Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a foam bonding system suitable for use in a collating line, a packaging line, and the like.

(Prior Art) Conventionally, in a collating line or the like, as shown in FIG. 6 and FIG. 7, a plurality of continuous forms 1 having marginal punches continuous in the longitudinal direction are superposed along a feed line. A pair of upper and lower pressure rollers 2 provided on the feed line
A foam joining system for joining these continuous foam groups to each other is used.

At this time, in the foam joining system, the pin tractor 3 is disposed on the feed line, and the pin tractor 3 is rotated by being locked by the marginal punch of each continuous form 1 in the overlapping state. The continuous forms 1 can be fed at the same timing.

For example, in a collating line, the individual forms constituting each continuous form 1 fed at the same timing by the above-described pin tractor 3 are joined by the above-described pressure roller 2 while maintaining their superimposed state. Create a unit report.

(Problems to be solved by the invention) However, in the conventional foam bonding system, when a continuous foam group is fed by the pin tractor 3,
Contact forces acting in various directions are exerted between the continuous foams 1 overlapping each other, and as a result, the marginal punch of each continuous foam 1 rises randomly with respect to the pin of the pin tractor 3, and each continuous foam 1 In the width direction as shown in FIG.

And the chaotic slack of each continuous form 1 is
A side slip occurs between each of the continuous forms 1, and as a result,
The continuous foam groups are joined in a state where there is an inconsistency.

An object of the present invention is to join and integrate a plurality of individual continuous forms sent in a superposed state while preventing lateral displacement.

[Constitution of the Invention] (Means for Solving the Problems) The present invention relates to a state in which a plurality of individual continuous forms provided with a marginal punch continuous in the longitudinal direction are overlapped, and the marginal punch of each continuous form is pinned. In a foam joining system that feeds in a state of being engaged with a pin provided in a feeder and joins and joins these individual continuous forms together by a joining device provided on the feed line, a joining device in the feed line is provided. For the joint area,
It has a foam sandwiching means which is arranged on the side in a direction substantially perpendicular to the foam feeding direction and sandwiches a continuous foam group in a superposed feeding state from above and below.

(Operation) In the present invention, when a continuous form group is fed by the pin feeder, contact forces in various directions act between the continuous forms overlapping each other, and the marginal punch of each continuous form is applied. However, even if the slugs rise randomly with respect to the pins of the pin feeder and cause the slack to occur in the width direction of each continuous foam, those slacks are surely suppressed by the presence of the foam pinching means.

In this way, the continuous foams are joined in an overlapping manner, which is parallel to one another when joined by the joining device, without chaotic sagging and therefore without lateral displacement. That is,
According to the present invention, a plurality of individual continuous forms sent in a superposed state can be joined and integrated while preventing lateral displacement.

The figure is a front view showing a modification of the present invention, FIG. 4 is a schematic view showing an example of a collation line to which the present invention is applied, and FIG. 5 is a schematic view showing a continuous form.

As shown in FIG. 4, the collating line 10 includes a form feeding device 11 and a collating device 12.

The form feeding device 11 arranges the first to fourth form supply units 13A to 13D in series, and continuously draws out the first to fourth plural continuous forms 14A to 14D.

The foam feeding device 11 specifically includes a continuous form 14A to 14D including a marginal punch a continuous in the longitudinal direction and a perforation b at intervals in the longitudinal direction.
(See FIG. 5) can be extracted by rotation of the upstream pin tractor 15 and the downstream pin tractor 16 which are locked by the marginal punches a and rotate. Pin tractor 1
Details of 5 and 16 will be described later.

Then, the form feeding device 11 is provided with each continuous form 14A.
1414D are sequentially fed in a superimposed state on a feed line.

The collating apparatus 12 can perform collating work in which individual forms constituting the continuous forms 14A to 14D extracted from the form supply units 13A to 13D are overlapped with each other to form a unit form. More specifically, the collating apparatus 12 presses the individual forms superimposed on each other by a pair of upper and lower pressing rollers 17A and 17B. Reference numeral 18 denotes a servo motor that drives the pressure rollers 17A and 17B, and reference numeral 19 denotes a rotary encoder that is linked to the output shaft of the servo motor 18. Each of the continuous forms 14A to 14D is provided with a pressure-sensitive adhesive to be pressed by the pressure rollers 17A and 17B.

However, the collating device 12 has the upstream pin tractor 15 and the downstream pin tractor 16 described above on the upstream and downstream sides of the pressure rollers 17A and 17B in the feed line, respectively. Each of the pin tractors 15 and 16 is a marginal punch a for each of the continuous forms 14A to 14D in an overlapping state.
Equipped with pins 15A, 16A that engage in their continuous form
Send 14A-14D.

Each of the pin tractors 15, 16 is an oval belt 15B, 1
Pins 15A and 16A are provided at a plurality of positions in the circumferential direction of 6B, so that a plurality of pins 15A and 16A can be simultaneously engaged with a plurality of adjacent marginal punches 1 in each of the continuous forms 14A to 14D.

Further, the collating device 12 is provided with a pressing roller in the feeding line.
The foam sandwiching means is arranged on the side in the direction substantially orthogonal to the foam feeding direction (the width direction of each of the continuous foams 14A to 14D) with respect to the crimping regions of 17A and 17B. The foam pinching means includes an upper pinching roller 41A that rotates coaxially with the upper pressure roller 17A, and a lower pinching roller 41B that is an extension of the lower pressure roller 17B. And the upper and lower pinching rollers 4
1A and 41B are provided so as to face each other up and down, and squeeze each of the continuous forms 14A to 14D in a superposed state from above and below.

The lower pressure roller 17B and the lower sandwiching roller 41B may be separate bodies as shown in FIG.

Further, the upper pressure roller 17A and the upper clamping roller 41A do not need to share the same coaxial with each other, and the lower pressure roller 17B and the lower clamping roller 41B do not need to share the same coaxial with each other.

 Next, the operation of the above embodiment will be described.

In the above embodiment, when the continuous form groups 14A to 14D are fed by the pin tractors 15, 16, contact forces acting in various directions between the continuous forms 14A to 14D overlapping each other act. Even if the marginal punch a of each of the continuous forms 14A to 14D rises randomly with respect to the pins 15A and 16A of the pin tractors 15 and 16 to cause random slack in the width direction of each of the continuous forms 14A to 14D, their slacks are generated. Is reliably suppressed by the presence of the upper and lower sandwiching rollers 41A and 41B as foam sandwiching means.

As a result, each continuous form 14A to 14D
When crimping by 17A and 17B, the crimping is performed in an overlapping state that is parallel to each other and free from disorderly slackness, and is therefore free from lateral displacement. That is, according to the above-described embodiment, when the first to fourth continuous forms 14A to 14D are fed in a state of being overlapped and pressed, the lateral displacement of the pressure bonding between the forms can be prevented.

In the embodiment of the present invention, the foam pinching means may be constituted by a vertically integrated fixed shoe or the like instead of a rotating body such as pinching rollers 41A and 41B.

Further, the present invention can be applied to a packaging system and the like. [Effects of the Invention] As described above, according to the present invention, a plurality of individual continuous forms sent in an overlapped state are joined while preventing lateral displacement. Can be integrated.
