BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a maintenance machine for a packaging machine according to an embodiment of the present invention will be described with reference to the accompanying drawings, taking a liquid filling packaging machine as an example.

Referring to FIG. 1, the entire structure of the filling and packaging machine will be described. The filling and packaging machine is provided with a holding frame 1, and an original film 1A in which a film 2 for packaging is wound around a roll on the holding frame 1. Is provided so as to be removable. Also,
In the filling and packaging machine, a film guide mechanism 3 and a film folding mechanism 4 are provided for hermetically packing the material to be filled (material to be packed) W, and a vertical sealing mechanism 5 and a horizontal sealing mechanism (heat sealing mechanism) 6 are provided. , A filling mechanism 7 and a cutting mechanism 8.

The film 2 is made of a laminate of nylon and low-density polyethylene having a portion corresponding to a seal portion, which will be described later, and is pulled out from the roll-shaped raw film 1A by a vertical seal mechanism 5 serving as a mechanism for feeding the film 2. ,
The film 2 is led out to the film folding mechanism 4 via the film guiding mechanism 3, and the film 2 is folded in two along the longitudinal direction by the folding guide provided in the film folding mechanism 4.

The vertical sealing mechanism 5 is rotatably provided by the driving means M1, and is folded in half by a vertical sealing plate 5B provided along the outer circumference of a pair of opposed vertical heat sealing rolls 5A. Each of the folded edges and the folded ends (both right and left edges) is heat-sealed in the vertical direction while being fed out to form a vertical seal portion 2A. In addition, inside both vertical heat seal rolls 5A,
An electric heater for warming the vertical seal plate 5B is incorporated.

The horizontal sealing mechanism 6 is rotatably provided by the driving means M2, and the film 2 is heat-sealed in the horizontal direction by a horizontal sealing plate 6B provided on a pair of horizontal heat sealing rolls 6A opposed to each other. The bottom part which becomes the bag P, that is, the horizontal seal part 2B is formed. In addition, an electric heater is built in both horizontal heat seal rolls 6 </ b> A, similarly to the vertical seal mechanism 5. Further, the horizontal seal mechanism 6 is provided with a rotation detecting means (detecting means) 6C for detecting the rotational position of the horizontal heat seal roll 6A.

The filling mechanism 7 is composed of a seasoning or soup containing solids such as sesame and meat pieces in the film 2 formed into a continuous bottomed cylindrical shape by the vertical seal portion 2A and the horizontal seal portion 2B. The object to be filled W is filled. Further, the mouth portion of the film 2 containing the material W to be filled is further fed and heat-sealed again by the horizontal sealing mechanism 6 in the horizontal direction to be in a sealed state.

The cutting mechanism 8 cuts and cuts a substantially central portion of the horizontal seal portion 2B of the film 2 which is continuously wrapped in the up-down direction by a pair of opposed blades (not shown), and cuts the packaging bag P by 1 each. It is to separate them one by one. Further, the cutting mechanism 8 has a photoelectric sensor that responds to each cutting operation of the blade, and is provided with a production number counter for counting the number of produced packaging bags P.

Next, the electrical configuration of the filling and packaging machine of the present invention will be described with reference to FIG.

The rotation detecting means 6C comprises a proximity sensor. In this case, the rotation detecting means 6C is provided so as to be able to detect a detecting portion such as a dog provided on the horizontal heat seal roll 6A of the horizontal seal mechanism 6, and the horizontal heat seal roll 6A 4 per rotation
It generates a pulse signal and outputs this signal as an output signal to control means described later.

The setting means K1 comprises a touch panel,
A maintenance time corresponding to the durability of each component constituting each mechanism is provided so as to be input and set as data. For example, a set value such as a durable number of rotation of 100 million times of a bearing (not shown) that supports the horizontal heat seal roll 6 </ b> A and a durable number of driving of a cutter blade (not shown) of 10 million times is input as data.

The control means (counting means) K2 is composed of, for example, a microcomputer, and includes a ROM for storing a program for processing operations to be described later and various set values (for example, set values input by the setting means K1). It has a RAM for temporarily storing values, a CPU for executing the program, an internal timer, and the like, and an electrical control for controlling various signals from the circuit detecting means 6C and the setting means K1 and a notifying means to be described later. It has an I / O interface that makes a simple connection. The control means K2
Can also be used as control means for electrically controlling the filling and packaging machine.

The notifying means K3 comprises a touch panel and an alarm buzzer which are also used as the setting means K1.
Based on the control signal output from 2, the display on the touch panel and the sounding of the alarm buzzer are performed to notify the worker of the state of the packaging machine.

Next, the processing operation of the control means K2 will be described with reference to FIG.

The control means K2 inputs data of a count value set in advance by an operator's input operation in the setting means K1 (step S1). In this case, an example will be described in which, when the horizontal heat seal roll has rotated 100 million as the set value N, the operator is notified of the replacement time of the bearing that supports the horizontal heat seal roll 6A.

Next, the control means K2 includes a rotation detecting means 6C.
Is monitored (step S2), and the count value C is counted by the internal counter every time the horizontal heat seal roll 6A makes one rotation, that is, every time four pulses are input (step S3).

Next, the control means K2 calculates the count value C and the set value N
(Step S4), and when it is determined that the count value C is equal to or greater than the set value N, a control signal is output to the notifying means K3, and the notifying means K3 is operated, so that the worker is notified of the set value target component. Is displayed and a warning is issued to prompt the maintenance of the bearing (step S5). The notification means K
It is inconvenient that the display of the touch panel or the alarm buzzer sounds for a long time is inconvenient. Therefore, the display is returned to the normal display after a lapse of a predetermined time, and a mark indicating a message is displayed on a required portion of the touch panel. It is desirable to keep.

After replacing the bearing in response to the above-mentioned display and alarm, or after replacing the bearing due to damage of parts due to an accident that may occur normally, the operator uses the touch panel to read the count value C on the touch panel. A reset operation can be performed. Therefore, the control means K2 determines whether or not a reset operation has been performed (step S6), and if the reset operation has been performed, resets the count value C to "0" (step S7).

By repeating the above-described steps S1 to S7, the horizontal heat seal roll 6A
When the count value C becomes equal to or more than the set value N, the maintenance time of the bearing can be notified to the operator.

The number of rotations of the horizontal heat seal roll 6A is also limited to components (eg, a timing belt, an air cylinder, a solenoid valve, and a seal plate) other than the bearings that operate with the rotation of the horizontal heat seal roll 6A. A rotation detecting means 6C for detecting (number of times of driving) and a control means K2 which receives an output signal from the rotation detecting means 6C and counts according to the number of rotations of the horizontal heat seal roll 6A.
And a notifying means K3 for notifying the maintenance time of each component linked with the horizontal heat seal roll 6A when the count of the control means K2 reaches a predetermined value corresponding to the durability of the component. Accordingly, it is possible to notify the worker of the maintenance time of the component parts by the same processing procedure as that shown in the above-described embodiment of the present invention, and it is possible to perform maintenance management on a plurality of component parts simultaneously. You can also.

Further, the provision of the setting means K1 capable of inputting the count value C corresponding to the maintenance time of each component makes it possible to change the maintenance time for each component having different durability. Further, it is possible to select an empirical set value N by the operator or a set value N according to the operating environment of the packaging machine such as temperature and humidity.

In the embodiment of the present invention, the maintenance of the components such as the bearings is shown using the rotation detecting means 6C. However, the present invention is not limited to this. It is also possible to maintain and manage the driving means M1 and M2 and the components operating in synchronization with the driving means M1 and M2. In this case, the output is output from the driving means M1 and M2 via the driving circuit. The control means inputs an encoder signal (encoder pulse), and the number of rotations of the drive means M1 and M2 is determined based on the encoder signal (count of the drive circuit), and the count value is counted according to the number of rotations. Thus, maintenance and management can be performed in the same manner as in the above-described embodiment. Further, by counting the number of times of driving of the component parts interlocked with the driving means M1 and M2, each component part can be maintained and managed.

In the present invention, input means (not shown) for a control means K2 such as a safety switch provided on an opening / closing door of a packaging machine or an operation confirmation sensor provided on a cylinder is a component, and serves as a counting means. The control means K2 inputs the ON / OFF switching signal from the safety switch and counts the number of ON / OFF switching times, so that the operator can be notified of the maintenance time of the safety switch.

Further, in the present invention, an output means (not shown) for a control means K2 such as a relay for switching on / off a solenoid valve for driving a cylinder provided in the packaging machine is constituted as a component, and the control means K2 comprises By counting the number of times the command signal for switching the relay on / off is output, the maintenance time of the relay corresponding to the number of on / off switching or the solenoid valve operating in conjunction with the on / off switching is provided to the operator. I can let you know.

The control means K2 receives count data (output signal) of a production number counter provided in the cutting mechanism 8, determines the number of times of driving of each component according to the count data, and performs maintenance work. Can also inform others. In this case, since the count value corresponding to the number of times of the cutting operation can be counted, it is possible to inform the blade of the cutting mechanism 8 of an accurate maintenance time.

Further, in the embodiment of the present invention, the detection result of the drive state of the component by the detection means is inputted to the control means, and the worker is provided with the configuration in accordance with the result of counting the number of times of driving of the component by the control means. Although the notification of the maintenance time of the parts has been described, the signal from the detection means is taken into the integration counter (counting means) without passing through the control means to count the number of times of driving, and the integration counter notifies the notification means according to the count result. May be driven.

In the embodiment of the present invention, the setting means K1 sets the set value N in the number of times of driving of each component, and the control means K2 serving as the counting means receives the output signal from the detecting means 6C. Although an example of counting the number of times of driving a predetermined component has been described, the present invention is not limited to this. For example, "when 100 million packaging bags are produced, a maintenance time is notified". The maintenance may be performed using a set value and a count value obtained by converting the number of times of driving as the number of products produced by the setting method.

In addition, according to the driving method and characteristics of each component, as described in Japanese Patent Publication No. 8-5470, the integrated time of the main power supply and the driving operation time are calculated. It is also conceivable to combine this with a notification of the maintenance time.
