Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) (Industrial application field) The present invention relates to an automatic clipping device for a spring, which is used for manufacturing a bead.

(Prior Art) Clipping for fixing a frame and a spring used for a bead is performed manually as shown in FIGS.

That is, C is a mattress spring assembly, 30 is a frame line, 33 is a spring, and 34 is a clip. As shown in FIG. 7 (c), one by one is manually operated by the clipper 35 held by the balancer 36. The clip is securely bent as shown at 34a, and the frame line and the spring are fixed.

(Problems to be Solved by the Invention) However, when the spring and the frame are fixed by the clipper, the spring is clipped to the frame by the operator's hand by the clipper attached to the balancer. As a result, there is a problem in that the work efficiency varies depending on the physical condition of the worker, and a stable work volume cannot be obtained, and the running cost is high due to manual work.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic clipping device for automatically fixing a spring to a frame line without any manual operation and automatically fixing the spring by a machine.

[Configuration of the invention]

(Means for Solving the Problems) The means for solving the technical problem includes a base on which a workpiece formed by arranging a plurality of coil springs so as to form a substantially rectangular shape, A moving means for moving the base, a rotating means for rotating the base, a clipper facing the work at a predetermined position along the moving direction, and an outer edge of the work on the base being moved. An automatic mattress spring clipping device comprising driving means for driving the clipper so that the frame line and each of the coil springs are fixed by a clip supplied to the clipper.

(Operation) In the mattress spring automatic clipping device configured as described above, the frame is fixed to each coil spring by the clip supplied to the clipper in the process of moving the base. When such fixation is completed, the base is rotated by the rotating means, and similarly,
A frame line along the other outer edge indicates that the base is moving
It is fixed to each coil spring. Thus, the fixing of each frame line to the corresponding coil spring is automatically performed.

In this way, all the devices are automatically operated, and the frame lines and the springs can be reliably fixed without variation and quickly.

Example An example will be described below.

M in FIG. 1 is an automatic clipping device consisting of a base and a gate, and a moving device for fixing a mattress spring assembly (hereinafter referred to as "work") to a work receiving base and moving both sides of the work after clipping. It consists of a rotating device that rotates the work at right angles to clip it, and a clipper device that holds two clippers on the gate gate and moves it up, down, left and right to automatically fix the frame line and the spring.

(1) Moving device 1a is a base, 2 is a work receiving body, 3 is a work receiving base, 4 is a ball screw, 5 is a LM side provided on the left and right, 6
Denotes a work positioning boss, and 7 drives the ball screw 4 by a servomotor to move the work receiving base 3 in the EF direction.

The work receiving base 3 has an enlargement / reduction device in the width direction, and as shown in FIG. 5, the work receiving base 3 has 3a, 3b, 3c.
3a and 3c have a structure that can be moved in the width direction as shown in (a) and fixed as shown by the dashed line with the hook 25 as shown in (b).

(2) Rotating device FIGS. 3 and 4 show a rotating device for the work receiving base 3.
Reference numeral 19 denotes a high rotor, reference numeral 20 denotes a column, reference numeral 21 denotes a table turning arm, reference numeral 22 denotes a high rotor turning arm, and the high rotor 19 is provided substantially at the center of a work receiving base on which the work is held as shown in FIG. When the high rotor turning arm 22 rotates 270 ° and the table turning arm rotates 90 °, the work moves at right angles as shown in the HG direction. As shown in FIG. 4, the work receiving base 3 includes a raising spacer 26 and a slide pack 27, and has a free bearing 28 and a rotating bearing 29 below. .

(3) Clipper device Gate type gate 1b crossing the base 1a at right angles in FIG.
8 is a servo motor, 9 is an LM guide, 10 is a ball screw, 11 is a ball screw joint, 12 is a linear motor for moving the clipper, and the up and down of the clipper holding slope on which the clipper 15 is mounted. Move. 14 is the cylinder that triggers the clipper 15, 16 is the continuous clip, 17 is the clip winding holder, 18
Is a holder for the linear motor 12, which can be moved left and right by the ball screw 10. FIG. 6 shows a structure in which the work is inserted into the mouth of the clipper and is supported by a spring 23 which can move up and down and a spring 24 which can be adjusted in the front-rear direction. .

In FIG. 2, (a) is a frame corresponding to the size of the bed, 30 is a single (S), 31 (M) is a semi-double, and 32 (D) is a frame according to the above structure. Shows the size of double, 33 is a coil spring, 33a, 33b, ...
The upper and lower sides of the spring are connected to the helical line 34 and a mattress spring assembly or workpiece W without a frame line is prepared in advance.

Mattress spring ATC W shown in Fig. 2
30 is set, the spring is set on the positioning boss 6 of the work receiving base 3 of the automatic mattress spring clipping device shown in FIG. 1, and the start button is pressed.

The work receiving body 2 runs on the LM guide 5 by the servomotor 7 and the ball screw 4 and moves to the clip start point. The clipper 15 runs on the LM guide 9 by the servomotor 8 and the ball screw 10 to the upper surface of the work. Insert the mouth of the clipper 15 into the line, trigger the clipper 15 with the cylinder 14, and bend the clip. After clipping, the workpiece is moved in the direction F by the linear motor 7 and the ball screw 4, and the clipping operation is repeated.

When the upper surface longitudinal direction is completed, the clipper 15 is lowered to the lower surface side by the linear motor 12 and the work is moved in the direction E, and the clipping operation is repeated to complete the clipping of the upper and lower surfaces in the longitudinal direction. At that position, the rotor is rotated by the high rotor 19 on the work receiving main body 2 to perform clipping in the width direction in the same manner as in the longitudinal direction.

When the width direction is completed, the high rotor 19 is again rotated to the original state, and the servo motor 7 and the ball screw 4 are used to move to the work take-out position (original position) to complete the automatic clipping. AB and CD in FIG.
Indicates the moving range of the clipper 15, and the two clippers are simultaneously operated by a control device (not shown).

〔The invention's effect〕

The present invention has the following effects. In other words, in the case where the frame line and the spring are fixed to each other manually by a conventional method, a single mat is used to pull the spring of about 130 (S) to 150 (D) to the frame line and to trigger the clipper with a finger. Occupational diseases such as arthritis may occur due to the sticking. In contrast, if the automatic clipping device of the present invention is used, all of the clippings are performed by a machine, so that the occurrence of the occupational diseases may occur. There is nothing.
