Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention automatically conveys glassware molded by a specific section of a glassware molding machine with legs used for molding glass cups with legs, cups with bases, etc. The present invention relates to a section discharge device of a glassware molding machine with legs that can be discharged from above.

The above-mentioned glassware forming machine with legs blow-molds a thin-walled glass container by a multi-section blowing machine, and supplies this in an inverted state to a press machine having the same number of sections as the blowing machine. It is a molding machine that inserts a gob into the upper surface to press-form the legs (base) and at the same time joins to the container.

By the way, if a mold is replaced in a specific section of a blowing machine or a press machine of the glassware molding machine with legs, the mold immediately after the replacement has a low temperature and causes a problem called mold cooling. It is necessary to remove the glassware molded in that section from. For this reason, conventionally, the operator visually confirmed the glassware molded in that section and removed the glassware with scissors, but if the molding speed is high, many glassware must be eliminated. However, there is a problem that the glassware to be removed accidentally flows to the subsequent process.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and when mold cooling or other trouble occurs in a specific section of a glassware molding machine with a leg, molding is performed in that section. The present invention has been completed to provide a section discharge device for a glassware forming machine with a leg, which can automatically discharge the glassware with a leg from a conveyor.

[0005]

[Means for Solving the Problems] The above-mentioned problem is to supply a container part formed by a multi-section blowing machine to a press machine having the same number of sections to manufacture a glassware with legs. And a section number reading means for reading the timing when each section of the rotary table type press machine passes the origin, a discharge command switch installed corresponding to each section, and this discharge command A gate circuit that issues a discharge signal when a section designated by a switch passes a predetermined position, a delay circuit that delays the discharge signal, and a discharge means that discharges the glassware from the conveyor at the timing set by the delay circuit. By the section discharge device of the glassware molding machine with legs, which is characterized by It is possible to attain.

[0006]

The present invention will be described in more detail below with reference to the illustrated embodiments. In FIG. 1, reference numeral 1 denotes a rotary multi-section blowing machine, and in the embodiment, 16 sections 2 provided with a blowing mold are arranged at equal intervals. A gob is supplied to the blowing machine 1 at a position indicated by an arrow 3, and a thin container portion is formed by a known method. The formed container portion is taken out to the transfer conveyor 5 by the take-out device 4, and is supplied to the rotary table type press machine 7 by the supplying device 6. The press machine 7 has the same number of sections 8 as the blowing machine 1.
, And the gob is supplied at the position of the arrow 9 to press-mold the glassware with legs.

The blowing machine 1, the take-out device 4, the transfer conveyor 5, the feeding device 6, and the press machine 7 are all operating at the same timing in synchronization with the gob feeder, and the number of sections of the blowing machine 1 and the press machine 7 is the same. Are the same, so by synchronizing the container part formed in the first section of the blowing machine 1 to feed the first section of the pressing machine 7, in the present invention the section number of the pressing machine 7 and the blowing machine 1 are synchronized. Section numbers can be treated as a common number.

Reference numeral 10 is a drive device for intermittently rotating the rotary table type press machine 7, and an index signal corresponding to the rotation of the press machine 7 can be taken out by a rotary encoder 10a connected thereto. Further, a table origin reading means 11 is provided on the side of the rotary table of the press machine 7, and the rotary encoder 10a and the table origin reading means 11 constitute a section number reading means. In the embodiment, the table origin reading means 11 is a proximity switch, and by detecting the iron block 11a attached to the first section of the press machine 7, it is possible to read the timing when the first section passes the origin. The index signal from the rotary encoder 10a and the signal from the table origin reading means 11 are input to the section reading circuit 12 to identify the section number passing through the origin.

On the other hand, a discharge command switch 13 corresponding to each section number is provided in a switch box provided on the side of the molding machine. When a trouble occurs in the blowing machine 1 or the press machine 7, the operator selects the discharge command switch 13 corresponding to the section number.
Turning on indicates that the glassware molded in that numbered section should be excluded. In the embodiment, the discharge command is continued until the discharge command switch 13 is manually turned off.

Reference numeral 14 is a gate circuit. This gate circuit 14
A signal from the section reading circuit 12 and a discharge command signal from the discharge command switch 13 are input to the. When the section 8 corresponding to the discharge command signal has passed the predetermined position (origin in this case), the gate circuit 14 issues a discharge signal.

Reference numeral 15 is a delay circuit. This is a circuit for delaying the discharge signal output from the gate circuit 14 in accordance with the operating speed of the molding machine or the conveyor. That is, the discharge signal is issued at the moment when the section passes the predetermined position, but there is a time delay until the glassware molded in the section reaches the discharge means 17 provided on the conveyor 16, so that the delay circuit is provided. 15 delays the ejection signal by this time. The index signal from the rotary encoder 10a is input to the delay circuit 15.

[0012]

The section discharge device of the present invention thus constructed is used when some trouble occurs in a specific section of the blowing machine 1 or the press machine 7, and the operator issues a discharge command for the section number. When the switch 13 is turned on, the section number reading means detects that the designated section has passed a predetermined position, and at the same time, the gate circuit 14 outputs an ejection signal.

The discharge signal thus generated from the gate circuit 14 is delayed by the delay circuit 15 and is removed from the conveyor 16 at the moment when the glassware molded in that section passes in front of the discharge means 17. To do. In this embodiment, the discharge is continued until the discharge command switch 13 is returned by the operator, but the discharge command switch 13 may be automatically reset after a predetermined number of glassware are discharged by incorporating a counter. it can. It is also possible to direct the discharge of all sections.

[0014]

As described above in detail, according to the present invention, when a trouble occurs in a specific section of the blowing machine or the press machine of the glassware molding machine with legs, the switch operation is simply performed. Glassware molded in sections can be automatically eliminated in succession. Further, according to the present invention, by making the section numbers of the blowing machine and the press machine the same, defective molded products in the blowing machine can be reliably discharged from the conveyor. Therefore, the present invention is extremely large in that it contributes to the industrial development as a section discharge device of a glassware molding machine with legs, which solves the conventional problems.
