Description

Technical Field

[0001] This utility model relates to the field of production operation technology, and in particular to a flipping device. Background Technology

[0002] The mattress manufacturing process involves flipping the mattress 180°. Currently, this crucial flipping action is generally performed manually by workers. Multiple workers typically work together, relying on their physical strength to lift one end of the mattress and use inertia to flip it over. This traditional manual labor method has significant drawbacks:

[0003] First, the labor intensity is extremely high, which is a severe test of the workers' physical fitness and can easily lead to muscle strain.

[0004] Secondly, low production efficiency, with the turnover speed limited by worker fatigue, makes it difficult to match the pace of automated production lines, becoming a bottleneck to improving overall efficiency;

[0005] Furthermore, there is a high safety risk. Heavy mattresses may slip during the flipping process due to loss of balance, posing a threat to the personal safety of the operator and the mattress product itself.

[0006] With the continuous rise in labor costs and the deepening of intelligent manufacturing transformation, this work method that relies on pure human labor is no longer able to meet the needs of modern, large-scale production.

[0007] Therefore, developing a dedicated automatic mattress flipping mechanism that can replace manual labor, is safe and efficient, and is easy to integrate into automated production lines is of urgent practical significance for improving the overall technical level and economic benefits of the mattress manufacturing industry.

[0008] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0059] See Figure 1 and Figure 2 The flipping device provided in this embodiment includes:

[0060] Fixed bracket 1;

[0061] Rotating platform 2, which is rotatably mounted on the fixed bracket 1 around a horizontal rotating shaft 2011, is used to place materials to be turned over;

[0062] Rotary drive unit 3, the drive end of the rotary drive unit 3 is connected to the horizontal rotating shaft 2011 for driving the rotating platform 2 to rotate relative to the fixed support 1;

[0063] The side clamping unit 4 includes two lateral clamping plates 401 arranged opposite each other along the horizontal rotating shaft 2011, and a slant direct drive assembly 402 that drives the two lateral clamping plates 401 to move closer to each other or further away from each other.

[0064] The flipping device provided in this embodiment operates as follows:

[0065] S10: Place the material to be flipped: First, place the material to be flipped (such as a mattress) stably on the rotating platform 2.

[0066] S20: Side clamping unit 4 clamps the material: The side clamping unit 4 is activated, and the two side clamping plates 401 are driven to move closer to each other through the inclined groove direct drive assembly 402, clamping the material to be flipped from both sides, ensuring that the material remains stable during the flipping process and preventing it from slipping.

[0067] S30: Rotary drive unit 3 drives the flipping: The rotary drive unit 3 is started. The drive end of the rotary drive unit 3 is connected to the horizontal rotating shaft 2011, driving the rotating platform 2 to rotate around the horizontal rotating shaft 2011 relative to the fixed support 1, thereby realizing the 180° up and down flipping of the material to be flipped.

[0068] S40: Side clamping unit 4 releases material: After the flipping is completed, the inclined chute direct drive assembly 402 is activated again, driving the two side clamping plates 401 to move away from each other, thereby releasing the material to be flipped. The material to be flipped falls naturally under the action of gravity onto the conveyor belt or transport vehicle that has been placed below the rotating platform 2, thus completing the mechanized up-and-down flipping operation of the material to be flipped.

[0069] Therefore, the flipping device provided by this utility model can perform mechanized up-and-down flipping operations on mattresses and other materials waiting to be flipped, thereby reducing labor costs and improving production efficiency.

[0070] See Figure 3 In this embodiment, the rotating platform 2 includes:

[0071] Platform base box 201, the platform base box 201 surrounds and forms an open accommodating cavity, and the horizontal rotating shaft 2011 is fixed to the outside of the platform base box 201;

[0072] A floating support plate 202 is located at the opening of the accommodating cavity and is slidably disposed relative to the platform base box 201;

[0073] A plurality of compression springs 203 are located between the platform base box 201 and the floating support plate 202, for driving the bottom surface of the floating support plate 202 away from the bottom of the accommodating cavity.

[0074] When the material to be flipped (such as a mattress) is placed smoothly on the floating support plate 202 of the rotating platform 2, the weight of the material compresses the compression spring 203 below, causing part of the floating support plate 202 to sink into the receiving cavity of the platform base box 201. This cushioning design can accommodate materials of different weights and provide stable support. At the same time, the compression spring 203 can provide cushioning support when placing materials, avoiding surface damage caused by rigid contact.

[0075] In this embodiment, the floating support plate 202 is provided with an axial guide groove 2021 parallel to the horizontal rotating shaft 2011; the lateral clamping plate 401 includes, in sequence, a clamping part 4011 exposed on the floating support plate 202, a limiting part 4012 located in the axial guide groove 2021, and a guide part 4013 connected to the inclined slot direct drive assembly 402.

[0076] Further, see Figure 2 and Figure 3 The inclined slot direct drive assembly 402 includes:

[0077] A sloping groove drive plate 4021 is located between the platform base box 201 and the floating support plate 202. The sloping groove drive plate 4021 is provided with an inclined guide groove 4021a that is inclined relative to the horizontal rotating shaft 2011 for each of the lateral clamping plates 401. The guide part 4013 is inserted into the corresponding inclined guide groove 4021a and is movably disposed relative to the sloping groove drive plate 4021 along the inclined guide groove 4021a.

[0078] The drive plate direct drive mechanism 4022 is connected to the inclined slot drive plate 4021 at its drive end, and is used to drive the inclined slot drive plate 4021 to reciprocate perpendicularly to the horizontal rotating shaft 2011.

[0079] Optionally, the distance between the two inclined guide grooves 4021a gradually decreases toward the drive plate direct drive mechanism 4022.

[0080] The detailed work process in step S20 above is as follows:

[0081] S201: The direct drive mechanism 4022 of the drive plate (such as a cylinder or electric push rod) is activated, pushing the inclined slot drive plate 4021 to move along the direction of the horizontal rotating shaft 2011.

[0082] S202: Since the inclined guide groove 4021a on the inclined groove drive plate 4021 is inclined, when the inclined groove drive plate 4021 is pushed, the groove wall of the inclined guide groove 4021a will squeeze the guide part 4013 inserted therein.

[0083] S203: The guide portion 4013 of each lateral clamp 401 is subjected to this tilting force. Since the guide portion 4013 is restricted in the axial guide groove 2021 of the floating support plate 202 by the limiting portion 4012 (the axial guide groove 2021 is parallel to the horizontal rotating shaft 2011), the lateral clamp 401 cannot follow the inclined drive plate 4021 to make axial movement, and the tilting force is decomposed into a component force that causes the lateral clamp 401 to move perpendicular to the horizontal rotating shaft 2011 (i.e., laterally).

[0084] S204: The continuous axial movement of the inclined groove drive plate 4021 forces the guide portions 4013 of the two side clamps 401 to slide along their respective inclined guide grooves 4021a, thereby converting the axial linear movement of the inclined groove drive plate 4021 into the lateral opposing linear movement of the two side clamps 401.

[0085] During the process described above, the two lateral clamping plates 401 drive their corresponding clamping parts 4011 to move closer together, clamping the material from both sides. Because the transmission mechanism is symmetrical and driven by the same inclined groove drive plate 4021, the synchronicity and alignment of the clamping actions are ensured.

[0086] In some embodiments, the clamping part 4011 is an inverted "L"-shaped clamp, which can not only clamp the material to be flipped laterally, but also limit its vertical movement. By adopting the inverted "L"-shaped clamp structure, the material to be flipped can be prevented from accidentally falling during the 180° vertical flipping process. After the flipping is completed, the inclined chute direct drive assembly 402 drives the two lateral clamps 401 away from each other, thereby releasing the material to be flipped without affecting the unloading of the material.

[0087] In this embodiment, the end face of the inclined groove drive plate 4021 and the side wall of the accommodating cavity are slidably connected by the guide rail slider assembly 5, thereby ensuring the smoothness and accuracy of the inclined groove drive plate 4021 moving along the horizontal rotating shaft 2011, reducing jamming and wear, and extending service life.

[0088] In this embodiment, the cross-sections of the axial guide groove 2021 and the limiting part 4012 are trapezoidal structures that gradually narrow toward the clamping part 4011, and the size of the clamping part 4011 is larger than the groove size of the axial guide groove 2021, so as to restrict the clamping part 4011 from passing through the axial guide groove 2021.

[0089] The cross-sections of the axial guide groove 2021 and the limiting part 4012 are both trapezoidal structures that gradually narrow towards the clamping part 4011, and the size of the clamping part 4011 is larger than the opening of the axial guide groove 2021, forming a reliable mechanical limit. The floating support plate 202 and the side clamping plate 401 can only slide relative to each other along the axial guide groove 2021 and cannot move up and down relative to each other, ensuring that the clamping action is always performed within the predetermined plane.

[0090] Furthermore, the depth to which the guide portion 4013 is inserted into the inclined guide groove 4021a is greater than the maximum sliding stroke of the floating support plate 202 relative to the lateral clamping plate 401. The up-and-down movement of the floating support plate 202 causes the lateral clamping plate 401 to move up and down, thereby ensuring that the guide portion 4013 never disengages from the inclined guide groove 4021a. This ensures continuous and reliable power transmission between the inclined groove drive mechanism and the side clamping unit 4.

[0091] Optionally, a roller is sleeved on the outside of the guide portion 4013. This converts the sliding friction between the guide portion 4013 and the inclined guide groove 4021a into rolling friction, significantly reducing motion resistance and wear, resulting in smoother operation, lower energy consumption, and longer service life.

[0092] In this embodiment, the rotary drive unit 3 includes:

[0093] Gear 301, the gear 301 being fixed to the horizontal rotating shaft 2011;

[0094] Rack 302, which meshes with gear 301;

[0095] The platform direct drive mechanism 303 has its drive end connected to the rack 302, and is used to drive the rack 302 to reciprocate so as to drive the gear 301 to rotate.

[0096] The rotary drive unit 3 adopts a structure in which the gear 301 is fixed to the horizontal rotating shaft 2011 and meshes with the rack 302 driven by the platform direct drive mechanism 303. It can convert the linear reciprocating motion of the rack 302 into the precise rotational motion of the gear 301 and the rotating platform 2. The transmission ratio is constant, the flip angle is accurately controlled, and the power output is stable and reliable.

[0097] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
