Description
Technical Field
The utility model relates to a technical field is made to the spring in bags, more specifically relates to a spring in bags production facility.
Background
Pocketed springs, also commonly referred to as spring strings, are widely used for producing spring cores for mattresses and sofas, the spring strings having a plurality of springs, which are respectively located in pocket chambers of a spring pocket that are spaced apart from each other. In the production of springs using pocket spring production equipment, a spring coiling machine produces individual springs from wire, and then springs are transferred from the spring coiling machine to a spring pocket conveying mechanism by a spring transfer conveying mechanism, which conveys the springs into pockets and welds the pockets to encapsulate the springs, thereby producing a string of springs. In this process, the springs need to be reliably disengaged from the spring transfer conveyor and then received and conveyed by the spring bagging conveyor. In the related art, the spring is not reliably separated from the spring transfer conveying mechanism, and the separation position is difficult to determine.
SUMMERY OF THE UTILITY MODEL
The present application is made based on the discovery and recognition by the inventors of the following facts and problems existing in the related art:
document CN103879604A discloses a bagged spring production compression conveying mechanism, which includes a spring conveying mechanism and a spring compression conveying mechanism, wherein the spring conveying mechanism receives a spring from a spring coiling machine and then transfers the spring to the spring compression conveying mechanism, the spring conveying mechanism includes a track-shaped belt body, a magnetic attraction block for attracting the spring is arranged on the belt body, the spring compression conveying mechanism includes two baffles oppositely arranged on a rack, the distance between the two baffles is gradually reduced from the rear end to the front end (conveying direction), and conveying belts are respectively wound around the outer sides of the two baffles for conveying the spring along the conveying direction. Along with the rotation of the belt body of the spring conveying mechanism, the springs adsorbed on the spring conveying mechanism enter between the two baffles and are conveyed along the conveying direction by the belt body, the distance between the two baffles is gradually reduced along the conveying direction, so the springs are gradually compressed by the two baffles, and when the springs are compressed to a certain degree, namely the friction force between the springs and the conveying belt is greater than the holding force of the magnetic adsorption blocks to the springs, the springs are separated from the spring transfer conveying mechanism and are conveyed continuously along the conveying direction between the two baffles by the conveying belt wound on the two baffles.
The pocket spring production compression conveying mechanism disclosed in the above document has the following problems: the spring is separated from the spring conveying mechanism by means of the friction force between the spring and the conveying belt, namely, the spring can be separated from the spring conveying mechanism only when the friction force between the spring and the conveying belt is larger than the adsorption force of the magnetic adsorption block to the spring. The compression amount of the spring between the two baffles influences the friction force, and only when the compression amount of the spring reaches a certain value, the friction force between the spring and the conveying belt is larger than the adsorption force of the magnetic adsorption block on the spring.
It is known to those skilled in the art that the amount of compression that the springs must be compressed before bagging is a requirement of the mattress core design in order to design the softness and hardness of the mattress core. That is, when designing the mattress core, in order to design the dimensions such as softness and thickness of the mattress core, the model of the spring wire, the length of the hair spring (the spring that is not compressed before bagging produced by the spring coiling machine), the compression amount of the spring and the tension of the bagged spring to the bag need to be designed. In other words, in the production of pocketed springs, the springs must be compressed by a certain amount of compression prior to bagging to meet design requirements. Thus, the amount of compression of the spring prior to bagging is limited by the pocketed spring design, rather than being set arbitrarily.
In the compression conveying mechanism for producing the pocket springs disclosed in the above document, the compression amount of the springs should meet the design requirement of the pocket springs (mattress core) on one hand, and also meet the requirement that the springs can be separated from the spring conveying mechanism on the other hand, that is, the compression amount of the springs is limited by two factors, so that the compression conveying mechanism for producing the pocket springs disclosed in the above document has the problems that the separation of the springs from the spring conveying mechanism is unreliable, the separation position is difficult to determine, and the produced pocket springs cannot meet the design requirement and the separation requirement at the same time.
In other words, in the above document, the compression amount of the spring is required to satisfy not only the requirement that the frictional force between the spring and the conveyor belt is larger than the attraction force of the magnetic attraction block of the spring conveying mechanism to the spring, but also the design requirement of the pocket spring.
It will be appreciated by those skilled in the art that in the above-mentioned document, the spring is compressed the most at the front end where the distance between the two flaps is the smallest, so that the friction between the spring and the conveyor belt is the greatest at the front ends of the two flaps, at least this maximum friction (maximum compression) must be such that the spring will be able to disengage from the spring conveyor mechanism, i.e. the spring must disengage from the spring conveyor mechanism at the latest at the end where the distance between the two flaps is the smallest. Further, this document clearly describes that the spring is separated from the spring conveying mechanism and then conveyed by the conveyor belt outside the shutters, that is, the spring is separated from the spring conveying mechanism before reaching the end where the distance between the shutters is minimum, in other words, the spring must be separated from the spring conveying mechanism before the amount of compression thereof reaches the maximum.
However, in the above-mentioned document, if the spring compression amount required for the pocket spring design is smaller than the maximum compression amount of the spring at the end where the distance between the two baffles is the smallest, the spring compression amount cannot satisfy both the design requirement and the requirement that the spring is separated from the spring conveying mechanism. For example, the maximum compression amount of the spring required by the design of the pocket spring is 10 mm, while the compression amount of the spring is at least 20 mm for separating the spring from the spring conveying mechanism, and if the maximum compression amount of the spring is required to meet the design requirement (the compression amount is less than 10 mm), the separation of the spring from the spring conveying mechanism cannot be realized, whereas if the compression amount is required to meet the requirement for separating the spring from the spring conveying mechanism (the compression amount is at least 20 mm), the design requirement cannot be met.
Moreover, in the above document, since the spring is disengaged from the spring conveying mechanism only by the friction force between the spring and the conveying belt, the disengagement position of the spring between the two baffles is not easy to determine, and particularly, the disengagement position of the spring varies even though the rigidity of the steel wire for manufacturing the spring varies with the variation of the model of the spring.
In addition, the spring is separated from the spring conveying mechanism only by means of friction force between the spring and the conveying belt, the spring is easy to slip from the conveying belt, reliability of separation of the spring and reliability of conveying of the conveying belt to the spring are poor, follow-up bagging is affected, and production efficiency is reduced.
The present invention aims at solving at least one of the technical problems in the related art to a certain extent. Therefore, the utility model provides a spring production facility in bags, the compression capacity of spring can conveniently satisfy and break away from requirement and spring design requirement in bags, and the reliability that the spring breaks away from is high, breaks away from the position and easily confirms, has improved production efficiency.

According to the utility model discloses spring production facility in bags owing to set up the magnetic part, makes the spring break away from switching conveyor through the magnetic part to the adsorption affinity of spring, only need consider the magnetic part to the adsorption affinity of spring and switching conveyor to the holding power between the spring the relation can, need not to consider that the spring breaks away from the restriction to the frictional force between spring and the conveyer belt. In the embodiment of the application, although a certain friction force exists between the spring and the two second conveyor belts, the friction force is naturally caused by the fact that the spring must be compressed before bagging, and although the friction force can assist the spring to be separated from the transfer conveyor device objectively, the relationship between the attraction force of the magnetic member on the spring and the holding force of the transfer conveyor device on the spring can be considered when the spring is separated from the transfer conveyor device. Therefore, the compression amount of the spring between the two second conveying baffle plates only needs to be considered to meet the design requirement of the bagged spring, and the requirement that the spring is separated from the compression amount (the friction force is in positive correlation with the compression amount) does not need to be considered. Through changing the parameter of magnetic part, for example, the magnetism size and the magnetic part number of magnetic part, can conveniently change the adsorption affinity to the spring to change the adsorption affinity of magnetic part to the spring, ensure that the spring can break away from switching conveyor reliably, can guarantee from this that the maximum compression capacity of spring satisfies bagged spring's designing requirement, also can guarantee that spring and switching conveyor break away from reliably, can not influence follow-up bagging-up, improved production efficiency.
