Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an automatic ticket gate, and more particularly to an automatic ticket gate in which a card handler can be moved up and down.

[0002]

[Prior art]

 Conventionally, card handlers (hereinafter referred to as handlers) for processing cards, such as tickets, entrance tickets, prepaid cards, and stored fair cards, which are inserted into automatic ticket gates, clean and transport magnetic heads and various sensors. It is installed so that it can be lifted upward from the main body of the automatic ticket gate (hereinafter referred to as “main body”) for maintenance and inspection such as belt replacement.

The following is known as the lifting mechanism. The handle provided on the handler is lifted by two workers and moved to a location away from the main unit for maintenance and inspection. As an improvement of the above, a support rod is interposed between the handler and the main body in order to maintain the state by manually lifting it to a position where maintenance and inspection are possible (Japanese Utility Model Application No. 48-108056). The above support rod is rotated via a worm and a worm gear, and direct lifting by human power is omitted (Japanese Patent Laid-Open No. 48-81600).

[0004]

[Problems to be solved by the invention]

 However, in the above-mentioned conventional and conventional methods, the weight of the handler is several tens of kilograms, the lifting and moving work is heavy labor, and there are disadvantages that two workers are required.

Further, in the above, since the support rod is rotated about the same axis as the worm gear, a large force is required for the rotational force of the worm, so that labor cannot be reduced. The rotation of the shaft around the axis causes the tip of the support rod to move in a circular motion, and therefore the handler on the tip of the support rod can also be lifted in a circular motion, so that the body structure has a complicated structure suitable for the circular motion. There was a drawback that had to be done.

Therefore, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide an automatic ticket gate that can lift a handler vertically above a main body with a simple structure. is there.

It is characterized by the following.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an automatic ticket gate a according to an embodiment, in which a part of a side cover of a main body 1 is cut away and a handler elevating device provided in the main body 1 is shown. It is. The right half of FIG. 1 shows a state in which the handler H is lowered to a steady position and is set on the main body 1, and the left half thereof is a position where the elevator H can be operated to maintain and inspect the handler H. It shows a state where it has been lifted up.

The main body 1 has vertical frames 2a and 2b on the left and right end sides, and a horizontal frame 2c extends between the two vertical frames.

At the center of the upper surface of the horizontal frame 2c, there is provided a screw rod 3 extending in parallel with the longitudinal direction of the horizontal frame and having male screws 3a and 3b of square threads having different helical directions on the left and right sides. It is rotatably supported by bearings 4a and 4b. A pair of moving bodies 6a and 6b having female threads 5a and 5b are screwed into the male threads 3a and 3b on both sides of the screw rod 3.

As shown in a plan view in FIG. 2, the moving body 6a has a box-like shape in which a lower surface and one side wall (left side wall in the illustrated example; right side wall in the moving body 6b) are omitted. ing. The above-described female screw 5a is fixed to the other side wall 7a of the moving body 6a. Rollers 9a, 9b are supported by pins 8a, 8b on the front and rear walls 7b, 7c of the moving body 6a together with connecting rods 16a, 16b described later.

On both front and rear sides of the upper surface of the horizontal frame 2c, rails 10a and 10b extending in parallel with the screw rod 3 are provided so that the rollers 9a and 9b can move in the left and right directions on the rails 10a and 10b. .

The moving body 6b has the same configuration as the moving body 6a, and is symmetrically arranged. Therefore, the rollers 11a and 11b corresponding to the rollers 9a and 9b are rotatably provided by the pins 12a and 12b, and these rollers are mounted on the rails 13a and 13b corresponding to the rails 10a and 10b. It is placed on.

The gantry 14 mounts the handler H, and is located between the two vertical frames 2a and 2b above the horizontal frame 2c.

As shown in FIG. 3, the guide rollers 15a and 15b provided at both ends of the gantry 14 are guided by the guide rollers by rollingly contacting the vertical frames 2a and 2b. It is movable vertically between the two vertical frames 2a and 2b.

The connecting rods 16a, 16b are composed of a pair of rods whose upper ends are pivotally supported by front and rear walls 17a, 17b at both ends of the gantry 14 by pins 18a, 18b, and whose lower ends are the rollers 9a, 9b, 11a. , 11b are supported by pins 8a, 8b, 12a, 12b, respectively.

FIG. 4 shows a rotation driving means for driving the screw rod 3 to rotate. That is, a bevel gear 19 is fixed to the tip of the screw rod 3, and another bevel gear 20 is meshed with this bevel gear. The rotating shaft 21 of the bevel gear 20 is supported at right angles to the screw rod 3 by a pair of bearings 22a and 22b arranged on both sides of the bevel gear 20. At one end of the rotating shaft 21, a concave portion 23 for connecting a handle 24 described later is formed.

Reference numeral 24 denotes a crank-shaped handle for inputting a rotational force to the rotating shaft 21. The handle 24 is inserted through a hole 25 opened in the side case 1a of the main body 1 and provided at the front end. It is configured such that the provided convex portion can be engaged with the concave portion 23.

A recess 24 may be provided at one end of the threaded rod 3, and a handle may be inserted into a hole of the main body from above the extension of the threaded rod, coupled with the threaded rod, and rotated.

Hereinafter, the operation of the automatic ticket gate a configured as described above will be described. At the time of maintenance / inspection of the handler H of the automatic ticket gate a, the operator inserts the handle 24 into the hole 25 of the side case 1a, connects the handle 24 to the rotating shaft 21, and then rotates the handle in a predetermined direction. As a result, the screw rod 3 is rotated in a predetermined direction via both bevel gears 19 and 20.

By the rotation of the screw rod 3, the two moving bodies 6a, 6b move in the direction away from each other (the side of the vertical frames 2a, 2b) via the female screws 5a, 5b screwed into the screw rod 3. When the moving bodies 6a and 6b move outward, the lower ends of the connecting rods 16a and 16b move similarly. In other words, the state changes from the right side to the left side in FIG. Thus, the gantry 14 is guided by the guide rollers 15a and 15b, and smoothly rises vertically between the two vertical frames 2a and 2b.

At this time, the weight of the gantry 14 on which the handler H is mounted is received by the rails 10 a, 11 b, 13 a, 13 b by the rollers 8 a, 8 b, 11 a, 11 b and added to the screw rod 3. Not. Therefore, a small rotating force needs to be applied to the handle 24.

When the gantry 14 rises, the handler H is lifted above the main body 1 and maintenance and inspection are performed by a staff member.

When the handle 24 is rotated in the reverse direction after the maintenance / inspection of the handler H, the screw rod 3 rotates in the opposite direction to that described above, so that the moving bodies 6a and 6b move closer to the center. Therefore, the upper ends of the connecting rods 16a and 16b are lowered. Thereby, the gantry 14 descends as shown on the right side of FIG. 1, and the handler H is set at the original position.

As described above, the automatic ticket gate according to one embodiment of the present invention moves the screw bar 3 rotated by the handle 24 so as to approach each other by one rotation of the screw bar 3. The moving bodies 6a and 6b are provided so as to move and separate from each other by the other rotation, and the lower ends of the connecting rods 16a and 16b are pivotally supported by the moving bodies 6a and 6b. The moving bodies 6a and 6b 9b and 11a, 11b are mounted on the rails 10a, 10b, 13a, 13b, and the upper ends of the connecting rods 16a, 16b are pivotally supported by the mount 14 on which the handler H is mounted. Can be received by the rollers 9a, 9b, 11a, 11b, and the rotational force of the screw rod 4 can be reduced. Therefore, the handle 24 can be quickly rotated, and the handler H can be moved up and down very easily.

Moreover, since the guide rollers 15a and 15b are provided at both ends of the gantry 14, the gantry 14 can be smoothly moved between the vertical frames 2a and 2b.

FIG. 5 shows another driving means for rotating the screw rod 3. That is, a coupling 30 is provided at one end of the screw bar 3, and a drive shaft 33 of a reversible motor 32 having a speed reducer 31 is connected via the coupling.

Accordingly, by rotating the reversible motor 32 in a predetermined direction or a direction opposite thereto by a selection switch (not shown), the screw rod 3 can be rotated in an arbitrary rotation direction. In addition, since this rotational force requires only a small rotational force as described above, it can be realized by a small-capacity reversible motor.

As described above, when the screw rod 3 is rotated by the reversible motor 32 instead of the handle 24, the operator can quickly move the handle H up and down simply by operating the selection switch. Maintenance and inspection can be performed promptly.

In the above example, the pivots of the moving bodies 6a, 6b at the lower ends of the connecting rods 16a, 16b are shared with the pins 8a, 8b, 12a, 12b of the rollers 9a, 9b, 11a, 11b. However, you may make it support by a separate pin.

[Effect of the invention]

 The automatic ticket gate according to the present invention is provided with moving bodies on both sides of the screw rod so as to move closer to each other by one-way rotation of the screw rod and to move away from each other by rotation in the other direction, and to provide a connecting rod Since the lower end of the connecting rod is rotatably supported by the moving body, the roller has a roller mounted on the rail, and the upper end of the connecting rod is rotatably supported by the mount on which the handler is mounted. Since the weight of the gantry can be received by the moving body, the rotational force of the screw rod for moving the moving body in the horizontal direction can be reduced. For this reason, the screw rod can be rotated quickly, so that the platform on which the handler is mounted can be moved up and down very easily.
