Description

Technical Field

[0001] The present invention relates to a display device for an injection device, an injection device, and an injection molding machine, which include a heating cylinder for displaying an injection device, a screw, a heater, and a temperature sensor on a display screen. Background Art

[0002] An injection molding machine includes an injection device for injecting an injection material, a mold clamping device for clamping a mold, etc., and a controller controls according to molding conditions set by a user. For example, as shown in Patent Document 1, the controller has a screen for setting molding conditions, and the user can set desired molding conditions from this screen.

[0003] As molding conditions set by the user, they include the temperatures of the heating cylinder and the injection nozzle. A plurality of heaters are provided along the axial direction of the heating cylinder. The plurality of heaters are divided into a plurality of heater groups in units of one or more heaters, and from the upstream side where the hopper is located to the downstream side where the injection nozzle is provided, for example, they become heater groups H1, H2,.... The user sets a desired temperature for each heater group. One or more heaters are also provided on the injection nozzle, and these heaters are also divided into one or more heater groups NH1 and NH2, and the temperature is set by the user.

[0006] Patent Document 1: Japanese Patent Application Laid-Open No. 2003-19736 Summary of the Invention

[0007] Problems to be Solved by the Invention

[0008] When the user considers the temperatures set for each of the heater groups H1, H2,..., NH1,..., the so-called regions formed in the heating cylinder are considered. The inside of the heating cylinder is divided into a plurality of regions by a screw whose thread shape changes from the upstream side to the downstream side. For example, a supply region where the injection material is melted in the upstream region, a compression region where the melted injection material is compressed on the downstream side thereof, and a metering region on the downstream side. The user sets the temperatures of the heater groups H1, H2,..., NH1,... in consideration of these regions.

[0009] Incidentally, the lengths of the heater groups H1, H2, ..., NH1, ... in the axial direction are not constant, but vary in length. There is a problem of requiring proficiency because the user has to consider the axial lengths of the respective heater groups H1, H2, ..., NH1, ... and set the temperature based on the relationship with the regions. In addition, it should be noted that the position of the region divided by the screw changes in the heating cylinder when the screw retracts due to metering. The user has to set the temperatures of the heater groups H1, H2, ..., NH1, ... taking into account the change in the region according to the position of the screw. However, since the temperature setting screen provided to the controller does not have information associating the arrangement of the heater groups H1, H2, ... with the position of the screw, there is a problem that it is difficult for users with insufficient proficiency to set the temperature.

[0010] In the present disclosure, there is provided a display device for an injection device, which includes a display screen capable of grasping the positional relationship between a heater group and a screw.

[0011] Other objects and novel features will become apparent from the description of this specification and the drawings.

[0012] Means for Solving the Problem

[0013] The present disclosure is configured as a display screen of an injection device. In the injection device, a plurality of heaters provided in a heating cylinder and an injection nozzle are divided into a plurality of heater groups in units of one or adjacent ones. In the display screen, the heating cylinder, the injection nozzle, and the plurality of heaters are displayed in cross-section, and the screw is displayed in surface shape. And when the axial direction of the screw is taken as the axial direction, for their respective shapes and arrangements, they are displayed at substantially the same scale as the actual size in the axial direction. In addition, an identifier for identifying the heater group is displayed near each of the plurality of heater groups.

[0014] Advantageous Effects of the Invention

[0015] According to the present disclosure, the user can grasp the positional relationship between the heater group and the screw. Description of the Drawings

In each figure, the same reference numerals are assigned to the same elements, and repeated explanations are omitted as needed. In addition, in order to avoid confusion in the drawings, hatching is omitted in some parts.

[0044] [First Embodiment]

[0045] <Injection Molding Machine>

[0046] As Figure 1 shown, the injection molding machine 1 according to the first embodiment is configured to include a mold clamping device 2, an injection device 3, etc. The injection molding machine 1 includes a controller, that is, a control device 4, and the mold clamping device 2 and the injection device 3 are controlled by the control device 4. The control device 4 is provided with a display 5. The display 5 is arranged to display the cylinder temperature setting and display screen according to the first embodiment described later, and other screens.

[0047] <Mold Clamping Device>

[0048] The mold clamping device 2 includes a fixed plate 7 fixed to the base B, a movable plate 8 slidably arranged on the base B, and a mold clamping housing 9. The fixed plate 7 and the mold clamping housing 9 are connected by a plurality of tie rods 11, 11,... The movable plate 8 is arranged to be slidable between the fixed plate 7 and the mold clamping housing 9. A mold clamping mechanism, that is, the toggle mechanism 13 in the present embodiment, is arranged between the mold clamping housing 9 and the movable plate 8. The fixed plate 7 and the movable plate 8 are respectively provided with a fixed-side mold 15 and a movable-side mold 16. Therefore, when the toggle mechanism 13 is driven, the molds 15, 16 are opened and closed.

[0049] <Injection Device>

[0050] The injection device 3 includes a heating cylinder 19, a screw 20 arranged in the heating cylinder 19, and a screw driving device 22. The heating cylinder 19 is supported by the screw driving device 22, and the screw 20 is arranged to be driven by the screw driving device 22 in the rotational direction and the axial direction. The heating cylinder 19 is provided with a hopper 23 and an injection nozzle 24.

[0051] Figure 2 shows the heating cylinder 19, the screw 20, and the injection nozzle 24 with the actual object reduced at a certain scale for the injection device 3 according to the first embodiment. InFigure 2 In [the figure], the screw 20 is shown in its surface shape, and the heating cylinder 19 and the injection nozzle 24 are shown in cross-section, but no hatching is applied to indicate the cross-section.

[0052] The heating cylinder 19 and the injection nozzle 24 are provided with a plurality of heaters 25, 25,.... These heaters 25, 25,... are divided into a plurality of heater groups H1, H2,... in units of one or adjacent multiples. Specifically, in the first embodiment, at the heating cylinder 19, from the hopper mounting portion HP side, i.e., the upstream side, downstream in sequence, one heater 25 is the heater group H1, the next heater 25 is the heater group H2, the next adjacent two heaters 25, 25 are the heater group H3, and the last adjacent two heaters 25, 25 are the heater group H4. In the injection nozzle 24, one heater 25 on the upstream side is the heater group NH1, and one heater 25 on the downstream side is the heater group NH2.

[0053] Temperature sensors S1, S2,..., NS2 are embedded in the heating cylinder 19 and the injection nozzle 24 to correspond to these heater groups H1, H2,..., NH2. That is, the temperature sensors S1, S2,... S4 are respectively embedded in the heating cylinder 19 to correspond to the heater groups H1, H2,..., H4, and the temperature sensors NS1, NS2 are respectively embedded in the injection nozzle 24 to correspond to the heater groups NH1, NH2. At the heating cylinder 19, a temperature sensor HPS is also embedded in the hopper mounting portion HP.

[0054] Threads 27 are formed on the screw 20. Since the shape of the threads 27 varies in the axial direction, as a result, the depth of the grooves between the threads 27 is deeper on the upstream side, gradually becomes shallower in the middle, and shallower on the downstream side. Thus, the interior of the heating cylinder 19 according to the first embodiment is divided into three regions. That is, from the downstream side to the upstream side, it is divided into a supply region Z1, a compression region Z2, and a metering region Z3.

[0055] <Cylinder Temperature Setting and Display Screen>

[0056] Through Figure 3A 、 Figure 3B And Figure 3C The cylinder temperature setting and display screen 30 according to the first embodiment will be described. As Figure 3A Shown, the cylinder temperature setting and display screen 30 is configured to include an injection device image display bar 31 in the upper part and a temperature setting and display bar 32 in the lower part.

[0057] In the first embodiment, the injection device image display bar 31 displays an image of the injection device 3 according to the first embodiment (see Figure 2 ) substantially reduced at a certain scale. More precisely, with the screw 20 (seeFigure 2 ) The direction of the axis of () is taken as the axis direction, and the direction orthogonal to the axis direction is taken as the orthogonal direction. In the injection device image display column 31, there is shown an image of the heating cylinder 19, the screw 20, the injection nozzle 24, the heaters 25, 25,... and the temperature sensors S1, S2,... in the axial direction and the orthogonal direction, substantially reduced in scale at a certain ratio. Figure 2

[0058] In the injection device image display column 31, the identifiers "H1", "H2",...,"NH2" of the heater groups H1, H2,... NH2 are shown in corresponding association with the plurality of heaters 25, 25,... (see Figure 2 ). In addition, although not a heater group, the identifier "HP" representing the hopper mounting portion HP is also shown. Further, in the injection device image display column 31, the identifiers "S1", "S2",...,"NS2", "HPS" of the temperature sensors S1, S2,... NS2, HPS (see Figure 2 ) are shown in corresponding association with the temperature sensors S1, S2,... (see Figure 2 ).

[0059] In the injection device image display column 31, an image of the screw 20 (see Figure 2 ) is shown, and a plurality of regions corresponding to and associated with the screw 20 and the words "Supply", "Compression", "Measurement" representing these regions are shown. As will be described later, the image of the screw 20 in the injection device image display column 31 (see Figure 2 ) is set such that when the actual screw 20 (see Figure 2 ) retracts within the heating cylinder 19 during measurement, it is shown as retracting dynamically in synchronization with the screw position. At this time, each region and the words "Supply", "Compression", "Measurement" representing the region also retract together.

[0060] The temperature setting and display column 32 is a column for displaying the set temperature and the measured temperature of each of the heater groups H1, H2,... NH2 and the hopper mounting portion HP. That is, for each of the heater groups H1, H2,... NH2 and the hopper mounting portion HP, there is displayed: a set temperature input column 35, 35,... for inputting the set temperature; a measured temperature display column 36, 36,... for displaying the measured temperature; and a temperature flag 37 for graphically showing the deviation of the measured temperature from the set temperature.

[0061] Further, in each of the heater groups H1, H2,... for the heaters 25, 25... belonging to the corresponding heater groups H1, H2,... (see Figure 2), status lights 38, 38, ... indicating the ON / OFF state are shown. For example, if it is in the ON state, it is shown in green, and if it is in the OFF state, it is shown in gray, white, etc. It should be noted that the heater 25 is not provided at the hopper mounting portion HP. Although not shown, a temperature-regulating medium (e.g., cold water) is supplied / stopped to the hopper mounting portion HP through ON / OFF control. Therefore, the status lights 38 for the hopper mounting portion HP are set to show whether the medium is being supplied or stopped. The status lights 38, 38... are not essential components, and the status lights may not be provided.

[0062] In the temperature setting and display column 32, the respective display widths of the heater groups H1, H2, ..., NH2 and the hopper mounting portion HP are adjusted according to the corresponding physical heater groups H1, H2, ..., NH2 (see Figure 2 ), and the length in the axial direction of the hopper mounting portion HP. That is, for the heater groups H1, H2 that are relatively long in the axial direction, the display width is longer, and for the heater groups NH1, NH2 that are relatively short in the axial direction, the display width is shorter. Therefore, the user can set the set temperature while knowing the length in the axial direction of the actual heater groups H1, H2, …, NH2. It should be noted that the display columns of the respective heater groups H1, H2, ... in the temperature setting and display column 32 may not be adjusted according to the length in the axial direction of the physical heater groups H1, H2, ..., NH2 (see Figure 2 ). For example, the horizontal width can be set at equal intervals.

[0063] When a molding cycle is carried out in the injection molding machine 1 (see Figure 1 ), as the metering progresses in the metering process, the screw 20 (see Figure 2 ) gradually retracts. At this time, in the injection device image display column 31 of the cylinder temperature setting and display screen 30 (see Figure 3A ) according to the first embodiment, the image of the screw 20 (see Figure 2 ) shown also retracts as shown by the reference numeral 39 in Figure 3B . At this time, in the injection device image display column 31, each region and the words "supply", "compression", and "metering" indicating the regions are also shown to retract dynamically. When reaching the metering completion position set as the molding condition, the image of the screw 20 (see Figure 2 ) shown in the injection device image display column 31 also stops.

[0064] When the screw position at the end of metering is set as the screw most-retracted position as the molding condition, the screw 20 (see Figure 2 ) retracts until the screw most-retracted position in the metering process. Thus, asFigure 3C As shown by the reference numeral 40 in the injection device image display bar 31, the image of the screw 20 (see Figure 2 ) is shown as retracting until the screw reaches its most retracted position. Thus, the cylinder temperature setting and display screen 30 according to the first embodiment enable an intuitive understanding of the relationship between the screw 20 (see Figure 2 ) and the heater groups H1, H2,..., NH2 when the screw 20 (see

[0065] [Comparative Example]

[0066] To understand the function of the cylinder temperature setting and display screen 30 according to the first embodiment, the cylinder temperature setting and display screen 80 according to the comparative example will be described. In the cylinder temperature setting and display screen 80 according to the comparative example, a contour line 81 schematically showing the heating cylinder 19 (see Figure 4 ) is depicted. Above this contour line 81, the characters of the identifiers "H1", "H2",..., "NH2" representing the heater groups H1, H2,..., NH2 (see Figure 2 ) are displayed. In addition, the identifier "HP" representing the hopper mounting portion HP is also displayed. However, these "NH2", "NH1",..., "HP" are arranged at equal intervals. In the contour line 81, temperature setting input fields 84, 84,... for each heater group NH2,... and measured temperature display fields 85, 85,... and temperature indicators 86, 86,... are displayed corresponding to the identifiers "NH2", "NH1",..., "H1", "HP". Figure 2 ) are shown.

[0067] In the cylinder temperature setting and display screen 80 according to the comparative example, when temperature setting is performed for each heater group H1, H2,..., NH2 (see Figure 2 ) and the hopper mounting portion HP, the relationship of the lengths in the axial direction of each heater group H1, H2,..., NH2 is not clear. In addition, the positional relationship between the heater groups H1, H2,..., NH2 and the screw 20 (see Figure 2 ) is also not clear. The user needs to imagine the lengths in the axial direction of the heater groups H1, H2,..., NH2 and the positional relationship with the screw 20 (see Figure 2 ) while performing temperature setting, which requires proficiency.

[0068] [Second Embodiment]

[0069] <Injection Device>

[0070] A description will be given of the second embodiment. Although the injection molding machine according to the second embodiment is a large-sized injection molding machine, it is configured in the same manner as the injection molding machine 1 according to the first embodiment shown in Figure 1 . Therefore, the description of the configuration will be omitted. Figure 5 An injection device 3A of the injection molding machine according to the second embodiment is shown. In the injection device 3A according to the second embodiment, the same reference numerals are given to the components that are the same as those of the injection device 3 (see Figure 2 ) according to the first embodiment, and the description thereof is omitted.

[0071] In the second embodiment, the heating cylinder 19 is provided with a larger number of heaters 25, 25,... than in the first embodiment (see Figure 2 ). These heaters 25, 25,... are divided into heater groups H1, H2,..., H5, NH1, NH2. In the second embodiment, a heater group H5 is added compared to the first embodiment. The same applies to the temperature sensors S1, S2,...; a temperature sensor S5 is added in the second embodiment. Further, in the second embodiment, not only the thread 27 is formed on the screw 20, but also sub-threads 27a are formed in the compression region Z2 and the metering region Z3. That is, a so-called barrier-type thread is formed in the compression region Z2 and the metering region Z3.

[0072] <Cylinder Temperature Setting and Display Screen>

[0073] Figure 6A and Figure 6B A cylinder temperature setting and display screen 30A according to the second embodiment is shown. The same reference numerals are given to the components that are the same as those of the cylinder temperature setting and display screen 30 (see Figure 3A ) according to the first embodiment, and the description thereof is omitted. In the second embodiment, a set temperature input column 35, a measured temperature display column 36, and a temperature indicator 37 for the heater group H5 are added. In the cylinder temperature setting and display screen 30A according to the second embodiment, the image of the injection device 3A (see Figure 5 ) shown in the injection device image display column 31 does not show each region and the identifiers "supply", "compression", and "metering" indicating these regions. That is, the image is simplified. And the screw 20 (see Figure 5 ) shown in the injection device image display column 31 is displayed as a screw including a barrier-type thread in a part thereof.

[0074] In the cylinder temperature setting and display screen 30A according to the second embodiment, when the screw 20 (see Figure 5 ) retracts during the metering process, as shown in Figure 6BAs shown by reference numeral 42 in the drawings, the image of the screw 20 is also shown to move backward dynamically.

[0075] [First Variant of the First Embodiment]

[0076] The first and second embodiments can be variously modified. Figure 7 A modified screen of the cylinder temperature setting and display screen 30 according to the first embodiment (see Figure 3A ) is shown. That is, an injection device display screen 45 according to the first variant of the first embodiment is shown. The injection device display screen 45 is provided with an injection device image display column 31, but is not provided with a temperature setting and display column 32 (see Figure 3A ). That is, it is a screen that only shows the image of the injection device 3 (see Figure 2 ). In addition, in the image of the injection device 3 shown in the injection device image display column 31, the respective regions and the identifiers "supply", "compression", and "metering" indicating these regions are not shown. That is, the image is simplified.

[0077] In the injection device display screen 45, the image of the screw 20 (see Figure 2 ) is not set to be displayed moving dynamically. The image of the screw 20 is set such that the image is switched and displayed for two screw positions, namely, the metering completion position and the most forward position set in the molding conditions.

[0078] [Second Variant of the First Embodiment]

[0079] Figure 8 A cylinder temperature setting and display screen 30' according to the second variant of the first embodiment, which is a modification of the cylinder temperature setting and display screen 30 according to the first embodiment (see Figure 3A ), is shown. The cylinder temperature setting and display screen 30' according to the second variant differs from the cylinder temperature setting and display screen 30 according to the first embodiment (see Figure 3A ) in the following two points.

[0080] First, the difference is that the image of the injection device 3 (see Figure 2 ) displayed in the injection device image display column 31 is shown such that the scale for the axial direction and the scale for the orthogonal direction are different. Specifically, the scale for the axial direction is shown to be significantly reduced compared to the orthogonal direction. Second, the difference is that for the heating cylinder 19 (see Figure 2 ) shown in the injection device image display column 31, the internal regions are shown in different colors for distinction as indicated by reference numerals 48, 49, and 50. Similarly, in the cylinder temperature setting and display screen 30' according to the second variant, when the screw 20 (see Figure 2)When actually retracting during the metering process, the image of the screw 20 is also displayed as dynamically retracting in the injection device image display column 31.

[0081] As described above, the invention of the present inventor has been specifically described based on the embodiments. However, the present invention is not limited to the embodiments already described, and various modifications can be made without departing from the gist thereof. The multiple examples described above can also be implemented by appropriately combining them.
