JP2000-72231 JP-A-3-26416 JP2002-37442

  The reversing devices described in Patent Documents 1 and 2 cannot easily cope with changes in the size or form of an article.

  Although the reversing device described in Patent Document 3 can cope with a change in the size and form of an article to some extent, the number of articles processed that can be reversed per unit time cannot be increased.

  On the other hand, there is a case where it is necessary to select whether to turn the article upside down or not, but the inversion devices described in Patent Documents 1 to 3 cannot cope with it. For example, when supplying a cap to a cap tightening machine, depending on the characteristics of the cap type and cap aligning machine, the upper and lower directions of the cap may be upward or downward. If you want. Also, in a processing machine capable of general-purpose work, when an article is supplied by an aligning device such as a parts feeder, the article is generally aligned so that the center of gravity side of the article is downward. I don't want to do it. In order to solve this, although there is a means of picking each one by a robot and directing it in a desired direction, since it is an individual process, its ability is naturally limited. Even a high-speed robot capable of processing 1 piece / second has a limit of 60 pieces / minute.

  An object of the present invention is to provide a selective inversion apparatus for an article, which can cope with whether or not the article is turned upside down.

  Another object of the present invention is to provide an article selective inversion device that can handle articles of various sizes and forms.

  Another object of the present invention is to provide a selective inversion apparatus for articles having high throughput.

  According to the first aspect of the present invention, the inclined article receiving portion is supported by the support frame, the inclination of the article receiving portion with respect to the support frame can be swung up and down with respect to the horizontal plane, and the turning means on which the support frame is mounted. Is a selective reversing device for an article that can be rotated 180 degrees around a horizontal axis.

Example 1
1 receives articles such as a trigger cap 1, a regular cap 2, a machine screw 3 and a pump cap 4 to be described later from an input chute 101 and flips them up and down or flips them up and down. The discharge chute 102 can be discharged as it is. The discharge chute 102 is positioned vertically below the input chute 101.

  As shown in FIGS. 1 to 5, the article selection reversing device 100 has a turning means 12 installed on a base plate 11 provided on a gantry 10, and an article receiving unit 13 is mounted on the turning means 12. The turning means 12 has a turning actuator 20 and a turning base 30. The article receiving unit 13 includes a support frame 40, an elevating actuator 50, and an article receiving unit 60.

  The article selection reversing device 100 supports the article receiving section 60 inclined to the article receiving unit 13 on the support frame 40, and the inclination angle of the article receiving section 60 with respect to the support frame 40 is raised and lowered on both sides with respect to the horizontal plane by the lifting actuator 50. That is, the turning base 30 of the turning means 12 on which the support frame 40 is mounted can be turned 180 degrees around the horizontal axis by the turning actuator 20. That is, the article receiving unit 13 includes a support frame 40, an article receiving section 60 that is pivotally supported by the support frame 40, and a lift actuator that is provided on the support frame 40 and moves up and down the base end of the article receiving section 60. 50. The turning means 12 includes a turning base 30 that holds the support frame 40 of the article receiving unit 13 and a turning actuator 20 that turns the turning base 30.

Hereinafter, a specific configuration of the article selection reversing device 100 will be described in detail.
In the article selection reversing device 100, a turning actuator 20 including a turning motor is attached to a base plate 11 on a gantry 10, and a turning shaft support unit in which a turning shaft 31 of the turning base 30 is attached to a turning shaft base plate 32 on the base plate 11. The drive gear 21 supported by 33 and fixed to the output shaft of the turning actuator 20 is engaged with the driven gear 22 fixed to the turning shaft 31. The turning shaft 31 (horizontal axis) of the turning base 30 is rotated by driving the turning actuator 20. The motor of the swing actuator 20 is preferably capable of high-speed rotation and high acceleration / deceleration. A notch provided at a specific position in the circumferential direction of the swing end point support plate 34 fixed to the swing shaft 31 of the swing base 30 is formed on the swing shaft base plate 32. By detecting by the attached turning end point detection sensor 35, the original position of the turning shaft 31 and the reverse position which forms 180 degrees from the original position are detected, and each of these positions is determined as the stop position of the turning shaft 31. If the motor of the swing actuator 20 is a servo motor or a stepping motor and the motor itself can detect the output shaft, and hence the position of the swing shaft 31, the swing end point support plate 34 and the swing end point detection sensor 35 are unnecessary. .

  In the article selection reversing device 100, the support frame 40 of the article receiving unit 13 is mounted on the turning base 30 of the turning means 12. The support frame 40 has left and right support frame arms 42 projecting from a support frame plate 41, and the support frame plate 41 is fitted and fixed to the recess of the swivel base 30, and is provided on the left and right of the intermediate portion in the longitudinal direction of the article receiving portion 60. The support shaft 61 is pivotally supported on the front end side bearing portion 42A of the left and right support frame arms 42. The support frame plate 41 of the support frame 40 is provided with a lifting actuator 50 such as a pneumatic type or an electric type. A slide block 52 that slides in a linear direction along a guide rail 51 of the lifting actuator 50 is attached to a base of the article receiving portion 60. A slide base 62 provided on the end side is connected. The article receiving portion 60 is moved up and down around the support shaft 61 by driving of the lifting actuator 50, and the tip end portion of the article receiving portion 60 is at the receiving position opposite to the charging chute 101, and the tip end from the support shaft 61 of the article receiving portion 60. The side portion forms an upward inclination angle θ1 upward with respect to the horizontal plane. At the discharge position where the tip of the article receiver 60 is opposed to the discharge chute 102, the tip side portion of the article receiver 60 from the support shaft 61 forms a downward inclination angle θ2 downward with respect to the horizontal plane.

  The article receiving section 60 is composed of a plurality of long guide bars 64 supported at a plurality of positions in the circumferential direction of the frame of the frame-shaped guide bar support plate 63, and a plurality of articles are slid by the guide bars 64. Alternatively, an article receiving space 65 that can be accommodated by pressing is formed. The article receiving section 60 makes the opening of the article receiving space 65 relative to the input chute 101 and the discharge chute 102 so that the article can be received and discharged. The above-described support shaft 61 is provided on a guide bar support plate 63 provided in an intermediate portion in the longitudinal direction of the article receiving portion 60. An article stopper 66 is provided on the guide bar support plate 63 on the distal end side of the article receiving portion 60. The article stopper 66 opens and closes the opening of the article receiving space 65 by a projecting portion such as an air cylinder, and the article receiving portion 60 is turned. When the product is lowered, the product stopper 66 is closed to prevent the product stored in the product receiving space 65 from jumping out from the opening of the product receiving space 65. The length of the article receiving portion 60 needs to be long enough to accommodate a plurality of articles, and preferably needs to be able to accommodate three or more articles, more preferably 5 or more articles. If the number of stored items is small, it will be necessary to frequently swing up and down and turn 180 degrees around the horizontal axis, which reduces productivity. The productivity increases as the maximum number of storages increases, but if the number is too large, the length of the article receiving portion 60 increases, thereby increasing the size of the apparatus in the horizontal direction, swinging up and down, and 180 around the horizontal axis. As a driving device that performs turning, a high output one must be selected. The maximum value of the length of the article receiving portion 60 is appropriately determined depending on the size of the article, but is preferably about 300 mm to 2000 mm, and more preferably about 500 mm to 1250 mm.

  In the article selection / reversal device 100, if the inclination angles θ1 and θ2 of the article receiver 60 set by the lifting actuator 50 are the minimum angles at which the article itself slides within the guide bar 64 of the article receiver 60, the article receiver Since the turning radius of the tip portion of the 60 guide bars 64 is reduced, the apparatus can be made compact. If only the article receiving unit 60 is moved up and down, the magnitudes of θ1 and θ2 may be different, but when the turning operation of the article receiving unit 60 is performed, θ1 = θ2 by the turning operation itself. In order to use both the charging chute 101 and the discharging chute 102 for turning and raising / lowering and to improve the combined use of the apparatus, it is preferable to make the sizes of θ1 and θ2 substantially the same during the raising / lowering operation of the article receiving portion 60. The magnitudes of θ1 and θ2 are preferably 7 degrees to 65 degrees, and particularly preferably 10 degrees to 30 degrees. If this angle is large, the movement range of the tip of the article receiving portion 60 becomes large, and the height direction of the apparatus becomes large. In addition, if the angle is large, the movement of the article in the article receiving space 65 becomes unstable, and troubles such as clogging at the time of receiving or discharging may occur. On the other hand, if the angle is too small, the article stops at the article receiving portion 60, and it becomes impossible to store or discharge a certain number of articles by sliding or pushing the article itself.

  The guide bar 64 of the article receiving unit 60 includes a plurality of guide bars such as a round bar, a square bar, and a plate material. Here, in order to reduce θ1 and θ2 for the same purpose as described above, the guide bar 64 is designed to minimize the contact area between the guide bar 64 and the article or to improve the slipperiness of the contact portion with the article. It is preferable to reduce the static friction coefficient and the dynamic friction coefficient between the guide bar 64 and the article by sticking a tape having good surface treatment or slipperiness to the guide bar 64. The article receiving portion 60 is optimally composed of a plurality of guide bars 64 having the shape as described above, but does not have a protruding portion such as a tube, such as a regular cap 2 as shown in FIG. When handling an article, a simple round pipe or square pipe may be used.

  It is preferable to use a simple round pipe or square pipe as the guide bar 64 because the structure of the article receiving portion 60 can be simplified and manufacturing is easy. However, the contact area between the article and the article receiving portion 60 is increased, and the article is difficult to slip. In preparation for this, it is preferable to increase θ1 and θ2 in order to improve the slipperiness of the contact portion between the guide bar 64 and the article.

  When handling articles with protruding parts such as a trigger cap shown in FIG. 9, a small screw shown in FIG. 11, a pump cap shown in FIG. 12, or the like, a simple round pipe or square pipe is used instead of passing through the protruding part. You may provide the notch which makes possible a round pipe or a square pipe.

  By doing in this way, an article | item becomes easy to slide on a guide bar. As a result, the inclination of the article receiving portion 60 can be reduced, and the moving range of the tip can be narrowed compared to the case where a simple round pipe or square pipe is used, so the height required for the operation of the apparatus is reduced.

  The article selection reversing device 100 attaches and detaches the support frame plate 41 of the support frame 40 of the article receiving unit 13 to the recess of the turning base 30 of the turning means 12, as shown in FIG. The article receiving unit 13 can be exchanged for the turning means 12. If the new article is an article that is discharged after being turned upside down, it is not necessary to provide the support frame 40 with a lifting mechanism such as the lifting actuator 50.

  Hereinafter, the article processing operation by the article selection reversing device 100 will be described with respect to an article that performs upside down (trigger cap 1 and regular cap 2) and an operation that does not perform upside down (small screw 3 and pump cap 4). To do.

(A) When inverting upside down As shown in FIG. 9, when the trigger cap 1 is unloaded from the conveying member 101 such as a round bar of a center of gravity type aligner or a belt conveyor, the center of gravity G on the head is lowered. In the next process (cap tightening), when it is desired to turn it upside down, it is necessary to turn it upside down and discharge it to the discharge chute 102.

  As shown in FIG. 10, when the regular cap 2 is unloaded from the conveying member 101 such as a round bar such as a parts feeder or a belt conveyor, the article is received in a stable posture in which the center of gravity G on the side close to the top surface is downward. In the next process (cap tightening), when it is desired to turn the head upside down, it is necessary to turn it upside down at the article receiving portion 60 and discharge it to the discharge chute 102.

  The article selection reversing device 100 operates as follows for the articles of the trigger cap 1 and the regular cap 2. The articles in the article receiver 60 are not shown.

A fixed number of articles are accommodated in the article receiving unit 60 by sliding or pressing the articles themselves.

  (2) When a certain number of articles are received in the article receiver 60 in the above (1), the supply of articles from the charging chute 101 is stopped, and the turning shaft 31 of the turning base 30 is moved to the original position by the turning actuator 20 of the turning means 12. Is turned 180 degrees from the reverse position to the reverse position (FIG. 7B). The closing operation of the article stopper 66 of the article receiving unit 60 prevents the articles stored in the article receiving unit 60 from jumping out.

  (3) By turning the swivel base 30 in (2) above, the tip of the article receiving portion 60 is set to a discharge position opposite to the discharge chute 102, and the article stopper 66 of the article receiving portion 60 is opened to move the article receiving portion. The article in the unit 60 is discharged to the discharge chute 102 (FIG. 7C). If the discharge of the article stops halfway or the discharge speed is slow, use the above-mentioned methods to reduce the static friction coefficient or dynamic friction coefficient between the guide bar 64 and the article, or use auxiliary means such as pushing with air Can solve the problem. After completion of carrying out the article, the turning shaft 20 of the turning base 30 is returned to the original position by the turning actuator 20 of the turning means 12 to return to the above (1).

(B) When not turned upside down As shown in FIG. 11, when the machine screw 3 is unloaded from a conveying member 101 such as a round bar of a center of gravity type aligner or a belt conveyor, the center of gravity G in the shaft portion is In the case where the product is put into the article receiving unit 60 in a stable posture and is to be handled in this state even in the next process (screw tightening), the article receiving unit 60 needs to discharge it to the discharge chute 102 without being turned upside down.

  As shown in FIG. 12, when the pump cap 4 is unloaded from the conveying member 101 such as a round bar of a center of gravity type aligner or a belt conveyor, the article receiving portion is in a stable posture in which the center of gravity G on the shaft portion is downward. In the case where it is desired to handle in this state even in the next process (cap tightening), it is necessary to discharge to the discharge chute 102 without being turned upside down by the article receiving portion 60.

  The article selection reversing device 100 operates as follows for the articles of the machine screw 3 and the pump cap 4. The articles in the article receiver 60 are not shown.

  (1) The front end of the article receiving unit 60 of the article receiving unit 13 is set at a receiving position opposite to the loading chute 101, and the article loaded from the loading chute 101 is received by the article receiving unit 60 (FIG. 8A). . A fixed number of articles are accommodated in the article receiving unit 60 by sliding or pressing the articles themselves.

  (2) When a certain number of articles are received in the article receiver 60 in (1) above, the supply of articles from the input chute 101 is stopped, and the tip of the article receiver 60 is moved by the lift actuator 50 of the article receiver unit 13. The tip side portion of the article receiving portion 60 is inclined downward so as to be set at a discharge position opposite to the discharge chute 102 (FIG. 8B). The closing operation of the article stopper 66 of the article receiving unit 60 prevents the articles stored in the article receiving unit 60 from jumping out.

  (3) By tilting the article receiving portion 60 in the above (2), the tip end portion of the article receiving portion 60 is set to the discharge position opposite to the discharge chute 102, the article stopper 66 of the article receiving portion 60 is opened, and the article is moved. The article in the receiving part 60 is discharged to the discharge chute 102 (FIG. 8C). If the discharge of the article stops in the middle or the discharge speed is slow, use the above-mentioned methods to reduce the static friction coefficient and dynamic friction coefficient between the guide bar 64 and the article, or use auxiliary means such as pushing with air Can solve the problem. After completion of carrying out the article, the article receiving unit 60 is returned to the receiving position by the elevating actuator 50 of the article receiving unit 13 to return to the above (1).

  In addition, about the front-back asymmetrical articles like a trigger cap, the front-back direction of the said articles | goods in the front process or back process of the goods selection inversion apparatus 100 was the state which aligned in one direction from the uneven state (FIG. 13 (A)) ( It is desirable to arrange in FIG. That is, it is difficult to align the front-rear direction of an asymmetrical article such as a trigger cap. For example, a method of continuously aligning the front-rear direction as shown in JP-A-11-139543 or picking one by one intermittently Therefore, it is necessary to use a method of aligning the front-rear direction. In particular, if the front-and-rear alignment is performed in the previous process of the article selection reversing device 100, the articles are directed in the same direction in the guide bar 64 of the article receiving unit 60, and the articles are inserted into and discharged from the guide bar 64. The article movement behavior at the time is further stabilized, and troubles such as article clogging can be suppressed.

According to the present embodiment, the following operational effects can be obtained.
(a) In the article selection reversing device 100, when the article is inverted upside down, the tilting angle of the article receiving portion 60 with respect to the support frame 40 is not changed, and the turning means 12 on which the support frame 40 is mounted is 180 degrees. By turning, the article received in the article receiving part 60 can be turned upside down by 180 degrees, that is, turned upside down.

  When the article is not turned upside down, the article received in the article receiving part 60 can be discharged as it is without being turned upside down by switching the inclination angle of the article receiving part 60 with respect to the support frame 40 to the opposite side of the horizontal plane. .

  (b) When the size or form of an article is to be significantly changed, the new article receiving unit 13 corresponding to the size or form of the new article can be easily replaced with the old article receiving unit 13 by attaching it to the turning means 12.

  (c) The inclination angle of the article receiving portion 60 can be easily changed by the elevating actuator 50, and the turning means 12 can be easily turned by the turning actuator 20.

  (d) Since the article receiving portion 60 forms the article receiving space 65 with a plurality of guide bars 64, the article receiving space 65 corresponding to articles of various sizes and forms can be easily formed, and a large number of articles can be formed. A long article receiving space 65 can be received and processed at a time.

(Example 2)
The article selection reversing device 200 of the second embodiment shown in FIGS. 14 to 18 is different from the article selection reversing device 100 of the first embodiment described above in that a set (substantially the article selection) composed of the turning means 12 and the article receiving unit 13. Two sets (first selective reversing unit 100A and second selective reversing unit 100B) of the reversing device 100) are provided on the base plate 11, and the article receiving portion 60A of the article receiving unit 13 of each selective reversing unit 100A, 100B. , 60B can be positioned alternately on each of the single input chute 101 and the first and second two discharge chutes 102A, 102B.

First discharge chute Positioned to 02A.

  As the linear motion actuator 203, a pneumatic type, an electric type, or the like is selected. Since the moving time of the first and second article receiving portions 60A and 60B by the actuator 203 is a dead time, a high-output servo motor or stepping motor that enables high speed and high acceleration / deceleration is particularly preferable. In actual operation, the discharge position may vary slightly depending on the machining and assembly accuracy of the parts and the stop position of the swing and swivel, depending on the choice of swing and swivel. It is also preferable to use a stepping motor from the point that arbitrary fine adjustment of the stop position is possible.

  Hereinafter, the article processing operation by the article selection reversing device 200 will be described with respect to an article that performs upside down (trigger cap 1, regular cap 2) and an action that does not perform upside down (small screw 3, pump cap 4). To do.

(A) When flipping up and down The article selection inversion device 200 operates as follows for the articles of the trigger cap 1 and the regular cap 2. The articles in the article receivers 60A and 60B in the first and second selective inversion units 100A and 100B are not shown.

  At this time, in the second selective reversing unit 100B, the discharge of the articles from the article receiving portion 60B to the second discharge chute 102B has been completed, and the front end portion of the article receiving portion 60B is set to the receiving position facing the charging chute 101. As described above, the base plate 11 is moved by the linear motion actuator 203 while the tip side portion of the article receiving portion 60B is inclined upward by the elevating actuator 50 of the article receiving unit 13, and the tip portion of the article receiving portion 60B is placed on the input chute 101. Move towards the opposite receiving position.

  (3) When the tip of the article receiving portion 60A of the first selective reversing unit 100A is set at the discharge position relative to the first discharge chute 102A according to the above (2), the article stopper 66 of the article receiving portion 60A is opened. It operates and discharges the articles in the article receiving portion 60A to the first discharge chute 102A (FIG. 24).

  At this time, in the second selective reversing unit 100B, the tip end of the article receiving portion 60B is set at a receiving position opposite to the throwing chute 101, and the article thrown from the throwing chute 101 is received in the article receiving portion 60B (first selection). (There is no need to wait for article discharge from the article receiver 60A of the reversing unit 100A) (FIG. 24).

  After completion of the discharge of the first selective reversing unit 100A and the acceptance of the second selective reversing unit 100B, the lifting actuator 50 of the article receiving unit 13 and the linear motion actuator 203 of the first and second selective reversing units 100A and 100B By driving, the tip of the article receiving portion 60A of the first selective reversing unit 100A is positioned at a receiving position (original position) opposite to the charging chute 101, and the article is received again in the article receiving portion 60A, and the second selective reversing unit 100B. Returning to (1) above, the tip of the article receiving portion 60B is positioned at the discharge position (reversal position) opposite to the second discharge chute 102B, and the article is discharged again from the article receiving portion 60B.

  The article selection reversing device 200 can improve the article processing efficiency with respect to the article selection reversing device 100. In other words, the article selection reversing device 100 cannot accept an article into the article receiving unit 60 (dead time) while the article receiving unit 60 is moving up and down or turning, and the article receiving unit 60 is discharging the article. The raising / lowering / turning time of the article receiving unit 60 can be shortened by increasing the output of the driving device, but the article discharging time from the article receiving unit 60 cannot be made zero. On the other hand, in the article selective reversing device 200, in the first and second selective reversing units 100A and 100B, the article receiving portion 60A and the article receiving portion 60B are moved up and down, swiveled, and the base plate 11 is moved linearly. I cannot accept it. The lifting / turning time of the article receiving portions 60A and 60B and the linear movement time of the base plate 11 can be shortened by increasing the output of the driving device. The article discharge time from the article receivers 60A and 60B in one of the first and second selective inversion units 100A and 100B is not wasted because the other article receivers 60A and 60B are receiving articles.

  Although the article selection reversing apparatus 200 has been described as having two selective reversing units 100A and 100B, there may be three or more selective reversing units similar to the article selection reversing apparatus 100. For example, this is effective when there is unevenness in the input speed of each selective inversion unit and another selective inversion unit functions as a buffer, or when there are three or more article discharge directions. Further, when two selective reversing units are used, even if the article discharge direction is three or more directions, if the linear motion rail is extended, it is possible to discharge from each selective reversing unit at an arbitrary position.

  According to the present embodiment, the article receiving portions 60A and 60B of each of the selective reversing units 100A and 100B forming a plurality of sets are alternately positioned on the single input chute 101 and the plurality of discharge chutes 102A and 102B, respectively. When the article receiving unit 60A of the selective inversion unit 100A is discharging the article, the article receiving unit 60B of the other selective inversion unit 100B can be in the process of receiving an article, and the processing capacity can be increased.
