The push rod of the two clamping cylinders 7 drives the first belt line 1 to retract, and then the first belt line 1 is started to move. The first belt line 1 starts to move and transports the box 5 on the first belt line 1 to the discharge roller line 10. The overturning motor 4 drives the overturning frame 3 to overturn 180 degrees clockwise, so that the first belt line 1 and the second belt line 2 return to the original position, that is, the first belt line 1 and the second belt line 2 both return to the original position, and the first belt line 1 is located above the second belt line 2.

[0041] The above operation process is the process of overturning one box 5. The box 5 of the embodiment is a packaging box of an air conditioner indoor unit. After completing the overturning process of one box 5, the above process is repeated to overturn the next box 5.

[0042] The first belt line 1 of the embodiment is provided with a clamping mechanism on the side away from the second belt line 2, and the clamping mechanism is arranged towards the second belt line 2. The clamping mechanism includes a clamping cylinder 7, which is used to drive the first belt line 1 to clamp the box 5 after the box 5 moves to the overturning station 6. Two clamping cylinders are arranged above the first belt line 1. When the box 5 moves to the overturning station 6, the push rod of the two clamping cylinders 7 extends, and the push rod drives the first belt line 1 to press the box 5 downward. The first belt line 1 exerts a downward force on the box 5, and the second belt line 2 supports the box 5 upward, so that the second belt line 2 exerts an upward force on the box 5. Under the joint action of the first belt line 1 and the second belt line 2, the box 5 is in a force balance state, thereby fixing the box 5.

[0043] Embodiment 3

[0044] As shown in Figures 1-6 The embodiment provides an automatic box overturning mechanism, which comprises a first belt line 1 and a second belt line 2, the first belt line 1 is located above the second belt line 2; the side surfaces of the first belt line 1 and the second belt line 2 are connected with an overturning frame 3, and the overturning frame 3 is connected with an overturning motor 4; the overturning motor 4 is used to drive the overturning frame 3 and the box 5 to overturn by a first angle when the box 5 reaches an overturning station 6 on the second belt line 2.

[0045] The first side of the second belt line 2 is provided with an infeed cylinder line 8, which is provided with a guide structure 9 and is used to transport the box 5 onto the second belt line 2.

[0046] The second side of the second belt line 2 is provided with an outfeed cylinder line 10, which is used to transport the overturned box 5.

[0047] The infeed cylinder line 8 and the outfeed cylinder line 10 are respectively arranged on the two sides of the second belt line 2 before overturning, and the guide structure 9 is arranged on the side of the infeed cylinder line 8 away from the second belt line 2. The guide structure 9 includes two oppositely arranged guide plates, which extend along the length direction of the infeed cylinder line 8. The guide plates are divided into two parts, one part is a horizontal section, and the other part is a gradual change section. The horizontal section is arranged close to the second belt line 2, and the gradual change section is arranged away from the second belt line 2. The horizontal section is connected or integrally formed with the gradual change section.

[0048] The gradual change section of the guide plate gradually extends outward from the side close to the second belt line 2 to the side away from the second belt line 2, that is, the gradual change sections of the two guide plates are oppositely arranged, and the distance between the two gradual change sections becomes smaller as they are closer to the second belt line 2. The box 5 enters a larger opening formed between the two gradual change sections, and then the opening gradually narrows. The two guide plates play a guiding role on the box 5 on the infeed cylinder line 8, and further limit the box 5.

[0049] After the box 5 is guided by the gradual change sections of the two guide plates, it enters the area between the horizontal sections of the two guide plates and continues to move towards the second belt line 2 until the infeed cylinder line 8 transports the box 5 onto the second belt line 2. After the box 5 reaches the second belt line 2, the second belt line 2 drives the box 5 to continue to move forward until the box 5 reaches the overturning station 6, and the second belt line 2 stops moving.

[0050] The first belt line 1 moves downward, and the box 5 is clamped under the joint action of the first belt line 1 and the second belt line 2. The overturning motor 4 drives the overturning frame 3 to overturn 180 degrees counterclockwise, so that the first belt line 1 overturns to the original position of the second belt line 2, and the second belt line 2 overturns to the original position of the first belt line 1. At this time, the second belt line 2 is located above the first belt line 1.

[0051] After the flipping operation is completed, the flipped box 5 is located above the first conveyor belt 1. The first conveyor belt 1 starts and drives the flipped box 5 to continue moving forward, transporting the flipped box 5 from the first conveyor belt 1 to the discharge roller conveyor 10. The flipped box 5 continues to move forward with the discharge roller conveyor 10 until the flipped box 5 moves to the discharge position.

[0052] The feed roller conveyor 8 and the discharge roller conveyor 10 are independent of each other, and are controlled by two separate drive devices. The speeds of the feed roller conveyor 8 and the discharge roller conveyor 10 can be equal or unequal, which is not limited here.

[0053] In this embodiment, a feeding roller 8 is provided on the first side of the second conveyor belt 2, and a guide structure 9 is provided on the feeding roller 8. The feeding roller 8 is used to transport the box 5 onto the second conveyor belt 2.

The guide structure 9 includes two guide plates arranged opposite each other, and the guide plates extend along the length direction of the feeding roller 8. The guide plates are divided into two parts, one part being a horizontal section and the other part being a gradient section. The horizontal section is located close to the second conveyor belt 2, and the gradient section is located away from the second conveyor belt 2. The horizontal section and the gradient section are connected or integrally formed. The box 5 enters through a larger opening formed between two transition sections, and then the opening gradually narrows. The two guide plates guide the box 5 on the feed roller line 8 and further limit the position of the box 5.

[0054] Example 4

[0055] like Figures 1-6 As shown, this embodiment provides an automatic box flipping mechanism, including a first belt 1 and a second belt 2, with the first belt 1 located above the second belt 2; the sides of both the first belt 1 and the second belt 2 are connected to a flipping frame 3, and the flipping frame 3 is connected to a flipping motor 4; the flipping motor 4 is used to drive the flipping frame 3 and the box 5 to flip by a first angle when the box 5 reaches the flipping station 6 on the second belt 2.

[0056] The automatic tilting mechanism for the box also includes a first belt motor 11, the output shaft of which is connected to a first roller 12, and the outer side of the first roller 12 is connected to the first belt line 1.

[0057] The box automatic overturning mechanism further comprises a second belt motor 13, an output shaft of the second belt motor 13 is connected with a second roller 14, and the outer side of the second roller 14 is connected with the second belt line 2.

[0058] The output shaft of the first belt motor 11 is inserted into the mounting hole of the first roller 12, and when the first belt motor 11 works, the output shaft of the first belt motor 11 rotates to drive the first roller 12 to rotate. The first belt line 1 is wrapped on the outer side of the first roller 12, and the first roller 12 rotates to drive the first belt line 1 to rotate.

[0059] The output shaft of the second belt motor 13 is inserted into the mounting hole of the second roller 14, and when the second belt motor 13 works, the output shaft of the second belt motor 13 rotates to drive the second roller 14 to rotate. The second belt line 2 is wrapped on the outer side of the second roller 14, and the second roller 14 rotates to drive the second belt line 2 to rotate.

[0060] The first belt motor 11 and the second belt motor 13 are independently controlled. When the box 5 moves from the feeding roller line 8 to the second belt line 2, the second belt motor 13 is started, the second belt motor 13 drives the second belt line 2 to move forward, and the box 5 moves forward together with the second belt line 2 until the box 5 moves to the overturning station 6. The overturning motor 4 drives the overturning frame 3 to overturn 180 degrees counterclockwise, so that the first belt line 1 is located at the original position of the second belt line 2, and the second belt line 2 is located at the original position of the first belt line 1. At this time, the box 5 completes the overturning operation. The overturned box 5 is located on the first belt line 1, the first belt motor 11 is started, the first belt motor 11 drives the first belt line 1 to move forward, and the overturned box 5 moves forward together with the first belt line 1. The first belt line 1 transports the overturned box 5 to the discharging roller line 10.

[0061] The second belt line 2 is provided with a blocking mechanism 17 on the side close to the discharging roller line 10, the blocking mechanism 17 is located between the first belt line 1 and the second belt line 2, and the blocking mechanism 17 is used for blocking the box 5 from entering the discharging roller line 10 before overturning the box 5 and for allowing the box 5 to enter the discharging roller line 10 after overturning the box 5.

[0062] The blocking mechanism 17 is a frame with a baffle, and the height of the blocking mechanism 17 is less than the height of the box 5. When the box 5 is transported from the feeding roller line 8 to the second belt line 2, the second belt line 2 drives the box 5 to continue to move forward until the box 5 moves to the overturning station 6. The blocking mechanism 17 is arranged. If the second belt line 2 does not stop running in time, the box 5 continues to move forward beyond the overturning station 6, the baffle abuts against the box 5 to limit the box 5, and the box 5 is prevented from moving from the second belt line 2 to the discharging roller line 10 before the overturning operation.

[0063] After the flipping operation of the box 5 is completed, the second conveyor belt 2 is located at the original position of the first conveyor belt 1. The blocking mechanism 17 flips to above the flipped box 5, and the blocking mechanism 17 no longer blocks the flipped box 5. The flipped box 5 can move forward with the first conveyor belt 1, and the first conveyor belt 1 transports the flipped box 5 to the discharge roller conveyor 10.

[0064] The automatic tilting mechanism for the box 5 in this embodiment also includes a first belt motor 11, the output shaft of which is connected to a first roller 12, and the outer side of the first roller 12 is connected to the first conveyor belt 1. The automatic tilting mechanism for the box 5 also includes a second belt motor 13, the output shaft of which is connected to a second roller 14, and the outer side of the second roller 14 is connected to the second conveyor belt 2. The first belt motor 11 and the second belt motor 13 are controlled independently. When the box 5 moves from the feeding roller conveyor 8 to the second conveyor belt 2, the second belt motor 13 is activated, driving the second conveyor belt 2 forward. The box 5 moves forward along with the second conveyor belt 2 until it reaches the tilting station 6. After tilting, the box 5 is located on the first conveyor belt 1. The first belt motor 11 is then activated, driving the first conveyor belt 1 forward. The tilted box 5 moves forward along with the first conveyor belt 1, which transports the tilted box 5 to the discharge roller conveyor 10.

In this embodiment, two clamping cylinders 7 are taken as an example, the clamping cylinder 7 is towards the driving plate 16, the two push rods of the clamping cylinder 7 are extended, and the two push rods are in abutment with the driving plate 16. The two push rods exert a downward force on the driving plate 16, and since the fixed plate 15 connects the driving plate 16 and the first belt line 1, the first belt line 1 exerts a downward force on the box 5 between the first belt line 1 and the second belt line 2.

[0071] The driving plate 16 is arranged between the first belt line 1 and the clamping cylinder 7, and the fixed plate 15 is used to connect the driving plate 16 and the first belt line 1, which can avoid the direct contact between the clamping cylinder 7 and the first belt line 1, thereby preventing the clamping cylinder 7 from damaging the first belt line 1. The driving plate 16 and the fixed plate 15 jointly transmit the force provided by the clamping cylinder 7 to the first belt line 1. Before the turning operation, the driving plate 16 and the fixed plate 15 jointly transmit the force for pressing the box 5 downward to the first belt line 1. After the turning operation, the driving plate 16 and the fixed plate 15 jointly transmit the downward force provided by the clamping cylinder 7 to the first belt line 1, drive the first belt line 1 to retract, and the first belt line 1 drives the turned box 5 to move to the discharge roller line 10.

In this embodiment, the driving plate 16 is arranged between the first belt line 1 and the clamping cylinder 7, and the fixed plate 15 is used to connect the driving plate 16 and the first belt line 1, which can avoid the direct contact between the clamping cylinder 7 and the first belt line 1, thereby preventing the clamping cylinder 7 from damaging the first belt line 1. The driving plate 16 and the fixed plate 15 jointly transmit the force provided by the clamping cylinder 7 to the first belt line 1.

[0073] The foregoing is considered as illustrative only of the principles of the application. Other variations and modifications can be made to the above-described embodiments consistent with the principles of the present application. Accordingly, the scope of protection is not limited to that of the described embodiments but is only limited by the claims that follow, that scope including all equivalents of the subject matter of the claims. Number of embodiments have been described in detail herein. However, specific structures and characteristics described herein are merely examples and do not limit the scope of the application. It is clear that many modifications and variations of the described embodiments are possible and are thus intended to be covered by the application. For example, the above-described embodiments can be implemented in either hardware or software. The scope of the application is defined by the appended claims and their equivalents.

[0074] It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if a device described herein is turned over in use or operation, a relative preposition such as "above", "below", "upper", "lower", and the like can be reversed. Accordingly, the exemplary term "above" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0075] In addition, it should be noted that the use of "first", "second", and the like does not necessarily indicate that two steps or items discussed in succession are one before the other in time. Rather, such nomenclature is generally used to distinguish two steps or items from one another, but does not necessarily indicate a specific order in time.

[0076] The preferred embodiments of the present application have been described above. It is understood, however, that the present application can be practiced with modifications and changes within the scope and spirit of the present application. Accordingly, the application is not limited to that of the described embodiments but is only limited by the scope of the appended claims, and their equivalents.
