Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate discharge container in a stencil printing machine.

[0002]

2. Description of the Related Art In a stencil printing apparatus, information to be printed is recorded and formed on a base paper during printing. This base paper is wound around a printing drum. Ink that partially penetrates the base paper is supplied to the base paper from the inside, and the ink partially penetrates the recording paper that closely contacts the base paper to perform printing.

The used stencil sheet, which is a used stencil sheet, is peeled from the printing drum and conveyed by a pair of stencil sheet discharging rollers which are pressed against each other, and is stored in a stencil sheet container for storing the stencil sheet. In this way, the plate discharge base paper is sequentially fed into the plate discharge container, and when the plate discharge container becomes full, the operator is notified of that fact by a notification means such as an instruction lamp.

The operator removes the plate discharge container from the main body of the stencil printing apparatus and carries it to the disposal site of the discharged master paper, reverses the plate discharge container to discard the discharged master paper inside, and mounts it again on the main body of the stencil printing machine. In this way, the preparation for receiving the next stencil sheet is ready.

In order to automatically store the stencil sheet in the stencil printer in the stencil container, the stencil container is not provided with an upper lid. However, with the configuration without the top lid, when the stencil sheet is completely filled with the stencil sheet, the stencil sheet does not completely enter the container and is positioned in an unstable state on the upper part. When removed from the apparatus main body, there is a problem that the discharged sheet paper protruding from the box stains hands and clothes, or the sheet falls down to soil the floor.

As means for eliminating such inconvenience,
There are the following known technologies. . A lid is provided on the top of the stencil storage container, and when the stencil printer is attached to the stencil printing machine main body, the elasticity of the lid itself opens the lid to facilitate receipt of the stencil sheet.
When the stencil sheet container is filled with the stencil sheet and the stencil sheet container is detached from the stencil printing apparatus main body, a pressing member provided on the stencil printing apparatus body side is caused to act on the lid along with the detaching operation. A technique of preventing the stencil sheet from falling and soiling the floor by keeping the lid closed while keeping the lid closed (see Japanese Utility Model Publication No. 62-43811).

[0007] A pair of plate discharge rollers is arranged on the outer circumference of the printing drum, and a plate discharge receiving member is provided in a plate discharge path connecting the plate discharging roller and the plate discharging container. The plate discharging receiving member is rotatable 180 °, and at one rotation position. A technology that performs a function of guiding the stencil sheet from a stencil sheet discharging roller, and performs a function of compressing and storing the stencil sheet in the stencil sheet container at a position rotated by 180 ° from this rotating position (see Japanese Patent Laid-Open No. 5-318901).

[0008] In this technique, the plate discharge receiving member compresses and stores the plate discharge paper in the plate discharge container, and the plate discharge paper is sufficiently compressed and stored in the plate discharge container. The purpose is to prevent the outside of the stencil sheet from being contaminated and the stencil sheet from dropping when removed from the printing apparatus.

A technique for attaching a compression mechanism for holding and compressing a compression plate to an arm that is swung by a swinging mechanism, and compressing the discharged master paper in the discharge container (Japanese Patent Laid-Open No. 3-27893).
No. 2).

[0010]

In the above-mentioned known technique, since the lid is held in the open state depending on the elasticity of the lid itself, the lid cannot be maintained at a large opening angle over time. However, it will gradually become difficult to smoothly carry the stencil sheet into the stencil container, and when the stencil container itself is attached to the stencil printing machine body, the lid of the machine must be pressed while holding it by hand. You have to wear
There is also a problem in terms of operability.

In the above-mentioned known technique, since the plate discharge receiving member is rotated 180 ° to compress and store the plate discharge base paper, it mechanically interferes with the upper edge of the opening of the plate discharge container and rotates downward below the upper edge. It cannot move and cannot be compressed below the upper edge.

Therefore, as shown in FIG. 9, after the plate discharge receiving member is inverted, the stack height of the plate discharge base paper MT on the upper side is the opening of the plate discharge container 1 due to the elasticity of the stored plate discharge base paper itself. It is higher than the upper edge 1a. Therefore, when the plate discharge container 1 is detached from the stencil printing machine 2, the plate discharge base paper MT protruding from the opening upper edge 1a of the plate discharge container 1 may fall down as shown in FIG.

In the known technique described above, the mechanism is complicated and large-scale.

According to the present invention, when a stencil sheet container containing stencil sheet is removed from the stencil printing machine and is transported, the stencil sheet can be held without dropping in the middle of the stencil printing machine, and the construction is simple and the operability is good. It is an object of the present invention to provide a plate discharge container.

[0015]

The present invention provides (1). The stencil printing machine has a pair of plate discharge rollers which are in pressure contact with each other and conveys the stencil sheet separated from the printing drum, and a stencil sheet container which stores the stencil sheet stencil sheet. In the apparatus, both ends are supported on the upper part of the plate discharge container, and when the plate discharge container is mounted on the stencil printing apparatus main body, by engaging with a pressing member provided on the stencil printing apparatus main body side, a plate discharge path is formed. It is automatically rotated to a retracted position where it does not interfere and is held at this retracted position, and when the plate discharge container is detached from the main body of the stencil printing apparatus, the plate discharge papers stacked and stored in the plate discharge container. It is characterized by having a pressing member for pressing the discharged master paper that rotates to a pressing position to press the discharged master paper (claim 1).

(2). In the discharged stencil sheet storage container of the stencil printing machine according to (1), the rotation of the pressing member toward the retracted position or the pressing position is performed by utilizing the own weight of the pressing member itself. 2).

(3). In the stencil sheet storage container in the stencil printing machine according to (1) or (2), a biasing unit that applies a biasing force to the pressing member in a direction of rotating the pressing member from the retracted position toward the pressing position is provided. It is to be provided (Claim 3). (4). In the stencil container of the stencil printing machine according to (3), holding means for holding the pressing member in the retracted position is provided (claim 4).

(5). (1), (2), (3) or (4) In the stencil printing machine according to the stencil printer,
The plate discharge path is a path connecting the plate discharge roller and the plate discharge container, and on the plate discharge path is a plate-shaped member for conveying the plate discharge paper, one end of which is a support shaft parallel to the plate discharge roller. It is rotatably supported by and is reciprocally rotated around this support shaft, so that its free end faces the plate discharge roller side and about 180 ° from the plate discharge receiving position.

BEST MODE FOR CARRYING OUT THE INVENTION

(one). Description of Claims 1, 2, and 5 This embodiment will be described with reference to FIGS. 1 to 5.
FIG. 1 shows a part of the stencil printing machine relating to the present invention, in which a printing drum is designated by reference numeral 8 and a stencil ejection apparatus is designated by reference numeral 1.
Each is indicated by 0. The plate discharging device 10 forms a part of a stencil printing device. A stationary member 14 made of a member having an L-shaped cross section is provided in the plate discharging device 10.

The plate discharge container 1-1 is guided and moved by the stationary member 14 and positioned. In this example, magnetic force is used as a positioning means. That is, FIG.
, The magnetic plate MG1 is fixed to the outer wall portion of the plate discharge container 1-1, while the magnet M is attached to the vertical wall portion of the stationary member 14.
Fix G2.

The plate discharge container 1-1 is guided by the stationary member 14.
Is moved in the direction indicated by the arrow 15 and the mounting is completed, the magnetic plate MG1 is in close contact with the magnet MG2.
In this way, the position of the plate discharge container 1-1 is determined.

The plate discharge container 1-1 has a rectangular bottom.
Moreover, it is in the shape of a box with the upper part open. In FIG. 3, the stationary member 14 has a wall portion so as to be able to guide both side portions that penetrate the sheet surface of the plate discharge container 1-1.

In the printing process, the base paper 11 is wound around the outer circumference of the printing drum 8. However, when the printing process is completed, the base paper 11 wound around the printing drum 8 is used as a used discharge base paper M.
It becomes T. This plate discharge base paper MT is peeled off by a discharge member (not shown) as the printing drum 8 rotates in the direction of the arrow, and is discharged by a pair of plate discharge rollers 6 and 7 provided at the entrance of the plate discharge device 10 in pressure contact with each other. It is delivered onto the member 9.

The plate discharge receiving member 9 is located on the plate discharge path connecting the nip portion of the plate discharge rollers 6 and 7 and the upper edge of the opening of the plate discharge container 1-1, and one end thereof is at the plate discharge roller 6, 7
It is rotatable about a support shaft 12 having a longitudinal direction parallel to the axis of, that is, a direction perpendicular to the plane of FIG. The vertical position of the support shaft 12 is close to the plate discharge path, and the horizontal position of the support shaft 12 is outside the plate discharge container 1-1.

The plate receiving member 9 is reciprocally rotated at an angle of 180 ° by a rotary drive mechanism which is a combination of an electric motor and a gear. In FIG. 1, at the plate discharge receiving position shown by the solid line, the plate discharge receiving member 9 guides the plate discharge base paper MT and guides the plate discharge base paper MT into the plate discharge container 1-1.

In this manner, the plate discharge base paper MT is sequentially stacked from the leading end side thereof in the plate discharge container 1-1 while being naturally folded. Eventually, when the trailing edge of the plate discharge base paper MT passes through the nip portion of the plate discharge rollers 6 and 7, the fact that it has passed is detected by a detection means (not shown). Based on this detection information, the electric motor for driving the plate discharge receiving member 9 is driven, and the plate discharge receiving member 9 rotates 180 ° from the plate discharge receiving position shown by the solid line to reach the plate discharge discharging position shown by the two-dot chain line in FIG. . With this rotation, the trailing end of the discharged master paper MT is inverted and conveyed into the plate discharge container 1-1, and is compressed as it is filled with the discharged master paper MT.

A plate discharge guide plate 3 having a substantially arcuate shape is provided above the plate discharge receiving member 9 and fixed to the frame of the plate discharging device 10 along the rotation trajectory of the free end of the plate discharging receiving member 9. The rear end side of the plate discharge guide plate 3 has a structure substantially parallel to the plate discharge receiving member 9 located at the plate discharge position, and the base paper peeling claw 13 extends from the substantially arcuate portion to the parallel portion.
Is provided.

The base paper peeling claw 13 has a function to scrape the base plate MT, which is conveyed by moving in an arc shape by the plate receiving member 9, into the plate container 1-1. Reference numeral 1 in FIG.
As shown by 3a, 13b, and 13c, the support shaft 12 is provided at three locations in the longitudinal direction.

Thus, each time the base paper 11 is used, it is conveyed one by one into the plate discharge container 1-1, and eventually,
When the plate discharge container 1-1 becomes full, the plate discharge receiving member 9 compresses and stores it.

Since the volume of the plate discharge container 1-1 is known and the compressed volume of the plate discharge base paper MT to be stored is substantially fixed, the number of the plate discharge base papers that fills the plate discharge container 1-1 is counted. By such a method as described above, the timing at which the plate discharge container 1-1 becomes full is detected by the information from the detection means (not shown). When the operator is notified of the information that the plate discharge container 1-1 is full, the operator pulls out the plate discharge container 1-1 in the direction opposite to the direction of the arrow 15 shown in FIG. The plate discharge container 1-1 is removed from the apparatus main body, and the plate discharge container 1-1 is transported to a predetermined disposal location to discard the plate discharge base paper MT therein.

In this example, a pressing member for pressing the plate discharge base paper MT from above is provided in the plate discharge container 1-1 during the removal and the transportation work. This holding member is shown in FIG.
Reference numeral 4 is shown in FIG. The pressing member 4 has a substantially U-shape as a whole, and a base end portion thereof is pivotally attached to the plate discharge container 1-1 by a shaft 1b to rotate.

The pressing member 4 is composed of a frame body 4a which forms a main skeletal portion that rotates, and is integrally or integrally formed with the frame body 4a. As shown in FIG. 3, when viewed from the longitudinal direction of the shaft 1b. And a pressing portion 4b projecting at an angle of 90 ° with respect to the frame body 4a. In addition, of the frame 4a,
Engagement portions 4c made of plate-shaped members protruding outwardly in an ear shape are provided on the two opposing arm-shaped portions, respectively.

As shown in FIGS. 1 and 3, the plate discharge container 1-1.
Is held by the stationary member 14, the arm-shaped member portion of the frame body 4a of the pressing member 4 is in a vertically raised state as shown in FIG. The joint portion 4c is held by engaging with the engaging portion 5 as the pressing member according to the first aspect.

When the pressing member 4 is thus raised, the pressing member 4 is retracted from the plate discharging path connecting the nip portion of the plate discharging rollers 6 and 7 and the upper edge of the opening of the plate discharging container 1-1. In this state, such a position is called a retracted position.

The engaging portion 5 is, as shown in FIG.
It is provided in the frame of 0 corresponding to each engaged portion 4c. As shown in FIG. 1, the plate discharge container 1-1 is guided by the stationary member 14 and is pushed and moved in the direction of the arrow 15 by the engaging portion 5 to push the engaged portion 4c. That is, the pressing member 4 is rotated around the shaft 1b. The plate discharge container 1-1 is fixed to the stationary member 14
When it comes to be positioned by the magnetic attraction force of the magnetic plate MG and the magnet MG2 by being abutted against the vertical wall of
As shown in FIG. 1, the pressing portion 4b is horizontal or
Take a posture to the right of the posture shown in.

At this time, the pressing portion 4b of the pressing member 4 is rotated for conveying and compressing the plate discharge base paper MT, and the plate discharge receiving member 9 is rotated.
So as not to hinder the turning operation of the
In order to allow the sheet to escape, a relief portion 3a is formed in the horizontal portion of the plate discharge guide plate 3 and is bent upward in a convex shape. As a result, the pressing portion 4b is inserted in the escape portion 3a,
The interference of the plate discharge receiving member 9 with the pressing portion 4b is avoided.

In order to avoid this interference more reliably, the engaging portion 5 is made of an elastic material such as a plate-shaped spring material. That is, as shown in FIG.
The base end portion is fixed to the plate discharge device 10 and the free end side is made of a plate-like material which has a spring property and can be bent. Moreover, when the plate discharge container 1-1 is mounted at a predetermined position of the stationary member 14, the free end side of the engaging portion 5 elastically presses the engaged portion 4c.

According to this structure, when the plate discharge container 1-1 is placed at the predetermined position of the placing member 14, the engaging member 5 still exerts an elastic force on the engaged portion 4c. Therefore, the pressing member 4 is rotated in the counterclockwise direction further than the state shown in FIG. 1 around the shaft 1b, and the pressing portion 4b is surely set in the escape portion 3a. Therefore,
Even if there is a component tolerance or an assembly error, these errors are absorbed, and it is possible to reliably obtain a state in which the pressing portion 4b fits in the escape portion 3a.

The pressing portion 4b of the pressing member 4 is the frame 4a.
1 and 3, when the arm-shaped portion is in a substantially vertical state, it is bent 90 degrees toward the plate discharge rollers 6 and 7 and overhangs. Therefore, the plate discharge container 1
-1 is filled with the discharged master paper MT, and when the discharged master paper MT is pulled out in the direction of the arrow as shown in FIG. 4 in order to discard the discharged master paper MT, the pressing member 4 is rotated by its own rotation moment. Rotates about the shaft 1b in a clockwise direction.

When the plate discharge container 1-1 is detached from the stencil printing machine, the distance between the engaged portion 4c and the engaging portion 5 increases as the amount of drawing out the plate discharge container 1-1 increases. The amount of rotation of the pressing member 4 also increases, and when the engaged portion 4c and the engaging portion 5 are disengaged from each other, the pressing portion 4
Since b is in contact with the uppermost portion of the discharged master paper MT, the discharged master paper MT is pressed by its own weight. Thus, when the pressing member 4 is in the position shown in FIG. 4 for pressing the discharged master paper MT, the position of the pressing member 4 is referred to as the pressed position of the discharged master paper.

Since this operation is actually performed very instantaneously, the plate discharge base paper MT does not drop from the plate discharge container 1-1 during the rotation of the pressing member 4. Moreover, when the plate discharge container 1-1 is detached from the plate discharge device 10, the plate discharge base paper MT in the plate discharge container 1-1 is restrained by the pressing member 4 as shown in FIG. Even if handled easily, there is no danger that the discharged base paper MT will fall.

When the plate discharge base paper MT in the plate discharge container 1-1 is discarded in a trash box or the like, as shown in FIG.
When the pressing member 4 is tilted in the opposite direction, the pressing member 4 is opened by the arrow 16 so as to open the opening of the plate discharge container 1-1 by its own weight.
Since it rotates in the direction indicated by, it is possible to easily dispose of the discharged master paper MT.

When the discarding work is completed in this way, the emptied plate discharge container 1-1 is mounted on the plate discharge device 10. At this time, the pressing member 4 is pressed by its own weight so that the pressing portion 4b is above the opening of the plate discharge container 1-1. Rotate until it abuts the edge. The angle formed by the arm-shaped portion of the frame body 4a and the upper edge of the opening of the plate discharge container 1-1 at this time is referred to as the tilt angle θ of the pressing member 4 as shown in FIG. Good to set.

By setting such an angle, the stationary member 1 is used when the plate discharge container 1-1 is mounted on the plate discharge device 10.
As shown in FIGS. 1 and 3, when the plate discharge container 1-1 advances while being guided by the guide plate 4, the pushed member 4c is smoothly pushed by the engaging member 5 and the pressing member 4 is easily in the rising state. It becomes possible to put it in a state.

As described above, the plate discharge container 1-1 is replaced with the plate discharge device 1
When the sheet is discharged from the 0-stencil printing device, the plate discharge base paper MT is constrained by the pressing member 4, so that the plate discharge container 1-
The discharged stencil sheet MT will not drop while the sheet 1 is being carried, and the floor and hands will not be soiled due to the drop.

Further, since the rotating operation of the pressing member 4 is automatically and surely performed in accordance with the attaching / detaching operation of the plate discharging container 1-1 to / from the stencil printing machine, the pressing member 4 may be forgotten to be set or may be unset. There is no fear that so-called plate ejection jam will occur due to proper setting. Furthermore, since the structure of this example is very simple, it requires little space and is highly reliable.

(2). Description of Claims 3, 4, and 5 This embodiment will be described with reference to FIGS. 6 to 8.
In the plate discharge container described below, in FIG.
It has all the configurations related to the plate discharge container described above with reference to FIG. 4, and further has a new configuration. Therefore, the same components as those described in (1) above will be denoted by the same reference numerals, and the description of those components will be omitted.

In this example, as shown in FIGS. 6 to 8, elastic springs 18 are provided between both side portions of the plate discharge container 1-1 and the frame body 4a. One end of this spring is the frame 4
It is hooked on a hole 4d formed in a, and the other end side is hooked on a pin 1-1a provided on a side portion of the plate discharge container 1-1. This spring 18 moves the holding member 4 from the retracted position to the holding position when the rising position of the holding member 4 as shown in FIG. 7 is the retracted position and the tilted position as shown in FIG. 8 is the holding position. An urging force for rotating the urging member is given, and constitutes one example of the urging means in claim 3.

FIG. 7 shows a state in which the plate discharge container 1-1 is mounted on the stencil printing apparatus, and FIG. 8 shows a state in which the plate discharge container 1-1 is detached from the stencil printing apparatus. In this example, since the spring 18 is provided, when the engagement member 5 and the engaged portion 4c are disengaged from each other, the pressing member 4 has its own weight and the spring 18.
By the combined force of the force and the force, the position reaches the holding position shown in FIG.

Therefore, the stencil sheet stencil sheet MT is stronger than its own weight.
Is pressed, the pressing member 4 reliably presses the plate discharge base paper MT even when handling the plate discharge base paper 1-1 to discard the plate discharge base paper MT. It is possible to more reliably prevent the ejected base paper MT from jumping out.

In this example, holding means for holding the holding member 4 in the retracted state at the retracted position is provided. This holding means can have a coercive force stronger than that of the spring by sufficiently increasing the magnetic attraction between the magnetic plate 14 and the magnet 20.

(3) [Explanation Corresponding to Claim 5] As shown in FIG. 6 or as shown in FIG. 1, the plate discharge receiving member 9 is inverted by 180 °, and the plate discharge receiving position and the plate discharging position are shown. And the plate discharge rollers 6 and 7 at the plate discharge receiving position.
In the plate discharge container configured to receive the plate discharge base paper from the printer and compress the plate discharge base paper MT into the plate discharge container 1-1 at the plate discharge release position, at least the plate discharge receiving member 9 is at the lowest compression position. In the plate discharge release position shown by, the height of the upper edge of the outer wall of the plate discharge container 1-1 on the plate discharge rollers 6 and 7 side is set to be lower than that of the plate discharge receiving member 9 in the plate discharge release position.

In such a structure, since the height of the upper edge of the outer wall of the plate discharging container 1-1 on the plate discharging rollers 6 and 7 side is low,
The drop phenomenon of the discharged master paper MT as shown in FIGS. 9 and 10 easily occurs. In such a configuration, it is particularly effective to provide the pressing member 4 as in the above examples.

Further, since the rotatable plate discharge receiving member 9 is used, the pressing member 4 does not interfere with the operation of the plate discharge receiving member 9. Therefore, after the pressing member 4 is provided, if necessary, a compression mechanism for the discharged master paper MT in the plate discharge container 1-1 can be additionally provided to increase the storage amount of the discharged master paper.

[0055]

According to the first aspect of the invention, the stencil sheet container containing the used stencil sheet can be removed from the stencil printing machine and can be held without dropping during transportation when the stencil printing apparatus is transported. , And good operability are obtained.

According to the second aspect of the invention, since the pressing action of the pressing member is performed by its own weight, the structure is simple.

According to the third aspect of the present invention, since the pressing action of the pressing member is performed by the biasing means in addition to its own weight, the pressing function becomes more reliable.

According to the fourth aspect of the invention, the displacement of the plate discharge container due to the urging means is prevented.

According to the fifth aspect of the present invention, the stencil sheet is prevented from falling into the stencil sheet container into which the stencil sheet is carried by the 180 ° rotating type stencil sheet receiving member which is likely to drop.
