Description

[Detailed description of the invention] Name: Washing machine The present invention relates to a cleaning machine for cleaning a dampening roller.

A dampening roller is used in printing, especially offset printing, and is used to apply pressure to printing plates. used in offset printing to moisten the offset plate before applying ink It is something.

Such dampening rollers typically cover the liquid-retaining material, which is preferably fluffy. It consists of a rigid spindle with a ring fixed around it, and the printing The roller is mounted for rotation in a machine.

However, this invention consists of a spindle and a liquid retaining material covering. Also applicable to cleaning machines that clean other rollers, including those described below as dampening rollers. be done.

Known cleaning machines include a cleaning roller with a grooved surface that is rotatably mounted on the machine frame. at least one cleaning roller, such as a roller. 1 or 2 bottles of dampener Place the roller along the entire length of the dampening roller, parallel to it, and in contact with the cleaning roller. As such, a receiving means for receiving the machine frame is provided. If a cleaning liquid such as water is used, e.g. , either alone or from a dampening roller, by spray means also mounted on the machine frame. Facilitates the removal of ink or anything else that needs to be washed off the roller. It is supplied together with the chemical agent, and comes into contact with the cleaning roller as it rotates. The grooves provided on the surface of the cleaning roller will rotate the dampening roller. Perform a scraping action for cleaning.

After cleaning, remove the liquid covering the spindle of the dampening roller or each dampening roller. The retaining material must be partially dried before the dampening roller can be used again. Ru.

It is very time consuming and in any case the liquid retaining material capacity of the roller is from simple dampening rollers that cannot be guaranteed to remove sufficient liquid from the baling. Various means have been proposed for drying the rollers rather than treating them with water.

First of all, the roller is manually wiped dry, but the covering of the O-ra is Since this holds a large amount of liquid, the operator must be careful when performing this work. Become better. Therefore, this is not satisfactory.

Second, auxiliary drying means are provided, which bring the dampening roller into contact with the cleaning roller. from the drying position to the dryer, where the rollers are rotated. It is placed under the action of an auxiliary drying means that simply moves to the side. Since the method is slow, this Not satisfied.

It is therefore an object of the invention to provide a new or improved cleaning machine. It's in the country.

According to one aspect of this invention, we provide a rotatable cleaning roller, a dampening roller. means for installing the cleaning D-ra parallel to and in contact with the cleaning D-ra; As the cleaning roller rotates, cleaning fluid is supplied to the dampening roller to clean the dampening roller. a cleaning liquid supply means for removing at least a portion of the cleaning liquid from the dampening roller; The drying means includes a support and a drying member mounted on the support. and the drying member is adapted to engage a dampening roller that is in contact with a cleaning roller. A cleaning machine is provided which is movable along a support.

The cleaning roller is rotated (both of which give rotation to the dampening roller. Thus, the dampening roller is rotated. As the dampening roller rotates with the drying member with which it is engaged, the liquid in the dampening roller The liquid retained by the retaining covering is squeezed between the drying member and the dampening roller. It is removed by the oxidation action.

The drying element can be used to squeeze the dampener or to achieve the required degree of drying. attached to the support so as to be able to control the movement of the drying member to the rollers; It is preferable that the

For example, the drying member is pivoted to the support.

The support is preferably long and extends parallel to the cleaning roller so that the drying member is not damp. The roller is movable along the support from one end to the other.

Conveniently, the support is a D-rad fixed to the washing roller. Bear Arin A dampening roller is provided between the drying member and the support to allow access to or removal from the dampening roller. And, suitably, movement along the support is facilitated.

The mechanism according to the invention provides high speed as well as efficient drying of the dampening roller. It was found that "3Q-ra" overwhelms many of the drawbacks of previous methods of drying. , the rollers can be dried without removing them from the cleaning machine, and the operator can Additionally, the wet, heavy dampening roller can be lifted and transferred to an auxiliary drying means. There's no need to.

One or more dampening rollers are installed parallel to each other and in contact with the cleaning roller. When placed in a machine, the drying part will dry out the moisture in the machine. It has been found that it is sufficient to contact only one dampening roller per step. this As all the rollers rotate, incorrect rotation will cause rotation from the cleaning rollers. Since the rotation of is transferred via the cleaning roller to the dampening roller which is in contact with the drying member and thus , all of the dampening rollers can be dried to approximately the same degree.

The cleaning machine is provided with at least two separate receiving means, each containing a damp O- In order to install the roller parallel to and in contact with the cleaning roller, its end or It is designed to be received near the end.

The receiver means moves the dampening roller by gravity into contact with the cleaning roller.

The support of the drying means is placed on the frame of the machine in which the washing rollers and receiving means are provided. Although it can be done, the receiver is attached by means.

It is preferable that the support and the drying member are freely removable from the rest of the machine; The rollers can be cleaned in the machine without the presence of drying means.

For example, a receiver is a holding type in which each of the means holds the support at or near its end. The support and the drying member II hold the support in the receiving means.

The drying member comprises a first portion in contact with the dampening roller and a second manual engagement portion. manually applying pressure to the second section of the roller to bring the first section closer to the dampening roller. The squeezing action of the drying member on the dampening roller and, therefore, the dampening roller This increases the degree of dryness.

Preferably, the machine is provided with only one cleaning roller; has a surface with a large number of spiral peripheral grooves, and the dampening roller or is adapted to contact one of the cleaning rollers.

In such machines, water is transferred to the wash roller or other dampening roller within the machine. For liquids to be removed from the dampener D-ra that come into contact with the drying element without being rehydrated. There is sufficient space. each in contact with one or two dampening rollers. A cleaning machine with multiple cleaning rollers in contact with the drying member The water removed from the roller simply transfers to the other dampening rollers in the machine and therefore It suffers from the disadvantage that the body's removal rate is impaired.

The washing machine preferably has a frame in which a washing roller and a dampening roller are provided. and the frame further includes a sump for collecting water removed from the dampening roller. Ru.

Further, the machine dries the dampening roller or dampening rollers, respectively, as described above. Before using the drying means to Means is provided for supplying cleaning liquid to each.

For example, spray means are provided for spraying the cleaning liquid onto the dampening roller.

According to a second aspect of the invention we provide that the drying means can be engaged with the machine. a support, and a device attached to the support, moved along the support, and received by the machine. The invention comprises a dampening roller or a drying member in contact with one of the dampening rollers. A first aspect provides drying means for a washing machine.

This can be achieved by spraying water or a cleaning liquid onto the dampening roller 17,18. normally In this example, a dampening roller 17 used for offset printing is contaminated with ink. ．． 18 is first sprayed with water from tube 15 and then chemical agent is applied. roller 17.18 to facilitate ink removal and then to roller 17.18. is again sprayed with water to remove chemicals and ink from rollers 17.18. Therefore, normally during this time, the rollers 17, 18 are rotating.

After cleaning, drying means 30 are mounted on the cleaning machine to dry the rollers 17,18. It is. The drying machine 30 consists of only a support 31 which is a long rod and a dampening roller 17. and a drying member 32 that moves in the direction and comes into contact with the drying member 32.

Each of the receiver members 21 has a pair of abutting members 33 on their upper surfaces, and these The end or proximal portion of the support rod 31 is held therebetween. Thus, the dry section The material 30 can be easily removed, and the weight 1 of the rod 31 and drying member 32 is Hold the steps in place. During such washing, the drying means 30 preferably be removed from the machine and the lid, e.g. The operator may be protected while water is being sprayed from tube 15. stomach.

The drying member 32 includes a first member 36 that contacts the roller 17 during use; and a second member affixed to the handle 38. The drying member 32 As shown by arrow B in FIG. 2, it is pivotable relative to the rod 31. Han The pressure applied to the drying member 32 via the needle 38 can thus be made variable. I can do it. As the roller 17 rotates, the roller 17 36 to dry the O-ra 17.

To facilitate pivoting movement of the drying member 32 relative to the support rod 31, the drying A bearing (not shown) may be provided between member 32 and rod 31.

The drying member 32 is also movable in the length direction of the rod 31 as shown by arrow C in FIG. It is. The dampening roller 17 thus moves the drying member 32 along the rod. By doing so, it is gradually dried from one end to the other.

During this operation, not only the dampening roller 17 is dried, but also the dampening roller 17 is dried. The water retained by the covering 20 of 18 flows through the cleaning roller 12 roller 17 and thus roller 18 is the roller in contact with drying member 32. It is dried to about the same extent as 17.

As shown, the machine is equipped with only two dampening rollers 17.18. only. Actually, the third roller is also attached to the abutting member 25 on the cleaning roller 12. It is received by a receiving member 21 in between. In the drawing, this roller is simply This is excluded because it is

Various modifications may be made without departing from the scope of this invention.

For example, a single cleaning roller 12 with which each dampening roller 17,18 of the machine contacts This ensures sufficient space for the water removed from the roller 17 to fall into the reservoir 10. However, if a large number of cleaning rollers 12 are installed, other moisture generated in the machine If possible, ensure that there is no return of water to the washing or cleaning rollers. However, if necessary, a large number of cleaning rollers 12 and just one or three or more Scraping rollers 17,18 may also be provided.
