Description

  The present invention relates to an elevator parking apparatus of a lower entry system that turns a pallet to a predetermined angle when entering and leaving.

  Conventionally, an elevator type parking apparatus is an elevator of a lower entry type that is stored after the pallet is lifted and turned 90 ° by a pallet lifting and turning device installed in a pit of a lower entry part according to installation conditions and the like. A parking system is used.

  For example, there is an elevator parking device described in Patent Document 1 as such an elevator parking device. In this elevator type parking device, a table (hereinafter referred to as a “swivel platform”) of a turn device with a lifter (hereinafter referred to as a “pallet lifting and turning device”) is provided in the vertical direction at the center of a carriage (hereinafter referred to as an “elevator carrier”). The front and rear parts of the elevator car are provided with telescopic fork devices for transferring pallets in the lateral direction between the elevator car and the parking rack. A step for the user to walk (hereinafter referred to as “elevator deck”) is provided.

  However, in the case of the above elevator type parking device, in order to avoid interference between the telescopic fork device and the elevator deck during pallet transfer, the elevator deck is positioned at a lower position than the telescopic fork device, that is, the home position (hereinafter referred to as “entry”). It is arranged at a position considerably lower than the floor surface).

  Also, since the telescopic fork device is disposed at the longitudinal end of the elevator deck, it is impossible to provide a step at this portion, and the width (walking width) of the elevator deck is necessarily narrow. It has become.

  Therefore, when the user gets on and off the vehicle on the pallet, the step with the elevator deck is large, which hinders getting on and off, and in addition to the narrow width of the elevator deck, the step with the entrance floor is also large. It is difficult to walk in and out of the person.

  On the other hand, as a mechanism for transferring a pallet, there is a pallet transfer device that employs a twin crank arm system that is simpler than the telescopic fork device (see, for example, Patent Document 2). In this pallet transfer device, a swing arm having a locking roller attached to the tip thereof is installed on the front and rear parts of a lifting platform (elevator transporter) so as to be capable of reciprocating rotation. Is engaged with a transfer engaging groove provided at the lower end of the pallet side, and the pallet is transferred between the parking shelf and the lifting platform.

  For this reason, the pallet transfer device (twin crank arm method) described in Patent Document 2 is adopted in the elevator parking device of the 90 ° lower entry method described in Patent Document 1, and the front and rear parts of the elevator transporter are employed. It is conceivable to provide a walking deck over a wide area. In this case, as shown in FIG. 8, the elevator transporter 100 is provided with an opening 102 through which the swivel base 101 can pass in the vertical direction at the center, and a base is supported at the front and rear of the opening 102 so as to be horizontally rotatable. A crank arm 103 is provided. The crank arm 103 has a pallet transfer mechanism 105 of a twin crank arm type having an engagement roller 104 attached to the tip and having two crank arms 103. With such a configuration, the inner elevator deck 106 and the outer elevator deck 107 are provided at the front and rear portions of the opening 102, and the engaging roller 104 of the crank arm 103 is projected from between the decks 106, 107. It can be made to turn.

Japanese Patent No. 2717419 JP-A-9-209600

  However, in the case of the elevator transporter 100 configured as shown in FIG. 8, the inner elevator deck 106 that covers the crank arm 103 can be provided at a height position that matches the entry floor surface 108 at the time of loading and unloading. In order to avoid the turning trajectory of the engaging roller 104 during the turning operation of the arm 103 and provide the inner elevator deck 106, the deck width in the longitudinal direction of the elevator transporter 100 must be narrowed.

  Further, although the outer elevator deck 107 can be provided at the front and rear end portions of the elevator transporter 100, in order to allow the crank arm 103 to turn, it is installed at a position below the crank arm 103. A large step is formed between the inner elevator deck 106 and the inner elevator deck 106 positioned above the position 103. Therefore, when the user opens and closes the door of the vehicle V, the user is forced to take an unstable posture such as hanging one foot on the inner elevator deck 106 and the other foot on the stepped outer elevator deck 107. Moreover, getting on and off by wheelchair users is impossible.

  Furthermore, since the large step 112 is generated between the outer elevator deck 107 and the surrounding loading section fixing deck 111 in a state where the elevator transporter 100 is disposed in the loading section 110, the boarding / alighting is disturbed between these.

  In addition, the engagement roller 104 of the crank arm 103 is exposed in the frame of the elevator transporter 100, that is, above the outer elevator deck 107, in order to avoid interference with the fixed deck 111 of the loading portion 110, This also interferes with walking on the elevator deck 107.

  Accordingly, the present invention provides an elevator type parking apparatus that turns a pallet at the time of entering / exiting, and a lower entry system in which the entire entrance part surrounding the pallet at the time of entry / exit can form a substantially flat floor surface (deck surface). It is an object of the present invention to provide an elevator parking device.

  In order to achieve the above object, the present invention provides an elevator transporter that moves up and down a hoistway to store a pallet in a parking shelf, and an angle at which the pallet is stored in the parking shelf at the time of loading / unloading in a pit of a loading section. An elevator type parking apparatus having a pallet lifting and turning device for turning the pallet, wherein the elevator carrier has an opening in a central portion through which a turning table of the pallet lifting and turning device passes, and in front of the opening A pallet transfer mechanism having a crank arm that is supported so as to be horizontally rotatable at the rear and transfers the pallet between the elevator transporter and the parking rack with an engagement roller at the tip, and the crank arm of the pallet transfer mechanism And an elevator deck supported so as to be movable up and down from a position below the turning locus. The pallet lifting and turning device has the swivel platform more than the loading floor surface at the time of loading and unloading, having a deck notch formed from the center portion toward the left and right outer corners so as to pass in the direction. It is configured to wait at an upper turning level. In the specification and claims, the center direction of the elevator car is called “inside”, the end direction is called “outside”, the long direction is called “front-rear direction”, and the short direction is called “width direction”. As a result, the swivel that swivels the pallet at the entry section supports and turns the pallet at the upper swivel level that has passed through the opening of the elevator car, and the pallet is aligned with the entry floor (entry level). In this state, the crank arm is positioned in a deck notch formed toward the left and right outer corners of the elevator deck, and the elevator deck and the crank arm upper surface are placed on the same floor and the pallet is surrounded. The entire entry portion can be a substantially flat floor surface without a step.

  The crank arm may have a flat upper surface, and the deck notch may be formed with a width dimension having a predetermined narrow gap with the crank arm. In this way, the top surface of the elevator deck is almost flat with only a narrow gap between the elevator deck and the crank arm by making the top surface of the crank arm flush with the top surface of the elevator deck at the deck notch position. It can be formed on any deck surface.

  Furthermore, the said crank arm may be provided in the upper end part surrounding surface of the turning cylinder arrange | positioned in the width direction center position of the said elevator transporter. If it does in this way, the upper surface can be made into a substantially flat surface, suppressing the height of the composition which protrudes upwards from an elevator deck and turns a pallet.

  The crank arm may have a flat upper surface that is rectangular in plan view, and the deck notch may be formed in a rectangular shape having a predetermined narrow gap from the upper surface of the rectangular crank arm. In this way, the shape of the deck notch can be simplified, and the gap with the crank arm can be further narrowed.

  Furthermore, the deck notch may be formed toward an outer corner on one side of the loading portion in the direction of the entrance / exit. If it does in this way, the user who entered from the entrance / exit can also get on and off without passing through the deck notch, and the wheelchair user can also get on and off more stably.

  In addition, the elevator deck may have a lifting guide portion supported in a vertically movable manner at a lower portion and a landing portion supported on the same level as the entry floor surface at a side edge portion. In this way, by supporting the landing part of the elevator deck at the same level as the entry floor surface, the elevator deck can be supported flush with the entry floor surface without requiring power.

  According to the present invention, since the entire entry portion of the swing-type lower entry type elevator parking apparatus can be formed on a substantially flat floor surface, the user can easily get on and off and walk. Further, by forming a barrier-free entry section, a wheelchair user can also easily use it.

The pallet 20 is lifted up to 80 and turned. This lifted turning level 80 is also a level at which the turntable 27 is put on standby.

  As shown in FIG. 3B, the pallet placement traverse support mechanism 55 is provided at the front and rear of the elevator car 13 and at the front and rear of the parking rack 11 as described above. The pallet placement traverse support mechanism 55 is provided with a pallet placement traverse support roller 56 and a side regulating roller 57 for guiding the placement lateral member 22 provided on the lower surface of the pallet 20. The pallet 20 is transferred between the elevator transporter 13 and the parking rack 11 while being guided by the rollers 56 and 57.

  Based on FIG. 4A-FIG. 4D, the effect | action at the time of warehousing in the said elevator type parking apparatus 1 is demonstrated below.

  As shown in FIG. 4A, in a predetermined parking shelf 11, the elevator transporter 13 transfers the empty pallet 20 from the parking shelf 11 onto the elevator transporter 13 by turning inward of the crank arm 40, and then toward the entry unit 3. And descend. The empty pallet 20 is transferred by driving the drive motor 72 of the arm turning mechanism 45 so that the drive gear 71 rotates the driven gear 70 and is turned integrally with the turning cylinder 43. The engagement roller 41 is engaged with the groove member 21 of the pallet 20, and the pallet 20 is moved transversely while the engagement roller 41 moves along the groove member 21 by further inward turning of the crank arm 40.

  Next, as shown in FIG. 4B, the pallet 20 on the elevator transporter 13 reaches a turning level 80 above the entrance level 4 while the elevator transporter 13 reaches the entry part 3 and sinks into the pit 5. It is supported by the swivel 27 that is ascending and waiting, and is deposited. Then, when the elevator car 13 further descends, the engaging roller 41 of the crank arm 40 is released downward from the groove member 21 of the pallet 20. When the engaging roller 41 is completely detached from the groove member 21, the swivel base 27 is turned 90 °, and the pallet 20 is turned 90 °. Thereby, the longitudinal direction of the pallet 20 is directed to the entrance / exit 6 (FIG. 1) (a state of a two-dot chain line).

  Further, as shown in FIG. 4C, the crank arm 40 indicated by a two-dot chain line in a state where the engagement roller 41 is detached from the groove member 21 causes the elevator car 13 to temporarily stop the super deceleration state or the lowering in the final lowering stage. And is turned to the position of the deck cutout 50. The turning of the crank arm 40 is stopped when the crank arm 40 is aligned with the deck cutout 50 in a plan view. This operation is a retracting operation of the crank arm 40.

  Further, as shown in FIG. 4D, from the state shown in FIG. 4C, in the final descending stage of the elevator transporter 13, first, the landing members 34 of the elevator decks 32 and 33 are seated on the upper surface of the side fixed deck 17 (entry level 4). Next, when the upper surface of the revolving cylinder 43 and the upper surface of the crank arm 40 are aligned with the entry level 4 (the upper surfaces of the elevator decks 32 and 33), the lowering of the elevator car 13 is stopped.

  The elevator decks 32 and 33 during the operation are supported by the seating member 34 seated on the side fixed deck 17 because the guided rod 37 fixed to the lower surface is movable up and down within the guide cylinder 36. Even if the elevator transporter 13 is lowered after being moved, the guided rod 37 is guided by the guide cylinder 36 and slides, and the state where it is supported by the side fixed deck 17 is maintained. Further, the turning cylinder 43 and the crank arm 40 are fitted in the central opening 51 and the inclined opening 52 in a non-contact manner, and the deck cutout 50 is closed by the upper surface of the turning cylinder 43 and the upper surface of the crank arm 40. A state is reached (FIG. 4C).

  Thus, the upper surfaces of the elevator decks 32 and 33 are supported in a state where they are flush with the upper surface of the side fixed deck 17 provided at the same level as the entry level 4 (entrance floor surface 4). The upper surface of the swivel cylinder 43 and the upper surface of the crank arm 40 which are stopped when aligned with the upper surface of 33 are aligned at the same level as the entry level 4 and are flush with each other.

  Further, during the retraction operation of the crank arm 40 and the seating operation of the elevator decks 32 and 33, the lowering operation of the swivel base 27 of the pallet lifting and swiveling device 26 is performed and directed to the swivel base 27 and the entrance / exit 6. When the pallet 20 is integrally lowered and the road surface 23 of the pallet 20 is aligned with the entry floor surface 4 (entry level 4), the descent of the swivel base 27 is stopped (a state of a two-dot chain line).

  By performing the sequential operation as described above, as shown in FIGS. 5 and 6, the pallet vehicle road surface 23, the elevator decks 32 and 33, and the side fixed decks 17 surrounding them are all flush with the entry floor surface 4. The entire entry portion 3 can be made flat and spacious with no steps and is barrier-free. Therefore, the user of the wheelchair 81 can also move on the same deck 17, 32, 33 and easily get on and off the vehicle V. Further, the engaging roller 41 at the tip of the crank arm 40 protrudes upward at the outermost part of the deck cutout 50. However, since the protruding position is the outermost corner, there is no hindrance to getting on and off and passing.

  Thereafter, the entrance / exit door 7 opens, the vehicle V gets on the pallet 20 (indicated by a two-dot chain line in FIG. 5), the user gets off (FIG. 6) and leaves. Then, when the entrance door 7 is closed, the elevator carrier 13 on which the vehicle V is mounted on the pallet 20 is raised by the reverse sequential operation of FIGS. 4A to 4D, and the pallet 20 mounted on the vehicle on the original parking shelf 11. To complete a series of warehousing operations.

  As described above, according to the elevator parking apparatus 1, when entering and exiting, as shown in FIGS. 5 and 6, the entry floor surface 4, the side fixed deck 17, the elevator decks 32 and 33, and the turning cylinder 43 The upper end surface of the pallet, the upper surface of the crank arm 40, and the pallet vehicle road surface 23 are all substantially aligned with the entry level 4, and the entire entry portion 3 surrounding the pallet 20 is formed on a substantially flat and spacious barrier-free floor. Therefore, it is possible to stably get on and off the user and walk in the insertion section 3, and not only a general user but also a wheelchair user can easily use it.

  Moreover, in the said embodiment, although the inclined opening 52 of the deck notch 50 is formed so that it may extend toward the outer corner part by the side of the loading / unloading port 6, the one side outside on the opposite side to the loading / unloading port 6 is formed. If the deck notch 50 is formed so that the inclined opening 52 extends toward the corner, a user entering and exiting from the entrance / exit 6 can get on and off without going over the deck notch 50 and use a wheelchair. The person can also get on and off more stably.

  FIGS. 7A and 7B are diagrams showing another example of the pallet transfer mechanism. In the above embodiment, in order to keep the vertical height of the arm turning mechanism 45 low, Although the base is fixed to the peripheral surface of the upper end portion of the swivel cylinder 43, as shown in the figure, a rotary shaft 47 is fixedly erected at the center of the upper surface of the swivel cylinder 43, and Alternatively, the bottom surface of the base portion of the crank arm 48 may be fixed. In this case, the base portion of the crank arm 48 may be a simple rectangular shape, and the deck notch 53 provided in the elevator decks 32 and 33 is also open outward with a predetermined narrow gap c in accordance with the plan view shape of the crank arm 48. Can be formed in a rectangular shape. Therefore, in this example, the shape of the deck cutout 53 can be made a simple rectangular shape, and the gap c can be made narrower. Further, the normal height position of the elevator decks 32 and 33 in this example is the position of the rotary shaft 47, that is, between the lower surface of the crank arm 48 and the upper surface of the revolving cylinder 43. In this example, the rectangular crank arm 48 having the same width in plan view with a flat upper surface is used. However, if the crank arm 48 has a flat upper surface, it may be tapered in plan view. In addition, since the other configuration is the same as that of the above-described embodiment, the same reference numeral is given to the same configuration, and the description thereof is omitted.

  In this way, when the crank arm 48 is flush with the upper surface of the deck cutout 53 and aligned with the entry level 4, the upper surface of the crank arm 48 becomes a floor surface that closes the deck cutout 53 with a slight gap c. The upper surface of the crank arm 48 can be a flat stepping place when getting on and off, which is flush with the upper surfaces of the elevator decks 32 and 33.

  The pallet lifting and turning device 26 in the above embodiment is an example, and may be configured to lift and turn the pallet 20 in another form, and is not limited to the above embodiment. .

  In addition, the vertical guide mechanism 35 and the pallet placement traverse support mechanism 55 of the elevator decks 32 and 33 in the above embodiment are also examples, and may have the same function in other configurations. The form is not limited.

  Furthermore, the seating portion (flooring member 34) provided at the side edge portion for supporting the elevator decks 32 and 33 by the side fixed deck 17 is an example, and the end portions of the elevator decks 32 and 33 are bent. The upper side of the elevator decks 32 and 33 may be supported by the side fixed deck 17 as long as the upper surface of the elevator decks 32 and 33 can be supported flush with the upper surface of the side fixed deck 17. .

  The above-described embodiment shows an example, and various modifications can be made without departing from the gist of the present invention. The present invention is not limited to the above-described embodiment.

  The elevator type parking apparatus according to the present invention can be used for an entry type elevator type parking apparatus such as a 90 ° lower entry system that turns a pallet at an entry part.
