Description

  The present invention relates to a feed passage structure for a flanged shaft-like component.

  Japanese Patent No. 4025912 discloses an apparatus that solves a problem when flanges of flanged bolts overlap. The solution here is to pull the earliest bolt upwards and stop there, so that the flange of the subsequent bolt does not interfere with the flange of the earliest.

Japanese Patent No. 4025912

  The technique described in the above-mentioned patent document is focused on how to deal with the flange of the first bolt and the flange of the second bolt. However, there is no description of the problem when bolts are fed in a daisy chain.

  When feeding a flanged shaft-shaped part, particularly when the flange is thin, it is difficult to feed the flange without overlapping the flanges. When the flange thickness is thin, a method of setting the height dimension of the flange passing portion slightly larger than the flange thickness dimension can be considered in order to avoid overlapping of the front and rear flanges. However, with such a measure, the space dimension between the flange surface and the inner wall of the flange passing portion becomes minute, so if impurities such as iron scraps get stuck in the space, the flange cannot be slid. This hinders smooth parts feeding.

  In addition, using a supply hose to allow a plurality of parts to reach the target location with overlapping flanges will feed two or three parts in a single supply hose with overlapping flanges. As a result, the inner wall of the supply hose is bitten or the mass becomes excessive, and smooth feeding becomes impossible. Therefore, when feeding to the target location, it is necessary to send it in an independent single component state.

  Furthermore, it is necessary to set the passage shape so that the flanged shaft-shaped component is not caught in the connection portion of the feeding passage.

  The present invention has been provided to solve the above-mentioned problems, and smoothly feeds the flanges of the flanged shaft-like parts in an overlapping state, and at the same time, reliably transitions to the subsequent feeding hose. An object of the present invention is to provide a component feed passage structure that can be used.

  According to the first aspect of the present invention, a flanged shaft-shaped part is an object to be fed, and the feeding path of the shaft-shaped part is formed in a metal path member, and the feeding path is shaped like a shaft. It is formed by the flange passing part through which the flange of the part passes and the shaft passing part through which the shaft part of the shaft-like part passes, and the space height in the flange thickness direction of the flange passing part smoothly passes through the overlapping flanges. Cutting out the first shaft-shaped component of the component row in which the flanges are arranged in a state where the flanges overlap in the middle of the feeding passage, independently of one shaft-shaped component. A low flange passage portion provided with a mechanism, wherein the space height of the flange passage portion on the downstream side of the cut-out mechanism is gradually reduced to be slightly higher than the flange thickness of an independent shaft-shaped part. Open at the end of A flexible plastic supply hose that can be bent is formed, and a hose passage having the same shape as the supply passage is formed in the supply hose, and the supply passage and the hose passage match. In this state, a supply hose is connected to the passage member.

  The space height in the flange thickness direction of the flange passing portion is set to a height that allows the overlapping flanges to pass smoothly. That is, the space height of the flange passing portion is set to be larger than the thickness dimension of the overlapping flange, and an extra height dimension is added in addition to the thickness dimension of the overlapping flange. Become. Therefore, the flange passing portion can be smoothly passed with the flanges overlapping.

  A cutting mechanism is provided in the middle of the feeding path to feed out the earliest shaft-shaped component of the component row in which the flanges are arranged in an overlapping state, independently from one shaft-shaped component, and the cutting mechanism A low flange passage portion, which is slightly lower than the flange thickness of an independent shaft-like part, is opened at the end of the passage member by gradually reducing the space height of the flange passage portion on the downstream side. It is formed in a state. For this reason, an independent shaft-shaped component without overlapping flanges is cut off from the component row of shaft-shaped components with overlapping flanges, and the height dimension of the flange passing portion is gradually reduced to one flange thickness dimension. Is reduced to a slightly higher dimension. That is, in terms of shape, the flange passing portion shifts to the low flange passing portion. Accordingly, the single shaft-like component reaches the low flange passage portion through which only one of the flange thicknesses can pass, and the transfer without the occurrence of overlapping flanges is possible.

  A flexible synthetic resin supply hose that can be bent is provided, a hose passage having the same cross-sectional shape as the supply passage is formed in the supply hose, and the supply passage and the hose passage are aligned with each other. A supply hose is connected to the member. Therefore, the shaft-shaped component is transferred from the passage member to the supply hose without the occurrence of overlapping flanges, thereby enabling smooth component feeding. In addition, by setting the flange passage portion in the hose passage like the low flange passage portion, the phenomenon that the flange repeatedly swings up and down is avoided, and the flange portion is caught on the inner wall of the hose passage. Nothing happens. Further, when the shaft-like component is conveyed by air injection, the gap between the flange and the flange passing portion has a small size, so that the amount of jet air leaking from this gap can be reduced, and the air High conveyance power can be maintained. In connection with this, the conveyance speed in a supply hose can be raised and it can be used for productivity improvement.

  According to a second aspect of the present invention, the height of the flange passage portion of the hose passage is larger than the height of the low flange passage portion of the feed passage. It is.

  Since the size relationship between the height dimension of the low flange passage part of the feed passage and the height dimension of the flange passage part of the hose passage is set as described above, the shaft-shaped part that moves from the passage member side to the hose passage The flange surely enters the flange passage part of the hose passage. In such a joint between both flange passing portions where the space dimension in the flange thickness direction is reduced, the flange must smoothly transition. If both flange passing parts are slightly displaced in the thickness direction of the flange, the flange will get caught on the end face and corners on the supply hose side, making smooth flange transition impossible. By adding the magnitude relationship, the above-described catch does not occur.

  Since the low flange passage part on the side of the passage member is made of metal, the space height can be manufactured with high accuracy. On the other hand, since the supply hose is made of synthetic resin, it is deformed at the connection part of the passage member and the supply hose, or is subjected to thermal expansion and contraction due to seasonal changes and factory environment, so that the space height dimension of the flange passing part Becomes an abnormal dimension. Therefore, it becomes difficult to closely match the low flange passage portion of the passage member and the flange passage portion of the supply hose, and deformation or joining displacement occurs on the supply hose side at the joint portion. Due to these factors, it is easy for hooks at the flange passing part to occur on the supply hose side, but the space height of the flange passing part on the synthetic resin side is made larger than the space height of the low flange passing part on the metal side. There is always a smooth flange transition.

  Next, a mode for carrying out the component feed passage structure of the present invention will be described.

  1 to 9 show a first embodiment of the present invention.

  First, the flanged shaft-like component will be described.

  There are various shapes of the shaft-shaped component 1 with a flange which is a target in this embodiment. An example thereof will be described with reference to FIG. The thing of the figure (A) is a shaft-shaped component with an iron flange by which the circular flange 3 was integrally provided near the upper side of the shaft part 2 with a circular cross section. 1B is an iron projection bolt in which a circular flange 5 is integrally provided on a shaft portion 4 with a male screw cut, and a welding projection 6 is provided at the center of the flange 5. Is formed.

  In this embodiment, the flanged shaft-shaped component 1 shown in FIG. The dimensions of the parts 1 are as follows: the diameter of the shaft 2 is 6.5 mm, the length of the shaft 2 is 18 mm on the lower side of the flange 3, 6 mm on the upper side, and the diameter and thickness of the flange are 17.5 mm and 1.2 mm, respectively. It is.

  Next, the parts supply passage structure will be described as a whole.

  As shown in FIGS. 1 and 2, an elongate passage member 9 is joined to an upper portion of a column 8 standing from a base 7 of the component supply device by welding or the like. The passage member 9 is connected to a delivery rail 10 of a parts feeder (not shown) installed on the base 7 and is inclined so that the traveling direction of the parts is lowered. The passage member 9 is made of metal and is made of stainless steel.

  The component 1 is transferred in a suspended state with the flange 3 supported. FIG. 3 shows this hanging state, and the BB cross section of FIG. A feeding passage 11 is formed in the elongated passage member 9. A flange passage portion 12 through which the flange 3 passes and a shaft passage portion 13 through which the shaft portion 2 passes are formed in the feeding passage 11. The shaft passage part 13 is divided into a part that allows the lower side to pass through the flange 3 and a part that allows the upper side to pass through the flange 3. A long and narrow cover plate 14 is connected to the upper surface of the passage member 9 in a state of covering the left and right sides of the flange passage portion 12 with bolts or the like, and a space between the left and right cover plates 14 is connected to the upper shaft passage portion 13. Has been. The flange 3 is in contact with the corner formed by the bottom surface of the flange passage portion 12 and the inner surface in the vertical direction of the shaft passage portion 13, so that the shaft-like component 1 is suspended.

  The width dimension of the flange passage portion 12 is set to be slightly larger than the diameter of the flange 3, and the height dimension of the flange passage portion 12 viewed substantially in the flange thickness direction, that is, the space height H1 is an overlapping flange. The thickness dimension is set to be larger than 3. That is, a margin for smooth transfer is added to the dimensions of the two flanges. Here, since the passage member 9 is inclined, the shaft-like component 1 tries to take a vertical posture, so that the left end of the flange 3 is placed on the bottom surface of the flange passage portion 12 as shown in FIG. The right end of the flange 3 is in contact with the ceiling surface of the flange passing portion 12 (the lower surface of the cover plate 14). The delivery rail 10 also has a passage shape having a cover plate 14. The space height H1 varies depending on the inclination angle of the passage member 9, but in the range of 30 to 45 degrees that is a normal inclination angle, the space height is 2.5 to 3 sheets. Is set.

  On the downstream side of the passage member 9, an operation unit 16 having a cut-out mechanism 20 and an air injection port, which will be described later, is disposed. The operating part 16 is a base member 17 which is fixed on the passage member 9 by bolting instead of the cover plate 14, and a passage groove 18 is formed for performing the same function as the upper shaft passage part 13. It is. One end of the supply hose 19 is connected to the downstream side of the operation unit 16, and the other end reaches the supply target location of the shaft-like component 1. The base member 17 is also made of metal such as stainless steel.

  Next, the clipping mechanism will be described.

  The function of the cut-out mechanism 20 is to send the first shaft-shaped component 1 in the component row aligned with the flange 3 in an overlapped state independently to one shaft-shaped component 1. It is arranged in the middle. As the structure of the cut-out mechanism 20, various types such as those using an electromagnet and those using an advancing / retracting type regulation pin can be adopted. Here, it is the latter one.

  The air cylinder 21 is fixed to the upper surface of the base member 17, and the piston rod operates as the first restricting member 22. This first restricting member 22 enters the front side of the earliest shaft-like component 1 of the component row aligned with the flange 3 being overlapped, and prohibits the advancement of the component row that attempts to slide down the slope. Yes. On the other hand, the air cylinder 23 is fixed to the lateral surface of the passage member 9, and the piston rod operates as the second restricting member 24. The second restricting member 24 enters the front side of the second shaft-like component 1 in the component row aligned with the flange 3 being overlapped, and prohibits the second and subsequent component rows from moving forward. . Since the air cylinder 21 and the air cylinder 23 are mounted at the above-described locations, the piston rod that forms the first restricting member 22 and the piston rod that forms the second restricting member 24 are fed from different directions at right angles. Advances and retracts into the supply passage 11

  An air passage 25 is provided in the base member 17, and the jet air from the jet port 26 at the tip of the base member 17 causes the earliest shaft-like component 1 to move initially. For this purpose, the blast air from the blast port 26 is blown to the upper shaft portion 2 of the earliest shaft-like component 1. Further, in order to feed the independent shaft-shaped component 1a to the target location, an air passage 27 is provided in the passage member 9, and the sprayed air from the injection port 28 is blown to the shaft-shaped component 1a. . The air hose 29 is connected to the air passage 25, and the air hose 30 is connected to the air passage 27. Note that the air passage 27 and the injection port 28 are illustrated by a two-dot chain line in FIG. 4 and a chain line in FIG.

  FIG. 4 shows a state in which both the first restricting member 22 and the second restricting member 24 have advanced, and when the first restricting member 22 is retracted, the upper shaft portion 2 of the earliest shaft-like component 1 is shown. Initial injection is performed from the injection port 26, and the flange overlap is released and one is in an independent state. This independent shaft-like part is denoted by reference numeral 1a. Next, when the first restricting member 22 returns to the advanced position and then the second restricting member 24 moves backward, the entire part row slides down the feeding passage 11 and is received by the waiting first restricting member 22. It is done. Thereafter, the second restricting member 24 advances again and receives the second shaft-shaped component 1. The independent shaft-like component 1a is preliminarily transferred by air injection from the injection port 26, and is stopped slightly downstream from the injection port 28. Main injection is performed from the injection port 28 to the stopped shaft-shaped component 1a, and the shaft-shaped component 1a is fed to a target location at high speed. Alternatively, at the stage where the independent shaft-shaped component 1a is moving due to the preliminary injection from the injection port 26 and the inclination, the main injection is made from the injection port 28 to the shaft-shaped component 1a, and the shaft-shaped component 1a is moved at high speed It is sent to the destination.

  Next, the low flange passage portion will be described.

  The space height H1 of the flange passage portion 12 on the downstream side of the cutting mechanism 20 is gradually reduced by the inclined portion 31, and the space height H2 is set slightly higher than the flange thickness of the independent shaft-shaped part 1a. The passage portion where the space height is lowered is a low flange passage portion, which is indicated by reference numeral 12a. The low flange passage portion 12 a opens at the end of the passage member 9 and communicates with the supply hose 19.

  In this embodiment, since the feed passage 11 is inclined, the parts row slides down. When this inclination angle is small or when there is no inclination, it is appropriate to apply a sending vibration to the passage member 9 so as to be a linear feeder.

  Next, the supply hose will be described.

  The supply hose 19 is made of a flexible synthetic resin that can be bent. It is desirable to use a urethane resin as the synthetic resin. A hose passage 33 having the same shape as the feeding passage 11 is formed in the supply hose 19. FIG. 7A is a cross section of the supply hose 19, and FIG. 7B is an end face of the supply hose 19. In addition, the length of the supply hose 19 from the channel | path member 9 to the target location is 5.3 mm.

  As shown in FIG. 7D, the height dimension H3 of the flange passage portion 12b in the hose passage 33 is larger than the height dimension H2 of the low flange passage portion 12a of the feeding passage 11. A deformation due to some external force or thermal expansion or contraction occurs on the supply hose 19 side made of synthetic resin, and a step or the like is likely to occur in the continuous portion of the low flange passage portion 12a and the flange passage portion 12b. Since the relationship of H3> H2 is set, the catch of the flange 3 can be avoided. In FIG. 7D, the dimensional difference is exaggerated for easy understanding of the relationship of H3> H2.

  The space dimension H3 in the hose passage 33 is as described above. In order to reduce the leakage of the supply air, the space 2 between the shaft portion 2 and the inner surface of the hose passage 33 is the same as the above. It is desirable to make the gap as narrow as possible.

  As shown in FIG. 5, joint protrusions 34 and 35 are formed at the ends of the passage member 9 and the base member 17, and the positions of these protrusions are inserted into the insertion portion 36 formed at the end face of the supply hose. Yes. This inserted state is shown in FIG. In FIG. 5, the passage member 9 and the base member 17 are illustrated as being separated from each other, but both are brought into close contact as shown in FIG. 4 and integrated with a bolt or the like.

  In order to prevent the joint protrusions 34, 35 inserted into the insertion part 36 of the supply hose 19 from coming off, a U-shaped connection fitting 37 opened downward is used. A support plate 38 is welded to the lower surface of the passage member 9, and the joint protrusions 34 and 35 are inserted into the insertion portion 36 in a state where the supply hose 19 is placed on the support plate 38. In this state, the supply hose 19 is accommodated in the connection fitting 37, and the connection fitting 37 is fixed to the support plate 38 with bolts. Reference numeral 39 in FIG. 8 denotes four bolt insertion holes, and reference numeral 40 in FIGS. 5 and 8 denotes four screw holes into which bolts are screwed.

  It should be noted that an electric motor that performs forward / backward output can be employed instead of the various air cylinders.

  Operations such as the advancing / retreating operation and air injection of the first restricting member and the second restricting member described above can be easily performed by a generally adopted control method. A predetermined operation can be ensured by combining an air switching valve that operates with a signal from the control device or the sequence circuit, a sensor that emits a signal at a predetermined position of the air cylinder, and transmits the signal to the control device.

  The operational effects of the first embodiment described above are as follows.

  The space height H1 in the flange thickness direction of the flange passage portion 12 is set to a height that allows the overlapping flanges 3 to pass smoothly. That is, the space height H1 of the flange passing portion 12 is set to be larger than the thickness dimension of the overlapping flange 3, and an extra height dimension is added in addition to the thickness dimension of the overlapping flange 3. Will be. Therefore, it is possible to smoothly pass through the flange passing portion 12 while the flange 3 is overlapped.

  A cutout mechanism 20 is provided in the middle of the feed passage 11 to feed the earliest shaft-shaped component 1 in the component row in which the flanges 3 are overlapped in an independent state to one shaft-shaped component 1a. The low flange passage portion 12a is formed by gradually reducing the space height H1 of the flange passage portion 12 on the downstream side of the cutting mechanism 20 to be slightly higher than the flange thickness of the independent shaft-like component 1a. The passage member 9 is formed in an open state. For this reason, the independent shaft-shaped component 1a without overlapping flanges is separated from the component row of the shaft-shaped components 1 where the flanges 3 overlap, and the height dimension of the flange passage portion 12 gradually decreases to one. Reduced to a dimension slightly higher than the flange thickness dimension. That is, in terms of shape, the flange passage portion 12 is shifted to the low flange passage portion 12a. Therefore, the single shaft-like component 1a reaches the low flange passage portion 12a through which only one flange thickness can pass, and the transfer without the occurrence of flange overlap is possible.

  A flexible synthetic resin supply hose 19 that can be bent is provided, and a hose passage 33 having the same cross-sectional shape as the supply passage 11 is formed in the supply hose 19, and the supply passage 11 and the hose passage 33 are formed. A supply hose 19 is connected to the passage member 9 and the base member 17 in a matched state. Therefore, the shaft-like component 1a is transferred from the passage member 9 to the supply hose 19 in a state where no flange overlap occurs, and smooth component feeding is possible. Further, by setting the dimensions of the flange passage portion 12b in the hose passage 33 like the low flange passage portion 12a, a phenomenon in which the flange 3 repeatedly swings up and down is avoided, and the flange portion is hose passage. It won't catch on the inner wall. Further, when the shaft-like component 1a is conveyed by air injection, the gap between the flange 3 and the flange passage portion 12b has a small size, so that the amount of jet air leaking from the gap can be reduced. Therefore, the air conveying force can be maintained high. In connection with this, the conveyance speed in the supply hose 19 can be raised and it can be used for productivity improvement.

  The piston rod of the air cylinder 21 that forms the first restricting member 22 and the piston rod of the air cylinder 23 that forms the second restricting member 24 are advanced and retracted from the direction perpendicular to each other into the feed passage 11. The air cylinder 21 is attached to the upper surface of the base member 16, and the air cylinder 23 is attached to the lateral side surface of the passage member 9. Therefore, even when the component interval is narrow as in the flanged shaft-like component 1, the first restricting member 22 and the second restricting member 24 can be arranged close to each other.

  The height dimension H3 of the flange passage portion 12b of the hose passage 33 is larger than the height dimension H2 of the low flange passage portion 12a of the feed passage 11.

  Since the magnitude relationship between the height dimension H2 of the low flange passage portion 12a of the feed passage 11 and the height dimension H3 of the flange passage portion 12b of the hose passage 33 is set as described above, the hose from the passage member 9 side is set. The flange 3 of the shaft-shaped part 1 a that moves to the passage 33 surely enters the flange passage portion 12 b of the hose passage 33. In such a joint between the flange passing portions 12a and 12b in which the space dimension in the flange thickness direction is reduced, the flange 3 must smoothly move. If both the flange passing portions 12a and 12b are slightly displaced in the flange thickness direction, the flange 3 is caught on the end face or corner portion on the supply hose 19 side, and smooth flange transition becomes impossible. By providing the above-described magnitude relationship, the above-described catch does not occur.

  Since the synthetic resin supply hose 19 is connected to the metal member forming the feed passage 11, deformation or misalignment in the connecting portion is likely to occur on the synthetic resin supply hose 19 side. . Due to such factors, a catch at the flange passing portion is likely to occur on the supply hose 19 side, but the space height H3 of the flange passing portion 12b on the synthetic resin side is set to the space height of the low flange passing portion 12a on the metal side. Since it is larger than H2, a smooth flange transition is always obtained.

  As described above, according to the component feed passage structure of the present invention, the flanges of the flanged shaft-like components can be smoothly fed in an overlapping state, and at the same time, the transition to the subsequent feed hose can be reliably performed. it can. Therefore, it can be used in a wide range of industrial fields, such as an automobile body assembly process and a home appliance sheet metal assembly process.
