Description

  The present invention relates to a die cutter apparatus that performs a cutting process such as punching or half-cutting on a sheet material of a sheet.

  A die cutter device such as a rotary die cutter or a platen die cutter is known as a device that performs a cutting process such as punching a single sheet into a predetermined shape or half-cutting only the seal portion of the tack seal. In the rotary die cutter, the cutting process is performed by rotating a cylindrical die, and in the platen die cutter, the flat plate die is moved up and down to perform the cutting process. Each of the die cutter devices includes a sheet storage unit in front of the introduction port for introducing the sheet. After the sheet stored in the storage unit is supplied to the introduction port by the supply mechanism, the die cutter is used. It is conveyed to the cutting position.

  Using such a die cutter device, a sheet on which images such as characters and patterns (hereinafter referred to as printed matter) are cut may be cut in accordance with the position and shape of the images. In this case, it is necessary to accurately match the position of the image of the printed matter with the position of the blade provided on the die (cut position). Therefore, in the conventional die cutter apparatus, the timing for supplying a sheet (printed material), the conveying speed, the timing for rotating or moving the die up and down, and the like can be adjusted.

  However, in the above-described die cutter device, it is necessary for the operator to once collect the printed matter printed by the printing device and set it in the storage unit of the die cutter device, which takes time and labor. Therefore, the printed product can be directly transferred from the paper discharge unit of the printing device by bringing the paper discharge unit of the printing device and the storage unit of the die cutter device close to each other or by connecting them with a connecting plate or the like. A method of installing both devices so as to be discharged is taken. However, with this method, even if a paper jam occurs at the inlet of the die cutter device, the printing device continues to discharge the printed matter, so the printed matter accumulates in the storage part of the die cutter device, and in some cases overflows and breaks. Or fouling. Therefore, when a paper jam occurs in the die cutter device, it is necessary to stop the printing device. However, since the die cutter device and the printing device are separate and independent devices, the operations of both devices are not linked. Therefore, in order to stop the printing apparatus in response to the occurrence of a paper jam in the die cutter apparatus, it is inconvenient because an operator must be waiting nearby. Such a problem also occurs when a paper jam occurs at a place other than the introduction port or when an operation abnormality other than the paper jam occurs in the die cutter device.

  On the other hand, as described in Patent Document 1, for example, an apparatus in which a printing press and a die cutter are integrated is provided. In such an apparatus, normally, when an operation abnormality such as a paper jam occurs, the entire apparatus is automatically stopped, and there is no need for an operator to wait nearby.

JP 2007-276395 A

  An apparatus in which a printing machine and a die cutter are integrated is convenient for cutting a printed material, but cannot cut a sheet that has not been printed (non-printed material). Therefore, when cutting a non-printed material, it is necessary to prepare a die cutter device separately from the above device. Moreover, even when one of the printing press and the die cutter breaks down or when it is desired to improve the function or performance of one, it is not easy to replace only one with another.

  The problem to be solved by the present invention is that when a printed matter printed by a printing apparatus is cut by a die cutter apparatus separate from the printing apparatus, an abnormal operation such as a paper jam occurs in the die cutter apparatus. However, it is to suppress the printed matter that is damaged or soiled.

In order to solve the above problems, the present invention is a die cutter device that performs a predetermined cutting process with a die cutter on a sheet material of a single wafer.
a) a storage portion for storing sheet material, having a bottom surface that can move up and down;
b) a height sensor for detecting the height of the uppermost surface of the sheet material stored in the storage unit;
c) an elevating mechanism for vertically moving the bottom surface of the storage unit;
d) a supply mechanism that supplies the die cutter with a sheet material that is located at the uppermost part of the sheet material stored in the storage unit and whose upper surface is positioned at a predetermined height;
e) an abnormality detection sensor for detecting the presence or absence of an abnormal state in the die cutter;
f) a normal mode in which the elevating mechanism is controlled so that the height of the uppermost surface of the sheet material stored in the storage unit is maintained at the predetermined height, and the maximum of the sheet material stored in the storage unit. A controller that can switch between a retreat mode for controlling the lifting mechanism such that the height of the upper surface is lower than the predetermined height, and
The control unit switches from the normal mode to the retreat mode based on the fact that the abnormality detection sensor detects the occurrence of an abnormal state.

  In the present invention, when the normal mode is executed, the uppermost surface of the sheet material in the storage unit is maintained at a predetermined height. Therefore, when a plurality of sheet materials are stored together in the storage unit, or the printing apparatus In any case where the sheet material discharged one by one is stored in the storage part, the sheet material located at the uppermost part in the storage part is supplied to the die cutter by the supply mechanism. On the other hand, when the abnormal state is detected by the abnormality detection sensor, the normal mode is switched to the retreat mode, and as a result, the bottom surface of the storage unit is lowered, and the height of the uppermost surface of the sheet material stored in the storage unit is predetermined. It becomes lower than the height. Therefore, the printed matter discharged from the printing apparatus after detection of the abnormal state can be stored in the storage unit. Moreover, since the height of the uppermost surface of the sheet material in the storage unit is lower than a predetermined height, the sheet material in the storage unit is not newly supplied to the die cutter by the supply mechanism. The abnormal state in the die cutter means that the sheet material is clogged in the path from the supply mechanism to the die cutter, or an abnormal operation of the die cutter (for example, an abnormal operation of the drive mechanism that rotates or moves the die up and down).

  In the above-described configuration, it is preferable to provide notification means for notifying that the abnormality detection sensor has detected the occurrence of an abnormal state. In this configuration, it is easy for an operator in the vicinity to notice the occurrence of an abnormal state, so that the abnormal state can be prevented from continuing for a long time.

  In the above configuration, it is preferable to include a receiving unit that receives the sheet material discharged from the discharge port of the printing apparatus and sends the sheet material to the storage unit, and the receiving unit discharges the sheet of the printing apparatus. It is good to provide the conveyance mechanism which conveys the sheet material received from the opening to the storage part. If the receiving unit does not have a transport mechanism, the receiving unit moves downward from the discharge port of the printing apparatus toward the storage unit, so that the sheet material is moved from the discharge port to the storage unit by its own weight. Can be made. On the other hand, if the receiving part is configured to include a transport mechanism, the printing apparatus can be used regardless of whether the discharge port of the printing apparatus is at a higher position than the storage part of the die cutter apparatus or at a lower position. The sheet material (printed matter) discharged from can be reliably moved toward the storage section. Further, since the restriction on the relationship between the height of the storage part of the die cutter device and the height of the discharge port of the printing device is reduced, the degree of freedom of the printing device combined with the die cutter device is increased.

In the above configuration, the receiving portion is
A mode detector for detecting whether the lifting mechanism is controlled in the normal mode or the retreat mode;
When the mode detection unit detects that the elevating mechanism is controlled in the normal mode, it drives the transport mechanism and detects that the elevating mechanism is controlled in the retract mode. In some cases, it is preferable to include a transport control unit that stops the transport mechanism.
In this configuration, when an abnormal state occurs in the die cutter and the lifting mechanism is controlled in the retreat mode, the transport mechanism is stopped, so that the sheet material discharged from the discharge port of the printing apparatus is collected in the storage unit. Can be prevented.

Moreover, the conveying apparatus according to the present invention made to solve the above-described problems is
A transport mechanism that receives the sheet material discharged from the discharge port of the printing apparatus and transports it to the storage section of the die cutter apparatus described above;
A mode detection unit for detecting whether the lifting mechanism of the die cutter device is controlled in a normal mode or a retreat mode;
When the mode detection unit detects that the lifting mechanism is controlled in the normal mode, the mode detection unit drives the transport mechanism and detects that the lifting mechanism is controlled in the retract mode. And a conveyance control unit that stops the conveyance mechanism when the apparatus is in the state.

  According to the die cutter device of the present invention, when a sheet material (printed material) printed by a printing device separate from the die cutter device is cut with the die cutter, an abnormal state occurs in the die cutter. Then, since the sheet material in the storage part is not supplied to the die cutter, it is possible to suppress the damage and contamination of the sheet material.

  Furthermore, according to the conveying apparatus which concerns on this invention, the sheet material (printed material) printed with the printing apparatus separate from the die cutter apparatus can be conveyed directly from this printing apparatus to the storage part of the die cutter apparatus. it can. Moreover, when an abnormal state occurs in the die cutter of the die cutter device and the supply of the sheet material in the storage unit to the die cutter is stopped, the die cutter device of the sheet material discharged from the printing device in conjunction with this is stopped. Since the conveyance to the storage part is stopped, it is possible to prevent the sheet material from overflowing from the storage part.

  Embodiments of a die cutter device according to the present invention will be described below with reference to the drawings. In the following embodiments, a rotary die cutter device having a cylindrical die cutter will be described as an example of the die cutter device, but the present invention is also applicable to a platen die cutter device.

[Example 1]
As shown in FIGS. 1 to 4, the rotary die cutter device 100 includes a rectangular box-shaped casing 101, a carry-in section 102, a transport section 103, and a cut processing section 104 provided on the top of the casing 101. , A discharge unit 105 for discharging the cut sheet material provided on the side wall of the casing 101 on the cut processing unit 104 side, and a discharge side storage unit for storing the sheet material discharged from the discharge unit 105 106.

  The carry-in unit 102 is located outside the housing 101, and a sheet material introduction port 107 is formed on the boundary surface with the conveyance unit 103. In addition, the carry-in unit 102 is provided with a storage unit 108 for storing the sheet material introduced from the introduction port 107 and a receiving unit 109 connected to the storage unit 108.

  The receiving part 109 is configured to be removable from the storage part 108. When a sheet material on which an image or the like is printed is cut by a printing apparatus 200 to be described later, the receiving unit 109 is attached to the storage unit 108. Otherwise, the receiving unit 109 is removed from the storage unit 108. Further, the vertical inclination of the receiving portion 109 with respect to the storage portion 108 can be adjusted. Accordingly, the height of the front end portion (end portion on the printing device 200 side) of the receiving portion 109 can be appropriately changed in accordance with the height of the paper discharge unit 203 of the printing device 200. A plurality of feed rollers 110 (corresponding to the transport mechanism of the present invention) are attached to the receiving portion 109. By these feed rollers 110, the printed matter discharged from the printing apparatus 200 is smoothly fed toward the storage unit 108. The storage part 108 is composed of a pair of side wall parts 108a facing in the direction orthogonal to the sheet material introduction direction and a bottom part 108b that can move up and down.

  A height sensor 120 (shown only in FIG. 5) for detecting the height position of the uppermost surface of the sheet material stored in the storage unit 108 and the sheet material stored in the storage unit 108 are disposed around the storage unit 108. A suction-type supply mechanism 130 that supplies the inlet 107 to the inlet 107, and an elevating mechanism that adjusts the height of the uppermost surface of the sheet material stored in the reservoir 108 by moving the bottom surface 108b of the reservoir 108 up and down. 140 is provided.

  The supply mechanism 130 includes an air suction type paper feed unit 131 disposed above the storage unit 108, and the upper surface of the uppermost sheet material stored in the storage unit 108 is at a predetermined height position. In this case, the sheet material is sucked and supplied to the inlet 107. The “predetermined height position” refers to a position within a range from 10 mm below to 20 mm below the suction port (not shown) of the paper feeding unit 131. The height sensor 120 is composed of an optical distance measuring sensor, for example, and is disposed in the vicinity of the paper feeding unit 131. Further, a clogging sensor (jam sensor) 150 (shown only in FIG. 5) for detecting the clogging condition of the sheet material at the introduction port 107 is installed in the vicinity of the introduction port 107. The clogging sensor 150 is composed of an optical sensor such as a photo interrupter that detects a sheet material passing through the inlet 107, for example. The clogging sensor 150 corresponds to the abnormality detection sensor of the present invention.

  The cut processing unit 104 includes a die cylinder 41 and a blade (not shown) mounted on the surface thereof, and a motor 42 that rotates the die cylinder 41. Further, the transport unit 103 includes a belt conveyor 31 that transports the sheet material introduced from the introduction port 107 to the cut processing unit 104.

  The printing apparatus 200 introduces a printing paper (sheet material) provided in one of a rectangular box-shaped housing 201 in which a printing mechanism is accommodated and a side wall portion facing the housing 201 into the housing 201. And a paper discharge unit 203 for discharging printed printing paper (printed material (corresponding to the sheet material of the present invention)) provided on the other side. A storage unit (not shown) for receiving printed matter discharged from the paper discharge unit 203 is attached to the lower side wall portion of the paper discharge unit 203, and the printed material is transferred from the printing device 200 to the rotary die cutter device 100. In the case of direct supply, the reservoir is removed.

  The printing apparatus 200 may be any type of printing apparatus such as an inkjet printer or a laser printer, and may be of any size. However, the distal end portion (the end portion on the printing device 200 side) of the receiving portion 109 is the base end portion so that the printed matter discharged from the printing device 200 is supplied to the storage portion 108 through the receiving portion 109 of the rotary die cutter device 100. Since it is necessary to be at the same height as the (end part on the storage unit 108 side) or higher than the base end part, when using a printing device in which the paper discharge unit 203 is low or a small printing device As shown in FIG. 1, the printing apparatus 200 is placed on a table 300.

  FIG. 5 is a block diagram illustrating a schematic configuration of a control system of the rotary die cutter apparatus 100. The rotary die cutter device 100 includes a control unit 111, a display unit 112, an operation unit 113, and a buzzer 114. In addition, a height sensor 120 and a clogging sensor 150 are connected to the control unit 111, and detection signals from these sensors are input. Furthermore, the control unit 111 is connected to the supply mechanism 130, the lifting mechanism 140, and the motor 42 of the cut processing unit 104. The control unit 111 controls the supply mechanism 130, the lifting mechanism 140, the cut processing unit 104, the buzzer 114, and the like based on conditions set by the operator through the operation unit 113 and detection signals from the height sensor 120 and the clogging sensor 150.

  Next, an operation when the rotary die cutter device 100 performs a cutting process while discharging the printed matter directly from the printing device 200 to the storage unit 108 of the rotary die cutter device 100 will be described. In the following description, printing paper set in the printing apparatus 200 and printed printing paper (printed material) discharged from the printing apparatus 200 are collectively referred to as “sheet material”.

  First, the receiving portion 109 is attached to the storage portion 108 of the rotary die cutter device 100, and the inclination of the receiving portion 109 is adjusted so that the front end of the receiving portion 109 is located slightly below the paper discharge portion 203 of the printing apparatus 200. . In this state, the sheet material is set in the paper feeding unit of the printing apparatus 200, and driving of the rotary die cutter apparatus 100 and the printing apparatus 200 is started.

  In the initial state, the bottom surface portion 108b of the storage portion 108 of the rotary die cutter apparatus 100 is located at the lowest position, and the lift mechanism 140 moves the bottom surface portion 108b upward as driving starts to increase the height of the upper surface of the bottom surface portion 108b. To a predetermined height. In this state, when the sheet material on which an image or the like is printed by the printing apparatus 200 is discharged from the paper discharge unit 203, the sheet material is conveyed along the receiving unit 109 to the storage unit 108. In this embodiment, since the feed roller 110 is attached to the receiving portion 109, the sheet material is smoothly conveyed from the paper discharge portion 203 to the storage portion.

  When the sheet material is stored in the storage unit 108, the supply mechanism 130 sucks the sheet material and sends it out toward the inlet 107. Then, the sheet material introduced into the housing 101 from the introduction port 107 is transported to the cutting position of the cut processing unit 104 by the transport unit 103 and subjected to a predetermined cutting process. The height sensor 120 outputs a detection signal corresponding to the height position of the uppermost surface of the sheet material in the storage unit 108 to the control unit 111. Based on this detection signal, the control unit 111 drives the elevating mechanism 140 so that the height of the uppermost surface of the sheet material in the storage unit 108 becomes a predetermined height (normal mode). Specifically, when the number of sheet materials in the storage unit 108 increases and the height position of the uppermost surface of the sheet material in the storage unit 108 exceeds a predetermined height, the lifting mechanism 140 moves the bottom surface of the storage unit 108. 108b is lowered, the number of sheet materials in the storage unit 108 decreases, and when the height position of the uppermost surface of the sheet material in the storage unit 108 falls below a predetermined height, the elevating mechanism 140 moves the bottom surface of the storage unit 108. 108b is raised. The supply mechanism 130 is adjusted so that the suction force of the supply unit sucks one sheet material whose upper surface is located at a predetermined height. Therefore, when the uppermost surface of the sheet material falls below a predetermined height, the supply mechanism 130 does not suck the sheet material.

When the clogging sensor 150 detects that the sheet material has passed through the introduction port 107, the clogging sensor 150 outputs a detection signal to the control unit 111. When the detection signal from the clogging sensor 150 is input, the control unit 111 controls the lifting mechanism 140 in the normal mode.
On the other hand, when the sheet material is clogged in the introduction port 107 for some reason and the sheet material does not pass through the introduction port 107, the detection signal is not output from the clogging sensor 150. If the sheet material does not pass through the inlet 107 even after a predetermined time (threshold time) elapses and the detection signal is not output from the clogging sensor 150 exceeds the threshold time, the control unit 111 enters the inlet 107. It is determined that the sheet material is jammed, and 111 drives the lifting mechanism 140 to move the bottom surface portion 108b of the storage portion 108 downward (retraction mode). Thereby, the height of the uppermost surface of the sheet material in the storage unit 108 becomes lower than a predetermined height. In the present embodiment, the bottom surface part 108b of the storage part 108 is moved to the lowest part. At the same time, the control unit 111 sounds the buzzer 114.

  When the height of the sheet material in the storage unit 108 becomes low, the supply mechanism 130 cannot suck the sheet material. Therefore, even if the sheet material discharged from the printing apparatus 200 is stored in the storage unit 108, a new sheet material is introduced. It is not introduced into the housing 101 from the port 107. Further, since the bottom surface part 108b of the storage unit 108 is located at the lowermost part, even if the sheet material continues to be discharged from the printing apparatus 200, the sheet material does not immediately overflow from the storage unit 108. Further, since the buzzer 114 can make the worker in the vicinity of the apparatus aware that the sheet material is jammed, it can be avoided that the sheet material is jammed for a long time.

[Example 2]
Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the joint conveyor 400 is used to supply the sheet material (printed matter) discharged from the printing apparatus 200A to the rotary die cutter apparatus 100A. The joint conveyor 400 corresponds to the receiving part or the conveying device of the present invention. In the following description, the same parts as those of the rotary die cutter apparatus 100 and the printing apparatus 200 according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The joint conveyor 400 is disposed between the rotary die cutter device 100A and the printing device 200A. The joint conveyor 400 is an apparatus independent of the rotary die cutter apparatus 100 </ b> A and the printing apparatus 200 </ b> A, and includes a gantry 401 with wheels and a transport mechanism 410 attached on the gantry 401. The transport mechanism 410 includes a transport path 411 composed of a plurality of conveyor belts 411a arranged side by side, a motor 412 that rotationally drives the conveyor belts 411a, a plurality of feed rollers 413 disposed on the transport path 411, It has a guide part 414 provided on one of both sides of the conveyance path 411 and a conveyor sensor 415 provided at one end of the conveyance path 411 (the end on the rotary die cutter device 100A side in FIG. 5). ing.

  The joint conveyor 400 can change the posture of the conveyance path 411 (the height position of the upper surface of the conveyance path 411 and the inclination angle of the upper surface (inclination angle in the vertical direction)). With this configuration, the conveyance path depends on the height of the bottom surface portion 108b of the storage section 108 of the rotary die cutter apparatus 100A (the height when no sheet material is stored) and the height of the paper discharge section 203 of the printing apparatus 200A. 411 can be adjusted as appropriate.

  The guide part 414 of the joint conveyor 400 is for aligning the direction of the sheet material conveyed by the conveyor belt 411a of the conveyance path 411, and from the end of the conveyance path 411 on the printing apparatus 200A side to the rotary die cutter apparatus 100A side. It is configured to extend to a place slightly beyond the end of the sheet and to be inclined by about 3 to 5 ° in the horizontal direction with respect to the transport direction of the transport path 411.

  The conveyor sensor 415 is for detecting the presence of an object that faces one end of the conveyance path 411, and includes an appropriate objective sensor (proximity sensor) such as an optical type, an ultrasonic type, or a magnetic type. When an object is present at a position facing one end of the conveyance path 411, the conveyor sensor 415 outputs an electrical signal to the conveyance control unit 420, and the conveyance control unit 420 drives the motor 412 based thereon. On the other hand, when there is no object facing one end of the conveyance path 411 and an electric signal from the conveyor sensor 415 is not input to the conveyance control unit 420, the conveyance control unit 420 stops the motor 412. The conveyor sensor 415 corresponds to the mode detection unit of the present invention.

  In this embodiment, the operation when the sheet material cut by the rotary die cutter apparatus 100A is cut while the printed sheet material is supplied directly from the printing apparatus 200A to the storage unit 108 of the rotary die cutter apparatus 100A will be described. To do.

  First, the rotary die cutter device 100A and the printing device 200A are arranged at a predetermined interval so that the storage unit 108 of the rotary die cutter device 100A and the paper discharge unit 203 of the printing device 200A face each other. At this time, the conveyance direction of the rotary die cutter device 100A and the printing device 200A is set to be the same as the paper discharge direction from the paper discharge unit 203 of the printing device 200A. Then, the joint conveyor 400 is disposed between the rotary die cutter device 100A and the printing device 200A. At this time, one end of the conveyance path 411 of the joint conveyor 400 is close to the bottom surface part 108b of the storage unit 108 of the rotary die cutter apparatus 100A, and the other end is close to the paper discharge part 203 of the printing apparatus 200A. And the orientation of the joint conveyor 400 is adjusted so that the guide portion 414 is parallel to the conveying direction of the rotary die cutter device 100A. Since the guide portion 414 is inclined by about 3 to 5 degrees in the horizontal direction with respect to the conveyance direction of the conveyance path 411, when the joint conveyor 400 is arranged as described above, the conveyance direction of the conveyance path 411 is the rotary die cutter. It is inclined in the horizontal direction by about 3 to 5 degrees with respect to the transport direction of the apparatus 100A and the discharge direction from the discharge unit 203 of the printing apparatus 200A.

  Next, the sheet material is set in the paper feeding unit of the printing apparatus 200A, and driving of the rotary die cutter apparatus 100A, the printing apparatus 200A, and the joint conveyor 400 is started. At the start of driving of the rotary die cutter device 100 </ b> A, the bottom surface portion 108 b of the storage portion 108 is positioned at substantially the same height as one end portion of the transport path 411 of the joint conveyor 400 and is close to the conveyor sensor 415. For this reason, an electrical signal from the conveyor sensor 415 is input to the conveyance control unit 420, and the conveyance control unit 420 drives the motor 412. Accordingly, when the sheet material S on which an image or the like is printed by the printing apparatus 200A is discharged from the paper discharge unit 203, the sheet material S is discharged onto the conveyance path 411 of the joint conveyor 400 and conveyed by the conveyor belt 411a. The At this time, since the conveyance direction of the conveyance path 411 is inclined with respect to the discharge direction from the printing apparatus 200A, the sheet material S is slightly inclined in the horizontal direction with the conveyor belt 411a together with the conveyor belt 411a. After moving and the front corner hits the guide part 414, it goes along the guide part 414 to the storage part 108 of the rotary die cutter apparatus 100A. For this reason, the sheet material S sequentially discharged from the printing apparatus 200 </ b> A reaches the storage unit 108 in a state where the lateral positions (positions in the direction orthogonal to the transport direction) are aligned.

  When the sheet material is stored in the storage unit 108, the supply mechanism 130 sucks the sheet material located at the uppermost part and delivers it toward the inlet 107. Then, the sheet material introduced into the housing 101 from the introduction port 107 is transported to the cutting position of the cut processing unit 104 by the transport unit 103 and subjected to a predetermined cutting process. The height sensor 120 outputs a detection signal corresponding to the height position of the uppermost surface of the sheet material in the storage unit 108 to the control unit 111. Based on this detection signal, the control unit 111 drives the elevating mechanism 140 so that the height of the uppermost surface of the sheet material in the storage unit 108 becomes a predetermined height (normal mode). While the uppermost surface of the sheet material S is at a predetermined height position, the bottom surface portion 108b or the sheet material S is close to the conveyor sensor 415, and an electric signal is input from the conveyor sensor 415 to the conveyance control unit 420. Therefore, the motor 412 continues to drive.

  On the other hand, if the sheet material S is clogged in the introduction port 107 for some reason and the sheet material S does not pass through the introduction port 107 even after a predetermined time (threshold time) has elapsed, the control unit 111 detects the clogging sensor 150. It is determined from the signal that the sheet material is clogged in the inlet 107. Then, the control part 111 drives the raising / lowering mechanism 140, moves the bottom face part 108b of the storage part 108 below, and makes height of the uppermost surface of the sheet material S in the storage part 108 lower than predetermined | prescribed height. In this embodiment, the bottom surface part 108b of the storage part 108 is moved to the lowest part. Then, the object close to the conveyor sensor 415 disappears, and the output of the electric signal from the conveyor sensor 415 to the conveyance control unit 420 is stopped, so that the conveyance control unit 420 stops the motor 412. As a result, the sheet material S discharged from the printing apparatus 200 </ b> A is accumulated on the conveyance path 411 of the joint conveyor 400 and is not supplied to the storage unit 108.

  At the same time, the control unit 111 sounds the buzzer 114 to notify an operator around the apparatus that the sheet material is jammed. For this reason, it can be avoided that the sheet material is continuously jammed for a long time.

In addition, this invention is not limited to the said embodiment, A various change is possible.
For example, a lamp that is turned on when an abnormal state is detected by the abnormality detection sensor may be provided, or a speaker that emits a sound for notifying the occurrence of the abnormal state may be provided.
Although the receiving portion is provided in the above embodiment, the receiving portion may not be provided. Further, it may be a telescopic receiving part.
When there is a place where the sheet material is clogged other than the introduction port 107, a clogging sensor may be provided at that place. Further, a sensor for detecting an operation abnormality other than the jam of the sheet material may be provided, and the lifting mechanism may be driven based on the detection signal of this sensor.
