Abstract
Description
Technical Field
[0001] The utility model relates to a reversing conveying device. Background Art
[0002] Disposable absorbent products, such as diapers, sanitary napkins, breast pads and other products are usually folded and installed in packaging bags or packaging boxes. These disposable absorbent products are formed into a folded body shape that is folded in half or three times. However, due to the characteristics of the product structure itself, the folded body formed after folding has a relatively thick end and a relatively thin end. In the prior art, these folded bodies are usually stacked in sequence to form a stacked body, and the thick end forms a first side portion on one side and the thin end forms a second side portion on one side, so that the first side portion is thicker and the second side portion is thinner, which makes it difficult to package on the one hand, and on the other hand, the appearance of the formed packaging body is poor.
[0003] In the prior art, there are also conveying devices that reverse the folded body to form a staggered stack of thick ends and thin ends. These conveying devices can vertically flip or horizontally rotate single sheets one by one, but the structures of these existing devices are very complex and difficult to adapt to the high-speed production needs of disposable absorbent product production systems.

DETAILED DESCRIPTION
[0023] The embodiment of the utility model provides a reversing conveying device, and the application will be further described below with reference to the accompanying drawings.
[0024] At the same time, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0025] Please refer to the attached Figure 2 The reversing conveying device is used to convey the product 40. The product 40 is usually a folding body. Specifically, the folding body is usually formed by folding the body of a disposable absorbent product. The disposable absorbent product can be a sanitary napkin, a diaper, a breast pad, a disposable mattress, etc. The folding body can be formed by folding the disposable absorbent product in half, three or four times. However, it can be understood that other suitable products 40 or folding bodies formed by folding methods are not limited in the present invention. In addition, the product 40 should be roughly sheet-shaped and preferably be bendable. The reversing conveying device includes a first conveying section 11, a second conveying section 12, a third conveying section 13 and a fourth conveying section 14.
[0026] The first conveying section 11 is located upstream of the reversing conveying device, and is used to receive the product 40 and convey the product 40 to the second conveying section 12 or the third conveying section 13. In this embodiment, the first conveying section 11 is arranged Figure 1 The first conveying section 11 includes a first front conveying section 111 and a first rear conveying section 112, and the first front conveying section 111 is connected to the upstream equipment.
[0027] The second conveying section 12 and the third conveying section 13 are both located in the downstream direction of the first conveying section 11, wherein the second conveying section 12 includes a second front conveying section 121 and a second rear conveying section 122, and the third conveying section 13 includes a third front conveying section 131 and a third rear conveying section 132, wherein the second front conveying section 121, the third front conveying section 131 are adjacent to the first rear conveying section 112, and a spacing space 33 is included between the second front conveying section 121, the third front conveying section 131 and the first rear conveying section 112, and the product 40 can be received by the second front conveying section 121 or the third front conveying section 131 after passing through the spacing space 33.
[0028] The fourth conveying section 14 is arranged downstream of the second conveying section 12 and the third conveying section 13, and includes a supporting surface 261. The supporting surface 261 is used to receive the product 40 conveyed by the second conveying section 12 and the third conveying section 13; a reversing device 30 is also arranged downstream of the first rear conveying section 112, and the reversing device 30 includes a reversing plate 31. The reversing plate 31 is configured to allow the product 40 to enter the second conveying section 12 through the reversing plate 31 and be conveyed by the second conveying section 12, or to flexibly bend a part of the product 40 to the third front conveying section 131 and then be conveyed by the third conveying section 13, and the conveying directions of the second conveying section 12 and the third conveying section 13 are different.
[0029] Please refer to Figure 5 The reversing device 30 includes a reversing plate 31 and a driving device 32 for driving the reversing plate 31 to rotate. The reversing plate 31 is in a rotating state and is configured to allow the product 40 to enter the second conveying section 12 through the reversing plate 31 and be conveyed by the second conveying section 12 or to bend a part of the product 40 to the third front conveying section 131 and then be conveyed by the third conveying section 13. Specifically, when the reversing plate 31 enters the spacing space 33 and contacts the product 40 and applies an extrusion force to the product 40, a part of the product 40 is bent toward the direction of the third conveying section 13, and then the product 40 is clamped and conveyed by the third conveying section 13, thereby changing the movement direction of the product 40. When the reversing plate 31 is in the process of separating from the product 40 and applying an extrusion force to the product 40 again, the product 40 will smoothly pass through the spacing space 33 and be conveyed by the second conveying section 12.
[0030] Furthermore, the first rear conveying section 112 and the second front conveying section 121 have the same direction and corresponding positions, and the corresponding positions mean that the height of the second front conveying section 121 is basically the same as the height of the first rear conveying section 112, and the front end of the second front conveying section 121 is aligned with the rear end of the first rear conveying section 112, so that the product 40 can be directly taken over by the second front conveying section 121 for rear conveyance after passing through the spacing space 33.
[0031] Furthermore, the reversing plate 31 includes a resistance surface toward the first conveying section 11, and the resistance surface is basically perpendicular to the first rear conveying section 112. It can be understood that the third front conveying section 131 is parallel to the resistance surface and perpendicular to the first rear conveying section 112. With this arrangement, on the one hand, the driving device 32 can be installed horizontally and located in the space enclosed by the third conveyor belt 23, thereby saving overall space. On the other hand, the angle at which the product 40 is squeezed and bent is not too large, so that the product 40 can easily enter the third conveying section 13 and the product 40 can remain flat and reduce wrinkles.
[0032] Furthermore, the angle between the second front conveying section and the second rear conveying section is greater than or equal to 110°, and the angle between the third front conveying section and the third rear conveying section is greater than or equal to 110°, so that the product has smaller bending deformation when being conveyed in the second conveying section and the third conveying section.
[0033] It can be understood that in other embodiments, the diverter plate 31 can also be in the form of a push plate, which reciprocates in a direction parallel to the third front conveying section 131. In this embodiment, the push plate can reciprocate up and down. When the diverter plate 31 moves from top to bottom and contacts the product 40, a part of the product 40 is bent in the direction of the third conveying section 13. When the diverter plate 31 is located above the spacing space 33, the product 40 can pass through the spacing space 33 smoothly and be conveyed by the second conveying section 12.
[0034] Please refer to Figure 1 , Figure 3 , Figure 4 In this embodiment, the product 40 is in a clamped state when being conveyed in the first conveying section 11, the second conveying section 12 and the third conveying section 13, so that the product 40 is conveyed stably.
[0035] Specifically, the reversing conveying device includes a first conveyor belt 21, a second conveyor belt 22, a third conveyor belt 23, a fourth conveyor belt 24, a fifth conveyor belt 25 and a sixth conveyor belt 26, wherein the first conveyor belt 21 and the second conveyor belt 22 form a first conveying section 11, the third conveyor belt 23 and the fifth conveyor belt 25 form a second conveying section 12, and the fourth conveyor belt 24 and the first conveyor belt 21 form a third conveying section 13. At the same time, each conveyor belt is wound around a corresponding number of rollers and driving rollers, and the corresponding conveyor belt is driven by the driving roller to move.
[0036] It can be understood that the movement speed of each conveyor belt is the same.
[0037] It can be understood that when the product 40 is conveyed from the second conveying section 12 to the supporting surface 261, the direction is opposite to that when it is conveyed from the third conveying section 13 to the supporting surface 261. In the present embodiment, the second rear conveying section 122 and the third rear conveying section 132 are in opposite directions. Specifically, the second rear conveying section 122 conveys from the upper right to the lower left, and the third rear conveying section 132 conveys from the upper left to the lower right, so that the products 40 conveyed by the second conveying section 12 and the third conveying section 13 are in opposite directions after entering the supporting surface 261.
[0038] At the same time, in order to allow the product 40 to undergo smaller bending deformation during the conveying process, the first conveyor belt 21 includes a first front supporting section 211 and a first rear supporting section 212, and the second conveyor belt 22 includes a second front holding section 221 and a second rear holding section 222. The first front supporting section 211 and the second front holding section 221 form a first front conveying section 111, and the first front supporting section 211 and the second front holding section 221 are correspondingly arranged to form a clamping area to clamp the product 40 for conveying. Similarly, the first rear supporting section 212 and the second rear holding section 222 are correspondingly arranged to form a first rear conveying section 112.
[0039] At the same time, the third conveyor belt 23 includes a third front holding section 231 and a third rear holding section 232, and the fifth conveyor belt 25 includes a fifth front supporting section 251 and a fifth rear supporting section 252. The third front holding section 231 and the fifth front supporting section 251 form the second front conveying section 121, and the third rear holding section 232 and the fifth rear supporting section 252 form the second rear conveying section 122.
[0040] At the same time, the fourth conveyor belt 24 is arranged between the fifth conveyor belt 25 and the first conveyor belt 21, and the fourth conveyor belt 24 includes a fourth upper left clamping section 241 and a fourth lower left clamping section 242. The first conveyor belt 21 also includes a first upper right clamping section 213 and a first lower right clamping section 214. The fourth upper left clamping section 241 and the first upper right clamping section 213 are correspondingly arranged to form a third front conveying section 131, and the fourth lower left clamping section 242 and the first lower right clamping section 214 are correspondingly arranged to form a third rear conveying section 132.
[0041] Furthermore, if the angle between the second rear conveying section 122 and the supporting surface 261 is α, and the angle between the third rear conveying section 132 and the supporting surface 261 is β, then α is equivalent to β, and more preferably, α=β, so that the impact received by the product 40 when it falls from the second rear conveying section 122 to the supporting surface 261 is basically equivalent to the impact received when it falls from the third rear conveying section 132 to the supporting surface 261.
[0042] Furthermore, α=10~30°.
[0043] Furthermore, the sixth conveyor belt 26 forms the fourth conveying section 14, and the supporting surface 261 is the upward surface of the sixth conveyor belt 26, which is used to support the product 40 conveyed from the second conveying section 12 and the third conveying section 13. The downstream of the sixth conveyor belt 26 also includes a seventh conveyor belt 27, an eighth conveyor belt 28 and a ninth conveyor belt 29, wherein the eighth conveyor belt 28 is arranged downstream of the sixth conveyor belt 26 to receive the product 40 conveyed by the sixth conveyor belt 26, and the ninth conveyor belt 29 is arranged downstream of the eighth conveyor belt 28, and the eighth conveyor belt 28 and the ninth conveyor belt 29 are separately arranged. At the same time, the seventh conveyor belt 27 includes a seventh front holding section 271 and a seventh rear holding section 272, and the seventh front holding section 271 and the eighth conveyor belt 28 are correspondingly arranged to form a clamping area, and the seventh rear holding section 272 and the ninth conveyor belt 29 are correspondingly arranged to form another holding area, so that the product 40 is always in a clamping and conveying state.
