Description

Technical Field

[0001] The present invention relates to the technical field of packaging and packing equipment, in particular to a corner protecting machine. Background Art

[0002] A mattress is an item that is placed between the human body and the bed to ensure that consumers get a healthy and comfortable sleep. Mattresses are made of a variety of materials, and mattresses made of different materials can bring different sleeping effects. With the continuous advancement of material civilization and technological processes, the types of mattresses used by modern people have gradually become diversified, mainly including: spring mattresses, palm mattresses, latex mattresses, water mattresses, inclined spine protection mattresses, air mattresses, magnetic mattresses, etc. Among these mattresses, spring mattresses account for a large proportion.

[0003] Currently, mattresses and other products usually need to be packaged with strapping tape before transportation. With the promotion of automatic packaging technology, packaging machines with automatic packaging functions have become widely used. Since the corners of mattresses are most vulnerable to damage during transportation, during the mattress packaging process, after wrapping the packaging material on the surface of the mattress, it is necessary to wrap corner guards at the four corners of the mattress as an additional layer of protection. Corner guards are usually made of materials such as pearl cotton or cardboard and need to be packaged manually. Therefore, how to design a corner protection machine that can automatically package is the technical problem to be solved by the present invention. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art and provide a corner protection machine.

[0005] A corner protection machine includes a conveying platform, a positioning device, a covering device, and a gluing device;

[0006] The positioning device is provided on the conveying platform and is used to locate the position of the mattress on the conveying platform;

[0007] The covering device includes a first pressing plate and a second pressing plate. The covering device drives the first pressing plate to press one end of the packaging material toward one side of the corner of the mattress, and the covering device drives the second pressing plate to press the other end of the packaging material toward the other side of the corner of the mattress.

[0008] The gluing device fixes the packaging material on the mattress.

[0009] The corner protection machine described in the present invention realizes automatic covering of the packaging material on the corners of the mattress by providing a covering device, and automatically fixes the packaging material on the mattress by a gluing device. The present invention has a compact structure and reduces the packaging cost.

[0010] Furthermore, it also includes a base, a movable frame and a movable drive mechanism; the movable frame is slidably arranged on the base along the width direction of the conveying platform; the coating device and the gluing device are arranged on the movable frame; the movable drive mechanism drives the movable frame to move on the base.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that the movable frames can be respectively set on both sides of the mattress, and the movable frames on both sides can be driven to approach or move away from the mattress at the same time by the mobile driving mechanism. At the same time, a covering device is provided on each movable frame, thereby achieving the covering of the corners on both sides of the mattress at the same time.

[0012] Furthermore, the covering device also includes a flipping drive mechanism and a pushing drive mechanism; the flipping drive mechanism is arranged on the movable frame, and the flipping drive mechanism drives the first pressure plate to press toward one side of the corner of the mattress; the pushing drive mechanism is arranged on the first pressure plate, and the pushing drive mechanism drives the second pressure plate to press toward the other side of the corner of the mattress.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that the first pressing plate can be first in a horizontal state, and then by placing the packaging material on the first pressing plate, one end of the packaging material is located on the first pressing plate, and the other end of the packaging material is located outside the first pressing plate; then the flip driving mechanism is used to drive the first pressing plate and one end of the packaging material to be pressed toward one side of the corner of the mattress, and then the second pressing plate is driven to move by the pushing driving mechanism, so that the other end of the packaging material is bent and covered on the other side of the corner of the mattress; since the corner of the mattress is generally 90 degrees, the movement direction of the second pressing plate is set perpendicular to the surface of the first pressing plate, so that when the pushing driving mechanism pushes the second pressing plate, the packaging material can be bent into 90 degrees.

[0014] Furthermore, the covering device also includes a fixing mechanism; the fixing mechanism includes a plurality of fixed driving sources and a plurality of steel needles; the fixed driving source is arranged at the bottom of the first pressure plate; the steel needles are arranged on the output end of the fixed driving source; and a through hole is provided on the surface of the first pressure plate for the steel needles to pass through.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that, by setting up a fixing mechanism, after placing the packaging material on the first pressure plate, the packaging material can be punctured by a steel needle and fixed on the first pressure plate, thereby preventing the packaging material from falling during the flipping of the first pressure plate; the fixing mechanism is preferably a V-shaped needle suction cup, that is, the fixed driving source and the arrangement of the steel needles are V-shaped, which can better puncture and fix the packaging material.

[0016] Furthermore, it also includes a feeding device arranged on the mobile frame; the feeding device includes a feeding roller, a first conveying roller group, a second conveying roller group and a cutting mechanism;

[0017] The feeding roller is rotatably arranged on the movable frame and is provided with packaging materials;

[0018] The first conveying roller group and the second conveying roller group are arranged adjacent to each other and convey in the same direction; the packaging material passes through the first conveying roller group and the second conveying roller group in sequence and is conveyed to the first pressing plate;

[0019] The cutter mechanism is disposed between the first conveying roller group and the second conveying roller group and is used for cutting the packaging material;

[0020] The turnover drive mechanism is slidably arranged on the movable frame and reciprocates between the loading device and the mattress.

[0021] The beneficial effect of adopting the above-mentioned further scheme is that by setting up a loading device, the rolled packaging material can be automatically transported to the first pressing plate, and then the packaging material is cut by the cutting mechanism to make the packaging material cut into a suitable length. Then, the flipping drive mechanism and the first pressing plate can wrap the cut packaging material on the corner of the mattress, realizing full automation of corner protection packaging.

[0022] Furthermore, the loading device also includes a guide plate; the guide plate is arranged at the output position of the second conveying roller group, and the first pressing plate can be moved to the bottom of the guide plate.

[0023] The beneficial effect of adopting the above further solution is that by setting the guide plate, the packaging material can be conveyed between the guide plate and the first pressing plate, so that the packaging material is better conveyed to the first pressing plate, and the fixing mechanism can better fix the packaging material on the first pressing plate.

[0024] Furthermore, the gluing device includes several sticker machines; the sticker machine includes a frame, a glue paper roller, a positioning wheel, a positioning plate, a cutting knife and a cutting drive source; the frame is movably arranged on the movable frame; the glue paper roller is rotatably arranged on the frame and is rolled with glue paper; the positioning wheel is rotatably arranged on the frame; the positioning plate is arranged on the frame and presses against the positioning wheel; the cutting knife and the cutting drive source are arranged on the frame and are located below the positioning wheel, and the output end of the cutting drive source is connected to the cutting knife; the glue paper is output from the glue paper roller and passes between the positioning wheel and the positioning plate.

[0025] The beneficial effect of adopting the above further solution is that after the packaging material is pressed toward the two sides of the corner of the mattress by the first pressing plate and the second pressing plate, a certain length of the packaging material is reserved outside the edge of the first pressing plate and the second pressing plate, and the packaging material is automatically affixed to the reserved length of the packaging material by the affixing machine, thereby achieving fixation between the packaging material and the mattress;

[0026] Specifically, a positioning plate is provided to press the passed adhesive tape against the positioning wheel so that the adhesive tape is always in close contact with the positioning wheel. When the positioning wheel presses against the packaging material on the end surface of the mattress, the adhesive tape is attached to the packaging material. Under the rolling of the positioning wheel, the packaging material is attached from bottom to top. After the attachment is completed, the cutting drive source drives the cutting knife forward to cut the adhesive tape, completing the attachment process.

[0027] The sticker machine can also be provided with auxiliary wheels, which are rotatably arranged on the frame and located below the cutting knife; by providing the auxiliary wheels, during the adhesive tape pasting process, the auxiliary wheels are used to roll the newly pasted adhesive tape, thereby improving the degree of adhesion between the adhesive tape and the packaging material.

[0028] Furthermore, the positioning device includes a plurality of positioning columns; the positioning columns are slidably arranged on the conveying platform.

[0029] The beneficial effect of adopting the above further solution is that when the conveying platform conveys the mattress, the positioning column is raised upward to block the mattress, thereby moving the mattress to a designated position for wrapping and gluing of the packaging material.

[0030] Furthermore, the width of the conveying platform is smaller than the width of the mattress; extension plates are provided on both sides of the conveying platform; and a pressing mechanism is also included; the pressing mechanism is correspondingly arranged above the extension plates and presses the mattress together with the extension plates.

[0031] The beneficial effect of adopting the above further solution is that the width of the conveying platform is smaller than the width of the mattress, so that the four corners of the mattress can be completely exposed on both sides of the conveying platform, thereby facilitating the wrapping device and the gluing device to package it.

[0032] Furthermore, there are four groups of covering devices and eight groups of sticker machines; each corner of the mattress is correspondingly provided with a group of covering devices and two groups of sticker machines; there are two mobile racks, each of which is correspondingly provided with two groups of covering devices and four sticker machines, which are used to package the two corner guards on the same side of the mattress.

[0068] The working process of this embodiment:

[0069] Mattress positioning principle:

[0070] The mattress is placed on the conveying platform 10, and the front positioning post 21 is raised by the motor. Then, the conveying platform 10 drives the mattress forward until the front end of the mattress touches the front positioning post 21. At this time, the two corners of the front end of the mattress are positioned, and the two corners of the front end of the mattress are automatically packaged with corner protection by the corresponding covering device 30 and gluing device 40;

[0071] After the two front corners of the mattress are packaged, the rear positioning posts 21 are raised and the mattress is driven backward by the conveying platform 10 until the rear end of the mattress touches the rear positioning posts 21. At this time, the two rear corners of the mattress are positioned, and the corresponding covering device 30 and gluing device 40 are used to automatically package the two rear corners of the mattress.

[0072] After the automatic packaging is completed, all the positioning posts 21 are lowered to make the surface of the conveying platform 10 flat, and then the mattress is conveyed to the output end through the conveying platform 10.

[0073] Working principle of mobile rack 52:

[0074] By setting up the movable frame 52, during the mattress positioning process, the movable frame 52 is away from the mattress to prevent the equipment parts on the movable frame 52 from interfering with the mattress; after the mattress is positioned, the movable frame 52 is driven close to the mattress by the mobile driving mechanism 53, and the corresponding covering device 30 is located outside the corner of the mattress. At this time, a sticker machine is respectively provided on the two sides of a mattress corner.

[0075] Working principles of the feeding device 60, the covering device 30 and the fixing mechanism 36:

[0076] refer to Figure 7The first pressing plate 31 of the wrapping device 30 can be in a horizontal state and located at the output end of the second conveyor roller group. By providing the loading device 60, the rolled packaging material 1 can pass through the first conveyor roller group and the second conveyor roller group and be automatically transported to the first pressing plate 31. The packaging material 1 is then cut by the cutter mechanism 68 to a suitable length. The driving mechanism and the first pressing plate 31 are then turned over to wrap the cut packaging material 1 on the corner of the mattress, thereby realizing fully automated corner protection packaging.

[0077] Specifically, the packaging material 1 passes from the feeding roller 61 between the two first rollers 62 and between the two second rollers 63 in sequence, and then reaches between the first pressure plate 31 and the guide plate 69. The guide plate 69 is provided with an upwardly inclined guide portion 691 on the side close to the second conveying roller group, so as to facilitate the conveying of the packaging material 1 between the first pressure plate 31 and the guide plate 69; the two first rollers 62 are arranged vertically, and the two second rollers 63 are also arranged vertically. The two first rollers 62 and the two second rollers 63 are arranged horizontally adjacent to each other; the roller motor 66 drives the active pulley 67 and the two driven pulleys 65 to rotate, thereby causing the first conveying roller group and the second conveying roller group to convey in the same direction and ensuring that the packaging material 1 is output from the first conveying roller group to the second conveying roller group; when the packaging material 1 is conveyed between the first pressure plate 31 and the guide plate 69, the cutting knife 681 cuts the packaging material 1 between the first roller 62 and the second roller 63;

[0078] After the cutting operation is completed, the first roller 62 and the second roller 63 continue to rotate at a certain angle and convey the cut packaging material 1 forward a little; at this time, one end of the cut packaging material 1 is located on the first pressing plate 31, and the other end of the cut packaging material 1 is located outside the first pressing plate 31 and close to the position of the pushing drive mechanism; then, the fixed driving source 361 drives the steel needle 362 to pierce the packaging material 1 and fix the packaging material 1 on the first pressing plate 31, preventing the packaging material 1 from falling during the turning of the first pressing plate 31;

[0079] refer to Figure 8 , and then, driven by the cylinder or motor, the flip seat 33 slides on the moving frame 52, and drives the packaging material 1 to move to the corner position of the mattress, so that the covering device 30 forms an upright state;

[0080] Then, the turning cylinder 34 of the turning drive mechanism drives the first pressing plate 31 and one end of the packaging material 1 to press toward one side of the corner of the mattress. At the same time, the fixed driving source 361 drives the steel needle 362 to retract, so that the steel needle 362 is separated from the packaging material 1.

[0081] Then, the second pressing plate 32 is driven to move by the pushing drive mechanism, so that the other end of the packaging material 1 is bent and wrapped around the other side of the corner of the mattress; since the corner of the mattress is generally 90 degrees, the movement direction of the second pressing plate 32 is set perpendicular to the surface of the first pressing plate 31, so that when the pushing drive mechanism pushes the second pressing plate 32, the packaging material 1 can be bent into 90 degrees.

[0082] Working principle of gluing device 40:

[0083] After the packaging material 1 is pressed toward the two sides of the corner of the mattress by the first pressing plate 31 and the second pressing plate 32, a certain length of the packaging material 1 is reserved outside the edges of the first pressing plate 31 and the second pressing plate 32. The packaging material 1 is automatically affixed to the reserved length of the packaging material 1 by the affixing machine on the two sides outside the corner of the mattress, thereby achieving fixation between the packaging material 1 and the mattress; the affixing machine moves from bottom to top under the drive of a motor or a cylinder to affix the packaging material;

[0084] Specifically, a tape roll is provided on the tape roller 42, and the tape passes in sequence between the positioning wheel 43 and the positioning plate 44, one side of the cutting knife 45, and the auxiliary wheel 47; as the sticker machine moves from bottom to top, the positioning wheel 43 follows the frame 41 to move upward, and the sticker is pasted on the mattress and packaging material 1 under the drive of the positioning wheel 43. When the positioning wheel 43 rises to the top of the mattress, the cutting knife 45 is driven forward by the cutting drive source to cut the tape, completing the pasting process; and by providing the auxiliary wheel 47, during the adhesive tape pasting process, the auxiliary wheel 47 is used to roll the newly pasted adhesive tape to improve the degree of adhesion between the adhesive tape and the packaging material 1.

[0085] Compared with the prior art, the present invention provides a covering device to automatically cover the packaging material on the corners of the mattress, and automatically fixes the packaging material on the mattress through a gluing device. The present invention has a compact structure and reduces packaging costs.

[0086] In addition, the present invention also has the following beneficial effects:

[0087] By setting up a fixing mechanism, after placing the packaging material on the first pressing plate, the packaging material can be punctured by a steel needle and fixed on the first pressing plate to prevent the packaging material from falling during the flipping of the first pressing plate; the fixing mechanism is preferably a V-shaped needle suction cup, that is, the fixed driving source and the steel needle are arranged in a V-shaped distribution, which can better puncture and fix the packaging material;

[0088] By setting up a loading device, the rolled packaging material can be automatically transported to the first pressing plate, and then the packaging material is cut by the cutter mechanism to make the packaging material cut into a suitable length. Then, the flipping drive mechanism and the first pressing plate can wrap the cut packaging material on the corner of the mattress, realizing full automation of corner protection packaging.

[0089] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
