Description

The present invention relates to a bottle capping machine having a centralized monitoring device for production management.

[Conventional technology]

FIG. 8 shows a plan layout of a conventional bottle filling machine.

The bottle 22 sent by the bottle conveyor 1 is indexed by the screw 2 and sent to the filling section 4 by the inlet starwheel 3 to be bottled. Bottled bottle22
Is transferred to the tapping machine 7 by the transfer starwheel 5 and is plugged, and is discharged to the outlet starwheel 8 and to the discharge conveyor 11. Here, the product liquid such as beer dissolves carbon dioxide in the liquid, and the filling liquid is filled under pressure. A bottle having a low strength due to damage or the like sometimes breaks at the time of filling, and the tapping portion 7 also breaks. Therefore, in order to count the number of products, the number of bottles is counted by the detector G in the bottle supply unit 1 and the number of products is counted by the detector H in the discharge unit 11, so that the number of bottles is calculated by the counting unit 21. The number of products and the number of broken bottles (total of filling parts and stopper parts) are displayed separately. However, no indication is given for the cause of the rupture.

Also, since products such as beer do not like the air above the bottle mouth, a jet forma 6 is installed on the transfer star wheel 5 part,
Jet water is injected into the bottle, and bubbles (CO ₂ gas) generated by agitation are used to expel the air in the head space and then plugged. Therefore, in order to make the timing at which bubbles overflow from the bottle opening up to the tapping position, the position of the jet former 6 is structured to be rotatable with respect to the center of the transfer star wheel, and the operator sets the optimum position.

[Problems to be solved by the invention]

 The prior art as described above has the following problems.

(1) Only the number of products and defective products can be displayed, but no indication of causes such as rupture can be made.

(2) The operator sets the jetting position of the jet forma, cannot respond to the foaming change of the product and cannot detect the abnormal state automatically, and the operator constantly monitors the operating state of the line. Needed.

(3) Since bottles that could be defective products were not detected at each location, automatic rejection of defective products could not be performed, and a separate device with a product inspection function was installed as a bottle filling line. I needed to.

The present invention provides (a) a bottle capping machine that detects the condition of a product and performs accurate tabulation to enable effective production control. (B) A part that is abnormal (defective) as a product At the same time as detecting, reject defective products. (C)
The purpose is to provide a bottling machine that can monitor the entire bottling plant and make it unmanned.

[Means for solving the problem]

As shown in FIGS. 1 to 7, (1) Install a detector A for detecting the presence / absence of a bottle in a bottle filling portion.

(2) Install a detector B that detects the presence or absence of a rupture in the bottle filling part.

(3) Install a detector C to detect the presence or absence of bubbling up to the upper surface of the bottle opening before tapping.

(4) Install a defective bottle detector D that detects broken bottles and defective filling.

(5) Install a detector E to determine whether the crown is plugged.

(6) Install a detector F that detects a normal product.

(7) Install a detector G that detects the presence or absence of a vent tube for normal filling.

(8) The abnormal product in the above (3), (4), and (5) is discharged to the reject conveyor (12) by the reject star wheel 10, and a detector F for detecting only non-defective products is installed.

(9) A centralized monitoring system is configured in which the detection signals at the respective sections described in the above items (1) to (8) are input to the control section, and are arranged and displayed in desired production management information.

(Operation)

The number of the following items can be grasped from the supply of the production bottle and each detector.

Number of bottles supplied: Number of detectors A Number of products: Number of detectors F Total number of defectives: (Counts of detector A-counts of detector F) Breakdown of defectives Number: Detector A count number-Detector B count number Insufficient jetformer number: Detector C count number Bad taste number: Detector D count number Defective plugging number: Detector E count number Detector D above Is counted as a value obtained by subtracting the count B of the detector B from the count A of the detector A and the number x of defective bottles that cannot be checked by the detector in the plugging process. When this is represented by an equation, A− (B + x) = D. From this equation, the number x of defective bottles that cannot be checked by the detector in the plugging process is x = A
−BD can be calculated.

The detector G can detect the fall of the vent tube and can detect an abnormality in the equipment.

If the continuous occurrence of C, the continuous occurrence of D, and the continuous occurrence of E (each of about 5 to 10 times) are detected, it can be found as an abnormality of the equipment.

It is a crown.

FIG. 1 shows a plan layout and a detector layout of the bottle filling machine of the present invention.

Bottle 22 is sent by bottle conveyor 1 and screw 2
And sent to the filling unit 4 by the inlet starwheel 3. In the filling section 4, as shown in FIG. 2, the bottle 22 is brought into close contact with a filling valve 23 by a lifter 21 and then filled by a known method. Here, the detector A for detecting the presence or absence of the bottle 22 directly detects the bottle 22 as shown in FIG.
Detect the difference by the dimension, or in any way,
It is detected whether the bottle 22 has been sent to the filling section 4.

Next, a beverage containing CO _{2 in} a liquid such as beer is filled under pressure in order to prevent separation of CO ₂ from the liquid. However, when filling under this pressurization, a bottle with a low strength may be broken due to damage or the like. Therefore, it is necessary to directly detect the bottle with the detector B (as shown in Fig. 3 even though there is a signal at A). In the case of B, no signal is output), or the occurrence of a difference in the S dimension in the height of the lifter 21 is detected. The bottle 22 filled in the filling section 4 is sent to the transfer star wheel 5, and the cap 26 is plugged by the tapping machine 7,
It is sent to the exit star wheel 8. Here, it is known that a product such as beer which dislikes air in the upper space of the bottle mouth (head space air) a is provided with a jet former 6 shown in FIG. I have. This is to inject jet water into the bottle, and to bleed the bubbles generated by the separation of CO ₂ dissolved in the liquid up to the bottle mouth, to expel the air in the head space a, and to reliably expel the air. Is important for product quality. The position of the stopper is fixed, so that the jet forma 6 can be moved around the transfer star wheel 5 in order to ensure that the air is expelled. Whether or not the air in the head space a is expelled is determined by detecting the presence or absence of the space dimension t on the crown 26 and the upper surface of the bottle by the detector C as shown in FIG.

The exit starwheel 8 exits and the reject starwheel 22 is synchronized with the screw 9 at the timing 9
Sent to 10. In this screw 9, as shown in FIG. 7, a detector D for detecting whether or not the filling amount is normal, and a crown presence / absence detector E for seeing whether or not the crown 26 is plugged are provided. , About the abnormal thing in the detector C, D, E, it is held by the reject star wheel 10,
It is discharged to the reject conveyor 12. The reject star wheel 10 is a star wheel having a known air chuck and having a pocket for grasping the bottle 22 by a signal. The normal bottle 22 is discharged to the discharge conveyor 11, and the detector F detects the number of bottles as a count signal.

At the non-filling portion between the inlet starwheel 3 and the transfer starwheel 5, as shown in FIG. 4, a detection for detecting whether or not the vent tube 25 for determining the filling line of the filling valve is properly dispatched. Vessel G is installed. The detection signals of these detectors A, B, C, D, E, F, and G are input to the control unit 20, and are arranged and displayed as information necessary as production means. The following can be displayed as display examples.

(1) Number of supply bottles (Detection A) (2) Number of products (Detection F) (3) Total number of defective units (Detection A-F) (4) Breakdown of defective units Number of filled bottles (Detection A-B) Number of defective bottles (detection C) Number of defective bottles (detection D) Number of defective plugs (without crown) (detection E) The number x of defective bottles that cannot be checked by the detector in the plugging process is calculated by A− (B + x) = D. .

In addition, the machine can be stopped by an input signal from the detector G and a continuous abnormal signal (about 10 times) from the detectors C, D, and E as a machine abnormality.

Although not shown in FIG. 1, the production efficiency can be calculated by inputting information on the amount of liquid and the amount of crown required for the bottle capping machine.

Further, in FIG. 1, the synchronization timing to the reject star wheel 10 is implemented by the screw 9. However, the same function can be achieved by a structure in which a star wheel is provided to take synchronization timing.
