On the other hand, if it is determined in step ST61 that the pallet P has not been transported to the predetermined position, the lid opening control means 64 does not execute the processing after step ST62 and opens the container. The process ends.

If it is determined in step ST61 that the pallet P has been conveyed to a predetermined position,
As shown in FIG. 9, the suction control unit 641 inserts the nozzle 611 into the communication hole P3 of the pallet P by causing the linear actuator 612B to advance the frame 612A relative to the pallet P (see the thick arrow in the figure). . The suction control unit 641 sucks the container 20 placed on the pallet P through the communication hole P3 of the pallet P with a suction device (not shown) connected to the nozzle 611, thereby causing the container 20 to move to the pallet. It fixes to P (ST62: container suction step).

The transport control unit 951 controls the transport mechanism 91 and transports the cover C to the predetermined standby position by the transport mechanism 91. Specifically, the transport control unit 951 moves the plate 933 with the covering moving mechanism 94, thereby covering the transport mechanism 91 with the transport mechanism 91 to a predetermined standby position where the cover holding unit 93 can hold the three covers C. Transport C.
The covering control unit 952 controls the covering mechanism 92 to cover the container 20 with the cover C transported by the transport mechanism 91. Specifically, the covering controller 952 covers the container 20 by covering the container 20 with the covering mechanism 92 by lowering the cover C toward the upper surface of the container 20.

FIG. 21 is a diagram illustrating a flowchart of the cover covering process executed by the cover covering apparatus.
When covering the container 20 with the cover coating apparatus 9, the coating control means 95 executes steps ST91 to ST93 as shown in FIG. 21 according to a predetermined program stored in the memory.
Hereinafter, details of steps ST91 to ST93 will be described with reference to the drawings.

  First, the covering control means 95 detects whether or not the pallet P has been transported to a predetermined position (see FIG. 17) on the conveyor 2 (ST91: pallet detection step). If it is determined in step ST91 that the pallet P has been transported to a predetermined position, the covering control unit 95 executes the processing after step ST92. On the other hand, when it is determined in step ST91 that the pallet P has not been transported to the predetermined position, the covering control unit 95 performs the cover covering process without executing the processes after step ST92. finish.

If it is determined in step ST91 that the pallet P has been conveyed to a predetermined position,
The transport control unit 951 transports the cover C by the transport mechanism 91 to a predetermined standby position where the cover holding unit 93 can hold the three covers C by moving the plate 933 by the covering moving mechanism 94 ( ST92: Cover conveyance step).

FIG. 22 is a diagram showing the cover coating apparatus in a state where the cover is held by the cover holding means. Specifically, FIG. 22 is a view of the cover coating device 9 as viewed from the + X-axis direction side.
Next, the covering controller 952 executes the cover covering step of ST93. In this cover covering step, first, the covering control unit 952 moves the plate 933 by the covering moving mechanism 94 to move it to the predetermined standby position where the cover C is transported in the cover transporting step ST92. The cover C is held by the cover holding means 93 by sucking the cover C through the through holes 931B and 932B with a suction device (not shown) connected to the cylindrical portions 931C and 932C.
Then, the covering controller 952 moves the cover holding means 93 above the pallet P by moving the plate 933 by the covering moving mechanism 94 as shown in FIG.

Here, the end of the cover C on the container body 201 side is fitted with the recess 931A of the one-end holding means 931, and the end of the cover C on the lid member 202 side is fitted with the recess 932A of the other-end holding means 932. To do. In other words, the one end holding means 931 and the other end holding means 932 include recesses 931 </ b> A and 932 </ b> A that accommodate the cover C when holding the cover C. The recesses 931A and 932A have a shape that covers the upper surface and side surfaces of the cover C.
In the present embodiment, the one-end holding means 931 and the other-end holding means 932 include the recesses 931A and 932A that receive the cover C when holding the cover C. However, this may not be provided. In short, the one end holding means only needs to be able to hold one end of the cover, and the other end holding means need only be able to hold the other end of the cover.

Further, the hinge covering portion C11 of the cover C is fitted to the concave portion 933A1 of the cylindrical shaft body 933A. In other words, the cover covering device 9 includes a cylindrical shaft body 933A as a central holding means that holds the central portion of the cover C, and the cover holding means 93 holds the cylindrical shaft body 933A fixedly.
In the present embodiment, the cover coating apparatus 9 includes a central holding unit that holds the central portion of the cover C, but may not include this. In short, the cover coating apparatus only needs to include one end holding means and the other end holding means.

FIG. 23 is a diagram showing the cover coating apparatus in a state where the cover holding means is lowered.
Next, as shown in FIG. 23, the covering control unit 952 moves the cover holding means 93 by the covering moving mechanism 94 to lower the cover C toward the upper surface of the container 20 (see FIG. 23). (See middle thick arrow).

  Here, as described above, the one end holding means 931 is swingably attached to the plate 933 via the spring 931D and the damper 931E. As described above, the other end holding means 932 is swingably attached to the plate 933 via the spring 932D and the damper 932E. In other words, the cover holding means 93 supports the one end holding means 931 and the other end holding means 932 so as to be able to advance and retreat toward the upper surface of the container 20.

Accordingly, when the cover C is lowered and covered by the covering control unit 952 toward the upper surface of the container 20, when the cover C is caught on the end of the container 20, the one end holding means 931 and the other end holding means 932 Ascends away from 20. Further, since the cover holding means 93 fixes and supports the cylindrical shaft body 933A that holds the hinge covering portion C11 of the cover C, the cover control portion 952 lowers the cover C toward the upper surface of the container 20 and covers it. When covering, the cylindrical shaft body 933 </ b> A does not rise away from the container 20.
In other words, when the cover C is lowered and covered by the covering control unit 952 toward the upper surface of the container 20, if the cover C is caught on the end of the container 20, the cover C separates both ends from the container 20. It will bend and bend like this (see FIG. 23).

  In this embodiment, the cover holding means 93 supports the one end holding means 931 and the other end holding means 932 so as to be able to advance and retreat toward the upper surface of the cover C, but only the one end holding means 931 is supported on the upper surface of the container 20. The other end holding means 932 may be supported so as to be movable back and forth toward the upper surface of the container 20. In short, the cover holding means may support at least one of the one end holding means and the other end holding means so as to be able to advance and retreat with respect to the upper surface of the container.

FIG. 24 is a diagram showing the cover coating apparatus in a state where the cover holding means is further lowered.
Next, as shown in FIG. 24, the covering control unit 952 moves the cover holding means 93 by the covering moving mechanism 94 to further lower the cover C toward the upper surface of the container 20 and cover it ( (See thick arrow in the figure).
The covering control unit 952 can cover the container 20 with the cover C that has been bent by releasing the suction of a suction device (not shown) connected to the cylindrical portions 931C and 932C.
Thereafter, the covering control means 95 controls the covering mechanism 92 to return to the initial state (state shown in FIG. 17), and again executes the above-described step ST91 for the next pallet P, thereby performing steps ST91 to ST91. Repeat ST93.

<Cover handling device>
FIG. 25 is a perspective view showing a cover handling device. FIG. 26 is a cross-sectional view showing a cover handling device.
The cover handling device 10 lowers the cover C toward the upper surface of the container 20 by the cover coating device 9 and covers the cover C. Then, the cover handling device 10 causes the cover C to adhere to the container 20 by handling the upper surface of the cover C. As shown in FIGS. 25 and 26, the cover handling device 10 is a roller for one end that handles the upper surface portion C1 of the cover C from the center portion of the cover C toward one end portion (end portion of the container main body 201). The mechanism 101 and the roller mechanism 102 for the other end which handles the upper surface part C1 of the cover C toward the other end part (end part of the cover member 202) from the center part of the cover C are provided. The cover handling apparatus 10 includes a roller head 103 that supports the one-end roller mechanism 101 and the other-end roller mechanism 102, and a handling moving mechanism 104 that raises and lowers the roller head 103.

The one-end roller mechanism 101 rotatably supports the one-end handling member 101A that is in contact with one end side of the upper surface C1 of the cover C and the one-end handling member 101A around the X axis. And a support member 101B for one end provided on the other end side of the cover C with respect to the center portion.
Thus, the end support member 101B is orthogonal to the handle direction (−Y-axis direction) of the end member 101A and is rotatable about the axis parallel to the upper surface C1 of the cover C. It is pivotally supported.
Therefore, in this embodiment, the one-end roller mechanism 101 functions as one-end handling means.

The one-end handling member 101A is provided at a rod-like member 101A1 formed in a prismatic shape, and at the distal end portion (end portion on the −Z-axis direction side) of the rod-like member 101A1, and is rotatable around the X axis (center axis). And a cylindrical roller 101A2 supported by a shaft. The one end handling member 101A has the side surface of the roller 101A2 in contact with the upper surface portion C1 of the cover C.

Here, as described above, the first housing cover portion C14 and the second housing cover portion C15 are formed so as to protrude upward. Further, the second housing cover C15 is formed so as to protrude upward from the first housing cover C14.
Therefore, the roller 101A2 is configured by combining a large-diameter roller that comes into contact with the first housing cover C14 and a small-diameter roller that comes into contact with the second housing cover C15.

  In the present embodiment, the one end handling member 101A employs the configuration including the rod-shaped member 101A1 and the roller 101A2, but other configurations may be employed. For example, the handling member for one end may be provided with a columnar member instead of the roller, and this columnar member may be fixed to the tip of the rod-shaped member. In short, the handling member for one end only needs to be in contact with one end of the upper surface of the cover and can handle the upper surface of the cover from the center of the cover toward the one end.

  In the present embodiment, the one-end roller mechanism 101 (one-end handling means) employs a configuration including the one-end handling member 101A and the one-end shaft support member 101B, but other configurations are also employed. May be. In short, the one end handling means only needs to be able to handle the upper surface of the cover from the central portion of the cover toward the one end portion.

The other end roller mechanism 102 rotatably supports the other end handling member 102A that contacts the other end side of the upper surface C1 of the cover C and the other end handling member 102A around the X axis. The other end shaft support member 102 </ b> B is provided on one end side of the cover C with respect to the center portion of the cover C.
In this manner, the other end shaft support member 102B is orthogonal to the handling direction (+ Y-axis direction) of the other end handling member 102A, and the other end handling member 102A is rotated about an axis parallel to the upper surface portion C1 of the cover C. It is pivotally supported.
Therefore, in the present embodiment, the other end roller mechanism 102 functions as the other end handling means.

The other end handling member 102A is provided at a rod-like member 102A1 formed in a prismatic shape, and at the distal end portion (end portion on the −Z-axis direction side) of the rod-like member 102A1, and is rotatable around the X axis (center axis). And a cylindrical roller 102A2 that is supported by the shaft. The other end handling member 102A has the side surface of the roller 102A2 in contact with the upper surface portion C1 of the cover C.
The base end (the end on the + Z-axis direction side) of the rod-shaped member 102A1 protrudes vertically above the roller head 103 through a slit 103A formed in the roller head 103, and is fixed to the roller head 103 through a spring 102A3. Has been.

  In the present embodiment, the other end handling member 102A employs the configuration including the rod-shaped member 102A1 and the roller 102A2, but other configurations may be employed. For example, the handling member for the other end may be provided with a columnar member instead of the roller, and the columnar member may be fixed to the tip of the rod-shaped member. In short, the other end handling member only needs to be in contact with the other end of the upper surface of the cover and handle the upper surface of the cover from the center of the cover toward the other end.

  In the present embodiment, the other end roller mechanism 102 (the other end handling means) employs a configuration including the other end handling member 102A and the other end pivot support member 102B. The configuration may be adopted. In short, the other end handling means only needs to be able to handle the upper surface of the cover from the center of the cover toward the other end.

Therefore, the roller head 103 functions as a handling head that supports the one end support member 101B and the other end support member 102B.
FIG. 26 is a partial cross-sectional view of the cover handling device 10 (roller head 103) cut along a YZ plane passing through the slit 103A.

Here, the one-end roller mechanism 101 includes the one-end handling member 101A and the one-end shaft support member 101B. The upper surface portion C1 of C is disposed so as to be inclined from one end portion side to the other end portion side. Further, since the other end roller mechanism 102 includes the other end handling member 102A and the other end shaft support member 102B, the other end handling member 102A is separated from the upper surface C1 of the cover C. Accordingly, the cover C is disposed so as to be inclined from the other end side to the one end side in the upper surface C1 of the cover C. In other words, the one end handling member 101A and the other end handling member 102A are arranged to intersect each other.
In the present embodiment, the one end handling member 101A and the other end handling member 102A are disposed so as to intersect with each other, but may be disposed so as not to intersect.

FIG. 27 is a functional block diagram illustrating a schematic configuration of the cover handling device.
As shown in FIG. 27, the cover handling apparatus 10 includes the handling moving mechanism 104 described above and handling handling means 105 for controlling the handling mechanism 104.
The handling control unit 105 includes a CPU (Central Processing Unit), a memory, and the like, and executes information processing according to a predetermined program stored in the memory. The handling control unit 105 includes a handling control unit 1051.

  The handling control unit 1051 moves the roller head 103 with the handling moving mechanism 104 so that the one end roller mechanism 101 and the other end roller mechanism 102 simultaneously handle the upper surface portion C1 of the cover C.

FIG. 28 is a diagram illustrating a flowchart of cover handling processing executed by the cover handling device.
When the upper surface portion C1 of the cover C is handled by the cover handling device 10, the handling control means 105 executes steps ST101 to ST102 as shown in FIG. 28 according to a predetermined program stored in the memory. .
Details of steps ST101 to ST102 will be described below with reference to the drawings.

  First, the handling control means 105 detects whether or not the pallet P has been transported to a predetermined position (see FIG. 25) on the conveyor 2 (ST101: pallet detection step). If the handling control means 105 determines in step ST101 that the pallet P has been transported to a predetermined position, the handling control means 105 executes processing in and after step ST102. On the other hand, when it is determined in step ST101 that the pallet P has not been conveyed to a predetermined position, the handling control unit 105 performs the cover handling process without executing the processes after step ST102. finish.

  When it is determined in step ST101 that the pallet P has been transported to a predetermined position, the handling control unit 1051 moves the roller head 103 with the handling moving mechanism 104, thereby causing the one-end roller mechanism 101 and the like to move. The end roller mechanism 102 simultaneously handles the upper surface C1 of the cover C (ST102: cover handling step). Specifically, the handling control unit 1051 lowers the roller head 103 by the handling moving mechanism 104.

FIG. 29 is a diagram illustrating the cover handling device with the roller head lowered.
When the roller head 103 is lowered by the handling moving mechanism 104, the rod-shaped member 101A1 rotates about the one end support member 101B as shown in FIG. 29, and the roller 101A2 is moved from the center of the cover C. The upper surface portion C1 of the cover C is handled toward one end portion.
Further, the rod-shaped member 102A1 rotates around the other-end shaft support member 102B, and the roller 102A2 handles the upper surface portion C1 of the cover C from the center portion of the cover C toward the other end portion.

  Thereafter, the handling control unit 105 controls the handling moving mechanism 104 to return to the initial state (the state shown in FIG. 26), and again executes the above-described step S101 for the next pallet P, thereby performing the step. Repeat ST101 to ST102.

According to the present embodiment as described above, the following operations and effects can be achieved.
(1) The container opening device 6 includes a hook disengagement machine 62 that disengages the hook part 204 of the container 20 and a hook disengagement machine 62 that disengages the hook part 204. A hinge rotating machine 63 that rotates the hinge portion 203 of the container 20 is provided. In other words, the container opening device 6 performs the disengagement of the hook portion 204 and the rotation of the hinge portion 203 by separate devices. Accordingly, the container opening device 6 employs the hook disengagement machine 62 having a structure in which the engagement of the hook portion 204 is easily released and the container 20 is not easily damaged. Therefore, the container 20 can be opened without damaging it, and the production efficiency of the compact as the final product can be improved.

(2) After the hook engagement releaser 62 is inserted into the engagement portion of the hook portion 204 by advancing the flat insertion member 621 with respect to the hook portion 204 by the release advance / retreat mechanism 622, Since the engagement of the hook portion 204 is released by rotating the fitting member 621 by the rotation mechanism 623, the configuration of the hook engagement release machine 62 can be simplified.
(3) Since the rotation mechanism 623 rotates the fitting member 621 without moving it in the direction opposite to the opening direction of the container 20, the engagement of the hook portion 204 is released without applying a load to the container 20. be able to. In other words, the rotation mechanism 623 can release the engagement of the hook portion 204 without damaging the container 20.

(4) The insertion member 621 extends on the rotation axis of the rotation mechanism 623 and has one side parallel to the advancing / retreating direction of the release advance / retreat mechanism 622. The rotation mechanism 623 includes the insertion member 621. Since the fitting insertion member 621 is rotated in a direction opposite to the opening direction of the container 20, the fitting insertion member 621 can be rotated. Therefore, the rotation mechanism 623 can release the engagement of the hook portion without applying a load to the container 20.

(5) The hinge rotating machine 63 is released from the hook engagement release machine 62 by the hook engagement release machine 62, and then the hook engagement release machine 62 uses the other end of the container body 201 and the other end of the lid member 202. Since the container 20 is opened by rotating the hinge portion 203 while the doors are separated from each other, the container 20 can be opened by interlocking the hook disengaging machine 62 and the hinge rotating machine 63. The manufacturing efficiency of the compact can be further improved.
(6) The hinge rotation machine 63 inserts the insertion member 631 between the container main body 201 and the lid member 202 by moving the insertion member 631 by the rotation moving mechanism 632, and the container main body 201 is inserted by the insertion member 631. Since the hinge part 203 is rotated by pushing out, the configuration of the hinge rotating machine 63 can be simplified.

(7) Since the hinge rotating machine 63 pushes out the container body 201 by the insertion member 631 and rotates the hinge portion 203, the container 20 can be completely opened without being obstructed by the insertion member 631.
(8) The hinge rotating machine 63 rotates the hinge portion 203 when the other end of the container main body 201 and the other end of the lid member 202 are separated by the hook engagement release machine 62, whereby the container 20 Since the other end of the container body 201 and the other end of the lid member 202 are separated by the hook disengagement machine 62, the container 20 that is closed again by its own weight is opened. Also, the insertion member 631 can be reliably inserted between the container body 201 and the lid member 202.

(9) The insertion member 631 is formed in a cylindrical shaft shape, and is inserted between the container body 201 and the lid member 202 so that the axis of the insertion member 631 and the rotation axis of the hinge portion 203 are parallel to each other. Therefore, the hinge part 203 can be rotated by bringing the peripheral surface into contact with the container body 201. Therefore, the hinge rotating machine 63 can rotate the hinge part 203 without damaging the container 20.

(10) Since the cover holding means 93 supports the one end holding means 931 and the other end holding means 932 so as to be able to advance and retreat with respect to the upper surface of the container 20, the cover controller 952 covers the cover C toward the upper surface of the container 20. When the cover C is caught by the end of the container 20 when it is lowered and covered, the one end holding means 931 and the other end holding means 932 are raised so as to be separated from the container 20. In other words, the cover holding means 93 can cover the cover C on the container 20 by raising and bending both ends of the cover C. Therefore, the cover coating apparatus 9 can efficiently cover the cover C on the container 20.

(11) Since the cover holding means 93 fixes and supports the cylindrical shaft body 933A that holds the central portion of the cover C, the cover control unit 952 lowers the cover C toward the upper surface of the container 20 and covers it. At this time, the cylindrical shaft body 933 </ b> A does not rise so as to be separated from the container 20. Accordingly, the cover covering device 9 can be easily bent by raising the end portion of the cover C, so that the cover C can be more efficiently covered with the container 20.
(12) Since the one-end holding means 931 and the other-end holding means 932 include the recesses 931A and 932A that receive the cover C when holding the cover C, the covering control unit 952 moves toward the upper surface of the container 20. When the cover C is lowered and covered, the movement of the cover C with respect to the one end holding means 931 and the other end holding means 932 can be restricted. Therefore, the cover coating apparatus 9 can cover the cover C on the container 20 more efficiently.

(13) Since the cover handling device 10 lowers the cover C toward the upper surface of the container 20 and covers the cover C, the cover handling device 10 handles the upper surface of the cover C. Therefore, by raising and bending the end of the cover C, The wrinkles attached to the cover C can be removed by handling the upper surface portion C1 of the cover C. Even if the cover C is caught on the end portion of the container 20, the cover C can be reliably covered with the container 20.
(14) The handling control unit 1051 handles the upper end portion C1 of the cover C from the center portion of the cover C toward one end portion and the one end roller mechanism 101 from the center portion of the cover C toward the other end portion. Since the roller mechanism 102 for the other end that handles the upper surface portion C1 of the cover C simultaneously handles the upper surface portion C1 of the cover C, wrinkles on the cover C can be efficiently removed.

(15) Since the one end handling member 101A and the other end handling member 102A are arranged so as to intersect, the cover handling apparatus 10 includes, for example, the one end handling member 101A and the other end handling member 102A. The load applied to the container 20 and the cover C can be reduced as compared with the case where the container 20 and the cover C are disposed so as not to intersect.
(16) Since the one end handling member 101A and the other end handling member 102A abut the side surfaces of the rollers 101A2 and 102A2 against the upper surface portion C1 of the cover C, the cover handling device 10 loads the container 20 and the cover C. Can be further reduced.

The frame 622A supports the shaft portion 624A of the fitting member 624 via the elastic member 622A1. Accordingly, the frame 622A supports the fitting member 624 in a swingable manner.

The rotation mechanism 623 is provided on the three pinions 623A concentrically fixed to each of the shaft portions 624A of the fitting member 624 and the frame 622A so as to be movable along the X-axis direction, and the pinion 623A. A rack 623B that meshes with the frame 622A, a linear actuator 623C that moves the rack 623B along the X-axis direction, and a support base 623D that supports the rack 623B. Therefore, the rotation mechanism 623 rotates the insertion member 624 about the axis parallel to the advance / retreat direction of the release advance / retreat mechanism 622 (around the Y axis) by moving the rack 623B by the linear actuator 623C.
Here, the frame 622A supports the fitting member 624 in a swingable manner, but the pinion 623A meshes with a rack 623B provided on the frame 622A, and therefore the fitting member 624 has a −Z axial direction. Movement to the side is regulated.

FIG. 33 is a diagram illustrating a flowchart of hook release processing executed in the container opening device.
When the container opening device 6A opens the container 20, the opening control means 64A executes steps ST611 to ST615 as shown in FIG. 33 in accordance with a predetermined program stored in the memory.
Hereinafter, details of steps ST611 to ST615 will be described with reference to the drawings.

FIG. 34 is a top view of the container opening device showing a state where the nozzle is advanced with respect to the pallet.
First, the lid opening control means 64A detects whether or not the pallet P has been conveyed to a predetermined position (see FIG. 31) on the conveyor 2 (ST611: pallet detection step). When it is determined in step ST611 that the pallet P has been transported to a predetermined position, the lid opening control means 64A executes the processing after step ST612. On the other hand, when it is determined in step ST611 that the pallet P has not been transported to the predetermined position, the lid opening control means 64A performs the hook release processing without executing the processing in step ST612 and subsequent steps. Exit.

  If it is determined in step ST611 that the pallet P has been conveyed to a predetermined position, the suction control unit 641 advances the frame 612A to the pallet P by the linear actuator 612B as shown in FIG. Thus, the nozzle 611 is inserted into the communication hole P3 of the pallet P (see the thick arrow in the figure). The suction control unit 641 sucks the container 20 placed on the pallet P through the communication hole P3 of the pallet P with a suction device (not shown) connected to the nozzle 611, thereby causing the container 20 to move to the pallet. It fixes to P (ST612: container suction step).

FIG. 35 is a top view of the container opening device showing a state in which the regulating means is advanced with respect to the pallet.
Next, as shown in FIG. 35, the restriction control unit 645 advances the contact member 625A relative to the pallet P by causing the linear actuator 625C to advance the frame 625B (see thick arrows in the figure). As a result, the restricting means 625 contacts the end of the container 20 on the hinge part 203 side, and restricts the movement of the container 20 toward the hinge part 203 (ST613: container restricting step).

FIG. 36 is a top view of the container opening device showing a state in which the fitting member is advanced with respect to the hook portion of the container.
Next, as shown in FIG. 36, the insertion control unit 642 moves the frame 622A relative to the container 20 with the linear actuator 622B (see the thick arrow in the figure), so that The knife portion 624B of the insertion member 624 is inserted (ST614: knife insertion step).

FIG. 37 is a top view of the container opening device showing a state in which the engagement member is rotated to release the engagement of the hook portion of the container.
Next, as shown in FIG. 37, the release control unit 643 moves the rack 623B to the + X-axis direction side by the linear actuator 623C (see the thick arrow in the figure), thereby moving the fitting member 624 around the Y-axis. Rotate. Then, the release control unit 643 releases the engagement of the hook unit 204 with the knife unit 624B by rotating the insertion member 624 (ST615: hook release step).

FIG. 38 is a side view and a cross-sectional view of the container opening device showing a state in which the engagement of the hook portion of the container is released. Specifically, FIG. 38 is a view (left view) of the main part of the container opening device 6A viewed from the + Y-axis direction side, and a cross-sectional view taken along the line AA in the left view (right view). FIG. 38A is a diagram showing a state before the insertion member 624 is rotated, and FIG. 38B is a diagram showing a state in the middle of the rotation of the insertion member 624. is there.
Here, in the container suction step ST612 described above, the suction control unit 641 uses the suction device (not shown) connected to the nozzle 611 for the container 20 placed on the palette P, as shown in FIG. The container 20 is fixed to the pallet P by suction through the communication hole P3 (see the thin arrow in the figure).

In the knife insertion step ST614 described above, the insertion control unit 642 moves the frame 622A with respect to the container 20 with the linear actuator 622B as shown in FIG. The knife portion 624B of the insertion member 624 is inserted into the engagement site.
In the hook release step ST615 described above, the release control unit 643 releases the engagement of the hook unit 204 with the knife unit 624B by rotating the fitting member 624 as shown in FIG. To do.

At this time, as described above, the frame 622A supports the fitting member 624 in a swingable manner, so that the fitting member 624 advances in the opening direction (+ Z axis direction) of the container 20 ( (See thick arrow in the figure). Thus, the rotation mechanism 623 advances the insertion member 624 with respect to the opening direction of the container 20 when rotating the insertion member 624. In other words, the rotation mechanism 623 rotates the fitting member 624 without moving it in the direction opposite to the opening direction of the container 20 (−Z axis direction).
In this embodiment, the rotation mechanism 623 rotates the fitting member 624 without moving the fitting member 624 in the direction opposite to the opening direction of the container 20, but the fitting member 624 opens the container 20 in the opening direction. You may rotate so that it may move in the opposite direction. In this case, it is preferable to employ an insertion member made of a material that does not easily damage the container.

Thereafter, the release control unit 643 rotates the insertion member 624 about the Y axis by moving the rack 623B to the −X axis direction side by the linear actuator 623C. And the cancellation | release control part 643 returns the knife part 624B of the insertion member 624 to the state before rotation by rotating the insertion member 624. FIG.
Further, the insertion control unit 642 retracts the knife portion 624B of the insertion member 624 by retracting the frame 622A with respect to the container 20 by the linear actuator 622B.
Further, the restriction control unit 645 retracts the contact member 625A with respect to the pallet P by retracting the frame 625B with the linear actuator 625C.

  Thereafter, the lid opening control means 64A controls the container suction device 61 to return to the initial state (the state shown in FIG. 31), and again executes the above-described step ST611 for the next pallet P, thereby performing the step. ST611 to ST615 are repeatedly executed.

FIG. 39 is a diagram illustrating a flowchart of hinge rotation processing executed in the container opening device.
When the container opening device 6A opens the container 20, the opening control means 64A executes steps ST621 to ST625 as shown in FIG. 39 according to a predetermined program stored in the memory.
Hereinafter, details of steps ST621 to ST625 will be described with reference to the drawings.

  First, the lid opening control means 64A detects whether or not the pallet P has been conveyed to a predetermined position (see FIG. 30) on the conveyor 2 (ST621: pallet detection step). When it is determined in step ST621 that the pallet P has been transported to a predetermined position, the lid opening control means 64A performs the processing after step ST622. On the other hand, when it is determined in step ST621 that the pallet P has not been transported to the predetermined position, the lid opening control means 64A performs the hinge rotation without executing the processing after step ST622. The process ends.

  If it is determined in step ST621 that the pallet P has been conveyed to a predetermined position, the suction control unit 641 moves the frame 612A relative to the pallet P by the linear actuator 612B, thereby moving the nozzle 611 to the pallet P. Is inserted into the communication hole P3. The suction control unit 641 sucks the container 20 placed on the pallet P through the communication hole P3 of the pallet P with a suction device (not shown) connected to the nozzle 611, thereby causing the container 20 to move to the pallet. It fixes to P (ST622: container suction step).

  FIG. 40 is a side view of the hinge rotating machine showing a state in which the hinge portion of the container is being rotated. Specifically, FIG. 40 is a view of the hinge rotating machine 63A viewed from the −X axis direction side. 40A is a view showing a state in which the container main body 201 is held by the vacuum pad 633. FIG. 40B is a view in which the hinge part 203 of the container 20 is rotated by the vacuum pad 633. 40C is a diagram showing a state in which the insertion member 631A is in contact with the container body 201, and FIG. 40D is a hinge of the container 20 at the insertion member 631A. It is a figure which shows the state which is rotating the part.

  Next, as shown in FIG. 40A, the holding control unit 646 moves the support member 634 by the rotation moving mechanism 632 to bring the vacuum pad 633 close to the container main body 201. Then, the holding control unit 646 causes the vacuum pad 633 to suck the container main body 201 and thereby causes the vacuum pad 633 to hold the container main body 201 (ST623: container holding step).

Thereafter, the first rotation control unit 647 pulls out the container body 201 with the vacuum pad 633 by moving the support member 634 with the rotation moving mechanism 632 as indicated by a thin arrow in FIG. Then, the hinge part 203 is rotated (ST624: first rotation step).
At this time, the first rotation control unit 647 rotates the vacuum pad 633 around the central axis of the shaft portion 632A according to the position of the container body 201 by rotating the shaft portion 632A with the motor 632C. Yes.

  Next, as shown in FIG. 40C, the second rotation control unit 648 rotates the hinge unit 203 by the first rotation control unit 647 and then rotates the shaft unit 632A by the motor 632C. By moving it, the insertion member 631A is brought into contact with the container body 201 (see thin arrows in the figure).

Then, as shown by a thin arrow in FIG. 40D, the second rotation control unit 648 pushes the container body 201 with the insertion member 631A to rotate the hinge unit 203 (ST625: second rotation step). ).
At this time, the second rotation control unit 648 rotates the shaft portion 632A by the motor 632C to rotate the insertion member 631A around the central axis of the shaft portion 632A according to the position of the container body 201. Yes.

  In the present embodiment, the second rotation control unit 648 pushes the container body 201 by the insertion member 631A to rotate the hinge unit 203, but pushes the lid member by the insertion member to move the hinge unit. It may be rotated. In short, the second rotation control unit may push the container body or the lid member with the insertion member and rotate the hinge unit.

  In the present embodiment, the hinge rotating machine 63A includes the first rotation control unit 647 and the second rotation control unit 648, and the container body 201 is pulled out by the vacuum pad 633 to rotate the hinge unit 203. Then, the container main body 201 was pushed out by the insertion member 631A, and the hinge part 203 was rotated. On the other hand, the hinge rotating machine 63A includes only the first rotation control unit 647 and opens the container 20 only by pulling out the container body 201 with the vacuum pad 633 and rotating the hinge unit 203. May be.

  Thereafter, the lid opening control means 64A returns to the initial state by controlling the hinge rotating machine 63A, and repeats the above-described step ST621 for the next pallet P, thereby repeatedly executing steps ST621 to ST625. To do.

According to such this embodiment, the same operations and effects as (1) to (3), (6), (7), and (9) to (16) in the first embodiment can be achieved. In addition, the following actions and effects can be achieved.
(17) When the rotation mechanism 623 rotates the insertion member 624, the rotation member 624 advances the insertion member 624 with respect to the opening direction of the container 20. It can be rotated without moving in the opposite direction. Therefore, the rotation mechanism 623 can release the engagement of the hook portion 204 without applying a load to the container 20.

(18) Since the hook engagement releaser 62A is provided with the restricting means 625 for restricting the movement of the container 20 toward the hinge part 203, the flat fitting insertion member 624 is hooked by the release advance / retreat mechanism 622. By advancing with respect to 204, the movement of the container 20 toward the hinge part 203 side can be restricted when the hook part 204 is inserted into the engaging part. Therefore, since the hook disengaging machine 62A can disengage the hook portion 204 without changing the position of the container 20, the subsequent apparatus (for example, the cover covering apparatus 9) can perform the process efficiently. This can be implemented, and the production efficiency of the compact as the final product can be improved.

(19) The hinge rotating machine 63A holds the container main body 201 on the vacuum pad 633, and then moves the vacuum pad 633 with the moving mechanism 632 for rotation to pull out the container main body 201 with the vacuum pad 633 and hinge it. Since the part 203 is rotated, the configuration of the hinge rotating machine 63A can be simplified.
(20) Since the vacuum pad 633 sucks and holds the container main body 201, the hinge rotating machine 63A can rotate the hinge part 203 without damaging the container 20.

(21) The hinge rotating machine 63A holds the container body 201 on the vacuum pad 633, and then moves the support member 634 by the rotation moving mechanism 632, thereby pulling out the container body 201 by the vacuum pad 633 and hinges. The part 203 can be rotated. Then, the hinge rotating machine 63A pulls out the container body 201 with the vacuum pad 633 and rotates the hinge portion 203, and then moves the support member 634 with the rotation moving mechanism 632, thereby moving the insertion member 631A into the container. The hinge part 203 can be rotated by inserting between the main body 201 and the lid member 202 and pushing out the container main body 201 with the insertion member 631A. That is, the hinge rotating machine 63A forms a gap sufficient to pull out the container main body 201 by the vacuum pad 633 and insert the insertion member 631A between the container main body 201 and the lid member 202, and the insertion member 631A is inserted in this gap. , The container body 201 is pushed out by the insertion member 631A, and the hinge part 203 can be rotated. Therefore, the hinge rotating machine 63A can rotate the hinge portion 203 without damaging the container 20.
