Description

[Technical field]

[0001] The present invention relates to a fastener for fastening piping to a component of an industrial machine, an industrial machine, and an injection molding machine. [Background technology]

[0002] Industrial machines such as lathes, presses, and extruders are equipped with various pipes, such as pipes that supply hydraulic pressure to drive the equipment and pipes that supply media such as cooling water and hot water. These pipes are composed of multiple sections that combine metal pipes and flexible hoses that have flexibility. Metal pipes are used in sections where the pipes can be installed in a fixed manner and are fixed to a specified component, and flexible hoses are used in sections that are connected to moving parts of the industrial machines or external media supply devices.

[0003] For example, in the case of a vertical injection molding machine, which is a type of industrial machine, a safety cover is provided around the clamping device as described in Patent Document 1. A plurality of metal pipes constituting fixed sections of a plurality of pipings are fixed inside the safety cover. Joint members are provided at the upper and lower ends of the metal pipes, and flexible hoses are connected to the joint members, which are connected to the movable part or an external medium supply device.

[0004] [Patent Document 1] JP 2019-048414 A Summary of the Invention [Problem to be solved by the invention]

[0005] Metal pipes are fixed to components of industrial machines by a specific fixture, and the fixture is designed to fix a plurality of pipes together to the components so that the pipes do not get in the way of the industrial machine. However, there are problems to be solved with the fixture. Specifically, since the plurality of pipes are fixed to the components in a bundled state, it is not possible to adjust the position of only some of the pipes. To adjust the position, it is necessary to loosen the fixture, but when the fixture is loosened, the fastening of all the pipes becomes loose, and the positions of these pipes become unstable. In particular, in the case of a vertical injection molding machine, the plurality of pipes made of metal pipes are fixed to a safety cover so as to be vertical. Therefore, when the fixture is loosened, all the pipes fall at the same time due to their own weight. Therefore, in order to fix the pipes at a desired height, it is necessary for multiple workers to cooperate to support the pipes and fasten the fixture.

[0006] The present disclosure provides a fixture that allows for easy adjustment of the position of a pipe and fastening the pipe to a component member.

[0007] Other objects and novel features will become apparent from the description of this specification and the accompanying drawings. [Means for solving the problem]

[0008] A fastener according to the present disclosure for fastening a pipe to a component of an industrial machine is configured as follows. The fastener has a mounting surface and a back surface, which is the opposite surface, and one or more drilled holes are drilled perpendicular to and penetrating the mounting surface and back surface. One or more tapped holes with bottoms are drilled in the back surface of the fastener, and one or more pipe holding grooves for holding the pipe in the mounting surface are formed. The fastener is configured to be attached to a predetermined surface of a component having one or more tapped holes, or to the back surface of another fastener, as the mounting target surface. The fastener is configured so that, with one or more pipes placed in the pipe holding grooves, one or more bolts are inserted from the back surface into the drilled holes and tightened into the tapped holes in the mounting target surface. Effect of the Invention

[0009] The fixture of the present disclosure allows easy adjustment of the position of piping and fastening to a component. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Specific embodiments will be described in detail below with reference to the drawings. However, the present invention is not limited to the following embodiments. In order to clarify the description, the following description and drawings are appropriately simplified. In each drawing, the same elements are given the same reference numerals, and duplicated descriptions are omitted as necessary. In addition, hatching is omitted in some parts to avoid cluttering the drawings.

[0012] [First embodiment] <Injection molding machine> The fixing device according to the first embodiment, which will be described in detail later, is adapted to fix piping provided in an industrial machine to a component of the industrial machine, and can be used for any type of industrial machine. Here, an injection molding machine 1 according to the first embodiment, shown in FIG. 1, will be described as a representative example of an industrial machine. In this embodiment, the injection molding machine 1 is a so-called vertical injection molding machine. The injection molding machine 1 includes a toggle-type mold clamping device 2, an injection device 3, and a control device 4. The control device 4 is adapted to control the mold clamping device 2, the injection device 3, etc.

[0013] <Mold clamping device> The mold clamping device 2 includes a fixed platen 9 fixed to a bed 7, an upper movable platen 10 provided above the fixed platen 9, and a lower movable platen 11 provided within the bed 7. The upper movable platen 10 and the lower movable platen 11 are connected by three tie bars 12, 12, .... A toggle mechanism 14 is provided between the lower movable platen 11 and the fixed platen 9, and a turntable 15 is provided above the fixed platen 9. An upper mold 17 is provided on the upper movable platen 10, and a lower mold 18 is provided on the turntable 15. When the toggle mechanism 14 is driven, the upper mold 17 and the lower mold 18 are opened and closed.

[0014] <Injection device> The injection unit 3 is provided on the upper movable platen 10 of the mold clamping unit 2. The injection unit 3 includes a heating cylinder 19, a screw 20 provided in the heating cylinder 19, a screw driving unit 22, and an elevating unit 23 that raises and lowers the entire injection unit 3. Although not shown in Fig. 1, the heating cylinder 19 is provided with an injection nozzle at its tip, through which an injection material is injected.

[0015] <Safety cover> In the injection molding machine 1, a safety cover 5 is provided above the fixed platen 9 of the mold clamping unit 2. The safety cover 5 also covers the lower part of the injection unit 3 to ensure the safety of the operator. In Fig. 1, the safety cover 5 is only drawn on the so-called anti-operation side, that is, the rear side of the mold clamping unit 2 and the injection unit 3. However, in reality, safety covers are also provided on both sides of the mold clamping unit 2, and a safety door is provided in front of the mold clamping unit 2, that is, on the operation side, although this is not shown in Fig. 1.

[0016] <Piping> The injection molding machine 1 is also provided with a plurality of pipes 25, 25, .... The pipes 25, 25, ... are composed of metal pipes 26, 26, ... which are fixed sections, and flexible hoses 27, 27, ... which are connected to these metal pipes 26, 26, .... The fixed sections of the pipes 25, 25, i.e., the metal pipes 26, 26, ..., are fixed to the inside of the safety cover 5 by fixtures 30, 30 according to a first embodiment described next. Note that flexible hoses are also connected to the lower ends of the metal pipes 26, 26, and are connected to an external medium supply device, but these are not shown in FIG. 1.

[0017] <Fixing fixture> Fixtures 30, 30 according to the first embodiment are shown in Figures 2A and 2B. The fixture 30 shown in Figure 2A is a first type fixture 31, and the fixture 30 shown in Figure 2B is a second type fixture 32. Both the first type fixture 31 (see Figure 2A) and the second type fixture 32 (see Figure 2B) have mounting surfaces 35, 35 and rear surfaces 36, 36 which are the opposite surfaces. The mounting surfaces 35, 35 are surfaces for mounting to a component of an industrial machine, that is, a safety cover 5 (see Figure 1) in the case of the injection molding machine 1. The mounting surfaces 35, 35 of these fixtures 31, 32 each have two pipe holding grooves 38, 38, ... for holding the pipes 25 (see Figure 1).

[0018] Both the first type of fastener 31 (see FIG. 2A) and the second type of fastener 32 (see FIG. 2B) have drilled holes 39, 39, ... that are perpendicular to and penetrate the mounting surfaces 35, 35 and the back surfaces 36, 36. However, the positions and the number of the drilled holes are different between the first and second types. That is, in the first type of fastener 31 (see FIG. 2A), two drilled holes 39, 39 are drilled and positioned outside the two pipe holding grooves 38, 38. On the other hand, in the second type of fastener 32 (see FIG. 2B), one drilled hole 39 is drilled in the middle between the two pipe holding grooves 38, 38.

[0019] The first type of fastener 31 (see FIG. 2A) and the second type of fastener 32 (see FIG. 2B) have bottomed tapped holes 41, 41, ... on the back surface 36, but the positions and the number of the holes are different. That is, in the first type of fastener 31 (see FIG. 2A), one hole is drilled in the middle of the two drilled holes 39, 39, and in the second type of fastener 32 (see FIG. 2B), two holes are drilled at equal intervals from the one drilled hole 39. The first type of fastener 31 (see FIG. 2A) has one bottomed hole, i.e., a bolt head storage hole 42, which is aligned with the tapped hole 41 on the mounting surface 35. The second type of fastener 32 (see FIG. 2B) has two bolt head storage holes 42, 42, which are aligned with the two tapped holes 41, 41 on the mounting surface 35.

[0020] <How to fix the pipes> A method for fixing pipes 25, 25, i.e., metal pipes 26, 26 (see FIG. 1) using a fixture 30 according to the first embodiment will be described. As shown in FIG. 3A, tapped holes 44, 44 are drilled in a predetermined member constituting the safety cover 5, i.e., a safety cover side member 46. The fixture 30 is attached to this portion as the target mounting surface. First, two metal pipes 26, 26 are inserted into two pipe holding grooves 38, 38 of a first type of fixture 31. Then, two bolts 45, 45 are inserted into drilled holes 39, 39 from the back surface 36, and the fixture 30 is pressed against the safety cover side member 46.

[0021] When the bolts 45, 45 are tightened, the metal pipes 26, 26 can be fixed as shown in FIG. 3B. FIG. 3C is a side view showing the state in which the metal pipe 26 is fixed to the safety cover side member 46 by the two first type fasteners 31, 31 at the top and bottom. The lower end of the metal pipe 26 is provided with a ball valve 48, which is a joint member equipped with a valve. This ball valve 48 is elbow-shaped so that other piping, for example, a flexible hose, can be attached and detached from the side. To adjust the ball valve 48 to an appropriate vertical position, the bolts 45, 45 are slightly loosened and the height of the metal pipe 26 is adjusted. Once the height is adjusted to an appropriate position, the bolts 45, 45 are tightened. Since there are only two metal pipes 26 to be adjusted, the work can be easily performed by one worker. The installation of the first row is completed.

[0022] 3D, two new metal pipes 26, 26 are attached using a different type of fastener 30, i.e., a second type of fastener 32. That is, the two metal pipes 26, 26 are inserted into the two pipe holding grooves 38, 38 of the second type of fastener 32, and a bolt 45 is inserted into the drilled hole 39 from the back surface 36. The second type of fastener 32 is attached to the back surface 36 of the first row of fasteners 31 already attached to the safety cover side member 46, as the attachment target surface.

[0023] When the bolt 45 is tightened into the tapped hole 41, the second type of fastener 32 is fixed as shown in Fig. 3E. That is, two new metal pipes 26, 26 are fixed as the second row. At this time, the two bolts 45, 45 fixing the first type of fastener 31 in the first row are stored in the bolt head storage holes 42, 42 of the second type of fastener 32. Although there is only one bolt 45 fixing the second type of fastener 32, the heads of the mounting bolts 45, 45 in the first row are stored in the bolt head storage holes 42, 42, thereby preventing the second type of fastener 32 from shifting.

[0024] FIG. 3F shows how two second type fixtures 32, 32 are attached to the first type fixtures 31, 31 on the upper and lower sides with bolts 45, 45, and the metal pipes 26, 26, ... are fixed. When the two bolts 45, 45 that fix the second type fixtures 32, 32 are loosened, the newly fixed pipe 25 in the second row, that is, only the metal pipe 26 on the right side in the figure, can be raised or lowered. The height is adjusted appropriately and the bolts 45, 45 are tightened. At this time, since there are only two metal pipes 26 to be adjusted in position, the work can be easily performed by one worker.

[0025] Similarly, by alternately fixing the first type of fixture 31 and the second type of fixture 32, a plurality of pipes 25, 25, ..., i.e., a plurality of metal pipes 26, 26, ..., can be attached to the safety cover side member 46 in a plurality of rows as shown in Fig. 3G and Fig. 3H. The height of the metal pipes 26, 26, ... can be adjusted by loosening the bolts 45, 45 as shown in Fig. 3H, by adjusting the height of the metal pipes 26, 26, ..., which are the object of position adjustment, in the row at the right end, so that the work can be easily performed by one worker. In other words, even when the height of a plurality of pipes 25, 25, ..., for example, eight pipes, is adjusted and fixed to the safety cover side member 46 as shown in Fig. 3G and Fig. 3H, it is only necessary to adjust the height of one row, i.e., two pipes 25, 25, and fix them, so that the work can be easily performed.

[0026] [Comparative Example] As a comparative example, a fixture 100 in which it is difficult to adjust the height of the pipe will be described with reference to Figs. 4A and 4B. The fixtures 100, 100, ... according to the comparative example are of one type, as shown in Fig. 4A. The fixtures 100, 100, ... each have a mounting surface 101 and a back surface 102, and two pipe holding grooves 104, 104 are formed in the mounting surface 101. The fixtures 100, 100, ... each have three drilled holes 105, 105, ... penetrating from the mounting surface 101 to the back surface 102. For each of the four fixtures 100, 100, ..., two pipes 109, 109, ... are inserted into the pipe holding grooves 104, 104, and the fixtures are fixed together to the safety door side member 107 by three bolts 110, 110, .... FIG. 4B shows a state in which pipes 109, 109, . . . are fixed by four fixing devices 100, 100, .

[0027] As shown in FIG. 4B, the pipes 109, 109, ... are provided with ball valves 111, 111, ... at their respective lower ends. When adjusting the height of the ball valves 111, 111, ..., it is necessary to loosen the bolts 110, 110. However, when the bolts 110, 110 are loosened, all the pipes 109, 109, ... fall at the same time. In order to adjust the height, it is necessary for multiple workers to support the pipes 109, 109, ... and tighten the bolts 110, 110 after adjusting them to an appropriate height. The installation work of the pipes 109, 109 is not easy.

[0028] [Modification 1 of the first embodiment] The fixture 30 according to the first embodiment (see FIG. 3G) is configured to fix the pipes 25, 25, ... by two types of fixtures 31, 32, but this can be modified. FIG. 5 shows a state in which the pipes 25, 25, ... are fixed using not only the first type of fixture 31 and the second type of fixture 32, but also a third type of fixture 50 and a fourth type of fixture 51. The third type of fixture 50 has the same structure as the fixture 100 according to the comparative example described above (see FIG. 4A). That is, it has a mounting surface 35 and a back surface 36, and two pipe holding grooves 38, 38 are formed in the mounting surface 35, and three drilled holes 39, 39, ... are drilled through the mounting surface 35 to the back surface 36.

[0029] The first two pipes 25, 25 are fixed to the safety cover side member 46 as the first row by the third type of fastener 50. The first two pipes 25, 25 are fixed to the safety cover side member 46 by one bolt 45. When the first type of fastener 31 is attached to the rear surface 36 of the third type of fastener 50 as the attachment target surface, the first type of fastener 31 is attached by two long bolts 53, 53. The long bolts 53, 53 penetrate not only the second row of fasteners 31 but also the first row of fasteners 50 and are fastened to the tapped holes 44 of the safety cover side member 46. Therefore, the third type of fastener 50 in the first row and the first type of fastener 31 in the second row are firmly fixed. When the second type of fastener 32 is attached to the second row of first type of fastener 31, the second type of fastener 32 is attached to the fourth row of second type of fastener 32 in the third row in the same manner.

[0030] The fourth type of fastener 51 is provided in the fifth row. The fourth type of fastener 51 has a mounting surface 35 and a back surface 36. The mounting surface 35 has two pipe holding grooves 38, 38, two bolt head receiving holes 42, 42, and one drilled hole 39 penetrating the mounting surface 35 and the back surface 36. However, no tapped hole or the like is formed in the back surface 36 of the fourth type of fastener 51. This is because other fasteners 31, 32, ... cannot be attached to the back surface 36 of the fourth type of fastener 51. Therefore, the fourth type of fastener 51 has a smaller thickness, i.e., a smaller width from the mounting surface 35 to the back surface 36, compared to the other fasteners 31, 32, .... The fourth type of fastener 51 is fixed to the first type of fastener 31 by one bolt 45.

[0031] [Modification 2 of the first embodiment] <Height adjustment member> The fixture 30 according to the first embodiment (see Figs. 3G and 3H) allows height adjustment only for the last two pipes 25, 25 in the final row that are attached when attaching the pipes 25, 25. However, by using the first and second types of height adjustment members 60, 61 as shown in Figs. 6A and 6B, it is possible to simultaneously adjust the height of multiple rows of pipes 25, 25, ... by the same amount. The height adjustment members 60, 61 will now be described.

[0032] As shown in Fig. 6A, the first type of height adjustment member 60 is plate-shaped and has an attachment surface 63 and a back surface 64. Slots 66, 66 are formed at both ends of the first type of height adjustment member 60, and as will be described later, fixing bolts are inserted into the slots so that the first type of height adjustment member 60 is fixed to the attachment target member, for example, the safety cover 5 (see Fig. 1). Three tapped holes 67, 67, ... are formed in the back surface 64.

[0033] As shown in FIG. 6B, the second type height adjustment member 61 is composed of a pair of legs 69, 69 and a plate-shaped top 71 connecting the legs 69, 69. In the central space surrounded by the pair of legs 69, 69 and the top 71, a plurality of pipes are inserted, as will be described later. In other words, the second type height adjustment member 61 is configured to straddle a plurality of pipes by the pair of legs 69, 69. The pair of legs 69, 69 are each formed with mounting parts 72, 72 protruding outward, and the mounting parts 72, 72 are provided with elongated holes 74, 74. As will be described later, a fixing bolt is inserted into the elongated holes 74, 74, so that the second type height adjustment member 61 is fixed to a member to which it is to be attached. The top 71 is provided with three tapped holes 75, 75, . . .

[0034] <How to fix the pipes> A method for fixing the pipes 25, 25, ... using the first and second types of height adjustment members 60, 61 will be described. As shown in Fig. 6C, the first type of height adjustment member 60 is fixed to the safety cover side member 46. Specifically, fixing bolts 82, 82 are inserted into the elongated holes 66, 66 of the first type of height adjustment member 60 and tightened into tapped holes 83, 83 formed in the safety cover side member 46.

[0035] Next, for the third type of fastener 50 as the first row, two metal tubes 26, 26 are inserted and fixed to the back surface 64 of the first type of height adjustment member 60 with one bolt 45. For the first type of fastener 31 as the second row, two metal tubes 26, 26 are inserted and fixed to the third type of fastener 50 in the first row with two long bolts 53, 53. For the second type of fastener 32 as the third row, two metal tubes 26, 26 are inserted and fixed to the first type of fastener 31 in the second row with one bolt 45.

[0036] Next, as shown in Figures 6D and 6E, the second type of height adjustment member 61 is fixed to the safety cover side member 46 so as to straddle the first, second, and third rows of pipes 25, 25, .... Specifically, the fixing bolts 85, 85 are inserted into the elongated holes 74, 74 of the second type of height adjustment member 61 and tightened into the tapped holes 83, 83 formed in the safety cover side member 46. At this time, as shown in Figure 6E, the second type of height adjustment member 61 is provided at a higher position than the first type of height adjustment member 60.

[0037] The first type of fastener 31 is attached to the top 71 of this second type of height adjustment member 61 as the fourth row. That is, two metal tubes 26, 26 are inserted into the first type of fastener 31 and fixed to the top 71 of the second type of height adjustment member 61 with two bolts 45, 45. Next, the fourth type of fastener 51 is attached as the fifth row. That is, two metal tubes 26, 26 are inserted into the fourth type of fastener 51 and fixed to the first type of fastener 31 with one bolt 45.

[0038] When the pipes 25, 25, ... are fixed using the first and second types of height adjustment members 60, 61, the height of the pipes 25, 25, ... can be adjusted all at once. For example, as shown in FIG. 6E, when the fixing bolt 82 is loosened, the first type of height adjustment member 60 can be slid up and down by the length of the elongated hole 66. That is, the positions of the first, second, and third rows of pipes 25, 25, ... attached to the first type of height adjustment member 60 can be adjusted all at once in the vertical direction by the length of the elongated hole 66. Similarly, when the fixing bolt 85 is loosened, the second type of height adjustment member 61 can be slid up and down by the length of the elongated hole 74. That is, the positions of the fourth and fifth rows of pipes 25, 25, ... attached to the second type of height adjustment member 61 can be adjusted all at once in the vertical direction by the length of the elongated hole 74.

[0039] [Second embodiment] A fixing device 88 according to the second embodiment will be described with reference to Figures 7A and 7B. The fixing device 88 according to the second embodiment is also configured to attach pipes 25, 25 to the safety cover 5 of the injection molding machine 1 (see Figure 1) according to the first embodiment. The injection molding machine 1 and the safety cover 5 are configured similarly to those in the first embodiment, so descriptions thereof will be omitted.

[0040] <Fixing fixture> 7A, the fixture 88 according to the second embodiment is of one type and has a mounting surface 89 and a back surface 90 on the opposite side. The mounting surface 89 is formed with two piping storage recesses 92, 92 into which piping is inserted. Pipe holding members 93, 93 are inserted into the piping storage recesses 92, 92, and the pipe holding members 93, 93 are slidable by tightening bolts 94, 94. The fixture 88 according to the second embodiment has three drilled holes 96, 96, ... that are perpendicular to the mounting surface 89 and the back surface 90.

[0041] FIG. 7B shows a state in which the pipes 25, 25, ... are fixed in three rows of two pipes each using three fasteners 88, 88, ... according to the second embodiment. The three fasteners 88, 88, ... are attached by three common bolts 98, 98, ..., which are fastened to tapped holes 44, 44, ... provided in the safety cover side member 46.
