The present invention relates to a driving apparatus having a tooth clutch and a matching apparatus employing the same, and more particularly, to a driving apparatus and a matching apparatus employing the same.

The matching device is a device that sequentially stacks sheets printed on a single sheet according to the number of pages for binding booklets. In the matching device, a tray in which a plurality of sheets of the same page are stacked is sequentially arranged in the transverse direction according to the number of pages, and the sheet is pulled out by the swing arm from the tray and moved to the transport path. Therefore, in the conveyance path, the printed sheets sequentially drawn out from the tray are sequentially transferred while being stacked according to the number of pages.

Here, a plurality of pages of printing paper are grounded to form a unit of a station, and the unit includes a plurality of stations to form a unit, and the matching device includes a plurality of blocks. The plurality of blocks are driven together at the same time. For example, six stations may form one block, and the plurality of blocks are arranged laterally to form a matching device.

The number of blocks required depends on the number of pages in the book you want to create. In other words, when one station consists of eight pages and one block consists of six stations, 48 pages of printing paper can be collected by one block. And, if you use two blocks, 96 pages of paper can be gathered. If you want to create a 96-page book, you can use two blocks to complete the match.

However, in the conventional matching device, the blocks of each unit are driven together at the same time. Therefore, all the blocks of the matching device must be driven regardless of the page, and only some necessary blocks cannot be driven. Therefore, when a 96-page book is to be conventionally matched using, for example, a six-block matching device, the entire block must be driven even though only two blocks are needed. As such, although the number of blocks required is small, all of the blocks must be driven, which causes a lot of power consumption. In addition, the constant operation of blocks that are not needed may injure workers.

In order to solve this problem, a matching device has been developed that can control driving of a predetermined block among all blocks. The matching device is adapted to drive some blocks of a certain number of all blocks or all of the blocks. For example, three blocks can be driven from the front of the six blocks, and the remaining three blocks can be stopped. Alternatively, all the blocks must be driven. By doing so, partial power consumption can be reduced, but the selection range is very limited in that only a predetermined number of blocks must be driven or the whole must be driven. In addition, since a certain number of blocks are used continuously, only the blocks used are biased and used, thereby reducing the life of the matching device.

In addition, when some parts need to be replaced during the work, a problem arises that the work efficiency is greatly reduced because the entire line of the matching device has to be stopped to replace the parts.

The present invention has been made to solve the above problems, the drive unit that can selectively drive the blocks of each unit is less power consumption and use evenly as a whole to prevent shortening of the life due to one-sided use and It is an object to provide a matching device employing the same.

In addition, it is an object of the present invention to provide a matching device that can stably work by not driving blocks that are not required, and can prepare the next work for unused blocks, thereby improving productivity.

The first cam 151 coupled to the outer circumferential surface of the second cam 153 is caused by the eccentric rotational movement of the first cam 151 and is bound to the first shaft 160 and swinged. For example, the first shaft 160 may reciprocate in the up and down direction according to the swing of the first cam 151. The first link 163 rotates about the middle portion 163c of the first link 163 according to the vertical motion of the first shaft 160, and the second link 165 reciprocates in the horizontal direction. work out. Accordingly, the swing shaft 23 performs the swing reciprocating motion by pendulum movement of the second shaft 167 connected to the second link 165. As the swing shaft 23 performs a swing reciprocating motion, the first and second swing arms 10 and 11 operate to pick up paper.
