Abstract

PROBLEM TO BE SOLVED: To provide a simple and inexpensive component aligning device capable of uniforming components fed in a plurality of kinds of postures to a fixed posture.SOLUTION: Components 12 randomly fed in two kinds of postures, i.e., a spine reference posture and prone reverse posture are placed on a rotary arm 32 and rotated around an axis S. Until the inclination angles (equal to a rotational angle of a rotary arm 32) of the components 12 reach a sorting angle θ, the components are engaged with positioning projections 26 and restricted from sliding and falling on the rotary arm 32. On the basis of a difference in a gravitational center position between the components 12 in two types of postures, in the case of the reference posture, the components are slid to fall on the rotary arm 32 while keeping the reference posture when the sorting angle θ is exceeded. In the reverse posture, opening side ends C2 of the components 12 are caught in the tips of the positioning projections 26 to roll and fall on the rotary arm 32 (refer to (b) and (c)) before the sorting angle θ is exceeded, and then displaced to the spine reference posture.

  2. Description of the Related Art A reversing device for reversing a U-shaped part or the like by a reversing mechanism is known. The reversing device described in Patent Document 1 is an example, and includes an inclined conveyor and a reversing mechanism, and can pass the components in their postures or can be reversed 180 °.

JP 11-292258 A

  However, since such a conventional reversing device passes through in the same posture or inverts 180 ° regardless of the component feeding posture, when a component with a different posture is randomly supplied, the posture is constant. In order to align with the above attitude, a device for detecting the supply attitude of the components is required separately. Further, since a tilting conveyor swinging device and a reversing mechanism are required, the entire device is complicated, large, and expensive.

  The present invention has been made against the background of the above circumstances, and the purpose of the present invention is to provide a simple and inexpensive part capable of aligning parts supplied in a plurality of kinds of postures in a predetermined posture. It is to provide an alignment device.

  In order to achieve such an object, the first invention is a parts alignment device for aligning parts supplied to a receiving position in a plurality of postures with a predetermined reference posture, wherein (a) a horizontal direction component is A rotating arm that is rotated around the axis S and has the component supplied to the receiving position placed thereon and rotated around the axis S, and (b) protrudes upward in the vicinity of the rotating arm. The component slides on the rotating arm until the tilt angle of the component which is placed and placed on the rotating arm and rotated about the axis S reaches a predetermined sorting angle θ. (C) based on the difference in the center of gravity position of the component in the plurality of types of postures, and when the component is in the reference posture, the inclination angle is the sorting angle θ. If the part exceeds In this case, the component is caught on the sliding regulation member before the inclination angle exceeds the sorting angle θ. It falls down and is displaced to the reference posture.

  According to a second aspect of the present invention, in the component aligning device according to the first aspect, (a) the component is a longitudinal member having a U-shaped cross section, the longitudinal direction is substantially parallel to the axis S, and the U-shaped opening side is upward. (B) In addition to being supplied to the receiving position in the reference posture, the parts are supplied to the receiving position in the inverted posture of the high center of gravity with the opening side facing downward. It is characterized by being.

  According to a third aspect of the present invention, in the component aligning device of the first or second aspect of the invention, (a) a carry-in chute arranged in a posture inclined at a predetermined angle with respect to a horizontal plane and sliding the component down to the receiving position; b) a discharge chute that is disposed in a posture inclined at a predetermined angle with respect to a horizontal plane, and that slides and discharges a component that is aligned with the reference posture by the rotating arm, and (c) the sliding regulation member Is integrally provided at the tip of the carry-in chute and has a function of positioning the component at the receiving position.

  According to a fourth aspect of the present invention, in the component aligning device according to any one of the first to third aspects, (a) in addition to the rotating arm, the rotating arm is provided at a predetermined angle on the front side in the rotating direction. And (b) the component that is placed on the rotating arm and lifted and is slid down or tumbled on the rotating arm, It is received by the preceding arm.

  According to a fifth aspect of the present invention, in the component aligning device of the fourth aspect of the present invention, an inclined guide is provided between the rotating arm and the preceding arm so as to obliquely connect intermediate portions of the arms. It is characterized in that it is received by the preceding arm from the rotating arm through the inclined guide.

  In such a component aligning device, components supplied to the receiving position in a plurality of kinds of postures are placed on the rotating arm and rotated around the axis S, and the inclination angle of the component is set to the sorting angle θ. Until it reaches, the sliding-down regulating member regulates that the part slides on the rotating arm. Then, based on the difference in the center of gravity position of the parts of a plurality of postures, when the part is in the reference posture, the part is referred to by being disengaged from the sliding regulation member beyond the sorting angle θ. Although it is slid down while maintaining the posture, if it is not the reference posture, the component is caught by the sliding-down regulating member before the sorting angle θ is exceeded, and falls on the rotating arm and displaced to the reference posture. Thereby, all the parts supplied to the receiving position in a plurality of types of postures are aligned with a predetermined reference posture.

  In that case, the component aligning device of the present invention changes the posture so that the component is lifted by the rotating arm and rotates around the axis S, and the sliding of the component is regulated to a predetermined sorting angle θ by the sliding regulating member. By simply doing this, the posture of the component is automatically aligned with the reference posture based on the difference in the center of gravity position, so that the apparatus is simple and inexpensive.

  The second invention is a case where the posture of the long U-shaped part is aligned with the reference posture, and the rotation arm of the component supplied to the receiving position in the reference posture with the low center of gravity with the opening side facing upwards exceeds the sorting angle θ. However, the parts supplied to the receiving position in the reversing posture of the high center of gravity with the opening side facing downward are dropped before the rotating arm exceeds the sorting angle θ and displaced to the reference posture. As a result, all the components are aligned with a low center of gravity reference posture with the opening side facing upward.

  The third invention has a carry-in chute for sliding the component down to the receiving position, and a discharge chute for sliding the component aligned in the reference posture by the rotating arm and discharging it, and the slide-down regulating member is integrated with the tip of the carry-in chute It is provided with a function to position the parts at the receiving position, so the device is simpler than when using a loading / unloading device that requires a power source or separately installing a slide-down restricting member. And at a low cost.

  According to a fourth aspect of the present invention, when the preceding arm is provided on the front side in the rotational direction of the rotating arm, the parts lifted by the rotating arm and slid down or dropped are appropriately received in the reference posture by being received by the preceding arm. Aligned.

  In the fifth aspect of the invention, an inclined guide is provided between the rotating arm and the preceding arm, and the component passes from the rotating arm onto the inclined guide and is received by the preceding arm. The behavior of the parts until they are received by is stabilized and more appropriately aligned with the reference posture.

It is a schematic front view explaining the structure of the components alignment apparatus which is one Example of this invention. It is the schematic plan view which looked at the components alignment apparatus of FIG. 1 from upper direction. It is a perspective view which shows an example of the components aligned by the reference attitude | position by the components alignment apparatus of FIG. FIG. 4 is an enlarged cross-sectional view taken along the line IV-IV in FIG. 3, and is a view showing the position of the center of gravity O in a reference posture with the opening side facing upward. FIG. 5 is a diagram illustrating the position of the center of gravity O in the case where the component in FIG. 4 is in an inverted posture with the opening side facing downward. FIG. 2 is a diagram for explaining a sorting angle θ at which a rotating arm exceeds a positioning protrusion and a component is allowed to slide down in the component aligning apparatus of FIG. 1. In the component alignment apparatus of FIG. 1, it is a figure explaining the case where the components supplied to the receiving position with the reference | standard posture by the carrying-in chute are delivered to a discharge chute with the same attitude | position. In the component alignment apparatus of FIG. 1, it is a figure explaining the case where the components supplied to the receiving position by the carry-in chute in the reverse posture are reversed to the reference posture and delivered to the discharge chute. It is a figure explaining the other Example of this invention, and is the figure which looked at the rotary body from the axial center S direction, and is a case where the inclination guide is each provided between the some rotation arms.

  The component aligning device of the present invention is, for example, in the case where parts are randomly supplied in two postures of a reference posture and a reversed posture in which the center of gravity is rotated about 180 ° with respect to the reference posture. Only the parts are inverted by about 180 ° to be the reference posture. The component is, for example, a U-shaped (U-shaped) long member having a shallow cross section and can be reversed to a direction perpendicular to the longitudinal direction and displaced to a reference posture. The present invention can also be applied to an apparatus for aligning other cross-sectional parts having different positions of the center of gravity depending on a plurality of postures when being supplied to the receiving position, such as an L-shaped cross section. As the reference posture, a posture that is relatively difficult to fall due to a posture change caused by rotation around the axis S is determined among a plurality of postures, for example, a posture having a low center of gravity position is determined.

  There may be only one rotating arm that is rotated around the axis S, and one component can be obtained by rotating in a certain direction around the axis S or swinging (reciprocatingly rotating) within a predetermined angular range. They can be lifted up and down or slid down or fall down to align with a certain standard posture. For example, a plurality of rotating arms may be provided at equal angular intervals, and continuously rotated in a constant direction around the axis S, and the components may be lifted one by one by the rotating arms and aligned with the reference posture. In that case, for example, it is desirable that the preceding rotary arm function as the preceding arm of the fourth invention so that the parts are received by the preceding arm in a state where the parts are aligned in the reference posture, and the size of the sorting angle θ is desirable. For example, it is appropriate to provide three rotating arms at intervals of 120 °, four rotating arms at intervals of 90 °, or five rotating arms at intervals of 72 °. For example, the leading arm is provided with a stopper that protrudes in a direction opposite to the rotation direction, and is configured to receive a component by the stopper.

  The rotating arm is provided so as to extend straight in a direction perpendicular to the axis S, for example. If the posture can be changed so that the component supplied to the receiving position is lifted and rotated around the axis S, Various modes are possible, such as bending in the middle. When the rotating arm extends straight in a direction perpendicular to the axis S, the angle of the rotating arm and the inclination angle of the component are the same, and the rotating arm exceeds the sorting angle θ, thereby The engagement is released and the part is allowed to slide down. In the case where the parts are long and long in the direction parallel to the axis S, a plurality of the rotating arms are provided, for example, at a predetermined interval in the direction of the axis S. A gap such as a slit is provided to allow the rotation of the rotating arm. In the third invention, a carry-in chute and a discharge chute inclined from the horizontal plane are provided as a carry-in / carry-out device, but it is also possible to use a belt conveyor, a roller conveyor, or the like on which components are mounted and conveyed by a driving force such as an electric motor. is there. These conveyors can be arranged horizontally, but can also be arranged with a downward inclination or an upward inclination with respect to the horizontal plane. As the carry-in / carry-out device, various modes such as gripping a part with a robot hand or the like and carrying it into a receiving position or carrying it out from a predetermined delivery position are possible.

  The sliding-down restricting member is integrally provided at the tip of the carry-in chute, for example, as in the third invention, but can be arranged in the vicinity of the rotating arm separately from the carry-in chute. This sliding regulation member is engaged with the part to prevent sliding until the inclination angle of the part whose posture is changed with the rotation of the rotary arm reaches the sorting angle θ, but the inclination angle of the part is the sorting angle θ. When the rotating arm rotates to exceed the upper limit, the rotating arm becomes higher than the sliding-down restricting member, and the reference posture component placed on the rotating arm is allowed to slide down on the rotating arm. .

  The inclined guide according to the fifth aspect connects the rotary arm and the leading arm obliquely, and a linear member or a concave arc member is preferably used. In carrying out other inventions, such an inclined guide is not always necessary, and can be directly transferred from the rotary arm to the unloading device such as the discharge chute without sliding the leading arm.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic front view for explaining the configuration of a component aligning apparatus 10 according to an embodiment of the present invention, and FIG. 2 is a schematic plan view seen from above of FIG. 3 is a perspective view showing an example of a component 12 aligned in a reference posture by the component aligning apparatus 10 of FIG. 1, and FIG. 4 is a cross-sectional view showing an enlarged IV-IV section in FIG. FIG. 5 shows a prone inverted posture in which the opening side of the component 12 faces downward. In this embodiment, the component 12 is a center pillar inner panel of an automobile, and is a U-shaped (U-shaped) longitudinal member having a relatively shallow cross section. The components are randomly supplied to the component aligning device 10 in the two inverted postures of the prone position shown in FIG. 1, and the components 12 in the inverted posture are automatically reversed by about 180 ° and sent out so as to become the reference posture.

  4 and 5 both show a state in which the component 12 is stably placed on the horizontal plane F, and the center of gravity O is in a position biased toward the U-shaped back side. The gravity center angles α and β, which are inclination angles with respect to the horizontal plane F of the straight line connecting the downstream corner C1 or the opening-side end C2 and the gravity center O, have a relationship of α <β. In the inverted posture of the high center of gravity shown in FIG. 5, when the part 12 is tilted clockwise beyond (90 ° −β) with the opening side end C2 as a fulcrum, the center of gravity O becomes the opening side end (fulcrum). ) While the component 12 falls rightward after passing directly above C2, in the reference posture with a low center of gravity shown in FIG. 4, even if it is tilted beyond (90 ° -β) (90 ° -α) The component 12 will not fall down until it exceeds (). Therefore, as shown in FIG. 6, when the sorting angle θ is set within the range of (90 ° −β) <θ <(90 ° −α) and the component 12 is inclined by the sorting angle θ, the inverted posture is obtained. Only the part 12 rolls clockwise. The center-of-gravity angle γ of the new corner (fulcrum) C3 in the rollover state is smaller than the center-of-gravity angle β, but can be further rolled over and reversed to the reference posture with the momentum of rollover. When the sorting angle θ is larger than (90 ° −γ), the component 12 is reliably reversed to the reference posture. In this way, the component aligning device 10 reverses only the component 12 in the reversed posture by approximately 180 ° and aligns it with the reference posture based on the difference between the gravity center angle α in the reference posture and the gravity center angle β in the reversed posture. In this embodiment, the center-of-gravity angles α≈25 °, β≈55 °, γ≈50 °, and the sorting angle θ≈50 °.

  In FIG. 1, a component aligning device 10 includes a rotating body 20 that is rotatably disposed around a substantially horizontal axis S, a carry-in chute 22 that is disposed on the upstream side of the rotating body 20 in the transport direction D, and a rotation. A discharge chute 24 disposed on the downstream side of the body 20. The carry-in chute 22 and the discharge chute 24 are both arranged in a direction perpendicular to the axis S of the rotating body 20 in a plan view shown in FIG. The component 12 is slid down on the carry-in chute 22 and the discharge chute 24 in a posture in which the longitudinal direction is substantially parallel to the axis S. The parts 12 are stacked on a pallet in a posture in which the longitudinal direction is substantially parallel to the axis S and conveyed to the upstream side of the carry-in chute 22 and carried in the reference posture or the reversed posture by a workpiece take-out device (not shown) such as an electromagnet. 22 is transferred to the upstream side portion. The inclination angle of the carry-in chute 22 and the discharge chute 24 is substantially the same and is smaller than the above (90 ° −β), and the component 12 is in the reference posture or the reverse posture placed on the carry-in chute 22 or the discharge chute 24. It is slid down while maintaining. The carry-in chute 22 and the discharge chute 24 may be simple rod-shaped members, but a number of rotatable rollers are arranged on the sliding surface in parallel with the axis S, and the component 12 slides down by the free rotation of the rollers. You can do it. If the component 12 can be slid down, the inclination angle of the carry-in chute 22 and the discharge chute 24 can be set to the above (90 ° −β) or more, and even if the component 12 rolls down for the carry-in chute 22. good.

  A plurality (five in the embodiment) of the carry-in chute 22 and the discharge chute 24 are arranged at predetermined intervals in the direction of the axis S (vertical direction in FIG. 2), and a plurality of the longitudinal parts 12 are arranged in the longitudinal direction. It is designed to slide down in support of the location. A positioning projection 26 bent upward at a substantially right angle is provided at the tip of the carry-in chute 22, and the component 12 slid down on the carry-in chute 22 is stopped at a predetermined receiving position by the positioning projection 26. Then, it is positioned at the receiving position with the reference posture or the inverted posture (see (a) of FIG. 7 and FIG. 8). A take-out device (not shown) is disposed on the downstream side of the discharge chute 24, and the parts 12 aligned in the reference posture are conveyed to a subsequent process by a robot or the like.

  The rotating body 20 is integrally fixed to the rotating shaft 30 so as to extend straight from the rotating shaft 30 in a direction orthogonal to the shaft center S. The rotating shaft 30 is disposed concentrically with the shaft center S. The rotating shaft 30 is continuously rotated around the axis S in FIG. 1 clockwise by a driving motor 34 at a predetermined rotational speed. Four rotary arms 32 are provided radially around the rotary shaft 30 at intervals of 90 °, and a plurality of sets (five sets in the embodiment) are provided at predetermined intervals in the axis S direction. By being rotated clockwise around the axis S integrally with the rotary shaft 30, the component 12 supplied to the receiving position is rotated around the axis S so as to be placed and lifted upward. The plurality of sets of rotating arms 32 are located in the gap between the plurality of carry-in chutes 22 and discharge chutes 24 in a plan view shown in FIG. 2, and can rotate around the axis S without interfering with them.

  The length L1 of the rotary arm 32 (see FIG. 6) is such that the downstream end of the carry-in chute 22 and the upstream end of the discharge chute 24 span the length of the width 12 of the component 12 in the transport direction D. , Each is defined to overlap. Accordingly, the component 12 can be received at the receiving position at the downstream end portion of the carry-in chute 22 along with the rotation around the axis S, and the component 12 can be transferred to the delivery position at the upstream end portion of the discharge chute 24. The width dimension L2 of the component 12 is the larger one of the horizontal dimensions in FIGS. 4 and 5 and is overlapped by the width dimension L2 or more, so that the rotary arm 32 receives the component 12 at the receiving position. When it is lifted or delivered to the discharge chute 24, it can be reliably transferred without disturbing the posture of the part 12. Further, the tip of the positioning projection 26 is slightly bent toward the conveyance direction D side, and even when the side surface of the component 12 has irregularities, the component 12 is placed on the rotary arm 32 without engaging with the irregularities. To be lifted properly.

  The tilting posture of the component 12 placed on the rotating arm 32 is the same as the rotating angle around the axis S where the horizontal direction of the rotating arm 32 is 0 °. However, sliding and falling are regulated by the positioning projection 26. The positioning projection 26 also functions as a sliding-down restricting member, and the tip position protruding upward has reached a position that coincides with the sorting angle θ with the axis S as the center. It is located within the range indicated by. A one-dot chain line in FIG. 6 illustrates the positioning protrusion 26 with the axis S as a reference. Therefore, when the component 12 at the receiving position is in the reference posture, the sliding arm is prevented from sliding by engagement with the positioning protrusion 26 until the rotating arm 32 reaches the sorting angle θ as shown in FIG. When θ is exceeded, the engagement with the positioning protrusion 26 is released, and the rotary arm 32 is slid down toward the rotary shaft 30 while maintaining the reference posture. Then, the component 12 sliding down on the rotary arm 32 gets over the rotary shaft 30 as shown in FIG. 7C while maintaining the reference posture, and is received by the preceding rotary arm 32, as shown in FIG. Then, it is delivered to the discharge chute 24 with the standard posture. The diameter of the rotary shaft 30 is determined so that the component 12 can get over while maintaining the reference posture. Each rotary arm 32 also functions as a leading arm, and a stopper 36 that is bent at approximately 90 ° in the direction opposite to the rotation direction is integrally provided at the tip of the rotary arm 32, and the component 12 is transferred to the discharge chute 24. It comes to hold. In FIG. 2, the stopper 36 is omitted.

  On the other hand, when the component 12 at the receiving position is in the prone inverted posture, the center of gravity O is just above the tip of the positioning projection 26 before the rotating arm 32 exceeds the sorting angle θ as shown in FIG. Is passed, and the opening side end C2 is tumbled clockwise in a state where it is caught by the tip of the positioning projection 26. As a result of the fall, the component 12 is set to a reference posture on its back as shown in (c) and is received by the preceding rotary arm 32, and is delivered to the discharge chute 24 in the state of the reference posture as shown in (d). The length dimension L1 of each rotary arm 32, the diameter dimension of the rotary shaft 30, and further the sorting angle θ are such that the part 12 whose opening side end C2 is caught clockwise by the positioning projection 26 is turned down. It is determined as appropriate by experiments or the like so that it can be received by the preceding rotary arm 32 in the reference posture. As described above, the components 12 in the inverted posture are inverted by approximately 180 ° to be the reference posture, so that the postures of all the components 12 supplied from the carry-in chute 22 are aligned with the reference posture.

  In addition, on the carry-in chute 22, the component 12 is intermittently charged every ¼ rotation in synchronization with the rotation of the rotating body 20, and one component 12 is provided by each rotating arm 32 provided at 90 ° intervals. Each of them is aligned with the reference posture and continuously sent onto the discharge chute 24. FIG. 7 (c) shows a case where a part 12 in the reverse orientation is newly supplied to the receiving position following the part 12 in the reference orientation. This part 12 is shown in FIGS. 8 (a) to (d). Is reversed to the reference posture and transferred to the discharge chute 24. FIG. 8 (c) shows a case where a part 12 in the reference posture is newly supplied to the receiving position following the part 12 in the reversed posture, and this part 12 is shown in FIGS. 7 (a) to (d). Are delivered to the discharge chute 24 with the standard posture.

  As described above, in the component aligning apparatus 10 of the present embodiment, the U-shaped component 12 supplied to the receiving position by the carry-in chute 22 in the two postures of the low center of gravity reference posture and the high center of gravity reversed posture is as follows. It is placed on the rotating arm 32 and rotated around the axis S, but the positioning projection 26 until the inclination angle of the component 12 (same as the rotating angle of the rotating arm 32 in the embodiment) reaches the sorting angle θ. The sliding of the component 12 on the rotary arm 32 is restricted by the engagement with the. If the component 12 is in the reference posture based on the difference in the center of gravity position of the component 12 in two types of postures, the component 12 remains on the rotating arm 32 while maintaining the reference posture when the sorting angle θ is exceeded. However, in the case of the inverted posture, before the sorting angle θ is exceeded, the opening-side end C2 of the component 12 falls on the tip of the positioning projection 26 so as to fall down on the rotary arm 32, and the reference posture facing upward To be displaced. As a result, the parts 12 supplied to the receiving position in two types of postures are all aligned with a predetermined reference posture.

  In this case, the component aligning apparatus 10 of the present embodiment changes the posture so that the component 12 is lifted by the rotary arm 32 and rotates around the axis S, and the component is aligned up to the sorting angle θ determined in advance by the positioning projection 26. Since the posture of the component 12 is automatically aligned with the reference posture based on the difference in the center of gravity simply by restricting the sliding of the device 12, the apparatus is configured simply and inexpensively.

  In addition, the component aligning device 10 of the present embodiment includes a carry-in chute 22 that slides the component 12 to the receiving position, and a discharge chute 24 that slides and discharges the component 12 aligned in the reference posture by the rotating arm 32, The tip position of the positioning chute 26 that is integrally provided at the tip of the carry-in chute 22 and defines the receiving position of the component 12 functions as a slide-down restricting member. Compared with the case where the device is used or the sliding-down restricting member is separately provided, the device is simple and inexpensive.

  In addition, four rotary arms 32 are provided around the axis S at intervals of 90 °, and each rotary arm 32 also functions as a leading arm, and is lifted by any rotary arm 32 to slide or fall. The received parts 12 are received by the previous rotary arm 32 functioning as a preceding arm, so that they are appropriately aligned with the reference posture and delivered to the discharge chute 24.

  In the above-described embodiment, the component 12 lifted by the rotary arm 32 and slid down or dropped is received by the rotary arm 32 that has moved over the rotary shaft 30 and preceded, but like the rotary body 40 shown in FIG. You may provide the inclination guide 42 which connects the intermediate part of the adjacent rotation arm 32 diagonally. In this case, since the component 12 is received by the preceding rotating arm 32 from the rotating arm 32 through the inclined guide 42, the component 12 slides or falls from the rotating arm 32 and is received by the preceding rotating arm 32. Twelve behaviors are stable and more appropriately aligned with the reference posture. A position, a size, an inclination angle, and the like for providing the inclination guide 42 are appropriately determined by experiments or the like so that the reference posture is obtained in a state where the component 12 is received by the preceding rotary arm 32. In addition, although the linear inclination guide 42 is provided in FIG. 9, as shown with a dashed-dotted line, inclination guides, such as a concave arc shape, can also be used.

  As mentioned above, although the Example of this invention was described in detail based on drawing, this is an embodiment to the last, and this invention implements in the aspect which added various change and improvement based on the knowledge of those skilled in the art. Can do.
