Definitions

  • This invention is an invention that produces the springs, transfers them to the mounting section and ties the springs to each other.
  • the invention produces bed springs, puts them in rows, combines these rows and makes them into spring frames.
  • the springs In the process of forming this frame, before putting the springs in rows, in order for the fabric not to be damaged by the nodes, they must be turned by a certain degree. That is, the nodes of the first and last springs must face towards the inside of the springs.
  • the springs In the invention in Patent No. 5,788,051 the springs are produced, transferred to the transfer section then turned to make them vertical and there is a control mechanism to check the nodes.
  • the mechanism that turns the transfer bands is not efficient and requires many pieces of apparatus for durability. In this invention, this problem is attempted to be solved with a mechanism placed just after the spring production. The spring is made vertical and at the same time it is turned axially during this movement to adjust the location of the nodes.
  • Patent No. 5,570,810 is related with the operation of spring production, spring transfer and spring alignment sections together.
  • the automations in the given reference are implemented in a similar way and, in addition, a system is added that will enable the spring production, transfer and alignment sections, which are the main sections of the invention, to become suitable for the desired spring length.
  • the invention in Patent No.US20080017271 is related with an apparatus that performs the action of turning the spring.
  • the spring is transferred in 3 stages. First, the spring comes from the intermediate metal sheets horizontally and the nodes are turned with the arms between the metal sheets. Then, these horizontally turned springs are placed between plates and they are brought to the vertical position between these plates. This way, the angular adjustment of the spring nodes is made. Then, the springs are pushed to an intermediate transfer band. From this transfer band, they are sent to the alignment section by transferring to another band.
  • This system is very complicated, because the spring goes through too many movements; this may affect the position of the spring and may cause problems in the frame dimensions. Also, as there is more than one transfer section, timing adjustment is difficult and production may be slower due to the same reason. Furthermore, placing the springs on the transfer bands when the transfer band is in motion may disturb the spring position.
  • the invention in Patent No. 3,918,473 is related with a spring transfer apparatus.
  • springs come from a spring production section horizontally.
  • this invention where there is a geared node turning mechanism, the springs coming from the spring machine horizontally are place on the transfer band close together and the springs are turned to the end of the transfer band with a geared apparatus around their axes. This way, the nodes of the springs are turned.
  • the bands are conveyed to alignment the lower diameters of the springs are compressed with an apparatus perpendicular to the band surface and brought to the vertical position with piston mechanisms.
  • One of the problems of this system is this bringing the spring to the vertical position by compressing them.
  • a mechanism is needed to make all the springs vertical and this mechanical system is complicated.
  • Patent No. 6,688,457 B2 is related with a machine including a spring production, carrying and alignment system.
  • springs come from a spring production section horizontally, also.
  • this transfer system instead of carrying between bands, it is done with mechanisms that progress with a chain system between the bands.
  • the springs coming from the spring production system are attached to the clips on the mechanisms in this transfer system.
  • This system is not very practical because the springs may get stuck on these clips, or it may be difficult to remove them from the clips.
  • the step distance between the springs is adjusted by the distance between these mechanisms.
  • another system proposed for the invention in the said patent is the use of a compression band that will be used for removing the springs easily. This system is an extra mechanism.
  • this compression is made from the distance between the bands only and another compression mechanism is not needed due to the height automation.
  • Patent No. 6,688,457 B2 is related with an apparatus that transfers the springs.
  • the springs coming from the spring production section are transferred to a magnetized surface pivoted perpendicular to the band surface. This surface turns around the section it is pivoted and turns the spring attached with magnet 90 degrees to make it vertical. After that, these springs are transferred to a constantly moving band system.
  • This transfer system is not reliable, because the springs placed on a constantly moving band may shift in position.
  • Pins are placed in the inner part of the band to adjust the steps between the springs. These pins operate with solenoids. When the spring makes contact with the transfer band the pin for the next spring operates and rises.
  • a pin system is used that has the same number of solenoids as the number of springs in the set. This system is costly and requires a complicated electrical mechanism.
  • the springs in the transfer section are placed into the alignment section with a pushing system in two stages. In the first stage, the springs are pushed from the bottom part to bring them top preliminary alignment. The second push is made from the top and the springs are placed in the mouths of the molds. Then, the springs are tied together with a spiral that is fed into the alignment section.
  • a similar system is used in this system. Spiral support parts and spiral transition releases are placed inside the molds in which springs are put. This way, a more stable and durable tying is ensured.
  • Patent No. 3,722,056 is related with a machine that positions the nodes.
  • Pushing mechanisms are used for turning the nodes at the upper and lower part of the springs coming to the transfer band horizontally. These mechanisms turn the lower and upper nods of the springs with small turning parts. But, during this turning motion on the transfer band, block mechanisms are used to prevent slipping of the spring.
  • the node adjustment of the spring in this patent is made with a small axial turning before transferring to the band and is much easier to implement.
  • Patent No. 3,631 ,960 is related with a transfer apparatus that transfers the springs horizontally. Springs coming from a known spring production machine horizontally are placed between transfer bands close together. In this system, which advances in steps, this is similar to stepped spring motion. Springs moving between the bands stop after advancing a step and a piston system contacts the spring from below and turns the nodes. After this operation, the springs advance and come to the next piston.
  • the major drawback of this system is that it lacks an apparatus to bring the springs to the vertical position. Therefore, the springs must be brought to the vertical position after this mechanism in another section; this increases the dimensions of the machine. In this invention, on the other hand, springs are brought to the vertical position and their nodes are aligned before they enter the transfer band.
  • Patent No. 3,386,561 is related with a spring frame production machine. Springs are placed on an intermediate metal sheet before they enter the transfer band. There are jaw pieces in this intermediate metal sheet. These jaw pieces push the spring pressed between the intermediate metal sheets upward and place them on the transfer band. After that, the band makes a step motion and opens a space for the next spring.
  • the mechanism includes gear and gear parts to turn the spring nodes, and the nodes are turned before the springs are transferred to the band. Jaws turn the springs by 180 degrees when they carry them to the transfer band.
  • the system has an arm system that takes the springs from the transfer band and transfers them to the alignment section. This mechanism has an arm system in the same number as the springs in the set. These arms take their motion from the piston systems.
  • the arms move with air pressure and lift the plates connected to them. When the air is releases the plates are lowered and catch the spring between the bands. Air is supplied again from another piston and the systems are carried upwards with a cam system. Afterwards, another piston supplies air to the mechanism and brings the spring to the vertical position with a cam way and advances it.
  • This mechanism is not very efficient, because a lot of arm movements are required for the spring to become vertical and as each motion is supplied from a different piston, it takes time. Also, too many mechanisms in the system increase the dimensions of the machine. In the system of this invention, the spring is made vertical without the need for any of these operations and its nodes are turned before being placed on the transfer band.
  • the purpose of the invention in line with claim 1 , is to obtain a spring frame in the desired spring length and in addition to that, to present a new and effective design that has a fast production rate, is durable, has a long service life, is fully automatic, and produces the springs, transfers them, and ties them together with a spiral to produce a spring frame.

Le ressort placé en position verticale est transporté jusqu'à la bande de transfert (20) par le groupe de saisie de ressort (23) dans la section de transfert de ressort (69). Les ressorts transportés sont acheminés jusqu'à la section d'alignement (44) au moyen de la bande de transfert. Les ressorts sont acheminés jusqu'à la section d'alignement (44) par une section de poussée. Puis ils sont regroupés en un ensemble préalable avant d'être transportés jusque dans les paires de moules (96) au moyen d'une partie de languette inférieure (168) et d'une partie de languette supérieure (169). Les diamètres inférieurs (157) et supérieurs (158) des ressorts sont enroulés en une spirale (101) puis attachés aux rangées de ressorts entre les précédentes paires de moules (96). Ce processus permet de former un cadre à ressorts.
