Technical Field

The present invention relates to a defiberized product manufacturing apparatus that generates a defiberized product suitable for manufacturing paper (sheet), and a sheet manufacturing apparatus equipped with the defiberized product manufacturing apparatus.

Background

Conventionally, there is known a sheet manufacturing apparatus that removes an adhering substance adhering to a conveying section by inserting a removing member into the conveying section (for example, see patent document 1).

However, in the above-described apparatus, there is a problem that when the removing member is inserted into the conveying section, the operation rate of the apparatus is lowered because the production of the sheet needs to be stopped.

Disclosure of Invention

The present invention has been made to solve at least part of the above-described problems, and can be implemented as the following modes or application examples.

Application example 1

The defibrination product manufacturing apparatus according to the application example includes: a defibration unit that defibrates a raw material containing fibers to produce a defibrated product; a raw material supply unit that supplies the raw material to the defibration section; a monitoring unit; a cleaning unit, wherein the raw material supply unit comprises: a conveying unit that conveys the raw material; a storage unit that stores the raw material conveyed from the conveying unit and supplies the raw material to the defibrating unit; and a measuring unit that measures a state of the raw material stored in the storage unit, wherein when a transport speed of the raw material in the raw material supply unit is slower than that in a normal operation, the monitoring unit predicts a stagnation in transport of the raw material in the raw material supply unit and activates the cleaning unit, and the cleaning unit performs a cleaning process for preventing the stagnation in advance with respect to at least one of the transport unit and the storage unit.

When the conveyance speed of the raw material in the raw material supply unit (conveyance unit, storage unit) is slower than that in the normal operation, the monitoring unit predicts the stagnation of the conveyance of the raw material in the raw material supply unit, and the cleaning unit performs the cleaning process for preventing the stagnation of the conveyance of the raw material in advance. In addition, when the stagnation of the conveyance of the raw material is predicted, the deterioration state of the raw material supply unit becomes slight as compared with the case where the stagnation of the conveyance of the raw material occurs, and the raw material supply unit can be returned to the normal state in a short time, thereby shortening the stop time of the apparatus (the time during which the defibrinated object cannot be produced).

Therefore, compared to a configuration in which the problem of the stagnation of the conveyance of the raw material is prevented in advance, and a configuration in which the problem of the stagnation of the conveyance of the raw material is eliminated, the time during which the defiberized material cannot be produced is shortened, and the time during which the defiberized material can be produced is lengthened, thereby improving the efficiency (operating rate) of the apparatus.

In the following description, the stop of the conveyance of the raw material may be simply referred to as the stop of the conveyance.

Application example 2

In the defibrinated product manufacturing apparatus according to the application example, it is preferable that the cleaning unit includes a nozzle that ejects a fluid, and the cleaning process is a process in which the fluid is ejected from the nozzle to at least one of the transport unit and the storage unit.

For example, in the case where the stagnation of the conveyance in at least one of the conveyance unit and the storage unit is predicted, when the fluid is ejected from the nozzle of the cleaning unit to at least one of the conveyance unit and the storage unit to remove the cause (foreign matter, dirt, etc.) causing the stagnation of the conveyance, the stagnation of the conveyance in at least one of the conveyance unit and the storage unit can be prevented.

Application example 3

In the defibrinated product manufacturing apparatus according to the application example, it is preferable that the measuring unit measures the weight of the raw material stored in the storage unit and a time until the weight of the raw material reaches a predetermined amount, and the monitoring unit activates the cleaning unit when the time exceeds a predetermined value.

The retention section retains the raw material conveyed from the conveying section, and supplies a predetermined amount of the raw material to the defibration section, for example. The measuring section measures the state of the raw material (for example, the weight of the raw material) stored in the storage section. When a predetermined amount of the raw material is stored in the storage portion, the predetermined amount of the raw material is supplied from the storage portion to the defibration portion.

In the textile product manufacturing apparatus having the above-described configuration, if a phenomenon occurs in which the raw material is difficult to be supplied from the conveying unit to the storage unit, the time for storing a predetermined amount of the raw material in the storage unit becomes long. In addition, if the phenomenon that the raw material is difficult to be supplied from the conveying section to the storage section deteriorates, the conveyance is stopped, and the raw material cannot be supplied from the conveying section to the storage section.

Therefore, when the time until the weight of the raw material stored in the storage section reaches the predetermined amount is measured and the time until the weight of the raw material stored in the storage section reaches the predetermined amount is increased, it can be determined that the phenomenon in which the raw material is difficult to supply from the conveying section to the storage section occurs, and it is possible to grasp the precursor of the stagnation of the conveyance and predict the stagnation of the conveyance. Therefore, when the time until the weight of the raw material stored in the storage section reaches the predetermined amount exceeds a predetermined value, that is, when the time until the weight of the raw material stored in the storage section reaches the predetermined amount becomes long, the stagnation of the conveyance is predicted, and therefore, it is preferable that the monitoring section activates the cleaning section to perform the cleaning process for preventing the stagnation of the conveyance from occurring.

Application example 4

In the defibrinated product manufacturing apparatus according to the application example, it is preferable that the measurement unit measures the weight of the raw material newly stored in the storage unit and a time from when the raw material is newly stored in the storage unit, and the monitoring unit activates the cleaning unit when the weight of the raw material newly stored in the storage unit does not reach a predetermined value after a predetermined time elapses.

The retention section retains the raw material conveyed from the conveying section, and supplies a predetermined amount of the raw material to the defibration section, for example. The measuring unit measures the state of the raw material (for example, the weight of the raw material) newly stored in the storage unit when a predetermined time has elapsed. When a predetermined amount of the raw material is stored in the storage portion, the predetermined amount of the raw material is supplied from the storage portion to the defibration portion.

In the defibrinated product manufacturing apparatus having the above-described configuration, if a phenomenon occurs in which it is difficult to supply the raw material from the conveying section to the storage section, the raw material newly stored in the storage section becomes lighter when a predetermined time has elapsed. In addition, if the phenomenon that the raw material is difficult to be supplied from the conveying section to the storage section deteriorates, the conveyance is stopped, and the raw material cannot be supplied from the conveying section to the storage section.

Therefore, the measurement unit measures the weight of the raw material newly stored in the storage unit and the time from when the raw material is newly stored in the storage unit, and when the weight of the raw material newly stored in the storage unit does not reach a predetermined value after the elapse of a predetermined time, for example, when the weight of the raw material newly stored in the storage unit becomes light within the predetermined time, the monitoring unit can determine that a phenomenon in which the raw material is difficult to be supplied from the conveying unit to the storage unit occurs, and can grasp a precursor of the stoppage of the conveyance and predict the stoppage of the conveyance.

Therefore, since the stagnation of the conveyance is predicted when the weight of the raw material newly stored in the storage unit does not reach the predetermined value when the predetermined time has elapsed, that is, when the weight of the raw material newly stored in the storage unit becomes light when the predetermined time has elapsed, it is preferable that the monitoring unit activates the cleaning unit to perform the cleaning process for preventing the stagnation of the conveyance from occurring.

Application example 5

In the defiberized product manufacturing apparatus according to the application example, it is preferable that the raw material supply unit includes a first raw material supply unit and a second raw material supply unit, and when the monitoring unit predicts the stagnation in the first raw material supply unit while the raw material is being supplied to the defiberizing unit by the first raw material supply unit and the second raw material supply unit, the raw material supply unit stops only the supply of the raw material by the first raw material supply unit, and after the cleaning process for the first raw material supply unit is performed, the supply of the raw material by the first raw material supply unit is restarted, and when the monitoring unit predicts the stagnation in the second raw material supply unit while the raw material is being supplied to the defiberizing unit by the first raw material supply unit and the second raw material supply unit, the supply of the raw material by the second raw material supply unit is stopped only, and after the cleaning process for the second raw material supply unit is performed, the supply of the raw material by the second raw material supply unit is restarted.

When the monitoring unit predicts that the conveyance of the first raw material supply unit is stopped during the supply of the raw material to the defibration unit by the first raw material supply unit and the second raw material supply unit, if the cleaning process is performed on the first raw material supply unit by stopping only the supply of the raw material by the first raw material supply unit and not stopping the supply of the raw material by the second raw material supply unit, the time required for producing the defibered product becomes longer than the case where the cleaning process is performed by stopping both the first raw material supply unit and the second raw material supply unit, and the efficiency (operating rate) of the apparatus can be improved.

When the monitoring unit predicts that the conveyance of the second raw material supply unit is stopped during the supply of the raw material to the defibration unit by the first raw material supply unit and the second raw material supply unit, if the cleaning process for the second raw material supply unit is performed by stopping only the supply of the raw material by the second raw material supply unit without stopping the supply of the raw material by the first raw material supply unit, the time required for producing the defibered product becomes longer than the case where the cleaning process is performed by stopping both the first raw material supply unit and the second raw material supply unit, and the efficiency (operating rate) of the apparatus can be improved.

Application example 6

In the defibrinated object manufacturing apparatus according to the application example, it is preferable that the apparatus further includes a notification unit that notifies that the time exceeds the predetermined value after the cleaning process is performed on the first raw material supply unit and the supply of the raw material by the first raw material supply unit is restarted, or that the time exceeds the predetermined value after the cleaning process is performed on the second raw material supply unit and the supply of the raw material by the second raw material supply unit is restarted, or that the notification unit notifies that the weight of the raw material newly stored in the storage unit does not exceed the predetermined value after the predetermined time has elapsed.

When the monitoring unit predicts that the conveyance in the first raw material supply unit is stopped, performs the cleaning process for the first raw material supply unit, and restarts the supply of the raw material by the first raw material supply unit, and the time until the weight of the raw material reaches the predetermined amount exceeds a predetermined value, it can be determined that the cause (foreign matter, dirt, etc.) causing the conveyance stop has not been appropriately eliminated.

Further, after the monitoring unit predicts the stoppage of the conveyance in the first raw material supply unit, performs the cleaning process for the first raw material supply unit, and restarts the supply of the raw material by the first raw material supply unit, if the weight of the raw material newly stored in the storage portion does not exceed the predetermined value after the predetermined time has elapsed, it can be determined that the cause (foreign matter, dirt, etc.) causing the stoppage of the conveyance has not been appropriately eliminated.

When the monitoring unit predicts that the conveyance in the second raw material supply unit is stopped, performs the cleaning process for the second raw material supply unit, and restarts the supply of the raw material by the second raw material supply unit, and the time until the weight of the raw material reaches the predetermined amount exceeds the predetermined value, it can be determined that the cause (foreign matter, dirt, etc.) causing the conveyance stop has not been appropriately eliminated.

Further, after the monitoring unit predicts the stoppage of the conveyance in the second raw material supply unit, performs the cleaning process for the second raw material supply unit, and restarts the supply of the raw material by the second raw material supply unit, if the weight of the raw material newly stored in the storage portion does not exceed the predetermined value after the predetermined time has elapsed, it can be determined that the cause (foreign matter, dirt, etc.) causing the stoppage of the conveyance has not been appropriately eliminated.

Since the notification unit notifies that the cause of the stagnation of the conveyance has not been appropriately eliminated, the worker can quickly grasp that the cause of the stagnation of the conveyance has not been appropriately eliminated and can quickly perform a treatment for eliminating the cause of the stagnation of the conveyance.

Application example 7

In the defiberized product manufacturing apparatus according to the application example, it is preferable that the raw material supply unit includes a first raw material supply unit and a second raw material supply unit, and when the monitoring unit predicts the stagnation in the first raw material supply unit while the raw material is supplied to the defiberizing unit by the first raw material supply unit, the cleaning process with respect to the first raw material supply unit is performed after switching to supply the raw material to the defiberizing unit by the second raw material supply unit.

If the monitoring unit detects that the conveyance of the first raw material supply unit is stopped while the first raw material supply unit supplies the raw material to the defiberizing unit, and then performs the cleaning process on the first raw material supply unit after switching to supply the raw material to the defiberizing unit by the second raw material supply unit, the cleaning process is performed while the supply of the raw material to the defiberizing unit is continued.

Application example 8

In the defiberized product manufacturing apparatus according to the application example, it is preferable that the cleaning process with respect to the second material supplying unit is performed after the raw material is supplied to the defiberizing unit by the first material supplying unit that has performed the cleaning process, in a case where the monitoring unit predicts the stagnation in the second material supplying unit after the switching to the supply of the raw material to the defiberizing unit by the second material supplying unit.

Since the cleaning process is performed on the second raw material supply means after the supply of the raw material to the defibration section by the first raw material supply means is switched to the supply of the raw material to the defibration section if the monitoring section detects that the conveyance of the raw material by the second raw material supply means is stopped during the supply of the raw material to the defibration section by the second raw material supply means, the cleaning process is performed while the supply of the raw material to the defibration section is continued, and therefore, the time for manufacturing the defiberized product becomes longer than the time for performing the cleaning process while the supply of the raw material to the defibration section is stopped, and the efficiency (operating rate) of the apparatus can be improved

Application example 9

In the defibrinated product manufacturing apparatus according to the above application example, preferably, the raw material includes waste paper.

Even when waste paper is used as a raw material, the efficiency (operating rate) of a defibrinated product manufacturing apparatus that defibrinates the waste paper to produce a defibrinated product can be improved.

In the defibrination product manufacturing apparatus described in the above application example, cleaning processing is performed to prevent stagnation of conveyance from occurring, so that the time for manufacturing defibrination products is prolonged, and the efficiency (operating rate) of the apparatus is improved. Therefore, in the sheet manufacturing apparatus equipped with the defibrator manufacturing apparatus according to the above application example, the time required for manufacturing the sheet is also increased, and the efficiency (operation rate) of the apparatus is improved.

In a sheet manufacturing apparatus including a defibrator manufacturing apparatus having an improved efficiency (operation rate), a mixing section for mixing a defibrator and a resin supplied from the defibrator manufacturing apparatus, a web forming section for forming a web from the mixture of the defibrator and the resin, and a sheet forming section for forming a sheet by at least one of pressing and heating the web, a time required for manufacturing the sheet is increased, and the efficiency (operation rate) of the apparatus can be improved.
