Description

  The present invention relates to an apparatus for transferring an object to be transferred, and more particularly to an apparatus for scooping up an object to be transferred by inserting a thin plate below the object to be transferred installed at a predetermined location.

  An example of this type of device is described in Patent Document 1. The transfer device described in Patent Literature 1 is configured to insert a support plate material and scoop it up below a transfer object installed on a predetermined transfer surface. A transfer belt is wound around the support plate so as to be folded back at the front end portion on the transfer object side and the rear end portion on the opposite side. Then, as the support plate material is inserted below the transfer object, the transfer belt is fed upward from the lower side of the support plate material via the tip portion by the length corresponding to the insertion length. It is configured as follows. Therefore, according to the transfer apparatus described in this patent document 1, when a transfer belt is inserted below the transfer object, there is no relative speed difference between them. That is, since it is difficult for friction to occur between the transfer object and the transfer belt, scooping can be performed without damaging the transfer object.

Japanese Patent No. 4406775

  In the configuration described in Patent Document 1, when the transfer belt is fed to the lower side of the transfer object, a relative speed difference is generated between the transfer belt and the transfer surface. Therefore, there is a disadvantage that the transfer belt is worn by rubbing against the transfer surface, and the durability thereof is lowered. Moreover, since the replacement frequency of the film constituting the transfer belt increases, there is a lack of practicality.

  This invention was made paying attention to said technical subject, and it aims at providing the scooping apparatus which can reduce the abrasion of the film which comprises the transfer belt.

  In order to achieve the above-described object, the invention of claim 1 is a scooping device for inserting a thin plate under a transfer object placed at a predetermined location, and is stacked with a slight gap. Each thin plate is configured to move integrally with a pinion gear that moves back and forth linearly in a direction approaching and moving away from the object to be transferred by rolling while meshing with a rack. The film material is wrapped in a state of wrapping the tip portion inserted below the transfer object, and the upper film material wound on the upper upper thin plate of the two thin plates, When the upper thin plate is inserted below the transfer object, the length is the same as the insertion length, and the upper thin plate is sent from the lower side through the tip to the upper side, and the two sheets The lower part of the sheet is wrapped around the lower sheet The film material is sent to the lower side through the tip portion from the upper side of the lower thin plate as the insertion length of the lower thin plate is inserted under the transfer object. It is comprised by these.

  According to a second aspect of the present invention, in the first aspect of the invention, when the two thin plates are advanced in a direction to be inserted below the transfer object, the upper film material is used as the upper thin plate. The lower film material is moved from the lower side through the tip portion to the upper side of the upper thin plate, and the lower film material is moved from the upper side of the lower thin plate to the lower side of the lower thin plate. And when the two thin plates are retracted in the direction of being pulled out from the lower side of the transfer object, the upper film material is passed through the tip from the upper side of the upper thin plate. A film feed mechanism that travels so as to move to the lower side of the upper thin plate, and travels so that the lower film material is moved from the lower side of the lower thin plate through the tip portion to the upper side of the lower thin plate, By the pinion gear It is scooped up device and said held.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the upper film material and the lower film material are formed in an annular shape, and the film feed mechanism has a radius equal to a pitch circle radius of the pinion gear and together with the pinion gear. A scooping device comprising a rotating feed roller, wherein the upper film material is wound around the feed roller, and the lower film material is connected to the upper film material between the two thin plates. It is.

  According to a fourth aspect of the present invention, in the third aspect of the invention, the film feeding mechanism is configured such that the lower film material is wound and the lower film material is sandwiched between the feeding roller and rotates together with the feeding roller. A scooping device having a clamp roller.

  According to a fifth aspect of the present invention, in the invention according to any one of the first to fourth aspects, the distal end portion of the upper thin plate is disposed closer to the transfer object in the insertion direction than the distal end portion of the lower thin plate. A scooping device which is bent toward the lower thin plate.

  The invention of claim 6 is the invention according to any one of claims 1 to 5, further comprising a pressing plate disposed above the transfer object, wherein the pressing plate and the upper part of the transfer object are in contact with each other. The scooping device is configured to insert and remove the two thin plates to the lower side of the object to be transferred.

  According to this invention, since each thin plate approaches and separates from the transfer object together with the pinion gear, the amount of movement of each thin plate can be changed by controlling the rotation of the pinion gear. Moreover, when inserting each thin plate into the lower side of the transfer object, the upper film material is sent from the lower side to the upper side through the tip portion by the length corresponding to the insertion length of each thin plate. The lower film material is sent from the upper side to the lower side through the tip portion by the length corresponding to the insertion length of each thin plate. On the other hand, when each thin plate is pulled out from the lower side of the transfer object, the film materials are fed in the order opposite to the insertion operation described above. Therefore, in any case described above, there is no relative speed difference between the transfer object and the upper film material and between the predetermined location and the lower film material. As a result, it is possible to prevent or suppress the transfer object from being pushed or dragged by each thin plate. As a result, the transfer object can be scooped up and transferred to another predetermined position without breaking the posture of the transfer object from the predetermined position. In this case, it is possible to prevent or suppress the lower film material from being rubbed and worn at a predetermined location. Therefore, each film material can be used as long as possible, the exchange frequency thereof can be reduced, and the maintainability of the entire apparatus can be improved.

  Further, according to the present invention, the upper film material is wound around the feed roller that rotates with the pinion gear with the same outer diameter as the pinion gear, so that the amount of movement of the pinion gear is equal to the length of the upper film material fed from the feed roller. it can. And since the lower film material is connected with the upper film material, a lower film material can be sent and pulled out to the lower side of a transfer target object synchronizing with an upper film material. The lower film material is wound around a clamp roller that rotates together with the feed roller, and is sandwiched between the rollers. Therefore, when the clamp roller rotates, the lower film material is sent out from the clamp roller to the lower thin plate by the rotation, and the lower film material can be prevented or suppressed from sliding with respect to the clamp roller. As a result, the tension of the upper film material and the lower film material can be prevented or suppressed.

  Furthermore, according to this invention, the front-end | tip part of an upper thin plate is arrange | positioned rather than the front-end | tip part of a lower thin plate, and is bent to the lower thin plate side. When each thin plate is inserted below the transfer object, first, the tip of the upper thin plate is inserted below the transfer object, and then the lower thin plate is inserted. That is, since the thin plates are inserted one by one under the transfer object, the insertion operation can be performed smoothly. In this case, the transfer object is pressed at a predetermined location by a pressing plate. Therefore, each thin plate can be inserted and removed from the lower side of the transfer object while maintaining the posture of the transfer object.

  Next, the present invention will be described more specifically. FIG. 1 is a view showing an example of a scooping device according to the present invention, in which (a) is a side view of the scooping device according to the present invention, and (b) is an I-I shown in (a) of FIG. It is sectional drawing of the scooping apparatus which concerns on this invention along a line, (c) is a figure which shows the state in which the film is wound around each thin plate. The upper thin plate 1 is formed in a rectangular shape as an example. On the lower side of the upper thin plate 1, a lower thin plate 2 that is similarly formed in a rectangular shape is disposed. The lower thin plate 2 is integrally provided on a fixing portion 3 such as a case or a frame. The thin plates 1 and 2 are integrated with a small gap by a fixing member such as a bolt or a nut (not shown). In the thin plates 1 and 2 integrated in this way, one end portion 1a of the upper thin plate 1 is slightly shifted from the one end portion 2a of the lower thin plate 2 as shown in FIGS. It arrange | positions at the mounting target object w side. Further, an arm ra such as a suspension device or a robot arm is attached to the fixed portion 3 on the side opposite to the thin plates 1 and 2, and is configured to be transportable to a predetermined location.

  A motor case 5 of the servo motor 4 is fixed to the fixing portion 3. A pinion gear 7 that is an external gear is concentrically connected to the rotor shaft 6 of the servo motor 4. A rack 8 formed with teeth that mesh with the pinion gear 7 is provided on the inner wall surface of the fixed portion 3 opposite to the thin plates 1 and 2. In the following description, when the servo motor 4 is rotated forward, the pinion gear 7 rolls on the rack 8 so as to approach the transfer object w arranged on the left side in FIG. It will be described as moving. Further, it is assumed that when the servo motor 4 is rotated in the reverse direction, the pinion gear 7 rolls on the right side in FIG. 1A, that is, on the rack 8 so as to be separated from the transfer object w. Furthermore, a control device (not shown) is provided, and the rotation of the servo motor 4 is controlled by the control device.

  Feed rollers 9 that rotate together with the pinion gear 7 are provided on both sides of the pinion gear 7. The feed roller 9 is arranged concentrically with the rotor shaft 6 and the pinion gear 7, and the radius thereof and the pitch circle radius of the pinion gear 7 are set to be substantially the same. A film is wound around the feed roller 9 and the thin plates 1 and 2 as will be described later. When the pinion gear 7 is rotated by the servo motor 4, the feed roller 9 rotates with the rotation. The film is sent out from the feed roller 9. Further, the thin plates 1 and 2 are integrated with the pinion gear 7 so as to move back and forth with respect to the transfer object w.

  As shown in FIG. 1C, the one end portion 10a of the film 10 described above is folded at the one end portion 1a from the upper side to the lower side of the upper thin plate 1, and then disposed on the opposite side to the one end portion 1a. The lower thin plate 2 is wound around the other end 2b. Further, the one end portion 10 a wraps around the other end portion 2 b and the lower thin plate 2 and is folded back at one end portion 2 a of the lower thin plate 2 so as to be disposed on the upper side of the lower thin plate 2. The other end portion 10 b of the film 10 wraps around the upper side and the other end portion 1 b of the upper thin plate 1, is folded back at the other end portion 1 b, and is disposed below the upper thin plate 1. The end portions 10a and 10b of the film 10 are connected between the thin plates 1 and 2 by a tape 11 or an adhesive. That is, the film 10 is wound around the thin plates 1 and 2 as shown by the numeral “8” as shown in FIG. Therefore, the thin film 1 and 2 are in a state where the film 10 is wound around in an annular shape. The film 10 is made of, for example, polyethylene terephthalate resin (PET).

  In the following description, an annular portion of the film 10 that is wound around the upper thin plate 1 is referred to as an upper film 10c, and an annular portion that is wound around the lower thin plate 2 is referred to as a lower film 10d. Moreover, it demonstrates as what the one end parts 1a and 2a of each said thin plate 1 and 2 are arrange | positioned at the transfer target object w side, and these one end parts 1a and 2a are called the front-end | tip parts 1a and 2a. Furthermore, the above-mentioned adhesion site is indicated by the symbol “a” in FIG.

  As shown in FIG. 1C, the upper film 10 c is wound around the feed roller 9, and the lower film 10 d is wound around the clamp roller 12. The clamp roller 12 is pressed against the feed roller 9 through the film 10. That is, the film 10 is sandwiched between the rollers 9 and 12. The clamp roller 12 rotates in the direction opposite to the rotation direction of the feed roller 9. Therefore, for example, when the thin plates 1 and 2 are brought close to the transfer object w, the upper film 10 c is sent out from the feed roller 9 without sliding from the lower side to the upper side of the upper thin plate 1. Further, the lower film 10 d is fed out from the clamp roller 12 without sliding from the upper side to the lower side of the lower thin plate 2. Thus, by feeding out the films 10c and 10d by the rotation of the rollers 9 and 12, it is possible to prevent either of the films from being pulled by one of the films and the tension of those films from becoming excessive. Suppressed. A plurality of tension rollers 13 are provided. Each tension roller 13 is configured to be in a predetermined range by contacting the films 10c and 10d to prevent or suppress the slack of the films. The feed roller 9 and the clamp roller 12 described above correspond to the film feed mechanism in the present invention.

  Further, the scooping device according to the present invention includes a pressing device 14 as shown in FIG. The pressing device 14 has a pressing plate 15 that contacts the upper part of the transfer object w. The pressing plate 15 is configured to press the transfer target object w by contacting the upper part of the transfer target object w placed on the table or placed on the upper thin plate 1. Moreover, it is comprised so that the attitude | position of the transfer target object w may be maintained by pressing down. For example, when scooping up the transfer object w arranged on the table, each thin plate 1 is placed below the transfer object w in a state where the upper part of the transfer object w and the holding plate 15 are in contact with each other. 2 is inserted and removed. In this case, since the transfer object w is sandwiched between the pressing plate 15 and the table ta, the inclination of the transfer object w due to the insertion operation of the thin plates 1 and 2 is prevented or suppressed. In this way, the posture of the transfer object w is maintained. In the example shown here, the pressing plate 15 is attached to one end of a rod 16 and is slidably attached to the cylinder 17 via the rod 16. A stopper 18 is attached to the other end of the rod 16. That is, the holding plate 15 moves away from the cylinder 17 by moving downward in FIG. 1A due to its own weight, and approaches the cylinder 17 by moving upward in FIG. 1A due to external force. Is configured to do. A screw hole 19 is formed in the cylinder 17, and the cylinder 17 is fixed to a fixed frame 21 integrated with the fixing portion 3 by a screw 20 that meshes with the screw hole 19. The pressing plate 15 described above may be configured to move up and down by a conventionally known electric cylinder or air cylinder.

  FIG. 2 is an enlarged view of the tip portions 1a and 2a of the thin plates 1 and 2 integrated as described above. The leading end 1a of the upper thin plate 1 is disposed so as to protrude toward the transfer object w by a predetermined length from the leading end 2a of the lower thin plate 2. Further, the protruding tip end portion 1a is bent toward the lower thin plate 2 by a predetermined angle with respect to the other portion 1c. In the example shown in FIG. 2, the distance d1 between the tip portion 1a and the tip portion 2a is set to 10 mm. The bending angle θ1 of the tip 1a is set to 7 °. This is because the thickness of the tip of each of the thin plates 1 and 2 integrated as described above is reduced so that the insertion operation can be performed smoothly. By configuring each of the thin plates 1 and 2 as described above, it is possible to make the thickness of the tip portion substantially equal to that of one thin plate. In the example shown in FIG. 2, the angle between the table ta and the lower thin plate 2, that is, the insertion angle θ2 of the thin plates 1 and 2 is set to 5 °. The insertion angle θ2 may be around 5 °, but is more preferably set to 5 ° or less. This is to suppress the lowering of the durability of the upper film 10c due to the upper film 10c being rubbed against the table ta by suppressing the contact between the tip 1a and the table ta. In addition, in a state where the insertion angle θ2 is set to 5 ° or less, it is preferable to set the angle obtained by adding the bending angle θ1 and the insertion angle θ2 to 12 ° or less. For example, when the bending angle θ1 is set to 8 °, the insertion angle θ2 is preferably set to 4 °. When the insertion angle θ2 is larger than 5 ° or the total angle is larger than 12 °, each of the transfer objects w is inserted when the thin plates 1 and 2 are inserted below the transfer object w. There is a possibility that the upper side surface of the upper thin plate 1 is pressed against the side surfaces of the thin plates 1 and 2. That is, it becomes difficult to insert the thin plates 1 and 2 below the transfer object w. Further, the tip portion 1a and the table ta may come into contact with each other and the table ta and the upper film 10c may be rubbed. Furthermore, when the transfer target object w is placed on the upper thin plate 1, the inclination of the transfer target object w becomes large, and the posture of the transfer target object w may collapse.

  In the example shown in FIGS. 1 and 2, the upper thin plate 1 is formed of a stainless steel plate or a synthetic resin plate having a thickness t1 of 1.5 mm. The lower thin plate 2 is formed of a stainless steel plate or a synthetic resin plate having a thickness t2 of 1.5 mm. The total thickness t3 of the thin plates 1 and 2 integrated by bolts and nuts is set to 3.5 mm, and the distance d2 between the thin plates 1 and 2 is set to 0.5 mm.

  FIG. 3 is a diagram for explaining the operation of inserting the thin plates 1 and 2 below the transfer object w. FIG. 3A shows the thin plates 1 and 2 below the transfer object w. It is a figure which shows the state inserted, (b) is a figure which shows the state which extracted each thin plate 1 and 2 from the lower side of the transfer target object w. For example, when the servo motor 4 is rotated forward, the pinion gear 7 and the feed roller 9 move to the transfer object w side while rotating. The thin plates 1 and 2 approach the transfer object w along with the movement. In that case, it is preferable to move the thin plates 1 and 2 while keeping them parallel to the transfer object w installed at a predetermined location such as the table ta or the work table.

  Next, the thin plates 1 and 2 are simultaneously advanced toward the table ta and the transfer object w. And each front-end | tip part 1a, 2a is slightly inserted under the transfer target object w. In that case, it is preferable that the insertion angle is set to 5 ° or less, and the distal end portion 1a and the upper film 10c are not brought into contact with the table ta. Further, in the scooping device according to the present invention, the distal end portion 1a of the upper thin plate 1 is disposed so as to protrude from the distal end portion 2a of the lower thin plate 2 toward the transfer object w. 1a is inserted below the transfer object w. Next, the tip 2 a of the lower thin plate 2 is inserted between the table ta and the upper thin plate 1. The lower thin plate 2 is inserted between the upper thin plate 1 and the table ta. As a result, even when the gap between the table ta and the transfer object w is small, the insertion operation of the thin plates 1 and 2 can be performed smoothly. In addition, the insertion speed and drawing speed of each thin plate 1 and 2 are set to 0.1 to 0.25 m / s.

  Further, since the feed roller 9 and the pinion gear 7 rotate integrally as described above, the upper film 10c moves upward from the lower side of the upper thin plate 1 via the tip 1a as the feed roller 9 rotates. Sent. In that case, since the pitch circle radius of the pinion gear 7 and the radius of the feed roller 9 are set to be substantially the same, the feed amount of the upper film 10c is a length corresponding to the insertion length of the thin plates 1 and 2. ing. Therefore, there is no relative speed difference between the transfer object w and the upper film 10c. Further, the lower film 10d is fed out from the clamp roller 12 in synchronization with the feeding operation of the upper film 10c. The lower film 10d is sent from the upper side of the lower thin plate 2 to the lower side via the tip portion 2a. The feed amount of the lower film 10d is a length corresponding to the insertion length of the thin plates 1 and 2. Therefore, there is no relative speed difference between the table ta and the lower film 10d. As a result, the upper film 10c apparently does not move with respect to the transfer object w, and the lower film 10d does not move with respect to the table ta. On the other hand, the connection part a moves between the thin plates 1 and 2 toward the transfer object w.

  Then, the rotation of the servo motor 4 is stopped in a state where the films 10c and 10d are fed over almost the entire lower surface of the transfer object w. In this state, the transfer object w is transferred onto the upper thin plate 1 via the upper film 10c. FIG. 3A shows this state. Thereafter, when the whole fixed portion 3 is lifted, the transfer object w is scooped up from the table ta.

  Next, a case where the scooped transfer object w is installed at another predetermined location will be described. FIG. 3B shows an example in which the transfer object w1 that has been scooped up as described above is placed on the transfer object w2 having the same outer shape. When the transfer target object w1 is arranged on the upper thin plate 1, the transfer target object w1 is moved onto the transfer target object w2 while keeping the thin plates 1 and 2 horizontal. Then, by lowering the scooping device, the transfer object w1 is superposed on the transfer object w2 so that their outer shapes are aligned. Thereafter, the servo motor 4 is rotated in the reverse direction, and the pinion gear 7 and the feed roller 9 are translated in the right direction in FIG. That is, the thin plates 1 and 2 are pulled out from between the transfer objects w1 and w2. In that case, each film 10c, 10d is sent out in the reverse order to the insertion operation described above. That is, the upper film 10 c is fed from the upper side to the lower side via the tip portion 1 a of the upper thin plate 1 and the lower film 10 d is moved to the tip of the lower thin plate 2 by a length corresponding to the amount of movement of the pinion gear 7 and the feed roller 9. It is sent from the lower side to the upper side via the part 2a. Therefore, when the thin plates 1 and 2 are pulled out, the transfer objects w1 and w2 can be prevented or suppressed from being dragged and moved by the thin plates 1 and 2. And said connection site | part a moves to the right direction in (b) of FIG.

Embodiment FIG. 4 is a diagram showing an example of the operation of the scooping device according to the present invention. First, as shown in FIG. 4 (a), the scooping device is moved by the robot arm ra, and the pressing plate 15 is arranged above the transfer object w1. In this state, the pressing plate 15 moves downward due to its own weight and is farthest from the cylinder 17. Next, the scooping device is moved downward in FIG. As the scooping device descends, the pressing plate 15 comes into contact with the upper portion of the transfer object w1, and the lowering of the pressing plate 15 stops. As the scooping device further descends, the rod 16 slides inside the cylinder 17 accordingly. As a result, the holding plate 15 approaches the cylinder 17. Then, when the lower thin plate 2 comes into contact with the table ta, the descent of the scooping device is stopped. In this state, the distance between the pressing plate 15 and the thin plates 1 and 2 is a length corresponding to the thickness of the transfer object w1. In addition, the transfer object w1 is pressed against the table ta by a load corresponding to the weight of the pressing plate 15. Therefore, the inclination of the transfer object w is prevented or suppressed by the pressing plate 15.

  Next, as shown in FIG. 4C, the thin plates 1 and 2 are inserted below the transfer object w. The feeding operation of the films 10c and 10d accompanying the insertion operation of the thin plates 1 and 2 is as described with reference to FIG. As a result, the transfer object w is placed between the pressing plate 15 and the upper thin plate 1 or is sandwiched between them. In this state, the posture of the transfer object w is maintained by the pressing plate 15 and the thin plates 1 and 2. Next, as shown in FIG. 4D, the scooping device is moved to align the outer shape of the transfer object w1 with the outer shape of the other transfer object w2. In that case, it is preferable to keep the thin plates 1 and 2 parallel. Thereafter, the scooping device is moved downward in FIG. 4E, and the lowering is stopped when the lower thin plate 2 comes into contact with another transfer object w2. Next, as shown in FIG. 4F, the thin plates 1 and 2 are pulled out from between the transfer objects w1 and w2. The pulling operation is as described in FIG. When the drawing operation is completed, the transfer object w1 is directly stacked on the transfer object w2, and the transfer operation is completed. In the state shown in FIG. 4F, the transfer objects w1 and w2 are still pressed against the table ta by a load corresponding to the weight of the pressing plate 15. Thereafter, the scooping device is moved as shown in FIG. The stacked transfer objects w1 and w2 are supplied to the next process such as bagging and inspection (not shown).

  Therefore, according to the scooping device according to the present invention, when scooping up the transfer target object w installed at a predetermined location, the relative speed difference between the predetermined location and the transfer target object w does not occur. The thin plates 1 and 2 can be inserted between them. In particular, it is possible to prevent or suppress the lower film 10d from being worn by rubbing against a predetermined portion. That is, it is possible to suppress a decrease in durability of the films 10c and 10d. Thereby, each film 10c, 10d can be used as long as possible. Moreover, the replacement frequency of each film 10c, 10d can be reduced, the member cost as the whole apparatus can be reduced, and maintainability can be improved. Further, since the transfer object w can be prevented or suppressed from being pushed or dragged by the thin plates 1 and 2, the transfer operation of the transfer object w can be performed smoothly.

In order to achieve the above-described object, the invention of claim 1 is a scooping device for inserting a thin plate under a transfer object placed at a predetermined location, and is stacked with a slight gap. Each thin plate is configured to move integrally with a pinion gear that moves back and forth linearly in a direction approaching and moving away from the object to be transferred by rolling while meshing with a rack. The film material is wrapped in a state of wrapping the tip portion inserted below the transfer object, and the upper film material wound on the upper upper thin plate of the two thin plates, When the upper thin plate is inserted below the transfer object, the length is the same as the insertion length, and the upper thin plate is sent from the lower side through the tip to the upper side, and the two sheets The lower part of the sheet is wrapped around the lower sheet The film material is sent to the lower side through the tip portion from the upper side of the lower thin plate as the insertion length of the lower thin plate is inserted under the transfer object.
