Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-fed sheet punching / manufacturing machine for punching a plurality of printing points printed on a sheet-fed sheet to manufacture a plurality of cards. The leaf sheet can be efficiently conveyed.

[0002]

2. Description of the Related Art Conventionally, a sheet group (sometimes referred to as a raw sheet) is sent by a punching die to punch out a plurality of printing points to manufacture a card group such as a telephone card and a credit card. There are punching machines that do this. In many of them, the single sheets are extracted one by one from the group of single sheets stacked in a bundle, and the single sheets are conveyed to a die part for punching by a belt conveyor or the like, A large number of cards are manufactured by punching out predetermined places (printing places).

[0003]

SUMMARY OF THE INVENTION In the above structure,
The sheet is fed into the punching die by the clamping device, the card is punched out from the sheet, the clamping device is returned to the original position, and a new sheet is clamped by the clamping device. However, even if the sheet is in an incorrect position during the clamping operation, the sheet will be pinched, and when the punching die is used to manufacture multiple cards from the sheet accurately, It was sometimes impossible to manufacture.

[0004]

Therefore, as a result of intensive studies by the inventor to solve the above problems, the present invention was applied to the front side of a punching die for punching a plurality of cards from a sheet. A belt feeding unit and a slide feeding unit are provided, the slide feeding unit is located between the punching die and the belt feeding unit, and a feed roller is provided in front of the punching die and a discharge roller is provided behind. A conveying clamp body is provided on one side in the width direction of the belt feeding unit, each of which is provided with a clamp that reciprocates between the belt feeding unit and the slide feeding unit, and that appropriately clamps and releases the sheet. A width direction positioning body that pushes out the sheet to the conveying clamp body side is provided on the other side in the width direction of the belt feeding section, and a front side positioning body that allows the leading end side of the sheet feeding direction to contact the belt feeding section is provided. Tena By was single sheet punching making machines, in which the exclusion of operation and the temporal waste, which make it possible to produce a plurality of cards accurately and from sheet-fed sheets.

[0005]

First of all, the sheet S is fed from the sheet feeder 24.
Are extracted one by one into the belt feeding unit 5 via a suction device or the like. Then, the belt feeding unit 5 is started, and the sheet S
Moves forward via the belt feeding unit 5, the leading edge of the sheet S contacts the front positioning body 13, and the position in the front direction is accurately set (see FIGS. 5 and 8A). Next, the width direction positioning body 10 pushes the sheet S from one side in the width direction (the direction orthogonal to the feeding direction), and the conveying clamp body B is brought into contact with the other side of the sheet S. (See FIGS. 6 and 7). In this way, the sheet S is secured on the belt feeding unit 5 in an accurate arrangement state. When the position of the sheet S is accurately determined, the front positioning body 13 moves above the sheet S,
This makes it possible to pass the single sheet S [Fig. 8
(B)].

Next, one side in the width direction of the sheet S is pinched by the clamps 7, 7 of the conveying clamp body B, and the sheet S passes through the slide feed section 6 as it is to the punching die A. It is sent [see FIGS. 8 (B) and 8 (B)]. 9 and 10 are plan views of the conveyance state of the sheet S by the conveyance clamp body B. Next, the sheet S is moved to the position of the feed roller Rf as it is, and the sheet S is carried into the punching die A while being sandwiched by the feed roller Rf. A plurality of cards s, s, ... Are punched from the sheet S by the punching die A (see FIGS. 11 to 16).

[0007]

According to the first aspect of the present invention, the belt feeding section 5 and the slide feeding section 6 are provided on the front side of the punching die A for punching and manufacturing a plurality of cards s, s, ...
And the slide feed section 6 is located between the punching die A and the belt feeding section 5, and the feed roller Rf is provided in front of the punching die A and the discharge roller Rb is provided behind it. The width of the belt feeding unit 5 is a transporting clamp body B having clamps 7, 7 which are provided and reciprocate between the belt feeding unit 5 and the slide feeding unit 6 to appropriately sandwich and release the sheet S. The belt feeding portion 5 is provided on one side in the direction.
A width direction positioning body 10 that pushes the sheet S toward the conveying clamp body B is provided on the other side in the width direction of the sheet feeding device. By using the sheet-fed sheet punching and manufacturing machine provided with the body 13, firstly, the step of punching and manufacturing a plurality of cards s, s, ... It is possible to minimize the number, secondly, it is possible to improve the precision of the punching manufacturing, and thirdly, there are various effects such that the structure of the apparatus can be made relatively simple.

To explain the above effect in detail, in the structure for conveying the sheet S to the punching die A, the belt feeding section 5 and the slide feeding section 6 are provided in front of the punching die A, Further, the conveying clamp body B is provided on one side in the width direction of the belt feeding portion 5 so as to reciprocate between the belt feeding portion 5 and the slide feeding portion 6. On the other side of the belt feeding unit 5 in the width direction, there is provided a width direction positioning body 10 for pushing the sheet S to the side of the conveying clamp body B, and the leading end side of the sheet S in the feeding direction contacts. A possible front positioning body 13 is provided.

Therefore, the single sheets S are taken out one by one from the place where the single sheets S, S, ... Occasionally, the frontal position of the sheet S is determined by the front positioning body 13 when the belt feeding unit 5 is started, and the sheet S is accurately positioned on the clamps 7, 7 of the transport clamp body B by the widthwise positioning body 10. It is intended to be able to be sandwiched between.

These operations are carried out almost instantly, and the sheet clamp S for conveyance passes the sheet S from the belt feed section 5 over the slide feed section 6 and the die A for punching.
By transporting it to a location, loss time in the process is eliminated and extremely efficient and high-speed punching work can be performed. Further, the belt feeding unit 5 and the slide feeding unit 6
The conveying clamp body B that reciprocates between the belt feeding section 5 and the slide feeding section 6 can also smoothly transfer the sheet S between the belt feeding section 5 and the slide feeding section 6, but the structure is not complicated here either. Can be simple.

Next, a second aspect of the present invention is, in the first aspect, the feed roller Rf includes a lower feed roller 14 and an upper feed roller 15 which can be appropriately separated from each other, and a lower discharge roller 16 which constitutes the discharge roller Rb. Since the upper discharge roller 17 is a single-sheet sheet punching and manufacturing machine capable of passing the single-sheet sheet S, the structure can be simplified.

To explain the above effect in detail, the feed roller Rf is composed of a lower feed roller 14 and an upper feed roller 15 which can be appropriately separated from each other, but in the discharge roller Rb, the lower discharge roller 16 and the upper discharge roller 17 are: The structure is simply such that the sheet S can pass through. Therefore, in particular, the lower discharge roller 16 and the upper discharge roller 17 are not of a type that separates them from each other, so that the upper and lower rollers of the discharge roller Rb are not separated or brought into contact with each other. The structure is such that it only passes between the lower discharge roller 16 and the upper discharge roller 17, and therefore the structure can be simplified.
