Description

  The present invention relates to a front gate device in a mechanical parking device.

  The mechanical parking device stores a car that has been received. A pallet is located at the warehousing position in the parking device. On this pallet, the car rides from the outside of the parking device. This pallet is driven to move to another position in the parking device. At this time, another pallet on which the automobile is not loaded is driven to move to the warehousing position. Another car can enter the other pallet from outside the parking device.

  A front gate device is provided so that an automobile or a person does not enter from outside during operation of such a parking device. The front gate device is provided in the entry passage where the automobile travels from the outside of the parking device to the entry position in the parking device. In the state where the front gate device is opened, an automobile or a person can pass through the entry passage. When the front gate device is closed, a car or a person cannot pass through the entry passage. When the parking device is activated, i.e. when the pallet is driven, the front gate device is closed. This prevents an automobile or a person from entering the parking device from the outside of the parking device during operation of the parking device.

  Such a front gate device is described in Patent Document 1 below, for example. In Patent Document 1, the rectangular passage-shaped gate body is driven up and down to open and close the warehousing passage. Guide struts for guiding the raising and lowering of the gate body are provided on both the left and right sides of the gate body. The gate body is suspended by a wire rope. A driven pulley is provided at both left and right ends of the gate body. One end of the wire rope is fixed to the upper end of the guide post on one side in the left-right direction that guides the raising and lowering of the gate body. The wire rope extends downward from the upper end of the guide column and is hung on one of the driven pulleys, then extends horizontally, is hung on the other driven pulley, and then extends upward and is wound on the drum. . Thus, the gate body is suspended by the wire rope via the two driven pulleys. When the motor rotates the drum, the gate body moves up and down between a position where the warehousing passage is closed and a position where the warehousing passage is opened.

Japanese Patent No. 3739151

  However, it is desirable to shorten the cord-like body (for example, wire rope) for suspending the gate body. It is also desirable to reduce the number of parts for raising and lowering the gate body.

  Therefore, an object of the present invention is to shorten the rope-like body and reduce the number of parts used in the front gate device that opens and closes the entry passage by suspending and raising the gate body with the rope-like body. It is in.

(1) In order to achieve the above object, according to the present invention, a front gate device in a mechanical parking device,
By being driven up and down, a gate body that opens and closes the entry passage for the car to enter the mechanical parking device,
An elevating device for elevating and lowering the gate body,
The lifting device is
A cord-like body having one end coupled to the gate body and extending upward from the one end to suspend the gate body;
A cord drive device that lifts and lowers the gate body via the cord by lifting and hanging the cord; and
A front gate device is provided in which the cords extend linearly in the vertical direction in the range from the one end to the cord drive device.

  In the above-described front gate device of the present invention, the gate body is suspended by the cable-shaped body, and the gate body is moved up and down by driving the cable-shaped body. In this case, the cord-like body extends linearly in the vertical direction in the range from the one end connected to the gate body to the upper cord-like body driving device. Therefore, the cord-like body is arranged without being hung on a driven pulley or a driven sprocket on the way. Therefore, the cord-like body for driving the gate body can be shortened, and it becomes unnecessary to provide a driven pulley.

  The above-described front gate device can be configured as follows, for example.

(2) In the above (1), the coupling position where the one end of the cord-like body is coupled to the gate body coincides with or is close to the center of gravity of the gate body in the horizontal width direction of the gate body. Yes.

(3) In the above (1) or (2), the front gate device described above includes a guide mechanism for guiding the raising and lowering of the gate body,
The guide mechanism has a first fitting portion and a second fitting portion that are fitted together,
The first fitting portion is provided at both ends of the gate body in the horizontal width direction of the gate body,
The second fitting portions are provided on both sides of the gate body in the horizontal width direction, and are fitted to the first fitting portions at both ends,
The first fitting part is movable in the vertical direction with respect to the second fitting part.

  Thus, the 1st fitting part of the both ends of a gate body is movable to the perpendicular direction with respect to the 2nd fitting part in the state fitted to the 2nd fitting part of the guide mechanism. Therefore, the gate body can be prevented from tilting from the reference posture (horizontal posture).

(4) In the above (1), the coupling position where the one end of the cord-like body is coupled to the gate body is shifted to one side from the center of gravity of the gate body in the horizontal width direction of the gate body. And
The front gate device described above includes a guide mechanism for guiding the raising and lowering of the gate body,
The guide mechanism has a first fitting portion and a second fitting portion that are fitted together,
The first fitting portion is provided at an end portion of the gate body in the horizontal width direction,
The second fitting portion is fitted to the first fitting portion,
The first fitting portion is movable in the vertical direction with respect to the second fitting portion while being pressed against the second fitting portion toward the one side or the other side in the horizontal width direction.

  In this configuration, since the coupling position is deviated from the center of gravity, a rotational moment about the coupling position is generated in the gate body due to its own weight. Thereby, the 1st fitting part will be in the state pressed against the 2nd fitting part to one side or the other side of the horizontal width direction. In this state, the gate body can be set to be in a horizontal posture. Therefore, the gate body can be raised and lowered while the gate body is stably maintained in the horizontal posture.

(5) In the above (4), in the gate body, the first fitting portion includes a first vertical position of an end located on the one side in the horizontal width direction and the other side in the horizontal width direction. At the second vertical position of the end located at
The first vertical position is a position below the vertical center of the gate body, and the second vertical position is a position above the vertical center of the gate body.

  With such an arrangement of the first fitting portion, the gate body can be stably maintained in a horizontal posture.

(6) In any one of the above (3) to (5), the first fitting portion is a roller attached to the gate body,
The roller is rotatable about a rotation axis horizontal to the gate body;
A groove is formed on the outer peripheral surface of the roller, and the groove extends so as to make one turn around the rotation axis.
The second fitting portion is a rail extending in the vertical direction, and the rail is fitted in the groove.

  In this configuration, the roller can roll on the rail in a state where the groove of the roller as the first fitting portion is fitted into the rail as the second fitting portion. Therefore, the second fitting portion can smoothly guide the raising and lowering of the first fitting portion.

(7) In any one of the above (3) to (6), the front gate device described above is configured such that one position of the first fitting portion and the second fitting portion is in the horizontal direction with the first fitting portion. An adjustment mechanism that can be adjusted with respect to the other of the second fitting portions is provided.

In this configuration, in the case of (3) above, the mutual position of the first fitting portion and the second fitting portion can be adjusted in the horizontal direction by the adjusting mechanism. Accordingly, the first fitting portion and the second fitting portion can be kept in contact with each other in the horizontal direction (pressing each other). That is, the first fitting portion and the second fitting portion can be maintained in a state of being fitted to each other without a gap. Thereby, the gate body can be kept stable and horizontal.
That is, even when the gate body is hung by one cable-like body extending in a straight line from the coupling position to the cable-like body drive device, there is no gap between the first fitting portion and the second fitting portion. Since it can be fitted, the gate body can be reliably and stably kept horizontal.

  On the other hand, in the cases (4) and (5), the posture of the gate body 5 can be adjusted by the adjusting mechanism.

(8) In the above (7), the adjustment mechanism includes a long hole provided in the gate body and extending in the horizontal width direction,
A bolt penetrating the elongated hole;
A nut that is screwed to one end portion of the bolt;
A first fitting portion is attached to the other end portion of the bolt,
The first fitting portion is fixed to the gate body by sandwiching the gate body between the nut and the other end portion of the bolt.

  In this configuration, the position of the bolt can be adjusted in the horizontal width direction along the long hole. Accordingly, the position of the first fitting portion fixed to the other end portion of the bolt can also be adjusted in the horizontal width direction along the long hole.

(9) In any one of the above (1) to (8), the cord is a wire rope or a chain.

  In the above-described front gate device of the present invention, the cord body for lifting and lowering the gate body extends linearly in the vertical direction in the range from the coupling position with the gate body to the upper cord body driving device. ing. Therefore, the cord-like body is arranged without being hung on a driven pulley or a driven sprocket on the way. Therefore, the cord-like body for driving the gate body can be shortened, and it becomes unnecessary to provide a driven pulley.

  Embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted.

<First Embodiment>
FIG. 1 is a plan view showing a front gate device 10 according to a first embodiment of the present invention. In FIG. 1, a region R surrounded by a broken line indicates a region in the mechanical parking device 20.

  In addition, in FIG. 1, illustration of the detailed structure of the mechanical parking apparatus 20 is abbreviate | omitted. Moreover, in FIG. 1, illustration of the support body 6 and the cord-like body drive device 7b which will be described later is omitted.

  The front gate device 10 is provided in the storage passage 2 in the mechanical parking device 20. The entry passage 2 is a passage for the automobile 1 to enter the entry position in the mechanical parking device 20. The parking device 20 is provided with a plurality of pallets 3 that are driven between the storage position and the storage position. The parking device 20 may be of any type as long as it has such a configuration. The parking device 20 may be, for example, a two-stage type (for example, the type described in Patent Document 1) or an elevator type, but may be of another type.

(Receipt operation)
The car 1 travels through the entry passage 2 and enters the pallet 3 at the entry position from the outside of the parking device 20. Thereafter, the person who gets out of the car 1 at the warehousing position goes out of the parking device 20 through the warehousing passage 2.

  Subsequently, the pallet 3 at the storage position may be driven to the storage position in the parking device 20. In this case, another pallet 3 on which the automobile 1 is not loaded is driven to the warehousing position. Another car 1 can enter the other pallet 3 from the outside of the parking device 20.

(Outgoing operation)
The entry passage 2 may also serve as an exit passage. In this case, the pallet 3 on which the car 1 to be delivered is placed is driven from the storage position to the entry position. Thereafter, a person passes through the entry passage 2 and gets into the automobile 1 on the pallet 3 at the entry position. Next, from this pallet 3, the automobile 1 travels to the outside of the parking device 20 through the entry passage 2.

(Configuration of front gate device)
FIG. 2A is a view taken in the direction of arrows IIA-IIA in FIG. The front gate device 10 opens and closes the warehousing passage 2 on the front surface of the parking device 20. FIG. 2A shows a state in which the front gate device 10 closes the entry passage 2. FIG. 2B is the same arrow view as FIG. FIG. 2 (B) shows a state where the front gate device 10 has opened the entry passage 2. FIG. 3A is a view taken in the direction of arrows IIIA-IIIA in FIG. FIG. 3B is a view taken along the line IIIB-IIIB in FIG. The entry passage 2 is a portion surrounded by a broken line in FIGS. 2B and 3A and 3B. The road surface of the entry passage 2 is indicated by reference numeral 2a.

  When the parking device 20 is operated (that is, when the pallet 3 is driven), the front gate device 10 closes the entry passage 2 as shown in FIG. Thereby, the front gate device 10 prevents a person or the vehicle 1 from entering the parking device 20 through the entry passage 2 during the operation of the parking device 20. On the other hand, when the car 1 or a person passes through the warehousing passage 2 during warehousing or unloading, the front gate device 10 opens the warehousing passage 2 as shown in FIG.

  The front gate device 10 includes a gate body 5, a lifting device 7, a guide mechanism 9, and an adjustment mechanism 11.

  The gate body 5 opens and closes the warehousing passage 2 by being driven up and down.

  The elevating device 7 elevates and lowers the gate body 5. The lifting device 7 includes a cord 7a and a cord driving device 7b.

  The cord-like body 7 a suspends the gate body 5. The cord 7a has one end 7a1 coupled to the gate body 5. The cord 7a extends upward (vertical direction) from the one end 7a1 to the cord driving device 7b. The cord 7a extends linearly from the one end 7a1 to the cord driving device 7b.

  The cord-like body driving device 7b moves the gate body 5 up and down via the cord-like body 7a by driving (raising and hanging) the cord-like body 7a. The cord driving device 7 b is provided on the support 6 positioned above the gate body 5. In the example of FIG. 2, the support 6 is a member that is stretched over the upper ends of the two columnar members 8.

  In the example of FIGS. 2 to 4, the cord-like body 7 a is a wire rope. In this case, the cord driving device 7 b includes a motor 13 and a drum 15 that is rotationally driven by the motor 13. In the example of the drawing, the output shaft of the motor 13 is directly connected to the drum 15 coaxially. However, the motor 13 may rotationally drive the drum 15 via a speed reducer. The wire rope 7 a extends upward from the one end 7 a 1 to the drum 15. As the drum 15 rotates, the drum 15 rewinds or unwinds the cord 7a. Thereby, the gate body 5 moves up and down.

  One end portion 7 a 1 of the cord-like body 7 a is coupled to the gate body 5 at the coupling position P in the gate body 5. The coupling position P coincides with or is close to the center of gravity of the gate body 5 in the horizontal width direction D of the gate body 5 (the direction of the arrow D shown in FIG. 1). Preferably, the coupling position P is the center of the gate body 5 in the horizontal width direction D or a close position of this center.

  The guide mechanism 9 guides the raising and lowering of the gate body 5. The guide mechanism 9 includes a first fitting portion 9a and a second fitting portion 9b that are fitted to each other.

  The first fitting portions 9 a are provided at both ends of the gate body 5 in the horizontal width direction D. The second fitting portions 9b are provided on both sides of the gate body 5 in the horizontal width direction D. Each 2nd fitting part 9b is being fixed to the stationary structure (for example, structure which forms the road surface 2a of the channel | path 2 for warehousing). In the horizontal width direction D, the first fitting portion 9a of one end of the gate body 5 (the right end of FIG. 2A) is the first fitting portion 9a on the one side in the horizontal width direction D (the right side of FIG. 2A). 2 is fitted to the fitting portion 9b. In the horizontal width direction D, the first fitting portion 9a of the other end portion (the left end portion in FIG. 2A) of the gate body 5 is on the other side in the horizontal width direction D (the left side in FIG. 2A). The second fitting portion 9b is fitted.

  The first fitting portion 9a is movable in the vertical direction with respect to the second fitting portion 9b while being fitted with the second fitting portion 9b. On the other hand, the horizontal movement of the first fitting portion 9a with respect to the second fitting portion 9b is restricted by the second fitting portion 9b. Accordingly, the vertical movement (lifting) of the first fitting portion 9a is guided to the second fitting portion 9b. If the guide mechanism 9 has such a function, the configuration of the first fitting portion 9a and the second fitting portion 9b is not limited to the specific configuration shown in the drawings and the following description.

  FIG. 4A is a partially enlarged view of FIG. FIG. 4B is a view taken along arrow BB in FIG. FIG. 4C is a CC arrow view of FIG.

  In the first embodiment, as shown in FIG. 4, the first fitting portion 9a is a roller attached to the gate body 5, and the second fitting portion 9b is a rail extending in the vertical direction. The roller 9 a is rotatable around a rotation axis C that is horizontal with respect to the gate body 5. A groove 9a1 is formed on the outer peripheral surface of the roller 9a. The groove 9a1 extends so as to make one turn in the circumferential direction around the rotation axis C. The rail 9b is fitted in the groove 9a1 of the roller 9a. In this state, the roller 9a can roll on the rail 9b in the vertical direction. In the example of FIG. 4, the rail 9 b is formed as a part of a columnar member 8 having an H-shaped cross section.

  2 to 4, in the gate body 5, the first fitting portion 9 a includes the first vertical direction position Pz <b> 1 and the second vertical direction position Pz <b> 2 at one end portion in the horizontal width direction D, and the horizontal width direction D. It is provided at the first vertical direction position Pz1 and the second vertical direction position Pz2 at the other end. The first vertical position Pz1 and the second vertical position Pz2 are positions (heights) in the vertical direction. The first vertical direction position Pz1 is a position below the center of the gate body 5 in the vertical direction, and the second vertical direction position Pz2 is a position above the center of the gate body 5 in the vertical direction. Preferably, the first vertical position Pz1 is the position of the lower end of the gate body 5, and the second vertical position Pz2 is the position of the upper end of the gate body 5.

  2 to 4, the number of the first fitting portions 9a may be two. For example, the first fitting portions 9a may be provided only at both ends of the gate body 5 in the horizontal width direction D, which is one of the first vertical direction position Pz1 and the second vertical direction position Pz2. . Alternatively, the first fitting portions 9a may be provided only at one end portion of the gate body 5 in the horizontal width direction D and only at the first vertical direction position Pz1 and the second vertical direction position Pz2.

  The adjustment mechanism 11 is configured so that one of the first fitting portion 9a and the second fitting portion 9b is positioned in the horizontal direction (in this example, the horizontal width direction D), the first fitting portion 9a and the second fitting portion. It is adjustable with respect to the other of 9b.

  The adjustment mechanism 11 includes, for example, a long hole 11a, a bolt 11b, and a nut 11c. The long hole 11 a is formed in the gate body 5. The long hole 11 a passes through the gate body 5 in the thickness direction of the gate body 5. This thickness direction is a horizontal direction orthogonal to the horizontal width direction D. Further, the long hole 11a is elongated in the horizontal width direction D. The bolt 11b is arrange | positioned so that the long hole 11a may be penetrated. The nut 11c is screwed to one end side portion of the bolt 11b. A first fitting portion 9a is attached to the other end portion of the bolt 11b. When the 1st fitting part 9a is the above-mentioned roller, the roller 9a is rotatable around the above-mentioned rotation axis C in a state of being attached to the other end portion of the bolt 11b. Such an adjustment mechanism 11 is provided in each 1st fitting part 9a.

  In adjusting the position of the first fitting portion 9a by the adjusting mechanism 11, the tightening of the nut 11c to the bolt 11b is loosened. In this state, the position of the bolt 11b can be adjusted in the horizontal width direction D with respect to the gate body 5 along the long hole 11a. Therefore, the position of the first fitting portion 9a attached to the bolt 11b can also be adjusted. After this adjustment, the nut 11c is fastened to the bolt 11b, and the gate body 5 is sandwiched between the nut 11c and the other end portion of the bolt 11b. Thereby, the 1st fitting part 9a is fixed to the gate body 5. FIG.

(Effect by 1st Embodiment)
In the front gate device 10 according to the first embodiment described above, the gate body 5 is suspended by a single cord-like body 7a, and the gate body 5 is moved up and down by driving the cord-like body 7a. In this case, the coupling position P at which the one end portion 7a1 of the cord-like body 7a is coupled to the gate body 5 coincides with or is in the center of gravity of the gate body 5 in the horizontal width direction D of the gate body 5. It is close. Therefore, the cord-like body 7a is arranged so as to extend in a straight line from the coupling position P to the cord-like body driving device 7b without being hooked on the driven pulley in the middle. Therefore, the cord-like body 7a for driving the gate body 5 can be shortened, and it becomes unnecessary to provide a driven pulley.

  Further, since the wire rope 7a is not hung on the driven pulley, the wire rope 7a is not worn by the driven pulley. On the other hand, conventionally, since the wire rope for suspending the gate body is hung on a plurality of driven pulleys, the wire rope or the driven pulley is worn. This problem is solved by the configuration of the first embodiment.

Second Embodiment
FIG. 5 is a plan view showing the front gate device 10 according to the second embodiment. FIG. 6A is a view taken along the arrow VIA-VIA in FIG. FIG. 6 (B) is the same arrow view as FIG. 6 (A) and shows a state in which the gate body 5 has opened the entry passage 2. FIG. 7A is a view taken in the direction of arrows VIIA-VIIA in FIG. FIG. 7B is a view taken along arrow VIIB-VIIB in FIG.

  Hereinafter, a second embodiment will be described based on FIGS. The configuration and operation of the second embodiment, which will not be described below, are the same as those of the first embodiment.

  As shown in FIG. 6A, when the gate body 5 is in the raised position, the gate body 5 closes the entry passage 2. At this time, the gate body 5 is positioned above the road surface 2a of the entry passage 2.

  On the other hand, as shown in FIG. 6B, when the gate body 5 is in the lowered position, the gate body 5 opens the warehousing passage 2. At this time, the gate body 5 is located below the road surface 2 a of the entry passage 2. For this purpose, a lower space S is provided for accommodating the gate body 5, a part of the second fitting portion (rail) 9b, the cord-like body driving device 7b, and the like.

  The lower space S is located below the road surface 2 a of the warehousing passage 2. The lower space S has an opening to the road surface 2 a of the warehousing passage 2. Through this opening, the gate body 5 is moved up and down. In addition, the support body 6 on which the cord-like body driving device 7b is provided is positioned below the road surface 2a of the entry passage 2. That is, the support 6 is also located in the lower space S.

  Preferably, one end portion 7 a 1 of the cord-like body 7 a is coupled to the coupling position P at the lower end portion of the gate body 5. In the second embodiment, the same effect as in the first embodiment can be obtained.

  The present invention is not limited to the above-described embodiment, and various changes can be made without departing from the scope of the present invention. For example, in the first embodiment or the second embodiment, any one of the following modifications 1 to 4 may be employed, or two or more of the modifications 1 to 4 may be arbitrarily combined and employed. . In this case, the points not described below are the same as described above.

(Modification 1)
The cord 7a may be a chain. In this case, the cord driving device 7 b has a sprocket instead of the drum 15. A chain is hung on the sprocket. The chain extends upward from the one end 7a1 and is hung on the sprocket. The chain is suspended and driven (driven up and down) by the rotation of the sprocket. Thereby, the gate body 5 moves up and down.

(Modification 2)
The adjustment mechanism 11 is configured so that one of the first fitting portion 9a and the second fitting portion 9b is positioned in the horizontal direction (horizontal width direction D) with the first fitting portion 9a and the second fitting portion by another configuration. It may be adjustable with respect to the other part 9b. For example, the adjustment mechanism 11 may have the configuration shown in FIG. FIG. 8 is the same arrow view as FIG. FIG. 8 shows a case where the adjusting mechanism 11 has a configuration different from that in FIG.

  In FIG. 8, the adjusting mechanism 11 includes a screw hole forming portion 11d, a screw 11e, and a mounting portion 11f. The screw hole forming portion 11 d is fixed to the gate body 5. A threaded hole penetrates the threaded hole forming portion 11d in the horizontal width direction D. A female screw 11d1 is formed on the inner peripheral surface of the screw hole. The screw 11e is screwed into the female screw 11d1 of the screw hole. A mounting portion 11f is fixed to the tip of the screw 11e. A first fitting portion 9a is attached to the attachment portion 11f. A screwdriver is engaged with the rear end of the screw 11e, and the screw 11e is rotated by the screwdriver. Accordingly, the position of the first fitting portion 9a with respect to the second fitting portion 9b is adjusted in the horizontal width direction D.

  Moreover, the direction of the 1st fitting part 9a and the 2nd fitting part 9b is not limited to the example of each figure. That is, the orientation of the first fitting portion 9a and the second fitting portion 9b may be in a direction orthogonal to these orientations shown in each drawing (for example, the rotation axis C faces the horizontal width direction D). May be). In this case, the adjustment mechanism 11 places the first fitting portion 9a and the second fitting portion in the horizontal direction orthogonal to the horizontal width direction D with respect to one position of the first fitting portion 9a and the second fitting portion 9b. It can be adjusted with respect to the other of the joint part 9b.

(Modification 3)
FIG. 9 is a front view of the front gate device 10 according to the third modification. In the modified example 3, the above-described coupling position P (one end 7a1 of the cord-like body 7a) is shifted from the center of gravity G of the gate body 5 to one side in the horizontal width direction D of the gate body 5. In FIG. 9, the coupling position P is shifted to the left from the center of gravity G.

  In the example of FIG. 9, two first fitting portions 9 a are provided on the gate body 5. One first fitting portion 9a is at a first vertical position Pz1 at the end of the gate body 5 on one side in the horizontal width direction D (left side in FIG. 9). The other first fitting portion 9a is located at the second vertical position Pz2 at the end of the gate body 5 on the other side in the horizontal width direction D (the right side in FIG. 9). Preferably, only these two are provided as the first fitting portion 9a. However, according to the present invention, one of these two first fitting portions 9a may be omitted (that is, only one first fitting portion 9a may be provided). In this case, the second fitting portion 9b into which the omitted first fitting portion 9a is fitted may also be omitted.

  Preferably, the first vertical position Pz1 is the position of the lower end of the gate body 5, and the second vertical position Pz2 is the position of the upper end of the gate body 5.

  In the third modification, a rotational moment is generated in the gate body 5 due to its own weight. This rotational moment is generated in the clockwise direction around the coupling position P in FIG. Thereby, the 1st fitting part 9a is pressed by the 2nd fitting part 9b to the one side of the horizontal width direction D, or this other side (namely, the other side). In this state, the first fitting portion 9a is movable in the vertical direction with respect to the second fitting portion 9b. In the example of FIG. 9, the left first fitting portion 9 a is pressed against the second fitting portion 9 b toward one side in the horizontal width direction D (left side in FIG. 9). In the example of FIG. 9, the first fitting portion 9a on the right side is pressed against the second fitting portion 9b to the other side in the horizontal width direction D (right side in FIG. 9).
