Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sheet joining device used for joining sheet-like objects such as photographic paper (hereinafter also simply referred to as "sheet bodies"). It is something.

[Technology background]

For example, in the formation of photographs, a printing process is required to print an image corresponding to a negative film onto photographic paper, and a developing process is to develop the photographic paper after the printing process. In the printing process, for example, a black and white photographic paper or a color photographic paper having a photosensitive layer containing a dye image forming substance such as a yellow dye substance, a magenta dye substance and a cyan dye substance is sequentially transferred to an exposure section. In the exposure section, a light image corresponding to the negative film of the photography and development method is projected onto the photographic paper for exposure processing, and then the exposed photographic paper is subjected to a developing process, for example, development.

After undergoing processes such as fixation, stabilization, washing with water and drying, it becomes a finished product.

However, recently, it has become possible to easily develop negative film, print it onto photographic paper, and develop it at end-level vendors such as camera stores, making it possible to quickly create photographs at low cost. Automatic photographic printing and developing devices ρ are being actively developed.

However, the developer used for development in the development section becomes fatigued as the development process progresses, so it is necessary to appropriately manage whether or not development is being carried out under appropriate conditions. For example, an undeveloped developer test piece (hereinafter referred to simply as "
Also called "control strip." ) may be actually developed and tested for the degree of fatigue of the developer. Specifically, this control strip is supplied to the developing section to be tested and developed, and the resulting test image is compared with a standard image obtained by developing the control strip under standardized development conditions. However, based on this comparison result, it may be determined whether or not the developer needs to be replaced.

[Problem that the invention seeks to solve]

As a means for supplying the control strip to the developing section, for example, it is conceivable to provide a conveying system exclusively for the control strip in the developing section, separate from the conveying system for photographic paper for forming photographs. However, providing a transport system exclusively for the control strip in this way not only complicates the structure of the device (but also increases the manufacturing cost).

For this reason, it is desirable to carry out a test to determine the fatigue level of the developer by transporting the control strip using a transport system for photographic paper instead of providing a dedicated transport system for the control strip. . However, in the developing section, a conveyance mechanism using rollers is usually provided, but in order to reduce manufacturing costs, the number of rollers is reduced, and for this reason, the number of conveyed objects required for conveyance is reduced. The minimum length is relatively large. Therefore, when conducting a test to determine the fatigue level of the developer by supplying a control strip to the developing section using a conveyance system for photographic paper, the length of the control strip required for conveyance must be However, the length may be longer than that required for testing the degree of developer fatigue.

However, since control strips are expensive, it is desirable to be able to conduct the test with the minimum length required for testing the degree of fatigue of the developer. A strip of photographic paper or similar material is attached to the end of the control strip to ensure the minimum length necessary for the fatigue test and for transport in the development section. It is extremely economical to perform a test to examine the degree of fatigue of the developer by bonding a conveying league made of paper or the like and supplying the combined body of the control strip and the conveying league to the developing section.

In order to make it possible for end businesses such as camera stores to economically carry out tests to determine the degree of developer fatigue, a device for joining a conveyor league to the tip of the control strip is required. Moreover, the control strip must not be exposed to light during this joining process, so it is necessary to perform the joining process in a dark bag, and it is convenient to use adhesive tape as the means for joining. Preferably, it is desirable that the bonding operation using the adhesive tape can be easily performed even in a dark bag.

[Purpose of the invention]

The present invention has been made based on the above-mentioned circumstances, and an object thereof is to provide a sheet body joining device that can easily join sheet bodies to be joined using an adhesive tape.

[Means for solving problems]

The sheet body joining apparatus of the present invention includes a base and a first base on the base.
The sheet body to be joined and the second sheet body to be joined are adjacent to I! When the adhesive tape is placed, a part of the adhesive tape is positioned slightly above the adhesive area including the boundary line between the first sheet to be joined and the second sheet to be joined. It is characterized by comprising an adhesive tape holding part that is held by adhesion.

According to this configuration, since the adhesive tape holding part that holds the adhesive tape by adhering a part thereof is provided, the adhesive tape used as the joining means can be held in advance in the adhesive tape holding part. This eliminates the possibility of accidents such as the adhesive tape accidentally adhering to parts other than those to which it should be applied, and allows the first sheet to be joined and the second sheet to be joined easily by manual operation in a dark bag. The sheet body to be joined can be joined using an adhesive tape.

〔Example〕

Hereinafter, the embodiments of the present invention will be described with reference to the drawings for an example of a sheet joining device when used to join a control strip and a conveying league used for testing a developer in a developing device for photo forming. This will be explained in detail.

Preferably, the opposing side surfaces are parallel to each other, and these positioning members 21 and 2
2 are fixed members 25 and 2, such as screws, so that the distance between them matches the width of the first sheet body to be joined.
6 is fixed to the base 1. These positioning members 21 and 22 are configured so that the distance between them can be changed according to the width of the first sheet to be joined,
In this example, the distance NL between the positioning members 21 and 22 is set to the first value without moving the center line P1 between the positioning members 21 and 22.
For example, fixing screw holes 23 and 24 are provided at appropriate positions so that the width can be changed according to the width of the first sheet body to be joined, and the positioning screw holes 23 and 24 are provided at appropriate positions so that the positioning holes can be changed according to the width of the first sheet body to be joined. By selecting the fixing positions of the members 21 and 22, it is possible to join even when the widths of the first sheets to be joined span several types.

3 is a holding member for the first sheet body to be joined, and in this example, the base 1 is placed so that one end 31 of the holding member 3 extends, for example, in the same direction as the center line P1 between the positioning members 21 and 22. It is rotatably supported on a shaft 32 provided on one edge side, and contacts the first sheet to be joined set between the positioning members 21 and 22 on the lower surface of the pressing member 3. The U-shaped portion 36 is provided with a protective layer (made of, for example, terremp, felt, etc.) so that the surface of the first sheet to be joined can be held between it and the base 1 without damaging the surface. (not shown because it is hidden and cannot be seen). 34 is a magnet for suctioning and fixing the other end 33 of the holding member 3; this magnet 34 is fixedly provided, for example, on the upper surface of the base 1;
The upper surface of this magnet 34 is higher than the upper surface of the positioning member 21. When the holding member 3 is closed and the other end 33 is suctioned and fixed to the magnet 34, the protective layer comes into contact with the upper surface of the first sheet to be joined set between the positioning members 21 and 22, and As a result, the first sheet to be joined can be attached to the base 1 without shifting its position.
is held between.

41 and 42 are positioning members for the second sheet to be joined, and these positioning members 41 and 42 are used to position the base 1 in a second region adjacent to the first region of the base 1. These positioning members 41 and 42 protrude from the upper surface at a height greater than the thickness of the second sheet body to be joined, and preferably, the center line P2 between them is the center between the positioning members 21 and 22. The side surfaces facing each other are parallel to each other so as to coincide with the line P1, and the distance l between these positioning members 41 and 42 is set, for example, to match the width of the second sheet to be joined. It is fixed to the base 1 with fixing members 45 and 46 such as screws. In this example, the end edges 43 and 44 of the positioning members 41 and 42, which are opposite to the ends of the positioning members 21 and 22, extend along the same line Q perpendicular to the center line P1, When the first sheet body to be joined is positioned between the positioning members 21 and 22, the end edge of the sheet body to be joined of the cylinder 1 is brought into contact with the end edges 43 and 44 for positioning. It also functions as a stopper in the direction of the center line P1. In this example, the positioning members 41 and 42 are not configured so that the distance l between them can be changed, but depending on the case, these positioning members 41 and 4
2 may be configured such that, for example, a fixing hole is provided at an appropriate position so that the distance l between them can be changed without moving the center line P2, and in this case, the second By selecting the fixing positions of the positioning members 41 and 42 according to the width of the sheet to be joined
Welding can be performed even when the sheet bodies to be welded have several widths.

5 is a holding member for the second sheet body to be joined, and in this example, one end 51 of the holding member 5 is connected to the shaft 32.
A U-shaped portion 56 that is rotatably supported together with the pressing member 3 and comes into contact with the second sheet to be joined set between the positioning members 41 and 42 on the lower surface of the pressing member 5. A protective layer 55 made of, for example, terrestrial foam, felt, etc. is provided on the tube 2 so that the surface of the sheet to be joined can be held between the tube 2 and the base 1 without damaging the surface. Reference numeral 54 denotes a magnet for suctioning and fixing the other end 53 of the holding member 5. This magnet 54 is fixedly provided, for example, on the upper surface of the base 1, and the upper surface of this magnet 54 is higher than the upper surface of the positioning member 41. It's getting expensive. When the pressing member 5 is closed and the other end 53 is suctioned and fixed to the magnet 54, the protective layer 55 is placed on the upper surface of the second sheet member to be joined set between the second positioning members 41 and 42. As a result, the second sheet to be welded is held between the base l and the second sheet body without shifting its position.

7 is an adhesive tape holding part, and in this example, the adhesive tape holding part 7 is, as shown in FIGS. 4 and 5,
It is fixed to the holding member 5 and is configured to be movable in conjunction with the opening/closing operation of the holding member 5. The adhesive tape holding section 7 is configured to adhere a portion of the adhesive tape so that the adhesive tape is positioned slightly apart above the adhesive area including the boundary line between the first sheet body to be joined and the second sheet body to be joined. The roller holding part 72 is connected and fixed to the pressing member 5 by screws 73, for example.

When the pressing member 5 is closed and the end portion 53 is suction-fixed to the magnet 54, the rotating roller 71 extends along the line Q perpendicular to the center line P1, and extends along the base 1.
above! ! It is disposed so as to be located close to a bonding area including a boundary line between the first sheet body to be joined and the second sheet body to be joined. This rotating roller 7
The distance between the center axis of 1 and the boundary line between the first sheet to be joined and the second sheet to be joined is set taking into consideration the width of the adhesive tape to be used. 8 on the rotating roller 71, and then press the adhesive tape 8 with your fingers and apply it to the part to be joined. It is preferable to set the distance such that the area is approximately equal. The length of the rotating roller 71 is, for example, smaller than the width of the shorter one of the first sheet body to be joined and the second sheet body to be joined.

The roller holding section 72 includes a connecting plate 74 connected to the pressing member 5, and temporary bearings 75 and 76 extending from both sides of the connecting plate 74 to rotatably hold the shaft of the rotating roller 71. This bearing has temporary 75 and 7
The upper end surfaces 77 and 78 of the adhesive tape 8 are respectively set at approximately the same level as the height of the rotating roller 71 or slightly higher than this, and when the adhesive tape 8 is held on the rotating roller 71, one end and the other end of the adhesive tape 8 are held at the same time. The bearings are configured so that they can also be attached to the upper end surfaces 77 and 78 of the plates 75 and 76, respectively, and this prevents the rotating roller 71 from rotating freely, so that the retained adhesive It is possible to prevent an accident in which the tape 8 gets wrapped around the rotating roller 71. And on both sides of the connecting plate 74, the bearings are connected to the plates 75 and 7.
stopper portions 79 and 80 rising upward from each of the adhesive tapes 8 and 6 are provided.
1, by holding one side edge of the adhesive tape 8 in contact with the stopper parts 79 and 80, the adhesive tape 8 can always be held in a predetermined position. It has become.

In this example, a projecting piece 6 extending to the lower surface of the pressing member 5 is fixedly provided on the lower surface of one end of the pressing member 3, and when closing the pressing member 3 and the pressing member 5, the pressing member 3 is pressed first. The member 3 is closed to hold the first sheet body to be joined between it and the base 1, and then the pressing member 5 is closed and the second sheet body to be joined is held between it and the base 1. Then, in this state, the two are joined, and after the joining is completed, the pressing member 5 can be removed by lifting only the pressing member 3 by hand.
is automatically lifted by the protruding piece 6, so that the joined body can be removed from the base 1 after joining by a single operation of lifting the presser member 3, which is an extremely convenient configuration in practice.

Although not shown, for example, the control strip used as the second sheet to be joined needs to be handled without being exposed to light, so a dark bag is provided to surround the above components, and during the joining process, the control strip must be handled without being exposed to light. The joining work is carried out by hand through the holes provided in the .

Using such an apparatus, a control strip (a second sheet to be bonded) and a conveying league (a first sheet to be bonded) are used to conduct a test to examine the degree of fatigue of a developer in a developing device for photographic formation. In the case of joining a first sheet to be joined, that is, a conveying league having a width corresponding to the width between the conveying guides of the developing section.

This conveying league is made of, for example, photographic paper or a material similar to paper that has mechanical strength 3 and elasticity similar to that of photographic paper and does not harm the developer. In one developing device, the distance between the transport guides is usually fixed, so the transport league is cut to the length necessary for transport with a width corresponding to the distance between the transport guides. It is convenient to form a large number of them in advance. Furthermore, if such a conveying league is prepared in advance by the manufacturer of the developing device, it may be used. In order to butt the conveyor league against the control strip and join it without any gaps, the edge of the conveyor league that joins the control strip must be approximately perpendicular to the side edge. Otherwise, a part of the adhesive surface of the adhesive tape used as a joining means may be exposed, and when conducting a test to check the fatigue level of the developer using a bonded product in such a state, Since the developer adheres to the exposed adhesive surface of the adhesive tape and is transported through the developing device together with the bonded body, it may contaminate the inside of the developing device. It becomes difficult to straightly join the sheet body and the control strip, and the adhesion width of the adhesive tape becomes small, so that the required joining strength may not be obtained.

Next, prepare an adhesive tape having a length and width suitable for joining this conveying league and the control strip,
A part of this adhesive tape is adhered to the rotating roller 71 and held by the rotating roller 71.

In this holding operation, one side edge of the adhesive tape is brought into contact with the stopper parts 79 and 80, and one end and the other end of the adhesive tape are held in the bearings 75 and 7, respectively.
It is held so that it also adheres to the upper end surfaces 77 and 78 of 6. The adhesive tape is not particularly limited, but it must be one that does not have an adverse effect on the developer, and must not lose its adhesive properties due to the developer.

The size of the adhesive tape may be large enough to provide enough bonding strength to prevent it from separating when transported in the developing section, but if the adhesive surface of the adhesive tape protrudes from the joint and is exposed, the adhesive tape may be damaged. In order to avoid developing solution adhering to the surface and contaminating the inside of the developing device, the length of the adhesive tape is usually such that the width of the control strip is smaller than the width of the transport league. Therefore, the width should be smaller than the width of the shorter control strip.

And the other ends 33 and 5 of the pressing member 3 and the pressing member 5
3 are both spaced apart from the top surface of the base 1, and in this state, the conveyor league is placed between the positioning members 21 and 22, and the conveyor league is moved, for example, while sliding on the base l. The end edges of the conveying league are brought into contact with the end edges 43 and 44 of the positioning members 41 and 42. Then, the holding member 3 is closed so that the portion on which the protective layer is provided comes into contact with the upper surface of the conveying league, and the other end 33 is fixed by suction with the magnet 34.

Next, a control strip is placed between the positioning members 41 and 42, and the control strip is moved, for example, by sliding on the base 1, so that the end edge of the control strip is already held on the base 1. Make sure that it is in contact with the end edge of the transport league without overlapping it! 5
! place At this time, if the control strip is placed so as to overlap the conveying league, a step will be formed at the joint, which may cause a conveyance failure when the combined body of both strips is conveyed into the developing section, which is not preferable.

Then, the pressing member 5 is closed so that the portion on which the protective layer 55 is provided comes into contact with the upper surface of the control strip, and the other end 53 is fixed by suction with the magnet 54.

With the transport league and control strip thus placed on the base 1 in a predetermined posture,
Press the adhesive tape held on the rotating roller 71 with your fingers and stick it to the adhesive area including the boundary line between the conveying league and the control strip located below, and then move the conveying league along the center line P1. When pulled out from the base 1, the adhesive tape is attached to the rotating roller 71 and the bearing is attached to the plate 75.
Since the adhesive tape comes off from the upper end surfaces 76 and 77 of the adhesive tape 76, the unattached portion of the adhesive tape is pressed down with fingers to adhere the entire adhesive surface of the adhesive tape.

After the joining is completed in this way, when the other end 33 of the holding member 3 is lifted, the holding member 5 is automatically lifted together with the protruding piece 6, and then the joined body of the conveying league and the control strip is removed. , the joining work is completed.

According to the sheet joining apparatus configured as described above, since the adhesive tape holding part 7 is provided which holds the adhesive tape by adhering a part thereof, the adhesive tape used as the joining means is held in advance by the adhesive tape holding part 7. Since the adhesive tape can be held in the part 7, there is no possibility of accidents such as the adhesive tape accidentally adhering to parts other than the part to which it should be applied.
The control strip and the conveyor league can be easily joined with adhesive tape by manual operation in a dark bag.

In the adhesive tape holding section 7, the bearings are arranged such that the upper end surfaces 77 and 78 of the temporary 75 and 76 are at the level of the rotating roller 71.
When holding the adhesive tape on the rotating roller 71, the bearings simultaneously hold one end and the other end of the adhesive tape on the upper end surfaces 77 and 7 of the plates 75 and 76, respectively. This prevents the rotating roller 71 from rotating freely while the adhesive tape is being held, thereby preventing the held adhesive tape from wrapping around the rotating roller 71. can be prevented from occurring.

On both sides of the connecting plate 74 in the adhesive tape holding part 7, the bearings are provided with stopper parts 79 and 80 rising upward from the plates 75 and 76, respectively, so that the adhesive tape can be rotated in the dark bag. 71, by holding one side edge of the adhesive tape in contact with the stopper parts 79 and 80, the adhesive tape can always be held in a predetermined position. As a result, in the work of joining the control strip and the conveying league, the adhesive tape can always be applied to the adhesive area in a constant state, and stable joining can be achieved.

Therefore, when conducting a test to examine the degree of fatigue of the developer using the thus obtained combined body of the control strip and the conveying league, the width of the conveying league should be Since the width of the control strip is smaller than the distance between the transport guides, it can be safely transported in the developing section, and the length of the control strip can be used to check the fatigue level of the developer. Since the length can be reduced to the minimum required for the test, control strips, which are generally expensive, can be used very economically, and in cases where photographs are formed using automatic photographic printing and developing equipment in camera shops and the like. It becomes possible to form photographs at low cost.

Although the present invention has been described above based on one embodiment, the present invention can be modified as appropriate. The structure is not particularly limited as long as it has a structure, and for example, a non-rotating wire or a plate may be used instead of the rotating roller 71. Further, the adhesive tape holding portion 7 may not be fixed to the holding member 5, but may be fixed to the holding member 3, or may be fixed to another holder.

〔Effect of the invention〕

The present invention is a sheet joining apparatus having the following configuration, and is provided with an adhesive tape holding part that holds the adhesive tape by adhering a part thereof. Since the adhesive tape can be held in the adhesive tape holder, there is no accidental sticking of the adhesive tape to a part other than the part to which it should be applied, and it can be easily operated by hand in a dark bag. The first sheet body to be joined and the second sheet body to be joined can be joined with an adhesive tape.

Therefore, when conducting a test to check the degree of fatigue of the developer in an automatic photographic printing/developing device, it is necessary to attach the control strip, which is the second sheet to be joined, to the conveying strip, which is the first sheet to be joined. The ability to easily join together the control strips allows for economical use of control strips by minimizing the length of control strips required for testing, while also allowing the length of control strips to be as long as necessary for transport in the developer section. This makes it possible to carry out a test for determining the degree of fatigue of the imaging liquid extremely economically.

In addition, in the assembly of the transport league and the control strip, only the transport league needs to have a width that matches the distance between the transport guides in the developing section.
A control strip whose width is smaller than the width between the conveyance guides can be used, and from this point of view as well, the control strip can be used more economically.

In the end, automatic photo printing and
When forming photographs using a developing device, tests to determine the degree of fatigue of the developing solution can be easily carried out, and control strips can be used economically, reducing the cost required for forming photographs. This provides great advantages.
