Definitions
- the subject of the invention is a tank intended for the automatic development in a suitable bath of positive and negative plates covered on at least one of their faces with a photosensitive layer, as is used in printing and particularly in offset.
- An advantageous method consists in circulating the plates in the bath while the latter is agitated by at least one ultrasonic generator.
- the plates are sometimes thin and relatively small in size; we can therefore make them follow without difficulty a curved passageway through the bath. But there are also rather rigid and large plates which it is impossible to curl.
- the bath used. has as low a volume as possible; Similarly, it is compulsory to avoid any loss of the bath when it is passed through by a rigid plate which cannot be curved.
- the main purpose of the invention is to provide a treatment tank in. a bath of minimum volume, agitated by ultrasound, of plates with photosensitive layer, flexible or rigid, crossing the bath without being curved, without loss of this bath.
- This goal is achieved from a tank intended to contain a developer bath for the development of photosensitive layer plates; equipped with an ultrasonic generator agitating this bath in which according to the invention there is an elongated rectilinear corridor of circulation of length less than the shortest plate limited by them said bath a lower wall and an upper wall containing between / without air pocket with an inlet opening at one end and an outlet opening at the opposite end, at least one flexible lip seal being arranged in one and in the other opening; support means are mounted, if necessary, between the lower wall and the upper wall at the level of the two openings, a bath tank is connected to the elongated corridor and placed in communication with the latter by a communication opening made in one any of the upper wall and the lower wall, this reservoir containing the ultrasonic generator.
- the bath tank is mounted directly above the upper wall or directly below the lower wall.
- the support means are spaced by free intervals in the direction of circulation of the plates through the bath.
- the lower wall is shaped like a container having along its edge a horizontal peripheral flange in the use position
- the upper wall is shaped like a container that is shallower than the lower container having also along its edge a horizontal peripheral flange in position of use
- the two tanks are assembled one on the other, a seal with flexible lip being interposed between the two peripheral flanges in the zone of the inlet and outlet area and a solid material seal is clamped between the two flanges outside of these areas.
- the bath tank is an integral part of one or the other tank by means of deep drawing or deepening formed in a part of this tank, preferably the downstream part in the direction of circulation of the plates.
- a bath tank is an integral part of one and the other tank.
- the supply to the tank takes place through a supply pipe which opens at the top of the upper tank.
- Support means are placed in the inlet opening and in the outlet opening, on the flange of the lower tank, and the lip seal is mounted between the peripheral flange of the upper tank and the support means. of each opening.
- the tank 1 illustrated in FIGS. 1 and 2 has an elongated rectilinear passage 2 for circulation of plates 3 to be treated, limited by a lower wall 4 and an upper wall 5; these two walls 4, 5 also limit between them an inlet opening 6 at one end and an outlet opening 7 at the opposite end.
- the distance between the two openings 6, 7 is chosen to be less than the length of the shortest plate to be treated.
- a first pair 8 of two drive rollers is placed opposite the inlet opening-6, parallel to it and a second pair 9 of drive rollers is placed in a similar manner opposite the outlet opening 7. Any plate 3 to be treated is engaged in the first pair 8 of rollers to be propelled by these through the inlet opening 6, then along the corridor 2, to take the outlet opening 7 and be gripped by the second pair of rollers 9.
- support means 10 are arranged in the elongated corridor 2, with a spacing in the direction of movement of the plates 3.
- These means 10 can be constituted by a simple plane carrier plate, or by a pleated or curved plate 7 ′′ so that it comes into contact only by transverse lines with the plates 3, or even by free rotating cylinders mounted transversely to the elongated corridor 2.
- support means 10 constituted by a simple flat support plate are arranged in the inlet opening 6 and in the outlet opening 7 to provide better guidance at the inlet and at the outlet and to provide a greater bearing surface for seals as will be explained later.
- the elongated corridor 2 is ° placed in communication with a bath tank 11; the communication takes place through a communication opening 12 preferably formed in the upper 5 and lower 4 walls, either in only one of these walls or in both, in their part close to the outlet opening 7.
- a ultrasonic generator 13 is arranged in the bath tank 11.
- the communication opening 12 is provided in the upper wall 5.
- a tank according to the invention is advantageously constituted by a lower tank having along its upper edge an outer peripheral flange 14 which is horizontal in the position of use.
- an upper container which is generally less deep than the lower container, also having an external peripheral flange 15 which is horizontal in the position of use. It is even possible, as can be seen in FIG. 1, that the upper wall 5 and the flange 14 are located in the same plane in the front part which follows the entry opening 6.
- the bath tank 11 appears following a deep-drawing or deepening in the rear part. It is therefore easy to reveal the bath tank 11 either on the upper tank (FIG. 1) which constitutes the upper wall 5 of the elongated channel 2, or on the lower tank (FIG. 3) which constitutes the lower wall 4, or on one and the other tray, on the two walls 4 and 5 of the elongated corridor 2 ( Figure 4).
- a tank 1 with one or two bath tanks 11, by assembling a lower tank with an upper tank set in opposite directions, using their peripheral flanges 14, 15, compressing them by means of bolts 1.6 , a seal 17 made of solid material, outside the zones of the inlet 6 and outlet 7 openings.
- a seal 18 with elastic lip 19 is placed.
- this seal 18 is fixed , for example by means of an adhesive, to the collar 15 of the upper tank.
- the elastic lip 19 then rests on the collar. 14 of the lower tank.
- two openings 6, 7 the lips 19 are directed in the direction of circulation of the plates 3 which lift them when entering and leaving the bath.
- the elongated corridor 2 is completely filled with bath between the two walls 4, 5 without air volume.
- the tank 1 comprises only one bath tank 11 incorporated in the upper tank (FIG. 1)
- the free level 20 of the bath can be in this tank and kept constant by means of a level detector 21.
- the arrival of the revealing bath is then made at the lower part of the tank 11, by a tube 22.
- the tank 1 comprises two tanks 11, the upper one and the 'other lower ( Figure 4); the free level 20, the level detector 21 and the supply pipe 22 are located on the upper tank.
- the tank 1 comprises a single lower tank 11 (FIG. 3)
- the tubing 22 for the arrival of the bath ends at the upper wall 5 of the tank.
- a drain pipe 23 is provided which starts from the lowest point of the lower tank or of the lower tank, when it exists, in the part of the tank close to the outlet opening 7.
- the ultrasound generator. 13 is commercially available. It is mounted in one or the other of the bath tanks 11, or in the two tanks 11 when it is envisaged to treat plates provided with a photosensitive layer on their two opposite faces.
