Description

  The present invention relates to a collection container that collects waste materials generated from an image forming apparatus, and more particularly, to a collection container that is environmentally friendly, a post-processing apparatus including the container, and an image forming apparatus.

  In performing an image forming operation, the image forming apparatus uses a sheet made of paper or the like for recording an image, and toner or the like for drawing an image on the sheet. In the process of forming an image on a sheet using these materials, finishing the image, and finishing the image formed product, unnecessary waste material is generated. Examples of such waste materials include toner (waste toner) remaining on an image carrier and transfer carrier used for forming an image used in the image forming unit, and a post-processing device attached to the image forming apparatus. In general, punch scraps from a punching apparatus are used.

  In the image forming apparatus, these waste materials are each collected in a collection container. The waste material collected in the collection container is usually transferred from the container directly to a disposal processing apparatus or recycling apparatus or transferred to a larger intermediate capacity container or bag for disposal or recycling.

  For example, Patent Document 1 discloses an image forming apparatus including a punch waste (waste material) collection container. However, in this conventional image forming apparatus, a collection container for collecting waste materials such as waste toner and punch scraps is formed of a material different from the collected waste materials. For this reason, the collected waste material is likely to be scattered around the periphery when it is transferred directly to a disposal processing device or a recycling device or to a larger container or bag for intermediate conveyance. Then, the scattered things were inhaled into the body and scattered around the surrounding area, which had to be cleaned.

  Therefore, Patent Document 2 discloses a technical content in which the collection container is formed of the same material as the waste material.

On the other hand, Patent Documents 3 and 4 describe a configuration in which a sensor is provided in the vicinity of the upper portion of the collection container to detect the collection container replacement time before the collection container is filled with punch scraps.

In addition, it does not spill waste materials and stain floors and hands.

  An embodiment of the present invention will be described with reference to FIGS. 1 to 9 as follows.

[Image forming apparatus]
First, a configuration example of an image forming apparatus according to the present invention to which the collection container of the present invention is applied will be described with reference to FIGS. 2 and 3.

  As shown in FIG. 2, the image forming apparatus 1 according to the present embodiment includes a printer unit (image forming unit) 2 and a paper feeding unit unit 3 disposed below the printer unit 2. An electrophotographic process section centered on the photosensitive member 4 is disposed at a substantially central position of the printer section 2. This electrophotographic process section has a configuration in which a charging unit 5, an optical scanning unit 6, a developing unit 7, a transfer unit 8, and a cleaning unit 9 are arranged around a photosensitive member 4 as a center.

  The charging unit 5 uniformly charges the surface of the photoconductor 4. The optical scanning unit 6 scans the optical image on the uniformly charged photoreceptor 4 and writes an electrostatic latent image. The developing unit 7 visualizes the electrostatic latent image written by the optical scanning unit 6 with a developer. The transfer unit 8 transfers the image recorded and reproduced on the photoreceptor 4 onto a recording medium. The cleaning unit 9 removes the developer remaining on the photoconductor 4 so that a new image can be recorded on the photoconductor 4.

  The residual developer removed by the cleaning unit 9 is sent to a later-described collection container via a collection path and collected in the collection container. The residual developer collected in the collection container can be discarded or recycled to another product later. The residual developer collection container may also be formed of a waste material to be collected, here, a material of the same system as the developer, as in the punch waste collection container 51 described later. That is, the residual developer collection container can be manufactured as a recycled product using, as a raw material, residual developer or fine powder toner that is out of product specifications generated in the manufacturing process of the developer. A known technique may be used as a method for producing a resin molded product using residual developer, fine powder toner outside the product standards, or the like as a raw material. Also, the residual developer collection container does not necessarily have to be made of residual developer or non-product-standard fine toner and raw material, and at least the residual developer can be made of the same material as the developer so that the residual developer can be recycled at the same time. It may be used.

  The residual developer collection container is set with a lid (residual developer collection container in the image forming apparatus 1) so that the collected residual developer is not scattered outside the container when the collected residual developer is discarded. It may be removed). This lid is also preferably formed of a material of the same system as the developer.

  A fixing device 20 is disposed in the upper part inside the printer unit 2. The fixing device 20 sequentially receives a sheet on which an image has been transferred, and fixes the developed image transferred onto the sheet by heat and pressure by a fixing roller and a pressure roller. Thereby, an image is recorded on the sheet.

  The sheet on which the image is recorded is further conveyed upward by the conveyance roller and is discharged from the sheet discharge unit 21 to the sheet discharge tray 22 or is reversed by the sheet discharge unit 21 and discharged through a conveyance path positioned at the top. The paper is transported to the opposite side of the paper tray, sent to a post-processing device 30 having an upper tray 32 and a lower tray 33, post-processed according to the presence or absence of post-processing, and discharged to the upper tray 32 or the lower tray 33. Is done.

  On the other hand, if double-sided image formation is designated, the image is again sent to the electrophotographic process section through the reverse conveyance path 23 from the middle of the conveyance path positioned at the top, and images are formed on both sides.

  Next, the paper feeding unit 3 will be described. The paper supply unit 3 includes a plurality of paper supply trays (recording medium supply units) 11 to 14. By including these paper feed trays 11 to 14, the paper feed unit unit 3 can accommodate various sheets as recording media, for example, separately for each size.

  The image forming apparatus 1 selects one tray from these paper feed trays 11 to 14. Further, the image forming apparatus 1 separates the sheets one by one from the selected tray and supplies the sheets between the photoconductor 4 and the transfer unit 8. Then, the transfer unit 8 transfers the image recorded and reproduced on the photoreceptor to the supplied paper.

  Here, the paper feed trays 11 to 14 will be described more specifically with examples. The paper feed tray 11 and the paper feed tray 12 are arranged in parallel with each other. A sheet feed tray 13 is disposed below the sheet feed tray 11 and the sheet feed tray 12, and a sheet feed tray 14 is disposed below the sheet feed tray 13.

  Further, the capacity of the paper feed tray 13 and the paper feed tray 14 are approximately the same. Further, the capacities of the paper feed tray 11 and the paper feed tray 12 are set larger than the capacities of the paper feed tray 13 or the paper feed tray 14.

  The paper feed unit 3 includes a first transport path 15 and a second transport path 16 in order to transport the sheets stored in the paper feed trays 11 to 14 toward the printer section 2. The first transport path 15 transports the paper stored in the paper feed trays 11, 13, and 14 toward the printer unit 2, and the second transport path 16 is stored in the paper feed tray 12. This is a path for conveying the sheet toward the printer unit 2.

  The first transport path 15 extends in the vertical direction along the frame 17 of the paper feeding unit 3. On the other hand, the second transport path 16 extends in the horizontal direction along the frame 17.

  Accordingly, the paper feed trays 11 to 14, the first transport path 15, and the second transport path 16 are efficiently arranged inside the paper feed unit section 3, and space saving of the paper feed unit section 3 can be achieved. It has been realized.

  When sheets are set in each of the paper feed trays 11 to 14, the target paper feed trays 11 to 14 are pulled out toward the front side of the main body of the image forming apparatus 1 to replenish the sheets.

  When the paper is jammed in the first transport path 15, the guide 15 a (indicated by the hatched portion in the drawing) constituting the first transport path 15 is placed on the front side of the user with the back side of the paper feed unit 3 as a fulcrum. To turn. Thereby, the paper jammed in the first transport path 15 can be removed. This removal operation is performed using a work space secured in advance between the first transport path 15 and the frame 17.

  Further, even when the paper is jammed in the second transport path 16, the guide 16a (indicated by a hatched portion in the figure) constituting the second transport path 16 is used as a fulcrum on the front side. To turn. As a result, the paper jammed in the second transport path 16 can be removed. This removal operation is performed after securing the work space below the second transport path 16 by pulling out the paper feed tray 11 and the paper feed tray 12 arranged in parallel to the user's front side.

  A manual paper feed unit 18 on which a relatively small amount of sheets are set is provided on the downstream side of the second transport path 16. There is a high possibility that a special sheet is set in the manual sheet feeding unit 18. This is because the sheet can be easily exchanged or set in the manual sheet feeding unit 18. A sheet can be supplied from the manual sheet feeding unit 18 to the second conveyance path 16 via the third conveyance path 21.

  The image forming apparatus 1 can further add a system by connecting optional devices such as the post-processing device 30 shown in FIGS. 2 and 3, the large-capacity paper feeding unit 60, and the image reading device 70 shown in FIG. It is. The post-processing device 30 will be described later.

  The large capacity sheet feeding unit 60 can be connected to the right side of the sheet feeding unit 3 as an optional device. The large capacity sheet feeding unit 60 is set to have a larger capacity than the other sheet feeding trays 11 to 14. In this case, the paper fed from the large-capacity paper feeding unit 60 is guided from the fourth transport path 19 to the printer unit 2 via the second transport path 16.

  The image reading device 70 is arranged above the printer unit 2, reads an original automatically or manually, and sends image data of the read original to the printer unit 2. During automatic reading, the original sheets are sequentially fed from the original supply tray 71.

  The image forming apparatus 1 having the above-described configuration is obtained from an image read by the image reading apparatus 70 attached to the printer unit 2 or an apparatus (for example, an image processing apparatus such as a personal computer) connected to the image forming apparatus 1 from the outside. Can be recorded and output as an image.

[Post-processing equipment]
Next, the post-processing apparatus according to the present invention will be described with reference to FIGS. The post-processing device 30 shown in FIG. 2 is arranged on the sheet discharge side of the image forming apparatus 1, and the control unit (not shown) of the image forming apparatus 1 determines a processing request input and set by the user from an operation unit (not shown). The discharged sheet is subjected to a predetermined post-processing according to a request and discharged. Here, as post-processing that can be performed by the post-processing device 30, staple processing, punch processing, and the like are common, but the post-processing device according to the present invention has at least a punch function.

  In the post-processing device 30 having a punch function, punch scraps (waste material) are always generated by performing punch processing on a discharged sheet. The generated punch scraps are sucked from the exhaust unit 54 having a fan shown in FIG. 1 and collected by the collection unit 50 so as not to be scattered in the post-processing apparatus 30. The punch scraps collected in the collection container 51 are later discarded or recycled. The punch scrap recovery unit 50 will be described later.

  As shown in FIG. 4, the punch device provided in the post-processing device 30 performs punch processing on the sheet passing between the dies 35 and 36, and the dies 35 and 36 have punch holes. 37 is provided, and a punch 38 is provided for each punch hole 37. That is, the punching process can be performed on the sheet by lowering the punch 38 in a state where the sheet exists between the dies 35 and 36.

  An eccentric cam 39 is used to move the punch 38 up and down. That is, the punch 38 can be reciprocated up and down once by rotating the eccentric cam 39 that is in direct contact with the upper end of the punch 38 or through a sleeve or the like. Although not shown, the punch 38 is biased upward (to the side in contact with the eccentric cam 39) by a spring or the like. The rotational driving force of the eccentric cam 39 is given by the motor 40, and the rotation amount of the eccentric cam 39 is detected by the timing disk 41 and the sensor 42.

  The configuration of the punch device used is not limited to the above example, and the punch device is configured to form a punch hole while rotating the die and the punch in accordance with the sheet conveying operation using the rotary die and the rotary punch. Etc. can also be used. Further, the number of holes that can be punched in the punching device is not limited. In addition, if the punch hole forming position can be set at a position other than the center of the sheet, a large number of punches and dies can be arranged in a direction perpendicular to the sheet conveying direction or can be moved. It can respond to the request.

  In the punching device, when punching is performed on the sheet, punch scraps are generated, and the generated punch scraps are dropped downward from the punch hole 37 of the die 35. For this reason, in the punch, a collection container 51 for receiving and collecting the falling punch scraps is set below the punch device.

  The post-processing device 30 is provided with a lock claw 31 and is fitted into the engaging portion 72 of the printer unit 2. Further, a positioning member 73 is provided in the printer unit 2 for alignment between the printer unit 2 and the post-processing device 30.

[Recovery container]
Next, the collection container according to the present invention will be described with reference to FIGS. Here, the recovery unit 50 provided with a recovery container 51 for punch waste generated by the punching device of the post-processing device 30 will be described. The collection unit 50 includes a collection container 51 and a dust box 52.

  The dust box 52 guides punch scraps falling from the punch hole 37 of the punch 38 of the punch device to the collection container 51.

  The collection container 51 is a collection container that collects punch scraps and is detachably attached to the punching device, and is made of the same material as the punch scraps, and here is formed of paper. The recovery container 51 is provided at the top with a recovery port for introducing the waste material into the container, and at the bottom with a suction port for suctioning the gas inside the container. The suction port is provided with a filter 53. Further, below the collection container 51, an exhaust unit 54 is provided which is connected to the suction port of the collection container 51 and discharges the gas in the collection container 51 to the outside. The exhaust part 54 is provided with a fan so that the gas in the recovery container 51 can be efficiently discharged from the suction port of the recovery container 51, and the waste material is more effectively prevented from adhering to the wall surface in the recovery container 51. be able to.

  As the collection container 51, a sheet (sheet) on which an image is formed by the image forming apparatus 1 is used. In this way, the recovery container 51 is made of paper used in the image forming apparatus and is formed into a cylinder or a cone as shown in FIG. 5, so that anyone can easily make the recovery container 51 without cost.

  The collection container 51 is formed by making the paper into a cylindrical shape or a conical shape (paper pack) and stopping the top or bottom of the cylindrical shape or the cone with a tape 51a. Here, the inner diameter of the bottom of the collection container 51 is larger than the punch scrap diameter and smaller than the filter diameter. The recovered punch scraps are removed or recycled together with the recovery container 51 after removing the filter 53.

  When the collection container 51 is filled with the collected punch scraps, it is assumed that the collection container 51 is discarded or recycled together with a new collection container 51 for use. For this reason, it is conceivable to store the replacement collection container 51 on the user side. If the collection container 51 is stored and used in the shape (cylindrical shape) in use, a large storage space is required. However, as described above, the collection container 51 can be easily formed using paper, and thus can be stored as it is without being formed. For example, the image forming apparatus 1 can be created by taking it out from the paper feed cassette.

  The dust box 52 is provided with a sensor for detecting whether the collection container is full of punch scraps. The type of sensor used is not particularly limited. The sensor is provided around the connecting portion between the dust box 52 and the collection container 51.

The filter 53 may be detachable from the bottom of the collection container 51. In this case, the filter may be reused together with the collection container 51 without being discarded. Alternatively, the filter may be formed of the same material as the punch scraps (for example, cardboard) and discarded or recycled together with the collection container 51. In this case, it may be configured not to be detached from the bottom of the collection container 51. Alternatively, the bottom of the recovery container may be closed, and the recovery container and the filter may be integrally provided by making a cut or the like in the bottom.

  Further, the filter 53 is not flat so that the punch scraps are not attracted to the filter 53 net to prevent clogging by punch scraps, as shown in FIG. The shape is preferred. With such a shape, the air escape structure is provided.

  According to the collection container 51 of the present embodiment, the gas inside the collection container is sucked from the suction port, and the waste material is not discharged to the outside of the container by the filter 53 at the bottom, but from the bottom to the top of the collection container 51. Accumulate inside. Therefore, it is possible to prevent punch scraps from sticking to the inner wall of the collection container 51 due to static electricity. Therefore, even if a sensor for detecting the fullness of punch waste is provided and provided near the upper portion of the collection container 51, the punch waste does not stick to the vicinity of the sensor and the sensor does not malfunction. Accordingly, the replacement can be performed when the collection container 51 is filled with punch scraps, and it is possible to prevent the collection container 51 from being replaced wastefully. And since the collection container 51 is formed of a material of the same system as the punch scrap, the recovered punch scrap can be discarded or recycled as it is without being transferred to another container. Collection is easy. Also, punch scraps are not spilled and the floor and hands are not soiled.

  The collection container according to the present invention is not limited to the structure shown in FIGS. 1 and 5 and may be shaped as shown in FIGS. Even in such a case, a filter similar to the above is provided at the bottom of the collection container.
