Description

Technical Field

[0001] The utility model relates to the technical field of mattress production, in particular to a bed core positioning and lifting mechanism. Background Art

[0002] Spring mattresses are becoming more and more popular due to their comfort, but the edges of spring mattress cores are prone to deformation and collapse. In order to improve the stability of the mattress core, a metal frame is usually used to fix it on the periphery. At present, the frame of the spring mattress core is basically fixed manually by using a handheld nail gun to fix the frame and the edge of the spring string, or manually positioning and preliminarily fixing the frame, and then fixing it through a nailing process, which has a low degree of automation.

[0003] When nailing the butterfly spring to the side of the bed core, the bottom of the bed core is on the conveyor line, which is not convenient for the operation of the nailing robot, and the bed core position needs to be ensured to be stable during the nailing process. Utility Model Content

[0004] In order to overcome the above shortcomings, the purpose of the utility model is to provide a bed core positioning and lifting mechanism.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a bed core positioning and lifting mechanism, including: a conveying member for conveying the bed core, a truss is arranged above the conveying member, and a positioning member is installed on the truss; the positioning member includes a group of positioning molds one and a group of positioning molds two, a group of positioning molds one is arranged along the first direction, and a group of positioning molds two is arranged along the second direction; a group of positioning molds one and a group of positioning molds two can move relative to or away from each other to adjust the clamping and positioning of the bed core; a lifting member, the lifting member can lift the bed core from the conveying member and then push it to the positioning member. By arranging a lifting member under the bed core, the bed core is lifted to a position suitable for nailing processing, avoiding collision with the conveying member during nailing, thereby improving processing efficiency. By arranging a positioning member above the bed core, when nailing the side of the bed core, it plays a role in fixing the bed core, avoiding nailing misalignment, and further ensuring the stability of the bed core position.

[0006] Furthermore, the conveying member includes two roller conveyors, which are arranged at intervals along the second direction, and the interval distance is smaller than the width of the bed core along the second direction. Two conveyors are arranged to convey the bed core. On the one hand, the interval between the two conveyors can be adjusted to adapt to bed cores of different widths, which is more practical.

[0007] Furthermore, the roller conveyor includes an active roller and a passive roller, which are arranged one by one at intervals. The active roller has a driving device, and the passive roller does not have a driving device. The driving device only drives the active roller to rotate.

[0008] Furthermore, the width of the lifting member along the second direction is smaller than the spacing between the two roller conveyors along the second direction, and the spacing between the two roller conveyors is slightly larger than the width of the lifting member to facilitate the up and down movement of the lifting member.

[0009] Furthermore, the lifting member includes a base, a lifting plate and a scissors fork assembly. One side of the scissors fork assembly is a fixed end, and the other side is a sliding end. The scissors fork assembly is symmetrically arranged on both sides, which supports and balances the bed core and improves the stability of the bed core processing.

[0010] Furthermore, the upper and lower ends of the fixed end are respectively hinged on the lifting plate and the base through hinge seats, and the upper and lower ends of the sliding end are respectively provided with an upper sliding guide device and a lower sliding guide device. The upper sliding guide device and the lower sliding guide device also have a limiting function to ensure that after lifting, the upper and lower sliding ends of the bed core will not slide during the nailing process, and the lifting will be kept stable.

[0011] Furthermore, the scissor fork assembly includes two cross-connected lifting rods, which are rotatably connected by a pin shaft, thereby ensuring stability during the lifting process, stably supporting the lifting frame above, and thereby ensuring stability of the upper bed core processing.

[0012] Furthermore, both the positioning mold 1 and the positioning mold 2 include a base plate 1 and a push plate 1, the base plate 1 is fixed on the truss, the push plate 1 is connected to the base plate 1 through a slide rail, and also includes a driving source 1, which can push the push plate 1 to move relative to the base plate 1.

[0013] Furthermore, positioning mold 1 and positioning mold 2 also include base plate 2 and push plate 2, base plate 2 is fixed at the end of base plate 1, push plate 2 is connected to base plate 2 through a slide rail, and also includes driving source 2, driving source 2 can push push plate 2 to move relative to base plate 2.

[0014] Furthermore, the positioning mold 2 also includes a lower push plate, which is connected to the bottom of the push plate 2 and is connected to the push plate 2 in an "L" shape, used to abut the bed core, increase the positioning area of ​​the push plate 2 on the bed core, and increase its positioning stability.

[0016] 1. By arranging a lifting piece under the bed core, the bed core can be lifted to a position suitable for nailing processing, avoiding collision with the conveying piece during nailing, thereby improving processing efficiency.

[0017] 2. By setting a positioning piece above the bed core, when nailing the side of the bed core, it can fix the bed core, avoid misalignment of nailing, and further ensure the stability of the bed core position.

[0018] 3. Two conveyors are set up to transport the bed core. On the one hand, the distance between the two conveyors can be adjusted to accommodate bed cores of different widths, which is more practical; on the other hand, it is also convenient to set a lifting piece between the two conveyors to lift the bed core, thereby completing the nailing operation on the side of the bed core. The rollers of the two conveyors do not need to be very long, and are shorter than those on one conveyor, which saves more materials. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0029] See attached Figure 1 As shown, a bed core 2 positioning and lifting mechanism in this embodiment includes: a conveying member 1 for conveying the bed core 2, a truss 3 is arranged above the conveying member 1, and a positioning member 4 is installed on the truss 3; the positioning member 4 includes a group of positioning molds 1 41 and a group of positioning molds 2 42, the group of positioning molds 1 41 is arranged along the X direction, and the group of positioning molds 2 42 is arranged along the Y direction; the group of positioning molds 1 41 and the group of positioning molds 2 42 can move relative to or away from each other to adjust the clamping and positioning of the bed core 2; a lifting member 5, the lifting member 5 is arranged directly below the positioning member 4, and can pass through the conveying member 1 to lift the bed core 2 from the conveying member 1 and then reach the positioning member 4. By arranging the lifting member 5 below the bed core 2, the bed core 2 is lifted to a position suitable for nailing processing, avoiding collision with the conveying member 1 during nailing, thereby improving processing efficiency. By arranging the positioning member 4 above the bed core 2, when nailing is performed on the side of the bed core 2, the bed core 2 is fixed to avoid nailing misalignment, thereby further ensuring the stability of the position of the bed core 2.

[0030] See attached Figure 2 As shown, in some embodiments, the conveying member 1 includes two roller conveyors, which are spaced apart along the Y direction, and the spacing distance is smaller than the width of the bed core 2 along the Y direction. Setting two conveyors to convey the bed core 2 can, on the one hand, adjust the spacing between the two conveyors to adapt to bed cores 2 of different widths, which is more practical; on the other hand, it is also convenient to set a lifting member 5 between the two conveyors to lift the bed core 2, thereby completing the nailing operation on the side of the bed core 2. The rollers of the two conveyors do not need to be very long, and are shorter than the rollers on one conveyor, which saves more materials.

[0031] In some embodiments, the roller conveyor includes an active roller and a passive roller, and the active roller and the passive roller are arranged one by one. The active roller has a driving device, and the passive roller does not have a driving device. The driving device only drives the active roller to rotate. This method is suitable for the bed core 2. Since the bed core 2 is large in size and will span several rollers, at least one active roller will definitely be able to drive the material, and the passive roller plays a supporting role. Reducing the number of driven rollers can simplify energy.

[0032] See attached Figure 2 As shown, in some embodiments, the width of the lifting member 5 along the Y direction is smaller than the distance between the two roller conveyors along the Y direction. After the bed core 2 is transported to the processing position by the conveyor, it needs to be lifted to the positioning member 4 by the lifting member 5. Therefore, the distance between the two roller conveyors should be slightly larger than the width of the lifting member 5 to facilitate the up and down movement of the lifting member 5.

[0033] See attached Figure 3As shown, in some embodiments, the lifting member 5 includes a base 51, a lifting plate 52 and a scissor fork assembly 53, one side of the scissor fork assembly 53 is a fixed end 531, and the other side is a sliding end 532. During the lifting process, the fixed end 531 remains in the same position, and as the bed core 2 is lifted up, the sliding end 532 gradually approaches the fixed end 531. The scissor fork assembly 53 is symmetrically arranged on both sides, which supports and balances the bed core 2, thereby improving the stability of the bed core 2 processing.

[0034] See attached Figure 4 As shown, in some embodiments, the upper and lower ends of the fixed end 531 are respectively hinged to the lifting plate 52 and the base 51 through a hinge seat, and the upper and lower ends of the sliding end 532 are respectively provided with an upper sliding guide device and a lower sliding guide device. The upper sliding guide device and the lower sliding guide device also have a limiting function to ensure that after lifting, the upper and lower sliding ends of the bed core 2 will not slide during the nailing process, and the lifting is always stable. A driving rod 535 is also provided on the sliding lower end, and the driving rod 535 can be connected to a reciprocating driving member such as a telescopic cylinder 415.

[0035] In some embodiments, the scissors fork assembly 53 includes two cross-connected lifting rods 534, and the lifting rods 534 are rotatably connected to each other via a pin shaft 533. The two lifting rods 534 are rotatably connected to each other via a pin shaft 533, forming a cross-connection structure shaped like scissors. This structure can ensure stability during the lifting process, stably support the lifting frame above, and thereby ensure the stability of the processing of the upper bed core 2.

[0036] See attached Figure 5 To Attachment Figure 7As shown, in some embodiments, the positioning mold 1 41 and the positioning mold 2 42 both include a bottom plate 1 411 and a push plate 1 412, the bottom plate 1 411 is fixed on the truss 3, the push plate 1 412 is connected to the bottom plate 1 411 through a slide rail 417, and also include a driving source 1. In some embodiments, the driving source 1 is a telescopic cylinder 1 4151, one end of the telescopic cylinder 1 4151 is connected to the push plate 1 412, and the other end is fixed to the truss 3, and the telescopic cylinder 1 4151 can push the push plate 1 412 to move relative to the bottom plate 1 411. The positioning mold 1 41 is set in the direction of conveying the bed core 2. After the bed core 2 is conveyed to the processing position, the push plate 1 412 will gradually approach the bottom plate 1 411 and abut against the side of the bed core 2 under the action of the telescopic cylinder 1 4151. The second positioning mold 42 is arranged in the width direction of the bed core 2, and the spacing between a group of positioning molds 42 is adjusted according to the width of the bed core 2, so as to better position the bed core 2. In other possible implementations, the driving source 1 can also be a motor, and the push plate 1 412 is driven to move through a screw rod coaxially connected thereto.

[0037] In some embodiments, the positioning mold 1 41 and the positioning mold 2 42 further include a bottom plate 2 413 and a push plate 2 414, wherein the bottom plate 2 413 is fixed to the end of the push plate 1 412, and the push plate 2 414 is connected to the bottom plate 2 413 via a slide rail 417, and further include a telescopic cylinder 2 4152, wherein one end of the telescopic cylinder 2 4152 is connected to the push plate 2 414, and the other end is fixed to the bottom plate 2 413, and the telescopic cylinder 2 4152 can push the push plate 2 414 to move relative to the bottom plate 2 413. Under the action of the telescopic cylinder 2 4152, the push plate 2 414 moves downward relative to the bottom plate 2 413, and guides the bed core 2. Among them, the push plate 2 414 of the positioning mold 2 42 can abut against the peripheral surface of the bed core 2, thereby cooperating with the lifting member 5 below the bed core 2 to position the bed core 2.

[0038] In some embodiments, the positioning mold 42 may be set only on the front and rear sides along the conveying direction of the bed core. Therefore, during the movement of the bed core, the positioning mold 42 first drives the push plate 414 to retract and avoid the position. After the bed core passes, the push plate 414 is extended. At this time, the push plate 412 is pushed out in the direction of the bed core under the action of the telescopic cylinder 4151, thereby achieving the positioning effect of the bed core. The telescopic cylinder 4152 used to drive the push plate 414 to retract can be set in the area on both sides of the bed core (i.e., the side set along the conveying direction of the bed core), or the cylinder may not be set. It is only necessary to ensure that the effect of clamping and positioning the bed core can be achieved on the side of the bed core.

[0039] See attached Figure 8As shown, in some embodiments, the second positioning mold 42 further includes a lower push plate 416, which is connected to the bottom of the second push plate 414 and is connected to the second push plate 414 in an "L" shape, and is used to abut the bed core 2. In order to reduce the pressure of the second push plate 414 on the bed core 2 and avoid damage to the bed core 2 caused by excessive force, a lower push plate 416 is provided at the lower end of the second push plate 414 of the second positioning mold 42 to increase the positioning area of ​​the second push plate 414 on the bed core 2 and increase its positioning stability.
