Abstract
Description
Technical Field
[0001] This invention relates to the field of palletizing technology, and more specifically, to a palletizing and conveying device for mattresses and a method for adjusting the conveying position of mattresses. Background Technology
[0002] Currently, mattresses tend to become misaligned during stacking and transport. One vertex of the mattress initially contacts the baffle, and as transport continues, the mattress rotates to bring the other vertex into contact with the baffle, thus correcting its position. However, when the mattress is misaligned at a large angle, the correction efficiency is low, impacting production efficiency. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mattress palletizing and conveying device and a mattress conveying position adjustment method to quickly adjust the mattress alignment and improve production efficiency.

[0005] The invention is further configured such that a baffle is installed on one side of the second moving plate, the baffle is located at the front end of the mattress conveying direction, the baffle is equipped with a cam, the cam can rotate along its own axis, and in the initial state the minor diameter of the cam is parallel to the mattress conveying direction, the mattress is conveyed to the minor diameter end of the cam and stops.
[0006] The invention is further configured such that the two second rotating drums rotate in the same or opposite directions.
[0007] The present invention is further configured such that the rotating shaft and the second rotating cylinder are connected by a bearing.
[0008] The invention is further configured to include a sleeve, which is fitted onto a rotating shaft. The rotation of the rotating shaft drives the sleeve to rotate synchronously. An extension cylinder is fixedly installed on a second rotating cylinder. The extension cylinder is located on the side of the second rotating cylinder away from the first rotating cylinder. The sleeve is inserted into the extension cylinder and can move radially. A fixing ring is installed on the sleeve. The outer wall of the fixing ring has a protrusion, and the inner wall of the extension cylinder has a groove. The outer wall of the fixing ring abuts against the inner wall of the extension cylinder so that the protrusion is inserted into the groove. The rotation of the sleeve drives the extension cylinder to rotate, thereby causing the second rotating cylinder to rotate synchronously with the first rotating cylinder.
[0009] The invention is further configured to include a plug rod, which is inserted into a rotating shaft and is movable along the axial direction of the rotating shaft. The plug rod is equipped with a rotating block, which has a conical portion. A sleeve is equipped with a second fixing plate, which abuts against the conical portion.
[0010] The invention is further configured such that a roller is mounted on the second fixing plate, the roller is rotatable along its own axis, the roller abuts against the cone, and the tangent between the roller and the cone is set along a generatrix of the cone, the generatrix passing through the point of tangency between the roller and the cone.
[0011] The invention is further configured such that the insertion rod and the rotating block are connected by a bearing.
[0012] The invention is further configured such that a first support cylinder and a second support cylinder are installed on both sides of the rotating shaft, and a limiting component is fixedly installed on the sleeve. The limiting component is inserted into the rotating shaft and passes through the first support cylinder, the rotating shaft, and the second support cylinder. The length direction of the limiting component is arranged along the radial direction of the rotating shaft. The limiting component is fitted with a spring, one end of the spring abuts against the second support cylinder and the other end abuts against the inner wall of the sleeve. The spring and the fixing ring are respectively located on both sides of the sleeve.
[0013] The present invention also adopts the following technical solution: a mattress conveying position adjustment method, using a mattress palletizing and conveying device, comprising the following steps:
[0014] ① The first rotating drum rotates to transport the mattress, and the second rotating drum rotates synchronously with the first rotating drum to transport the mattress;
[0015] ② Reverse one of the second rotating cylinders so that the two second rotating cylinders rotate in opposite directions to rotate the mattress and adjust its position.
[0016] In summary, the present invention has the following beneficial effects:
[0017] When the mattress is significantly tilted, the conveyor assembly cannot quickly adjust its position to straighten it. By using two second rotating drums that rotate in opposite directions, the mattress can be rotated to quickly adjust its position, thereby improving production efficiency. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] like Figure 2 As shown, this embodiment discloses a mattress palletizing and conveying device, including a palletizing bracket 1, a conveyor chain 11 mounted on the palletizing bracket 1, a first movable plate 12 fixedly mounted on the conveyor chain 11, and a conveyor roller 13 rotatably connected to the first movable plate 12. The first movable plate 12 is located at both ends of the axial direction of the conveyor roller 13, and the conveyor roller 13 is along the horizontal conveying direction (…). Figure 2 Multiple conveyor rollers 13 are arranged in the middle (from right to left). The conveyor rollers 13 are driven by a motor and chain drive to rotate along their own axis for conveying mattresses 3.
[0028] like Figure 2 As shown, the palletizing and conveying device also includes a first moving module 2, which is movably connected to a second moving module 21. The second moving module 21 can move left and right, and is movably connected to a second moving plate 22, which can move up and down.
[0029] The second movable plate 22 is equipped with a conveying assembly 5 for conveying the mattress 3. The second movable plate 22 is located at both ends of the axial direction of the conveying assembly 5. Multiple conveying assemblies 5 are provided. The conveying assembly 5 is connected to the conveying roller 13 so that the mattress 3 is conveyed from the conveying roller 13 to the conveying assembly 5.
[0030] like Figure 2 , Figure 3 As shown, a baffle 4 is installed on the side of the second moving plate 22 away from the conveying roller 13. The baffle 4 is located at the front end of the mattress 3 in the conveying direction. The baffle 4 includes side plates 41 on both sides, and a shaft 42 is installed between the two side plates 41. The shaft 42 is driven by a motor to rotate along its own axis. A cam 43 is installed on the shaft 42, and the shaft 42 passes through the cam 43. The rotation of the shaft 42 drives the cam 43 to rotate synchronously. In the initial state, the small diameter of the cam 43 is parallel to the conveying direction of the mattress 3. The mattress 3 is conveyed until it stops at the small diameter end of the cam 43. Because the position of the mattress 3 will be skewed during the conveying process, one vertex of the mattress 3 first abuts against the cam 43. Under the continuous conveying of the conveying assembly 5, the mattress 3 rotates so that the other vertex also abuts against the cam 43, thereby completing the position adjustment. That is, the mattress 3 is... Figure 3 The position shown is for easy gripping by the robotic arm.
[0031] like Figure 4 , Figure 5 As shown, the conveying assembly 5 includes a rotating shaft 51, which is rotatable along its own axis. Specifically, the two ends of the rotating shaft 51 are inserted into the second moving plates 22 on both sides. The rotating shaft 51 and the second moving plates 22 are connected by bearings. The rotating shaft 51 is equipped with a first sprocket 513, which rotates through chain drive to drive the rotating shaft 51 to rotate along its own axis.
[0032] like Figure 5 As shown, a first rotating cylinder 52 is mounted on a rotating shaft 51. The rotating shaft 51 is inserted into the first rotating cylinder 52, and the rotating shaft 51 and the first rotating cylinder 52 are connected by a key. Rotation of the rotating shaft 51 drives the first rotating cylinder 52 to rotate synchronously. A second rotating cylinder 53 is rotatably connected to the outer wall of the rotating shaft 51. The second rotating cylinder 53 is located at both axial ends of the first rotating cylinder 52. Specifically, the rotating shaft 51 passes through the second rotating cylinder 53, and the rotating shaft 51 and the second rotating cylinder 53 are connected by bearings. An extension cylinder 531 is fixedly mounted on the second rotating cylinder 53. The extension cylinder 531 is located on the side of the second rotating cylinder 53 away from the first rotating cylinder 52. A second sprocket 5311 is mounted on the extension cylinder 531. Figure 7 As shown, the second sprocket 5311 is connected to the third sprocket 5312 via chain drive. The third sprocket 5312 is connected to the motor and driven to rotate. The second sprocket 5311 rotates via chain drive to drive the extension cylinder 531 and the second rotating cylinder 53 to rotate synchronously.
[0033] The second rotating drum 53 and the first rotating drum 52 are driven independently to achieve a rotation direction that is the same as or opposite to that of the first rotating drum 52, and the rotation directions of the two second rotating drums 53 are the same or opposite. Specifically, when the rotation direction of the first rotating drum 52 is the same as that of the two second rotating drums 53, the mattress 3 can be transported more smoothly; when the rotation directions of the two second rotating drums 53 are opposite, the two second rotating drums 53 create a rotation effect on the mattress 3, which facilitates quick adjustment of the position of the mattress 3. That is... Figure 1 As shown, one vertex of the mattress 3 is pressed against the middle of the cam 43. At this time, the mattress 3 is significantly tilted, and the conveying assembly 5 cannot quickly adjust the position of the mattress 3 to straighten it. The two second rotating drums 53 rotate in opposite directions to create a rotational effect on the mattress 3, thereby quickly adjusting its position and improving production efficiency. The significant tilt of the mattress 3 is detected by sensors 221, which are located on both sides of the cam 43 along its axial direction. When both sensors 221 detect that the mattress 3 is far from its position, it is determined that one vertex of the mattress 3 is pressed against the middle of the cam 43, requiring rapid adjustment.
[0034] When the cam 43 rotates to push the mattress 3 to the right, it helps to adjust the position of the mattress 3 so that the first rotating drum 52 can rotate the mattress 3 to quickly adjust the position of the mattress 3. At the same time, while the cam 43 rotates to push the mattress 3 to the right, the first rotating drum 52 reverses the flow to quickly push the mattress 3 back.
[0035] like Figure 5 As shown, the sleeve 6 is fitted onto the rotating shaft 51. The rotation of the rotating shaft 51 drives the sleeve 6 to rotate synchronously. The sleeve 6 is inserted into the extension cylinder 531 and can move radially. Specifically, a first support cylinder 511 and a second support cylinder 512 are installed on both sides of the rotating shaft 51. A limiting component 62 is fixedly installed on the sleeve 6. The limiting component 62 is inserted into the rotating shaft 51 and passes through the first support cylinder 511, the rotating shaft 51, and the second support cylinder 512. The length direction of the limiting component 62 is arranged radially along the rotating shaft 51. A spring 63 is fitted onto the limiting component 62. One end of the spring 63 abuts against the second support cylinder 512, and the other end abuts against the inner wall of the sleeve 6. The spring 63 and the fixing ring 61 are located on both sides of the sleeve 6, respectively.
[0036] The sleeve 6 includes a rod 71 that is inserted into a rotating shaft 51. The rod 71 is connected to a drive component 7 to move axially along the shaft 51. A rotating block 72 is mounted on the rod 71, and the rod 71 and the rotating block 72 are connected by a bearing. The rotating block 72 can rotate along its own axis. The rotating block 72 has a tapered portion 721, the outer wall of which is tapered, and the small-diameter end of which is located away from the rod 71. A first fixing plate 64 is fixedly mounted on the inner wall of the sleeve 6, and a second fixing plate 65 is fixedly mounted on the first fixing plate 64. A roller 651 is mounted on the second fixing plate 65 and can rotate along its own axis. The roller 651 abuts against the tapered portion 721, and the tangent between the roller 651 and the tapered portion 721 is set along a generatrix of the tapered portion 721, which passes through the point of tangency between the roller 651 and the tapered portion 721.
[0037] like Figure 5 , Figure 6 As shown, the sleeve 6 is equipped with a retaining ring 61. The outer wall of the retaining ring 61 has protrusions that are evenly distributed along the circumference of the retaining ring 61. The inner wall of the extension cylinder 531 has a groove. When the cone 721 extends into the rotating shaft 51, the cone 721 pushes the sleeve 6 to move the sleeve 6 radially until the outer wall of the retaining ring 61 abuts against the inner wall of the extension cylinder 531, causing the protrusions to insert into the grooves. The sleeve 6 rotates, driving the extension cylinder 531 to rotate, thereby causing the second rotating cylinder 53 to rotate synchronously with the first rotating cylinder 52. When the second rotating cylinder 53 and the first rotating cylinder 52 rotate synchronously, the third sprocket 5312 is the driven wheel. By achieving synchronous rotation of the second rotating cylinder 53 and the first rotating cylinder 52, the mattress 3 can be transported more smoothly.
[0038] A method for adjusting the position of a mattress conveyor, using the aforementioned mattress palletizing and conveying device, specifically includes the following steps:
[0039] ① The first rotating drum 52 rotates to transport the mattress 3, and the second rotating drum 53 rotates synchronously with the first rotating drum 52 to transport the mattress 3.
[0040] ② One vertex of the mattress 3 abuts against the cam 43, and the first rotating drum 52 continues to rotate in the same direction to deliver the mattress 3 so that the other vertex of the mattress 3 also abuts against the cam 43, thereby straightening the mattress 3.
[0041] When one of the apexes of the mattress 3 abuts against the middle position of the cam 43, one of the second rotating cylinders 53 reverses, so that the two second rotating cylinders 53 rotate in opposite directions, thereby creating a rotation effect on the mattress 3 to quickly adjust the position of the mattress 3.
[0042] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
