Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for stopping a rotating body in a counter stacker.

FIG. 1 shows an outline of a conventional counter stacker 4. When printed matter 1 is placed on a conveyor at a constant pitch and moved in the direction of the arrow, it is counted by a counting member 2, and a predetermined number is placed by a sorting member 3. Separated by number of copies. The printed matter 1 thus sorted is received by the upper receiving plate 5 which swings as shown by the arrow, and is formed into a small bundle, and this small bundle is passed from the receiving plate 5 to the upper receiving plate 6. , and is dropped onto the rotating body 7 located below it.

Such a rotating body 7 has a mounting plate 20 attached to the upper part of a shaft 10 supported by a rotational moon 141i on a substrate 9, and a side plate 18 is attached to an upper part of this mounting plate 20. A gear 16 is attached to the lower part of the shaft lO, which is equipped with a door plate 19 that is opened and closed by a cylinder or the like (not shown) when carrying out the east, and a push plate 8 that pushes the completed Daito out of the rotating body 7. I've been asked.

During this time, the segment gear 11 provided on the base plate 9 and oscillating around f-(-14@435) is engaged with the wheel 16, as shown in FIG. The tip of the piston rod 13 of an air cylinder '17 attached to the base plate 9 is pivotally supported at the tip of the arm 12, and the actuation of the cylinder 17 moves the piston rod 13 in the direction of the solid line or dotted arrow and the arm 12 at an angle. Shake within the range a.

This swinging of the arm 12 causes the gear 16, that is, 1g1
The rolling body 7 rotates 180 degrees in the left or right direction shown by the solid line or dotted arrow, and the cylinder 17 is operated each time the lower receiving plate 6 drops a bundle onto the rotating body 7. Thus, each bundle of printed matter is stacked with its orientation changed by 180 degrees.

By the way, such a rotating body 7 has a large inertial force, and the load due to the bundle of stacked printed matter also fluctuates, so its speed diagram rotates in the state shown in Fig. 6 v1, and when it stops, Because this occurs rapidly, the bundles inside the rotary body 7 move left and right when the rotary body 7 is stopped, resulting in a poor appearance and making it difficult to work in the packaging process that will be carried out later.Furthermore, the rotary body 7 vibrates due to the impact force when the rotary body 7 stops. However, this method has disadvantages such as shortening the life of the components of the drive mechanism.

In order to eliminate these drawbacks, attempts were made to attach a cushion mechanism to the cylinder or to throttle the air on the exhaust side of the cylinder in the latter half of rotation, but none of them were satisfactory. Therefore, the driver operates the throttle valve of the cylinder to reduce the rotational movement to d.
The tedious work of handling the carp was always required, and there were many other drawbacks, such as the need for unnecessary manpower.

This invention eliminates the drawbacks of the above-mentioned stopping device for a rotating body, and eliminates the problem of stopping the rotating body abruptly, thereby preventing the load from moving inside the rotating body from being hurried. In addition, it does not shorten the life of the drive (41:) product (and, moreover, the positive operation is automatically performed, saving one manpower for the weight. The object of the present invention is to provide a device for stopping a rotating body without causing any trouble.

In order to achieve the above-mentioned purposes, this multi-purpose brake disc is fixed to a rotating body, and a fluid actuating member is actuated to bring the brake pad into contact with the brake disc for braking. The present invention is characterized by the provision of a control section that operates in synchronization with the operation of an air cylinder for stopping the rotation of the rotating body.

An example of the present invention will be explained with reference to FIG. 3 and subsequent figures.

Since most of this embodiment is the same as the conventional one described in BLJ, the same reference numerals will be used to refer to the same parts, and the reference ψ will be omitted, and the different parts will be mainly explained.

Reference numeral 36 designates a brake disc formed as a part of the mounting plate 20, and a brake pad 15 attached to the fuselage bracket (12) 14 is placed close to this. It has become a county profit.

The t+45 diagram shows cylinder 17 and brake 4 cylinder 15.
The working fluid system of 21 is shown, and 21 connects the shaft 1 to the air source 26.
It is a solenoid valve for switching the air sent from (4/d) to the cylinder 17. Air 4 pipes 4o and 4t from this valve to the cylinder 17 are connected to the air pipes 4o and 4t, respectively.
．． 25 is placed i7, and this conductivity %4o, 4
1 and 2ii branches 42 and 43 are pilot ports 27a of the switching valve 27.

27b.

33 is the second air pressure (s kp/ryd), which is connected to the 4-channel pipe 44 and goes up to the lower 1c, and is compressed by 5, 4, 0.2, 9/(!4). 1st, 2nd and 3rd pressure regulating valves 28, 29, 30 and 0.2 to create used air
IJ (IJ) which momentarily releases the desired air of more than p/cr1 to the drain 34 and maintains the air pressure of 0.2 KW/cd.
1,1-] Valve 31 is equipped with a special device.

Downstream of the pressure regulating valves 28, 29, conduits 45, 46 branched from the full pipe 44 are connected to the switching valve 27, and the outlet of the switching valve 27 is connected to the constricted conduit 47 and the pressure regulating valve T. In the 300th stream, the 4qj4s branched from the dedicated pipe 44 are connected to the 1-, Lμ valves 32, and the brake pad 1 is
Made by 5! II! Iv) 1. I will explain the effects of the above.

FIG. 5 shows that air from the air source 26 passes through the tonnage valve 21 and the speed adjustment valve 24, enters the right chamber of the cylinder 17, rotates the rotating body 7 clockwise, stops the rotating body 7, and generates an electromagnetic valve 32
is located at the point where the exclusive pipe 48 and the brake pad 15 are connected, and an air pressure of 0.24/m acts on the brake pad 15, resulting in a non-braking state.

In this way, mark #ilJ is placed on the rotating body 7 in the right rotation position.
When the last part of the object is dropped, the solenoid valve 21 is switched by a signal from a control member (not shown), and air enters the left side chamber of the cylinder 17 via the speed adjustment valve 25, and at the same time, the air in the right side chamber passes through the speed adjustment valve 25. After being throttled by the throttle section 24 and slowly passing through, it is discharged to the outside from the exhaust pipe 23, and this throttle action controls the moving speed of the piston, that is, the speed of counterclockwise rotation of the rotating body 7. During such work, air is also introduced into the conduit 43, enters the inlet 27b and enters the switching valve 27, switches the switching valve 27, and passes through the conduits 45, 47 with a delay, while the solenoid valve 32 is switched by a signal from the mouth material. Then, the conduit 47 is connected to the brake pad 15, and an air pressure of 5 to 9/cd acts on the brake pad 15, and this pressure causes the brake disc 2 to
Apply the brakes to 0. The rotating body 7 braked in this manner is adjusted so that it completely stops after rotating 180 degrees, and the time required for rotation during this period is approximately 7 seconds. After 2 seconds have elapsed, the solenoid valve 32 is switched to 11゛L as shown in Figure 5, and as a result, the brake pad is in a non-braking state where an air pressure of 0.2 Kp/d is applied. Therefore, the remaining air is discharged to the drain 34 via the relief valve 31.

After that, contrary to the above, the clockwise rotation work will begin,
Regarding the cylinder 17, 10 is as described at the beginning of the description of the function, but at the same time, air is also introduced into the conduit 42, enters the switching valve 27 from the inlet 27a, switches the switching valve 27, and connects the dedicated pipes 46, 47. When the rotating body 7 has rotated 120 degrees, the solenoid valve 32 switches to connect the conduit 46 to the brake cylinder 15 in the same way as described above, and an air pressure of 4 Ky/cl, which is different from that when rotating to the left, is applied. brake pad 15
This pressure applies the brakes to the brake disc 20.

In this way, the pressure C4 (9/cd) acting on the brake pad 15 during clockwise rotation work is equal to the pressure (9/cd) during counterclockwise rotation work.
5Ky/d), but this is due to the following reasons. In other words, in FIG. 5, the left side of the piston has a larger area than the right side by the area of the piston rod 13.
Even if the same pressure 4 K9 / d is applied equally in the cylinder 17, it will be rotated with a greater force when rotating to the left than when rotating to the right. Therefore, if the braking force is the same as the applied force when rotating to the left, the brake pad 1 when rotating to the right is
5, the rotating body 7 will stop in the middle of rotation, and in order to avoid this, when rotating to the right, the brake force is approximately 20% weaker than when rotating to the left, that is, when rotating to the left. If it is 5Kl/d, it will be 41\y/o when turning clockwise.
Although it has to be /I.

In addition, as mentioned above, in addition to when the brake pad 15 is under a pressure of 4Ky7 (when rotating clockwise) and 5Kp/d (when rotating counterclockwise), a pressure of 0.2Ky/d is constantly being applied to the brake pad 15.
Since the gap between the brake pad 15 and the brake disc 20 is made small, the braking force can be applied smoothly during braking, and the sudden movement of the brake pad 15 toward the brake disc 2° is prevented. This prevents the generation of impact noise due to the impact upon sudden contact, thereby preventing deterioration of the workpiece.

The velocity diagram at the time of the above action is shown as v2 in FIG. It can be seen that frequent stoppages are suppressed.

This invention is as described above, in which a brake disc is fixed to a rotating body, a brake band is brought into contact with the brake disc by the operation of a fluid operating member, and braking is performed, and the brake disc is fixed to the rotating body. A restraining member is provided that operates in synchronization with the operation of the air cylinder for stopping rotation.
The rotating body does not stop abruptly, which prevents deterioration in the appearance of the package and wear and tear of drive mechanism parts, and furthermore, all operations are performed automatically without unnecessary human labor. It has many excellent effects.

It goes without saying that the structure, pressure conditions, etc. shown in the above embodiments are merely examples, and changes may be made thereto without departing from the scope of the claims.
