Abstract

PURPOSE:To eliminate a trouble when a signature is piled, by connecting the first cylinder to be in parallel with a rod of the second cylinder fixed to a machine bed and engaging a rack, provided in a rod of the first cylinder, with a pinion of a table supporting shaft so that a table rotary angle provides four kinds with 90 deg. being as a displacement angle. CONSTITUTION:A rod 2 of the second air cylinder C2 is fixed to a bracket 18 to which the first air cylinder C1 is mounted. The air cylinder C2 is fixed to a machine bed in a reverse direction to further in parallel with the air cylinder C1. While a rack 17 is provided in a rod R1 of the cylinder C1, engaging with a pinion 16 provided in the supporting shaft of a table 5. Stroke ratio of these two rods R1, R2 is set to 2 to 1, and a stroke length is determined so that a rotary angle of the table 5, generated by said ratio, obtains 180 deg. to 90 deg.. The table, whose rotary angle can be displaced to positions of +90 deg., + or -0 deg., -90 deg., -180 deg. by the combination of telescopic movement of these two rods, enables a small bunch of signatures to be smoothly inverted and piled.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to the 'A position for changing the direction 5 of an object carried onto a table to a desired direction. 11i
Printed paper that has undergone 1+ folding, such as a folded book, is collected in a predetermined section and made into a small bundle.

When creating a large bundle by loading the small bundles onto the table one by one and stacking them with the orientation of each small bundle alternately changed by 180',
This invention relates to a table reversing device suitable for applications such as the following.

b) Conventional technology Printed paper 1, for example, a folded book, is printed on the fold L1 side (
Commonly known as bag a), the one that is cut is the LI side (commonly known as bag a).

If you stack a large number of signatures in the same direction, the difference in thickness between the edges will become even more pronounced.
Stable accumulation cannot be expected, so for each desired number of accumulations (this is called a small bundle), the direction is reversed, that is, 1
If the direction of the small bundle is changed by 80'' and the small bundle is dried v1, the above-mentioned defect will be eliminated and a stable large bundle of signatures will be created.

By the way, the initial direction of the small bundle of signatures brought onto the table, that is, the direction of the line connecting the fold side and the cut side, is
Fold size, for example A3. A4, A5. There are two types depending on the size, such as A6, and there are cases where the direction is front and back, which corresponds to the carrying direction, and there are cases where the direction is left and right, which is orthogonal to the carrying direction.

Even if there is a difference in the orientation at the time of carrying in, it is desirable to create a large bundle of small bundles of signatures uniformly so that the direction is uniformly the former, that is, the front and back coincident with the carrying direction.

Therefore, there are also two types of table reversal that satisfy the above settings, and the former is supported by the loading position and its 18
Whereas it would be sufficient to alternately invert the table between 1111 and the 0° angular displacement position.

To deal with the latter, it is difficult to manipulate the 90" angular displacement of the table alternately on the left and right with respect to the loading direction. For the above reasons, to summarize the angular displacement required for reversing the table, the loading position can be adjusted by ±00". In this case, the table has three angles,
In other words, it is required to perform three-position angular displacement operations of +90', +180'', and -90°.

Now, in response to such technical demands, the conventionally known technical level was as follows.

As shown in JP-A-59-128158, as shown in FIG. 61-A and FIG. It was designed to engage with a rack attached to the table and convert the linear reciprocating displacement of the rod into the reversal angular displacement of the table.

C) Problems to be Solved by the Invention However, as stated at the beginning of page 5 of the publication, the above-mentioned known JA device does not allow the table to be fixed at 0° and 180°.
When converting between the angular displacement operation between 1 and 900, and the table angular displacement operation between
Not only does this require a lot of effort and time to operate, but there is also the concern that it reduces operational efficiency.

Furthermore, as mentioned above, since there is a 90' difference in the initial position of the table between the 180 angular displacement and the ±90° 90° angular displacement, the device is difficult to carry the small bundle of signatures onto the table. I have no choice but to always operate the button on the table surface,
As a result, the bottom signature of the small bundle of signatures escapes from the gap created between the table and the bushing.
There was a problem that caused problems that disrupted the normal delivery process.

The first object of the present invention is to eliminate the above-mentioned inconveniences and to easily change both the angular displacement of 180' and the angular displacement of +90' from the initial position of the table by simply changing the vJ of the fluid valve as necessary. It is an object of the present invention to provide a table reversing device having a low floor and capable of reliably and quickly sorting and converting.

The second objective of this invention is that as a result of the achievement of the first objective, the initial position of the table does not fluctuate;
It is now completely reliable to carry small bundles of signatures onto the table.
It is an object of the present invention to provide a table reversing device capable of eliminating troubles caused by defects in carrying in small bundles of signatures.

d) Means for Solving the Problems The structure of the present invention achieves the above-mentioned object. A drive system, and a second drive system in which a rod of a second cylinder is linked to the first cylinder, and the second cylinder is fixed to the machine base in parallel or in series on the same axis as the first cylinder. The stroke ratio of the two rods is 2:1, and the rotation angle of the table resulting from the comparison is 180':9.
0°, or, in addition to the above, at a point where a notch is carved in one edge of the table through which a button for carrying in a small bundle of signatures can enter close to the center of the table. be.

e) Operation If one of the drive systems is operated independently, the rotation angle of the table can be converted to two points, Oe' and +90''.

If the other drive system is operated independently, the rotation angle of the table can be converted to two points, 06 and -tao'.

By the combined operation of both drive systems, the rotation angle of the table is +90°-180'=-90° and 0°+o''=
It can be converted into two points o'.

Therefore, from the related operations of the two drive systems, the rotation angle of the table is always ±θ'' as the reference point.

+90',! It can be converted into three points: knee 90'1 and ±180''.

Note that since the initial position of the table rotation angle remains unchanged in any of the cases of conversion to the three points, the table can be provided with a notch into which the signature carrying button enters.

``) Embodiment A specific embodiment of this invention will be described in detail below with reference to the drawings.

The table 5 into which the small bundle of signatures 4 is carried consists of a combination of a central rectangular surface 51 on which the small bundle is placed, and a peripheral surface 52 thereof, both of which are integrally angled in the horizontal direction by means to be described later. On the other hand, the central rectangular surface 51 can also move up and down independently.

First, the center rectangular surface 51 is supported under the central part thereof by the end of a ram 6, and the ram 6 is supported by an actuator, for example, a hydraulic cylinder 8, which stands upright on a stand 7. The upper part 14 and lowering are possible, and the central rectangular surface 51
forms the same level as the peripheral surface 52 at its lowermost limit, and deposits the small bundle of signatures 4 therein, while transporting the small bundle of signatures to the outside at its lowermost limit.

On the peripheral surface 52 of the table 5, two parallel IJ notches 521 and 521 are carved on the negative side, that is, on the side in the direction in which the small bundle of signatures 4 is carried in, from the outer circumference to the center. This notch allows the pusher 10 to deeply enter into this notch when carrying the small bundle of signatures 4 on the shelf 9 onto the table 5 and carry the small bundle of signatures 4 onto the center rectangular surface 51. In particular, all the signatures can be carried in reliably without even the lower end signature of the small bundle 4 of signatures escaping.

In FIG. 2, on the other side of the peripheral surface 52 of the table 5, there is a backing plate 11 that can be adjusted in depth and depth, but since they are not directly related to the structure of the present invention, detailed description thereof will be omitted.

Now, in FIG. 2, an outer cylinder 1 is attached to the outer periphery of the actuator 8, which is the central support shaft of the table 5, through a bearing.
2 will be provided. One end of the outer cylinder is fixed to the peripheral surface 52 of the table 5 via a bracket 13, while a connecting rod 1 that hangs down from the central rectangular surface 51 of the table 5
For 4, it is received by the loose hole 15 so that vertical movement is free and horizontal movement follows 1! ! being touched. Therefore, if the outer surface 012 is rotated, the central rectangular surface 51 and peripheral surface 52 of the table 5 will also follow the rotation.

Further, a pinion 16 is provided in the middle of the outer cylinder 12, and the pinion is engaged with a rack 17, and the rack is attached to the tenth head R1 of the first sill C1 to form a first drive system.

Next, the 20th rod R2 of the second air cylinder C2 is fixed to the bracket (18) to which the first air cylinder CI is attached, and the second air cylinder C2 is oriented in the opposite direction and parallel to the first air cylinder C1. It is fixed to the machine base 7 to form a t52 drive system.

However, the stroke ratio of the two rods R1 and R2 is 2:1, and the table 5 generated by the comparison
The stroke length is determined so that the rotation angle is 180° to 90°.

In FIG. 3, (C,) is the first. 2nd both rods R
1 and R2 are both shortened, so for ease of explanation, if the position of this table 5 is set to the initial position ±Ou, then the table 7f in (a) with only the 20th rod R2 extended is The rotation angle is -180°, both mouths, R1, R2
The table rotation angle in (b) is 190° when both are extended, and (d) is when only the first lot FRI is extended.
The table rotation angle is +90°.In the above, if we assume that (b) where the table rotation angle is 190″ is the initial position of the table 5 ±0°, there will be a change of +90′ for each of the above, and as shown in the figure. As shown, (a) is -90°, (C) is +90°, and (d) is +180'.

Note that it is obvious that the same effect will be produced even if the stroke ratio of mouth, do, R1, and R2 is 2:1 and vice versa, 1:2.

g] Effects of the Invention As detailed above, in the present invention, the outer cylinder 12 corresponding to the central axis of the table 5 is moved by a complex operation of two reciprocating linear displacement drive systems connected in series with a stroke ratio of 2:1. By,
Without changing the engagement between the pinion 16 and the rack 17, four types of rotation angles with a displacement angle of 90, that is, +9
Since angular displacement to 0°, ±θ°, -90°, and -taOo positions is now possible, the operational effort and time are significantly reduced, and the ffl dynamic efficiency of the a-machine is improved.

Since the initial position of the table 5 remains unchanged during any angular displacement, deep notches 521 and 52 are formed on the table 5.
1 can be provided, and the button for carrying in signatures can be deeply advanced during that time, eliminating mistakes in carrying in signatures and improving labor efficiency.
