Description

  The present invention relates to a horizontal circulation parking apparatus configured to horizontally circulate a pallet in a rectangular circulation path in which a vertical transfer path and a horizontal transfer path are alternately connected, and to enter and exit a vehicle, and more particularly to a vertical transfer path. Is related to pallet transfer measures.

  In Patent Document 1, rectangular circulation paths are installed in two layers on the upper and lower sides of a parking space in a building, and a plurality of pallets are vertically formed in a state where empty spaces are formed at diagonal positions of the vertical transfer path constituting the circulation path. By the operation of the transfer device and the horizontal transfer device, the pallet is alternately fed in the vertical transfer direction and the horizontal transfer direction one by one in the horizontal direction and horizontally circulated, and the vehicle is delivered between the loading / unloading unit and the parking space by the lifting lift. A horizontal circulation parking apparatus configured to enter and exit is disclosed.

  In such a horizontal circulation type parking device, the parking space is mostly formed underground, and the underground excavation cost occupies a considerable weight of the installation work cost, so the height of the underground parking space is as low as possible. Is set. Further, in an underground parking space where space is limited, it is required in terms of parking efficiency to be configured so as to accommodate a vehicle of a vehicle type having a vehicle height as high as possible.

  In particular, in a horizontal circulation parking system where the circulation path is installed in multiple layers, the height space occupied by the vertical transfer apparatus in the vertical transfer path has a significant effect on the height of the underground parking space and the number of vehicles that can be accommodated (vehicle height). Effect.

  However, in general, as disclosed in Patent Documents 2 and 3, the vertical transfer device is configured such that an endless chain is wound around two sprockets that rotate around a horizontal axis in a vertical plane, and the endless chain is vertically Since the feed mechanism circulates in the plane, the vertical thickness of the vertical transfer device becomes very thick.

Therefore, the vertical transfer device of Patent Document 1 points out the above-mentioned problems of Patent Documents 2 and 3, and is configured to circulate an endless chain in a horizontal plane as a solution. Specifically, as shown in FIG. 9, an upper sprocket mechanism d in which an endless chain c is wound around two sprockets b rotating around a vertical axis a in a horizontal plane, and the upper sprocket mechanism d, A lower sprocket mechanism h in which an endless chain g is wound around two sprockets f rotating around a vertical axis e in a horizontal plane is arranged in parallel vertically, and two upper and lower endless chains c of the sprocket mechanisms d and h are arranged. , G is attached with a support arm j having a U-shaped hook i for vertical pallet transfer, and the sprocket mechanisms d, h are simultaneously circulated in the same plane in the same direction by driving one motor k. . In FIG. 9, l is an engaging member provided on the lower surface of the pallet (not shown) and engaged with the hook i.
Japanese Patent No. 3079432 (4th page, FIGS. 4 and 7) Japanese Examined Patent Publication No. 48-24874 (pages 2, 3 and 2) JP-A-53-109380 (2nd page, FIG. 2)

  However, since the upper sprocket mechanism d and the lower sprocket mechanism h are arranged side by side in the vertical transfer device of the above-mentioned Patent Document 1, the vertical thickness of the vertical transfer device is inevitably increased accordingly. The reduction effect is insufficient.

  Further, in order to stabilize the posture of the support arm j so as not to hinder the transfer during the vertical transfer, the vertical distance between the upper and lower endless chains c and g is considered in consideration of the high-speed vertical transfer operation including decelerating. It is necessary to ensure a fairly wide area, and there is a limit in reducing the vertical thickness of the vertical transfer device as a practical problem. For this reason, there is a limit to reducing the height of the underground parking space, and the underground excavation work cost cannot be reduced as expected.

  In addition, when a circulation path is installed in multiple layers in an underground parking space where space is limited, a large interlayer distance cannot be secured, so that a vehicle with a high vehicle height cannot be accommodated, resulting in a reduction in accommodation efficiency.

  The present invention has been made in view of this point, and an object of the present invention is to reduce the vertical thickness of the vertical transfer device so as not to hinder the vertical transfer.

  In order to achieve the above object, the present invention is characterized in that the vertical transfer of the pallet is stably performed by a single endless chain that circulates in a horizontal plane.

  Specifically, this invention provides a rectangular circulation path in which a vertical transfer path having a vertical transfer apparatus and a horizontal transfer path having a horizontal transfer apparatus are alternately connected in a parking space, and a plurality of pallets in the circulation path. In a state where an empty space is formed at the diagonal position of the vertical transfer path, the vertical transfer device and the horizontal transfer device are actuated to feed the pitch alternately in the vertical transfer direction and the horizontal transfer direction by one pallet and horizontally circulate. The following solution was taken for a horizontal circulation type parking apparatus that is configured to deliver and receive a vehicle by a lifting lift between the entry / exit section and the parking space.

That is, according to the first aspect of the present invention, the vertical transfer device includes two sprockets that are spaced apart in the vertical transfer direction and rotate about a vertical axis in a horizontal plane, and are wound around these sprockets in a horizontal plane. And an endless chain that circulates and an engaging member that is detachably engaged with an engaged member that is provided on the lower surface of the pallet, and the endless chain is point-symmetric with respect to the center of the circulating track. Two circulating moving bodies formed in a U-shaped cross section with a pair of horizontal plane portions that are connected in the vertical direction and spaced apart from each other, and a vertical plane portion that vertically connects one end of these horizontal plane portions , The endless chain has two parallel linear track portions arranged close to the outside of the circulation track and two arc track portions continuous at both ends of the linear track portions. Spaced horizontally from each other Only a pair of vertical wall portions extending in parallel, are formed in the vertical middle of the vertical wall portion in H-shaped steel made of a horizontal wall portion for connecting together, and movably supporting the both circulating member An endless track having an elliptical shape that guides along the circulation track of the endless chain, and the inner surfaces of the vertical wall portions of the endless track are arranged above and below the horizontal wall on both horizontal surfaces of each circulation moving body. A horizontal roller that rotates and rolls around a vertical axis in a horizontal plane on both sides to restrict horizontal movement of the circulating moving body, and a horizontal wall portion of the endless track is rotated around the horizontal axis in a vertical plane. And a vertical roller that rolls so as to be sandwiched from above and below and restricts the vertical movement of the circulating mobile body, and each of the circulating mobile bodies has an engagement member at one of the circular arc track portions of the endless track body. The pallet is connected to the pallet by engaging with the engaged member on the lower surface of the pallet. It is configured to vertically move along the linear track portion toward the other arc track portion and to reverse the other arc track portion so that the engaging member is detached from the engaged member and separated from the pallet. It is characterized by.

According to a second aspect of the present invention, in the first aspect of the present invention, each circulating moving body includes a main moving body connected to an endless chain, and the main moving body pivots toward the inner periphery of the endless track. The main moving body moves as a single unit with the sub moving body in the linear track portion of the endless track body, while the arc track portion moves as a whole. Then, it is comprised so that it may move apart from the said sub moving body .

  According to the first aspect of the invention, since the pallet is vertically transported by one endless chain that circulates in a horizontal plane, compared to the case of vertically transporting by two upper and lower endless chains as in Patent Document 1. The vertical thickness of the vertical transfer device can be greatly reduced. Therefore, the height of the underground parking space can be reduced, and the underground excavation work cost can be reduced.

  In addition, when installing a multi-layered circulation path in an underground parking space with limited space, the distance between the layers can be increased compared to a parking device that conventionally only accommodates ordinary vehicles. Higher vehicle types (mid-roof vehicles, semi-high roof vehicles, etc.) can also be accommodated, and the accommodation efficiency of the parking device can be greatly improved.

  In addition, in a state where the engaging member of the circulating moving body connected to the endless chain is engaged with the engaged member on the lower surface of the pallet, the circulating moving body is movably supported by the endless track body to circulate the endless chain. Since it is guided along the track, the circulating moving body does not wobble even during high-speed vertical transfer, and the pallet can be stably transferred vertically.

Further, the horizontal roller rolls on the inner surfaces of both vertical walls of the endless track so that the horizontal movement of the circulating moving body is restricted, and the vertical roller holds the horizontal wall of the endless track from above and below. Since the vertical movement of the circulation moving body is restricted by rolling the movement of the circulation movement body, the wobbling during the vertical movement of the circulation movement body can be surely eliminated, and the stable vertical movement of the pallet can be ensured.

According to the second aspect of the present invention, the main moving body constituting the circulating moving body moves while separating from the auxiliary moving body in the arcuate track portion of the endless track body. Even when the stability of the transfer is ensured, the circular movement can be performed without increasing the radius of curvature of the arcuate track portion more than necessary .
