Benefits of technology

The present invention aims to solve the problem of a conventional processing apparatus that causes a belt-like work to temporarily stop at every processing position, which can lead to a deviation in position for processing. The invention provides a processing apparatus that can intermittently halt and process a continuous belt-like work while causing the work to travel along a predetermined path. This ensures that the belt-like work is physically halted at the processing position, and the tension applied to it is maintained stable.

Problems solved by technology

This halt, however, affects the carrying at processing positions immediately upstream and downstream of the press-working position.

first embodiment

[0071]FIGS. 4A and 4B are side views of a processing apparatus 10 according to a first embodiment. Note that, in order to keep the figures from becoming complicated, FIG. 4A shows the processing apparatus 10 without its tension-variation-suppressing mechanism 37, which is a component of the apparatus 10, and conversely, FIG. 4B shows the apparatus with its tension-variation-suppressing mechanism 37 but without the belt-like work 1.

[0072]Further, as shown in FIG. 4A, the vertical direction is referred to below also as the up and down direction, and the horizontal direction orthogonal to the vertical direction is referred to below also as the front and rear direction. Incidentally, the “front” of the front and rear direction is the downstream side of the carrying direction of the belt-like work 1, and the “rear” is the upstream side of the same. Further, the upstream side of the processing apparatus 10 is referred to also as the entering side, and the downstream side of the same is re...

second embodiment

Modified Example of Second Embodiment

[0121]FIG. 11 is a side view of a processing apparatus 10b according to a modified example of the second embodiment. The second embodiment uses an air cylinder as the oscillation drive device 36 of the seesaw member 34, but the present modified example uses a cam mechanism instead. The features other than this are almost the same as those in the second embodiment, and for example, a brake-equipped non-drive roll 31d is disposed in place of the drive roll 31b, like the above-described second embodiment.

[0122]The oscillation drive device 38 employs, as its main element, a substantially-oval disk-like plate cam 38 that is rotatable about a predetermined axis 38c, for example. The plate cam 38 is arranged in such a manner that its outer circumferential surface serving as a cam surface comes into contact with the lower surface of the seesaw member 34 at a position more to the entering side than the oscillation central shaft 34c of the seesaw member 34...

Abstract

A processing apparatus includes: a work carrying section that carries a continuous belt-like work; and a processing section within a travel path and processing while the work is being intermittently halted. The work carrying section includes an entering-side buffer mechanism within the travel path on an upstream side of the processing section; an exit-side buffer mechanism within the travel path on a downstream side of the processing section; an interlocking section that moves first and second moving elements for performing a reciprocating movement in an interlocked manner; an intermittent sending section that comes into contact with the work; an endless annular element that is wrapped around the carry rolls and the first and second moving elements; and a first drive roll that applies a rotational force to the carry rolls and a moving force to the first moving element and the second moving element.

Description

TECHNICAL FIELD[0001]The present invention relates to a processing apparatus for intermittently halting and processing a continuous belt-like work while causing the work to travel along a predetermined travel path.BACKGROUND ART[0002]As shown in FIG. 1, a conventional production line 5 for disposable diapers, for example, includes a plurality of processing positions P1, P2, . . . aligned front-to-rear along the horizontal direction. Semi-finished diapers are carried continuously in the form of a continuous belt-like work 1, and during this course, various processes are applied thereto at the respective processing positions P1, P2, . . . to thereby complete finished products.[0003]In cases where press-working is to be applied at one of the above-mentioned processing positions P1, P2, . . . , carrying of the belt-like work 1 will be intermittently halted with every die-pressing motion using press dies. This halt, however, affects the carrying at processing positions immediately upstre...
