Description

Technical Field

[0001] This application claims priority based on Japanese Patent Application No. 2023-175474 filed on October 10, 2023. The entire contents of the Japanese Patent Application are incorporated herein by reference.

[0002] The invention relates to a molded product taking out system, a molding machine, a control device and a molded product taking out method. Background Art

[0003] Patent Document 1 discloses a technique for removing a molded product such as a preform from a mold of an injection molding machine. In Patent Document 1, a take-out machine is moved between open molds, and a molded product ejected from the mold by an ejector is removed from the mold by the take-out machine.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2004-114643

[0005] In recent years, due to the lightweighting of polyester bottles, i.e., thin-walling, or the emergence of small polyester bottles with a capacity of less than 200 ml, short preforms have been formed. Short preforms may fall from the gap between the take-out machine and the mold. Alternatively, short preforms may tilt in the gap and enter the take-out cylinder of the take-out machine obliquely, thereby colliding with the inner circumference of the take-out cylinder. The preform just taken out is not cooled enough, so if it collides with the inner circumference, it will be deformed.

[0006] This problem is not limited to preforms, but may also occur in other short molded products. Summary of the invention

[0007] The present invention has been made in view of such circumstances, and an exemplary object of one embodiment thereof is to provide a technology capable of suppressing removal defects of molded products.

[0008] In order to solve the above-mentioned problems, a molded product removal system according to one embodiment of the present invention comprises: a molding machine having a fixed platen with a fixed mold and a movable platen with a movable mold; a take-out machine for taking out the molded product; and a control device. The control device controls: making the take-out machine enter between the fixed mold and the movable mold of the mold opening; and moving at least one of the movable platen of the molding machine and the take-out machine in such a way that the molded product is relatively close to the take-out machine.

[0009] Another embodiment of the present invention is a molded product removal method. The molded product removal method removes a molded product from a molding machine having a fixed platen with a fixed mold and a movable platen with a movable mold, and the molded product removal method includes the following steps: allowing a removal machine to enter between the open fixed mold and the movable mold; and moving at least one of the movable platen and the removal machine in a manner that the molded product is relatively close to the removal machine.

[0010] In addition, any combination of the above-mentioned constituent elements, constituent elements or expressions of the present invention may be replaced with each other between methods, apparatuses, systems, etc., and these may also be additional embodiments of the present invention.

DETAILED DESCRIPTION

[0024] Hereinafter, the same or equivalent components, parts, and processes shown in the respective drawings are marked with the same reference numerals, and repeated descriptions are appropriately omitted. Furthermore, in order to facilitate understanding, the size of the parts shown in the respective drawings is appropriately enlarged or reduced. Furthermore, in the respective drawings, a part of the parts that are not important in explaining the embodiments is omitted and displayed.

[0025] Figure 1 It is a plan view showing a schematic structure of a molded product taking-out system 1 according to the embodiment. Figure 2 is along Figure 1 The sectional view cut along the AA line of FIG. As shown in the figure, the X-axis direction and the Y-axis direction are determined. The X-axis direction and the Y-axis direction are directions perpendicular to each other. The X-axis direction is consistent with the opening and closing direction of the mold 8. The Y-axis direction is consistent with the direction in which the robot 20 moves the take-out machine. The positive direction of each of the X-axis and the Y-axis is defined as the direction of the arrow in each figure, and the negative direction is defined as the direction opposite to the arrow.

[0026] The molded product removal system 1 includes a molding machine 2 that molds a molded product, a removal machine 30 that removes the molded product from the molding machine 2 , a robot 20 that moves the removal machine 30 , and a control device 4 .

[0027] In this embodiment, the molded product is a preform used in blow molding, especially a short preform. The preform is heated to a certain temperature in the blow molding process not described in this embodiment, and air is blown into the inside to expand and mold into a container such as a bottle or other hollow parts. In addition, the technical ideas of this embodiment can also be applied to molded products other than preforms, especially short molded products, as long as they are not contradictory.

[0028] The molding machine 2 includes a mold clamping device 10 , a fixed platen 50 fixed to a support frame 17 , a movable platen 52 movably mounted relative to the fixed platen 50 , and an injection device 6 for injecting a molding material.

[0029] The fixed platen 50 includes a fixed platen body 12 and a fixed die 13. The movable platen 52 includes a movable platen body 14 and a movable die 15. The fixed die 13 and the movable die 15 constitute the die 8.

[0030] The fixed mold 13 is mounted on the fixed platen body 12. The movable mold 15 is mounted on the movable platen body 14. The movable mold 15 has a protrusion 15a having a shape corresponding to a cavity (described later) of the preform 40. The fixed mold 13 has a recess (not shown) having a depth to accommodate the protrusion 15a. A cavity space of the preform 40 is formed between the protrusion 15a and the recess.

[0031] The movable platen body 14 is driven by a driving device (not shown) and moves in the X-axis direction along the connecting rod 16. By moving the movable platen body 14 relative to the fixed platen body 12, the mold 8 is closed, clamped, and opened.

[0032] The injection device 6 includes a cylinder 11 having a nozzle 11a at the front end. The injection device 6 is driven by a driving unit (not shown) to move in the X-axis direction, thereby approaching or moving away from the fixed platen body 12 and the mold 8. The injection device 6 inserts the nozzle 11a into a through hole (not shown) formed in the fixed platen body 12, and injects the molding material into the cavity space of the mold 8 in a state where the nozzle 11a is pressed against a gate bushing (not shown) mounted on a surface 13a of the fixed mold 13 on the side opposite to the movable mold 15. The preform 40 as a molded product is obtained by solidifying the molding material filled in the cavity space. The number of cavity spaces is, for example, plural, and a plurality of preforms 40 can be obtained at the same time. When the mold 8 is opened, the preform 40 adheres to the periphery of the plurality of protrusions 15a of the movable mold 15.

[0033] The take-out machine 30 moves between the fixed mold 13 and the movable mold 15 of the mold 8 that is opened. The take-out machine 30 is mounted on the front end arm 23 of the robot 20 and reciprocates along the Y-axis direction. The robot 20 has a sliding part 22 slidably mounted on a guide arm 21, which is mounted on a main body (not shown), and by moving the sliding part 22 along the guide arm 21, the front end arm 23 mounted on the sliding part 22 moves.

[0034] The take-out machine 30 has a take-out cylinder 31. In the example shown in the figure, the take-out machine 30 has a plurality of take-out cylinders 31. The plurality of take-out cylinders 31 are respectively installed at positions corresponding to the respective protrusions 15a of the movable mold 15. The take-out cylinder 31 accommodates the preform 40 transferred from the movable mold 15 inside. When the preform 40 is accommodated inside the take-out cylinder 31, the take-out machine 30 is retracted from between the fixed mold 13 and the movable mold 15, thereby being able to take out a plurality of preforms 40 from the mold 8 at the same time.

[0035] The control device 4 can be implemented by the cooperation of hardware resources and software resources, or can be implemented only by hardware resources. As hardware resources, components or circuits represented by CPU (Central Processing Unit) or memory can be used. As software resources, programs such as operating systems and applications can be used.

[0036] The control device 4 controls the molded product removal system 1 in a unified manner. That is, the control device 4 controls the molding machine 2, the removal machine 30, and the robot 20. For example, the control device 4 controls the driving device to move the movable platen body 14 relative to the fixed platen body 12. And, for example, Figure 1 As shown, the robot 20 is controlled to move the take-out machine 30 between the molds 8 or to retract the take-out machine 30 from between the molds 8 .

[0037] refer to Figure 3 An example of the preform 40 as a molded product will be described. Figure 3 The preform 40 shown is used to mold a bottle and is molded from PET resin. The preform 40 includes a body portion 40a that expands during the blow molding process to become a body portion of the bottle that contains liquid, and a head portion 40b that does not substantially expand during the blow molding process and becomes a threaded portion for screwing a cap or the like. A cavity portion 43 is formed inside the body portion 40a.

[0038] In this example, the body 40a has a hemispherical front end portion 40c, a cylindrical portion 40d, and an expanded portion 40e whose outer diameter increases as it approaches the head portion 40b. In addition, a structure in which the body 40a does not have the expanded portion 40e can also be considered. In this case, as in the example shown in the figure, the outer diameter D1 of the cylindrical portion 40d and the outer diameter D2 of the head portion 40b can be different from each other or the same as each other. In addition, considering the manufacturing, regardless of whether the body 40a has the expanded portion 40e, the cylindrical portion 40d can be provided with a draft angle, and specifically, it can be formed so that the outer diameter becomes extremely small as it approaches the front end portion 40c.

[0039] Figure 4 is along Figure 2 The sectional view is a BB line cut on the sectional view. The take-out machine 30 includes a plate body 32 and a plurality of take-out tubes 31 mounted on the plate body 32. The take-out tube 31 has a receiving hole 31a for receiving the preform 40. The receiving hole 31a includes a bottom 31c having a hemispherical bottom surface 31b, an inlet portion 31e having an opening 31d, and an intermediate portion 31g having a cylindrical inner peripheral surface 31f located between the bottom 31c and the inlet portion 31e. The inlet portion 31e is formed so that the diameter increases as it approaches the opening. A suction port 31j is formed on the bottom surface 31b. Air is sucked from the suction port by suction from a suction source not shown in the figure. Thus, the preform 40 is held in the receiving hole.

[0040] A flow path (not shown) is formed in the take-out cylinder 31. A refrigerant such as cold water flows in the flow path. Thus, the take-out cylinder 31 and the preforms 40 accommodated in the take-out cylinder 31 are cooled. That is, the take-out machine 30 is a liquid-cooling type.

[0041] exist Figure 4In the process, a preform 40 formed one cycle ago is held in every other take-out cylinder 31. This is to hold the preform 40 in the take-out cylinder 31 for one cycle amount of time and cool the preform 40 in the take-out cylinder 31 where the refrigerant flows. Alternatively, the preform 40 formed two or more cycles ago may be held.

[0042] The movable mold 15 includes a protruding portion 15a and a pair of split molds 15b corresponding to the head 40b of the preform 40. The pair of split molds 15b are driven by a driving unit (not shown) to move toward the take-out cylinder 31 as described later. As a result, the preform 40 is not fitted in the protruding portion 15a and moves toward the take-out cylinder 31.

[0043] Next, the removal operation of the preform 40 by the molded product removal system 1 will be described. Figures 5 to 10 This is a diagram for explaining an example of the removal operation of the preform 40 by the molded product removal system 1 in time series.

[0044] exist Figure 5 In the process, the take-out machine 30 moves between the fixed mold 13 and the movable mold 15 of the mold 8 that is opened. A preform 40 molded one or more cycles ago is held in a part of the plurality of take-out cylinders 31 of the take-out machine 30. The preform 40 molded in this cycle is held in the movable mold 15. That is, the preform 40 molded in this cycle is fitted in the protrusion 15a and is held by a pair of split molds 15b.

[0045] When the take-out machine 30 moves between the molds 8, a predetermined gap G is ensured between the take-out cylinder 31 and the protrusion 15a, which is independent of the length of the body 40a of the preform 40, so that the take-out cylinder 31 of the take-out machine 30 or the head 40b of the preform 40 held in the take-out cylinder 31 does not contact the protrusion 15a of the movable mold 15 or the preform 40 attached to the protrusion 15a. The size of the gap G can be determined according to the size L of the head 40b of the preform 40.

[0046] exist Figure 6 In the process, the movement of the take-out machine 30 is completed, and the take-out tube 31 faces the corresponding protrusion 15a in the X-axis direction.

[0047] exist Figure 7 In the process, the pair of split molds 15b holding the preform 40 is moved in the positive direction of the X axis. That is, the pair of split molds 15b are moved toward the take-out cylinder 31 together with the preform 40. In addition, as a modified example, the movement of the preform 40 based on the pair of split molds 15b can be started at the same time as the movement of the take-out machine 30 between the molds 8 is completed, and it can also be started before the movement of the take-out machine 30 between the molds 8 is completed (for example, just before completion) as long as there is no contact.

[0048] exist Figure 8 In the process, 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 the preform 40 .

[0049] exist Fig. 9 In the process, as shown by arrow A in the figure, the pair of split molds 15b are moved in the positive direction of the X-axis, i.e., toward the take-out machine 30, and the pair of split molds 15b are separated in a manner of moving away from each other in the Y-axis direction. As a result, the preform 40 is not fitted into the protruding portion 15a, and then, is no longer held by the pair of split molds 15b. The preform 40 is sucked into the deep part of the receiving hole 31a by suction.

[0050] exist Fig.10 In the process, the movable platen body 14 is moved in the negative direction of the X-axis. As a result, the protrusion 15a is protruded to the outside of the preform 40. In other words, the protrusion 15a no longer overlaps the preform 40, so the take-out machine 30 can be withdrawn from between the fixed mold 13 and the movable mold 15 of the mold 8 that is opened.

[0051] In the above-mentioned extraction operation, the movable platen 52 is moved so that the preform 40 moves toward the extraction cylinder 31. As a result, the preform 40 approaches the extraction cylinder 31, and it is possible to suppress the preform 40 from falling when the preform 40 is transferred from the mold 8 to the extraction cylinder 31. In addition, the movement of the movable platen 52 mentioned 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 body 14 in the positive direction of the X-axis.

[0052] Preferably, Fig. 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 portion of the front end portion 40c of the preform 40 is located in the inlet portion 31e of the take-out cylinder 31. This can more reliably suppress the preform 40 from falling.

[0053] 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 in the protrusion 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" means when the preform 40 is no longer held by the pair of split molds 15b, for example, when the pair of split molds 15b are opened in a manner away from each other in the Y-axis direction.

[0054] Further preferably, Fig. 9In the embodiment, when the preform 40 is no longer held by the movable mold 15, the movable platen 52 is moved so that at least a portion of the front end portion 40c of the preform 40 is located in the middle portion 31g of the take-out cylinder 31. As a result, the fall of the preform 40 can be further reliably suppressed. In addition, the collision between the preform 40 and the inner peripheral surface of the take-out cylinder 31, for example, the collision between the front end portion 40c of the preform 40 and the inner peripheral surface 31h of the entrance portion 31e of the take-out cylinder 31 can be suppressed.

[0055] Further preferably, Fig. 9 In the embodiment, when the preform 40 is no longer held by the movable mold 15, the movable platen 52 is moved so that at least a portion of the cylindrical portion 40d of the preform 40 is located in the middle portion 31g of the take-out cylinder 31. This can further reliably suppress the preform 40 from falling and colliding with the inner peripheral surface 31h of the take-out cylinder 31.

[0056] Not particularly limited, but may be Figures 7 to 9 At an appropriate time, gas F is blown into the preform 40 from the movable mold 15 to assist the movement of the preform 40.

[0057] In the above example, after the preform 40 is moved toward the take-out tube 31 by the split mold 15b, the preform 40 is further moved toward the take-out tube 31 by the movable platen body 14. However, the timing when the split mold 15b and the movable platen body 14 move the preform 40 is not limited to this.

[0058] For example, after the preform 40 is moved toward the take-out cylinder 31 by the movable platen body 14, the preform 40 may be further moved toward the take-out cylinder 31 by the split mold 15b. In this case, the preform 40 may enter the take-out cylinder 31 when the preform 40 is moved by the movable platen body 14, or the preform 40 may enter the take-out cylinder 31 when the preform 40 is moved by the split mold 15b. In addition, the movement of the preform 40 by the movable platen body 14 may be started at the same time as or after the completion of the movement of the take-out machine 30 to the mold 8, or may be started before the completion of the movement of the take-out machine 30 to the mold 8 as long as there is no contact.

[0059] Furthermore, for example, the movement of the preform 40 by the release die 15b and the movement of the preform 40 by the movable platen body 14 may be performed simultaneously. At this time, the movement of the preform 40 by the release die 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 release die 15b may be started first, or the movement of the preform 40 by the movable platen body 14 may be started first. Furthermore, the movement of the preform 40 by the release die 15b and the movement of the preform 40 by the movable platen body 14 may be terminated simultaneously, the movement of the preform 40 by the release die 15b may be terminated first, or the movement of the preform 40 by the movable platen body 14 may be terminated first. In addition, the movement of the preform 40 based on the parting mold 15b or the movable pressure plate body 14 can start at the same time as or after the completion of the movement of the take-out machine 30 between the molds 8, and can start before the completion of the movement of the take-out machine 30 between the molds 8 as long as there is no contact.

[0060] According to the present embodiment described above, the movable platen 52 is moved so that the preform 40 moves toward the take-out cylinder 31. As a result, the preform 40 approaches the take-out cylinder 31. For example, the preform 40 enters the take-out cylinder 31. Therefore, it is possible to suppress the preform 40 from falling when the preform 40 is transferred from the mold 8 to the take-out cylinder 31 or the preform 40 from colliding with the inner peripheral surface of the take-out cylinder 31.

[0061] In addition, it is possible to consider moving the take-out machine 30 to bring the preform 40 closer to the take-out tube 31. However, in this case, a mechanism is required to move the take-out machine 30 in the X-axis direction, stop it, and ensure the position of the take-out machine 30 in the X-axis direction, which increases the cost. Depending on the situation, it is necessary to add an axis for moving the take-out machine 30 in the X-axis direction, so that the number of components and the weight, that is, the inertia of the take-out machine 30 increase. If the number of components increases, the cost increases. If the inertia of the take-out machine 30 increases, the power required for braking the take-out machine 30 increases, so the power consumption increases. In addition, if the inertia of the take-out machine 30 increases, the time required for braking the take-out machine 30 becomes longer, so the movement of the take-out machine 30 takes time, which may increase the cycle time.

[0062] In contrast, when the preform 40 and the take-out tube 31 are brought close to each other by moving the movable platen 52, these problems can be avoided. That is, the take-out machine 30 can be simplified and lightened compared to the case where the take-out machine 30 is moved. In addition, the cycle time can be shortened. Furthermore, when the preform 40 and the take-out tube 31 are brought close to each other by moving the movable platen 52, for example, it can be realized by only improving the software of the conventional equipment.

[0063] The present invention has been described above based on the embodiments. It should be understood by those skilled in the art that the embodiments are examples, and that the combinations of the constituent elements and the processing procedures may have various modifications, and such modifications are also within the scope of the present invention.

[0064] (Variant 1)

[0065] 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 is described, but the present invention is not limited thereto, and the preform 40 can be relatively moved toward the take-out tube 31 by moving the take-out machine 30 in the negative direction of the X-axis. In this case, a mechanism is required to move the take-out machine 30 in the X-axis direction, stop it, and ensure the position of the take-out machine 30 in the X-axis direction.

[0066] (Variant 2)

[0067] 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 is described, but the present invention is not limited thereto. The movable platen body 14 may be moved in the positive direction of the X-axis, and the take-out machine 30 may be moved in the negative direction of the X-axis, that is, in the direction close to the preform 40, so that the preform 40 is relatively moved toward the take-out tube 31. At this time, the amount of movement of the take-out machine 30 in the negative direction of the X-axis may be less than the amount of movement of the movable platen 52. For example, the amount of movement of the take-out machine 30 in the negative direction of the X-axis may be less than the total amount of movement of the movable platen body 14 in the positive direction of the X-axis and the amount of movement of the pair of split molds 15b in the positive direction of the X-axis. Furthermore, for example, the amount of movement of the take-out machine 30 in the negative direction of the X-axis may be less than the amount of movement of the movable platen body 14 in the positive direction of the X-axis. Furthermore, the timing of moving the movable platen body 14 and the take-out machine 30 is not particularly limited. For example, the movable platen body 14 and the take-out machine 30 may be moved simultaneously or at different times. According to this modification, compared with the case where only the take-out machine 30 is moved, the movement amount of the take-out machine 30 can be reduced, the mechanism for moving the take-out machine 30 can be reduced, and the increase in the weight, i.e., the inertia, of the take-out machine 30 can be suppressed.

[0068] (Variant 3)

[0069] In the embodiment, the case where the take-out machine 30 is configured to cool the preform 40 by liquid has been described, but the present invention is not limited thereto, and the take-out machine 30 may be configured to cool the preform 40 by air.

[0070] Any combination of the above-mentioned embodiments and variations is also effective as an embodiment of the present invention. The new embodiment generated by the combination has the effects of the combined embodiments and variations. In addition, those skilled in the art should also understand that the functions of the various components recorded in the scheme are realized by the monomers of the various components shown in the embodiments and variations or their cooperation.
