[0003] [Patent Document 1] JP 2004-114643 A Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, the lightening of PET bottles (i.e., the thinning of the walls) and the appearance of small PET bottles with a capacity of 200 ml or less have led to the molding of short and small preforms. Short and small preforms may fall through the gap between the take-out machine and the mold. Alternatively, short and small preforms may tilt in the gap and enter the take-out tube of the take-out machine at an angle, colliding with the inner circumferential surface of the take-out tube. Since the preforms are not sufficiently cooled immediately after being taken out, they will deform when they collide with the inner circumferential surface.

[0005] Such problems are not limited to preforms, but may occur in other small and short molded products.

[0006] The present invention has been made in light of these circumstances, and one exemplary purpose of an embodiment of the present invention is to provide a technique capable of preventing defects in removing a molded product. [Means for solving the problem]

[0007] In order to solve the above problems, a molded product removal system according to one aspect of the present invention includes a molding machine having a fixed platen with a fixed mold and a movable platen with a movable mold, a remover for removing the molded product, and a control device. The control device causes the remover to enter between the fixed mold and the movable mold that have been opened, and moves at least one of the movable platen of the molding machine and the remover so that the molded product approaches the remover relatively.

[0008] Another aspect of the present invention is a method for removing a molded product from a molding machine equipped with a fixed platen having a fixed mold and a movable platen having a movable mold, the method comprising: inserting a remover between the fixed mold and the movable mold that have been opened, and moving at least one of the movable platen and the remover so that the molded product approaches relatively close to the remover.

[0009] Any combination of the above components, or mutual substitution of the components or expressions of the present invention between methods, devices, systems, etc. are also valid aspects of the present invention. Effect of the Invention

[0010] According to the present invention, a technique can be provided that can prevent defects in removing a molded product. [Brief description of the drawings]

[0012] Hereinafter, the same or equivalent components, parts, and steps shown in each drawing will be given the same reference numerals, and duplicated explanations will be omitted as appropriate. Also, the dimensions of the parts in each drawing will be enlarged or reduced as appropriate to facilitate understanding. Also, some of the parts that are not important for explaining the embodiment will be omitted in each drawing.

[0013] Fig. 1 is a plan view showing an outline of a molded product removal system 1 according to an embodiment. Fig. 2 is a cross-sectional view taken along line AA in Fig. 1. The X-axis and Y-axis directions are defined as shown in the figure. The X-axis and Y-axis directions are perpendicular to each other. The X-axis direction coincides with the opening and closing direction of the mold 8. The Y-axis direction coincides with the direction in which the robot 20 moves the remover. The positive directions of the X-axis and Y-axis are defined as the directions of the arrows in each figure, and the negative directions are defined as the directions opposite to the arrows.

[0014] The molded product removal system 1 includes a molding machine 2 that molds a molded product, a remover 30 that removes the molded product from the molding machine 2, a robot 20 that moves the remover 30, and a control device 4.

[0015] In this embodiment, the molded product is a preform used in blow molding, particularly a small and short preform. The preform is heated to a certain temperature in a blow molding process not described in this embodiment, and air is blown into the preform to expand it and mold it into a container such as a bottle or other hollow member. The technical concept of this embodiment can also be applied to molded products other than preforms, particularly small and short molded products, as long as there is no contradiction.

[0016] The molding machine 2 includes a mold clamping device 10, a fixed platen 50 fixed to a support frame 17, a movable platen 52 attached so as to be movable relative to the fixed platen 50, and an injection device 6 that injects a molding material.

[0017] The stationary platen 50 includes a stationary platen body 12 and a stationary mold 13. The movable platen 52 includes a movable platen body 14 and a movable mold 15. The stationary mold 13 and the movable mold 15 constitute a mold 8.

[0018] The fixed mold 13 is attached to the fixed platen body 12. The movable mold 15 is attached to the movable platen body 14. The movable mold 15 has a protruding portion 15a having a shape corresponding to a hollow portion (described later) of the preform 40. The fixed mold 13 has a recessed portion (not shown) having a depth sufficient to accommodate the protruding portion 15a. A cavity space for the preform 40 is formed between this protruding portion 15a and the recessed portion.

[0019] The movable platen body 14 is driven by a drive device (not shown) and moves in the X-axis direction along the tie bars 16. By moving the movable platen body 14 relative to the fixed platen body 12, the mold 8 is closed, clamped, and opened.

[0020] The injection device 6 includes a cylinder 11 having a nozzle 11a at its tip. The injection device 6 is driven by a drive unit (not shown) to move in the X-axis direction, approaching or moving away from the stationary platen body 12 and the mold 8. The injection device 6 inserts the nozzle 11a into a through hole (not shown) formed in the stationary platen body 12, and injects molding material into the cavity space of the mold 8 while pressing the nozzle 11a against a spool bush (not shown) attached to the surface 13a of the stationary mold 13 opposite to the movable mold 15. The molding material filled in the cavity space is solidified to obtain a preform 40 as a molded product. For example, the number of cavity spaces is multiple, and multiple preforms 40 are obtained at the same time. When the mold 8 is opened, the preforms 40 are attached to the periphery of the multiple protrusions 15a of the movable mold 15.

[0021] The remover 30 moves between the fixed mold 13 and the movable mold 15 of the mold 8 that has been opened. The remover 30 is attached to the tip arm 23 of the robot 20, and moves back and forth in the Y-axis direction. The robot 20 has a slide part 22 slidably attached to a guide arm 21 attached to a main body part (not shown), and the tip arm 23 attached to the slide part 22 is moved by moving the slide part 22 along the guide arm 21.

[0022] The ejector 30 has a take-out tube 31. In the illustrated example, the ejector 30 has a plurality of take-out tubes 31. The plurality of take-out tubes 31 are attached at positions corresponding to the respective protruding portions 15a of the movable mold 15. The take-out tube 31 accommodates therein the preforms 40 delivered from the movable mold 15. With the preforms 40 accommodated inside the take-out tube 31, the ejector 30 is retracted from between the fixed mold 13 and the movable mold 15, whereby the plurality of preforms 40 can be simultaneously removed from the mold 8.

[0023] The control device 4 can be realized by a combination of hardware and software resources, or by hardware resources alone. As hardware resources, elements and circuits such as a CPU (Central Processing Unit) and memory can be used. As software resources, programs such as an operating system and applications can be used.

[0024] The control device 4 comprehensively controls the molded product removal system 1. That is, the control device 4 controls the molding machine 2, the remover 30, and the robot 20. For example, the control device 4 controls the drive device to move the movable platen body 14 relative to the fixed platen body 12. Also, for example, the control device 4 controls the robot 20 to move the remover 30 between the molds 8 as shown in FIG. 1 and to retract the remover 30 from between the molds 8.

[0025] An example of a preform 40 as a molded product will be described with reference to Fig. 3. The preform 40 shown in Fig. 3 is for molding a bottle, and is molded from PET resin. The preform 40 includes a body portion 40a that is expanded in the blow molding process to become the body portion of the bottle that contains liquid, and a neck portion 40b that is not substantially expanded in the blow molding process and becomes a mouth portion equipped with a screw onto which a cap or the like is screwed. A hollow portion 43 is formed inside the body portion 40a.

[0026] In this example, the body 40a has a hemispherical tip 40c, a cylindrical portion 40d, and an expanded diameter portion 40e whose outer diameter increases toward the neck 40b. It is also possible that the body 40a does not have the expanded diameter portion 40e. In this case, the outer diameter D1 of the cylindrical portion 40d and the outer diameter D2 of the neck 40b may be different from each other as in the illustrated example, or may be the same as each other. Furthermore, the cylindrical portion 40d may have a draft angle in consideration of manufacturing, regardless of whether the body 40a has the expanded diameter portion 40e or not, and specifically, may be formed so that the outer diameter becomes very slightly smaller toward the tip 40c.

[0027] 4 is a cross-sectional view of line BB in FIG. 2. The extractor 30 includes a plate 32 and a plurality of take-out tubes 31 attached to the plate 32. The take-out tube 31 has a storage hole 31a for storing the preform 40. The storage hole 31a includes a bottom 31c having a hemispherical bottom surface 31b, an inlet 31e having an opening 31d, and an intermediate portion 31g having a cylindrical inner circumferential surface 31f located between the bottom 31c and the inlet 31e. The inlet 31e is formed so that the diameter becomes larger as it approaches the opening. A suction port 31j is formed in the bottom 31b. Air is sucked from the suction port by suction from a suction source (not shown). As a result, the preform 40 is held in the storage hole.

[0028] A flow path (not shown) is formed in the take-out tube 31. A coolant such as cold water flows through this flow path. This cools the take-out tube 31 and, by extension, the preforms 40 accommodated in the take-out tube 31. In other words, the extractor 30 is of a liquid-cooling type.

[0029] In Fig. 4, every other take-out cylinder 31 holds a preform 40 molded one cycle ago. This is to hold the preform 40 in the take-out cylinder 31 for one cycle longer, and to cool the preform 40 in the take-out cylinder 31 through which the refrigerant flows. Note that it is also possible to hold preforms 40 from two or more cycles ago.

[0030] The movable mold 15 includes a protruding portion 15a and a pair of split molds 15b corresponding to the neck portion 40b of the preform 40. The pair of split molds 15b are driven by a driving unit (not shown) to move toward the takeout tube 31 as described below. As a result, the preform 40 moves toward the takeout tube 31 without engaging with the protruding portion 15a.

[0031] Next, a description will be given of the operation of removing the preform 40 by the molded product removal system 1. Figures 5 to 10 are diagrams for explaining an example of the operation of removing the preform 40 by the molded product removal system 1 in chronological order.

[0032] In Fig. 5, the ejector 30 moves toward the gap between the fixed mold 13 and the movable mold 15 of the mold open 8. Preforms 40 molded one or more cycles ago are held in some of the multiple takeout tubes 31 of the ejector 30. The preform 40 molded in the current cycle is held in the movable mold 15. That is, the preform 40 molded in the current cycle is fitted into the protruding portion 15a and held by the pair of split molds 15b.

[0033] When the ejector 30 moves between the molds 8, a predetermined gap G that does not depend on the length of the body 40a of the preform 40 is secured between the takeout tube 31 and the protruding portion 15a so that the takeout tube 31 of the ejector 30 and the neck 40b of the preform 40 held in the takeout tube 31 do not come into contact with the protruding portion 15a of the movable mold 15 and the preform 40 attached to the protruding portion 15a. The size of the gap G may be determined based on the dimension L of the neck 40b of the preform 40.

[0034] In FIG. 6, the movement of the dispenser 30 is completed, and the takeout tube 31 faces the corresponding protrusion 15a in the X-axis direction.

[0035] 7, the pair of split dies 15b holding the preform 40 is moved in the positive direction of the X-axis. That is, the pair of split dies 15b is moved toward the takeout tube 31 together with the preform 40. As a modified example, the movement of the preform 40 by the pair of split dies 15b may be started simultaneously with the completion of the movement of the ejector 30 to between the dies 8, or may be started before the completion of the movement of the ejector 30 to between the dies 8 (for example, immediately before the completion) as long as the timing does not cause contact.

[0036] 8, the movable platen body 14 is moved in the positive direction of the X-axis. That is, the movable platen body 14 is moved toward the take-out cylinder 31 together with the movable mold 15 and thus the preform 40.

[0037] 9, as shown by the arrow A in the figure, the pair of split dies 15b are moved in the positive direction of the X-axis, i.e., toward the extractor 30, and the pair of split dies 15b are opened so as to move away from each other in the Y-axis direction. As a result, the preform 40 is no longer fitted into the protruding portion 15a, and is no longer held by the pair of split dies 15b. The preform 40 is sucked deep into the receiving hole 31a by suction.

[0038] 10, the movable platen body 14 is moved in the negative direction of the X-axis. This causes the protruding portion 15a to move out of the preform 40, in other words, the protruding portion 15a no longer overlaps with the preform 40, so that the demolder 30 can be removed from between the fixed mold 13 and the movable mold 15 of the opened mold 8.

[0039] In the above-described removal operation, the movable platen 52 is moved so that the preform 40 moves toward the takeout cylinder 31. This brings the preform 40 closer to the takeout cylinder 31, and prevents the preform 40 from dropping when it is transferred from the mold 8 to the takeout cylinder 31. Note that the movement of the movable platen 52 here includes the movement of the pair of split molds 15b in the positive direction of the X axis and the movement of the movable platen main body 14 in the positive direction of the X axis.

[0040] 9, when the preform 40 is no longer held by the movable mold 15, the movable platen 52 is moved so that at least a part of the tip portion 40c of the preform 40 is positioned within the inlet portion 31e of the take-out tube 31. This makes it possible to more reliably prevent the preform 40 from falling.

[0041] Here, the state in which the preform 40 is not held by the movable mold 15 refers to a state in which the preform 40 is not fitted into the protruding portion 15a and is not held by the pair of split molds 15b. Therefore, "when the preform 40 is no longer held by the movable mold 15" refers to a state in which the preform 40 is no longer held by the pair of split molds 15b, and may be, for example, a state in which the pair of split molds 15b open so as to move away from each other in the Y-axis direction.

[0042] More preferably, when the preform 40 is no longer held by the movable mold 15 in Fig. 9, the movable platen 52 is moved so that at least a part of the tip 40c of the preform 40 is located within the middle part 31g of the takeout tube 31. This makes it possible to more reliably prevent the preform 40 from falling. In addition, it is possible to prevent a collision between the preform 40 and the inner peripheral surface of the takeout tube 31, for example, a collision between the tip 40c of the preform 40 and the inner peripheral surface 31h of the inlet part 31e of the takeout tube 31.

[0043] More preferably, the movable platen 52 is moved so that at least a part of the cylindrical portion 40d of the preform 40 is positioned within the middle portion 31g of the takeout tube 31 when the preform 40 is no longer held by the movable mold 15 in Fig. 9. This makes it possible to more reliably prevent the preform 40 from falling and colliding with the inner peripheral surface 31h of the takeout tube 31.

[0044] Although not particularly limited, the movement of the preform 40 may be assisted by blowing air F from the movable mold 15 onto the preform 40 at appropriate timing in FIGS.

[0045] In the above example, the case was described in which the split mold 15b moves the preform 40 toward the takeout tube 31, and then the movable platen main body 14 moves the preform 40 further toward the takeout tube 31, but the timing at which the split mold 15b and the movable platen main body 14 move the preform 40 is not limited to this.

[0046] For example, the preform 40 may be moved toward the takeout tube 31 by the movable platen body 14, and then the split mold 15b may further move the preform 40 toward the takeout tube 31. In this case, the preform 40 may enter the takeout tube 31 when moved by the movable platen body 14, or the preform 40 may enter the takeout tube 31 when moved by the split mold 15b. The movement of the preform 40 by the movable platen body 14 may be started simultaneously with or after the completion of the movement of the ejector 30 between the molds 8, or may be started before the completion of the movement of the ejector 30 between the molds 8 as long as the timing does not cause contact.

[0047] For example, the movement of the preform 40 by the split mold 15b and the movement of the preform 40 by the movable platen body 14 may be performed simultaneously. In this case, the movement of the preform 40 by the split mold 15b and the movement of the preform 40 by the movable platen body 14 may be started simultaneously, the movement of the preform 40 by the split mold 15b may be started first, or the movement of the preform 40 by the movable platen body 14 may be started first. The movement of the preform 40 by the split mold 15b and the movement of the preform 40 by the movable platen body 14 may be ended simultaneously, the movement of the preform 40 by the split mold 15b may be ended first, or the movement of the preform 40 by the movable platen body 14 may be ended first. The movement of the preform 40 by the split mold 15b or the movable platen body 14 may be started simultaneously with or after the completion of the movement of the take-out machine 30 between the molds 8, or may be started before the completion of the movement of the take-out machine 30 between the molds 8 as long as it is a timing that does not cause contact.

[0048] According to the present embodiment described above, the movable platen 52 is moved so that the preform 40 moves toward the takeout tube 31. This brings the preform 40 closer to the takeout tube 31. For example, the preform 40 enters the takeout tube 31. This makes it possible to prevent the preform 40 from falling or colliding with the inner peripheral surface of the takeout tube 31 when the preform 40 is transferred from the mold 8 to the takeout tube 31.

[0049] It is also possible to move the take-out machine 30 to bring the preform 40 and the take-out tube 31 closer to each other. However, in this case, a gimmick is required to move and stop the take-out machine 30 in the X-axis direction and to ensure the position of the take-out machine 30 in the X-axis direction, which is costly. In some cases, it is necessary to add an axis for moving the take-out machine 30 in the X-axis direction, and the number of parts of the take-out machine 30 and its weight, i.e., inertia, increase. The increase in the number of parts increases the cost. When the inertia of the take-out machine 30 increases, the power required to brake the take-out machine 30 increases, and therefore the power consumption increases. Also, when the inertia of the take-out machine 30 increases, the time required to brake the take-out machine 30 increases, so it takes time to move the take-out machine 30, and the cycle time may be longer.

[0050] On the other hand, if the preform 40 and the take-out tube 31 are brought closer to each other by moving the movable platen 52, these problems can be avoided. That is, compared to the case where the take-out device 30 is moved, the take-out device 30 can be simplified and made lighter. Also, the cycle time can be shortened. Also, if the preform 40 and the take-out tube 31 are brought closer to each other by moving the movable platen 52, this can be realized, for example, simply by improving the software of a conventional machine.

[0051] The present invention has been described above based on an embodiment. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component and each treatment process, and that such modifications are also within the scope of the present invention.

[0052] (Variation 1) In the embodiment, the case where the preform 40 is moved toward the take-out tube 31 by moving the movable platen body 14 in the positive direction of the X-axis has been described, but the present invention is not limited to this, and the preform 40 may be moved relatively toward the take-out tube 31 by moving the extractor 30 in the negative direction of the X-axis. In this case, a gimmick is required to move and stop the extractor 30 in the X-axis direction and to guarantee the position of the extractor 30 in the X-axis direction.

[0053] (Variation 2) In the embodiment, the case where the preform 40 is moved toward the take-out tube 31 by moving the movable platen body 14 in the positive direction of the X-axis has been described, but the present invention is not limited thereto. The preform 40 may be moved relatively toward the take-out tube 31 by moving the movable platen body 14 in the positive direction of the X-axis and moving the extractor 30 in the negative direction of the X-axis, i.e., in the direction approaching the preform 40. In this case, the movement amount of the extractor 30 in the negative direction of the X-axis may be less than the movement amount of the movable platen 52. For example, the movement amount of the extractor 30 in the negative direction of the X-axis may be less than the total movement amount of the movement amount of the movable platen body 14 in the positive direction of the X-axis and the movement amount of the pair of split molds 15b in the positive direction of the X-axis. Also, for example, the movement amount of the extractor 30 in the negative direction of the X-axis may be less than the movement amount of the movable platen body 14 in the positive direction of the X-axis. Furthermore, there is no particular limitation on the timing at which the movable platen body 14 and the unloader 30 are moved. For example, the movable platen body 14 and the unloader 30 may be moved simultaneously, or at separate times. According to this modification, compared to the case in which only the unloader 30 is moved, the movement amount of the unloader 30 can be reduced, the gimmick for moving the unloader 30 can be made smaller, and an increase in the weight, i.e., inertia, of the unloader 30 can be suppressed.

[0054] (Variation 3) In the embodiment, the case where the ejector 30 is configured to liquid-cool the preforms 40 has been described, but the present invention is not limited to this, and the ejector 30 may be configured to air-cool the preforms 40 .

[0055] Any combination of the above-mentioned embodiments and modifications is also useful as an embodiment of the present invention. A new embodiment resulting from the combination has the effects of the combined embodiments and modifications. It will also be understood by those skilled in the art that the functions to be performed by each component recited in the claims can be realized by each component shown in the embodiments and modifications alone or in cooperation with each other.
