BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a multi-head type covering apparatus according to the present invention.
In FIGS. 1 to 3 and 5, A is a multi-head type covering device used in the fluid filling and packaging industry, in which each moving means 1 is provided with a plurality of winding means 2 serving as a plurality of heads. During the movement of the moving body 1, the cap c is applied to the mouth of the container b by screwing both male screws and female screws.

The moving body 1 is used for a rotary cover device as shown in FIGS. 1, 2 and 5, and a linear cover device as shown in FIG. Among these, the moving body 1 in the rotary-type covering device A is
The disk-like member is attached to a drive shaft 4 which is rotated at a predetermined speed, and as shown in FIG.

The container b is continuously supplied from the transfer line L to a table 6 attached to the drive shaft 4 via a rewinding means 5 such as a star wheel. It is taken out by the feeding means 7 such as a wheel and sent out to the transport line L.

The moving body 1 in the linear covering device A is a member that moves along an elevating guide 8 as shown in FIG. , And the containers b are supplied on a transport line L that moves in synchronization with the moving body 1.

The above-mentioned winding means 2 is provided with a conventional gripping member 10 of a mechanical type, a vacuum type, an air tube type or the like using a link, a wedge or the like on a rotating shaft 9 rotatably attached to the moving body 1. Thus, the cap c is appropriately gripped and released. A rotating means 11 such as a servomotor is linked to the rotating shaft 9, and rotation for cap tightening is given by a regulating means 12 described later so that a predetermined tightening torque is obtained.

In the case of the rotary cover device A, as shown in FIG. 1, the rotating shaft 9 can be moved up and down by a predetermined stroke by the elevating means 13 without obstructing its rotation. Further, as shown in FIGS. 2 and 5, the container b supplied from the feeding means 5 is supplied to the container A in a range R from the winding start position S to the winding end position E.
In step (c), the cap c is wound.

The restricting means 12 provides a predetermined tightening torque when tightening the cap c, and is provided for each of the tightening means 2. When the torque value set in advance is completed, A clutch or the like for releasing the rotation transmission is used, and this torque value can be arbitrarily adjusted by an adjusting member 14 such as an elastic machine or an air pressure.

The restricting means 12 includes a wireless transmitting means 17 comprising a winding detecting member 15 and a transmitting member 16.
Are connected, and among them, the winding detection member 15
Measures the change in strain resistance transmitted to the clutch by the regulating means 12 and outputs the data as a detected tightening value via the microprocessor system.

Further, the transmitting member 16 is
For example, the voltage reference signal and the current reference signal amplified in
Is transmitted as a signal of a unique radio frequency for each.

The receiving means 18 is configured as an antenna to receive a signal from the radio transmitting means 17 and is provided outside the moving body 1, that is, at a place where the moving body 1 does not receive the moving motion. Installed separately. In the case of the rotary cover device A, as shown in FIG. 2, the rotary cover device A is installed at a tightening end position E, or as shown in FIG. Installed in tightening section R. Similarly, in the case of the linear covering device A, as shown in FIG.
As shown by the imaginary line in FIG.

The signal received by the receiving means 18 is sent to the control means 19 and is displayed on a monitor or the like via a predetermined memory or an arithmetic circuit, and the operator is required to tighten the cap c applied to each container b. The state is grasped.

The radio transmitting means 17 and the receiving means described above can be of any type as long as they can transmit and receive information by radio, such as infrared rays and laser beams, in addition to radio waves.

Therefore, the multi-head type covering device A and the covering method of the embodiment of the present invention configured as described above are as follows.
The following effects are exhibited, and a case where the present invention is applied to a rotary lidding apparatus A will be described. The control means 19 includes
The reference value of the tightening torque of the cap c is input in advance. For example, as shown in FIG. 6, if the cap c is tightened with a torque that falls within the range of the appropriate torque value T, the container b It is determined that the applied cap c is properly tightened, and if data outside the range of the appropriate torque value T is received, it is determined that the improper tightening process is performed, and the transfer line L
Is more exhausted.

That is, the containers b are successively supplied from the transport line L via the feeding means 5 onto the table 6 of the multi-head type covering device A, and are stably held by a container gripper (not shown). On the other hand, the cap supply means 20
, The cap c is sent, and is held and held by the holding member 10 in the cover means 2.

With the rotation of the moving body 1, the winding start position S
The container b which has reached the opening is provided with rotating means 11 toward its mouth.
While being rotated by the operation of (1), the gripping member 10 is lowered by the operation of the lifting / lowering means 13, and the female screw of the cap c starts to screw into the external thread of the container b.

Then, in the regulating means 12, the winding detection member 15 of the wireless transmission means 17 associated with the clutch measures a change in strain resistance in the clutch.

Then, with the rotation of the moving body 1, the tightening of the cap c by the cover means 2 progresses, and when the winding means 2 reaches the tightening end position E, the transmitting member in the wireless transmitting means 17 is transmitted. When the control unit 19 determines that the signal received by the receiving unit 18 is data within the range of the appropriate torque value T, the closed container b is transported to the transport line L as it is, and is sent to the next step by the transport line L.

However, the wireless signal from the winding detection member 15 received by the receiving means 18
When it is determined that the data is out of the range of the appropriate torque value T, the so-called covered container b, which has been determined to be inadequately tightened, is taken out by the feeding means 7 and then attached to the transport line L. It is fed into the discharge means 23 outside the transport line L by the taken out means 22.

As shown in FIG. 5, the receiving means 18 is installed at predetermined plural places (not shown) continuously or at intervals from the winding start position S to the whole winding end position E. Then, the state in which the cap C is fastened by each of the fastening means 2 around the container b is instantaneously determined by a radio signal of a predetermined frequency emitted from the fastening detection member 15 for each time and section in which the fastening progresses and for each section. (In real time) because the receiving means 18 receives the signal, the winding section R
All the data for each section in are obtained.

In each of the above-mentioned winding means 2, the frequency of the radio signal transmitted from the transmitting member 16 in each of the radio transmitting means 17 is set to be a natural frequency (different frequency). The signal for each means 2 can be identified.

Therefore, it is monitored from the outside of the covering device A whether or not the tightening of one cap c has faithfully passed the basic pattern shown by the torque fluctuation waveform as shown in FIG. Even if it is the container b in which the specified torque is obtained in the final part of the tightening,
By not passing through the basic pattern described above, the winding itself is not easily understood by various visual inspections, such as when the cap c is improperly covered for other reasons, an abnormal tightening of the cap, or a defect of the cap c itself. Tightening can be detected. Also, by collating the received data with the basic pattern, it is possible to relatively easily find out and acquire the cause of the cause of the improper fastening due to the cause.

In particular, since the detection signal generated from the winding detection member 15 is sent to the receiving means 18 by radio, the rotary type covering device A does not require any complicated electric system connection means.

[0034]

According to the present invention constructed as described above, the restricting means for applying a predetermined tightening torque when the cap is tightened is connected to each of the tightening means, and these restricting means are connected to each other via the radio transmitting means. And a receiving means provided outside of the moving body, receives the detected tightening value, and based on the detected detected tightening value, determines the tightening of the cover. By performing the management, the rotational torque for tightening the cap is directly extracted as a signal as it is and converted into data, so that the attachment of the cap to the container is managed with high precision, and the tightening torque detected in the later process is not detected. The incidence of non-defective products can be greatly reduced.

The receiving means receives the detected value of the tightening between the position at which the tightening means starts and the position at which the tightening is completed in the movement of the moving body, so that the tightening is constantly performed during the tightening. Since the state data can be received, the tightening state can be checked and monitored while the tightening is in progress at an external position, and what is called a defective product outside the allowable range of the predetermined torque fluctuation waveform. Can be found instantaneously and can be immediately discharged from the transport line.

The structure is simple, and a modification to an existing covering device can be made. And so on.
