Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A pocketed spring manufacturing apparatus according to an embodiment of the present invention includes a spring coiler (not shown) capable of making a spring wire into a helical spring, and a spring conveyor capable of receiving the helical spring from the spring coiler and conveying the spring. As shown in fig. 1, the spring conveying apparatus includes a spring bagging conveying device 100 and a spring transfer conveying device 200, the spring transfer conveying device 200 receives a spiral spring 300 from a spring coiling machine and conveys the spring 300 to the spring bagging conveying device 100, and the spring bagging conveying device 100 receives the spring conveyed by the spring transfer conveying device 200 and conveys the spring to a subsequent bag sealing mechanism (not shown) for packaging and welding to form a spring string. Here, the conveying direction of the spring 300 in the spring bagging conveying device 100 is a direction from the rear to the front as shown in fig. 1, and a lateral direction orthogonal to the conveying direction of the spring 300 is a left-right direction as shown in fig. 1.

In the description of the present invention, it is to be understood that the terms "front", "back", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 and 3, the spring transfer conveyor 200 includes a third endless conveyor belt 201, a plurality of conveying seats 202 for positioning the springs 300 are provided on an outer circumferential surface of the third endless conveyor belt 201, and the plurality of conveying seats 202 are uniformly spaced along a circumferential direction of the third endless conveyor belt 201. It is to be understood that the present invention is not limited to use with conveyor belts, for example, the spring-loaded conveyor 200 may be used with conveyor chains or conveyor wheels, as may be determined by one skilled in the art as the need arises. Here, it is understood that "annular", for example, racetrack-shaped. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specified otherwise.

Specifically, the conveying bases 202 are provided with first magnetic members capable of adsorbing springs, each conveying base 202 can adsorb one spring 300 transferred by a spring coiling machine, and conveying is completed under the action of the endless conveying belt 201. The magnetic adsorption mode is adopted, the structure is simple, and the transfer from the spring coiling machine and the transfer from the spring transfer conveying device 200 to the spring bagging conveying device 100 are simple and convenient. Further, the top surface of the conveying seat 202 is a curved surface adapted to the outer contour of the spring 300 and concaved toward the third endless conveyor belt 201, in other words, the bottom surface of the conveying seat 202 is connected to the outer circumferential surface of the third endless conveyor belt 201, the top surface of the conveying seat 202 is designed to be a surface curved toward the bottom surface of the conveying seat 202, and the curved surface is adapted to the outer contour of the spring 300 so as to fix the spring 300 on the conveying seat 202.

As shown in fig. 1 to 4, the spring bagging conveying device 100 includes a first rear endless conveyor belt 1, a second rear endless conveyor belt 2, a first front endless conveyor belt 3, and a second front endless conveyor belt 4, the first front endless conveyor belt 3 and the second front endless conveyor belt 4 are disposed opposite to each other and spaced apart to form a front spring conveying passage 51 between the first front endless conveyor belt 3 and the second front endless conveyor belt 4, the first rear endless conveyor belt 1 and the second rear endless conveyor belt 2 are disposed opposite to each other and spaced apart to form a rear spring conveying passage 52 between the first rear endless conveyor belt 1 and the second rear endless conveyor belt 2, the front spring conveying passage 51 and the rear spring conveying passage 52 communicate in the conveying direction of the springs 300, in other words, the front spring conveying passage 51 is located downstream of the rear spring conveying passage 52 in the conveying direction of the springs 300 and communicates with the rear spring conveying passage 52, the front spring conveying channel 51 and the rear spring conveying channel 52 jointly form a spring conveying channel 5 extending along the conveying direction of the springs 300, no baffle is arranged in the first rear annular conveying belt 1 and the second rear annular conveying belt 2, and the width of the rear spring conveying channel 52 is gradually reduced along the conveying direction of the springs 300.

It is to be understood that the width of the rear spring conveying path 52 is the width in the lateral direction orthogonal to the conveying direction of the springs 300, and the width of the rear spring conveying path 52 in the lateral direction is the distance between the first rear endless conveyor belt 1 and the second rear endless conveyor belt 2 in the lateral direction, and the distance between the first rear endless conveyor belt 1 and the second rear endless conveyor belt 2 in the lateral direction is gradually reduced along the conveying direction of the springs 300.

Here, the first rear endless conveyor belt 1 and the second rear endless conveyor belt 2 are not provided with a baffle, which means that the first rear endless conveyor belt 1 and the second rear endless conveyor belt 2 are not provided around the baffle, so that in the process of gradually compressing and conveying the spring, sliding friction between the first rear endless conveyor belt and the baffle and abrasion of the first rear endless conveyor belt 1 and the second rear endless conveyor belt 2 and the baffle due to sliding friction cannot occur. In addition, since no baffle is provided, the side of the first rear endless conveyor belt 1 and the second rear endless conveyor belt 2 where the springs are held can be deformed inward, thereby providing cushioning for the springs to allow the springs to be gradually compressed and conveyed by a certain amount of axial extension, whereby the springs are not easily arched. Therefore, in the present invention, the first rear endless conveyor belt 1 and the second rear endless conveyor belt 2 may also be referred to as "endless conveyor belts without baffles".

In contrast to the "endless conveyor belt without a baffle" in the present invention, if a support member is provided in the endless conveyor belt in addition to the pulley for supporting the conveyor belt, the conveyor belt slides relative to the support member during the gradual compression and conveyance of the spring, and the endless conveyor belt may be referred to as a "baffled endless conveyor belt". In other words, the endless conveyor belt is called a "baffled endless conveyor belt" as long as the conveyor belt is provided with components that generate sliding friction with the conveyor belt and prevent the springs from axially expanding and deforming during the gradual compression and conveyance of the springs. Of course, the shield is to be understood in a broad sense here, for example comprising a ring-shaped plate, or one or more straight plates, which may also be part of the frame. For example, the conveyor belt disclosed in document CN103879604A is disposed around a baffle, i.e., a baffle is disposed in the conveyor belt, and the conveyor belt is a "baffled endless conveyor belt".

Further, the included angle between the first rear endless conveyor belt 1 and the second rear endless conveyor belt 2 is adjustable. It can be understood that the spring bagging conveying device can be suitable for springs of different types by adjusting the included angle, and the applicability of the spring bagging conveying device is improved.

The spring transfer conveyor 200 is disposed above the spring conveying path 5 to convey the springs 300 into the spring conveying path 5. More specifically, as shown in fig. 1 and 3, the third endless conveyor belt 201 of the spring transfer conveyor 200 has a straight section which is located in the spring conveying path 5 of the spring bagging conveyor 100, and when the third endless conveyor belt 201 runs, the springs 300 on the straight section of the third endless conveyor belt 201 move and are compressed in the rear spring conveying path 52 of the spring bagging conveyor 100.

Further, as shown in fig. 1, 2 and 4, a second magnetic member 61 is disposed in the first front endless conveyor belt 3, a third magnetic member 62 is disposed in the second front endless conveyor belt 4, the second magnetic member 61 is disposed on a side adjacent to the second front endless conveyor belt 4, and the third magnetic member 62 is disposed on a side adjacent to the first front endless conveyor belt 3, in other words, a magnetic member 6 is disposed at a front section of the spring bagging conveyor 100, the magnetic member 6 includes the second magnetic member 61 disposed in the first front endless conveyor belt 3 and the third magnetic member 62 disposed in the second front endless conveyor belt 4, the spring is compressed in the rear spring conveying passage 52, when the spring 300 is compressed to a certain degree, the spring 300 enters the front spring conveying passage 51, the second magnetic member 61 can attract a first end of the spring 300 in the transverse direction, the third magnetic member 62 can attract a second end of the spring 300 in the transverse direction, so that the magnetic force of the second and third magnetic members 61 and 62 on the spring 300 overcomes the attractive force of the first magnetic member on the delivery seat 202 on the spring 300 to disengage the spring 300 from the spring transfer conveyor 200 in the front spring conveying passage 51, and the disengaged spring 300 is continuously conveyed by the spring bagging conveyor 100, whereby the disengaged position of the spring 300 and the spring transfer conveyor 200 can be easily determined by the second and third magnetic members 61 and 62.

Further, both the outer peripheral surface of the first endless conveyor belt 1 and the outer peripheral surface of the second endless conveyor belt 2 are rough surfaces. Here, the "rough surface" may be understood as a state in which the outer circumferential surface of the endless conveyor belt 1 is provided with a plurality of protrusions to increase friction and even to be able to catch the ends of the springs 300, and the shape of the protrusions is not limited, and it may be understood that the protrusions extend from the outer circumferential surface of the endless conveyor belt to the outside of the endless conveyor belt. Here, the outer peripheral surface of the endless conveyor belt refers to the outer side surface of the endless conveyor belt, so that the portion of the outer peripheral surface of the first rear endless conveyor belt 1 located inside the rear spring conveying path 52 and the portion of the outer peripheral surface of the second rear endless conveyor belt 2 located inside the rear spring conveying path 52 are opposed to each other to sandwich the springs therebetween for conveying. The outer peripheral surface of the endless conveyor belt means the outer side surface of the endless conveyor belt so that the portion of the outer peripheral surface of the first front endless conveyor belt 3 located in the front spring conveying path 51 and the portion of the outer peripheral surface of the second front endless conveyor belt 4 located in the front spring conveying path 51 face each other to sandwich the springs therebetween for conveyance. It can be appreciated that the spring conveyor apparatus of the embodiments of the present invention has advantages over chains using endless conveyor belts: the conveying belt is not easy to slip, the outer peripheral surface of the conveying belt can be a rough surface, and even if the chain is provided with the protrusions or the hooks, the spring is not easy to slip in the conveying direction, but is easy to slip in the vertical direction.

According to the spring conveying equipment provided by the embodiment of the invention, the first rear annular conveying belt and the second rear annular conveying belt are not arranged around the baffle plate, so that in the process of gradually compressing and conveying the springs, when the two rear annular conveying belts clamp the springs and compress the springs, the annular conveying belts can provide buffer for the springs to allow the springs to be gradually compressed and conveyed to axially extend for a certain amount, and the springs are not easy to arch; in addition, the sliding friction between the annular conveying belt and the baffle plate can not occur, so that the annular conveying belt and the baffle plate are abraded, therefore, the spring conveying equipment solves the problem that the spring is easy to arch when the spring is compressed, the conveying reliability is improved, the service life of the annular conveying belt is prolonged, the cost is reduced, and the applicability and the production efficiency are improved.

In some embodiments, as shown in fig. 1 and 2, the width of the front spring conveying path 51 in the transverse direction is consistent in the conveying direction of the springs 300, and since the width of the rear spring conveying path 52 in the transverse direction is gradually reduced in the conveying direction of the springs 300, the width of the spring conveying path 5 in the transverse direction is gradually reduced and then kept constant in the conveying direction of the springs 300, so that the springs 300 are gradually compressed in the rear spring conveying path 52 and are continuously conveyed in the front spring conveying path 51.

By providing the baffle 7 in the endless conveyor at the position where the spring 300 is disengaged and conveyed, the conveying reliability can be further improved. It is to be understood that the second magnetic member 61 is provided on the side of the shutter 7 in the first front endless conveyor belt 3 adjacent to the second front endless conveyor belt 4, i.e., on the side of the shutter 7 facing the front spring conveying passage 51, and the third magnetic member 62 is provided on the side of the shutter 7 in the second front endless conveyor belt 4 adjacent to the first front endless conveyor belt 3, i.e., on the side of the shutter 7 facing the front spring conveying passage 51.
