Description

Spring-positioning device and localization method

Technical field

The present invention relates to the sping mattress technical field of processing equipment, especially relate to a kind of spring-positioning device and localization method.

Background technology

Figure 1 shows that the spring 2 for sping mattress, the two ends diameter of spring 2 is greater than the diameter of mid portion, and the two ends of spring 2 respectively have a node 21.The spring of using on mattress is all by the machine standardized production, and the node of each spring is for same position.These springs need to be by forming net of spring bed after wearing the net machine and being connected, net of spring bed is wrapped cloth outward and just formed later on sping mattress.Referring to Fig. 2, these springs 2 need be connected into one through wearing the net machine, wear the net machine when wearing net, need to avoid as far as possible node 21, otherwise the steel wire of wearing net can meet with obstruction.

Encounter the node of spring for the steel wire that prevents from wearing net, the direction of spring node all needs in advance through arranging.Be all the mode by manual alignment, the node that guarantees each spring can not be positioned on the circuit that steel wire passes in the past, and doing like this wastes time and energy, and greatly reduces the production efficiency of sping mattress.

Summary of the invention

The present invention is directed to deficiency of the prior art, a kind of spring-positioning device is provided, retainer spring, guarantee that spring enters when wearing the net machine automatically, and the steel wire of wearing net can not meet with obstruction.

Another object of the present invention is that the localization method of this kind spring-positioning device is provided.

For solving the problems of the technologies described above, the present invention is solved by following technical proposals: spring-positioning device, comprise transmitter, receiver, be used for the fixture of fixing spring and drive the driving mechanism that described fixture is rotated, described spring is fixed on fixture, when described fixture is rotated, there is and only has the node of spring on spring through the line of described transmitter and described receiver.

A kind of localization method of described positioner comprises following steps: 1) described transmitter starts, and sends signal to described receiver; 2) described fixture fixing spring; 3) described driving mechanism drives described fixture rotation, and described spring is also along with fixture is rotated together; When 4) described spring 2 turned to certain angle, described node was positioned on the line of described transmitter and described receiver, and described drive unit drives described fixture again and rotates a predetermined angle.

The invention has the beneficial effects as follows: can automatically complete the location of spring angle, make to be transported to the spring node direction of wearing on the net machine and can not to be positioned on the route that steel wire passes, production efficiency is high, can be according to user's the position that requires automatic adjuster spring.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail: in the present embodiment, plate 104 is defined as the front of plate towards the side of spring 2, plate 104 is defined as the back side in the side of spring 2 dorsad.

Referring to Fig. 3 and Fig. 4, spring-positioning device, comprise base 100, be fixed with pedestal 106 and motor 108 on base 100, be fixed with an end of bar 107 on pedestal 106, be rotatably connected to the plate 104 of a circle on the other end of bar 107, the center of circle of plate 104 is positioned on the axis of bar 107, be fixed with a transmitter 101 on the end face of bar 107, transmitter 101 main parts are a luminous tube.Be fixed with three electromagnet 103 on plate 104, electromagnet 103 and plate 104 are combined the fixture of common composition spring 2.Its operation principle be utilize electromagnet 103 the attraction when electric is adsorbed on spring 2 on plate 104.The back side of plate 104 is provided with the second belt wheel 110.Being connected with the first belt wheel 109, the first belt wheels 109 and the second belt wheel 110 on the output shaft of motor 108 links together by Timing Belt 111.Motor 108, the first belt wheel 109, the second belt wheel 110 and Timing Belt 111 have formed the driving mechanism that drives the fixture rotation jointly.During use, electromagnet 103 gets electric absorption spring 2, makes spring 2 be fixed on plate 104, and then motor 108 drives plates 104 rotations by Timing Belt 111, makes also and then rotation of spring 2.Here adopting Timing Belt rather than general bel-drivenn reason is that toothed belt transmission can guarantee the accuracy of transmission.The front of plate 104 is provided with a charging conduit 105, and charging conduit 105 is used for temporarily depositing spring 2, and two sides of charging conduit 105 vertically arrange, and the distance between two sides equals the diameter at spring 2 two ends.The bottom of charging conduit 105 is provided with a gripper shoe 112, and gripper shoe 112 equals the radius at spring 2 two ends to the distance of plate 104 rotating shafts.It is coaxial with the rotation of plate 104 that the rotation of spring 2 should keep.Transmitter 101 is fixed on the sidewall 113 of charging conduit 105 1 sides.Transmitter 101 emits beam towards receiver 102, the interior light-sensitive material that arranges of receiver 102.The light that transmitter 101 sends should satisfy, and when spring 2 rotates, has and only have node 21 parts on spring 2 through described light.When the node 21 on so each spring 2 passed through light, the position of spring 2 was only definite.

The localization method of spring-positioning device referring to Fig. 5 to Fig. 8, comprises the steps: 1) referring to Fig. 5, transmitter 101 is towards receiver 102 emission of lights (referring to dotted line in Fig. 5), and at this moment receiver 102 can receive the signal that transmitter 101 sends.

2) referring to Fig. 6, spring 2 drops in charging conduit 105, and electromagnet 103 gets electric, and spring 2 absorption are fixed on plate 104.Spring 2 falls to charging conduit 105 when interior, and the position of each spring 2 in charging conduit 105 is arbitrarily.

3) referring to Fig. 7, motor 108 starts, and drives plates 104 by Timing Belt 111 and rotates, and plate 104 rotates and drives springs 2 and rotate, node 21 positions on spring 2 also and then plate 104 rotate together.

4) referring to Fig. 8, when spring 2 turns to certain angle, the light of transmitter 101 emissions is blocked by the node 21 on spring 2, receiver 102 can not receive the light signal that transmitter 101 sends, at this moment the position of spring 2 just has been determined, and then as required, rotating certain angle, this has just completed the location of spring 2.
