The present invention can be automatically supplied to a printing device for printing a predetermined mark on a part of a surface of a paper already bound, for example, a redemption mark contact or the like on one side of a calendar or the like.

It is often necessary to print on one side of a sheet of paper that has already been bound along a square in book type or pamphlet form.

For example, there are calendars that are sold for business by those who want to distribute them for advertising purposes.

The suppliers of these carers often print individual monthly calendars and bind them together, leaving a space on the advertisement sheet to be printed.

Once the carer manufacturer knows that it is an advertisement for printing on the space provided on the individual calender paper, the individual sheets must be rotated individually and transferred to a printing press for printing the advertisement. It is done manually, which brings a lot of time and tiredness.

Therefore, as a device for solving the above-mentioned work difficulties at a time, the turning of the paper and the printing operation is to be performed continuously and automatically as proposed by the present inventors as described in US Patent No. 4,768,810 have.

The above patent was a very useful invention for printing a large amount of paper quickly and for the convenience of the operator, but the inconvenience of supplying the bound paper manually by the end of one step was followed.

Therefore, an object of the present invention is to automatically carry out the process of lifting up the individual sheets of the bound binder and transferring them to the printing apparatus in such a way that the contents for performing such a printing operation, that is, the workpiece is wrapped with a metal pad at one corner. It is to provide a feeder capable of transferring the workpieces.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention is provided with a lifting element 110 which is lifted in a cyclic operation to lift the paper individually when the suction gripper 120 is raised together with the lifting element, and contact the chain 140 driven steplessly. The roller 100 is installed to move the paper below the contact roller 130, the contact roller 130 is lifted to the paper to the printing cylinder 150, the printing unit 100 and print to be made: the printing unit It is provided with a plate 210 positioned on one side of the (100) to guide the bound paper horizontally, and is placed on the conveyor 230 through which the upper portion passes to the upper surface of the plate 210 is required for feeding Stop means 240 is formed to stop the preparation in the starting position, the front of the cylinder 256 so that the paper prepared at a predetermined position by the stop means 240 is bite to the hook 221 installed in the chain 220 , The supply unit 200 is provided with a moving means 250 which is moved in a backward operation.

The printing unit 100 is a structure that allows a plurality of sheets of metal bands, as shown in the drawing, to print an advertisement display of desired contents at a specific position in the state where the corner is bound.

FIG. 1 is an overall apparatus diagram showing a process in which sheets bound along a corner are worked for advertisement display at a predetermined position with a calendar A which displays work contents as an example.

Accordingly, the printing unit 100 according to a configuration previously filed by the applicant of the present application is driven by a pair of one-cylinder printing cylinder 150 and the plate cylinder 151 which are designated as a blanket-transfer cylinder. It is a printing device.

The plate cylinder 151 transfers the image to a blanket of the printing cylinder 150 which receives printing ink from a conventional inking apparatus (not shown) and retransfers the image onto paper. Two cylinders 247 and 256 are rotatably mounted to the frame and driven by a drive motor.

The stack holder 160 for wrapping one end of the position where the paper is bound is placed together at a pair of chains 140 disposed at both corners of the calendar A and guided by two sprocket pins 141 and 142. The roller 15 installed to drive is repeatedly rotated at a constant speed.

And the gripper 120, which is connected to the vacuum not shown in the drawing so that the adsorption force intermittently acts is located at approximately the end of the paper to perform the operation to lift the paper in the raised state by the lifting element (110).

The stack holder 160 is a clamping device for fixing the paper to be printed, that is, the calendar (A).

The chain 12 driven to drive the contact roller 130 has a rotation path of which is indicated by a single dashed line, and at the same time forms a rotation path of the contact roller 130 in the region of the print cylinder 150, The shape of this rotation path is in the form of a circular head which is formed in parallel around the printing cylinder 150.

The structure for guiding the contact roller 130 in this area can appropriately form a guide groove or guide rail disposed in the frame.

The paper suction gripper 120 is static in relation to the rotational movement of the endless chain 140, but lifts and lifts the lifting motion moved upward while removing the suction force while lifting the upper part of the calender A. It can move around in relation to the element 10.

The gripper 120 is a lifting element 110, which may be made by lifting and lowering by a crank, or forward and backward moving means such as a cylinder, for lifting a sheet located on the top surface of the calendar A by using partial vacuum. It can be moved or arranged vertically by.

The operation sequence of the printing unit 100 made by such a component is briefly described as follows.

(a) in each step, the suction gripper 120 is placed on the uppermost sheet of the tarrender A and placed under partial vacuum;

(b) the suction gripper 120 is lifted from the paper to lift the individual top paper;

(c) the contact roller 130 disposed in the endlessly driven chain 140 moves between the completely lifted paper and the remaining paper stack;

(d) The individual contact rollers 130 move downward under the lifted paper, and the suction gripper 120 relaxes during this time, while the contact rollers 130 carry the paper toward the printing cylinder 150, while the suction The gripper 120 is placed on the paper again to grab the next paper;

(e) The contact roller 130 pressurizes the paper clamped on the print cylinder 150 and starts the printing process, wherein the contact roller 130 working with the print cylinder 150 acts as a contact roller. In the meantime, the lifting of the following sheets is carried out:

(f) The printing process is carried out by the just-printed paper which does not participate in the mechanism between the print cylinder 150 and the contact roller 130, together with the printed paper, the print cylinder 150 moves in an endless chain. While rotating in the opposite direction with respect to, at the same time, the next contact roller 130 is fully lifted up and then moves under the paper.

This process is repeated until all the sheets of the calendar A have been printed, after which the calendar A is replaced and the printing process of the new calendar A is performed.

Such a configuration of the printing unit 100 and the operational effects by the operation thereof are as already known by the inventors of the present invention.

The most important structural feature of the present invention is to install a supply unit 200 for automatically supplying the curry A to one side of the printing unit 100.

This is illustrated in FIGS. 2 and 3.

That is, the plate 210 is horizontally positioned so that the calendar A can be moved to the position of the stack holder 160 of the printing unit 100, and the calendars A loaded at the rear end are massed up to the stop position. The chain 220 is driven at both sides of the plate 210 so as to be able to bite the calender A to transfer the stack holder 160 one by one.

The pulley 231 and the sprocket 222 for driving the conveyor 230 and the chain 220 are respectively installed with a stepping motor (not shown) for driving the conveyor 230 and the sprocket 222 and rotated by a predetermined signal to move the calendar A. Make it work.

The transfer means 250 is configured to transfer from the position of the stop means 240 so that one calendar A can be hooked to the hook 221 formed on the chain 220.

Accordingly, as shown in FIG. 3, the driving rod 254 has a shape symmetrical with the lever 241 of the stop means 240, and uses another operation lever 251 having a locking surface 252 formed at an end thereof. When the cylinder 256 is moved forward and backward in the state in which the lower end of the operation rod 254 is installed in the flow rod 253 supported by the), the operation rod 254 hinged to the center pin 255 flows As a result of moving the operating lever 251 is to move the calendar (A) to the position of the hook 221.

That is, since the upper portion of the operating rod 254 is rotated clockwise in the drawing as the cylinder 256 moves forward, when the operating lever 251 is moved to the position of the stop means 240, the lever ( The upper end of the operating rod 254 is rotated about the center pin 255 by the movement of the cylinder 256 is retracted and the cylinder 256 in the retracted state by the 241 (A) is the flow rod 253 and the operation lever 251 installed thereon is repeated to transfer the operation lever 251 to the position of the hook 221 on the right side.

Although not shown, the hook 221 formed on the chain 220 remains elastically closed with a spring, but the metal band of the calendar A moved by the operating lever 251 of the transfer means 250. Is close to the inclined hook 221 at the inlet side is slightly raised and the catch is to be pulled in, and then configured to perform the closing position again.

In addition, a limit switch sw1 is installed at one side of the hook 221 to electrically detect the transport state of the calender A, so that the chain 220 supports the stack holder of the printing unit 110 by this support. It will be transferred to the position (160).

At this time, in order to guide the horizontal movement of the operating lever 251, as shown in FIG. 2, a guide lever 257 is installed at one end of the flow rod 253 and is guide groove 11 excavated in the frame 10. The operation lever 251 is constantly transferred as a result of being moved in a state where the roller 258 is fitted at the position of), thereby preventing the latch of the calendar A from being released during operation, and the plate 210. In the hook 221 is to be dug rail groove 211 to be transported in the state exposed to the upper surface.

In addition, the conveyer 230 is driven for the next supply while simultaneously transporting one calendar A by the chain 220 and the next calendar A of the stop means 240 in the ready position. It is operated so as to be caught by the lever 241. In addition, another limit switch sw2 is installed in the position of the engaging surface 242 of the lever 241 so that the following contents placed on the upper surface of the conveyor 230 reach the proper position. After the detection, the operation of the conveyor 230 is stopped to prevent further movement of the position.

The configuration of the lever 241 and the operating lever 251 is preferably at least two places on both sides of the calendar (A) so that the supply is made constant without twisting.

The cylinders 247 and 256 for operating the stop means 240 and the transfer means 250 may be any one that is moved forward or backward by energy or hydraulic pressure.

The supply unit 200 transferred to the printing unit 100 by such a configuration can be expected to automatically arrange the contents to be printed and to accurately supply at the appropriate time.

Although the contents completed by these devices are limited to the calendar A in the drawings and the description, the present invention is not necessarily limited thereto, and advertisements or various books having similar uses of the calendar may have the same effect.
