Description

  The present invention relates to a gate device installed at entrances and exits of various facilities and event venues.

  The gate device is used, for example, to allow only a specific authorized person to pass, or simply to switch between a passable state and a non-passable state. There are ticket gates and entrance gates for paid venues. In the former case, a magnetic or IC card or ticket is used as the confirmation means.

  The gate device includes a gate unit having a horizontally rotating (turning) type gate (door) on a long and narrow partition in a plan view, and a plurality of gate units are arranged side by side between adjacent gate units. It forms a passage, and this passage is opened and closed by the horizontal rotation of the gate, but when viewed from the relationship between the opening and closing of the passage and the gate, the single-opening type that opens and closes one passage with only one gate For example, as described in Patent Documents 1 and 2, there is a double door type that opens and closes one passage by simultaneously rotating two gates provided in two adjacent gate units.

Various means such as a combination of a circular cam and a roller are employed as means for selectively holding the gate in the passage closing posture and the passage opening posture. In the case of Patent Document 2, the rotary shaft is driven through a link group by a reciprocating solenoid, but it seems that the posture of the link is maintained by devising the form of the link.

  By the way, in this type of gate device, the gate is rotated at a considerable speed, and therefore, a large inertial force acts upon stopping. For this reason, for example, when the gate shifts from the closed passage position to the open passage position, it often stops in a state of a bang and generates a large impact and collision noise. This causes discomfort to the person and durability of the member. There was a problem that there was a concern that the performance would be lowered.

  This invention makes it a subject to eliminate such a problem.

The invention of the present application is a gate device for forming a human passage, wherein a gate is attached to a rotary shaft that rotates horizontally, and a peripheral cam on which a roller contacts the outer periphery is fixed to the rotary shaft, the peripheral surface cam, and the roller is fitted fitting portion when the gate opened posture a person passable passageway, the roller when the gate closed position the person is impassable the passage and a fitting portion to be fitted It is formed and, and the roller is biased in a direction which corresponds to the outer peripheral surface of the peripheral face cam by a spring, in the configuration of the portion adjacent to said fitting portion of said peripheral surface cam, in the circumferential direction distance from the rotation center forms the larger projections toward the said fitting portion along.

  With this configuration, when the roller transitions from the cam surface to the fitting portion in the transition from the closed posture to the open posture, or in the transition from the open posture to the closed posture, the presence of the protrusion portion prevents the rotation shaft from rotating. Since the resistance increases, a kind of damper effect or cushion effect is exhibited, and the rotation of the rotating shaft can be stopped slowly (the motor is decelerated when the roller passes over the protrusion).

  This prevents or significantly suppresses the gate from rotating and stopping due to a bang and impact when holding the gate in a closed passage or open passage posture, and ensures quietness of gate opening and closing and improved durability of members. It can be done.

  In addition, since an impact is generated when the gate shifts to the passage opening posture, at least the gate is shifted from the passage closing posture to the passage opening posture by increasing the resistance by projecting the vicinity of the fitting portion of the circumferential cam. It should be provided to function at the end of the time.

  Next, an embodiment of the present invention will be described with reference to the drawings.

(1). Outline of First Embodiment FIGS. 1 to 6 show the first embodiment. 1 is a schematic perspective view of the entire gate device group, and FIG. 2 is a plan view of the entire gate device group. The gate device group includes a plurality of gate units 2 and 3 each having an elongated partition 1 in plan view. By configuring the plurality of gate units 2 and 3 in parallel, a passage 4 through which one person can pass is formed between the adjacent gate units 2 and 3. In the following description, the term “left and right” is used, but the left and right are based on the posture of a person passing through the passage 4.

  A unit gate device 5 is constituted by two adjacent gate units 2 and 3, and this unit gate device 5 corresponds to the gate device described in claim 1. Further, the unit gate devices 5 adjacent to each other on the left and right share one gate unit 3.

  The gate units constituting both ends of the gate device group are denoted by reference numeral 2 as end gate units 2, and the gate units disposed between the end gate units 2 are denoted by reference numeral 3 and are indicated as intermediate gate units 3. is doing. When there is no need to distinguish between the two, they are simply displayed as gate units 2 and 3.

  Each of the gate units 2 and 3 has a gate 6 for opening and closing the passage 4 at a position on the left and right wide surfaces of the partition 1 so as to be horizontally rotatable, but the intermediate gate unit 3 has passages 4 on both sides thereof. Therefore, while the pair of gates 6 are attached to the left and right wide surfaces of the partition 1, the end gate unit 2 has the gates 6 attached to only one side facing the passage 4. The gate units 2 and 3 basically have the same form and structure, and it is possible to attach the gate 6 to the left and right wide surfaces in the end gate unit 2 (the passage 4 is the gate on the opposite side). If you don't use 6).

  The partition 1 of each of the gate units 2 and 3 is covered with a cover plate 7 and is formed in a hollow shape, and visually indicates whether or not it can enter the front part 8 constituting both front and rear ends. An entry guide unit 9 is provided, and a card reader 10 is provided above the entry guide unit 9. The front / rear card reader 10 has a shape protruding upward, a transparent or opaque plate member 11 is disposed between the front / rear card reader 10, and portions on both front and rear sides thereof serve as lighting-type traffic confirmation portions 11 a. .

The traffic confirmation unit 11a displays whether or not traffic is appropriate, and can emit light in any color such as red, blue, and purple. For example, the card is inappropriate or the card is not used. It is set to light up when trying to pass. Needless to say, the card reader 10 can adopt a contact type or a non-contact type depending on the type of card used (of course, both may be provided).

  The front part 8 is formed in a trapezoidal shape in which the distance between the left and right sides becomes narrower toward the front and rear and the outer side in a plan view, the approach guide part 9 is separated on the left and right with the longitudinal center line of the front part 8 interposed therebetween, and It extends to the surface that enters the passage 4. The approach guide 9 can be selectively lit in blue (blue or green) and red, for example, by a built-in lamp, and the passage 4 facing the approach guide 9 can be passed to the person who wants to pass. It can be made to visually recognize whether it is. In this embodiment, the approach guide part 9 is also improved, and this point will be described later.

  The portions of the left and right wide surfaces of the partition 1 are rectangular recesses 12 that are recessed inwardly between the front and rear front portions 8, and the gate 6 is opened so that a person can pass through the passage 4. It enters the inside of the recess 12 in a state of being retracted. The front-rear width dimension and the vertical width dimension of the recess 12 can be arbitrarily set according to the size of the gate 6.

  The gate 6 is attached to a rotating shaft 13 disposed substantially in the middle of the recess 12 in the front-rear direction so as to be horizontally rotatable. In this case, the passage 4 can be rotated in both the front and rear directions of the rotary shaft 13 in a passage opening posture (retracting posture) with the passage 4 open, and therefore one gate 6 is provided on one side of the partition 1. Although it is the type provided, the passage 4 can pass in either direction. Needless to say, the gate 6 rotates toward the front side in the direction of human movement.

  In the intermediate gate unit 3, as shown in FIG. 2, the rotating shafts 13 of the left and right gates 6 are arranged so as to be shifted on both sides with a horizontally long center line 14 dividing the partition 1 in the front-rear direction. The dimension in which the left and right gates 6 are shifted back and forth is set to be larger than the thickness of the gate 6. Accordingly, in the unit gate device 5, the ends of the left and right gates 6 are closed when the left and right gates 6 partition the passage 4. The planes are shifted in the front-rear direction without facing each other. In other words, there is an appropriate gap E between the tips of the left and right gates 6 in the closed state.

  Since the left and right gates 6 are displaced back and forth in this closed state, the width W of the passage 4 can be narrowed as described in the effect of the invention (extremely speaking, it is close to the laterally projecting dimension of the gate 6). In other words, the gate 6 is allowed to rotate and the safety can be ensured even if a hand or an object is sandwiched between the distal ends of the left and right gates 6.

(2). Gate Mounting Structure Details of the gate 6 mounting structure will be described with reference to FIGS. 3 is a side view of the intermediate gate unit 3, FIG. 4 is a front view of the gate device group, FIG. 5A is a partially broken side view, and FIG. 6B is a cross-sectional view taken along line VB-VB in FIG. 6A is a cross-sectional view taken along the line VIA-VIA of FIG. 5A, and FIG. 6B is a partially enlarged view of FIG.

  The gate 6 is made of, for example, a synthetic resin and has a substantially rectangular shape. The gate 6 is fixed to the rotary shaft 13 so as not to be relatively rotatable by means such as screwing or key engagement. The gate 6 has a large number of holes, which is intended to suppress air resistance during opening and closing. Needless to say, the gate 6 can adopt an arbitrary form such as a semicircular tip portion, and can be formed in a lattice shape or a simple frame shape. .

  As shown in FIG. 3, the partition body 1 includes upper and lower base frames 16 and 17 constituting the framework. As shown in FIG. 5A, the rotating shaft 13 is connected to the upper base frame 16. A fixed upper base 18 and a lower base 20 fixed to a first bracket 19 fixed to the lower base frame 17 are rotatably attached. The rotary shaft 13 is directly connected to a main shaft of a motor 21 fixed to the lower base 20 via a joint (coupling) 22.

  In the intermediate gate unit 3, there are two rotation shafts 13 and two motors 21 on the left and right, but the left and right rotation shafts 13 and the motors 21 are shifted in the front-rear direction.

  The upper part of the rotating shaft 13 protrudes above the upper base 18, and a rotating position holding cam 23 and a three-stage dog 24 for detecting the rotating position are fixed to the upward protruding part so as not to be relatively rotatable. Further, the upper end portion is connected to the detection shaft of the rotary encoder 25. The rotary encoder 25 is fixed to a third bracket 26 fixed to the upper base frame 16.

A three-stage limit switch 27 having a contact (not shown) that contacts the outer peripheral surface of the dog 24 is fixed to the upper surface of the upper base frame 16. Limit switch 27, by the rotation of the dog 24, and detects a passage closing position (posture crosses the passage 4) and passing path opened posture of the gate 6 (retracted position), controls the motor 21 by the limit switch 27 To do. The rotary encoder 25 is a kind of emergency stop means. When the limit switch 27 loses its function, the motor 21 is stopped based on the degree of rotation of the rotary shaft 13 detected by the rotary encoder 25. Yes.

  The cam 23 is a circular circumferential cam, and the posture of the gate 6 is selectively held by fitting the roller 31 into arcuate fitting portions 28 and 29 formed on the outer circumferential surface. .

That is, the roller 31 is attached to a laterally extending portion 33 a of an arm 33 attached to a pivot shaft 32 provided on the upper base frame 16 so as to be horizontally rotatable, and is fixed to the upper base frame 16. The roller 31 is urged by the tension spring 35 mounted on the fourth bracket 34 and the arm 33 so as to elastically contact the outer peripheral surface of the cam 23, while the gate 6 The first fitting portion 28 into which the roller 31 is fitted when the passage 6 is in the passage closing posture across the passage 4 and the roller 31 when the gate 6 is in the passage opening posture (retracting posture) into the recess 12 of the partition 1. By forming the two second recesses 29 into which the gates fit, the gate 6 is selectively held in the passage closing posture and in either the forward or backward passage opening posture.
And the part which adjoined the fitting parts 28 and 29 among the cam surfaces 37 is made into the projection part 37a from which the distance R from a rotation center becomes large as the fitting parts 28 and 29 are approached. If comprised in this way, when the roller 31 transfers to the fitting parts 28 and 29 from the cam surface 37, since resistance with respect to rotation of the rotating shaft 13 becomes large by presence of the projection part 37a, a kind of damper effect or cushion effect is produced. As a result, the rotation of the rotary shaft 13 can be stopped slowly.

  Since the gate 6 is rotated 90 degrees on both sides of the passage closing posture, the circumferential interval between the first recess 28 and the second recess 29 is 90 degrees. Further, the arm 33 to which the roller 23 is attached is arranged horizontally and horizontally from the viewpoint of space efficiency.

  Needless to say, the left and right rotating shafts 13 and the motor 21 divide the partition body 1 left and right at symmetrical positions with the horizontal center line 14 dividing the partition body 1 forward and backward. They are arranged at symmetrical positions across the vertically long center line 36. By shifting the rotating shaft 13 and the motor 21 back and forth, the horizontal width of the partition 1 can be reduced, space can be used effectively, and the amount of members used can be reduced to reduce costs.

  The actuator direct connection system in which the main shaft of the motor 23 and the main shaft of the rotary solenoid are directly connected to the rotary shaft 13 has the advantage of simplifying the structure, but the actuator is installed compared to the case where an electric mechanism such as a gear or belt is used. The flexibility of a place becomes low, and for this reason, if the actuator is provided side by side, the left-right width dimension of the partition 1 will become large. On the other hand, when configured as in the present invention, even if the rotary shaft 13 is directly connected to the main shaft of the motor or the like, the actuators can be arranged on the left and right without increasing the left and right width dimensions of the partition 1. The present invention is particularly useful in a system in which the rotary shaft 13 and the actuator are directly connected.

  In addition, since an impact is generated when the gate 6 shifts to the passage opening posture, the resistance applying means or the resistance increasing means functions at least at the end when the gate 6 shifts from the passage closing posture to the passage opening posture. Should be provided.

  Needless to say, the resistance applying means or the resistance increasing means can be widely applied to gate devices in general regardless of the arrangement of the gates.
