処理ユニットである１３に給送されるものである。In this conventional device, as the rotating disk 9 rotates, the rotating disk 9
The bottle 10 fixed to the arm 8 also rotates, but at this time the arm 8
Since the bottle 10 moves while sliding inside the notch,
Arm 8 performs a rocking movement. Accordingly, the lever 7 fixed to the arm 8 also swings, and the kicker 2 reciprocates on the table 3 via the bin 6a'-lever 7, the bin 6, and the connector 4. The reciprocating movement of the kicker 2 sends out the corrugated paper pieces 1a one by one, which are then sandwiched between a pair of rotating feed rolls 12 and fed to the next processing unit 13. It is something.
しかしながら上記従来の製函機では、次のような問題点
があった。即ち、第７図に段ボール紙片をキックしてい
る状態を斜視図にて示している。However, the conventional box making machine described above has the following problems. That is, FIG. 7 shows a perspective view of a state in which a piece of corrugated paper is being kicked.
段ボール、紙片は、次に述べるように幅方向平行な姿勢

る段ボール紙片１から受ける荷重分布、摩擦抵抗が幅方
向で均一にならず、幅方向に給送力のアンバランスが生
じること等によって起こるものである。As described below, cardboard boxes and pieces of paper are not necessarily fed parallel to the width direction, but may be fed obliquely as shown by the dotted line in FIG. This is due to the frictional resistance between the corrugated paper piece 1a and the top of the table 3, and the frictional resistance between the corrugated paper piece 1a and the top of the table 3. This occurs because the load distribution and frictional resistance received from the stacked corrugated paper pieces 1 are not uniform in the width direction, resulting in an imbalance in the feeding force in the width direction.

。Further, such a defective phenomenon of oblique feeding may occur not only in the above-mentioned paper feeding section but also due to an imbalance of forces in the width direction during processing in each unit. If corrugated paper pieces are fed diagonally, printing units will experience printing twists and blurring, while punching units will experience punching twists, and if the amount of inclination is large, each unit will This is inconvenient because jam amps occur.

It is located between 7 and 18. The detection device used may be similar to that described above. However, in this example, unlike the previous example,
Rather than using the reflected wave from the corrugated paper piece 1a,
As shown by the dotted line in the figure, the receiver 14-2 may be arranged on the back side of the corrugated paper piece 1a, and a transmission sensing method may be adopted. The transmission method is a type in which a sensor on the wave transmitting side and a sensor on the wave receiving side are opposed to each other, and an object to be detected travels between the two sensors, as shown in FIGS. 4(c) and 4(b).

力端子である。FIG. 3 shows a perspective view of the arrangement of the acoustic detection pickup of the example shown in FIG. 1, and also shows a detailed block diagram of the arithmetic unit 16. In the figure, 19 is an oscillation power supply device, 20 is an amplifier that amplifies the switch signal sent from the delivery device 14-2, that is, the voltage of the step response signal, and 21 is a feeding speed signal of the corrugated paper piece 1a by a measuring means such as a rotary encoder. The transmitter 22 receives the signals from the plurality of amplifiers 20 and the feed speed signal transmitter 21, and calculates the amount of inclination of the corrugated paper piece 1a from the time difference between the passing signals of the corrugated paper piece 1a detected at each detection position. The arithmetic unit 23 is an output terminal.

による。Incidentally, if at least two acoustic detection pickups 14 are arranged in the width direction of the running corrugated paper piece 1a, that is, the direction CP-P line that is substantially perpendicular to the running direction, the diagonal running property of the corrugated paper piece 1a can be detected. . The reason why the pickups are arranged almost at right angles is that even if they are not arranged at right angles, if the amount of deviation of the installation position from the pp line is known, corrective calculations can be made in the signal processing section later. Depends on something.
次に本実施例による検出装置の作用を説明する。Next, the operation of the detection device according to this embodiment will be explained.

The ultrasonic wave transmitted from the wave transmitter 14-1 is reflected by the corrugated paper piece 1a and is not transmitted, so the wave receiver 14-2 does not receive the ultrasonic wave. In the same figure) is (c)
This is the state after the corrugated paper piece 1a has passed from the state shown in FIG. The transmitted ultrasonic wave is transferred to the delivery device 1 because there are no obstacles in the way.

This is the output waveform of the switch signal from 4 through the amplifier 20. When the corrugated paper piece 1a runs diagonally, as shown in FIG.
The timing of switching to F is shifted, and the time difference △t1, Δt,
occurs. This time difference corresponds to the amount of inclination of the corrugated paper piece 1a, and the amount of inclination tanθ (inclination angle θ) is
Obtained at t7B. However, ■ is the traveling speed of the corrugated paper piece and is received from the feeding speed signal transmitter 21. Δt is the time difference detected by any two acoustic detection pickups, and B is the installation position interval of the two acoustic detection pickups. When the above calculation formula is executed by the calculator 22, the attitude of the corrugated cardboard piece 1a, that is, the state of diagonal running is recognized, and an output signal can be taken out at the output terminal 23.
