Abstract

PURPOSE: To provide a presser designed to make wrinkles hard to develop on parts. CONSTITUTION: Between a subpressing part S and a main pressing part M, the sandwiching traveling parts 13, 14 of both upper and lower flat belts 11, 11 are moved under contact along the circular outer circumferential surface 9 of an upper revolving press roller 6. Therefore, parts sandwiched between these traveling parts 13,14 are also unloaded under pressure by the main pressing part M stably along the surface 9 between both the pressing parts M and S. The tangential partial force F1 of a pressing force F acts as the force pulling the above traveling parts 13, 14 and the parts oppositely to the direction D of conveying the parts. Therefore, the traveling parts 13, 14 and the parts sandwiched therebetween are subjected to pressure contact with each other along the surface 9 under tension by the conveying force in the direction D and the tangential partial force F1 opposite thereto, and the sandwiched parts are stretched in both the directions.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressing machine for various parts, and in particular, it heats parts that have an interlining layer on a cloth through an adhesive (a large number of adhesive particles or adhesive film sheets). The present invention relates to a continuous interlining cloth bonding machine for clothing, in which the adhesive is melted and then pressured to bond.

[0002]

2. Description of the Prior Art In a conventional continuous interlining cloth bonding machine for clothes disclosed in Japanese Patent Laid-Open No. 6-286900, parts are sandwiched between upper and lower flat belts and conveyed from the parts inlet side to the parts outlet side. The upper and lower flat belts are arranged close to each other so as to obtain a heater for heating the parts through the upper and lower flat belts between the parts carry-in side and the part carry-out side. Both upper and lower rotary press rollers are provided on the carry-out side for final pressing of the parts sandwiched between the upper and lower flat belts via the upper and lower flat belts.

In particular, as shown in FIG. 4, the rotary pressing roller 36 is provided on the part unloading port 4 side, upstream of the main pressing portion M between the upper and lower rotary press rollers 6 and 8 in the part conveying direction D. Is adjacent to the lower rotary press roller 8 and is pressed against the upper and lower endless flat belts 11 and 12 from below. The rotary pressing roller 36 allows the parts sandwiched between the upper and lower flat belts 11 and 12 to be attached to each other.
Pre-pressurize via 1 and 12.

[0004]

However, there is no support for the upper and lower flat belts 11 and 12 between the main pressing portion M between the upper and lower rotary pressing rollers 6 and 8 and the rotary pressing roller 36. Both flat belts 11 and 12 flex freely in the vertical direction, and the upper and lower flat belts 11 and 12 are in an unstable state between them. Moreover, before the pressurization, since the adhesive has not been melted yet, the cloth and the interlining are still in a state of being easily displaced from each other. Therefore, the parts sandwiched between the upper and lower flat belts 11 and 12 are likely to be wrinkled.

Also, the upper and lower flat belts 1 which are somewhat flexible
When the upper and lower flat belts 11 and 12 are sandwiched in the main pressing portion M between the upper and lower rotary press rollers 6 and 8, the thickness of the upper and lower flat belts 11 and 12 becomes slightly thinner than the normal thickness. ,
Immediately before the main pressing portion M, the upper and lower flat belts 11 and 12 slightly inflate vertically due to the thickness change. However, if such a bulge occurs on the upper and lower flat belts 11 and 12,
The bulging portion serves as a conveyance resistance, and the upper and lower flat belts 11 and 12 are easily bent between the main pressing portion M and the rotary pressing roller 36 so as to undulate in the vertical direction. Therefore, the parts sandwiched between the corrugated upper and lower flat belts 11 and 12 are likely to be wrinkled, which lowers the commercial value.

It is an object of the present invention to improve the positional relationship among the rotary pressing roller, the rotary pressing roller and the belts so as to prevent wrinkling of parts as much as possible.

The large lever 30 is rotated via 2 and the lower rotary press roller 8 on the lower drive shaft 7 is pressed against the upper rotary press roller 6 via the upper and lower flat belts 11 and 12.

On the upstream side of the lower rotary press roller 8 in the part conveying direction D, a rotary support shaft 33 is provided between the upper rotary press roller 6 and the rotary support shaft 29 along the rotary support shaft 29. Small levers 34 are erected and supported on both sides of the rotation support shaft 33 in the axial center 33a direction so as to be integrally rotatable on a vertical surface. The upper and lower drive shafts 5, 5 are provided between the tips of the levers 34.
A driven shaft 35 extending along the axis 7 is rotatably supported, and a rotary pressing roller 36 is supported on the driven shaft 35. A circular outer peripheral surface 37 centered on the shaft center 35a of the driven shaft 35 is formed on the rotary pressing roller 36. The diameter of the circular outer peripheral surface 37 is such that the upper and lower rotary press rollers 6, 8 and the circular outer peripheral surface 9,
It is smaller than the diameter of 10.

Pressing cylinders 38 are rotatably mounted in the vicinity of the large levers 30, respectively, and the tips of their piston lots 38a are connected to the small levers 34 on the axis 35a of the driven shaft 35. The expansion / contraction direction E of the piston lot 38a passes through the axis 35a of the driven shaft 35.

(C) An adhesive film sheet before melting is placed between the cloth and the interlining material, and heaters 27, 28 are applied before the pressing.
As a result, the adhesive film sheet is melted, so that the cloth and the interlining are easily bonded to each other.

In addition to the above embodiment, the following (a) to (c) may be adopted. (A) The upper and lower heaters 27 and 28 are omitted in the above embodiment. In this case, the molten adhesive is applied between the cloth and the interlining in the part P to be placed on the part supply / placing surface 14a of the nip traveling portion 14 of the lower rotary press roller 8.

(B) In the above embodiment, the rotary shaft center 5 a of the upper rotary press roller 6 and the rotary shaft center 35 of the rotary pressing roller 36.

All the pressing force F of is applied in the normal direction. In this case, the tangential force F _t described above does not work, but both pressure parts M,
Since the upper and lower sandwiching running portions 13 and 14 and the part P can be arranged along the circular outer peripheral surface 9 of the upper rotary press roller 6 between S, the conveying state thereof is stable, and the part P is less likely to be wrinkled.

(C) In the above-described embodiment, the rotary shaft center 5a of the upper rotary press roller 6 and the lower rotary press roller 8
The lower rotary press roller 8 is pressed against the upper rotary press roller 6 in the direction normal to the rotary shaft center 7a. The pressing direction of the lower rotary press roller 8 may pass through an eccentric position on the downstream side of the rotary shaft center 5a of the upper rotary press roller 6 in the parts conveying direction D. In this case, the tangential force of the pressing force in the main pressurizing unit M acts in the part conveying direction D in addition to the conveying force, and as in the case of the rotary pressing roller 36 described above, between the pressurizing units M and S. The part P is pulled along the circular outer peripheral surface 9 of the upper rotary press roller 6.
Therefore, the part P is stretched along the circular outer peripheral surface 9 by the carrying force and the pulling force of the main pressurizing part M and the pulling force of the sub pressurizing part S, and the part P is less likely to be wrinkled.
