Description

  The present invention relates to a paper bundle reversing device capable of collectively reversing a paper bundle obtained by bundling a plurality of printing papers constituting a part of a printed matter.

  For example, a printed matter called a “page thing” such as a book or magazine is a collection of a plurality of sheets of paper (including signatures or pliers) arranged in the order of pages, and the work of collecting the plurality of sheets of paper. That is called collation. Currently, such collating operations at the time of bookbinding are generally performed by folding a multi-sided printing paper and then performing machine collation. For example, if the collating machine is a peller collating machine, a small number of copies In the case of bookbinding, or in the case of an extremely large or small size, the printing paper is cut for each page without being folded, and then collated with a peller.

  By the way, in the collation, for example, a paper bundle in which a plurality of sheets of the same content are stacked together is divided into pages from the beginning to the end, and the paper is picked from each paper bundle one by one in page order. It is put together in one printed matter. At this time, in order to overlay the next page of the paper on the paper, it is necessary to abut the surface of the next paper on the back surface of the first paper. However, in the case of a paper that has been multi-faced so as to be suitable for folding collation, the paper is cut for each page as a preliminary preparation for collating the paper, and then the paper is further cut. Half of the paper bundle divided into several parts must be turned upside down.

  Further, in printing double-sided printed materials such as leaflets, a device has been devised in which both sides of a sheet are printed by a single printing plate in which the front and back surfaces are alternately provided in multiple faces. However, when such papers such as leaflets are stacked in a paper bundle and cut and finished, the paper bundle of cut paper appears on the top or the back of the leaflet. , The front and back of each paper bundle is not unified. For this reason, for a paper bundle whose front and back are reversed, the paper bundle must be turned upside down to align the front and back with another paper bundle.

  However, in the work of reversing a paper bundle formed by bundling a plurality of printing papers, it is necessary to lift the paper bundle completely on the workbench and then turn the whole paper bundle upside down instantaneously and turn it over. For this reason, a burden is imposed on the operator, and for example, an operation at the time of reversing the paper bundle induces tendonitis such as a wrist. Further, it is difficult for a skilled craftsman to reverse a heavy paper bundle, and the paper bundle may be dropped during the reversal to crush the corners of the paper to make a wrinkle.

  Therefore, in order to reduce the burden on the operator associated with the reversing operation of the paper bundle, Japanese Patent Application Laid-Open No. 11-59979 discloses a signature adjustment / supply having a function of mechanically reversing the front and back of the paper bundle. An apparatus is described.

This signature adjusting / feeding device is provided in an autoloader that sends a signature into a pocket for a collating machine, and receives a certain amount of bundled signatures, In order to receive the unpacked signature stack and to reverse the stack, it has a pair of movable fork-like support portions opposed to each other up and down and a rotatable box that can rotate and retreat. According to this apparatus, after the bundle of signatures is placed on the cradle and unpacked, the rotating box is advanced, and the stack of signatures is supported by the rotating box. The top and bottom of the laminate is inverted.
JP 11-59979 A

  However, the above-described signature adjusting / feeding device is provided in an autoloader for sending a signature to a machine collating machine, and is extremely small in number suitable for bookbinding by peller collation. Since it is not specialized for printed materials, easily damaged booklets, or equipment for extremely large or small prints, the size of the device itself is large and the cost is expensive, so the collation is easy. There is a problem that it is extremely unsuitable for use.

Since the placement surface is held substantially horizontally, the holder member does not rotate due to the weight of the paper bundle and the placement plate does not tilt, and this inclination causes the paper bundle to slide down from the storage space. There is an effect that it can be prevented. In addition, when the holder member is in the reverse posture, the ceiling plate is abutted with the reverse posture stopper member, so that the ceiling surface is held almost horizontally, so the holder member rotates with the weight of the paper bundle. Thus, the ceiling plate does not tilt, and this tilt has an effect of preventing the paper bundle from sliding down from the accommodation space.

  According to the paper bundle reversing device according to claim 5, in addition to the effect achieved by the paper bundle reversing device according to claim 3 or 4, the height of the holder member is adjusted to the height of the work table by the lifting means. This has the effect of facilitating loading and unloading the paper bundle into and from the insertion opening of the holder member.

  Next, an example of how to use the paper bundle reversing apparatus 1 will be described with reference to FIGS. Here, FIG. 7 is a side view of the paper bundle reversing device 1 for explaining the rotation operation of the holder member 2, and corresponds to the left side of the paper bundle reversing device 1 shown in FIG. Specifically, FIG. 7A is a side view when the holder member 2 is in the normal posture, and FIG. 7B is a side view when the holder member 2 is rotated approximately 90 ° from the normal posture. FIG. 7C is a side view when the holder member 2 is in the reverse posture.

  When the paper bundle reversing device 1 is used, first, the caster 17 of the paper bundle reversing device 1 is rolled on the floor surface, and the paper bundle reversing device 1 is run. As shown in FIG. It lays down between the work tables 21 and 22 juxtaposed. At this time, the paper bundle reversing device 1 is laid side by side so that one work table 21 is located on the front side of the paper bundle reversing device 1 and the other work table 22 is located on the rear side of the paper bundle reversing device 1. Note that the heights of the two work tables 21 and 22 are substantially equal.

  After the paper bundle reversing device 1 is placed sideways, the leg portion 15 is expanded or contracted upward or downward by rotating the handle 16, and the height of the mounting surface 3a of the holder member 2 is substantially equal to the upper surface of the work table 21. Or slightly lower. Then, an end of the paper bundle B placed on the work table 21 on the front side of the holder member 2 is gripped by the operator, and the paper bundle B passes through the front opening 2a and the side opening 2b in the accommodation space 7. As shown in FIG. 7 (a), it is inserted while being slid in the direction of the arrow X and placed on the placement surface 3a.

  As shown in FIG. 7A, the paper bundle B accommodated in the accommodating space 7 is left protruding from the side opening 2b of the holder member 2 (see FIG. 1 and FIG. 1). (See FIG. 2). When the accommodation of the bundle of paper B into the holder member 2 is completed, the holder member 2 in the normal posture is rotated forward about the support shaft 8 in the counterclockwise direction of FIG.

  Then, the mounting plate 3 of the holder member 2 is separated from the reverse stopper 14 and is gradually inclined. At the same time, the back plate 5 of the holder member 2 is gradually inclined from the substantially vertical state, and the end on the back side of the holder member 2 gradually changes downward. When the holder member 2 is rotated forward in this way and the back plate 5 of the holder member 2 gradually becomes substantially horizontal, the side end (left side in FIG. 3) of the sheet bundle B is supported by the receiving surface 5a of the back plate 5. It will be received and supported.

  Then, as shown in FIG. 7B, when the holder member 2 is rotated approximately 90 ° from the normal posture, the front opening 2a is directed vertically upward, the back plate 5 is directed vertically downward, and the receiving surface. 5a is set to a substantially horizontal state. Thereafter, when the holder member 2 is further rotated forward by approximately 90 ° to have a reverse posture as shown in FIG. 7C, the ceiling board 4 is brought into contact with the forward rotation stopper 18 and the forward rotation of the holder member 2 is performed. I am stopped. When the holder member 2 is in the reverse posture, the ceiling surface 4a becomes the lower side of the placement surface 3a, and the paper bundle B is placed upside down on the ceiling surface 4a.

  At this time, the front opening 2a of the holder member 2 is directed toward the other work table 22 installed on the back side (left side in FIG. 7C) of the paper bundle reversing device 1. Thereafter, the end of the paper bundle B (see FIGS. 1 and 2) protruding from the side opening 2b of the holder member 2 is gripped by the operator, and the paper bundle B is removed from the front opening 2a and the side opening 2b. It is extracted while being slid to the upper surface of the other work table 21 in the direction of arrow X shown in FIG. As a result, the upside down operation of the sheet bundle B is completed.

  Incidentally, as described above, when the holder member 2 is rotated approximately 180 ° from the normal posture, the support shaft 8 is also rotated approximately 180 °. Then, the elastic band 12 in the state shown in FIG. 5 is wound around the outer periphery of the support shaft 8 as shown in FIG. Then, an elastic restoring force accompanying elastic deformation is accumulated in the elastic band 12. When the operator's hand supporting the holder member 2 in the reverse posture is released from the holder member 2, the elastic band 12 is elastically contracted and deformed, and the support shaft 8 rotates in the reverse direction (rotates clockwise in FIG. 5). Accordingly, the holder member 2 is reversely rotated.

  Due to the elastic restoring force of the elastic band 12, the holder member 2 that is reversely rotated is reversely rotated by approximately 180 ° from the reverse posture state shown in FIG. 4. When the holder member 2 assumes the normal posture shown in FIG. 3, the mounting plate 3 is brought into contact with the reverse rotation stopper 14 and the reverse rotation of the holder member 2 is stopped. As a result, the holder member 2 in the reverse posture is returned to the original normal posture, so that the preparation for inserting the next sheet bundle B into the accommodation space 7 of the holder member 2 from one work table 21 is completed. is there.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed. For example, in the present embodiment, the elastic restoring force of the elastic band 12 is used to reversely rotate the holder member 2 from the reverse posture to the normal posture. However, the source of restoring force that returns the holder member to the normal posture is described. Is not necessarily limited to an elastic band, and may be another elastic member such as a spring.

  In the present embodiment, the pantograph-shaped leg portion 15 configured to be vertically extendable and retractable by the rotation of the handle 16 is described as the mechanism for raising and lowering the gantry 13 of the chassis frame 10. However, other lifting mechanisms may be used as long as the height of the frame of the chassis frame can be changed to at least several stages.

  Further, in this embodiment, the mounting plate 3, the ceiling plate 4, the back plate 5 and the side plate 6 forming the holder member 2 are in the form of a flat plate, but these forms are not necessarily limited to a flat plate shape. It is not a thing, and what is necessary is just a member which can support the upper and lower surfaces of the paper bundle B in the placement plate and the ceiling plate, and any member which can support the end surface of the paper bundle B in the back plate. In the side plate, it is not always necessary if the support shaft can be fixed to the holder member without interposing the side plate.
