As shown in FIG. 3, the printing apparatus 1 is provided with a return prevention member 7. When the plate discharging box 10 is attached to the printing apparatus 1, the return preventing member 7 protrudes inward from the front end side of the opening 20 of the plate discharging box 10 at a position where it does not interfere with the rotating compression means 6, and after compression, When the compressing means 6 returns to the front, the discharged plate S is prevented from flowing back out of the discharged plate box 10.

As shown in FIG. 1, the plate removal box 10 of the present embodiment that is detachable from the detachable portion 3 of the printing apparatus 1 is suitable for a plate removal S of a large or wide printing plate. That is, for example, a size that can cope with a printing plate having a size of A2 or more (width of 594 mm or more), or even a smaller A3 size that is discharged with the long side (420 mm) in the width direction. Is set. In this way, the discharge box 10 is a large type having a dimension in the width direction perpendicular to the discharge direction of at least 420 mm. When the stored discharge plate S is discarded or maintenance is performed, the user can use one hand operation with both hands. It can be removed from the printing apparatus 1 as shown.
As will be described in detail later, the plate removal box 10 pulled out and removed by the user with both hands from the printing apparatus 1 is folded into two in the width direction by the user's one-touch operation (see FIG. 6), and the opened connection portion The discharged plate S folded in half from the opening can be discarded.

  As shown in FIGS. 1 to 3, the plate removal box 10 has a box-shaped main body 11 in which the plate removal S is stored. The main body 11 is a hollow housing composed of a bottom plate 15, a pair of side plates 16, 17, a rear plate 18, and an upper plate 19 as a whole. The front surface of the main body 11 and the front portion of the upper plate 19 are opened as an opening 20 into which the compression means 6 of the printing apparatus 1 enters in order to compress the discharged plate S. A bottom plate 15 which is a bottom portion of the main body 11 includes a rear flat plate portion 15 b and a front curved plate portion 15 a having a shape along the locus of the compression means 6. The pair of side plates 16 and 17 are parallel to the compression direction of the compression means 6 and rise vertically from the flat plate portion 15 b of the bottom plate 15 to close the left and right side surfaces of the main body 11. The rear plate 18 faces the compression direction of the compression means 6 and is perpendicular to the side plates 16 and 17 and the bottom plate 15. In addition, the holding part 21 which becomes a clue for a user to hold | maintain is provided in the outer surface (rear surface of the main body 11) of the rear plate 18 so as to protrude.

  As described above, the main body 11 as a whole is an elongated hollow box whose longitudinal direction is the width direction orthogonal to the plate discharging direction of the printing apparatus 1, but is divided into two box portions at the center in the width direction. Yes. FIG. 6 schematically shows this state, and these two box portions are referred to as a first box portion 12 and a second box portion 13. As shown in FIG. 6, the outer side in the width direction of the first box portion 12 is the side plate 16, and the inner side is the first discharge port 12 a that is adjacent to and communicates with the second box portion 13. The outer side in the width direction of the second box part 13 is the side plate 17, and the inner side is a second discharge port 13 a that is adjacent to and communicates with the first box part 12. The upper plate 19 close to the first discharge port 12a of the first box portion 12 and the upper plate 19 close to the second discharge port 13a of the second box portion 13 are hinges 22 serving as connecting portions of the rotation center. By being connected, the 1st box part 12 and the 2nd box part 13 are connected so that each can rotate upwards. When the plate discharge box 10 is mounted on the printing apparatus 1 and stores the plate discharge S, the first discharge port 12a and the second discharge port 13a are connected to each other and closed, and are removed from the printing device 1 to remove the discharge plate S. When discarding, both the box portions 12 and 13 are folded in half by the hinge 22 so that the first discharge port 12a and the second discharge port 13a are separated from each other and the inside is opened.

  As shown in FIG. 3, the inner surface of the bottom plate 15 of the plate discharging box 10 composed of the first box portion 12 and the second box portion 13 is compressed to prevent the discharged plate S that has been sent and compressed from sticking to the inner surface. A large number of bottom ribs 23 are formed in parallel with the compression direction of the discharged plate S by the means 6. The bottom rib 23 provided on the curved plate portion 15a of the bottom plate 15 not only prevents the discharged plate S from sticking, but also the compression means 6 that rotates in the main body 11 enters and rotates. It also has a function of assisting the action of reliably pushing the discharged plate S backward and compressing it. Further, the bottom rib 23 provided on the flat plate portion 15b of the bottom plate 15 of the main body 11 is provided in parallel with the compression direction. Further, in order to prevent the discharged plate S from sticking to the inner surface of the rear plate 18, a large number of compressed portion ribs 24 are formed along a vertical direction parallel to the compression direction of the discharged plate S by the compression means 6. Yes. Further, although not shown in FIG. 3, the inner surface of the bottom plate 15 of the plate discharging box 10 including the first box portion 12 and the second box portion 13 is predetermined in a direction orthogonal to the compression direction of the plate discharging S by the compression means 6. A large number of width direction ribs are formed at intervals. Accordingly, the width-direction ribs, together with the bottom ribs 23, constitute lattice-like ribs on the inner surface of the bottom plate 15 of the plate removal box 10. In a state immediately before discarding the discharged plate S, the width direction ribs of both the box portions 12 and 13 and the discharged plate S in the both box portions 12 and 13 are in contact with each other in a continuous state along the width direction of the discharged plate S. When the first box portion 12 and the second box portion 13 are rotated around the hinge 22, the plate removal S is driven by the rotation of both the box portions 12 and 13, and the large pushing force based on the frictional force or the like from the width direction rib. Therefore, the discharged plate S is smoothly pushed out of the discharged plate box 10 and reliably discarded.

  As shown in FIGS. 1 to 3, the first box portion 12 and the second box portion 13 that constitute the main body 11 of the discharge box 10 are provided with a claw-like engagement member 25 that is an attachment / detachment mechanism with respect to the printing apparatus 1, An attachment / detachment lever 26 for operating the engagement member 25 to operate engagement / disengagement with respect to the printing apparatus 1 is provided. As described above, the first box portion 12 and the second box portion 13 are each provided with the gripping portions 21 that are held by the user when the plate discharging box 10 is attached / detached so as to protrude from the outer surface of the rear plate 18. The detachable lever 26 for operating the combined member 25 can be operated by a part of the fingers of the hand while the user holds the grip portion 21. In other words, the discharge box 10 operates each of the detachable levers 26 and 26 with a part of fingers of the hands while holding the grip portions 21 and 21 of the first box portion 12 and the second box portion 13 with one hand. Then, the engagement with the printing apparatus 1 is released, and it can be detached from the printing apparatus 1 by pulling both hands as it is.

Next, the operation in this example will be described with reference to FIG.
According to the present embodiment, as shown in FIG. 6A, the first discharge port 12a of the first box portion 12 and the second discharge port 13a of the second box portion 13 are connected to each other to be closed, The 1 box part 12 and the 2nd box part 13 are attached to the printing apparatus 1 in the state which became the one plate discharge box 10 as a whole. When the printing apparatus 1 is used, if it is necessary to discharge the plate, the discharged plate S is sent from the opening 20 into the discharged plate box 10 by the plate discharging means 4 (see FIG. 3). At the time of this plate removal, the compression means 6 of the plate release means 4 operates as necessary, so that the plate release S in the plate release box 10 can be pressed and compressed in the plate release direction, and the volume of the plate release S in the plate release direction can be increased. Can be small.

  When the discharged plate 10 is full and the discharged plate S is discarded, the discharged plate box 10 is removed from the printing apparatus 1 as follows, and the discharged plate S is discarded from the discharged plate box 10 to the discarded box. First, the user holds the holding portions 21 and 21 of the first box portion 12 and the second box portion 13 with the right hand and the left hand, respectively, and the attachment / detachment levers 26 and 26 of the box portion with a part of the fingers of each hand. Are respectively operated to release the engagement of the engagement members 25 and 25 with the printing apparatus 1, and the unloading box 10 is pulled out of the printing apparatus 1 with both hands and removed. Next, as shown in FIG. 6B, the user rotates the first box portion 12 and the second box portion 13 of the discharge box 10 held by both hands upward about the hinge 22. The first discharge port 12a and the second discharge port 13a are opened downward. Since the bottom ribs 23 and the compression ribs 24 are provided on the inner surfaces of both the box portions 12 and 13, the internal discharge plate S is firmly attached to the inner surfaces of both the box portions 12 and 13 in a wide area. Rather, due to the movement of the box portions 12 and 13 relative to each other by rotation, the discharged plate S is easily peeled off from the bottom ribs 23 and the compression portion ribs 24 of the box portions 12 and 13, and the discharge ports 12a and 12a. It falls outside 13a and is discarded. As a result of this discarding operation, the first box portion 12 and the second box portion 13 of the discharging box 10 are rotated around the hinge 22 parallel to the discharging direction so as to collide with each other. Then, the discharged plate S compressed in the discharged plate direction is further folded in two with respect to the width direction orthogonal to the discharged plate direction, with the hinge 22 as the center, and is further reduced in volume and compactly formed. That is, the projected area of the discarded plate S on the plane is sufficiently smaller than the opening area of a disposal box having a general opening width of less than 420 mm. Therefore, even a disposal box having an opening width smaller than the width of the discharged plate S can be stored without any trouble by discarding. This operation may be performed directly above a waste box (not shown) so that the dropped plate S is discarded as it is in the waste box.

2. Second Embodiment (FIGS. 4 and 5)
According to the discharge box 10 of the first embodiment, when the discharge plate S is discarded, the first box portion 12 and the second box portion 13 are rotated about the hinge 22 to discharge the discharge ports 12a of the both box portions 12 and 13 respectively. , 13a can be opened and folded to dispose the waste S in half. However, in order to more reliably discharge the discharged plate S from both the discharge ports 12a and 13a of both opened box portions 12 and 13, the discharged plate box 10 of the second embodiment further includes an extruding member for the discharged plate S.

  4 has a rod-like push-out member 30 that is provided inside the second box portion 13 and is slidable and retractable from the second discharge port 13a. The operation part 31 provided in the pushing member 30 protrudes out of the box part 13 through a groove (not shown). In FIG. 4, the pushing member 30 is provided only in the second box portion 13, but the pushing member may be provided toward the first box portion 12 or provided in both the box portions 12 and 13. May be.

  When discarding the discharged plate S, the operator removes the discharged plate box 10 from the printing apparatus 1, rotates the first box portion 12 and the second box portion 13 about the hinge 22, and folds the discharged plate box 10 in half. The first outlet 12a and the second outlet 13a are opened downward. Thereafter, the operator performs an operation of sliding the operating portion 31 to cause the push-out member 30 to protrude from the second discharge port 13a and projecting the internal discharge plate S to the outside. In this way, by allowing the extrusion member 30 to protrude from the inside of the box portion 13 to the outside, it is possible to forcibly push out the discharged plate S that was inside the box portion 13. It is possible to smoothly and reliably drop and discard the discharged plate S accompanying the rotation.

  The plate discharging box 10 shown in FIG. 5 is provided so as to rotate together with the first box portion 12 around the hinge 22, and when the plate discharging is performed by connecting the first box portion 12 and the second box portion 13, A first push-out member 32 that is located inside and moves to the outside of the second box portion 13 at the time of disposal when the first box portion 12 and the second box portion 13 are rotated is provided. The plate release box 10 is provided so as to rotate together with the second box portion 13 about the hinge 22, and the inside of the first box portion 12 is disposed when the first box portion 12 and the second box portion 13 are connected. There is a second push-out member 33 that moves to the outside of the first box portion 12 at the time of disposal when the first box portion 12 and the second box portion 13 are rotated. In addition, in FIG. 5, although both the 1st and 2nd extrusion members 32 and 33 are provided, any one may be sufficient.

  When discarding the discharged plate S, the operator removes the discharged plate box 10 from the printing apparatus 1, rotates the first box portion 12 and the second box portion 13 about the hinge 22, and folds the discharged plate box 10 in half. The first outlet 12a and the second outlet 13a are opened downward. By this operation, the first pusher member 32 rotates around the hinge 22 in conjunction with the rotating first box portion 12 and moves from the inside of the second box portion 13 to the outside. Further, the second pusher member 33 rotates around the hinge 22 in conjunction with the rotating second box portion 13 and moves from the inside of the first box portion 12 to the outside. Since the two pushing members 32 and 33 are moved from the inside of the respective box portions 13 and 12 to the outside as described above, the discharged plate S existing inside the box portions 12 and 13 is forcibly pulled out. Further, it is possible to smoothly and reliably discard the discharged plate S accompanying the rotation of both the box portions 12 and 13.

3. Third Embodiment (FIGS. 6 and 7)
In the discharge box 10 of the first embodiment schematically shown in FIG. 6, the hinge 22 is arranged along a horizontal direction parallel to the discharge direction (indicated by an arrow A). The second box portion 13 had an opening 20 for receiving the discharged plate S on the side of the printing apparatus 1. However, the hinge 22 does not necessarily have to be parallel to the plate discharging direction A. For example, the hinge 22a is in a vertical direction orthogonal to the plate discharging direction A as in the third embodiment shown in FIG. It may be arranged along. In this case, when discarding the discharged plate S, the discharged plate box 10 is removed from the printing apparatus 1, and after opening the first box portion 12 and the second box portion 13 as shown in FIG. It is necessary to change the overall posture downward so that the openings 12a and 13a face downward, and drop and discard the internal discharge plate S. Alternatively, it is necessary to perform the operation of opening the first box portion 12 and the second box portion 13 after the plate-release box 10 is removed from the printing apparatus 1 and the opening 20 of the plate-release box 10 is directed downward. Even when discarding due to such a structure and action, the discharged plate S compressed in the discharged plate direction A in the discharged plate box 10 is folded in two in the width direction perpendicular to the discharged plate direction A, and more compactly folded. Like the first embodiment, the entire bulk can be reduced and discarded.

  Although not shown, the hinge 22a is arranged in the discharging direction A in addition to the case where the hinge 22a is arranged along the vertical direction orthogonal to the discharging direction A as in the third embodiment shown in FIG. However, they may be arranged along a horizontal direction perpendicular thereto. In that case, even if the compression means 6 does not compress the discharging direction, by folding the discharging box 10 in half at the time of disposal, the discharging plate S is folded in two to reduce the projected area onto the plane. It is possible to reduce the bulk.

  As described above, according to the plate ejection box 10 according to each embodiment of the present invention, even a large or wide printing plate can be disposed in a compact state with a simple disposal operation and disposed outside a normal size. The effect that it can be easily dumped into a box is obtained.
