A spring compression separation conveying mechanism and its conveying method

Abstract

The present invention discloses a spring compression separation and conveying mechanism, comprising an annular conveying mechanism, a clamping conveying mechanism, a compression plate and a crank. The two compression plates are relatively arranged below the annular conveying mechanism. The crank performs periodic trajectory motion to drive the compression plate to perform circular motion. The two compression plates maintain an unchanged angle. The annular conveying mechanism is provided with a magnetic spring connecting plate. The two compression plates compress and convey the spring to the clamping conveying mechanism. The present invention adopts the annular conveying mechanism and the compression plate to cooperate to separate the spring from the annular conveying mechanism and convey it into the clamping conveying mechanism, thereby ensuring that the spring can be detached from the suction cup and can be compressed to enter the clamping conveying mechanism for output. The present invention also develops a spring conveying method. During the compression and conveying process, the annular conveying mechanism, the clamping conveying mechanism and the compression plate maintain continuous motion without stopping to wait for the compression plate to reset, thereby reducing the time difference of spring compression and conveying, thereby improving production efficiency.

Description

Technical Field

[0001] The present invention relates to the technical field of bagged spring production equipment, and particularly relates to a spring compression, separation and conveying mechanism. Background Art

[0002] A spring bagging machine is a commonly used bagged spring production machine.

[0003] In a common spring bagging machine, before the spring is sent into a cloth bag formed by non-woven fabric, the spring needs to be compressed and then conveyed. At this time, a spring compression and conveying device is required.

[0004] The existing spring compression and conveying device is provided with baffles with gradually decreasing openings at the inlet end of the clamping and conveying mechanism, and a ring-shaped conveying mechanism with suction cups is arranged above the clamping and conveying mechanism and the baffles. The ring-shaped conveying mechanism sends the spring along the baffle into the clamping and conveying mechanism, so as to complete the compression of the spring during the conveying process. However, in this way, it is very easy for the spring to prematurely detach from the suction cup during the conveying process, resulting in the situation that the spring cannot be compressed and conveyed.

[0005] The existing compression and conveying mechanism cannot ensure that the spring can both detach from the suction cup and be compressed and enter the clamping and conveying mechanism for output. Therefore, the present application proposes a new compression and conveying method. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention aims to provide a spring compression, separation and conveying mechanism.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] A spring compression, separation and conveying mechanism includes a ring-shaped conveying mechanism, a clamping and conveying mechanism, compression plates and cranks. The two compression plates are relatively arranged below the ring-shaped conveying mechanism. The cranks make periodic trajectory movements to drive the compression plates to make cyclic movements. The two compression plates keep the included angle unchanged, and the cranks on the two compression plates rotate in opposite directions. Magnetic spring receiving plates are equidistantly arranged on the ring-shaped conveying mechanism. The two compression plates compress and separate the springs on the magnetic spring receiving plates and then convey them into the clamping and conveying mechanism, and the clamping and conveying mechanism clamps and outputs the compressed springs.

[0009] Further, the ring-shaped conveying mechanism is a ring-shaped conveying chain / ring-shaped conveyor belt, and at least one of the ring-shaped conveying mechanism and the compression plates can move up and down.

[0010] Further, the clamping and conveying mechanism is composed of two relatively arranged conveying chains / conveyor belts, and at least one of the two conveyor belts / conveying chains can move relative to the other.

[0011] Further, the minimum distance between the two compression plates is adjustable.

[0012] Further, the minimum distance between the two compression plates is less than or equal to the distance between the two conveyor belts / conveyor chains of the clamping and conveying mechanism.

[0013] Further, the two compression plates are parallel to each other.

[0014] Further, the annular conveying mechanism, the compression plates and the clamping and conveying mechanism are all synchronously conveyed.

[0015] The present invention also discloses a spring conveying method, including the following steps:

[0016] Step 1: The annular conveyor belt continuously conveys the spring from the top to the bottom until the spring enters between the two compression plates, and then enters Step 2.

[0017] Step 2: The crank makes a periodic trajectory movement to drive the two compression plates to move relatively closer to clamp and compress the spring, and at the same time, the two compression plates displace towards the clamping and conveying mechanism. At this time, the annular conveying mechanism keeps conveying, and then enters Step 3.

[0018] Step 3: The annular conveying mechanism keeps the conveying action and the crank keeps the periodic trajectory movement. Since the pressing force of the two compression plates is greater than the suction force of the magnetic receiving tray, the spring is separated from the magnetic receiving tray, and then the compression plates drive the spring into the clamping and conveying mechanism, and then enter Step 4.

[0019] Step 4: The annular conveying mechanism keeps the conveying action and the crank keeps the periodic trajectory movement. After the compression plates clamp the spring and extend into the clamping and conveying mechanism, the two compression plates move away from each other and reset along the trajectory of the crank. During this process, the annular conveying mechanism feeds the spring between the two compression plates.

[0020] The present invention has the following beneficial effects:

[0021] A spring compression, separation and conveying mechanism of the present invention adopts the cooperation of an annular conveying mechanism and a compression plate 3 to separate the spring from the annular conveying mechanism and feed it into the clamping and conveying mechanism, so as to ensure that the spring can not only be separated from the suction cup, but also be compressed and fed into the clamping and conveying mechanism for output; secondly, the crank makes a periodic trajectory movement, so that after the spring is input into the clamping and conveying mechanism, the compression plates can be periodically reset, so that the entire production process does not need to be reset by reverse movement, thereby improving the production efficiency.

[0029] The present invention will be further described below in conjunction with the drawings and specific embodiments, so as to more clearly understand the technical idea required to be protected by the present invention.

[0030] As Figures 1 to 7 shown, a spring compression, separation and conveying mechanism of the present invention includes an annular conveying mechanism 1, a clamping and conveying mechanism 2, a compression plate 3 and a crank 4. The two compression plates 3 are arranged oppositely below the annular conveying mechanism 1. The crank 4 makes a periodic trajectory movement to drive the compression plate 3 to make a cyclic movement. The two compression plates 3 keep the included angle unchanged. The cranks 4 on the two compression plates 3 rotate in opposite directions. The annular conveying mechanism 1 is equidistantly provided with magnetic spring connecting plates 11. The two compression plates 2 compress and convey the springs on the magnetic spring connecting plates 11 into the clamping and conveying mechanism 2, and the clamping and conveying mechanism 2 clamps and outputs the compressed springs.

[0031] It should be noted that in this embodiment, the number of the cranks 4 is two. The two cranks 4 and the compression plate 3 form a double-crank linkage mechanism. In this way, the crank 4 makes a circular motion (circular periodic motion), and the compression plate 3 makes a cyclic motion (moves along the rotation of the crank 4) when the crank 4 makes a circular motion, and the two compression plates 3 keep the included angle unchanged.

[0032] When the present invention is in use, first, the two compression plates 3 are at the starting point (as Figure 5As shown, the ring conveyor mechanism 1 conveys springs one by one until a spring enters between the two compression plates 3. Then, the crank 4 rotates, driving the two compression plates 3 to move along an arc (at this time, the ring conveyor mechanism 1 moves synchronously with the compression plates 3), so that the two compression plates 3 clamp the spring and move it into the clamping conveyor mechanism 2 until a part of the spring clamped by the two compression plates 3 extends into the clamping conveyor mechanism 2 (as Figure 6 shown). At this time, since the clamping force of the spring by the compression plates 3 is greater than the magnetic force from the magnetic spring connecting plate 11, and at the same time, since the magnetic material receiving tray needs to move obliquely upward according to the ring conveyor mechanism 1, the spring separates from the magnetic spring connecting plate 11 and stays in the compression plates 3. Then, the crank 4 continues to rotate, causing the compression plates 3 to release the spring. The two ends of the spring are tightly pressed against both sides of the clamping conveyor mechanism 2, and at the same time, the clamping conveyor mechanism 2 conveys the spring synchronously. The crank 4 continues to rotate until it rotates one week and resets (as Figure 7 shown). In this way, the purpose of separating the spring from the ring conveyor mechanism 1 to the clamping conveyor mechanism 2 is achieved, and the clamping conveyor mechanism 2 outputs the spring while keeping it compressed.

[0033] It should be noted that when the crank 4 rotates to make the compression plates 3 release the spring and reset, specifically: the crank 4 continues to rotate in the same direction, making the compression plates 3 move parallel to the arc of the crank 4 (specifically referring to the double-crank link mechanism with equal length of the crank 4). During the continuous movement, the two compression plates will move from clamping to opening (that is, from relatively close to moving away from each other) until the crank 4 rotates one circle and completes the reset.

[0034] The advantages of the present invention are: 1. The ring conveyor mechanism 1 cooperates with the compression plates 3 to separate the spring from the ring conveyor mechanism 1 and send it into the clamping conveyor mechanism 2, so as to ensure that the spring can not only be separated from the suction cup but also enter the clamping conveyor mechanism for output while being compressed; 2. The crank 4 makes a periodic trajectory movement, so that after the spring is input into the clamping conveyor mechanism 2, the compression plates 3 can be periodically reset, making the entire production process not require reverse movement for reset, thereby improving production efficiency.

[0035] Further, the ring conveyor mechanism 1 is a ring conveyor chain / ring conveyor belt, and at least one of the ring conveyor mechanism 1 and the compression plates 3 can move in the up and down direction.

[0036] More preferably, one of the ring conveyor mechanism 1 and the compression plates 3 can move up and down relative to the other, so as to adapt to springs with different shaft diameters.

[0037] Further, the clamping conveyor mechanism 2 is composed of two relatively arranged conveyor chains / conveyor belts, and at least one of the two conveyor belts / conveyor chains can move relative to the other.

[0038] More specifically, the distance between the two conveyor chains / conveyor belts of the clamping and conveying mechanism 2 is adjustable, so as to be able to adapt to springs of different sizes.

[0039] Furthermore, the minimum distance between the two compression plates 3 is adjustable.

[0040] More preferably, the minimum distance between the two compression plates 3 is adjustable, which is beneficial to compressing springs of different heights and adjusting the compression amount at the same time to ensure that the springs can be disengaged from the magnetic receiving tray 11.

[0041] Furthermore, the minimum distance between the two compression plates 3 is less than or equal to the distance between the two conveyor belts / conveyor chains of the clamping and conveying mechanism 2.

[0042] More specifically, the minimum distance between the compression plates 3 is less than or equal to the distance between the two conveyor belts / conveyor chains of the clamping and conveying mechanism 2, so as to ensure that the compression plates 3 can send the springs into the clamping and conveying mechanism 2 and avoid being unable to send the springs into the clamping and conveying mechanism 2 due to insufficient compression.

[0043] Furthermore, the two compression plates 3 are parallel to each other.

[0044] More preferably, the compression plates 3 are parallel to each other, which can ensure that the forces on both sides of the spring are parallel during the compression process and avoid the spring from coming out to the greatest extent.

[0045] Furthermore, the annular conveying mechanism 1, the compression plates 3 and the clamping and conveying mechanism 2 are all synchronously conveyed.

[0046] More preferably, the synchronous conveyance of the annular conveying mechanism 1, the compression plates 3 and the clamping and conveying mechanism 2 can ensure that when the compression plates 3 compress and separate the springs from the annular conveying mechanism 1, the situation of uneven force on the springs caused by the speed difference and resulting in spring inclination can be avoided.

[0047] It should be noted that the compression plate 2 should also be provided with a structure for avoiding the clamping and conveying mechanism 1, such as a through groove, a passage, etc., or the clamping and conveying mechanism 1 is provided with a structure for avoiding the compression plate 2, such as the middle of a multi-layer structure being hollowed out, etc. This belongs to a common avoidance structure and will not be elaborated here. It is only necessary to ensure that the cyclic movement of the compression plate 2 will not be affected by the clamping and conveying mechanism 1.

[0048] The present invention also discloses a spring conveying method, including the following steps:

[0049] Step 1: The annular conveyor belt 1 continuously conveys the springs from the top to the bottom until the springs enter between the two compression plates 3, and then enter Step 2.

[0050] Step 2: The crank 4 makes a periodic trajectory motion to drive the two compression plates 3 to move relatively closer to clamp and compress the spring, and at the same time, the two compression plates 3 displace towards the clamping and conveying mechanism 2. At this time, the annular conveying mechanism 1 continues to convey, and then enter Step 3.

[0051] Step 3: The annular conveying mechanism 1 continues its conveying action and the crank 4 continues its periodic trajectory motion. Since the pressing force of the two compression plates 3 is greater than the suction force of the magnetic material receiving tray 11, the spring is separated from the magnetic material receiving tray 11, and then the compression plate 3 drives the spring into the clamping and conveying mechanism 2, and then enter Step 4.

[0052] Step 4: The annular conveying mechanism 1 continues its conveying action and the crank 3 continues its periodic trajectory motion. After the compression plate 3 clamps the spring and extends into the clamping and conveying mechanism 2, the two compression plates 3 move away from each other and reset along the trajectory of the crank 4. During this process, the annular conveying mechanism 2 feeds the spring between the two compression plates 3.

[0053] The advantages of the present invention are as follows: During the compression and conveying process of this spring conveying method, the annular conveying mechanism 1, the clamping and conveying mechanism 2, and the compression plate 3 keep moving continuously, without waiting for the compression plate 3 to reset, reducing the time difference of spring compression and conveying, thereby improving the production efficiency.

[0054] For those skilled in the art, according to the technical solutions and concepts described above, various corresponding changes and deformations can be made, and all these changes and deformations should fall within the protection scope of the claims of the present invention.
