Description

  The present invention provides a sheet processing machine for performing predetermined processing such as cutting and printing on a sheet such as paper or a compact disc so that only a sheet having a predetermined thickness is supplied to the processing unit. The present invention relates to a conveyance control device that controls a conveyance state.

In a sheet processing machine that performs predetermined processing on sheets, such as a cutting machine such as a shredder or card cutting machine, or a printing device such as a copying machine or a printer, a specified number of sheets are transferred to a processing unit that performs cutting or printing. It is desired to be supplied. In addition, it is necessary to prevent the unsuitable processing from being supplied to the processing unit.
For example, in a cutting machine such as a shredder or a card cutting machine, Patent Document 1 and Patent Document are known as techniques for preventing a finger from being accidentally inserted into a sheet insertion slot or a tie or the like being caught in the insertion slot. There are those shown in 2.

Patent Document 1 discloses a technique of providing a proximity sensor that detects the presence of a person or an animal in the vicinity of an input port in order to detect an undesirable object such as a human finger entering the input port of a shredder. ing. Patent Document 2 discloses a technique in which a paper guide having a recessed portion at the top is installed around a paper slot of a cutting machine in order to prevent a tie or the like from being caught by a cutter.
In addition, as a method of supplying sheets one by one in the paper sheet conveying apparatus, there are methods shown in Patent Document 3 and Patent Document 4.

In Patent Document 3, when a sheet is not supplied to the conveyance path due to adsorption or catching between sheets, in Patent Document 3, the sheet hopper table is lowered and the sheet is guided by an inclined supply guide that continues from the hopper table to the conveyance path. Disclosed is a technique for shifting the contact surface between the conveying roller and the use by shifting and moving up, and resuming the supply by obtaining a higher frictional driving force. Patent Document 4 similarly discloses a sheet hopper table. The hopper table is moved again by removing the factor that the sheet was not fed by removing the factor that caused the sheet to fall by shifting the sheet by shifting the sheet by the weight of the sheet and the inclination of the supply guide. A technique for restarting the supply by raising the value is disclosed.

  However, the technique disclosed in Patent Document 1 requires a proximity sensor that can distinguish and detect an undesirable object such as a person or an animal and an object to be cut, and depending on the position of the sensor, There is a risk that it will also react to the operator's hand when inserting the object to be cut, which may hinder the cutting work.

  In particular, in a shredder configured to automatically rotate the cutting blade at the same time as the object to be cut is inserted, a separate sensor is required to detect the insertion of the object to be cut. In addition to being complicated, it is difficult to adjust the mounting position. For this reason, since manufacturing cost increases and a product price becomes high, it is difficult to spread as a shredder for home use.

The technique disclosed in Patent Document 2 may reduce the situation where the tie is unintentionally cut, but it is effective when a finger or the like is consciously inserted into the paper insertion slot due to a child's mischief or the like. There is no.
The techniques of Patent Document 3 and Patent Document 4 are preferable as a technique for resuming the conveyance when the supply of the sheet to the conveyance path is stopped, but when a sheet thicker than a predetermined thickness is conveyed, Cannot be moved in the direction opposite to the conveying direction, and it is impossible to prevent an undesirable object from being supplied to the processing unit.

  Therefore, an object of the present invention is to provide a conveyance control device that can effectively prevent an object having a thickness greater than a predetermined thickness from being supplied to a processing unit in a sheet processing machine, while having a simple structure. To do.

  In order to solve the above problems, a conveyance control device according to the present invention is a conveyance control device that controls a conveyance state of a sheet in a sheet processing machine that performs predetermined processing on a sheet material, and a conveyance surface on which a sheet is conveyed And a first rotating body that conveys the sheet in the processing direction, a second rotating body that is disposed to face the conveying surface at a predetermined interval, and the first rotating body. And a gear that rotates the second rotating body in a direction opposite to the first rotating body in conjunction with the first rotating body, and a transported object having a thickness exceeding the predetermined interval is transported by the second rotating body. It is characterized by being configured to return in the opposite direction.

  In this case, the gear rotates in the second direction in conjunction with the first gear rotating in the same direction as the first rotating body by the rotational force of the first rotating body. And a second gear that rotates the body in a direction opposite to the first rotating body, and the second rotating body is displaced in a direction away from the transport surface to thereby move the second gear. The first gear may be displaced in a direction to engage with the first gear, and the second gear may be interlocked with the first gear.

In addition, two sets of the first rotating body, the second rotating body, the first gear, and the second gear are provided, and on the transport surface disposed to face each other at a predetermined interval, You may make it each arrange | position a 2nd rotary body.
In addition, the first gear may be rotated through a winding transmission device spanned between the first rotating body and a rotation shaft of the first rotating body.

The first rotating body may be a rotary blade 5 that cuts while winding a sheet.
In this case, the interval between the transport surface and the second rotating body may be set to a width narrower than the thickness of the infant's finger.

  The conveyance control device according to claim 1 includes a first rotating body that conveys a sheet in a processing direction, and a second rotation that is opposed to the conveyance surface on which the sheet is conveyed at a predetermined interval. And a gear that rotates the second rotating body in the reverse direction in conjunction with the first rotating body so as to return the conveyed product having a thickness exceeding a predetermined interval in the direction opposite to the conveying direction. Since it comprised, the conveyed product which contacted the surrounding surface of the 2nd rotary body can be efficiently returned to a reverse direction using the rotational force of a 1st rotary body.

This makes it possible to prevent the conveyed product from being processed when a conveyed product thicker than the width between the conveying surface and the second rotating body is conveyed.
For this reason, for example, in a cutting machine that performs a cutting process on a sheet, by setting the width between the conveyance surface and the second rotating body to a length corresponding to the cutting ability of the cutting blade, It is possible to prevent the situation that the sheet is bitten and the supply of things that should not be cut such as fingers and ties to the cutting blade.

Further, for example, in a printing apparatus that performs a printing process or the like on a sheet, by setting the distance between the conveyance surface and the second rotating body in accordance with the thickness of the sheet material, the sheet is fed to the printing unit. Each sheet can be fed one by one, and when a sheet with an unspecified thickness is loaded into a paper feeder, the sheet is returned to the direction opposite to the conveying direction, so that the printing process can be performed on the sheet. It can be prevented from being applied.
Here, the conveyance surface is a passage surface on the side on which the sheet is placed and conveyed when conveyed in the horizontal direction, and constitutes a passage when conveyed in the vertical direction. It shall mean any one of the wall surfaces.

  In the conveyance control device according to claim 2, a first gear that rotates in the same direction as the rotation direction of the first rotating body, and a second gear that rotates in the opposite direction in conjunction with the first gear; When the second rotating body is displaced in a direction away from the conveyance surface, the second gear is displaced in a direction to engage with the first gear, and the second gear is interlocked with the first gear. As a result, when an object wider than the distance between the conveyance surface and the second rotating body is conveyed, the second gear is displaced in a direction away from the conveying surface. Is engaged with the first gear, the second rotating body that has been freely rotating in the initial state rotates in the direction opposite to the conveying direction, and moves the conveyed object in a direction away from the processing unit. Can do.

  Thereby, when a sheet with a specified thickness is conveyed, the second rotating body functions as a roller that rotates in the conveying direction according to the conveyed object, and when a sheet with a thickness greater than the specified value is conveyed, It can function as a return roller that rotates in the reverse direction, and the conveyance state can be controlled more effectively.

According to a third aspect of the present invention, there is provided a conveyance control device in which two sets of a first rotating body, a second rotating body, a first gear, and a second gear are provided, and the conveying surfaces are arranged to face each other at a predetermined interval. Since the second rotating bodies are arranged on the top, the conveyance of the sheet can be controlled even when the sheet is conveyed while contacting any surface.
When a sheet having a thickness within a predetermined range is conveyed even when the sheet being conveyed can come into contact with any surface, such as when a vertical path is formed by two vertical surfaces. A function as a roller and a function as a return roller in the case where a sheet having a thickness exceeding a predetermined range and having a thickness not less than a predetermined range is conveyed.

In the conveyance control device according to the fourth aspect of the invention, the first gear is rotated via the winding transmission device that is stretched between the rotation shaft of the first rotating body. Even when the first rotating body is provided at a position away from the rotating body, the sheet conveyance can be controlled effectively.
In the conveyance control device according to the fifth aspect, since the first rotary body is a rotary blade that cuts while winding a sheet, in a cutting machine such as a shredder or a card cutting machine, the one that should not be cut is a rotary blade. It can be prevented from being transported to.
As a result, it is possible to effectively prevent the operator's fingers and ties from being cut, and to prevent anything exceeding the cutting ability of the rotary blade from being supplied to the cutting blade. Can do.

  In the conveyance control device according to the sixth aspect, the distance between the conveyance surface and the second rotating body is set to a width narrower than the thickness of the infant's finger. Can be moved in the direction opposite to the direction of the rotary blade by the second rotating body, it is possible to reduce the risk of a major accident such as finger cutting.

  A preferred embodiment of the present invention will be described with reference to the accompanying drawings. In addition, embodiment is not limited to the following forms, Other aspects are also possible if the subject of this invention can be solved.

FIG. 1 is a perspective view showing a transport control device 1 according to a first embodiment of the present invention. This conveyance control device 1 is used for controlling the conveyance state when conveying a sheet material from the inlet 3 of the shredder 2 shown in FIG. 2 toward the rotary blade 5 inside the housing 4. .
First, the structure of the shredder 2 as a sheet processing machine to which the conveyance control apparatus 1 according to the present invention is applied will be described.

The shredder 2 is for cutting a sheet-like object to be cut such as paper or a compact disk, and the object to be cut fed from the slot 3 is cut by a rotary blade 5 provided inside the housing 4. And it discharges | emits to the waste storage box 6 provided in the downward direction of the rotary blade 5 (refer FIG. 1).
A door 8 is rotatably attached to the front surface of the housing 4 of the shredder 2. If this door 8 is opened, the waste collection box 6 is accommodated so that it can be pulled out forward.

On the upper surface of the housing 4, a loading port 3 for loading a sheet is provided.
As shown in FIG. 1, a pair of rotary blades 5 for performing sheet cutting processing is disposed below the insertion port 3. This rotary blade 5 is provided with a number of sharp cutting blades on the peripheral surface of the cylindrical body, and the two cylindrical bodies are arranged in parallel horizontally and are provided on the wall surface of the housing 4 at both ends. The frame is rotatably supported.

A sensor (not shown) is attached above the rotary blade 5, and when the sensor detects the passage of the object to be cut, a drive motor (not shown) is activated, and the cylindrical rotary blade 5 is rotated. The object to be cut that passes between the rotary blades 5 is finely cut.
The drive motor for rotating the rotary blade 5 is connected to a power supply circuit that is closed by turning on a power switch (not shown) provided in the housing 4. Further, a series of devices for driving the rotary blade 5 includes a shutter (not shown) that shields between the rotary blade 5 and the waste collection box when the door 8 of the housing 4 is opened and the waste collection box 6 is pulled out. , You can not touch the hand directly.

Next, the conveyance control device 1 applied to the shredder 2 will be described in detail. A passage for an object to be cut is formed from the inlet 3 of the shredder 2 toward the rotary blade 5.
This passage is formed by two wall surface members 10 and 11 continuous from the upper surface of the housing. Of these, the rear wall member 10 on the back side is made of a plate member made of metal or synthetic resin, and the passage is widened. It can be elastically deformed in the direction.

  As shown in FIG. 2, a slit-shaped opening 12 extending in a direction orthogonal to the transport direction is provided in the intermediate portion of the rear wall member 10. A mounting frame 13 is formed on both sides of the rear wall member 10 where the opening 12 is provided. The mounting frame 13 faces away from the passage. A cylindrical rotating roller 20 is provided on the mounting frame 13. It is supported. Specifically, the rotating roller 20 is slightly protruded from the opening 12 of the rear wall member 10 in the direction of the passage, and a part of the peripheral surface thereof is exposed from the opening 12. 11 is arranged opposite to the main body 11 at a predetermined interval.

The rotating roller 20 can rotate in both forward and reverse directions, and a second gear 31 (described later) is attached to the rotating shaft 21.
On the other hand, the front wall member 11 disposed on the front side functions as a conveyance surface on which a sheet is conveyed, and is smoothly curved toward the rotary blade 5 inside the housing 4.
As shown in FIG. 3, the distance M between the front wall member 11 and the rotating roller 20 is set to a width (10 mm or less) narrower than the thickness of the infant's finger and according to the cutting ability of the rotary blade 5. Has been. In addition, the thickness of an infant's finger shall mean the length N shown in FIG.

A pair of rotary blades 5 is disposed below the wall surface members 10 and 11. The rotary blade 5 performs a cutting process while winding a sheet, and has both a function as a processing unit that performs the cutting process and a function as a conveyance unit that conveys the sheet in the processing direction. .
Among the rotary blades 5, the first rotary blade 50 disposed on the side facing the front wall member (that is, the rotary blade 50 positioned on the extension of the rear wall member 10) is a surface on the back side of the seat. The sheet is supported by the contact resistance and functions as a first rotating body that conveys the sheet while it is rolled up.

A pulley 51 is fixed to the end portion of the first rotary blade 50, and the rotational force of the first rotary blade 50 is caused in the vicinity of the rotary roller 20 by the transmission belt 52 wound around the pulley 51. It is transmitted to the first gear 30 provided in the.
The first gear 30 is rotated in the same direction as the first rotary blade 50 by the rotational force of the first rotary blade 50. The first gear 30 is an external gear, and is a second gear mounted on the rotary shaft of the rotary roller 20 on the same plane as the first gear at a position slightly away from the external gear. The gear 31 is arranged.

The second gear 31 is a small gear with external teeth, and is engaged with the external teeth of the first gear 30 so that the first gear 31 is rotated at a rotational speed faster than the rotation of the first rotary blade 50. The rotating blade 50 rotates in the opposite direction.
As a result, as shown in FIG. 3B, when the rotating roller 20 and the rear wall member 10 are elastically deformed in the direction A away from the front wall member 11, the second gear 31 becomes the first gear 30. The rotating roller 20 is rotated in the direction opposite to the first rotary blade 50 by the second gear 31 that is displaced in the direction of meshing with the first gear 30 and rotates in the direction opposite to the first gear 30.

A state in which the conveyance of the sheet is controlled in the shredder 2 having the above configuration will be described with reference to FIG.
When performing the cutting operation, the sheet is input into the input port 3. At this time, the sheet is smoothly slid down on the curved front wall member 11 by being slid from the front side of the housing 4 toward the insertion port 3, and passes through the passage to the rotary blade 5. And so on. At this time, the passage of the sheet is detected by the sensor, and the rotary blade 5 is driven. When the sheet passes between the rotating blades 5 in the rotating state, the sheet is finely cut while being wound around the rotating blade 5. When the sheet passes through the passage, it contacts the rotating roller 20 of the rear wall member 10, whereby the rotating roller 20 rotates in the sheet conveying direction. When the subsequent sheet comes into contact with the rotating roller 20 in the rotating state, the sheet is sequentially and smoothly conveyed to the rotary blade 5.

If a thing thicker than the gap M between the front wall member 11 and the rotary roller 20 is thrown into the slot 3, as shown in FIG. 3B, the rotary roller 20 and the rear wall member 10 However, the second gear 31 is engaged with the first gear 30 with the displacement in the direction A away from the front wall member 11.
As a result, the rotational force of the first rotary blade 50 rotating in the direction in which the seat is pulled into the housing 4 is transmitted via the transmission belt 52 and the first gear 51. The second gear 31 is rotated in the reverse direction, and accordingly, the rotary roller 20 rotates in the direction opposite to the first rotary blade 50 (that is, the direction in which the sheet is pushed out of the housing 4).

  By setting the interval M between the front wall member 11 and the rotary roller 20 to a width corresponding to the cutting ability of the rotary blade 5, when the number of sheets exceeds the number of sheets that can be cut, the rotary roller 20 or the rear roller 20 Since the wall member 10 is displaced in the direction away from the front wall member 11 and the second gear 31 is engaged with the first gear 30, the sheet in contact with the rotating roller 20 is returned in the direction opposite to the conveying direction. It is. As a result, the sheet can be fed into the rotary blade 5 by an appropriate amount, so that it is possible to prevent a situation in which the sheet is caught in the rotary blade 5 and the rotary blade 5 stops. Further, it is possible to prevent the rotary blade 5 from being damaged by the sheet being bitten by the rotary blade 5.

Further, even when the finger is erroneously inserted into the insertion port 3, the possibility that the finger reaches the rotary blade 5 can be reduced because the rotary roller 20 returns it to the side opposite to the conveyance direction.
The conveyance control apparatus 1 according to the present embodiment is applied to a shredder that performs shredding processing on a sheet, but a card cutting machine that cuts a sheet into a predetermined size, and a printing apparatus that prints sheets one by one. The present invention may be applied to a sheet feeding feeder.

When applied to a paper feeder, the feed roller disposed on the side facing the transport surface on which the sheet is placed and transported functions as the first rotating body in the present invention. Since the rotational force of the feed roller that feeds to the printing unit while supporting the sheet by contact resistance with the sheet surface can be efficiently used for the rotational force of the rotary roller 20 that functions as a return roller, Thus, a sheet conveyance control mechanism can be configured.
As in the modification shown in FIG. 5, two sets of the first rotary blade 50, the feed roller 20 ′, the first gear 30 ′, and the second gear 31 ′ are provided with a predetermined interval. Two transport rollers 20 ′ and 20 ′ may be disposed on the transport surfaces 10 and 11 disposed to face each other.

  In this way, even if a sheet is loaded from either the front side or the back side, when an appropriate amount of sheet is loaded, as shown in FIG. As shown in FIG. 5 (b), when the sheet is smoothly transported to the rotary blade 5 and inserted beyond the prescribed number, or when something that should not be cut, such as a finger, is inserted, It is possible to prevent the roller 20 'from being conveyed to the rotary blade 5 by the returning action.

  In the present embodiment, the first gear 30 is rotated via the transmission belt 52 that is stretched between the first rotating blade 50 and the rotating shaft of the first rotating blade 50. If the radius of the first gear 30 ′ attached to the rotating shaft is matched with the distance to the rotating roller 20, it is not necessary to use a winding transmission device such as a transmission belt. Alternatively, a plurality of stages of gears may be provided between the first rotary blade 50 and the first gear 30, and the rotational force of the first rotary blade 50 may be transmitted via the gear.

  Further, although the interval M between the front wall member 11 and the rotating roller 20 is set to a width narrower than the thickness of the infant's finger in consideration of safety, it is not necessarily required to be smaller than the thickness of the infant's finger. .

FIG. 6 is a cross-sectional view showing a transport control apparatus 1 ′ according to the second embodiment of the present invention. This conveyance control device 1 ′ is applied to the inlet portion of the sheet cutting machine having the inlet 3 on the side surface of the housing 4.
The conveyance control device 1 ′ can effectively control the conveyance of the sheet when the sheet is placed on the conveyance surface and conveyed, for example, in the horizontal direction.

On the extension of the conveyance surface 15, the rotary blades 5 that perform sheet cutting processing are arranged side by side. The 1st rotary blade 50 arrange | positioned upward contacts the upper surface of a sheet | seat, and conveys it, supporting the sheet | seat by the contact resistance. The sheet is cut in cooperation with the lower rotary blade.
The first rotary blade 50 also functions as an external gear provided on the peripheral surface of the cylindrical body, and a gear 40 is provided so as to mesh with the external teeth. As shown in FIG. 7, the gear 40 has a central portion that is recessed toward the inside, and internal teeth are formed in the recess. A small gear 41 attached to the rotation shaft 21 of the rotating roller 20 is meshed with the inner teeth. The small gear 41 rotates in the same direction as the gear 40 by the rotation of the gear 40.

The rotating roller 20 is disposed on the upper side of the conveying surface 15 with a predetermined interval M therebetween, and is rotated by the small gear 41 that rotates in the same direction as the gear 40 by the rotation of the gear 40. Is rotated in the opposite direction.
As a result, the rotating roller 20 can be rotated in the direction opposite to the conveying direction by directly using the rotational force of the upper rotary blade 50.
Thereby, when a thing thicker than the predetermined interval M is conveyed, the conveyed product can be returned in the reverse direction.

  In this embodiment, the gear 40 has an external tooth that meshes with the upper rotary blade 50 and rotates, and an internal tooth that rotates the small gear in the same direction. The rotating small gear 41 rotates the rotating roller 20 in the direction opposite to the upper rotating blade 50. As shown in FIG. 8, a gear 45 is attached to the rotating shaft of the rotating roller 20, The outer teeth of the gear 45 mesh with the outer teeth of the gear 46 that is pivotally attached to the rotation shaft of the first rotary blade 50, so that the rotary roller 20 is moved to the first using the rotational force of the first rotary blade 50. The rotary blade 50 may be rotated in the opposite direction.

  The present invention can be applied to any apparatus as long as it is a cutting machine that performs a cutting process on a sheet, a printing machine that performs a printing process on a sheet, or an apparatus that performs a predetermined process on a sheet material.
