Description

  The present invention relates to a bolt supply apparatus, and more particularly to an apparatus for supplying bolts that have been aligned and conveyed to a predetermined arrangement position.

  As is well known, many bolts are used in the manufacturing process of an automobile engine. For example, the cam cap is mounted on the cylinder head. First, the cam cap is placed on the cylinder head, the bolt is inserted into the bolt insertion hole of the cam cap, and then the inserted bolt is tightened. The cam cap is fixed to the cylinder head. At this time, it is very troublesome and troublesome for the operator to take out the bolts loaded in a disorderly orientation in the bolt box one by one and insert them into the bolt insertion holes of the cam cap. . Therefore, after aligning and feeding the bolts that have been aligned and transported to a position corresponding to the bolt insertion hole of the cam cap placed on the cylinder head using a dedicated array supply device, a plurality of bolts in the array state are supplied. There is a need for means for transferring the bolts to the bolt insertion holes in a lump.

  As this type of arrangement supply apparatus, for example, a delivery apparatus described in Patent Document 1 has been proposed. This device receives the bolts fed by the feeding means by dropping them in a fixed posture one by one, receives the bolts that further fall freely from the cutting device in a fixed posture, and is defined A holding unit that positions and holds the holding unit; and a conveying unit that conveys the holding unit to a predetermined take-out position (array position). Then, the plurality of bolts that have reached the holding means after repeated free fall are transported (supplied) to a predetermined array position by the transport means, and then the plurality of bolts that are supplied and arrayed are collectively held by the robot arm. It can be transferred to the fastening position.

JP 2008-143687 A

  As described above, in the delivery device (array supply device) described in Patent Document 1, both the delivery of bolts from the feeding means to the cutting means and the delivery of bolts from the cutting means to the holding means are both bolts. Is done by free-falling. However, depending on the type of bolt, there is a type (form) in which the posture tends to collapse due to free fall, and there is also a type that tends to vary in the form of the bolt and the position of the center of gravity. In this case, there arises a problem that it is difficult to supply a stable array.

  In view of the above circumstances, the problem to be solved by the present invention is to stably supply and supply bolts regardless of the type of bolts.

  The solution to the above problem is achieved by the bolt supply device according to the present invention. That is, this apparatus is an apparatus for supplying bolts that have been aligned and transported from the aligning and transporting section to a predetermined array position, and a plurality of notch-shaped bolt receiving sections are provided at locations corresponding to the array position. It is provided, and is arranged on the outlet side of the aligning / conveying unit, and is unloaded from the aligning / conveying unit, which allows the receiving unit to move between the predetermined receiving position and the arranging position by rotating. A relay part provided with an intermediate receiving part capable of receiving a bolt, and an extruded part that allows the extruded bolt to slide to be transferred to the receiving part in the receiving position by extruding the bolt received in the intermediate receiving part. Characterized by points provided.

  As described above, in the present invention, the intermediate receiving unit receives the bolts that have been aligned and transported from the aligning and transporting unit, and the bolts received by the intermediate receiving unit are pushed out by the pushing unit, and the extruded bolts are slid. As a result, the bolts that are notched are transferred to the receiving part, so that the bolts that have been aligned and conveyed can be transferred to the receiving part without the free fall of the bolts whose posture is likely to be unstable. . Therefore, the bolts that have been aligned and conveyed can be reliably supplied to a predetermined arrangement position without being affected by the form of the bolts or individual quality.

  Further, the bolt supply device according to the present invention may be provided with two or more receiving positions, and in that case, the intermediate receiving unit can receive the bolts carried out from the alignment transport unit, and The relay part may be rotatable so that the bolt can be transferred between the receiving part in any receiving position.

  In the case of using the rotation arrangement portion provided with the bolt receiving portion having the notch shape as described above, the formation position of the reception portion in the rotation arrangement portion corresponds to the final bolt arrangement position. For this reason, the number and position of the receiving portions are important. For example, in the fastening operation of the cam cap to the cylinder head mentioned above as an example, depending on the number of cylinders, when four receiving portions are provided for one rotating arrangement portion, the bolts are inserted into the bolt insertion holes described above. If the position is in a position corresponding to the apex of the square in a plan view, the receiving unit is set every 90 degrees, and the rotation array unit is rotated by 90 degrees, so that a plurality (four) are always set at the same position. The receiving part can be stopped. In such an arrangement position, the intermediate receiving portion is provided with one transfer passage in a direction in which the bolt received in the intermediate receiving portion can be transferred between the intermediate receiving portion and the receiving portion in the receiving position. It is enough to connect the receiving part to the receiving part. However, when the actual bolt insertion position is not at the apex of the square in a plan view, the formation position of the receiving portion in the rotation arrangement portion is set accordingly, and the rotation phase of the rotation arrangement portion is individually set. Since it becomes necessary to slightly shift each receiving part, rotation control becomes complicated. In this type of supply device, such control should be avoided in view of the fact that it is required to supply a large number of bolts quickly and stably to the arrangement position.

  Here, in the present invention, as described above, since the relay portion provided with the intermediate receiving portion is configured to be rotatable according to the receiving position, the receiving portions are arranged at intervals of 90 degrees on the rotating arrangement portion. Even if it is not, the bolt received in the intermediate receiving portion can be surely sent out toward the corresponding receiving position. Also, in this case, it is only necessary to change the direction of the intermediate receiving part (notch direction) and the pushing direction of the bolt by the pushing part according to the receiving position, so the transfer operation from the intermediate receiving part to the receiving part is sufficient. Smooth and compact. Therefore, it is possible to reduce the size of the apparatus.

  In the bolt supply device according to the present invention, both the receiving portion and the intermediate receiving portion have a notched groove shape, and the head portion can be supported in a state where the shaft portion of the bolt is suspended, and the pushing portion is the head of the bolt. You may drive in the direction which extrudes a part in a fixed direction.

  By comprising as mentioned above, the volt | bolt extruded from the intermediate | middle receiving part can be moved along the direction which a shaft part can advance with the extrusion force received in the head part. That is, even if the pushing force received from the pushing portion is not directed to the receiving position at that time, the shaft portion of the bolt moves along the side surface of the notch groove constituting the intermediate receiving portion, and the bolt is in the receiving position. Can be sent to the receiving part. Therefore, it is sufficient for the push-out portion to be a mechanism that can be driven (stroked) in one direction, and thereby the entire bolt supply device including the push-out portion can be further reduced in size.

  In addition, the bolt supply device according to the present invention may include a bolt raising unit that raises the bolt received in the receiving unit with respect to the rotating arrangement unit. In this case, a collective holding unit that collectively holds a plurality of bolts raised by the bolt raising means may be provided.

  As described above, by further including the bolt raising means, all the bolts received in the plurality of receiving portions can be moved to above the rotating arrangement portion at a time. Therefore, for example, it is possible to attach or detach the upper part of the rotating array part, and further includes a collective holding part that collectively holds a plurality of bolts raised by the bolt raising means, so that the array is supplied to a predetermined array position. A plurality of bolts can be transferred to the mounting position (tightening position) of the bolts while holding the arrangement state in a lump. Thereby, the transfer operation | work from a rotation arrangement | sequence part to an actual attachment position can be performed smoothly and with few man-hours.

  As described above, according to the bolt supply device of the present invention, bolts can be stably arranged and supplied regardless of the type of bolt.

The rotation arrangement | positioning part 17 provided with multiple 16 and the extrusion part 18 which extrudes the volt | bolt B received in the intermediate | middle receiving part 14 are mainly provided.

  In this embodiment, the bolt supply device 10 includes a bolt raising means 19 that raises the bolt B that is received in the receiving portion 16 with respect to the rotating arrangement portion 17, and a plurality of bolts that are raised by the bolt raising means 19. And a collective holding unit 20 that collectively holds B. Details of each component will be described below.

  The relay unit 15 is disposed on the exit side of the alignment conveyance unit 12, in this embodiment, at a position adjacent to the outlet 21 a of the carry-out path 21 provided in the alignment conveyance unit 12 as shown in FIG. 3. The relay portion 15 has a disc shape, and is provided with an intermediate receiving portion 14 having a notch shape from the outer peripheral edge to the center. The relay portion 15 rotates around its central axis (vertical axis), thereby communicating the opening (first opening portion 14a) on the notch start side of the intermediate receiving portion 14 with the outlet 21a of the carry-out path 21. The first opening portion 14a can communicate with an opening portion (second opening portion 16a) on the notch start side of the receiving portion 16 described later (FIGS. 4 and 5). Specifically, when the receiving unit 16 is in a first stop position (receiving position) P1, which will be described later, from the state shown in FIG. 3 (the direction in which it can communicate with the outlet 21a of the carry-out path 21), the relay unit 15 Is rotated clockwise by an angle θ1, and when the receiving unit 16 is in a second stop position (receiving position) P2 described later, the relay unit 15 is controlled to rotate clockwise by an angle θ2. Is done. At this time, the rotation angles θ1 and θ2 of the relay unit 15 are θ1> 90 ° and θ2 <90 °, respectively.

  In this embodiment, the carry-out path 21 is formed between the pair of support plates 22, and the pair of support plates 22 is disposed so as to be inclined downward from the alignment transport unit 12 toward the array supply unit 13. Therefore, the unloading path 21 of the bolt B formed between the pair of support plates 22 is also inclined downward from the aligning and conveying unit 12 toward the array supplying unit 13. A plurality of bolts B (see FIG. 1) fed in are supplied toward the outlet 21a in a state of being sequentially aligned. The outlet 21a is provided with a stopper (not shown). The bolts B sequentially supplied toward the intermediate receiving portion 14 are locked immediately before the outlet 21a, whereby a plurality of intermediate receiving portions 14 are provided. This prevents the bolt B from being fed.

  The rotation arrangement unit 17 is disposed at a position adjacent to the relay unit 15, in this embodiment, on the inner side in the width direction of the relay unit 15 as shown in FIG. 2. Moreover, in this embodiment, the rotation arrangement | sequence part 17 comprises a disk shape, and it can be rotated to the surroundings of a vertical axis. In order to achieve the arrangement corresponding to the bolt insertion position into the cam cap described above, the outer peripheral edge of the rotation arrangement portion 17 has a notch shape at the arrangement position P corresponding to the insertion position in a plan view. A plurality of receiving portions 16 are formed. In this illustrated example, considering that four cam caps are arranged in parallel and two bolts B are used for each cam cap, the two rotation arrangement portions 17 are arranged in the width direction of the bolt supply device 10. Are arranged side by side (FIG. 2), and each receiving portion 16 is provided in each rotation arrangement portion 17.

  Here, as shown in FIG. 3, the arrangement positions P of the bolts B are not arranged at 90 ° intervals (that is, equally spaced in the circumferential direction), but are offset in different directions in the circumferential direction. Arranged in position. In this case, as shown in FIGS. 4 and 5, the receiving position of the bolt B by the receiving portion 16 is set at two different places (first receiving position P1 and second receiving position P2). That is, the rotation arrangement unit 17 is driven to rotate, and the rotation thereof is controlled so that the predetermined receiving unit 16 can be stopped at the above-described first or second receiving position P1, P2. In this case, the receiving positions P1, P2 of the receiving portions 16 are determined according to the arrangement of the final supply positions of the bolts B (for example, bolt insertion holes of the cam cap), and the notch angles θ3, θ4 of the receiving portions 16 are It is set according to the rotation angles θ1 and θ2 of the relay unit 15, respectively.

  As shown in FIG. 3, the extrusion portion 18 is disposed on the outer side in the width direction of the relay portion 15. Then, the bolt B received in the intermediate receiving portion 14 can be pushed out toward the receiving portion 16 located on the opposite side of the pushing portion 18 via the relay portion 15. In this embodiment, the pushing unit 18 is configured to be able to stroke on the relay unit 15 and the rotation array unit 17 along a virtual straight line connecting the rotation center of the relay unit 15 and the rotation center of the rotation array unit 17. . The stroke direction (extrusion direction) at this time is set to a direction that passes through the bolt receiving position of the intermediate receiving portion 14 and the rotation center of the rotating arrangement portion 17. That is, the stroke direction of the pushing portion 18 may be any direction that passes between the first receiving position P1 (FIG. 4) and the second receiving position P2 (FIG. 5). The stroke width at this time is such that the extrusion surface 23 can abut on the bolt B in the opening 16a of the receiving portion 16 at least from the position on the outer side in the width direction than the bolt B received in the intermediate receiving portion 14. Up to position. In the drawing, the position at which the pushing surface 23 can come into contact with the bolt B in the receiving portion 16 in a state stopped at the receiving positions P1 and P2 is the maximum stroke position of the pushing portion 18.

  As shown in FIG. 1, the bolt raising means 19 is disposed below the rotation arrangement portion 17. As shown in FIG. 9, the bolt raising means 19 includes a shaft support portion 19a for supporting the shaft portion Ba of the bolt B received in the receiving portion 16 from below, and a shaft support portion for supporting the shaft portion Ba. And an ascending drive unit (not shown) for ascending and driving the part 19a. In this embodiment, the shaft support portion 19a is disposed below the arrangement position P (see FIG. 2) of the bolts B and does not hinder the operation of receiving the bolts B into the receiving portions 16 at the receiving positions P1 and P2. Set to height. Then, as shown in FIG. 9, in a state where the collective holding unit 20 is placed above the rotating arrangement unit 17, the height of the head Bb of the bolt B can be supported by a pair of divided support units 24a and 24b described later. The shaft portion Ba can be raised. Of course, you may comprise so that the shaft part Ba may be received and supported simultaneously with the reception to the receiving part 16. FIG. Alternatively, an intermediate holding part that rotates integrally with the rotary arrangement part 17 and is provided with a holding part such as a notch is provided at an intermediate position in the axial direction between the shaft support part 19 a and the rotary arrangement part 17 and is received by the receiving part 16. A member for holding the shaft portion Ba may be disposed from the state until the head portion Bb is supported by the pair of split support portions 24a and 24b. Thereby, it is possible to raise the bolt B in a stable posture.

  As shown in FIGS. 6A and 6B, the collective holding unit 20 has a pair of divided support portions 24a and 24b that can be brought into contact with and separated from each other. The pair of divided support portions 24a and 24b are brought close to each other. In this state (FIG. 6A), it is possible to form an insertion hole 25 into which the shaft portion Ba of the bolt B can be inserted and an annular support end surface 26 that can support the head portion Bb. Further, in a state of being separated from each other (FIG. 6B), it is possible to form a gap 27 having a size capable of passing through the head portion Bb of the bolt B in the vertical direction (direction perpendicular to the contact / separation direction). In this embodiment, a plurality of pairs (four pairs in the figure) of split support portions 24a and 24b are provided according to the required array number and array position, and each pair of split support portions 24a and 24b includes: When approaching, a plurality (two in the drawing) of insertion holes 25 and support end surfaces 26 are provided. One of the divided support portions 24a (for example, the left side in FIG. 6B) is connected by a common connecting portion (one connecting portion 28a), and the other divided supporting portion 24b is another connecting portion. They are connected by (the other connecting portion 28b). Thereby, all the division | segmentation support parts 24a and 24b can be contacted / separated synchronously.

  In addition, an elastic member 29 is disposed between the other divided support portion 24b and the one divided support portion 24a on the outer periphery of the one connecting portion 28a and constituting another pair of divided support portions 24a and 24b. At the same time, grip portions 30 are provided at both end portions of one connecting portion 28a and one end portion of the other connecting portion 28b (FIG. 6B). Therefore, for example, by gripping these gripping portions 30 with both hands and bringing the two gripping portions 30 connected to the different connecting portions 28a, 28b close to each other, the pair of split support portions 24a, 24b can be accessed, By releasing the gripping state, the pair of split support portions 24a and 24b can be separated.

  In this case, a configuration for placing and operating the batch holding unit 20 is provided on the main body side of the array supply unit 13. Specifically, as shown in FIG. 10A, on the base surface 31 of the array supply unit 13, a first support unit 32 that supports a grip unit 30 (left side in the figure) that is gripped independently. And a second support portion 33 that supports both ends of the grip portion 30 (same as shown in the figure, right side) gripped so as to be close to each other, and a third support portion 34 that supports one of the connecting portions 28a. In addition, one movable side portion 35 constituting the second support portion 33 is configured to be movable up and down, for example, and when the movable side portion 35 is lowered and separated from the grip portion 30, the elastic member 29 is elastically restored. The pair of split support portions 24a and 24b can be brought close to each other.

  Hereinafter, the flow of the bolt arrangement supply process using the bolt supply device 10 having the above-described configuration will be described with reference to FIGS.

  First, a large number of bolts B are introduced into the hopper 11 of the aligning / conveying unit 12 so that a plurality of bolts B are conveyed in an aligned state on the unloading path 21 arranged outside the aligning / conveying unit 12 (see FIG. 1). At this time, the relay portion 15 is rotated so that the first opening 14 a of the intermediate receiving portion 14 and the outlet 21 a of the carry-out path 21 are in communication with each other. Thereby, the bolt B reaching the outlet 21a of the carry-out path 21 is in a state of being received by the intermediate receiving portion 14 through the first opening portion 14a. In this case, the transfer from the outlet 21a to the first opening 14a may be performed by inclining the carry-out path 21 and utilizing the transfer force due to the weight of the bolt B, but is appropriate below the outlet 21a. A force required to transfer from the outlet 21a to the first opening 14a may be applied to the bolt B by providing a simple feeding mechanism.

  When the bolt B is received in the intermediate receiving portion 14 in this way, the rotating arrangement portion 17 is then rotated, and the receiving portion 16 that has not yet received the bolt B is stopped at the corresponding receiving position P1 (P2). . For example, when the notch angle of the receiving portion 16 from which the bolt B is to be received is θ3, the receiving portion 16 is stopped at the corresponding first receiving position P1 and the relay portion 15 is bolted as shown in FIG. It is rotated clockwise by an angle θ1 from the position at the time of reception. And the extrusion part 18 is driven from this state, and the volt | bolt B is extruded. At this time, as shown in FIG. 8A, the pushing surface 23 of the pushing portion 18 abuts against the head portion Bb of the bolt B located above the relay portion 15 and heads toward the rotation center of the rotating arrangement portion 17. Push in part Bb. As a result, the shaft portion Ba of the bolt B moves along the side surface of the intermediate receiving portion 16 and the side surface of the receiving portion 16 both of which are notched, and as a result, the bolt B is pushed in by the pushing portion 18. It is extruded and slid in a direction different from the (stroke direction), and reaches the first receiving position P1 (see FIG. 8B).

  In this way, the above-described operation is repeated for the receiving portions 16 that have not yet received the bolts B, and the bolts B are received in all the receiving portions 16. If the notch angle of the receiving portion 16 from which the bolt B is to be received is θ4, the receiving portion 16 is stopped at the second receiving position P2 and the relay portion 15 is received as shown in FIG. Operations other than the point of rotating clockwise from the current position by an angle θ2 are the same as described above.

  As described above, the collective holding unit 20 is placed above the rotating arrangement unit 17 until the operation of receiving the bolt B into the receiving unit 16 is completed. Specifically, as shown in FIG. 2 and FIG. 10A, a plurality of support parts (first to third support parts 32 to 34) provided on the base surface 31 of the array supply part 13 are collectively displayed. The holding unit 20 is placed, and the batch holding unit 20 is positioned with respect to the rotation arrangement unit 17. At this time, as shown in FIG. 10 (a), the pair of gripping portions 30 located on the other end side in the width direction of the collective holding portion 20 are gripped and brought close to each other. The set of gripping portions 30 is attached to the second support portion 33. Thereby, a pair of division | segmentation support part 24a, 24b is positioned in the state mutually separated (in the state which formed the clearance gap 27).

  Then, the rotating arrangement portion 17 that receives the bolt B is rotated to stop the receiving portion 16 at the arrangement position P (FIG. 10A), and the shaft support portion 19a of the bolt raising means 19 is driven up. Then, all the bolts B in the receiving state are simultaneously raised (the state shown in FIGS. 9A to 9B). Then, after the head portion Bb of the bolt B passes through the gap 27 provided between the pair of divided support portions 24a and 24b, the movable side portion 35 of the second support portion 33 is lowered by, for example, lowering the movable side portion 35. The restraint in the width direction of the pair of grip portions 30 is released, and elastic recovery of the elastic member 29 in the compressed state is achieved (FIG. 10B). Thereby, a pair of division | segmentation support parts 24a and 24b move to the direction which mutually approaches (FIG.9 (b)). Accordingly, the bolt B is supported by the pair of divided support portions 24a and 24b vertically above the predetermined arrangement position P (FIGS. 10A and 10B). Then, from this state, by grasping the grip portion 30 and lifting the collective holding portion 20, all the bolts B received by the receiving portion 16 are lifted integrally with the collective holding portion 20. Therefore, by placing this on the bolt insertion hole of the cam cap, all the bolts B are inserted into the bolt insertion holes.

  As described above, in the present invention, the intermediate receiving portion 14 receives the bolt B which has been aligned and transported from the carry-out path 21, and the bolt B received by the intermediate receiving portion 14 is pushed out by the pushing portion 18 to be extruded. Since the bolt B is slid in a state where the head portion Bb is supported, the bolt B is transferred to the receiving portion 16 having a notch shape. The bolts B that have been aligned and conveyed can be delivered to the receiving portion 16 in a stable posture. Therefore, the bolt B that has been aligned and conveyed can be reliably supplied to the predetermined arrangement position P without being affected by the form of the bolt B or individual quality.

  Moreover, in this embodiment, since the rotation angle of the relay part 15 provided with the intermediate receiving part 14 can be adjusted according to the receiving position P1 (P2), the receiving part 16 becomes the rotating arrangement part 17 as shown in the figure. Even if it is not possible to dispose them at intervals of 90 degrees above, the bolt B received by the intermediate receiving portion 14 can be reliably sent out toward the corresponding receiving position P1 (P2). Further, in this case, it is sufficient to change the direction (notch direction) of the intermediate receiving portion 14 and the direction in which the bolt is pushed out by the pushing portion 18 according to the receiving position P1 (P2). The delivery operation to the receiving unit 16 can be performed smoothly and compactly. Therefore, it is possible to reduce the size of the apparatus.

  In particular, in this embodiment, both the receiving portion 16 and the intermediate receiving portion 14 are formed as notched grooves, the head portion Bb can be supported in a state where the shaft portion Ba of the bolt B is suspended, and the pushing portion 18 is Since the head portion Bb of B is driven in a direction to push it in a certain direction, the shaft portion Ba can be advanced by the pushing force received by the head portion Bb with the bolt B pushed out from the intermediate receiving portion 14. It can be moved along any direction. That is, the shaft portion Ba of the bolt B moves along the side surface of the notch groove constituting the intermediate receiving portion 14 even if the pushing force received from the pushing portion 18 does not face the receiving position P1 (P2) at that time. Then, the bolt B can be sent to the receiving portion 16 at the receiving position P1 (P2). Therefore, the extruding unit 18 may be a mechanism that can be driven (stroked) in one direction, whereby the entire bolt supply device 10 including the extruding unit 18 can be further reduced in size.

  Further, in this embodiment, the intermediate receiving portion 14 is provided by providing a notch in the disc-shaped relay portion 15, and the disc-shaped rotational arrangement portion 17 is also provided at a position in contact with the relay portion 15. Therefore, it is possible to smoothly transfer the bolts B without being caught while allowing them to rotate smoothly.

  More specifically, the rotation of the relay portion 15 and the rotation arrangement portion 17 is controlled so that the side surface of the intermediate receiving portion 14 having a notch groove shape and the side surface of the receiving portion 16 are continuous. The shaft portion Ba moves along the side surfaces of the continuous relay portion 15 and the rotation arrangement portion 17. Therefore, the bolt B can be delivered more smoothly and reliably.

  Further, as in this embodiment, the two carry-out paths 21 are arranged in parallel, the relay unit 15 is arranged in front of each carry-out path 21, and is orthogonal to the conveying direction of the bolt B by the carry-out path 21. In the case where two (or three or more) rotation arrangement portions 17 are arranged by providing the rotation arrangement portion 17 in the direction, that is, adjacent to the inner side in the width direction of the relay portion 15, Miniaturization is possible.
