DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminating apparatus used for producing a postcard with a photograph by pasting a photograph on a postcard or laminating another sheet on another card-like sheet. More particularly, the present invention relates to a card-piece double laminating apparatus capable of performing a process from supply to lamination and discharge of a card piece reliably and in a short time.

[0002]

2. Description of the Related Art For example, in the field of postcards, it has been widely known that a photograph is placed on the back side for a greeting of a recent situation, guidance for a ceremony, or the like. As one of them, New Year's cards in which photographic paper is cut into a postcard shape and a photo is baked on the back side are generally widely used.

As an apparatus for manufacturing a postcard with a photograph, for example, the applicant of the present invention has proposed and filed an application.
Is described in Japanese Patent Application Publication No. In this method, a roll paper is supplied to a line as a base material for a postcard, and after applying the glue to the roll paper or applying a wet treatment to the dried paste previously applied to the roll paper, a postcard is sent out at a station for feeding out card-shaped photographs one by one. Is affixed to roll paper. Japanese Patent Publication No. 7-96352 discloses a device in which a roll of a photograph is supplied to a line, and a postcard is attached to the line.

[0004] On the other hand, postcards with photographs, in which photographs are attached to the back of plain paper having the same thickness as postcards, are economical from the point of view of various types of small-volume production, and can be easily handled even in a DPE shop, for example. It is possible, so future development is expected. Therefore, the applicant of the present application has already proposed a manufacturing apparatus in which one photo and one postcard are processed and bonded on a line without using roll paper,
The application was filed as Japanese Patent Application No. 8-136556.

In this manufacturing apparatus, a photo supply station, a glue application station for a photo, a postcard supply station, and a discharge station for discharging the pasted product are arranged in order and reciprocated in a direction to cut through each of these stations. The general configuration is to provide a suction pad that performs the operation. Then, the suction pad holds the front side of one photo by suction at the photo supply station, and then moves to the glue application station side to apply the glue on the back side of the photo,
Thereafter, the postcard is moved to a postcard supply station, where it is attached to the postcard, and the suction is released at the discharge station to collect the postcard with a photograph as a product. After the product is collected, the suction pad returns from the discharge station to the photo supply station, and thereafter repeats the same operation.

If one photo and one postcard are processed as described above, it is not necessary to provide a structure for feeding a roll of either the photo or the postcard to the line, and the number of productions Even if the number is small, small-scale production according to the number of photos prepared in advance is possible.

[0007]

However, in the process of obtaining a single postcard with a photograph, the suction pad is temporarily stopped at each of the positions where the photograph is adsorbed, attached to the postcard, and discharged. Is an intermittent operation. Therefore, there is a limitation in shortening the time from the supply of the photo to the attachment and the dispensing of the postcard, and the positioning accuracy of the suction pad with respect to each station must be strictly controlled, so that the control tends to be complicated. .

After the discharge from the discharge station, a stroke is required for returning the suction pad to the supply station of the original photograph. For this reason, not only the intermittent operation of the suction pad but also the time to return to the origin is added, so the time to complete one process becomes longer,
There is a limit to productivity improvement.

As described above, it is possible to handle single photos and postcards, but it is possible to shorten the processing time as compared with the case where a conventional roll-shaped photo or postcard substrate is fed into a line, which can be continuously processed. No optimization has been made in terms of optimization.

On the other hand, when the operation of pasting a photograph and a postcard as a pair is to be processed in a continuous line, for example, a belt or a roller row is provided as a pass line, and the photograph and the postcard are supplied to this pass line. It is conceivable to adopt a configuration in which

In such a line configuration, a system from reliable glue application, high-precision positioning between a photograph and a postcard, and shaping of a product after pasting should be considered. However, for equipment that satisfies these conditions while shortening the processing process,
It has not been developed yet.

[0012] The above problems are not only in the field of manufacturing postcards with photographs, but also in the case of various kinds of cards.
The same is true in the field of the manufacture of laminated products and the lamination process for forming a laminate such as a resin sheet.

An object of the present invention is to provide a manufacturing apparatus capable of obtaining high-efficiency and high-quality products in units of two card pieces, such as postcards with photographs.

A separate system of rotation transmitting means may be connected to the main drive motor for each of the roller rows on the line side and the first feeding unit side. In this case, the rotation transmitting means may be a timing belt connected to the shaft of each roller row.

The details are shown in FIG. In addition, about the same member as the postcard delivery unit L, what added 10 to the number of each code | symbol,
For example, in the case of a rotary actuator, the instruction is given as “15”.

In the figure, the rotary actuator 15
The timing belt 15a wound around the output shaft of FIG.
To 17d are synchronously driven to rotate. In other words, the photo delivery unit P receives the postcard 5 from the postcard delivery unit L.
There is no connection between the supply of 1 and the drive up to the conveyance to the glue application unit X, and it operates independently.

At the front end of the frame 14, a photo detection sensor 14e for detecting the front end of the photo 51 when the photo 51 is fed out is provided, and the rotary actuator 15 is controlled in cooperation with the postcard detection sensor 4d. That is, the rotary actuator 15 is driven when the controller receives a detection signal of the end of the postcard 51 by the postcard detection sensor 4d, and the one photo 52 is transferred to the nip rollers 17a to 17d.
The photograph 52 is moved to the position held by 7d, and the fed out photograph 52 waits at that position.

FIG. 5 is a detailed view showing the glue applying unit X and its vicinity.

Immediately upstream of the glue application unit X, a nip roller 10a driven by a timing belt 2a
And a pair of upper nip rollers 10

Are different from each other in height relative to the horizontal path surface into which the images are fed, and are arranged in a relationship following the obliquely downward path of the photograph from the photograph feeding unit P.

On the downstream side of the nip roller 10a, the holding roller 1 is similarly driven to rotate by the timing belt 2a and narrows the gap between the photograph 52 and the postcard 51 by gluing.
0f is provided. A nozzle 11 for applying glue and a photograph 52 are provided between the holding roller 10f and the guide roller 10e.
A back guide 12 that elastically receives the surface of the back guide 12 is arranged.

The nozzle 11 has a hollow shape as an axis perpendicular to the pass line of the postcard 51 and longer than the width of the photograph 52. One end in the axial direction is connected to an external glue press-fit pump (not shown). In addition to the communication, a discharge hole 11a having a small inner diameter is formed on the peripheral surface. This discharge hole 11
a may be arranged in large numbers at a fixed interval, or may be incised in an elongated slit shape. As shown in the figure, the cross section of the nozzle 11 has a circular paste-applied peripheral surface at the portion where the discharge hole 11a is opened, but the surface substantially perpendicular to the opening axis of the discharge hole 11a is cut away. The clearance 11b is made rotatable between the illustrated position and the position illustrated in FIG. 6 by a rotation operation.

That is, the nozzle 11 is connected to a rotary actuator 11c for rotating the nozzle 11 via a timing belt 11d, and is integrally provided with a block 11e for regulating the rotation angle. This block 11e is provided on the side of the housing 1 and abuts against a stopper bolt 11f whose position can be adjusted in the left-right direction in the figure, and the posture is restricted as shown in FIG.

The back guide 12 is a guide roller 10e.
The closed loop belt 12c is wound around a plurality of rollers including rollers 12a and 12b each having a circumferential surface opposed to the holding roller 10f. Belt 12

When the nozzle 11 rotates and assumes the position shown in FIG. 5, the circumferential surface of the discharge hole 11 a becomes the belt 12 c.
To bend and deform.

Further, as shown in FIG.
Immediately downstream of c and 9d, postcard approach detection sensors 13a and 13b are provided which detect the arrival of the leading end of the fed out postcard 51 and input the signal to the controller. These postcard approach detection sensors 13a and 13b are also arranged on the pass line as the light emitting side and the light receiving side, and upon receiving the detection signals, the rotary actuator 15 of the photograph feeding unit P is activated and the nip rollers 17c and 17d are disposed. One waiting photograph 52 is sent out in the glue application unit X direction.

7A and 7B show details of the trimming unit Y. FIG. 7A is a schematic view of a main part, and FIG. 7B is an exploded front view showing a trimming roller and a receiving roller.

The trimming unit Y has a trimming roller 21 and a pressing roller 23 disposed above a pass line and a receiving roller 22 provided below. The trimming roller 21 has one shaft 21a and elements 21b provided at both ends thereof, and a shear blade 21c is formed on these elements 21b. The receiving roller 22 has its length in the axial direction adjusted by the trimming roller 21.
Is slightly shorter than the distance between the shearing blades 21c, and is assembled such that the inner surface of the shearing blade 21c abuts on the end. Then, the trimming roller 21 and the receiving roller 22 are rotationally driven synchronously by a drive motor (not shown), and their peripheral speeds are made substantially equal to the traveling speed of the postcard 51 and the stacked body of the photograph 52 attached thereto. Control. The pressing roller 23 is rotatably connected to the lower end of the bracket 23a.
It is urged toward the pass line side by a tension coil spring 23b interposed between the upper end side of 3a and the housing 1 side.

FIG. 8 shows the details of the cutting unit Z and the vicinity thereof. The clutch roller 2 which is rotated by a timing belt 2e is provided in front of the cutting unit Z.
4 are provided. The clutch roller 24 is driven to rotate by the timing belt 2e. When the stack of postcards 51 and photographs 52 that contact and pass through the peripheral surface of the clutch belt 24 is accelerated toward the cutting unit Z and pulled out, the clutch roller 24 is incorporated. The idle rotation is enabled by a clutch mechanism. That is, when the laminate is pulled toward the cutting unit Z at a speed higher than the traveling drive speed of the timing belt 2e, the timing belt 2e is pulled by the frictional force with the peripheral surface.
The rotation of the clutch roller 24 is increased based on this friction.

The cutting unit Z includes conveying rollers 25a and 25b connected to a timing belt 3b running by a cutting motor 3, a pair of cutter units 26 and 27 interposed therebetween, and a stacked body detecting sensor 28a.
28b. Transport rollers 25a, 25
Since b is not connected to the upstream transport system and is driven by the cutting motor 3, the transport speed and the stop operation can be freely performed. Also, cutter unit 2
6 and 27 are stationary blades 26a,
27a is provided, and on the lower side of the pass line, there are provided shearing blades 26b and 27b which are moved up and down by a driving device (not shown).

In the above configuration, the main drive motor 2 and the cutting motor 3 are started to activate the timing belts 2a to 2a.
e and 3b are set to the running mode, and the rotary actuator 5 of the postcard delivery unit L is first activated.
The activation time of the rotary actuator 5 is determined by the time after the one postcard 51 at the lower end of the loaded layer is sent out by the rotation of the feeding roller 4c, and then the nip rollers 7a to 7c.
, The trailing end of the postcard 51 is detected by the postcard detection sensor 4d, and the signal is input to the controller. As a result, the one postcard 51 that has been extended is:
It enters the nip rollers 9a, 9b on the downstream side and is sent downstream.

On the other hand, the postcard 51 by the postcard detection sensor 4d
The rotary actuator 15 of the photograph feeding unit P is activated based on the detection signal of the missing part of the photograph, and one photograph 52
Is sent out in the glue application unit X direction. At this time, when the photo detection sensor 14e detects the tip of the photo 52, the rotary actuator 15 is stopped by this detection signal, and the photo 52 is stopped with the tip facing the photo detection sensor 14e and stopped.

The postcard 51 sent from the postcard delivery unit L moves toward the glue applying unit X while continuing to progress, and the progress is detected by the postcard approach sensors 13a and 13b. With the detection signals from the postcard proximity sensors 13a and 13b, the leading end of the postcard proximity sensors 13a and 13b is photographed by the photo detection sensor 14e.
The photograph 52 in which the front end is located at the portion is in a standby state, and the nip roller 1 is activated by the restart of the rotary actuator 15.
7a to 17d, and the glue coating device X
Is fed out to the nozzle 11 side by the side timing belt 10c. And the postcard 51 is also a nip roller 9c, 9
The feed is given by d and the nip rollers 10a and 10b, and advances in the direction of the roller 12b and the holding roller 10f.

On the other hand, the nozzle 11 for glue application
During the period in which the nozzle hole 1 does not pass, as shown in FIG.
1a is the belt 1 of the back guide 12 facing the upstream side.
2c is held in a position facing the clearance portion 11b. That is, the clearance 11b is connected to the belt 12c.
, And a gap is formed between the belt 12c and the front end of the photograph 52 in the gap. Then, when the photograph 52 enters, the timing is adjusted to match the timing of the rotary actuator 11.
The nozzle 11 is rotated 90 ° clockwise in FIG. 6 by controlling so that c operates. As a result, the nozzle 11 assumes a posture in which the ejection holes 11a face the belt 12c as shown in FIG. 5, and the belt 12c is pushed upward and is bent and deformed.

When the photograph 52 is fed from the timing belt 10c and is nipped between the nozzle 11 and the belt 12c, the paste discharged from the discharge holes 11a is applied to the back surface of the photograph 52. At this time, since the nozzle 11 pushes the belt 12c and deforms the belt 12c to pass through the photograph 52, the photograph 52 applies a reaction force due to the bending deformation of the belt 12c to the peripheral surface side of the nozzle 11. Therefore, nozzle 1
The photograph 52 can be sent while being in close contact with 1, and there is no occurrence of uncoated glue or the like. Immediately before the rear end of the photograph 52 comes off, the rotary actuator 11
By restarting the nozzle 11 and rotating the nozzle 11 by 90 ° counterclockwise in FIG. 5, the nozzle 11 can be returned to the initial state of FIG.
, So that the glue does not adhere to the belt 12c.

The postcard 51 having passed through the postcard approach sensors 13a and 13b and the photograph 52 coated with glue are supplied in synchronization with the holding roller 10f and the belt 12c wound around the roller 12b shown in FIG. Then, the photograph 52 is attached to the postcard 51 by the holding force between the holding rollers 10f and the rollers 12b.

In the above steps, the rotary actuator 5 of the postcard delivery unit L is always in the operation mode, and the postcards 51 are continuously fed one by one. At this time, as described above, the traveling speed of the timing belt 2c is changed to the timing belts 2b, 2a, 2
slower than e. For this reason, the postcard 51 which is fed from the postcard feeding unit L and reaches the nip rollers 9a and 9b.
, And a subsequent postcard 51 to be paid out from the nip rollers 7c and 7d. That is, when the preceding postcard 51 becomes unrelated to the postcard feeding unit L, the feeding speed is faster than the feeding speed, and the interval between the preceding postcard 51 and the subsequent postcard 51 can be increased.

Therefore, it is not necessary to operate the postcard delivery unit L intermittently, and it is necessary to use the common main drive motor 2 to carry out the delivery by the postcard delivery unit L and the position where the postcard 52 is attached to the photograph 52 on the downstream line. The feeding to the trimming unit Y can be performed in synchronization. Even if the postcard 51 is continuously sent out from the postcard delivery unit L, a margin in the feed direction can be provided between the postcard 51 and the preceding postcard 51, so that the two postcards 51 are double-fed. Nothing.

The driving of the photo feed unit P is controlled by the start and stop of the rotary actuator 15, and the postcard 51 is fed from the feed to the position where the photo 52 is pasted.
It has nothing to do with the feed. Then, after the postcard 51 is detected by the postcard approach sensors 13a and 13b, the postcard 51 is dispensed to the glue applying unit X and the glue is applied by the nozzle 11, so that the glue is applied at a timing immediately before pasting to the postcard 51. They can be operated together. For this reason,
From the time the glue is applied by the nozzle 11, the holding roller 1
The time up to the point of attachment is reduced by the 0f portion. Therefore, the photo 52 can be quickly attached to the postcard 51 at a time when the applied glue does not partially dry, and the postcard 51 and the photo 52 can be securely attached.

The postcard 51 and the photograph 52 joined to one sheet by the glue are sent to the trimming unit Y and pass between the receiving roller 22 and the trimming roller 21 shown in FIG. At this time, the receiving roller 22 and the trimming roller 21 are rotated by the contact between the supplied postcard 51 and the photograph 52, and the element 21b of the trimming roller 21 is rotated.
Shearing blade 21c trims the widthwise margins of postcard 51 and photograph 52 by shearing. In the trimming process, the pressing roller 23 presses the stacked body of the postcard 51 and the photograph 52, so that the jumping up of the stacked body can be eliminated until the stacked body comes off, and the margin width of trimming fluctuates or wrinkles are formed on the stacked body. It does not occur.

The cutting unit Z, which cuts the trimmed laminate into a final product, is independently driven by the cutting motor 3 without being driven by the upstream side, and is driven by the transport rollers 25a, 25b by the timing belt 3b. The feed speed is higher than the transport speed to the clutch roller 24 on the downstream side. That is, when the laminate enters the cutting unit Z and is nipped by the transport roller 25a, the transport roller 25a operates to pull out the laminate with respect to the feed of the clutch roller 24 side. At this time, as described above, the clutch roller 24 becomes idle due to the driving force of the timing belt 2e, and does not exert any resistance to the movement of the stacked body that moves sequentially to the transport rollers 25a and 25b. . As described above, since the feed speed of the laminate to the cutting unit Z side is higher than that of the upstream side, the interval between the conveyed subsequent laminate can be increased.

Here, it is assumed that the length of the cutting unit Z in the line direction is slightly longer than the length of the laminated body in the longitudinal direction. Then, after the laminate drawn by the transport rollers 25a, 25b is detected by the laminate detection sensors 28a, 28b, the position is controlled so as to be adapted to the cutting length, and the driving of the transport rollers 25a, 25b is temporarily performed. Stop. After this stop, the cutter units 26, 2
The cutting blades 26b and 27b of No. 7 are raised to cut both ends of the laminate.

After this cutting, the cutting motor 3 is restarted and the cut laminate is discharged to the tray 1a. Then, in the cutting unit X, the laminate is temporarily stopped for cutting. However, since a space between the laminate and the laminate from the upstream side can be provided with a margin, a stacking of the laminate is performed. There is no feeding. Therefore, even if a constant feed is given as the operation mode from the postcard receiving unit L to the transfer of the stack from the postcard receiving unit to the cutting unit X, it is not necessary to control to change the setting of this operation mode. Also, the laminate of the postcard 51 and the photograph 52 can be continuously processed.

In the above description, the apparatus for pasting postcards and photographs and collecting the laminated product is described. However, the present invention is also applicable to the field of laminating two card-shaped products to produce a product. It is a matter of course that this device can be applied.
