Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention does not stop the rotary printing machine or the like when the stacker (automatic binding machine) device of the destination is temporarily stopped in the middle of the conveyer of the print signature such as the rotary printing machine. The present invention relates to a discharge and storage device for printed matter signatures, which temporarily discharges printed matter signatures on a conveyer conveyor and stores the printed matter signatures in alignment and overlapping.

[0002]

[Prior Art]

 Conventionally, in a stacker device that bundles printed matter signatures and supplies them to the bookbinding process, for temporary suspension within a few minutes such as misalignment of printed matter signatures, paper jam or replacement of binding strings, In order not to stop the rotary printing press, etc., a temporary discharge storage device for printed signatures is provided in the middle of the transport conveyor between the rotary printing press etc. and the stacker device. Partly ejects printed matter signatures with a descending conveyor that rotates downward around the center and an elevator that rotates upwards around the end, and has an appropriate signature receiving plate and signature applying plate. The signature storage box was often equipped with a discharge and storage device for printed matter signatures, which stores the discharged printed matter signatures in a horizontal or vertical alignment and stacking them on top of each other.

[0003]

[Problems to be solved by the device]

 Regarding the conventional discharge and storage device for printed signatures described above, there is a problem with the signature storage box that has appropriate signature receiving plates and signature patch plates, and the function to lower and move the signature receiving plate up and down. Since the signature storage box and the signature storage box have the function of moving down and up, the function of the signature storage box is not precise. Therefore, although there is no problem when the number of printed signatures discharged is small, there was a problem that the printed signatures discharged above a certain limit could not be aligned horizontally or vertically. That is, it takes time to process the printed signatures such as damage or alignment.

[0004]

[Means for Solving the Problems]

 The present invention is a transfer conveyor for a printed matter signature that has been printed and folded by a rotary printing machine or the like. It is located continuously at the end of the conveyor and moves vertically down by an electric chain, etc. to receive the ejected printed matter signatures and stack them horizontally. A discharge and storage device that is composed of a signature vertical backing plate for horizontally aligning printed signatures and a distance setting sensor fixed at the upper position of the signature vertical backing plate. A distance setting sensor that detects the distance to the top printed matter signature moves the electric chain etc. by the signal and moves the signature horizontal receiving plate down and up and down, so that the signature horizontal receiving plate is stacked horizontally. Combine multiple copies of printed signatures By keeping the upper height at almost the same level as the descending conveyor, the printed signatures on the transport conveyor are temporarily ejected and the printed signatures are horizontally aligned and superposed. It will provide a discharge and storage device for printed signatures.

[0005]

[Action]

 As shown in Fig. 1 and Fig. 2, printed matter signatures that have been printed and folded by a rotary printing press are discharged in a state of overlapping sashimi and conveyed on the descending conveyor (10). The signature horizontal receiving plate (20) is positioned continuously at almost the same height as the descending conveyor (10) so that the printed matter signature (50) being conveyed is folded into the signature horizontal receiving plate. The printed matter signatures (50) can be horizontally aligned and stacked simply by colliding the signature vertical contact plate (30) which penetrates the (20) and is fixed. However, some print signatures (50) overlap the signature horizontal support plate (20) and the top of the print signatures (50) is higher than the descending conveyor (10). Then, as shown in FIG. 3, the printed matter signature (50) is raised between the descending conveyor (10) and the signature horizontal receiving plate (20), and the printed matter signature (50) is leveled. It is impossible to align and stack.

According to the present invention, the distance setting sensor (40) fixed at the upper position of the signature vertical contact plate (30) detects the distance between the sensor (40) and the uppermost printed matter signature (50). Then, the electronic chain (21) is moved by the signal to lower and move the signature horizontal receiving plate (20) up and down, and a large number of printed materials are horizontally stacked on the signature horizontal receiving plate (20). The top of the signature (50) is maintained at almost the same height as the descending conveyor (10).

【Example】

 FIG. 1 is an explanatory view showing the structure of a discharge and storage device for a printed matter signature according to an embodiment of the present invention. That is, in the middle of the conveyer conveyor (11) conveyed in the direction of arrow A of the printed matter signature (50) that has been printed and folded by a rotary printing machine (not shown), centering around the start end. It descends and rotates in the direction of arrow B to eject the printed matter signature (50) and the descending conveyor (10), which is located continuously at the end of the descending conveyor (10) and is connected by the electric chain (21). The printed matter fixed by penetrating through the signature horizontal receiving plate (20) and the signature horizontal receiving plate (20) that vertically moves down and receives the discharged printed document signatures (50) and horizontally aligns them. Discharge storage device consisting of a vertical signature plate (30) for aligning the signatures (50) horizontally and a distance setting sensor (40) fixed at the upper position of the vertical signature plate (30). However, the distance setting sensor (40) that detects the distance between the sensor (40) and the uppermost printed matter signature (50) moves the electric chain (21) with the signal, and The flat support plate (20) is moved down and down in the direction of arrow C, and the height of the top of the multiple copies of print signatures (50) is horizontally stacked on the signature horizontal support plate (20). This is a state in which the height is maintained at almost the same constant height as the descending conveyor (10).

Regarding the descending conveyor (10) which descends and rotates about the starting end of this embodiment, a conventionally known descending conveyor (10) that fits the size and shape of the printed matter signature (50) is used. 10) is used. In this case, if necessary, a holding conveyor (not shown) may be provided on the descending conveyor (10), and an ascending conveyor (not shown) may be installed on the downstream side of the descending conveyor (10) so as to rotate around the terminal end. ) Etc. can also be used together.

Regarding the signature horizontal receiving plate (20) that moves down and up and down by the electric chain (21) of the present embodiment, a conventionally known appropriate folding that fits the size and shape of the printed matter signature (50) is used. It uses a horizontal receiving plate (20). In this case, in the discharge storage device of the present invention, there is no need to use a conventional signature storage box (not shown) or the like because printed signatures are not aligned and there is no risk of scattering. As for the electric chain (21) equipment, it is possible to use other appropriate descending and descending equipment such as rack and pinion equipment.

Regarding the signature vertical patch plate (30) which is fixed by penetrating through the signature horizontal support plate (20) of this embodiment, two metal rod-shaped signature vertical patch plates (30) are used.

[Effect of the device]

 As shown in the above-described operation and embodiment, in the printed article signature storage device of the present invention, the distance setting sensor fixed at the upper position of the vertical signature plate of the signature separates the sensor from the uppermost printed matter signature. Detecting the distance, the electric chain is moved by the signal and the signature horizontal support plate is moved down and up and down, and the top part of the multiple copies of printed signatures horizontally stacked on the signature horizontal support plate is detected. Since the height is maintained at almost the same level as the descending conveyor, the printed matter signatures that are discharged in the state of overlapping sashimi-like parts and conveyed on the descending conveyor are placed on the signature horizontal support plate. Thus, it is possible to align the plates horizontally and stack them by simply passing through the horizontal plate of the signature and colliding with a fixed vertical plate of the signature. In other words, the printed signatures are not damaged and there is no need for processing such as organizing.

The printed article signature discharge storage device of the present invention is a stacker (automatic binding machine) device that binds the printed signatures and supplies them to the bookbinding process. For a temporary suspension within a few minutes, such as when replacing the printer, without temporarily stopping the rotary printing machine, the printed matter signature on the transport conveyor is temporarily discharged and the printed matter signature is leveled. It can be aligned and stacked. In addition, the inventors of the present invention installed the discharged and stored apparatus for the printed matter signature of the present invention in a double manner in the left and right directions of the conveyance direction of the printed matter signature so that the stacker apparatus can be temporarily stopped for several minutes or more. In addition, it is also possible to provide the discharge and storage device for the printed matter signature of the present invention in a multi-sequential type of two or more. It is also possible to provide the discharged and stored apparatus for the printed matter signature of the present invention on another transport conveyor such as a card or a paper container blank, which is transported in a state in which sashimi-like parts are partially overlapped.
