Description

The present invention relates to an inclination adjustment system for a pachinko gaming machine. More specifically, when installing a pachinko gaming machine on an island frame, the inclination can be finely adjusted with a simple operation, and the inclination can be finely adjusted on the island frame. On the other hand, the present invention relates to an inclination adjustment system for pachinko gaming machines, which can firmly lock the pachinko gaming machine to prevent it from tipping over and does not take up space for installation.

The pachinko gaming machine is composed of a pachinko underframe that is directly attached to the inside of the island frame and a pachinko main body that is installed inside the underframe. When installing this pachinko game machine on the island frame, the pachinko body and the underframe are separated, and the underframe is first fitted and fixed in the island frame, and then the pachinko body is used as a hinge on the underframe. To install. The underframe is fixed to the island frame by fitting the underframe into the island frame so as to be substantially vertical, nailing the upper and lower sides thereof, and fixing the underframe to the island frame by screwing or the like. Then, after the pachinko main body is installed on the underframe, the inclination angle of the pachinko main body is adjusted.

Various tilt adjustment systems have been proposed for automatically adjusting the tilt angle of the pachinko body. For example, in Japanese Patent Application Laid-Open No. 2006-192159, a pair of units that bite into the upper or lower side of the underframe and drive the upper or lower side of the underframe to be displaced in the horizontal direction are provided on each of the upper side and the lower side of the island frame. An attachment device for a pachinko gaming machine that is arranged is disclosed.

However, in the case of the devices disclosed therein, each unit not only has a complicated configuration and is time-consuming and costly to assemble, but also responds to the demand for easy and quick fine adjustment of the inclination of the pachinko machine. There is a problem that it cannot be done. In addition, there is a restriction that the control box for controlling each unit must be placed in the openable opening part at the top of the island where there is not enough space, and it is not easy to install. There's a problem.

Further, in Japanese Patent Application Laid-Open No. 2008-284280, a drive device is arranged in the central portion of the lower side of the island frame, and the drive device is a pachinko machine based on a detection angle signal from an angle detection device attached to the pachinko machine frame. An automatic installation angle adjusting device for a pachinko gaming machine that pushes and pulls the lower side of a frame to adjust the inclination of the pachinko underframe is disclosed. However, in the case of this device, since the lower side portion where the weight of the pachinko underframe is concentrated is pushed and pulled, a large pushing and pulling force is required, which causes a problem of inefficiency. Further, since the drive device and the lower side of the pachinko underframe are simply connected via the screw rod of the drive device, there is also a problem that a firm fixed state of the pachinko underframe cannot be ensured.

A mode for carrying out the present invention will be described with reference to the accompanying drawings. In the inclination adjustment system of the pachinko gaming machine according to the present invention, the tip portion is locked to the upper side of the pachinko underframe 41 housed in the island frame 51, and the pachinko underframe 41 moves forward and backward in the locked state. A pair of automatic adjustment units, which are provided with a clamp portion 5 for moving the upper side back and forth in the island frame 51 and are fixed to the island frame 51, are arranged on the left and right sides of the upper side of the pachinko underframe 41, and each automatic adjustment unit is remotely operated. The tilt angle of the pachinko underframe 41 can be adjusted to a preset angle, and the automatic adjustment unit can be remotely operated via a control board installed for each pachinko gaming machine. This is a feature (see FIGS. 1 and 7).

First, the configuration of the automatic adjustment unit in this system will be described (see FIGS. 1 to 6). The automatic adjustment unit in the illustrated example includes a gearbox 1 installed on the island frame 51, a stepping motor 2 attached to the gearbox 1, a screw clamp 3 protruding from the gearbox 1 so as to be able to advance and retreat, and a screw clamp 3. A clamp fixing plate 4 that is attached to the tip of the island frame 51 and is slidably supported on the top surface of the island frame 51, and a gear that is locked there by biting into the inner top surface of the upper side of the pachinko underframe 41. It has a stop head 6 and includes a toggle clamp device 5 installed on a clamp fixing plate 4. The gearbox 1 includes a projecting piece 1a, and the projecting piece 1a is fixed to the inner top surface end of the island frame 51 so that the gearbox 1 is installed on the island frame 51.

A gear set composed of a plurality of gears is deployed in the gearbox 1. The gear set in the illustrated example is arranged between the input gear 13 directly connected to the output shaft of the stepping motor 2, the drive gear 17 for driving the screw rod 3 forward and backward in the axial direction, and the input gear 13 and the drive gear 17. It is composed of three intermediate gears 14 to 16 (see FIGS. 2 and 3). The intermediate gears 14 to 16 are composite gears in which large-diameter and small-diameter gears are integrated.

The first intermediate gear 14 and the third intermediate gear 16 are pivotally supported by a common gear shaft 19 projecting from the inner wall of the gear box 1, and the second intermediate gear 15 is parallel to the gear shaft 19 of the gear box 1. It is pivotally supported by a gear shaft 20 projecting from the inner wall. Then, the input gear 13 meshes with the first intermediate gear 14, the first intermediate gear 14 meshes with the second intermediate gear 15, the second intermediate gear 15 meshes with the third intermediate gear 16, and the third intermediate gear 16 meshes with the third intermediate gear 16. Is meshed with the drive gear 17, and the number of teeth of each gear is set so that the rotation of the input gear 13 is gradually reduced and transmitted to the drive gear 17.

The screw rod 3 is a bar having a screw portion 3a in the middle, and one half thereof faces the inside of the gear box 1 and the other half is arranged in the gear box 1 so as to protrude from the gear box 1. The rear end of the screw rod 3 facing the inside of the gearbox 1 is pivotally supported by a bearing 22 installed on the side wall of the gearbox 1 so as to be rotatable and axially slidable. Further, a clamp fixing plate 4 for attaching the toggle clamp device 5 is attached to the tip of the screw rod 3 protruding from the gearbox 1.

The drive gear 17 has a female screw portion at the center thereof. Usually, the female screw portion is formed by fitting and fixing the hexagon nut 18 to the central portion of the drive gear 17 (see FIG. 4). The screw rod 3 is meshed with the drive gear 17 by screwing the screw portion 3a into the hexagon nut 18. As a result, when the drive gear 17 is rotationally driven via the gear set, the screw rod 3 in which the screw portion 3a is screwed into the female screw portion of the hexagon nut 18 is driven forward or backward in the axial direction thereof. become.

The clamp fixing plate 4 is inserted into a slide guide 21 fixed to the top surface of the island frame 51 and is slidably supported. The slide guide 21 is, for example, a metal fitting having an extended C-shaped cross section (see FIG. 5), and locks both sides of the clamp fixing plate 4 to support the horizontal movement of the slide guide 21.

The toggle clamp device 5 installed on the clamp fixing plate 4 is a fixing jig using a toggle mechanism, and in the present invention, a device having a general configuration composed of four-section links can be used. In the toggle clamp device 5 of the illustrated example, the base member 22 fixed to the clamp fixing plate 4, the clamp lever 23 attached to the base member 22, and the action arm that rotates in conjunction with the rotation operation of the clamp lever 23. The action arm 24 includes a locking head 6 at its tip, which is locked by biting into the inner top surface of the upper frame of the pachinko underframe 41 (see FIGS. 1 and 6).

In this configuration, the acting arm 24 is connected to the base member 22 at the fixed node A and to the clamp lever 23 at the node D. The clamp lever 23 is connected to the action arm 24 at the node D, and is also connected to the connecting member 26 attached to the fixed node B of the base member 22 at the node C. That is, the clauses A and B are fixed clauses, and the clauses B and C and the clauses C and D serve as a toggle mechanism, and the clause D operates in response to the input from the clause C.

In FIGS. 1 and 6, the locked state of the toggle clamp device 5 is shown by a solid line, and the unlocked state is shown by a virtual line. In the locked state shown by the solid line, the node C enters slightly inside the line connecting the nodes B and D, so that the locking head 6 bites into the locking head 6 through the node D with respect to the inner surface of the upper frame of the pachinko underframe 41. A force is generated and that state is maintained.

Then, when the clamp lever 23 is pulled down, the node C comes out of the line connecting the nodes B and D, so that there is no input from the node C to the node D, and the action arm 24 rotates counterclockwise. The locking head 6 is separated from the inner top surface of the upper frame of the pachinko underframe 41 (see virtual line). When the clamp lever 23 is pushed up from this unlocked state, it operates in the opposite direction to the above, and the locking head 6 bites into the inner top surface of the upper frame of the pachinko underframe 41 to enter the locked state, and that state is maintained.

In a preferred embodiment, a photointerruptor 31 for detecting the rotation angle of the drive gear 17 is incorporated in the gearbox 1, and the stepping motor 2 is controlled based on the rotation angle data of the drive gear 17 detected by the photointerruptor 31. By doing so, the inclination of the pachinko underframe 41 is adjusted. The photointerruptor 31 detects the rotation angle of the drive gear 17 by detecting the number of small holes 17a formed along the peripheral edge of the drive gear 17, and the amount of movement of the screw rod 3 is increased based on the rotation angle. Will be converted.

The relationship between the rotation speed of the stepping motor 2 and the inclination of the pachinko underframe 41 is stored as data in advance, and the rotation of the stepping motor 2 is controlled based on the data to control the rotation of the pachinko underframe 41. Adjust the degree of inclination. This data is used in the step control described later.

FIG. 7 is a schematic view showing the overall configuration of the inclination adjustment system according to the present invention. In this configuration, a control board 32 provided with a CPU 33 for controlling the operation of each stepping motor 2 is appropriately arranged at a location based on a signal from the photo interrupter 31 included in the automatic adjustment unit of each pachinko gaming machine. (In the example shown in FIG. 7, it is deployed in the call lamp 34). Then, as will be described later, each stepping motor 2 rotates by a predetermined amount, and the toggle clamp device 5 is driven forward and backward to move the pachinko underframe 41 back and forth, so that the degree of inclination can be automatically adjusted.

This inclination adjustment system is basically configured to be manageable for each pachinko gaming machine. For example, it is operated by operating a remote control 35 owned by an administrator, but is centralized in a computer 36 in a hall that manages the entire gaming facility. It can also be configured to be manageable. In that case, by operating the computer 36 in the hall in the management room, the main inclination adjustment system can be operated via the control board 32 of each pachinko gaming machine, and each pachinko can be operated. It is possible to perform batch tilt management and tilt adjustment of the gaming machine.

The pair of automatic adjustment units of each pachinko gaming machine may be configured to perform the same adjustment operation in synchronization with each other, but it is preferable that the pair of automatic adjustment units can be individually adjusted. In such a case, the twist of the pachinko underframe 41 can be adjusted by changing the amount of advance / retreat of the toggle clamp device 5 in each automatic adjustment unit.

The automatic adjustment unit of the inclination adjustment system according to the present invention having the above configuration is installed on the island frame 51 before the pachinko underframe 41 is fitted into the island frame 51. In that case, first, the slide guide 21 is placed on the inner surface of the island frame 51, and then the clamp lever 23 is pulled down to unlock (see the virtual lines in FIGS. 1 and 6). 4 is inserted from the lateral direction to the back inside the slide guide 21, and the gearbox 1 is fixed to the inner top surface of the island frame 51 (see the virtual lines of FIGS. 1 and 6 (A)). After that, the pachinko underframe 41 is fitted into the island frame 51 substantially vertically, the upper side thereof is brought close to the slide guide 21, and the lower side thereof is fixed to the inner bottom surface of the island frame 51 by means such as nailing or screwing. do.

When the clamp lever 23 is pushed up in this state, the locking head 6 turns upward, and the locking head 6 bites into the inner top surface of the upper frame of the pachinko underframe 41 to be in a locked state. When the stepping motor 2 is started by operating the remote controller 35 in that state, the gear set is rotationally driven, and the screw rod 3 meshing with the end drive gear 17 retracts to the right in FIG. 1 to fix the clamp. The toggle clamp device 5 fixed to the plate 4 is guided by the slide guide 21 and moves backward in the horizontal direction. Along with the movement, the upper frame of the pachinko underframe 41 locked by the locking head 6 is pulled, so that the inclination of the pachinko underframe 41 changes.

FIG. 8 shows a comparative display of a 1-degree tilt dimension value and a ○ minute ○ ㎘ in a pachinko underframe 41 having a height of 810 mm, and as shown there, is a case where the pachinko underframe 41 is tilted once. The dimension (movement amount of the upper end) is 4 minutes and 7 square meters (14.1 mm). Based on such data, in one embodiment, the control is performed in five stages of 3 minutes, 3 minutes, 5 square meters, 4 minutes, 4 minutes, 5 square meters, and 4 minutes, 7 square meters.

In order to enable such 5-step control, it is necessary to control the upper end of the pachinko underframe 41 so as to move by such a 5-step distance. For this control, the pachinko underframe 41 The rotation amount of the stepping motor 2 that determines the movement amount of the toggle clamp device 5 that moves integrally with the upper end portion of the above is set in 5 steps in advance, and can be selected by remote control operation or the like. By doing so, it is possible to efficiently and uniformly adjust the inclination. Then, when further fine-tuning is performed, it can be performed by a minute movement from any of the five steps of inclination.

Next, the second embodiment shown in FIG. 9 will be described. In the automatic adjustment unit of the second embodiment, a gear set including a plurality of gears is incorporated, and a gear box 1 installed on the island frame 51 and a gear set attached to the gear box 1 are rotationally driven. It is the same as the case of the first embodiment in that the stepping motor 2 is provided and the screw rod 3 which has a screw portion in the middle portion and is driven forward and backward in the axial direction by meshing with the gear set is provided. The gearbox 1 in this case differs from the first embodiment in that it is installed on the island frame 51 via the gearbox base 61.

The gearbox base 61 has a crank shape, the first half of which is attached to the inner top surface of the island frame 51, and the connecting plate 62 extending horizontally from the gearbox 1 is fixed to the second half of the base, whereby the gearbox 1 is formed. It is fixed to the island frame 51. A slide guide 63 is installed on the back surface of the connecting plate 62, and the slide guide 63 slidably supports the slide plate 64 attached to the tip of the screw rod 3. For example, the slide guide 63 shall have a pair of grooves extending in the horizontal direction, and a wing portion engaging with the grooves shall be provided on the upper side of the slide plate 64.

The slide plate 64 is connected to an action portion whose tip end portion is fixed to the inner top surface of the pachinko underframe 41 via a bracket 65 installed at the bottom portion thereof. The working portion is composed of a locking plate 67 connected to the bracket 65 and a fixing plate 69 extending in the horizontal direction from the locking plate 67, and a vertically elongated hole 68 is provided in the locking plate 67, and the bracket is provided therein. A locking pin 66 laterally arranged at the tip of the 65 is slidably engaged. The working portion is fixed to the pachinko underframe 41 by fastening the fixing plate 69 to the cut portion 42 on the inner top surface of the pachinko underframe 41.

The configuration of the gear assembly in the gearbox 1 is basically the same as that of the first embodiment, but in the example shown in FIG. 9, the photo interrupter 31 is not the drive gear 17 itself, but the drive gear 17. It is configured to detect the rotation angle of the connecting flange 70 provided on the barrel integrated with the shaft.

In the case of the second embodiment, the screw rod 3 moves forward and backward by operating the stepping motor 2, and the slide plate 64 and the bracket 65 are supported by the slide guide 63 and move forward and backward in the horizontal direction. The movement of the bracket 65 is transmitted to the locking plate 67 via the locking pin 66 at the tip thereof, and the locking plate 67 is pushed and pulled in the horizontal direction, but the locking pin 66 engages with the vertically elongated hole 68. Due to the matching relationship, the pachinko underframe 41 can be pushed and pulled in an arc shape with the base as the axis, and the degree of inclination thereof can be adjusted. The above other points are the same as in the case of the first embodiment.

In the case of this second embodiment, since the fixing plate 69 of the working portion is fastened to the inner top surface of the pachinko underframe 41 by screwing or the like, the fixed state with respect to the pachinko underframe 41 becomes stronger. Further, since the slide guide 63 is installed on the island frame 51 not directly but via the gearbox base 61, even if the thickness of the upper part of the pachinko underframe 41 varies (uniformly depending on the manufacturer). No), it will be possible to respond without problems.

The third embodiment shown in FIG. 10 is a modification of the example shown in FIG. 9, and in the fixing plate 69 in that case, the tip surface of the load screw 71 screwed from the back surface side is the inner top surface of the pachinko underframe 41. By applying a strong pressure and applying a load, the pachinko machine frame 41 is fixed to the inner top surface. Further, the example shown in FIG. 11 is a modified example of the third embodiment shown in FIG. 10, and is an upper surface of the locking plate 67 so that the inner top surface of the pachinko underframe 41 can be pressed more stably and reliably. The auxiliary plate 72 is fixed to the pachinko machine, and the auxiliary plate 72 is brought into contact with the top surface of the pachinko machine frame 41 so as to sandwich the end portion of the pachinko machine frame 41.

In the fourth embodiment shown in FIG. 12, the clamp members 73 and 74 extending forward from the locking plate 67 are fixed to the pachinko underframe by sandwiching the end of the pachinko underframe 41. be. The clamp members 73 and 74 come into contact with the top surface of the pachinko underframe 41 by tightening the tightening screws 75 straddling the two, and the clamp member 73 comes into contact with the inner top surface of the pachinko underframe 41. By being attracted to the 74, the end portion of the pachinko underframe 41 is strongly clamped by the clamp members 73 and 74.

In this case, if necessary, in addition to the tightening screw 75, a gripping pin 76 that penetrates the end of the pachinko underframe 41 and connects the clamp members 73 and 74 is arranged.

The inclination adjustment system according to the present invention has a simple configuration in any of the above embodiments, can be easily installed without taking up space, and finely and uniformly adjusts the inclination by remote control operation or the like. It becomes possible. Further, not only can each pachinko machine be individually managed by remote control operation or the like, but also batch tilt management and tilt adjustment can be performed by a computer in the hall, which has great industrial applicability.
