Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a conveying device for a group of photosensitive printing plates.

[Conventional technology]

Generally, a photosensitive printing plate is one in which a photosensitive resin is formed on a support such as an aluminum plate. This photosensitive printing plate is usually quite large, about 1 m x 1 m, and weighs 500 to 1000 g per sheet, which is quite heavy.

Conventionally, when storing or transporting photosensitive printing plates, an appropriate number of plates were stacked horizontally with interleaf paper interposed therebetween.

However, using a mount to prevent scratches,
Workability is extremely poor when stacking and taking out.

Therefore, in recent years, as shown in Figure 4, direct photosensitive printing plates 1. l, . . . overlap each other horizontally, and arrange rigid end plates 2, 2 on both sides of the mating, bolts 3,
3. ...The pallets are fastened more tightly to prevent the photosensitive printing plate from shifting due to vibrations and damaging the photosensitive surface.

In this case, one end plate 2 is used as a pallet stand, and at least one side between both surfaces of the photosensitive printing plates 1, 1... group and the end plates 2, 2 is covered with cardboard to prevent damage. has been established. Furthermore, the number of stacked sheets is usually 700 to 15.
For example, 1,000 sheets weighs 500 to 1,000 kg, so a forklift is used for transportation.

[Problem to be solved by the invention]

However, when a forklift is used to transport a group of photosensitive printing plates, it cannot pass through narrow passages in a factory, and a forklift is not maneuverable enough to transport a group of photosensitive printing plates over a short distance. Therefore, in such a case, it is necessary to transport each sheet or several sheets at a time, resulting in poor workability.

On the other hand, it is conceivable to provide the pallet with casters and transport it by hand, but when the number of photosensitive printing plates becomes large, it is practically difficult to push by hand due to the weight.

SUMMARY OF THE INVENTION Accordingly, the main object of the present invention is to provide a conveyance device that is capable of conveying a large group of photosensitive printing plates and is suitable for conveying through narrow passages or over short distances.

[Means to solve the problem]

The above problem is solved by a device that transports a large number of photosensitive printing plates having a photosensitive resin on a support by placing them in close contact with each other on a transport device stand, and the transport device stand is equipped with wheels. This solution can be solved by having the wheels configured to be driven and rotated.

[Effect]

In the present invention, wheels are provided on the transport device platform so that the transport device platform can be moved along the floor surface, and the transportation device platform can be moved by electric or mechanical drive such as a motor, or by electric or mechanical drive such as a motor, without being pushed by hand. Since the wheels are driven by manual rotation of the handle, it is possible to transport a large group of photosensitive printing plates.

Moreover, since the transport device table on which the photosensitive printing plates are placed is itself moved, it can be transported through narrow passages within the factory and is also suitable for transport over short distances.

[Specific structure of the invention]

The present invention will be explained in more detail below with reference to specific examples shown in the drawings.

In the drawings, reference numeral 1 indicates a photosensitive printing plate, and these photosensitive printing plates 1, 1... group are preferably such that the support of each adjacent printing plate 1 and the photosensitive resin surface are in direct contact without interleaving paper. and is installed as an integrated unit on a portable transport device platform, which will be described in detail below.

The bottom stand 10 constituting the transport device stand is formed into a rectangular plane by appropriately combining angles. A support reinforcing member 12 is erected on this bottom stand 1O. This reinforcing material 12
is made of square steel, for example, and is fixed to the base 10 by welding or the like. Further, when installing or taking out each printing plate from a plate-making machine, the holding plate 14 which is inclined for the stability of the group of printing plates 1.1 and the inclined base plate 16 which is orthogonal thereto are made of square steel, for example. It is formed from aggregates 14A, 16A with a framework made up of the above, and surface plates 14B, 16B made of a thin stainless steel plate fixed in advance to the surface on which the photosensitive printing plate 1 will come into contact, and both are integrally formed by welding or the like. has been made into 18 is a spacer made of a steel plate.

Further, the photosensitive printing plate groups 1, 1, . . . are sandwiched between the holding plate 14 and the other lid 20 on the base plate 16. This lid body 20 includes a reinforcing body 2OA made of, for example, a latticework of square steel pipes, and a thin surface plate 20B made of a metal plate, a plastic plate, or a composite laminate thereof, and having a thickness of, for example, 10 squares or less, preferably 5 squares or less. Consisting of

The photosensitive printing plate groups 1, 1... are, for example, long bolts 2.
2, and is clamped between the retaining plate 20 and the lid 14. For this fastening, bolt insertion holes 24 are formed in the holding plate 20. 26 is a washer. On the other hand, a bolt insertion hole 28 is also formed in the lid body 14, preferably at the position of the reinforcement body 20A, and the bolt 2 is inserted into these bolt insertion holes 24 and 28.
2 is inserted and fastened with a nut (not shown).

On the other hand, pairs of wheels 30 are provided at the lower part of the base 10 at four locations, for example, for transportation. Each pair of wheels 30 is connected by an axle 31.

These wheels are configured so that, for example, one wheel 30 at the rear in the direction of travel is driven by manual rotation of a handle 32 via a drive system that slows down the next wheel.

That is, a rotary drive handle 32 and a driving bevel gear 34 are pivotally supported by a bearing box 33 fixed to the reinforcing member 12, and a driven bevel gear 35 meshes with the driving bevel gear 34. The driven bevel gear 35 is integrated with a first sprocket 36, and the first sprocket 36 and the second sprocket 37 are connected by a first chain 38. Further, the second sprocket 27 is integrated with a third sprocket 39, and this third sprocket 39 is integrated with a fourth sprocket 40, which is integrated with the axle 31, and a second sprocket.
They are connected by a chain 41.

Now, when the rotary drive handle 32 is rotated in the direction shown, the axle 31 is rotated through each bevel gear and sprocket.
It will be readily apparent that the rear wheels 3o, 30 are rotated as a result of which the rear wheels 3o, 30 are rolled, thereby causing the carrier platform to move with the group of photosensitive printing plates placed thereon.

In the above example, when each group of photosensitive printing plates is propped up against the holding plate 14, the lid body 2o is finally placed on the plate, and the lid body 2o is clamped and fixed with the bolts 22, the transportation personnel operates the rotary drive handle 32. After rotating and transporting the entire transportation device together with a group of photosensitive printing plates to near the plate making machine (not shown), during plate making work, loosen the bolts 22, 22... and take out each plate one by one and transfer it to the plate making machine. It can be applied to.

If the direction of travel is to be changed during transportation, this can be done using a direction handle (not shown) attached like in a car.

In the above example, the wheels 30 are driven manually by the transportation personnel, but the shaft connecting the rotary drive handle 32 and the driving bevel gear 34 can also be driven by rotation by an electric motor or a fuel-powered engine (not shown). .

On the other hand, once the drive system of the wheels 30 is made into a cassette and the transportation of the transport device is completed, the drive system can be attached to another transport device and used for transportation, and such sharing reduces costs. It is possible to reduce the Further, as a modification of the above example, the rotary drive handle 32 may be simply attached to the shaft supporting the third sprocket 39.

Furthermore, the rotary drive handle may be rotated and moved by stepping on it.

Preferably in the present invention, the photosensitive printing plate is oriented substantially vertically. Also, when installed vertically, it can be installed on a stand without the interleaving paper. In other words, even if the photosensitive printing plates are cut out, as long as they are placed vertically on the table, their lower end surfaces will be in contact with the table due to their own weight, so the left and right and top There is almost no displacement of the printing plate in the direction, and damage is prevented. As a result, even if the holding plate and the lid are tightened loosely to a certain extent, the printing plates will not move easily, so tightening them loosely will prevent dirt from getting in between the printing plates. This also increases the scratch prevention effect. In this way, the ability to install an interleaf paper cutter eliminates the work of inserting an interleaf paper and removing the mount when removing a printing plate, improving work efficiency.

Furthermore, when a group of printing plates is placed substantially vertically on a table, the outer shape of one printing plate is large, about 1 m x 1 m, but the thickness is thin, measuring about 2 or 3, so even if 1000 sheets are Even when stacked, the total thickness is 200 to 300 holes, and the installation space is small.

Moreover, when a group of printing plates is transported vertically to the plate-making machine, the plate-making tools can be taken out one by one and placed on the plate-making machine, greatly improving work efficiency from transport to plate-making machine. do.

In the present invention, when 100 or more printing plates, more preferably 300 or more printing plates are provided on the table of the conveying device,
Especially the advantages are great.

Generally, photosensitive printing plates are produced by coating a photosensitive composition on a support such as an aluminum plate, irradiating it with active light such as ultraviolet rays through a negative image, polymerizing or crosslinking the irradiated areas, and applying a developer. Insolubilize and elute the non-irradiated areas into a developer, making each area an image area that repels water and accepts oil-based ink, and a non-image area that accepts water and repels oil-based ink. It is obtained by

In this case, the photosensitive composition is particularly negative-type P
For S plates, diazo resins such as condensates of P-diazodiphenylamine and formaldehyde are widely used.

However, this diazo resin is not used alone, but is usually used in combination with at least a binder resin.

Further, as the photosensitive resin, quinodiazide resin is typically used in the positive type 28 plate.

As the binder resin, polymers having phenolic OH groups and carboxyl groups, such as novolac resins, polyvarahydroxystyrene, and styrene/maleic anhydride copolymers, are mainly used.

In addition, photopolymerizable, photocrosslinkable photosensitive compositions, etc. can also be used.

In any case, a printing plate in which the photosensitive resin as described above is provided on a support, such as an aluminum plate, is manufactured by processes such as degreasing of the support, graining, electrolytic polishing, anodizing, washing, drying, After a series of steps such as photosensitive liquid application, cutting, and surface inspection are completed, the device is placed vertically, for example, without interleaving paper, on the portable table shown in each of the above-mentioned examples.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to transport a large number of photosensitive printing plates, and it is suitable for transporting through narrow passages or over short distances.
