Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an assembly method for rotary machining in a rotary perforation and cutting device, and particularly relates to an assembling method for rotary machining that can greatly reduce assembly time. .

[Prior Art] Continuous forms such as output forms for output devices such as computers are machined with perforations for separating and folding each set. The perforations and cuts (length of the cut and uncut parts) vary depending on the paper type (paper thickness, paper quality) and post-processing method, etc., and the blade with the corresponding number of cuts is selected, processed, and In the cutting process, a belt-shaped blade, which is the cutting part, is used to process continuous forms into sheets.

When perforating and cutting the continuous form using a form rotary printing machine, etc., a cylindrical sheet for rotary printing is formed by inserting and fixing a perforation blade of a thin strip into a groove provided at a predetermined position on the circumferential surface of the continuous form. The paper is passed between the paper and the cylindrical receiving cylinder arranged opposite thereto, and perforations and cutting are performed at regular intervals by rotating the processing and receiving cylinder. However, there are many different sizes of forms, and the circumference size for processing is generally an integral multiple of the top and bottom size of the form.

When making perforations and cutting with different top and bottom sizes, it is necessary to select and use a workpiece with a circumference that is an integral multiple of the perforations and cutting. In the conventional process assembly work, the machine to be used is placed on top of the printing machine using a crane or the like, and the gears for the process are set in mesh with the gears on the receiving cylinder. Thereafter, with the machining tool pressed against one side of the machine frame, the machining tool is completely fixed with a set bolt as shown in FIG. Such work cannot be performed unless the machine is stopped, which is a factor that increases the assembly time.

[Purpose] In view of the above points, the present invention sets the thin strip blade for machining outside the rotary perforation and cutting machine (hereinafter referred to as this machine), and immediately sets the thin band blade for machining to the machine. The purpose is to provide an assembly method for rotary machining that can be used.

[Structure] In order to achieve the above-mentioned object, the assembling method for rotary perforation and exchangeable machining for cutting of the present invention includes a groove provided in the generatrix direction of an exchangeable cylindrical rotary rotary machining machine. A processing assembly in a rotary perforation and cutting device that sets a strip-shaped thin blade and passes a sheet-shaped workpiece medium between this and a receiving cylinder, and perforates and cuts the workpiece medium. The machine frame of the processing device that holds the catch cylinder has a retractable piece at its tip that is attached to and detached from a pin protruding from a processing frame provided oppositely at both ends of the rotary processing machine. Processing an external assembly machine that is equipped with a telescopic arm and a processing cylinder fixing mechanism, and further has a function of inserting and fixing a receiving cylinder and a processing object that are in the same assembly positional relationship as the receiving cylinder of the processing device. It is installed separately from the machine, and first inserts and fixes the processing material to be used in the external assembly machine, inserts a strip-shaped thin blade into the groove, adjusts and fixes it in accordance with the receiving body, and then inserts the processing material into the machine. The pin is transferred from the external assembly machine to the processing insertion point of the processing device, and the pin is engaged with the retractable piece of the arm at a position away from the receiving cylinder, regardless of whether the processing device is running or stopped. When used for processing, the processing cylinder is moved and fixed at an operating position by the arm and the processing cylinder fixing mechanism, so that perforation and cutting can be performed.

Hereinafter, the assembly method of the present invention will be explained according to examples.

Figure 7 shows a conventional perforation machine, Figures 1 to 3 show the attachment/detachment and fixing mechanisms for processing, and Figures 4 and 5 show the structure of the external assembly machine. FIG. 6 shows an outline of the assembly method.

First, to explain the attachment/detachment and fixing mechanism for machining, as shown in Fig. 1, machining 1 has a groove in the direction of the cylindrical generatrix at a predetermined position on the outer and circumferential surface of a cylindrical shape. can be fixed, and processing frames 3 are provided oppositely at both ends for processing. Draw pins 8 are attached to the processing frame 3 so as to protrude outward, one side of the processing frame 3 is penetrated by the sewing machine barrel 1, and a driving gear is attached to the tip thereof.

On the other hand, the machine frame 4 of the processing device in which the receiving cylinder 2 is installed has a larger space in which the processed waste 1 can be accommodated, and the retractable piece is located at the place where the retractable pin 8 provided on the processed waste frame 3 is inserted. 9. An air cylinder IO having a piston rod forming an arm with a piston rod attached to the tip is attached to both sides of the machine frame 4.

Here, the retractable piece guide 15 serves to keep the retractable piece 9 oriented in one direction.

Further, as a method of fixing the machining scraps 1 from above, as shown in FIG. 2, U-shaped pieces 5. ′
is provided, and the square bar 6 is passed through this piece 5.5' so as to straddle the upper part of the processing waste frame 3. A screw 7 with a handle is screwed into this square bar 6 at a location corresponding to the center of the processed scrap frame 3. The screw hole passes through this rectangular bar 6, and the screw 7 passes through the rectangular bar 6 and directly presses the processing trunk frame 3, and with this force, it is possible to completely fix the processing waste 1 to the machine frame 4. .

Next, the structure of the external assembly machine will be explained. As shown in Figures 4 and 5, a space is provided in a frame 25 installed at both ends of a receiving barrel 2'' similar to the receiving barrel 2 of the processing device so that the processed scraps 1 can be set in the same positional relationship as the machine. Once the machining scrap 1 is set, the machining scrap 1 can be completely fixed to the external assembly machine frame 25 using the hexagonal bolt 22, square bar 23, and handle screw 24. , A gear 21 is attached to one side of the receiving barrel 2'' as in this machine, and meshes with the gear 2θ of the set machining scrap 1.

Furthermore, a hand crank 17 is provided on the other side of the receiving barrel 2',
When the receiving cylinder 2' is turned by hand, the machining waste 1 is also rotated through the gears.

In addition, the metal part of the frame 25 that bears the receiving cylinder 2' is eccentric, and has a mechanism that can adjust the inclination of the receiving cylinder 2' by adjusting the position of this metal. Adjust the angle to be the same as the inclination of receiver shell 2 of this machine. In addition, like the present machine, a receiving cylinder up and down lever 16 is added to the metal part to narrow or widen the distance between the receiving cylinder 2° and the processed scrap 1.

Furthermore, rubber rollers 18 are held by shafts 26 on both sides of the receiving cylinder 2' so as to face each other, and the rubber rollers are attached to and removed from the receiving cylinder 2° by a rubber roller attachment/detachment lever 19. This allows the sheet-shaped medium to be processed to be fed.

To explain the assembly procedure, set the machining scraps to be used in the machining scrap insertion space of the external assembly machine, and insert the machining scrap l into the gear 2.
0 and the gear 21 of the receiving barrel 2' installed in the assembling machine, and then press and fix the frame 3 of the processed scrap 1 to one side of the frame 25 of the assembling machine with the hexagonal bolt 22, and then It is completely fixed using the square bar 23 and the handle screw 24.

With the sheet-like processing medium wrapped between the rubber roller 18 and the receiving cylinder side, the operator sets the strip-shaped thin blade in the same manner as with this machine, and removes the processed waste and the receiving cylinder using the hand-cranked handle 17. , check the condition in which the workpiece medium is being processed, adjust the receiver cylinder up and down lever 16, determine the height of the blade for the processed waste 1, and finally fix the blade completely. , complete the blade setting on the external assembly machine.

As shown in Fig. 3(a), the machined waste 1 whose blade has been completely set is unloaded onto the machine at a position where the machined waste 1 is separated from the receiving barrel 2 of the machine and the gears do not mesh with each other. Wait there as shown in b), and when assembling, pull the rectangular bar 6 to one side of the machine frame using the air cylinder lO as shown in the same figure (C).
Finally, as shown in the figure (d), directly tighten the processing barrel frame 3 with the handle screw 7 to fix it. This will immediately allow perforations to be made.

[Effects] According to the assembly method of the present invention, assembly due to changes in perforation and cutting size requires only replacing machining scraps and fixing the machining scraps. It does not need to be used and can be easily completed in a short time, resulting in a significant reduction in assembly time.

In addition, in the case of a machine that has a plurality of machining units, for example two, as shown in Fig. 6, while the machine is operating, the vacant units can be assembled by the external assembly machine. Next, set the blade on the machining scrap to be used and fix the blade in the position shown in FIG. 3(d) as shown in FIG. 6(c).
Keep it on standby, stop the machine for the first time at the time of switching, move the air cylinders forward and backward for the unit in question and the unit that was previously used, and switch between units as shown in Figure 6(d). If this is done, the reduction in switching time will be even greater, and the operating efficiency of the machine will be increased.
