Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic jam detecting device for a multi-row transport container on a conveyor device such as a food machine.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 8, a lever 1 is used to detect a bottle clogging on a multi-row line in a bottle filling line.
01 and the proximity switch 102 detect the presence or absence of the bottle 100, and the impeller 103, the proximity switch 104 and the motion detector 105 incorporated in the lever 101 detect the bottle 1
The motion of 00 was detected. The controller 106 outputs the output of the proximity switch 102 and the motion detector 105.
When the output of the proximity switch 102 is output, the output of the motion detector 105 is checked, and when there is no output, it is determined that the bottle 100 is congested and the upstream device is controlled.

The reason why such a system is adopted is that when the presence / absence of a bottle is detected and the upstream device is controlled, the absence of the bottle cannot be detected until the bottle has completely flowed, and the restart of the upstream device is delayed. .. Therefore, even if there is a bottle, if the bottle moves, the bottle is still flowing, so the motion detector method was adopted. Further, in the case of a multi-row line, since the bottle interval is narrow, it is difficult to mount the sensor on the bottle side. Therefore, the presence / absence of a bottle is detected from above via a lever.

[0004]

As described above, in the prior art, a lever 101 for detecting the presence / absence of the bottle 100 and an impeller 1 for detecting the movement of the bottle 100 have been used as a bottle congestion detecting device in a multi-row line.
Since 03 was used, it was not suitable for a line whose speed was faster than the response of lever 101. Also, since the bottle guide width is set roughly on the multi-product line,
The flow of the bottle 100 varies in the width direction, and the lever 1
01 and impeller 103 did not always hit. Further, since it is composed of the lever 101 and the impeller 103, the structure is complicated and much time is required for maintenance.
The present invention has been proposed to solve the above conventional problems.

[0005]

Therefore, according to the present invention, there is provided a fiber type sensor which is embedded in a guide for partitioning a transfer line of a multi-row container to detect the presence or absence of the container, and a side portion of the head position of the container to be transferred. A head detection sensor connected to the motion detector corresponding to each row and detecting the movement of the container head, a container “present” signal from the fiber type sensor, and a signal from the motion detector. A control device to which a flow signal is input is provided, and the congestion state of the container is determined according to the signal from the motion detector input to the control device. To do.

[0006]

[Function] Since a fiber type sensor and a head detection sensor connected to a motion detector are provided to detect the presence / absence of a bottle and a head detection sensor that is connected to a motion detector, the guide width is wide and the flow in the width direction of the bottle is not constant in a multi-product line However, it is possible to reliably detect the congestion of bottles. In addition, responsiveness is improved, and maintenance is unnecessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments of the drawings. FIGS. 1 to 7 show an embodiment of the present invention, 1 is a conveyor frame, 2 is a conveyor chain, and 3-1 to 3-4 are FIG. In the embodiment of the present invention, bottles conveyed in four rows, 4 are bottle guides 5-1 to 5-5, and sensor brackets 6-1 to 6-.
With the bracket that fixes 4, the bottle guides 5-1 to 5-
5 is a frame 15-1 to 15-through a bracket 16.
It is supported by 2. 7-1 to 7-8 are fiber type photoelectric switches as fiber type sensors for detecting the presence / absence of a bottle, which are mounted on the groove 5a of the bottle guides 5-1 to 5-5 by mounting plates 9-1 to 9-8. ing. 8-1-8
-8 is a photoelectric switch as a head detecting sensor for detecting the movement of the bottle, which is attached to the sensor brackets 6-1 to 6-4. Also, photoelectric switches 8-1 to 8-8

30-4, and a power supply circuit 40.

Next, the operation of the embodiment constructed as described above will be described. First, bottle 3-1 is supplied from the upstream,
When the fiber type photoelectric switch 7-1 of the first column is shielded from light, the AND circuit 30-1 of the control device 11 is provided with "bottle".
A signal is input. The photoelectric switch 8-1 is also a bottle 3-
The head of No. 1 is shielded from light, and the bottle head “present” signal is input to the motion detector 10-1. When the bottles 3-1 are supplied one after another and the bottle head “present” signal (pulse signal) is input from the photoelectric switch 8-1 to the motion detector 10-1, a bottle flow signal is output from the motion detector 10-1 and control is performed. It is input to the NOT circuit 20-1 of the device 11. Since this signal is inverted by the NOT circuit 20-1, the AND circuit 30-1 is not established and the bottle congestion signal is not output.

Next, when the flow of the bottle 3-1 is congested due to the stop of the downstream equipment or the like, the bottle head "present" signal is interrupted, and the bottle flow signal is not output from the motion detector 10-1. Therefore, a signal is output from the NOT circuit 20-1,
The AND circuit 30-1 is established and a bottle traffic jam signal is output. Although the first column has been described above, the same applies to the second to fourth columns.

[0010]

As described above in detail, according to the present invention, in the detection of bottle congestion on a multi-row line, even if the guide width is wide and the flow in the width direction of the bottle is not constant in a multi-product line, a reliable spread can be achieved. Traffic congestion can be detected. In addition, responsiveness is improved, and maintenance is unnecessary.
