Description

The present invention relates to a support device used when transporting a product or the like being manufactured in a factory and a transport device including the support device.

When manufacturing products in a factory, products in the process of being manufactured, finished products, or manufacturing equipment may be transported. As an example, an apparatus used for transporting a mold is known (see, for example, Patent Document 1). Patent Document 1 discloses a configuration in which a mold placed on a stand is prevented from falling from the stand and the mold can be conveyed from the stand when necessary. Specifically, the stand is provided with a stop means. The stop means has an operating tool. The operating tool is arranged so as to be pushed by the stop release means. When the operating tool is pushed by the stop release means, the operating tool changes the contact state with the stopper tool in contact with the operating tool. As a result, the stopper swings around the pin. By swinging the stopper tool, the connection between the stopper tool and the mold is released. As a result, the stopper for preventing the mold from falling is prevented from interfering with the transportation of the mold.

Japanese Unexamined Patent Publication No. 6-99231

By the way, in the manufacture of an endless annular transmission belt, constituent members such as a rubber sheet, a reinforcing cloth, and a core cord are wound in order around a cylindrical mold in a molding process. Next, a belt sleeve is produced by performing vulcanization in the vulcanization step. Then, after removing the belt sleeve from the mold, the transmission belt is obtained by cutting the belt sleeve to a predetermined width.

The outer diameter of the cylindrical portion of the mold that receives the belt sleeve differs depending on the circumference of the transmission belt (belt sleeve) (for example, the outer circumference length is 152 to 711 mm). Further, the outer diameter of the shafts provided at both ends of the mold may be different between the small-diameter mold and the large-diameter mold (for example, the end shaft diameter of the small-diameter mold is φ45 and the large diameter is large. The end shaft diameter of the mold is φ70).

In recent years, the transfer of molds between the above-mentioned manufacturing processes has been automated. For example, the mold around which the belt sleeve is wound can be placed on the stand in an upright state by inserting the end shaft portion at the lower end into a hole or the like of the stand in a state where the belt sleeve is erected vertically. Since the mold is supported by the stand, it is conveyed by a conveyor or the like without falling.

However, there are many problems in transporting these molds when molds having different outer diameters of the lower end shafts coexist as described above. Here, the following configurations (1) to (3) can be considered as a configuration suitable for transporting each of the molds having different outer diameters of the end shaft portions.

As the configuration (1), a stand for a small diameter shaft having a hole sized to match the end shaft portion of the small diameter mold and a hole portion sized to match the end shaft portion of the large diameter mold are provided. It is possible to consider a configuration in which a stand for a large-diameter shaft to be provided is prepared. In this case, a sensor that detects the shaft diameter of the mold, an actuator for selectively arranging two large and small pedestals at a position (mounting position) on which the mold is mounted, and a transfer of each pedestal are controlled. A control device is further provided. With such a configuration, the control device controls each pedestal so that the pedestal suitable for the shaft diameter detected by the sensor is conveyed to the mounting position.

Further, as (2), it is possible to consider a configuration in which a stand having a plurality of movable claws (movable arms) operated by an actuator is prepared. In this case, the mold is held on the stand by the plurality of movable claws working together to grasp the shaft of the mold.

Further, as (3), a configuration in which a tubular attachment is attached to the end shaft portion of a mold having a small diameter end shaft portion can be considered. The outer diameter of the tubular attachment is set to be the same as the outer diameter of the large-diameter end shaft portion. With this configuration, a mold having a small diameter end shaft can be installed with high positional accuracy on a stand in which a hole having a hole diameter suitable for a large diameter end shaft is formed.

However, in the case of the above configuration (1), a large number of members such as a sensor, an actuator, and a control device are required, resulting in a complicated configuration. Further, if the sensor erroneously detects the shaft diameter, a stand unsuitable for the mold will be placed at the mounting position. For example, when a small diameter end shaft is inserted into a hole in a pedestal for a large diameter end shaft, the small diameter end shaft is not supported by the inner peripheral surface of the pedestal hole, resulting in gold. The mold may fall on the table. Further, for example, when the large-diameter end shaft portion is to be inserted into the hole portion of the stand for the small-diameter end shaft portion, the large-diameter end shaft portion cannot enter the hole portion of the stand. , There is a risk that the mold cannot be transported by the stand.

Further, in the case of the above configuration (2), an actuator for operating the movable claw is required. Further, when a configuration is provided in which the mold is automatically controlled by using a hoist for carrying out the mold from the stand, a plurality of movable claws chucking the end shaft portion are provided on the end shaft portion. It is necessary to match the timing of releasing the chuck and the timing of hanging the mold with the hoist for carrying out the mold from the stand. Therefore, the configuration of mold transfer becomes complicated.

Further, in the case of the above configuration (3), when many types of molds having different diameters of the end shaft portions are used, it is definitely difficult to accurately attach the attachments corresponding to the respective types of molds. Further, it takes a lot of man-hours to attach / detach the attachment to / from the end shaft portion.

In view of the above background, the present invention can support the transfer of support objects (molds, etc.) of different sizes without using complicated configurations such as sensors and actuators, and can support the support objects with simpler work. It is an object of the present invention to provide a support device which can be attached and detached, and a transport device provided with the support device.

(1) In order to solve the above problems, the support device according to a certain aspect of the present invention includes a casing forming an insertion space into which a predetermined support object is inserted, and a holding portion for holding the support object in the insertion space. , And a pressing member including an urging portion that generates an urging force that urges the pressing portion toward the inside of the insertion space, and the pressing member inserts the support object into the insertion space. The supporting object is supported by the casing so as to allow the pressing portion to be displaced toward the outside of the insertion space against the urging force as the pressing portion pressurizes the pressing portion.

According to the above configuration, as the supporting object pressurizes the pressing portion by inserting the supporting object into the insertion space, the pressing portion may be displaced to the outside of the insertion space against the urging force of the urging portion. It is possible. As a result, for example, when the large-diameter shaft portion to be supported having the large-diameter shaft portion is inserted into the casing, the pressing portion is pushed toward the outside of the insertion space by the large-diameter shaft portion, so that the large-diameter shaft portion has a large diameter. Displace to a position suitable for holding the shaft. On the other hand, for example, when the small-diameter shaft portion to be supported having the small-diameter shaft portion is inserted into the casing, the pressing portion is not displaced and remains in a position suitable for pressing the small-diameter shaft portion. You can also hold down the part. With such a configuration, regardless of the size of the support object inserted into the insertion space, the support object can be supported in a stable posture by appropriately pressing the support object with the pressing portion. That is, it can correspond to each transport of support objects of different sizes. In addition, the support device can support the transfer of support objects of different sizes without using complicated configurations such as sensors and actuators. Further, the pressing member is displaced by the force applied from the supporting object to the pressing portion as the supporting object is inserted into the insertion space, so that the pressing portion moves to an appropriate position. Therefore, it is not necessary to attach a special member such as an attachment to fill the gap between the support target and the receiving portion. As a result, the support target can be attached to and detached from the support device with a simpler operation. Based on the above, according to the present invention, it is possible to carry each of the support objects (molds, etc.) of different sizes without using a complicated configuration such as a sensor or an actuator, and the support object can be supported by a simpler operation. It is possible to realize a support device that can be attached and detached.

(2) The pressing member may be rotatably supported by the casing around a predetermined support shaft.

According to this configuration, the pressing portion can be arranged at a position suitable for pressing the support target by a simple and compact configuration in which the pressing member rotates around the support shaft.

(3) The urging portion may include a weight portion provided on the pressing member.

According to this configuration, the weight portion can act on the receiving portion by the moment around the support shaft. By providing the weight portion in this way, it is possible to apply an urging force to the receiving portion without using a complicated configuration such as an actuator.

(4) The holding portion may include an arc-shaped portion having the central axis of the support shaft as the central axis.

According to this configuration, when the support object collides with the receiving portion when the supporting object is inserted into the insertion space, the normal force acting on the receiving portion is a force in the direction passing through the central axis of the support shaft. That is, the direction of the collision vector acting on the holding member from the support target is the direction passing through the central axis of the support axis. As a result, the pressing member is prevented from generating an unnecessary rotational motion due to the collision with the supporting object.

(5) The casing includes a stopper portion for regulating the displacement of the pressing member around the support shaft, and when the pressing portion advances by a predetermined amount inside the insertion space, the pressing member moves the stopper. It may be configured to be received by the department.

According to this configuration, the stopper portion can regulate the displacement of the pressing portion more than necessary.

(6) The pressing portion is configured to be capable of selectively pressing a predetermined small-diameter shaft portion related to the support target and a large-diameter shaft portion thicker than the small-diameter shaft portion, and the pressing portion is configured. When receiving the small diameter shaft portion, the pressing member may be configured to be received by the stopper portion.

According to this configuration, when the pressing portion receives the small-diameter shaft portion, the pressing member does not have to rotate around the support shaft, or the amount of rotation of the pressing member can be reduced. With such a configuration, the work of inserting the small diameter shaft portion into the insertion space can be simplified.

(7) The insertion space is open upward in the vertical direction, and the support shaft may be arranged in the horizontal direction.

According to this configuration, when the support object is inserted into the insertion space along the vertical direction, the holding member can rotate around the support shaft more smoothly due to gravity.

(8) A plurality of the holding members may be provided so as to cooperate with each other to sandwich the supporting object.

According to this configuration, the support target can be supported in a more stable posture by the plurality of pressing members.

(9) The casing may include a main body portion forming the insertion space and a through hole portion formed in the main body portion through which the pressing member penetrates.

According to this configuration, the main body of the casing can be formed into a thinner shape. As a result, the support device can be made more compact.

(10) When the pressing member is rotatably supported by the casing around a predetermined support shaft, and the casing includes a bracket provided on the outer surface of the main body and supporting the support shaft. There is.

According to this configuration, the support shaft can be supported with higher rigidity by the bracket while making the main body portion thin.

(11) The bracket may rotatably support the support shaft via a bearing.

According to this configuration, the pressing member can be rotated more smoothly. As a result, when a force that displaces the receiving portion to the outside of the insertion space acts on the receiving portion from the support object, the pressing member can be rotated more smoothly around the support shaft.

(12) In order to solve the above problems, the transport device according to a certain aspect of the present invention includes the support device and a transport mechanism for transporting the support device.

According to this configuration, it is possible to carry each of the support objects (molds, etc.) of different sizes without using complicated configurations such as sensors and actuators, and the support objects can be attached and detached with simpler work. A transport device having a support device can be realized.

The weight portion 36 is a portion provided on the pressing member 8, and the center of gravity of the pressing member 8 is set at a position deviated from the central axis L30 of the support shaft 30 supporting the pressing member 8 toward the first portion 31. It is configured as follows. In the present embodiment, the entire urging portion 34 is formed by the weight portion 36. The first portion 31 having the above configuration is continuous with the second portion 32.

When the pressing member 8 is viewed from the side, the second portion 32 is formed in a shape protruding from one edge portion of the first portion 31, and in the present embodiment, it is formed in a substantially rectangular shape. The second portion 32 forms a half portion of the pressing member 8. In the present embodiment, the second portion 32 is arranged closer to one of the pair of parallel edge portions 31a and 31b of the first portion 31 31b. Further, when the pressing member 8 is viewed from the side, the area of the second portion 32 is set to be smaller than the area of the first portion 31. With this configuration, the center of gravity of the pressing member 8 is located at the first portion 31.

Of the second portion 32 of the pressing member 8, the first edge portion 32a arranged so as to face one end (upper end) of the corresponding through hole portion 9a includes the received portion 37. The received portion 37 is a portion that can be received by the stopper portion 22 provided in the through hole portion 9a of the casing 7, and is formed by an elongated flat surface in the present embodiment. In the standby state, which is the state before the mold 100 is inserted into the support device 2, the received portion 37 is received by the stopper portion 22.

The pressing portion 35 is provided in the insertion space 17 to press the outer peripheral surface of the end shaft portion 120 of the mold 100, and is a portion of the pressing member 8 that comes into direct contact with the mold 100. The pressing portion 35 is formed on a first edge portion 32a of the second portion 32 and a second edge portion 32b of the edge portion of the second portion 32 adjacent to the first portion 32a. When the pressing member 8 is in the standby state, the pressing portion 35 faces the central axis L17 of the insertion space 17. The pressing portion 35 is configured to allow the end shaft portion 120 of the mold 100 inserted into the insertion space 17 to smoothly enter the insertion space 17 and to press the end shaft portion 120 inserted into the insertion space 17. have.

Specifically, the pressing portion 35 has a first linear portion 41, an arc-shaped portion 42, and a second linear portion 43.

The first linear portion 41 is configured so that the end shaft portion 120 can come into contact with the end shaft portion 120 when the end shaft portion 120 is inserted into the insertion space 17, and the end of the mold 103 of the mold 100. It is provided as a portion for pressing the shaft portion 120 (large diameter shaft portion 123). The first linear portion 41 is a linear portion provided on the first edge portion 32a of the pressing member 8. A part of the first edge portion 32a constitutes a stopper portion 22. The arcuate portion 42 is arranged so as to be continuous with the first linear portion 41.

The arc-shaped portion 42 is a surface formed in an arc shape with the central axis L30 of the support shaft 30 supporting the pressing member 8 as the central axis. When the diameter of the end shaft portion 120 inserted into the insertion space 17 is equal to or less than the first predetermined value, the arc-shaped portion 42 guides the insertion of the end shaft portion 120 (small diameter shaft portion 121) into the insertion space 17. However, the end shaft portion 120 after the insertion operation into the insertion space 17 is completed is provided as a portion that does not receive the end shaft portion 120. Further, when the diameter of the end shaft portion 120 inserted into the insertion space 17 is larger than the first predetermined value and less than the second predetermined value, the arcuate portion 42 has the end shaft portion 120 into the insertion space 17 ( It is provided as a portion that guides the insertion of the medium-diameter shaft portion 122) and presses the end shaft portion (medium-diameter shaft portion 122) after the insertion operation into the insertion space 17 is completed. In the present embodiment, the radius of curvature of the arcuate portion 42 is constant.

In the standby state, the arcuate portion 42 is curved so as to proceed toward the inside of the insertion space 17 (center axis L17 side) as it advances toward the inner side of the insertion space 17. That is, in the standby state, the distance between the arcuate portions 42 of the plurality of pressing members 8 becomes narrower as the insertion space 17 advances to the inner side. As a result, the end shaft portion 120 can be smoothly inserted between the plurality of pressing members 8. In the present embodiment, the arc-shaped portion 42 is formed over half or more of the second edge portion 32b, and extends over a wider range than the range where the second linear portion 43 is provided.

The second linear portion 43 is a linear surface extending along the tangential direction of one end portion (lower end portion in the standby state) of the arc-shaped portion 42 continuous with the second linear portion 43. The second linear portion 43 has an insertion space 17 when the diameter of the end shaft portion 120 inserted into the insertion space 17 is the first predetermined value, that is, when the small diameter shaft portion 121 is inserted into the insertion space 17. It is provided so as to receive the end shaft portion 121 after the insertion operation into the is completed.

In the standby state, the second linear portion 43 is arranged on the back side (lower end portion) of the insertion space 17 with respect to the arcuate portion 42. In the standby state, the second linear portion 43 extends parallel to the central axis L17 of the insertion space 17. Further, the second linear portion 43 is 90 degrees different from the first linear portion 41 in the direction around the support shaft 30.

Further, in the standby state, the distance between the second linear portions 43, 43 in the standby state of the pair of pressing members 81, 83 (82, 84) arranged at a pitch of 180 degrees in the insertion space 17 is substantially. The diameter is set to be substantially the same as the diameter of the small diameter shaft portion 121, and as described above, it is, for example, about 45 mm to 46 mm.

With the above configuration, as the end shaft portion 120 pressurizes the pressing portion 35 by inserting the end shaft portion 120 into the insertion space 17, the pressing portion 35 opposes the urging force F1 of the urging portion 34 and the insertion space 17 The pressing member 8 is supported by the casing 7 so as to allow the displacement toward the outside of the casing 7. In the following, the case where the pressing portion 35 presses the small diameter shaft portion 121, the case where the holding portion 35 presses the medium diameter shaft portion 122, and the case where the large diameter shaft portion 123 is pressed will be described as examples.

FIG. 6 is a cross-sectional view of a main portion for explaining the operation of mounting the mold 101 having the small diameter shaft portion 121 on the support device 2, and FIG. 6 (A) shows the small diameter shaft portion 121 attached to the casing 7. 6 (B) and 6 (C) show a state in which the small diameter shaft portion 121 is being inserted into the casing 7, and FIG. 6 (D) shows a state in which the small diameter shaft portion 121 is being inserted into the casing 7. It shows a state in which the insertion of the small diameter shaft portion 121 into the casing is completed.

With reference to FIG. 6A, the insertion of the small diameter shaft portion 121 into the insertion space 17 of the casing 7 is started by the hand of a robot arm or a worker or by using a hoist. At this time, normally, the central axis L120 of the small-diameter shaft portion 121 and the central axis L17 of the insertion space 17 are in a deviated state. Therefore, the small-diameter shaft portion 121 inserted into the insertion space 17 comes into contact with, for example, the arcuate portion 42 of some of the pressing members 81 among the plurality of pressing members 8 (81 to 84). At this time, the vector of the collision load F2 acting on the arcuate portion 42 of the pressing member 8 from the small diameter shaft portion 121 faces the rotation center of the pressing member 8 (that is, the central axis L30 of the support shaft 30). Therefore, it is suppressed that the rotational force for rotating the pressing member 8 is generated due to the collision between the small diameter shaft portion 121 and the arc-shaped portion 42.

Then, when the small diameter shaft portion 121 is further inserted into the inner side of the insertion space 17, the pressing member 81 in contact with the small diameter shaft portion 121 is as shown in FIGS. 6 (B) and 6 (C). By rotating around the support shaft 30 while being pushed by the small diameter shaft portion 121, the pressing portion 35 rotates toward the back side of the insertion space 17. As a result, the small diameter shaft portion 121 can enter the insertion space 17. That is, the pressing member 81 inserts the pressing portion 35 against the urging force F1 of the urging portion 34 as the end shaft portion 121 pressurizes the pressing portion 35 by inserting the end shaft portion 121 into the insertion space 17. It is displaced toward the outside of the space 17. Then, during the insertion of the small-diameter shaft portion 121 into the insertion space 17, the pressing member 81 is pressed into the inside of the insertion space 17 by the urging force F1 of the pressing member 81 in contact with the small-diameter shaft portion 121. To. That is, the small-diameter shaft portion 121 is centered (aligned) so that the central axis L120 of the small-diameter shaft portion 121 is brought closer to the central axis L17 of the insertion space 17. At this time, in the pressing member 81, the arcuate portion 42 of the pressing portion 35 is formed in an arc shape centered on the central axis L30 of the support shaft 30. Therefore, by arranging the central axis L120 of the end shaft portion 120 so as to overlap the central axis L17 of the insertion space 17, the pendulum-shaped pressing portion 35 is naturally restored by the urging force F1 of the urging portion 34. Return to the position (position in the standby state).

As a result, as shown in FIG. 6 (D), with the completion of the insertion of the small diameter shaft portion 121 into the insertion space 17, the small diameter shaft portion 121 becomes the second straight line of the pressing portion 35 of one or a plurality of pressing members 8. It is arranged so as to be received by the shape portion 43, and further, the spindle portion 110 is received by the main body portion 9. Further, the receiving portion 37 of each pressing member 8 is received by the stopper portion 22.

In the above description, the case where the small diameter shaft portion 121 does not come into contact with the first linear portion 41 of the pressing member 8 has been described. However, in some cases, as shown in FIG. 7A, the small diameter shaft portion 121 may initially come into contact with the first linear portion 41 of the pressing member 81. Even in this case, the small diameter shaft portion 121 rotates the pressing member 81 around the support shaft 30 by pushing down the pressing portion 35 while contacting the first linear portion 41. Then, as the amount of the small-diameter shaft portion 121 inserted into the insertion space 17 increases, the pressing member 81 brings the small-diameter shaft portion 121 closer to the central axis L17 side by the urging force F1. As a result, as shown in FIG. 7B, the small diameter shaft portion 121 comes into contact with the arcuate portion 42 of the pressing portion 35. Subsequent operations are the same as when the small diameter shaft portion 121 first contacts the arcuate portion 42 of the pressing member 81.

FIG. 8 is a cross-sectional view of a main portion for explaining the operation of mounting the mold 102 having the medium-diameter shaft portion 122 on the support device 2, and FIG. 8 (A) shows the medium-diameter shaft portion to the casing 7. The state in which the 122 is started to be inserted is shown, FIG. 8 (B) shows the state in which the medium-diameter shaft portion 122 is being inserted into the casing 7, and FIG. 8 (C) shows the inside into the casing 7. It shows a state in which the insertion of the radial shaft portion 122 is completed.

With reference to FIG. 8A, the operation of inserting the medium-diameter shaft portion 122 into the insertion space 17 is substantially the same as the operation of inserting the small-diameter shaft portion 121 into the insertion space 17. Hereinafter, the insertion operation of the medium-diameter shaft portion 122 into the insertion space 17 will be described mainly different from the insertion operation of the small-diameter shaft portion 121 into the insertion space 17. Specifically, when the medium-diameter shaft portion 122 is inserted into the insertion space 17 by the hand of a robot arm or a worker or by using a hoist, the medium-diameter shaft portion 122 may hold, for example, a plurality of presses. A part of the member 8 comes into contact with the arcuate portion 42 of the pressing member 81.

Then, when the medium-diameter shaft portion 122 is further inserted into the inner side of the insertion space 17, the pressing member 81 in contact with the medium-diameter shaft portion 122 is subjected to the medium-diameter shaft portion as shown in FIG. 8 (B). By rotating around the support shaft 30 while being pushed by 122, the pressing portion 35 rotates toward the back side of the insertion space 17. That is, in the pressing member 81, as the medium-diameter shaft portion 122 pressurizes the pressing portion 35 by inserting the medium-diameter shaft portion 122 into the insertion space 17, the pressing portion 35 resists the urging force F1 of the urging portion 34. Then, the insertion space 17 is displaced toward the outside. Then, during the insertion of the medium-diameter shaft portion 122 into the insertion space 17, the pressing member 81 is inserted into the insertion space by the urging force F1 by the urging portion 34 of the pressing member 81 in contact with the medium-diameter shaft portion 122. It is displaced inward of 17. That is, the mold 102 is centered (aligned) so that the central axis L120 of the medium-diameter shaft portion 122 is brought closer to the central axis L17 of the insertion space 17. Then, the arcuate portion 42 of the pressing portion 35 of the other pressing member 8 that was not in contact with the mold 102 also comes into contact with the medium-diameter shaft portion 122, so that the pressing member 8 moves to the back side of the insertion space 17. Rotate.

As a result, as shown in FIG. 8C, when the insertion of the medium-diameter shaft portion 122 into the insertion space 17 is completed, the medium-diameter shaft portion 122 becomes an arcuate portion of the pressing portion 35 of all the pressing members 8. Arranged so that it can be received by 42. Further, the spindle portion 110 of the medium diameter shaft portion 122 is received by the casing 7. Then, when the pressing portion 35 presses the medium-diameter shaft portion 122, each pressing member 8 is in contact with the medium-diameter shaft portion 122 by the urging force F1 of the urging portion 34, although it is not in contact with the stopper portion 22. By being done, it is maintained in a fixed position.

On the other hand, when the medium-diameter shaft portion 122 is removed from the support device 2, the medium-diameter shaft portion 122 is pulled up from the insertion space 17 while rubbing against each arc-shaped portion 42. At this time, as shown in FIG. 8B, the arcuate portion 42 of each pressing member 8 is formed in a shape centered on the rotation center line of the pressing member 8 (center axis L30 of the support shaft 30). .. As a result, it is possible to prevent each pressing member 8 from swinging around the corresponding support shaft 30. Then, when the medium-diameter shaft portion 122 is pulled up to the extent that the medium-diameter shaft portion 122 does not come into contact with the arc-shaped portion 42, the pressing member 8 rotates around the support shaft 30 by the urging force F1 of the urging portion 34. , The receiving portion 37 returns to the position where it can be received by the stopper portion 22 (the position in the standby state).

In the above description, the case where the medium-diameter shaft portion 122 does not come into contact with the first linear portion 41 of the pressing member 8 has been described. However, in some cases, as shown in FIG. 9A, the medium-diameter shaft portion 122 may first come into contact with the first linear portion 41 of the pressing member 81. Even in this case, the medium-diameter shaft portion 122 pushes down the pressing portion 35 while contacting the first linear portion 41, thereby rotating the pressing member 8 around the support shaft 30. Then, as the amount of the medium-diameter shaft portion 122 inserted into the insertion space 17 increases, the pressing member 81 brings the medium-diameter shaft portion 122 closer to the central axis L17 side by the urging force F1. As a result, as shown in FIG. 9B, the medium-diameter shaft portion 122 comes into contact with the arc-shaped portion 42 of the pressing portion 35 of the pressing member 81, and the arc-shaped portion of the pressing portion 35 of the other pressing member 8 is formed. It also contacts 42. Subsequent operations are the same as when the medium-diameter shaft portion 122 first contacts the arc-shaped portion 42 of the pressing member 8.

FIG. 10 is a cross-sectional view of a main portion for explaining the operation of mounting the mold 103 having the large-diameter shaft portion 123 on the support device 2, and FIG. 10 (A) shows the large-diameter shaft portion to the casing 7. The state in which the 123 is started to be inserted is shown, and FIG. 10 (B) shows the state in which the insertion of the large-diameter shaft portion 123 into the casing 7 is completed.

With reference to FIG. 10A, the operation of inserting the large-diameter shaft portion 123 into the insertion space 17 is substantially the same as the operation of inserting the small-diameter shaft portion 121 into the insertion space 17. Hereinafter, the insertion operation of the large-diameter shaft portion 123 into the insertion space 17 will be described mainly different from the insertion operation of the small-diameter shaft portion 121 into the insertion space 17. Specifically, when the large-diameter shaft portion 123 is inserted into the insertion space 17 by the hand of a robot arm or a worker or by using a hoist, the large-diameter shaft portion 123 is a pressing member 8 of each holding member 8. It comes into contact with the first linear portion 41 of the pressing portion 35.

Then, when the large-diameter shaft portion 123 is further inserted into the inner side of the insertion space 17, each pressing member 8 rotates around the support shaft 30 while being pushed by the large-diameter shaft portion 123, as shown in FIG. 10 (B). By rotating, the pressing portion 35 rotates toward the back side of the insertion space 17. That is, in the pressing member 8, the pressing portion 35 resists the urging force F1 of the urging portion 34 as the large-diameter shaft portion 123 pressurizes the pressing portion 35 by inserting the large-diameter shaft portion 123 into the insertion space 17. Then, the insertion space 17 is displaced toward the outside. As a result, with the completion of the insertion of the large-diameter shaft portion 123 into the insertion space 17, the large-diameter shaft portion 123 is arranged so as to be received by the first linear portion 41 of the pressing portion 35 of all the pressing members 8. To. Further, the spindle portion 110 is received by the main body portion 9. Then, when the pressing portion 35 presses the large-diameter shaft portion 123, each pressing member 8 receives the large-diameter shaft portion 123 by the urging force F1 of the urging portion 34, although it is not in contact with the stopper portion 22. By being done, it is maintained in a fixed position.

On the other hand, when the large-diameter shaft portion 123 is removed from the support device 2, the large-diameter shaft portion 123 is pulled up from the insertion space 17 while rubbing against each of the first linear portions 41. Then, as the large-diameter shaft portion 123 is pulled up from the insertion space 17, the pressing member 8 rotates around the support shaft 30 by the urging force F1 of the urging portion 34, so that the received portion 37 becomes the stopper portion 22. Return to the position where it can be received (the position in the standby state).

As described above, according to the present embodiment, as the end shaft portion 120 pressurizes the pressing portion 35 by inserting the end shaft portion 120 into the insertion space 17, the pressing portion 35 is attached by the urging portion 34. It is possible to displace to the outside of the insertion space 17 against the force F1. As a result, for example, when the medium-diameter shaft portion 122 or the large-diameter shaft portion 123 of the molds 102 and 103 is inserted into the casing 7, the holding portion 35 is directed to the outside of the insertion space 17 by the end shaft portions 122 and 123. By being pushed, the end shafts 122 and 123 are displaced to positions suitable for holding. On the other hand, for example, when the small-diameter shaft portion 121 of the mold 101 is inserted into the casing 7, the holding portion 35 can hold the small-diameter shaft portion 121 while remaining in a position suitable for holding the small-diameter shaft portion 121. .. With such a configuration, regardless of the size of the end shaft portion 120 inserted into the insertion space 17, the end shaft portion 120 is appropriately pressed by the pressing portion 35, so that the molds 101, 102, 103 can be held in a stable posture. I can support it. That is, it is possible to carry the end shaft portions 121, 122, and 123 of different sizes, respectively. Further, the support device 2 can support the transfer of molds 101, 102, and 103 of different sizes without using a complicated configuration such as a sensor or an actuator. Further, the pressing member 8 is displaced by the force applied from the molds 101, 102, 103 to the pressing portion 35 as the molds 101, 102, 103 are inserted into the insertion space 17, so that the pressing portion 35 is positioned appropriately. It is a configuration that rotates and moves to. Therefore, it is not necessary to attach a dedicated member such as an attachment to fill the gap between the end shaft portions 121, 122, 123 and the holding portion 35. As a result, the molds 101, 102, and 103 can be attached to and detached from the support device 2 with a simpler operation. Based on the above, it is possible to carry the molds 101, 102, 103 of different sizes without using complicated configurations such as sensors and actuators, and the molds 101, 102, 103 can be carried out with simpler work. It is possible to realize a support device 2 that can be attached and detached.

Further, according to the present embodiment, the pressing portion 35 is arranged at a position suitable for pressing the end shaft portions 121, 122, 123 by a simple and compact configuration in which the pressing member 8 rotates around the support shaft 30. be able to.

Further, according to the present embodiment, the urging portion 34 includes a weight portion 36 provided on the pressing member 8. According to this configuration, the weight portion 36 can act on the pressing portion 35 with a moment around the support shaft 30. By providing the weight portion 36 in this way, the urging force F1 can be applied to the pressing portion 35 without using a complicated configuration such as an actuator.

Further, according to the present embodiment, the pressing portion 35 includes an arc-shaped portion 42 having the central axis L30 of the support shaft 30 as the central axis. According to this configuration, when the end shaft portion 120 is inserted into the insertion space 17 and the end shaft portion 120 collides with the arcuate portion 42, the normal force acting on the pressing member 8 is applied to the central axis L30 of the support shaft 30. It becomes a force in the direction of passing. That is, the direction of the vector of the collision load F2 acting on the pressing member 8 from the end shaft portion 120 is the direction passing through the central axis L30 of the support shaft 30. As a result, the pressing member 8 is prevented from causing an unnecessary rotational movement due to the collision with the end shaft portion 120.

Further, according to the present embodiment, the pressing member 8 is configured to be received by the stopper portion 22 when the pressing portion 35 advances by a predetermined amount inside the insertion space 17. According to this configuration, the stopper portion 22 can regulate the displacement of the pressing portion 35 more than necessary.

Further, according to the present embodiment, the pressing portion 35 is configured to be able to selectively press the small diameter shaft portion 121, the medium diameter shaft portion 122, and the large diameter shaft portion 123, and the pressing portion 35 is configured. When receiving the small diameter shaft portion 121, the pressing member 8 is configured to be received by the stopper portion 22. According to this configuration, when the pressing portion 35 receives the small diameter shaft portion 121, the pressing member 8 does not have to rotate around the support shaft 30, or the amount of rotation of the pressing member 8 can be reduced. With such a configuration, the work of inserting the small diameter shaft portion 121 into the insertion space 17 can be simplified.

Further, according to the present embodiment, the insertion space 17 is opened upward in the vertical direction, and the support shaft 30 is arranged in the horizontal direction. According to this configuration, when the end shaft portion 120 is inserted into the insertion space 17 along the vertical direction, the pressing member 8 can rotate around the support shaft 30 more smoothly due to gravity.

Further, according to the present embodiment, a plurality of pressing members 8 are provided so as to cooperate with each other and sandwich the end shaft portions 120. According to this configuration, the end shaft portion 120 can be supported in a more stable posture by the plurality of pressing members 8.

Further, according to the present embodiment, the casing 7 includes a main body portion 9 forming the insertion space 17 and a through hole portion 9a formed in the main body portion 9 through which the pressing member 8 penetrates. According to this configuration, the main body 9 of the casing 7 can be formed into a thinner shape. As a result, the support device 2 can be made more compact.

Further, according to the present embodiment, the casing 7 includes a bracket 10 provided on the outer surface of the main body 9 and supporting the support shaft 30. According to this configuration, the support shaft 30 can be supported by the bracket 10 with higher rigidity while the main body portion 9 has a thin shape.

Further, according to the present embodiment, the bracket 10 rotatably supports the support shaft 30 via the bearing 23. According to this configuration, the pressing member 8 can be rotated more smoothly. As a result, when a force that displaces the pressing portion 35 to the outside of the insertion space 17 acts on the pressing portion 35 from the end shaft portion 120, the pressing member 8 can be rotated more smoothly around the support shaft 30.

The present invention is not limited to the above configuration, and various modifications can be made within the scope of the claims. For example, it may be changed as follows. In the following, the points different from the above-described embodiment will be mainly described, and the same reference numerals are given to the drawings in the same configuration, and detailed description thereof will be omitted.

(1) In the above-described embodiment, a mode in which the arcuate portion 42 is formed on the pressing member 8 has been described as an example. However, this does not have to be the case. For example, as shown in FIG. 11A, a pressing member 8 including a pressing portion 35 provided with a chamfered portion 45 may be formed instead of the arc-shaped portion 42. The chamfered portion 45 is a surface formed linearly so as to connect the first linear portion 41 and the second linear portion 43, and is inclined with respect to the first linear portion 41 and the second linear portion 43. doing. Further, as shown in FIG. 11B, an arcuate portion 42A may be provided instead of the arcuate portion 42. The central axis L42A of the arcuate portion 42A of the pressing member 8 is offset from the central axis L30 of the support shaft 30.

However, in the case of the holding member 8 including the chamfered portion 45 shown in FIG. 11A, when the end shaft portion 120 collides with the chamfered portion 45, the vector of the collision load F2 faces the direction orthogonal to the chamfered portion 45. However, it may not pass through the central axis L30 of the support shaft 30. In this case, one component F21 of the vector of the collision load F2 acts as a force for rotating the pressing member 8, and the pressing member 8 swings around the support shaft 30.

When the central axis L42A of the arcuate portion 42A of the pressing member 8 shown in FIG. 11B is deviated from the central axis L30 of the support shaft 30, the following operation occurs. That is, when the end shaft portion 120 collides with the arcuate portion 42A, the vector of the collision load F2 faces the direction orthogonal to the portion of the arcuate portion 42A that collides with the end shaft portion 120, but is the center of the support shaft 30. The direction is different from the direction passing through the axis L30. In this case, one component F21'of the vector of the collision load F2 acts as a force for rotating the pressing member 8. However, the swing of the pressing member 8 around the support shaft 30 is slight.

As described above, even in the configurations shown in FIGS. 11A and 11B, the end shaft portion 120 can be inserted into the insertion space 17 while being centered in the insertion space 17.

(2) Further, in the above-described embodiment, the configuration in which the pressing member 8 is a pendulum type configuration that rotates around the support shaft 30 has been described as an example. However, it is not limited to this configuration. In the pressing member 8, the pressing portion 35 presses the pressing portion 35 by inserting the end shaft portion 120 into the insertion space 17, and the pressing portion 35 moves toward the outside of the insertion space 17 against the urging force F1. It suffices if it is supported by the casing 7 so as to allow displacement to.

For example, as shown in FIG. 12, a slide type pressing member 8B may be used. In this case, the pressing member 8B is supported by the bracket 10B so as to be linearly movable in a direction (horizontal direction) orthogonal to the central axis L17 of the insertion space 17. The pressing member 8B further has an urging portion 34B such as a coil spring supported by the bracket 10B in addition to the plate-shaped member on which the pressing portion 35 is formed. The urging portion 34B generates an urging force F1 that urges the pressing portion 35 toward the inside of the insertion space 17. Further, the pressing member 8B is formed with a receiving portion 37B that can be received by the stopper portion 22B formed at the edge portion of one end portion of the through hole portion 9a. The received portion 37B is, for example, a stepped portion formed adjacent to the first linear portion 41.

With the above configuration, the pressing member 8B performs the same operation as the pressing member 8 by acting on the urging force F1 by the urging portion 34B.

More specifically, in the transport device 1A, in the support device 2, the pressing members 8 arranged so as to face each other across the central axis L17 of the insertion space 17 are obliquely inclined by 45 degrees with respect to the transport direction T. It is installed in the transport mechanism 3 in a state of being lined up along the direction.

In FIGS. 13 and 14, the holding member arrangement line S, which is a line in which the holding members 8 arranged so as to face each other across the central axis L17 of the insertion space 17 of the main body 9 in the transport device 1A, is represented by a alternate long and short dash line. Shown. The pressing member arrangement line S is configured as a line extending horizontally along an oblique direction inclined by 45 degrees with respect to the conveying direction T.

Further, in each support device 2 in the transfer device 1A, two pressing member arrangement lines S are formed. The pressing member 81 and the pressing member 83 are arranged side by side on one pressing member arrangement line S. The pressing member 82 and the pressing member 84 are arranged side by side on the other pressing member arrangement line S. Therefore, the urging portion 34 and the pressing portion 35 of the pressing member 81 and the urging portion 34 and the pressing portion 35 of the pressing member 83 are arranged side by side along the same pressing member arrangement line S. The urging portion 34 and the pressing portion 35 of the pressing member 82 and the urging portion 34 and the pressing portion 35 of the pressing member 84 are arranged side by side along the same pressing member arrangement line S. Further, the urging portion 34 of the pressing member 81 and the urging portion 34 of the pressing member 83 are arranged at point-symmetrical positions about the central axis L17 of the insertion space 17, and the pressing portion 35 of the pressing member 81 and the pressing member The holding portion 35 of 83 is arranged at a point-symmetrical position about the central axis L17 of the insertion space 17. Then, the urging portion 34 of the pressing member 82 and the urging portion 34 of the pressing member 84 are arranged at point-symmetrical positions about the central axis L17 of the insertion space 17, and the pressing portion 35 of the pressing member 82 and the pressing member The holding portion 35 of 84 is arranged at a point-symmetrical position about the central axis L17 of the insertion space 17.

When the mold 100 is mounted on the support device 2 of the transport device 1A described above, that is, when the end shaft portion 120 is inserted into the insertion space 17 of the casing 7, from the viewpoint of improving work efficiency, for example, A mold carry-in hoist, which is a carry-in hoist of the mold 100, is used. This mold carrying hoist is provided with a chuck portion that detachably grips the mold 100, and is configured to vertically drive the mold 100 gripped by the chuck portion in the vertical direction and along the rail. It is configured to travel horizontally. Further, the rail on which the mold carrying hoist travels is installed so as to extend in parallel with the transport direction T of the mold 100 by the transport mechanism 3 from the viewpoint of improving the efficiency of the installation space or improving workability. Ru. The hoist for carrying in the mold is operated by, for example, an operator to hold and release the mold 100 at the chuck portion, raise and lower the chuck portion holding the mold 100, and rail. The running operation is performed along the line.

When the mold 100 is mounted on the support device 2, the orbital portion 5 of the transport mechanism 3 is stopped, that is, the support device 2 is stopped and does not move, and the mold carrying hoist is used. The mold 100 is carried in. At this time, first, the hoist for carrying in the mold grips the mold 100 arranged at a predetermined position by the chuck portion based on the operation of the worker, and raises the chuck portion holding the mold 100. To operate. As a result, the mold 100 is suspended from the mold carry-in hoist. In this state, the traveling operation of the mold carrying-in hoist traveling along the rail extending in parallel with the conveying direction T is performed.

The mold carry-in hoist on which the mold 100 is suspended stops when it travels along the rail to the upper part of the casing 7 of the support device 2 to which the mold 100 is mounted. Then, when the traveling operation of the hoist for carrying in the mold is stopped, the hoist that grips the mold 100 operates so as to lower the chuck portion. When the mold 100 gripped by the chuck portion is lowered and the end shaft portion 120 of the mold 100 is inserted into the insertion space 17 of the casing 7 of the support device 2, the grip of the mold 100 by the chuck portion is released. .. By inserting the end shaft portion 120 of the mold 100 into the insertion space 17, the mounting of the mold 100 on the support device 2 is completed. When the mold 100 is mounted on the support device 2, the track portion 5 of the transport mechanism 3 is driven by the drive source 4, and the mold 100 supported by the support device 2 is transported along the transport direction T. The mold carry-in hoist that has released the grip of the mold 100 travels along the rail with the chuck portion raised, and moves to a predetermined place where the next mold 100 to be carried in is arranged. ..

As described above, when the end shaft portion 120 of the mold 100 is inserted into the insertion space 17, the mold carrying hoist running along the rail extending parallel to the transport direction T is stopped. Will be. Therefore, when the mold loading hoist stops traveling, the mold 100 suspended in the mold loading hoist swings back and forth along the direction parallel to the transport direction T due to inertia. It will be. The mold 100 is suspended from a hoist for carrying in the mold, and there is no other member or the like that regulates the above-mentioned shaking in the space around the mold 100. Therefore, the above-mentioned shaking is maintained for a while. It will continue.

According to the above, even when the gripped mold 100 is lowered and the end shaft portion 120 thereof is inserted into the insertion space 17 after the running of the mold carrying hoist is stopped, the mold 100 is moved back and forth along the direction parallel to the transport direction T. The shaking of the shaking mold 100 will continue. Then, when the end shaft portion 120 of the swayed mold 100 is inserted into the insertion space 17 of the support device 2, the end shaft portion 120 sways with respect to the support device 2 in a direction parallel to the transport direction T. However, it becomes easier to contact. When the end shaft portion 120 comes into contact with the support device 2, the shaking of the mold 100 is suppressed.

As described above, when the end shaft portion 120 is inserted into the insertion space 17 using the mold carrying hoist, the end shaft portion 120 is parallel to the support device 2 in the transport direction T. It becomes easy to come into contact while swinging along the direction. In this case, in the transport device 1A, the end shaft portion 120 is a part of the chamfered portion 18 of the main body portion 9 of the casing 7 and is in a direction parallel to the transport direction T in the chamfered portion 18 with respect to the support device 2. At the end side portions 18a in the transport direction, which are the portions located on both end sides, the contact is facilitated (see FIG. 14). When the end shaft portion 120 comes into contact with the support device 2 at the end portion side portion 18a in the transport direction in the chamfered portion 18 of the main body portion 9, the shaking of the mold 100 is immediately stopped. Then, the end shaft portion 120 is easily and smoothly inserted into the insertion space 17 in a state where the shaking along the direction parallel to the transport direction T of the mold 100 has subsided.

In the transport device 1A, in the support device 2, the pressing members 8 arranged so as to face each other with the central axis L17 of the insertion space 17 interposed therebetween are arranged along an oblique direction inclined by 45 degrees with respect to the transport direction T. In this state, it is installed in the transport mechanism 3. Therefore, when the end shaft portion 120 abuts against the support device 2 while swinging along the direction parallel to the transport direction T, the end shaft portion 120 contacts the support device 2 with the chamfered portion 18 of the main body portion 9. The contact is made at the end side portion 18a in the transport direction in the above, and the shaking of the mold 100 is suppressed. Therefore, it is suppressed that the end shaft portion 120 of the mold 100 swinging along the direction parallel to the transport direction T first comes into contact with the pressing portion 35 of the pressing member 8, and the pressing member 8 swings excessively. It is also possible to suppress the occurrence of a state in which it ends up. As a result, the end shaft portion 120 is easily and smoothly inserted into the insertion space 17.

In addition, the support mechanism 2 is in a state where the pressing members 8 arranged so as to face each other with the central axis L17 of the insertion space 17 are arranged along the directions parallel to and perpendicular to the transport direction T, respectively. When installed in 3, the end shaft portion 120 is likely to come into contact with the support device 2 first by the pressing member 8. That is, in this case, the end shaft portion 120 of the mold 100 that sways along the direction parallel to the transport direction T first contacts the pressing portions 35 of the pressing members 8 arranged along the direction parallel to the transport direction T. It will be easier. When the end shaft portion 120 of the mold 100 swinging along the direction parallel to the transport direction T comes into contact with the holding portion 35 of the pressing member 8, excessive vibration of the pressing member 8 occurs, and the end shaft portion 120 Insertion into the insertion space 17 becomes difficult. In particular, when the end shaft portion 120 is configured as the small diameter shaft portion 121, a state in which it becomes difficult to insert the end shaft portion 120 into the insertion space 17 due to excessive shaking of the pressing member 8 is likely to occur. ..

However, in the transport device 1A, the support device 2 is installed in the transport mechanism 3 in a state where the pressing members 8 facing each other across the central axis L17 are lined up along a direction obliquely 45 degrees with respect to the transport direction T. ing. Therefore, the end shaft portion 120 of the mold 100 that sways along the direction parallel to the transport direction T is not on the holding member 8 but on the chamfered portion 18 of the main body 9 in the transport direction end side with respect to the support device 2. The contact is made at the portion 18a, and the shaking of the mold 100 is suppressed. As a result, the end shaft portion 120 is easily and smoothly inserted into the insertion space 17.

The present invention can be applied as a support device and a transport device including the support device.
