2. Description of the Related Art Packaging machines and bundling machines handle, for example, a large bundle of many newspapers as one packaging unit and a small bundle of a small number of newspapers as one packaging unit.

[0003] Each of the objects to be packaged is subjected to film packaging by driving of a packaging machine and then bound by a band or the like together with the packaging film by driving of a binding machine. Conventionally, the driving of the wrapping machine and the driving of the tying machine are performed by inputting separate start and stop command signals from the centralized control panel to the wrapping machine operation panel and the tying machine operation panel. And in the binding machine, individual start and stop were performed based on this command signal.

[0004]

However, the above-mentioned conventional packaging machine and binding machine which individually receive command signals from the centralized control panel are provided with the installation of the centralized control panel, the packaging machine and the binding machine from the centralized control panel. Since each wiring to the binding machine is large, there is a problem that the equipment cost increases.

According to the present invention, in view of such conventional circumstances, the starting operation and the stopping operation of the packaging machine are interlocked with the starting operation and the stopping operation of the binding machine. The purpose of the present invention is to provide an interlocking control device.

According to the present invention, there is provided an interlocking control device for starting and stopping in a packaging machine and a connecting machine, in which start and stop signals for starting and stopping a packaging machine for film packaging an object to be packaged are input, respectively. When the start and stop signals are input respectively,
A wrapping machine remote start / stop input circuit that outputs start and stop signals to the wrapping machine, respectively, and the wrapping machine is provided continuously with the wrapping machine so that the objects to be wrapped with the film wrapped by the wrapping machine are bound by a band or the like. Start and stop signals for starting and stopping the tied binding machine are respectively inputted. When the start and stop signals are inputted, respectively, the start and stop signals are given to the tying machine. The bundling machine remote start / stop input circuit and the packaging machine start / stop signal output from the packaging machine remote start / stop input circuit are converted into the binding machine start / stop signal, respectively, to convert the bundling machine remote start / stop input circuit. And an interlocking start / stop output circuit that outputs the start / stop signal.

[0007]

The wrapping machine is started and stopped by a wrapping machine remote start / stop input circuit, and the start / stop operation is pulse-converted into a start signal and a stop signal by an interlocking start / stop output circuit, respectively. .

When the start signal and the stop signal are input to the binding machine remote start / stop input circuit, the binding machine performs a start operation and a stop operation in conjunction with the packaging machine.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

The interlocking control device 1 shown in FIGS.
The packaging machine remote start / stop input circuit 2, the packaging machine-side interlocking start / stop output circuit 3, and the binding machine remote start / stop input circuit 4 are mainly configured. Reference numeral 5 denotes a binding machine-side linked start / stop output circuit, which is provided in the binding machine remote start / stop input circuit 4 when the starting operation and the stopping operation of the binding machine are linked to downstream devices.

That is, the interlocking control device 1 includes a packaging machine remote start / stop input circuit (hereinafter referred to as a packaging machine input circuit) 2.
A wrapping machine-side interlocking start / stop output circuit (hereinafter referred to as a wrapping machine-side interlocking output circuit) 3 for converting the opening / closing operation of the wrapping machine input circuit 2 into a start signal D and a stop signal J described later.
The packaging machine side interlocking output circuit 3 is provided with a binding machine remote start / stop input circuit (hereinafter referred to as a binding machine input circuit) 4.
Is connected to the

The wrapping machine input circuit 2 allows the wrapping machine to be started by selecting one of the operation switch S1 of the operation panel and the start button PB1, while the wrapping machine is stopped by the operation switch S1 and the stop button. It is configured to select any one of PB2.

For example, when the start button PB1 is turned on, the start relay R1 is energized and its contacts are turned on to start the packing machine B. When the stop button PB2 is turned on G, the stop auxiliary relay R2 and the stop relay R3 are excited, and the respective contacts are turned off, so that the packaging machine is stopped H.

The wrapping machine-side interlocking output circuit 3 converts the starting operation and the stopping operation of the wrapping machine into pulse signals C and I to link the wrapping machine input circuit 4 with the contact of the starting relay R1. The activation signal relay R
4 and the activation pulse timer T1, for example, the pulse conversion C is performed on the activation signal D having a pulse width of 0.1 second. At the same time as the contact of the stop relay R3 is turned off, the stop signal relay R5 and the stop pulse timer T2 perform pulse conversion I to a stop signal J having a pulse width of 0.1 second, for example. .

As in the case of the packaging machine input circuit 2, the binding machine input circuit 4 activates the binding machine independently by operating the switch S11.
And the start button PB11 is selected, and the start signal D from the wrapping machine side interlocking output circuit 3 is input to the start relay R11, so that the binding machine starts the wrapping machine. It is designed to start in conjunction with the operation. The single stop of the binding machine is enabled by selecting either the operation switch S11 or the stop button PB12, while the stop signal J from the packaging machine side interlocking output circuit 3 is input to the stop auxiliary relay R12. By performing K, the binding machine is stopped in conjunction with the stopping operation of the packaging machine. However, during the binding operation L of the binding machine, even if the contact of the stop auxiliary relay R12 is switched to the OFF state, the contact of the activation relay R11 is maintained in the ON state and the binding operation is connected, and the completion of the binding operation L is completed. Sometimes, when the contact of the start relay R11 is switched to the off state, the contact of the stop relay R13 is also switched to the off state, and the binding machine is stopped M.

As in the case of the packaging machine-side interlocking output circuit 3, the binding machine-side interlocking start / stop output circuit 5 controls the start-up operation and the stop operation of the binding machine by a start signal relay R14, a start pulse timer T11, a stop signal relay R15, A circuit that is converted into a start signal and a stop signal by a stop pulse timer T12. The start signal and the stop signal are input to a remote start / stop input circuit of the downstream device, so that the start operation and the stop operation of the downstream device are performed. The start and stop operations of the binding machine can be linked.

Further, by inputting a start signal X of the upstream device to the start relay R1 of the packaging machine input circuit 2 and a stop signal Y of the upstream device to the stop auxiliary relay R2, the start of the packaging machine is started. The operation and the stop operation can be linked with the start operation and the stop operation of the upstream device.

Next, the operation of the above embodiment will be described.

In FIG. 3, the packaging machine has a start button PB
In the ON operation A of 1, the activation relay R1 performs the ON operation and is activated B. In the ON operation of the activation relay R1, a pulse conversion C is performed on the activation signal D by the activation pulse timer T1 and the activation signal relay R4.

The start signal D is used as the start relay R1 of the binding machine.
When the start relay R11 is turned on when the input E is input to 1, the binding machine starts the start F in conjunction with the start operation of the packaging machine.
Is done.

On the other hand, when the stop button PB2 is turned on F, the stop auxiliary relay R2 and the stop relay R3 are turned off to stop the packaging machine. The turning-off operation of the stop relay R3 is performed by the stop pulse timer T2 and the stop signal relay R5.
The pulse conversion I is performed on the stop signal J.

When the stop signal J is input to the auxiliary stop relay R12 of the binding machine, if the binding machine is in the operation of binding L, the stop relay R13 of the binding machine is not activated and the binding of the binding machine is not performed. When the operation is continued and the binding operation is completed, the start relay R11 and the stop relay R13 are switched to the off state, and the binding machine is stopped M.
