Then, the support member 6 on the left side in the cart width direction is moved in the vertical direction. That is, the driven chain 71 moves the support member 6 on the left side in the cart width direction upward by moving the piston rod 103 upward. On the other hand, the driven chain 71 moves the support member 6 on the left side in the cart width direction upward by moving the piston rod 103 downward.

  The lock mechanism 8 has a lock position (predetermined position; FIG. 5B and FIG. 5C) in which the push-up bar 50 is provided at a position above the lower end position when each container setting unit 4 is moved to the retracted position. )), Each container set unit 4 is held in the retracted position.

  Specifically, the lock mechanism 8 includes a lock plate 80, a tension spring 81, and a notch 82. The lock plate 80 is provided for each container set portion 4 (for each frame-shaped frame portion 11). Each lock plate 80 is provided between the upper and lower bar support bases 52 and 53 of each frame-shaped frame portion 11. Each lock plate 80 is movable in the cart length direction. Each lock plate 80 is formed in a substantially rectangular shape. Each lock plate 80 is formed with an insertion hole 80a. The insertion hole 80a is formed in a substantially rectangular shape. The vertical bar 50b of the push-up bar 50 is inserted through the insertion hole 80a.

  The tension spring 81 is provided for each lock plate 80. One end of each tension spring 81 is connected to the end of each lock plate 80 on the front side in the cart length direction. The other end of each tension spring 81 is connected to a support base 83 for spring provided on the outer surface in the carriage width direction at the front side in the carriage length direction of the upper frame part 11a of each frame-like frame part 11. ing. Each tension spring 81 urges each lock plate 80 forward in the cart length direction.

  The notch 82 is provided for each vertical bar 50 b of the push-up bar 50. Each notch 82 is formed in the rear portion of each vertical bar 50b in the cart length direction. Each notch 82 is moved in the upward direction of the push-up bar 50, so that each lock plate 80 is pulled forward in the length direction of the cart by the urging force of each tension spring 81, so that the cart length in the insertion hole 80 a of each lock plate 80 is increased. Engage with the rear part in the vertical direction. By this engagement, the push-up bar 50 is held at the lock position.

  The one-way lock release mechanism 9 releases the holding of each container setting unit 4 in the retracted position by releasing the holding of the push-up bar 50 in the locked position. The one-way lock release mechanism 9 places the containers C stacked in two rows and five stages on the carriage V set in the carriage set portion 2, and then moves the second moving mechanism 7 from the lower end position to the upper end position of the support member 6. During the movement, the holding of the push-up bar 50 in the locked position is released by interlocking with the downward movement of the piston rod 103 (the operation of the air cylinder 100).

  Specifically, the one-way lock release mechanism 9 includes a release lever 90 and a release wire 91. The release lever 90 is a rotation axis X3 extending in the cart width direction with respect to the lever support base 92 provided on the outer surface in the cart width direction of the rear frame portion 11d of the frame-like frame portion 11 on the right side in the cart width direction. It is supported so as to be rotatable around. The release lever 90 is in a horizontal state at normal times. The release lever 90 is a one-way type. That is, when the release lever 90 is moved downward, the lower surface of the plate-like member 103a provided at the tip of the piston rod 103 comes into contact with the tip of the release lever 90. Move. The release lever 90 automatically returns from its rotating state to the horizontal state by the urging force of an urging member (not shown) when the external force is lost. On the other hand, the release lever 90 will not be described in detail when the piston rod 103 is moved upward. However, the horizontal state is maintained as a whole.

  One end of the release wire 91 is connected to the tip of the release lever 90. The release wire 91 is divided into two forks on the way. Each end of the release wire 91 opposite to the release lever 90 is connected to the end of each lock plate 80 on the rear side in the cart length direction.

  The release lever 90 is held when the push-up bar 50 is held in the locked position by the lock mechanism 8 and when the piston rod 103 moves downward, the plate-like member 103a comes into contact therewith and rotates downward from the horizontal state. By doing so, the end of the release wire 91 on the release lever 90 side is pulled downward. By this pulling, each lock plate 80 connected to each end of the releasing wire 91 opposite to the releasing lever 90 is pulled to the rear side in the cart length direction. By this pulling, the engagement between the notch portion 82 of each vertical bar 50 b of the push-up bar 50 and the insertion hole 80 a of each lock plate 80 is released. By releasing the engagement, the push-up bar 50 automatically moves from the lock position to the lower end position due to its own weight.

The axial direction of the air cylinder 100 coincides with the vertical direction. The air cylinder 100 has a cylinder body 101, a piston 102, and a piston rod 103. The piston 102 is a plug-like member that can be reciprocated in the cylinder body 101. The piston rod 103 is a rod that is connected to the piston 102 and transmits the movement of the piston 102 to the outside of the cylinder body 101. The piston rod 103 faces downward.

  Hereinafter, the stacking operation process of the stacking apparatus A will be described.

  First, the carriage V is set at a predetermined position of the plate-like member 20 of the carriage setting unit 2.

  Next, (a) the two rows of containers C transported from the upstream transport path are received by the container setting unit 4, and the transport roller 41 is transported forward in the cart length direction so that a predetermined position of the container setting unit 4 Set to.

  (B) When it is detected by the container detection limit (not shown) that two rows of containers C are set in the container setting section 4, the piston rod 103 of the air cylinder 100 is moved upward and moved upward, The second moving mechanism 7 moves the support member 6 downward from the upper end position to the lower end position.

  Then, (c) the piston rod 103 is moved downward and the support member 6 is moved upward by the second moving mechanism 7, so that the container setting unit 4 is positioned between the lower end position and the upper end position. The container C set in the container setting portion 4 is supported by the support member 6 at a support position (see FIG. 5A) for supporting the container C set in the container.

  Thereafter, (d) the piston rod 103 is moved downward to move the support member 6 supporting the container C up to the upper end position by the second moving mechanism 7.

  As described above, by repeating the operation steps (a) to (d) five times, the support member 6 supporting the containers C stacked in two rows and five stages is moved to the upper end position. In the second and subsequent times (b), the container C supported by the support member 6 is placed on the container C set in the container setting unit 4. In (c) after the second time, the lowermost container C is supported by the support member 6.

  When the support member 6 is moved to the upper end position, the uppermost container C comes into contact with the horizontal bar 50a of the push-up bar 50, so that the push-up bar 50 moves upward. By the upward movement of the push-up bar 50, the moving wire 55 is pulled toward the push-up bar 50. By this pulling, each container setting unit 4 rotates upward and outward in the cart width direction, and moves from the set position to the retracted position.

  When each container set unit 4 is moved to the retracted position, the contact member of the promotion wire guiding 56a on the left side in the cart width direction is rotated by the rotation of the promotion wire guiding 56a accompanying the rotation of the container set unit 4. It abuts on the left end of the slide spacer 30 in the cart width direction and pushes the slide spacer 30 to the right in the cart width direction. By this pressing, the slide spacer 30 is positioned between the end of the plate-like member 20 on the rear side in the cart length direction and the lower lateral plate portion 31 c of the lifting member 31.

  When the push-up bar 50 is moved upward, the lock plate 80 is pulled forward in the cart length direction by the urging force of the tension spring 81, whereby the notch 82 of the push-up bar 50 and the insertion hole 80a of the lock plate 80 are engaged. Match. By this engagement, the push-up bar 50 is held at the lock position.

  Next, when it is detected by a cart detection limit (not shown) that the cart V is set in the cart setting unit 2, the piston rod 103 is moved upward, and the second moving mechanism 7 makes two rows 5 The support member 6 supporting the stacked containers C is moved downward from the upper end position to the lower end position, and the container C supported by the support member 6 is placed on the carriage V at a position between the lower end position and the support position. In the loading position, the containers C stacked in two rows and five stages from the support member 6 are placed on the carriage V set on the plate-like member 20. At this time, since each container setting unit 4 is moved to the retracted position, each container setting unit 4 does not interfere with placing the container C on the carriage V.

  When the piston rod 103 moves upward, the upper surface of the plate member 103a provided at the tip of the piston rod 103 contacts the lower surface of the upper horizontal plate portion 31b of the lifting member 31, and the plate member 103a is in contact with the upper horizontal plate. By lifting the portion 31b, the lifting member 31 moves upward from the normal position. By the upward movement of the lifting member 31, the upper surface of the lower lateral plate portion 31c abuts the lower surface of the rear end portion of the plate-like member 20 in the carriage length direction via the slide spacer 30, and lifts the end portion. . By lifting the plate member 20, the plate member 20 is changed from a horizontal state to an inclined state. By changing the plate-like member 20 to the inclined state, the carriage V on which the containers C stacked in two rows and five stages are loaded automatically from the apparatus A to the front side in the carriage length direction (paid out).

  When it is detected by a feed detection limit (not shown) that the carriage V is fed out of the device A, the piston rod 103 is moved downward, and the second moving mechanism 7 moves the support member 6 to the lower end. Move upward from the position to the top position.

  The lower movement of the piston rod 103 causes the lower surface of the plate-like member 103a provided at the tip of the piston rod 103 to come into contact with the release lever 90, and the release lever 90 rotates downward to release it. The end of the wire 91 on the release lever 90 side is pulled downward. By this pulling, each lock plate 80 connected to each end of the releasing wire 91 opposite to the releasing lever 90 is pulled rearward in the length direction. By this pulling, the engagement between the notch portion 82 of the push-up bar 50 and the insertion hole 80a of the lock plate 80 is released. With this release, the push-up bar 50 is automatically moved from the lock position to the lower end position by its own weight.

  By the downward movement of the push-up bar 50, the movement wire 55 is released from being pulled toward the push-up bar 50. As a result of this release, the container setting portion 4 is rotated downward and inward in the cart width direction, and moved from the retracted position to the set position.

  As described above, the stacking operation process of the stacking apparatus A is completed.

-Effect-
As described above, according to the present embodiment, the containers C stacked in two rows and five stages are moved by the second moving mechanism 7 after the container moving portions 4 are moved from the set position to the retracted position by the first moving mechanism 5. In order to move the supported support member 6 to the lower end position and place the containers C stacked in two rows and five stages on the cart V set on the cart set unit 2, the container set unit 4 is placed at the receiving position as in the conventional case. It is not necessary to move between the stacking positions. Therefore, the stacking apparatus A can be reduced in size.

  Further, the first moving mechanism 5 moves each container set unit 4 to the retracted position by rotating each container set unit 4 upward and at the outside in the cart width direction at the set position. The stacking apparatus A can be reduced in size.

  Further, the first moving mechanism 5 has a push-up bar 50 that moves upward when the uppermost container C abuts when the support member 6 that supports the containers C stacked in two rows and five stages moves to the upper end position. And an interlocking mechanism 51 that moves each container setting unit 4 from the set position to the retracted position by interlocking with the upward movement of the push-up bar 50, so that two rows 5 supported by the support member 6 are provided. Using the stepped container C, each container setting unit 4 can be moved from the set position to the retracted position with a simple structure.

  In addition, when each container set unit 4 is moved to the retracted position, each container set unit 4 is held at the retracted position by holding the push-up bar 50 at the lock position provided above the lower end position. Since the locking mechanism 8 is provided, each container setting unit 4 can be reliably held at the retracted position.

  Further, a one-way lock release mechanism 9 is provided for releasing the holding of each container setting unit 4 in the retracted position by releasing the holding of the push-up bar 50 in the lock position. When the lock is released from the lock position, the container moves from the lock position to the lower side, and the interlocking mechanism 51 moves each container setting unit 4 from the retracted position to the set position by interlocking with the downward movement of the push-up bar 50. Therefore, it is possible to reliably release the holding of each container setting unit 4 to the retracted position and move each container setting unit 4 from the retracting position to the set position.

  In addition, an air cylinder 100 for driving the second moving mechanism 7 is provided, and the one-way unlock mechanism 9 places the containers C stacked in two rows and five stages on the cart V set in the cart set unit 2. When the second moving mechanism 7 moves upward from the lower end position of the support member 6, the second moving mechanism 7 is released in order to release the holding of the push-up bar 50 in the locked position by interlocking with the operation of the air cylinder 100. The push-up bar 50 can be released from being held in the locked position by using the air cylinder 100 that drives. Therefore, the driving means for driving the one-way lock release mechanism 9 is not necessary.

  Further, the carriage set unit 2 has a plate-like member 20 on which the carriage V is placed, and the plate-like member 20 is placed between a horizontal state and an inclined state inclined downward toward the front side of the carriage length direction. The change mechanism 3 to be changed is provided, and after the containers C stacked in two rows and five stages are placed on the carriage V set in the carriage set portion 2, the plate mechanism 20 is inclined from the horizontal state by the change mechanism 3. Therefore, the cart V on which the containers C stacked in two rows and five stages can be automatically sent from the device A to the front side in the cart length direction by its own weight.

  Further, the changing mechanism 3 is interlocked with the operation of the air cylinder 100 when the second moving mechanism 7 moves to the lower end position of the support member 6 that supports the containers C stacked in two rows and five stages. In order to change the plate-like member 20 from the horizontal state to the inclined state by moving the rear end of the bogie length direction to the upper side, the air cylinder 100 that drives the second moving mechanism 7 is used to change the plate. The shaped member 20 can be changed from the horizontal state to the inclined state. Therefore, the drive means for driving the change mechanism 3 is not necessary.
