[Industrial applications]

 The present invention relates to a roll finishing machine for finishing washed sheets and the like, and in particular, performs waxing, which is necessary for maintenance management of the finishing treatment process, in a short time, efficiently, evenly, reliably and safely. It is related to a roll finishing machine.

[0002]

[Prior Art]

 In general, a roll finishing machine is provided with a compression roll and a heating bed facing each other, and the washed finish product is passed between the compression roll and the heating bed to wash the washed finish product. Is finished. However, in this roll finishing machine, when glue or the like adheres to or accumulates on the surface (iron surface) of the heating bed, the object to be processed is curled or wrinkles occur on the object to be processed, and There is a problem such as the finish processing condition is bad. Therefore, in the finishing process in such a roll finishing machine, it is necessary to carry out waxing work as an important work for performing maintenance management for giving sufficient gloss and finish to the object to be finished. That is, waxing work is indispensable to make the surface of the heating bed of the roll finishing machine slippery, prevent adhesion of glue and the like on the surface of the heating bed, and reduce the driving force of the compression roll. I need to do it. In the conventional wax finishing work in the roll finishing machine described above, first, the operation of the roll finishing machine is stopped, a cloth for wax cloth is spread on the feeding belt of the roll finishing machine, and placed on the cloth. Flake-shaped or granular solid wax is sprinkled, and the above-mentioned cloth is folded in two so as to cover the solid wax. Next, the heating bed of the roll finishing machine is heated and the roll finishing machine is operated at a low speed, and the two-folded cloth covered with the above-mentioned solid wax is passed between the heating bed and the compression roll. Then, the solid wax melts and permeates the cloth. A cloth in which the solid wax is melted and soaked is generally called a wax cloth. When the above wax cloth is passed between the pressing roll of the roll finishing machine and the heating bed, the wax soaked in the cloth is melted by the heat and is applied to the surface of the heating bed. As a result, it is possible to improve the slippage of the surface of the heating bed and prevent adhesion of glue or the like on the surface of the heating bed, so that it is possible to improve the finish quality of the object to be processed, Also, the driving force of the compression roll can be reduced.

[0003]

[Problems to be solved by the device]

 The waxing operation described above is generally performed every 1 to 2 hours. However, the width of the wax cloth should be narrower than the width of the roll finishing machine (the width of the compression roll and the heating bed) so that the worker can handle it easily. For this reason, it is necessary to pass the wax cloth between the heating bed and the compression rolls several times in one waxing operation so that the wax spreads over the entire width of the roll finishing machine. The work takes about 3 to 5 minutes. Therefore, for example, when the roll finishing machine is operated for 8 hours a day and waxing is performed every hour, the maximum time required for the waxing is 40 minutes per day. As described above, since the conventional roll finishing machine performs waxing work using a wax cloth, the waxing work takes a long time, and during the waxing work, the material to be finished is processed. The finishing process cannot be performed, and the finishing process is inefficient. Further, in the conventional roll finishing machine, since the wax cloth is passed between the heating bed and the compression roll, the temperature of the wax cloth immediately after passing between the heating bed and the compression roll becomes high, so that the worker is burned. There is a risk that the wax cloth may ignite or the wax cloth may ignite spontaneously. In addition, the conventional roll finishing machine uses a wax cloth that has been manually sprayed with solid wax and impregnated with heat, resulting in unevenness in areas where the solid wax is sprayed in many areas or in small areas. Mura occurs where the cloth is heavily impregnated with wax and where it is not. Therefore, there is a problem that it is difficult to uniformly apply the wax to the surface of the heating bed of the roll finishing machine.

An object of the present invention is to provide a roll finishing machine that can perform waxing work efficiently, in a short time, reliably and evenly, and safely.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a nozzle that sprays liquid wax uniformly over the entire width of the compression roll, and connects a liquid wax supply device that supplies liquid wax to the nozzle. Characterize.

[0006]

[Action]

 In the present invention, the liquid wax can be sprayed onto the pressure roll from the nozzle, and the pressure roll can be rotated to transfer and apply the liquid wax sprayed onto the pressure roll onto the surface of the heating bed. Therefore, by using a nozzle that sprays the liquid wax onto the pressure roll uniformly over the entire width of the pressure roll, the wax is applied to the surface of the heating bed over the entire width with one spray of liquid wax. can do. Moreover, when the finished product is sent to the roll finishing machine, the liquid wax is not directly sprayed onto the finished product, or the liquid wax sprayed on the compression roll is not directly applied onto the finished product. To the extent, it is only necessary to make an interruption to open between the preceding work piece and the subsequent work piece. As a result, the time for waxing work can be shortened as a whole, and the efficiency of finishing work can be improved. Further, since the operator does not handle the high temperature wax cloth by using the nozzle and the liquid wax supply device instead of the wax cloth, there is no risk of the operator being burned. Moreover, since no wax cloth is used, there is no risk that the high-temperature wax cloth will ignite spontaneously. Further, by using a nozzle capable of spraying the liquid wax on the compression roll uniformly over the entire width of the compression roll, the liquid wax sprayed uniformly on the compression roll is evenly distributed on the surface of the heating bed. Can be applied.

An unloading conveyor device (not shown) for receiving is installed. The automatic folding machine or the carry-out conveyor device is equipped with a shape monitoring device (not shown). As the above-mentioned shape monitoring device, the one previously filed by the present applicant (Japanese Patent Application No. 1-194255) or the like is used. This shape monitoring device monitors and judges the finish processing state of the finish processing object finished by the roll finishing machine 1 by the shape of the finish processing object, and when the finish processing is defective, the finish processing failure signal Is output.

In FIGS. 1 to 3, reference numeral 8 is a pipe for spraying a liquid wax. The pipe 8 is arranged substantially in the middle of the compression roll 3 of the first stage and the compression roll 4 of the second stage, above the compression rolls 3 and 4, and in parallel with the compression rolls 3 and 4. It is set up. The pipe 8 is connected to a liquid wax tank 11 via a solenoid valve 9 and a pump 10. The pipe 8, the solenoid valve 9, the pump 10 and the liquid wax tank 11 constitute a liquid wax supply device. 1 to 3, reference numeral 12 is a nozzle attached to the pipe 8. The nozzle 12 is arranged so that the liquid wax can be sprayed uniformly on the first-stage compression roll 3 and the second-stage compression roll 4 over the entire width thereof.

FIG. 4 shows a system diagram of a liquid wax spray device for a roll finisher of the present invention in this embodiment. In the figure, 13 is a shape monitoring device equipped on an automatic folding machine or an unloading conveyor device installed on the exit side of the roll finisher. The shape monitoring device 13 outputs a finish processing failure signal 14 when the finish processing state of the finish processing object finished by the roll finishing machine 1 is poor. Reference numeral 15 is a counting circuit, and 16 is a count number setting device for outputting a set count number 17 to the counting circuit 15. The counting circuit 15 counts the finish processing failure signal 14 from the shape monitoring device 13 continuously or within a set time, and the count number of the finish processing failure signal 14 is set by the count setter 16. When the constant count number 17 is reached, a start signal 18 for starting the spraying work is output. The set count number 17 in the count number setting device 16 which is the basis of the output of the start signal 18 from the above-mentioned count circuit 15 may be one or plural, and depends on the adhered state of glue or the like of the roll finishing machine 1. .. That is, the degree is such that glue or the like adheres to and deposits on the heating beds 5 and 6 of the roll finishing machine 1 to cause defects in the finishing treatment of the roll finishing machine 1 or to frequently cause such defects.

Reference numeral 19 is an alarm device. In this example, it is a buzzer or a signal lamp, or a buzzer and a signal lamp. The alarm device 19 is activated (ON) by the activation signal (signal for activating the alarm device) 18 from the counting circuit 15 and stopped (OFF) after the elapse of the set time T1 to spray the operator. Notify the start and stop of work. The operation set time T1 of the alarm device 19 is set by a timer or the like, and is almost equal to the sum of the spray delay set time T3 and the spray time T4 which will be described later. Reference numeral 20 is an inserter such as a sheet spreading inserter. The loading interval of the loading machine 20 is set so as to load the object to be processed as close as possible to the previously processed object to be processed in a range where the next object to be processed does not overlap. Then, the operation is temporarily stopped (OFF) by the activation signal (signal for reducing the number of inserted sheets) 18 from the counting circuit 15, and the operation is restarted (ON) after the elapse of the set time T2 to perform the above-mentioned finishing. It is intended to widen the interval of feeding the processed material. By widening the interval between the objects to be processed by the throwing machine 20, the liquid wax is sprayed on the pressing rolls 3 and 4 between the preceding and following objects to be processed, and the pressing is performed. Liquid wax sprayed on rolls 3 and 4 can be applied to the heated beds 5 and 6. That is, the spraying operation can be performed so as not to spray the liquid wax directly on the object to be processed or to apply the liquid wax sprayed on the pressing rolls 3 and 4 to the object to be processed. The time interval T2 for setting the feeding interval of the object to be processed of the throwing machine 20 is set by a timer or the like, and as described above, the liquid wax is directly sprayed or pressed onto the object to be processed. The liquid wax sprayed on the rolls 3 and 4 should not be applied to the object to be finished.

Reference numeral 21 is a spray delay timer. The spray delay timer 21 is activated (ON) by a start signal (a signal for starting the timer operation) 18 from the counting circuit 15, and after a set time T3 has elapsed, the timer is stopped and the operation is stopped (OFF). This is to delay the spraying start time. By delaying the spraying start time with this spray delay timer 21, the spraying work is delayed until the material to be finished that has already been put into the roll finishing machine 1 passes the spraying point or the coating point of the liquid wax. Thus, it is possible to prevent the liquid wax from being sprayed or applied directly to the object to be processed. The set time T3 of the spray delay timer 21 is set such that the liquid wax is not directly sprayed or applied to the object to be processed.

Reference numeral 22 is a spray time timer. The spray time timer 22 is activated (ON) by a start signal (a signal for starting the timer operation) 23 output by the time-out of the spray delay timer 21, and a spray work start signal (a solenoid valve 9 is opened). Signal and pump 10 operation signal) 24 to the solenoid valve 9 and pump 10, and after the set time T4 has elapsed, the operation is stopped (OFF), and the spray work stop signal (solenoid valve 9 close signal). And a pump 10 operation stop signal) 25 to the solenoid valve 9 and the pump 10. The set time T4 of the spray time timer 22 is set so that the liquid wax is sprayed onto the pressing rolls 3 and 4 and is sufficiently applied from the pressing rolls 3 and 4 to the heating beds 5 and 6.

The roll finisher of the present invention in this embodiment has the above-mentioned structure. The liquid wax spraying operation will be described below with reference to the time chart of FIG. First, glue or the like adheres to and deposits on the heating beds 5 and 6 of the roll finishing machine 1, which causes a failure in the finishing process of the roll finishing machine 1 or a frequent occurrence of such failures. When the count number of the finish processing failure signal 14 from the shape monitoring device 13 reaches the set count number 17, the start signal 18 is output. Then, the alarm 19 is activated to notify the operator of the start of spraying work. At the same time, the operation of the loading machine 20 is stopped and the loading interval of the finished products is widened. At the same time, the spray delay timer 21 is activated to delay the spray work start time. Then, when the object to be finished that has already been put into the roll finishing machine 1 has passed through the spray spot or the coating spot, the above-mentioned spray delay timer 21 is timed up, and at the same time, the spray time timer 22 is activated, The spray operation start signal 24 is output. Then, the solenoid valve 9 is opened, and the pump 10 is operated so that the liquid wax passes through the tank, the pump, the solenoid valve, the spray pipe, and the nozzle, and then spreads over the compression rolls 3 and 4 to the full width of the compression rolls 3 and 4. Sprayed over. Further, the liquid wax sprayed on the pressing rolls 3 and 4 is transferred and applied to the heating beds 5 and 6. During this spraying operation, the throwing machine 20 restarts its operation, and when the spraying operation is performed for the set time T4, the spraying time timer 22 is timed up and the spraying operation stop signal 25 is output. .. Then, the solenoid valve 9 is closed, the operation of the pump 10 is stopped, and the spraying work is stopped. On the other hand, the wax is directly sprayed or applied to the object to be processed put into the roll finishing machine 1. There is no such a case, and the object to be processed is finished by the roll finishing machine 1. At the same time when the spraying work is stopped, the alarm device 19 is deactivated and the operator is notified of the stop of the spraying work.

As described above, in the roll finishing machine of the present invention in this embodiment, the liquid wax is uniformly sprayed from the nozzle 12 onto the pressing rolls 3 and 4 over the entire width, so that the pressing rolls 3 and 4 are sprayed on the pressing rolls 3 and 4. The sprayed liquid wax can be uniformly applied to the surfaces of the heating beds 5 and 6 over the entire width. In addition, when the processed product is sent to the roll finishing machine 1, the liquid wax is directly sprayed on the processed product or the liquid wax sprayed on the compression rolls 3 and 4 is directly processed on the processed product. In order to prevent it from being applied to the substrate, it is sufficient to interrupt the gap between the preceding processed product and the succeeding processed product. As a result, the waxing work time can be shortened as a whole, and the efficiency of the finishing treatment can be improved. Further, since the nozzle 12 and the liquid wax supply devices 9 and 10 are used instead of the wax cloth, the worker does not handle the high temperature wax cloth, so that there is no risk of the operator being burned. .. Moreover, since no wax cloth is used, there is no risk that the high-temperature wax cloth will ignite spontaneously. Further, by using the nozzle 12 capable of spraying the liquid wax onto the compression rolls 3 and 4 uniformly over the entire width, the liquid wax sprayed on the compression rolls 3 and 4 is heated to the heating beds 5 and 6. It can be evenly applied to the surface of.

FIG. 6 is a side view showing a modified example of the nozzle 12 and the spray pipe 8 of the roll finishing machine of the present invention. In this example, the two spray pipes 8 and 8 are arranged above the first-stage compression roll 3 and the second-stage compression roll 4, respectively. The nozzle 12 is attached to the compression roll 3 of the first stage and the compression roll 4 of the second stage so that they can be sprayed over the entire width, respectively, and is the same as that of the first embodiment described above. The effect of can be achieved.

FIG. 7 shows another system diagram of the liquid wax spray device of the roll finisher of the present invention. The system shown in FIG. 7 includes a shape monitoring device 13 that detects a defect in the finish processing state of the object to be processed of the system shown in FIG. 4 and outputs a detection signal thereof, and the shape monitoring device 13 Instead of the counting circuit 15 which counts the finish processing failure signal and outputs a start signal when the count number reaches the set count number, the number of the finished products to be washed is counted and the count number is set. A count circuit 150 is provided which outputs a start signal when the number reaches. This system determines whether or not wax spraying is necessary depending on the number of finished sheets (for example, 1000 or 2000 sheets). Even in this case, it is possible to sufficiently achieve the intended purpose without causing a defect in the finish processing state of the product to be processed. Moreover, there is an effect that the expensive shape monitoring device 13 is unnecessary.

Although the roll finishing machine 1 equipped with the two compression rolls 3 and 4 and the two heating beds 5 and 6 has been described in the above embodiment, the roll finishing machine of the present invention is It may be equipped with one compression roll and one heating bed, or with three or more compression rolls and three or more heating beds.

In the above-described embodiment, the spraying operation start means is an automatic type including the shape monitoring device 13, the count circuit 15, the count number setting device 16, and the like, but the operator arbitrarily performs the operation. It may be manual. Further, although the start and stop of the operation of the spray work means, that is, the throwing machine 20, the spray devices 9 and 10, etc. are automatically performed by the timers 21 and 22, etc., they may be manually performed by the operator. It is also good. Further, the starting means is automatic and the spraying means is manual, the starting means is manual and the spraying means is automatic, the starting means is manual and the spraying means is manual, and the combination is free. ..
