A control signal for controlling an injection molding machine that repeats the steps of mold clamping, injection, mold opening, and ejection in which the molded product held in the first mold is dropped from the top of the first mold in that order. Regarding the signal generation device for controlling the injection molding machine, in particular, the injection molding machine is used when a molded product or a partially missing piece thereof is held on the surface of the second mold,
A mold clamping control signal is output that can control the mold clamping process so that the mold clamping step is not performed in a state where the molded product is held without falling on the surface of the first mold.
The injection molding machine III trust signal generator is capable of controlling the injection molding machine in such a way that there is no fear that one or both of the first and second molds will be damaged.

[Conventional technology]

Conventionally, a first mold and a second mold are used which cooperate with each other, and the steps of mold clamping, injection and mold opening are sequentially performed in that order.
The molded product is obtained on the mold, and then the ejection process is performed, and the first
dropping the molded product held in it from above the mold,
An injection molding machine has been proposed that repeats the steps of mold clamping, injection, mold opening, and ejection in that order. FIGS. 1A, B, C, and D schematically show the steps of mold clamping, injection, mold opening, and ejection sequentially performed by such an injection molding machine (indicated by reference numeral 1). In the mold clamping process taken by the injection molding machine 1, Fig. 1A
As shown in the figure, a fixed mold 2A fixedly mounted on a fixed table 5A is a movable mold that can freely come into contact with and separate from the mold 2A fixedly mounted on a movable table 5B. A clamped state in which the molds 2B are in contact with each other is obtained. This state is obtained by driving the movable stand 5B on which the mold 2B is fixedly mounted by the mold clamping driving means 4. In addition, in the injection process taken by the injection molding machine 1, the first
As shown in FIG. B, in the above-described mold clamping state shown in FIG. and 2B, and a state is obtained in which the molded product 10 is injection molded between both molds 2A and 2B. Furthermore, in the mold opening process taken by the injection molding machine 1,
As shown in FIG. 1C, the mold 2B is driven by the above-mentioned mold clamping driving means 4, so that the injection molded product 10 is held on the mold 2B which is spaced apart from the mold 2A. This results in a state where In addition, in the protrusion step taken by injection molding R1, as shown in the first diagram, an ejection rod 12 that can move forward and backward into a guide hole 11 provided in the mold 2B is provided on a movable base 5B. By being driven by the driving means 14,
A state is obtained in which the molded product 10 held on the mold 2B is pushed down from above the mold 2B. The above-described injection molding machine 1 performs the above-described sequential steps of mold clamping, injection, mold opening, and ejection, and then re-clamping the mold,
When performing the sequential steps of injection, mold opening, and ejection, the mold clamping step in the latter sequential step is performed while the molded product 10 or a partially missing piece thereof is held on the surface GA of the mold 2A, The molded article 10 must not fall from the surface GB of the mold 2B and must not be taken while being held on the surface GB of the mold 2B. The reason is that if, in such a state, the injection molding machine 1 performs the mold clamping process in the sequential process of mold clamping again, injection, mold ejection, and ejection, the mold 2A will be held on the mold 2A. This is because there is a risk that one or both of the molds 2A and 2B may be damaged by the molded product or a partially missing piece thereof or the molded product 10 remaining on the mold 2B. For this reason, a signal generating device for controlling an injection molding machine has been proposed, which will be described below with reference to FIG. That is, during the period after the injection molding machine 1 sequentially performs the first mold clamping, injection, and mold opening steps until the first ejection step, the entire surface area of the mold 2B is G

The pre-ejection reference pattern information output means 348F can be inputted as the pre-ejection reference dancing image output ESF through the reference contacts S and the switch means 338F. Therefore, after the pre-ejection layer image output ESF in the period TSF-1 described above is input from the pre-ejection reference pattern information output means 343F, the pre-ejection reference pattern information ESF' is used as the reference pattern information for molded product holding area determination.

It is possible to output the information to the information output means 35SP. (c) As described above, after the pre-protrusion layer image output ESF is input to the pre-protrusion reference pattern information output means 348F during the period TSF-1 mentioned above, the pre-protrusion reference pattern information is output from the pre-protrusion reference pattern information output means 348F. ESF' can be output, and the above-mentioned period T

When the period from the mold clamping, injection, and mold opening processes (...) to the first ejection process is taken as TQF-i, in that period TQF-t , the changeover switch means 32 is switched to the working side contact Q side when obtaining a working molded product, and the switch means 33SF
, 33SA and 33QA are not opened, but if the switch means 33QF is opened and the imaging means 21 is operated in that state, the entire surface area GB of the mold 2B is covered with the molded product 10 by the imaging means 21 An image is taken while it is being held as a working molded product, and the image output is sent to the pre-ejection working pattern information output means 340F through the working side contact Q of the changeover switch means 32 and the switch means 330F.
can be inputted as the pre-ejection dynamic image output LQF. Therefore, the pre-projection operation pattern information output means 34QF outputs [
After the pre-ejection operation pattern output EQF is manually input, the pre-ejection operation pattern information EQF' can be outputted to the first mold clamping control signal output means 36C1. (E) As mentioned above, after the ejection process, the first mold clamping, injection, mold opening and ejection are performed. TSA-
After the ejected standard pattern information ESA' is manually input to the molded product holding area determination standard pattern information output means 35SP in 1, the molded product holding area determination standard pattern information is outputted from the molded product holding area determination standard pattern information output means 35SP. The information ESP' can be outputted to the first mold clamping control signal output means 36C1, and after the mold opening step in the sequential steps of first mold clamping, injection, mold opening, and ejection, After the pre-ejection layer image output EQF is input to the pre-ejection working pattern information output means 340F in the pre-process period T Q F-i, the pre-ejection working pattern information EQF' is inputted from the pre-ejection working pattern information output means 34QF.

During the period TQF-i until the mold is taken, the molded product 10 is held on the molded product holding area MB of the mold 2B as a working molded product equivalent to the reference molded product without any positional shift or missing part. means. In addition, when the molded product 10 is held on the molded product holding area MB of the mold 2B as a working molded product equivalent to a reference molded product without any positional shift or missing part, generally the mold 2
No odor or molded product 10 remains on the area MA corresponding to the molded product holding area MMB of the mold 2B of A, as well as in areas other than the area MA on the surface of the mold 2A. From the above, when the first mold clamping control signal EC1' is obtained with content that allows the injection molding machine 1 to perform the mold clamping process, the first mold clamping control signal EC1' The product 10 is held on the molded product holding area MB of the mold 2B as a working molded product equivalent to the reference molded product with no positional deviation and no missing parts, and the entire surface GA of the mold 2△
This indicates that no molded product 10 remains on the surface. Therefore, the ejection drive means 14 of the injection molding machine 1
When the mold clamping control signal EC1' is obtained with a content that allows the injection molding machine 1 to perform the mold clamping process, vJm is set so that the ejection process is not not performed, and Similarly, when the mold clamping drive means 4 of the injection molding machine 1 receives a first mold clamping control signal EC1' with a content that allows the injection molding machine 1 to take the mold clamping step. If the injection molding machine 1 has a configuration in which the mold clamping process is controlled so that the mold clamping process is not skipped, the first mold clamping control signal EC

It can be controlled to take the tightening process. No matter how the injection molding machine 1 is controlled in this way during the (i+1)th mold clamping process, in this case, no molded product 10 remains on the entire surface GA of the mold 2A. Therefore, the molded product 10 held in the molded product holding area MS of the mold 2B is not held at all from the entire surface GB of the mold 2B by the i-th ejection process of the injection molding machine 1. As long as they are protruded, one or both of molds 2A and 2B will not be damaged in the (i+1)th mold clamping step.

In QF-i, a state is obtained in which the molded product 10 is held on the molded product holding area MB of the mold 2B as a working molded product equivalent to the reference molded product with no positional shift and no missing parts. means that it cannot be In addition, the molded product 10 is not held in the molded product holding area MB of the mold 2B as a working molded product equivalent to the reference molded product without any displacement or missing parts. In the case, molded product holding area IIi of mold 2B of mold 2Δ
There is a possibility that the molded article 10 or a partially missing piece thereof remains on the area MA corresponding to tMB. From the above, when the first mold clamping control signal EC1' is obtained with content that prohibits the injection molding machine 1 from performing the mold clamping process, the first mold clamping control signal ECI' The condition that the product 10 is held on the molded product holding area MB of the mold 2B as a working molded product equivalent to the reference molded product without any positional shift or missing part has not been obtained. , mold 2Δ, molded product holding area 1j of mold 2B
This indicates that there is a possibility that the molded product 10 or a partially missing piece thereof remains on the area MA corresponding to 1 MB. Therefore, when the mold clamping driving means 4 of the injection molding machine 1 receives the mold clamping control signal ECI' of the mold clamping control signal ECI' of the injection molding machine 1 with a content that prohibits the index molding machine 1 from performing the mold clamping process. If the injection molding machine has a configuration in which the injection molding machine 1 is controlled so that the mold clamping process is not performed, the first mold clamping control signal EC1' causes the injection molding machine 1 to perform the mold clamping process. The injection molding machine 1 can be controlled so as not to remove the culm during the (i+1)th mold clamping. Further, the mold clamping drive means 4 of the injection molding machine 1 is configured to take the (i+1)th mold clamping step unless the ejection drive means 14 is controlled to take the first ejection step. The injection molding machine 1 has a configuration such that the ejection drive means 14 of the injection molding machine 1 is not
However, due to the first mold clamping control signal EC1', it becomes
If the injection molding Ia1 has a configuration such that when the injection molding Ia1 is obtained with content that prohibits the mold clamping process, the ejection process is not performed, the first When the mold clamping control signal @E C1' is obtained with content that prohibits the injection molding machine 1 from performing the mold clamping process, the injection molding machine 1 is controlled so as not to perform the first ejection process. Therefore, the injection molding machine 1 can be controlled so as not to perform the (i+1)th mold clamping step. Therefore, it is possible to effectively avoid the possibility that one or both of molds 2A and 2B will be damaged. Therefore, according to the injection molding machine control signal generating device according to the present invention shown in FIG. 2, the first mold clamping control signal output means 3

Therefore, the injection molding machine 1 is operated so that the (i+1)th mold clamping process leaves the molded product or a partially missing piece thereof on the area 1MA corresponding to the mold holding area MB of the mold 2B of the mold 2Δ. When the injection molding machine 1 performs the first mold opening process, the molded product 10 is placed on the molded product holding area MB of the mold 2B. When the molded product 1 is held as a working molded product that is equivalent to the reference molded product without any positional deviation or missing parts, the molded product 1
0 is protruded from the entire surface of the mold 2B by the first ejection process of the injection molding machine 1 without being held at all, the injection molded al. It is possible to control so that there is no fear that one or both of them will be damaged. Therefore, according to the signal generator for controlling an injection molding machine according to the present invention shown in FIG. 2, the molded product 10 is completely held on the entire surface GB of the mold 2B after the first ejection process is performed. If the injection molding machine 1 has a configuration in which there is no possibility that the state will not occur, the injection molding 811
can be controlled so that there is no fear that one or both of the molds 2A and 2B will be damaged. Such control can be performed without having to prepare a molded product holding area address information generation circuit 23 as in the case of the conventional injection molding machine control signal generation device described above in FIG.

1) This means that the molded product 10 is not held at all as a working molded product on the molded product holding area MB of the mold 2B during the paralysis period TQA-i during the second mold clamping step. From the above, when the second mold clamping control signal EC2' is obtained with content that allows the injection molding machine 1 to perform the mold clamping process, the second mold clamping control signal EC2' This indicates that the product 10 is not held at all as a working molded product on the molded product holding area MB of the mold 2B. Therefore, when the mold clamping driving means 4 of the injection molding machine 1 receives the second mold clamping control signal EC2' with a content that allows the injection molding machine 1 to perform the mold clamping process, If the injection molding machine 1 has a configuration that prevents the mold clamping process from being omitted, the second mold clamping control signal EC2 will cause the injection molding machine 1 to perform the mold clamping process. When the content is obtained that allows the tightening process, the injection molding machine 1 can be made to perform the (i+1)th mold clamping process. Even if the injection molding machine 1 is controlled to take the (i+1)th mold clamping step in this way, in this case, no molded product 10 is placed on the molded product holding area MB of the mold 2B. Since the molded article 10 is not held, the molded article 10 is injection molded 411
Through the first ejection process, the surface GB of mold 2B
Molded product holding area M is placed in the area other than the upper molded product holding area MB.
Unless the molded product 10 is held without facing S, and after the injection molding machine 1 takes the first mold opening step, the molded product 10 will not be completely covered with the entire surface GA of the mold 2A. As long as the state of not being held is obtained, there is no possibility that one or both of molds 2Δ and 2B will be damaged in the (i+1)th mold clamping step. Further, the second mold clamping control signal EC2' is transmitted to the injection molding machine 1.
What can be obtained by prohibiting the mold clamping process is:

As is clear from what has been described above in the section [Configuration of the Embodiment], the operation pattern information output means 34S after ejection

The brightness bQA'H of the information eQA'H at at least one address aQA'H in the molded product holding area determination reference pattern information ESP' at the address asP', csP', 1rlibsP' of This is a case where the brightness of the information eSFH at the address asF' of the pre-extrusion reference pattern information ESF' output from the pre-extrusion reference pattern information output means 348F has a value on the bsFH side. Here, the reference pattern information ESP for molded product holding area determination is

As mentioned above and for the reasons mentioned above, type 2
It is obtained as information regarding only the molded product holding area MB in the entire surface area GB of B. In addition, information eQA of operation pattern information EQA' after ejection
The brightness bQA' of ', is the brightness bsA' of the information eSA' of the post-extrusion reference pattern information ESA', as described above. , but has a different value from the brightness bsF'H of the information esF'H of the pre-extrusion reference pattern information ESF'. Therefore, information eQA of operation pattern information EQA after protrusion
', r4 degrees bQA', is the information eSP' of the reference pattern information ESP for molded product holding area determination, brightness bsp'
This means that the values of the pre-ejection reference pattern information ESF' and the brightness bsF' of the information eSF' and the brightness bsF' of the pre-ejection reference pattern information ESF' are better than ', respectively. In the sequential process of injection, mold opening and ejection

[During the period TQA-i from the pull-ejection process until the (i+1)th mold clamping process, the molded product 10 is placed on the molded product holding area iIiliMB of the mold 2B as a working molded product. This means that the state is not maintained at all. From the above, when the second mold clamping control signal EC2' is obtained with content that prohibits the injection molding machine 1 from performing the mold clamping process, the second mold clamping control signal EC2'
The molded product 10 is placed on the molded product holding area MB of the mold 2B,
This indicates that the molded product is not held at all as a working molded product. Therefore, when the mold clamping driving means 4 of the injection molding machine 1 receives the second mold clamping control signal EC2' with content that prohibits the injection molding unit 1f11 from performing the mold clamping process. If the injection molding machine 1 has a configuration in which the injection molding machine 1 is controlled so that the mold clamping process is not performed, the second mold clamping control signal E C2' causes the injection molding machine 1 to control the mold clamping process. As soon as the content that prohibits the tightening process is obtained, the injection molding machine 1 can be controlled so as not to remove one culm of the (i +1 )th mold clamping. For this reason, f! 1! It is possible to effectively avoid the possibility that one or both of 2A and 2B will lead to failure. Therefore, according to the injection molding machine control signal generating device according to the present invention shown in FIG. 2, the second mold clamping control signal output means 3
The second mold clamping control signal EC2' output from the mold 6C2 causes the injection molding machine 1 to hold the molded product 10 completely on the molded product holding area MB of the mold 2B during the (i+1)th mold clamping process. Injection molding machine 1
As long as the molded product 10 is not held on the entire surface of the mold 2A at all when the mold opening process is performed for the first time, and the injection molding machine 1 is opened for the first time. When the ejection step is taken, the molded article 10 is held in an area other than the molded article holding area MB on the surface GB of the mold 2B without facing inside the molded article holding area MB. Unless otherwise obtained, the injection molding machine 1, its mold 2
It is possible to control so that there is no fear that either one or both of A and 2B will be led to the failure member. Therefore, according to the signal generation system for controlling the injection molding machine according to the present invention shown in FIG. 2, when the first mold opening process is performed, the molded product 10 is completely held on the entire surface of the mold 2A When the first ejection process is performed, the molded product 10 is held in an area other than the molded product holding area MB on the surface GB of the mold 2B. If the injection molding machine 1 has a configuration in which there is no risk of being held without facing the area MB, the second mold clamping control signal EC

J3 can be controlled so that one or both of B is not damaged. Such control can be performed without having to prepare a molded product holding area address information generation circuit 23 as in the case of the conventional injection molding machine control signal generation device described above in FIG. In the injection molding machine 1, the set of molds 2A and 2B is placed in the molded product holding area 1fA of the mold 2B.
Even if the position, shape, area, etc. of the MB on the mold 2B are changed, the molded product holding area address can still be generated as in the case of the conventional injection molding machine control signal generator described above in FIG. This can be done automatically without the need to reset the circuit 23 so that the molded article holding area address information AD outputted therefrom represents the molded article holding area MB of the mold 2B in this case. Further, according to the injection molding machine control signal generating device according to the present invention shown in FIG. 2, as described above, the information eQA' of the post-ejection operation pattern information EQA' output from the post-ejection operation pattern information output means 34SA , eQA'b・

After the ejection step in the sequential steps of mold clamping, injection/extrusion, punching, and ejection, the molded product is inspected in TQA-i for 1-1 of the hog, taking 11JI of the <r+1>th mold-clamping. 10 means that a state in which 1 is not held at all as a working molded product on the entire surface of the mold 2B has not been obtained. From the above, the third mold clamping control signal EC3' is
When the injection molding machine 1 is obtained with content that prohibits the mold clamping process, the third mold clamping control signal EC3'
indicates that a state in which the molded product 10 is not held at all as a working molded product on the entire surface GB of the mold 2B cannot be obtained. Therefore, when the mold clamping driving means 4 of the injection molding Ia1 receives the third mold clamping control signal EC3' with content that prohibits the injection molding machine 1 from removing the mold clamping culm, the mold So that you don't have to go through the closing process.
If the injection molding machine 1 has a configuration in which the injection molding machine 1 is controlled, the third mold clamping control signal EC3' is obtained with content that prohibits the injection molding machine 1 from performing the mold clamping process. ,
The injection molding machine 1 can be controlled so as not to perform the (i-mo 1)-th mold clamping process. Therefore, it is possible to effectively avoid the possibility that one or both of molds 2A and 2B will be damaged. Therefore, according to the injection molding machine control signal generating device according to the present invention shown in FIG. 2, the third mold clamping control signal output means 3
According to the third mold clamping control signal EC3' output from 6C3, the injection molding machine 1 is controlled so that the (i+1)th mold clamping process does not hold the molded product 10 at all on the entire surface of the mold 2B. Since the injection molding machine 1 performs the first mold opening process, the molded product is completely spread over the entire surface of the mold 2A. As long as the state that the molds 2A and 2B are not held is maintained, the injection molding machine 1 can be controlled so that there is no possibility that one or both of the molds 2A and 2B will be damaged. Therefore, according to the signal generator for controlling an injection molding machine according to the present invention, which is not shown in FIG. There is no risk of it becoming unretained.
If the injection molding machine 1 has such a configuration, only the third mold clamping control signal EC3' will cause the injection molding machine 1 to be damaged in one or both of its molds 2A and 2B.

Even though 3' is obtained by prohibiting the injection molding machine 1 from performing the mold clamping process, injection molding! The third mold clamping control signal EC3 is obtained without the content of I11 permitting the mold clamping process to be performed.
can be correctly obtained by allowing the injection molding machine 11 to perform the mold clamping process or by prohibiting the injection molding machine 1 from performing the mold clamping process. Therefore, the above-mentioned functions and effects can be obtained without error. (D) Next, it will be described how the injection molding n1 can be controlled by the first mold clamping control signal ECI' and the second mold clamping control signal EC2'. According to the signal generator f for controlling an injection molding machine according to the present invention shown in FIG. 2, when the first ejection process is performed, the molded product 10 is not held at all on the entire surface GB of the mold 2B. If the injection molding machine 1 has a configuration that does not have the possibility of the state of not being present, injection molding can be performed only by the first mold clamping control signal @EC1'. 11 without the aforementioned drawbacks of the conventional injection molding machine control signal generator described above in FIG. I mentioned that it can be controlled without error. Further, when the first mold opening process is performed, there is no risk that the molded product 10 will not be held on the entire surface of the mold 2A at all, and the first ejection process is performed. When the process is taken, the molded product 10 is on the surface G
If the injection molding machine 1 has a configuration in which there is no possibility that the molded product is held in an area other than the molded product holding area MB on B without facing the molded product holding area M8, , the conventional method described above in FIG. It has also been mentioned that the signal generator for controlling an injection molding machine can be controlled without the above-mentioned drawbacks and without error. However, according to the signal generator for controlling an injection molding machine according to the present invention shown in FIG. and the second mold clamping control signal EC2 is obtained with content that permits the mold clamping process, the mold clamping process is controlled so as not to be performed.
After adopting this configuration and taking the first ejection step, the molded product 10 is placed in an area other than the molded product holding area M8 on the surface GB of the mold 2B without facing into the molded product holding area MB. If the injection molding machine 1 has a configuration in which there is no risk of the state being held, the first and second mold clamping control signals EC may be
Both 1' and EC2' allow the injection molding machine 1 to be controlled without error so that there is no possibility that one or both of its molds 2A and 2B will be damaged. Such control can be performed without having to prepare a molded product holding area address information generation circuit 23 as in the case of the conventional injection molding machine control signal generation device described above in FIG. In the injection molding machine 1, the set of molds 2A and 2B is placed in the molded product holding area MB of the mold 2B.
Even when the position, shape, area, etc. on the mold 2B are changed, the molded product holding area address generation circuit can be changed as in the case of the conventional injection molding machine control signal generation device described above in FIG. The molded product holding area address information AD outputted from 23 is the molded product holding area M of mold 2B in this case.
There is no need to reconfigure it to represent B.
It can be done automatically. (E) Next, how the injection molding machine 1 can be controlled by the first mold clamping control signal EC1' and the third mold clamping control signal EC3' will be described. According to the ready-to-use signal generator for the injection molding machine according to the present invention, which is not shown in FIG. If the injection molding machine 1 has a configuration in which there is no risk that the molds 2A and 2B In order to avoid the risk of damage to either or both of the injection molding machines, it is possible to control the injection molding machine without any of the drawbacks of the conventional injection molding machine control signal generator described above in FIG. 3 and without error. I said that. In addition, the injection molding machine 1 is configured so that there is no risk that the molded product 10 will not be held on the entire surface of the mold 2△ after the first mold opening process is performed. has the third mold clamping system 011 signal E
In order to prevent the injection molding machine 1 from being damaged by either or both of the molds 2Δ and 2B due to C3' alone, the conventional injection molding machine control signal generator described above in FIG. 3 is used. It has also been mentioned that the control can be carried out without the above-mentioned drawbacks and error-free. However, according to the signal generating bag for controlling the injection molding machine according to the present invention shown in FIG. and the third mold clamping control signal EC3 is obtained with content that permits the mold clamping process, the mold clamping process is controlled so that the mold clamping process is not skipped. If so, I will omit the detailed explanation, but
Both the first and third mold clamping control signals EC1' and EC3 cause the injection molding machine 1 to operate without error so that there is no possibility that one or both of its molds 2A and 2B will be guided into the coating. It can be controlled. Such control can be performed without having to prepare a molded product holding area address information generation circuit 23 as in the case of the conventional injection molding machine control signal generation device described above in FIG. In the injection molding machine 1, the set of molds 2A and 2B is placed in the molded product holding area MB of the mold 2B.
Even if the position, shape, area, etc. on the mold 2B are changed, the molded product holding area address generation circuit can be changed as in the case of the conventional injection molding machine control signal generation device described above in FIG.
