In addition, an adhesive application section 18 is fixedly installed between the first operation position A and the second operation position B, a filling portion 21 is installed at the second operation position B, and a reversing section 24 is installed at the third operation position C. . FIG. 3 is a partially cutaway front view of the trolley 1 and the movable base 6, and FIG. 4 is a perspective view of the trolley 1, the movable base 6, and the reversing unit 24 showing another structural example of the trolley 1 and the movable base 6.

The trolley 1 has a support surface 2 on which the spring unit 51 is mounted. The support surface 2 is provided with a large number of grooves 3 extending along the running direction of the trolley 1. The cart 1 has a self-propelled function, reciprocates between a first working position A and a second working position B along a rail or a guide (not shown), and has a first working position A and a third working position C.
Reciprocate along a rail or a guide (not shown).

The carriage 6 has a support 7 which has a flat comb shape and can be accommodated in the groove 3 of the carriage 1.
A roller 8 is rotatably mounted on each of the comb teeth so that the spring unit 51 can be smoothly placed from the side. Although the number of comb teeth is four in the figure, it is preferable to be about ten in practice. The movable base 6 has a plurality of legs 9 at the base side of the comb teeth. Each of the legs 9 has a caster 10 attached thereto and is supported by the cart 1 at the tip side of the comb teeth. Reciprocates between the first working position A and the second working position B in accordance with However, as described above, the carriage 1 is not only between the first working position A and the second working position B, but also the first working position A and the third working position C.
The movable table 6 does not move toward the third working position C due to the presence of the stopper 11 at the first working position A, and the carriage 1 moves from the first working position A to the third working position C. As the vehicle travels to the first working position A, it is relatively pulled out of the carriage 1 like a drawer while staying at the first working position A. In the expression of the drawer, while the carriage 1 reciprocates between the first work position A and the second work position B, the movable platform 6 is driven as a drawer while being stored in the carriage 1. Further, as shown in FIG. 3, the groove 3 of the carriage 1 and the support 7 of the movable base 6 slide by a combination of U-shaped channel members (the channel member is not shown in FIG. 4, but has a similar structure). It has become).

The moving table 6 has a lifting drive unit 12 such as a hydraulic cylinder so that the support unit 7 can be moved up and down in a horizontal state. The upper stop position of the support portion 7 is such that its upper surface is a predetermined distance (about 25 mm) from the support surface 2 of the carriage 1.
The position where the support portion 7 is stopped and the lower stop position of the support portion 7 is such that the upper surface thereof is a predetermined amount (approximately 10 m
m) It becomes lower, and selectively stops at one of the upper stop position and the lower stop position as the elevation drive unit 12 operates. The support unit 7 is moved up and down in this manner because the movable platform 6 staying at the first working position A receives the next spring unit 51 alone when the carriage 1 is moving toward the third working position C. The spring unit 51 can be transferred onto the support surface 2 of the truck 1 immediately when the truck 1 comes from the third working position C to the first working position A.

[0011] A case holding portion 1 arranged above the carriage 1
Reference numeral 5 has an unillustrated suction means, and has a function of holding or releasing the case 53 by switching ON / OFF of the suction means. Case holder 1
5 has pressing and cooling means (not shown), and the pressing and cooling means

The inversion support portion 25 lifts the spring unit 51 as the 6 is operated, and has a function of inverting the spring unit 51 up and down. The number of comb teeth is four in the figure, but in practice, about six is preferred.

Next, a method of manufacturing a mattress by operating the above manufacturing apparatus will be described. That is, first, the spring unit 51 to be assembled is put on standby at the standby position D, and one sheet 53 is placed on the spring unit 51 in a non-bonded state. At this time, the spring unit 51 and the case 53 are accurately positioned in a planar manner. Next, the spring unit 51 on which the case 53 is mounted is sent to the first working position A, and is mounted on the support portion 7 at the stop position of the moving table 6. This feeding is performed easily because the roller 8 is rotatable. Next, the support unit 7 of the movable base 6 is lowered to the descent stop position, and the support of the spring unit 51 is left to the support surface 2 of the carriage 1. Further, before and after this, the case 53 placed on the spring unit 51 is adsorbed to the case holding portion 15 and once lifted off the spring unit 51.

Next, the carriage 1 is moved from the first working position A to the second working position B together with the movable base 6 by the spring unit 51.
And the adhesive is applied to the upper surface of the spring unit 51 when the spring unit 51 passes through the adhesive applying section 18. Next, one padding 52 is placed on the spring unit 51 that has come to the second working position B by the padding mounting portion 21. Then, trolley 1

When the spring unit 51 on which the padding 52 is placed passes through the adhesive application section 18, the adhesive is applied to the upper surface of the padding 52.

Next, at the first working position A, the case 53 once removed is further placed on the padding 52 placed on the spring unit 51, and the case holding portion 15 transfers the case 53 from the spring unit 51, the padding 52 and the case 53. The laminates are firmly fixed to each other. In this step after the case 53 is mounted again, the carriage 1 travels from the first working position A to the third working position C, and the case holding unit 15 moves from the first working position A to the third working position C accordingly. It is performed in the process of doing. At this time, the moving table 6 stays at the first working position A and does not move, and receives another spring unit 51 to be assembled next from the standby position D. When the bogie 1 reaches the third working position C and stops,
The reversing unit 24 is operated to put the padding 52 and the case 5 on the upper surface.
3 is lifted, and after the cart 1 and the case holder 15 return to the first working position A,
The spring unit 51 is turned upside down. The spring unit 51 is inverted and moves to the reversing receiving position E, is returned from the reversing receiving position E to the first standby position D, and repeats the same procedure again, this time on the lower surface side (however, at this time, The padding 52 and the case 53 are bonded to each other (facing upward).

Therefore, according to the above-mentioned manufacturing apparatus, this kind of mattress in which the padding 52 and the case 53 are laminated and adhered to the upper and lower surfaces of the spring unit 51, respectively, can be manufactured efficiently. Since the production of the second set of mattresses is started without waiting for the mattress to be completed, the working time can be significantly reduced. In addition, the spring unit 5 which has been returned to the first working position A after going to the second working position B,
First, the spring unit 5 is stopped so that it stops exactly where it was located before this reciprocation.
If the case 1 and the case 53 are accurately aligned, the spring unit 51 and the case 53 can be bonded in a precise positional relationship with the padding 52 sandwiched therebetween. And a product with high combination accuracy can be manufactured.

[0019]

The present invention has the following effects. In other words, the manufacture of a mattress in which a padding and a case are laminated and bonded to the upper and lower surfaces of the spring unit, respectively, can be performed swiftly. Work time can be greatly reduced. Also, the spring unit, which went to the second working position, loaded the padding and returned to the first working position, stopped at exactly the same position as it was before this reciprocation, so that the spring If the unit and the case are accurately aligned, the spring unit and the case can be bonded in a precise positional relationship with the padding sandwiched therebetween. Therefore, a product with high combination accuracy can be manufactured while shortening the operation time.
