Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to a paper feed shelf for a collating machine.

(Prior art) As is well known, a collating machine is used to arrange printed sheets of paper from the first page to the last page so that they are connected in order, collect them one by one, and combine them into one book. do. For this purpose, a plurality of paper feed shelves are arranged side by side, and the paper is placed on each paper feed shelf in order, and the paper fed from each paper feed shelf is stacked in order to obtain the required number of paper feed shelves. Perform collation.

By the way, all of the paper feed shelves provided in one collating machine are not always used, and if there are more paper feed shelves than the number of pages to be collated, there are paper feed shelves that are not used. That is clear.

Therefore, if you accidentally place paper on a paper feed shelf that is not in use, when you collate the paper, you will naturally end up with a bound book with missing pages. This is especially true in cases where the collation function is highly automated, and the paper feed shelf rises when collation begins, and when it runs out of paper, it automatically lowers and returns to the standby position, waiting for paper to be reloaded. The above-mentioned errors are extremely easy to occur.

(Problem to be solved by the invention) This invention easily displays the position of an unused paper feed shelf when it is fixed in the standby position, and
The purpose is to make it difficult for paper to be placed on it and to prevent paper from being placed on it by mistake.

(Means for solving the problem) This invention provides a lock shaft that locks the shelf body which is rotatably supported around the fulcrum shaft, and also provides a protrusion on this lock shaft to fix the lock shaft. The shelf body is characterized in that a hole is provided on the surface of the shelf body through which the protruding part exits from the surface of the shelf body when connected to the shelf body.

(Example) An example of this invention will be explained with the help of diagrams: 1
is a shelf main body on which the sheets to be collated are placed on the surface, and a fulcrum shaft 3 that spans a fixed part of the collating machine main body, for example a pair of side plates 2 facing each other (one side plate is omitted). It is said to be able to rotate freely around the center. 4 is a paper feed roller, and 5 is a reference plate that regulates the position of the leading edge of the paper.

The paper placed on the shelf body 1 is discharged from the shelf body 1 in the direction of arrow P by the rotation of the paper feed roller 4. As the paper feeding progresses, the shelf body 1
The distal end side is raised about the fulcrum shaft 3 by a spring or the like (not shown). These structures are not particularly different from ordinary paper feed shelves of this type.

According to this idea, a lock shaft 7 is provided whose tapered tip can be inserted into and removed from a hole 6 formed in the side plate 2. This locks the shelf body 1 from rotating around the fulcrum shaft 3 when inserted into the hole 6. This lock shaft 7 is provided with a torsion spring 8.

The torsion spring 8 has one end engaged with the back surface of the shelf body 1 and the other end engaged with a pin 9 set up on the lock shaft 7, thereby applying a rotational force to the lock shaft 7 in one direction. There is. Torsion spring 8
Furthermore, a pin-shaped protrusion 10, for example, is provided.

For the paper feed shelf to be placed on standby, the tip of the lock shaft 7 is inserted into the hole 6 as shown in the figure. At this time, the protrusion 10 is such that the lock shaft 7 is rotated by the torsion spring 8 so that it protrudes from the hole 11 formed on the surface of the shelf body 1 to the surface of the shelf body 1.

The protrusion 10 protruding from the hole 11 elastically abuts the rear edge of the hole 11. As a result, the lock shaft 7 is elastically held in its position without being rotated any further. In this state, the shelf body 1
The movement around the fulcrum shaft 3 is restricted to the side plate 2. Therefore, even if another paper feed shelf starts feeding paper, this paper feed shelf does not rotate for paper feeding and remains in a locked state.

In the above state, that is, the state shown in the figure,
A protrusion 10 is visible protruding from the surface of the shelf body 1. Therefore, the protrusion 10 exhibits a display function,
With this, it is immediately clear at a glance that this paper feed shelf is in a dormant state. Furthermore, even if an attempt is made to load paper onto the shelf main body 1 of this paper feed shelf, the protrusion 10 will prevent the paper from being loaded.

To unlock the locked shelf body 1, first move the lock shaft 7 to the torsion spring 8.
The protrusion 10 is sunk below the hole 11 by rotating against the elastic force of the protrusion 10. Then, pull it toward you and pull the tip out from hole 6. As a result, the lock of the shelf body 1 by the lock shaft 7 is released.

(Effects of the invention) As detailed above, according to this invention, the shelf body that is to be discontinued is locked so that it cannot be rotated by the lock shaft, and the protrusion provided on the lock shaft is Since the lock shaft protrudes from the surface of the shelf body at the lock position,
This protrusion can be used to indicate that the paper feed shelf is at rest, and the protrusion can also be used to prevent paper from being loaded.
