Description

  The present invention relates to a pachinko ball conveying device on amusement islands.

  On the amusement island where a number of pachinko machines are lined up side by side, a ball polisher is installed in the center, and the pachinko balls polished by the ball polisher are placed in the upper tank installed at the top. It was stored and supplied to each pachinko machine or ball lending machine through a replenishment rod inclined from the upper tank to the end of the amusement island.

In order to attach the slanted and extended supply rod to the upper part of the game island, a predetermined inclination angle must be ensured. For this reason, the upper tank side end portion of the replenishment rod is 30 to more than the other end on the end side. It had to be as high as 50 cm.
As a result, the height of the cover plate that hides the replenishment basket (conveyance device) in the upper part of the pachinko machine is increased, and the height of the entire island gives the player a feeling of pressure.

For this reason, there is a conveying device disclosed in, for example, Japanese Patent Application Laid-Open No. 6-39146, which can suppress the height of the replenishing rod (conveying device) and reduce the height of the cover plate.
This is because the conveyor belt is arranged in the horizontal direction along the pachinko machine row, and it is not necessary to incline and raise one end like a conventional replenishment basket, so that the height of the game island can be kept low. it can.
As another example, Japanese Patent Application Laid-Open No. 2004-275670 discloses a horizontal conveyance device in which a plurality of rotating disks are arranged adjacent to each other along a pachinko machine row. In this method, pachinko balls are transferred and conveyed between adjacent rotating disks rotated in opposite directions.
JP-A-6-39146 JP 2004-275670 A

However, since the thing of Unexamined-Japanese-Patent No. 6-39146 is a conveyor structure which arrange | positioned the roller at both ends and wound the belt between the rollers, the operation | work set up on the upper part of a game island is troublesome and takes time, There is a possibility that the belt may be cut, stretched or slipped, and there is a need for on-site adjustment and repair in the pachinko parlor.
Moreover, in the thing of Unexamined-Japanese-Patent No. 2004-275670, when the pachinko balls are clogged in the middle of conveyance, the rotating disk cannot be rotated, so the pachinko balls cannot be smoothly fed to the end, and more Since it is necessary to install the rotating disks side by side, there is a problem that the construction takes time and the cost is inevitably high.

  Therefore, in view of the above-mentioned conventional problems, an object of the present invention is to provide a pachinko ball transport apparatus that can reduce the height of the entire game island and can be realized at a low cost with a simple configuration.

  For this reason, the pachinko ball conveying apparatus according to the present invention arranges unit replenishing rods of a predetermined length in the pachinko machine row direction, and the unit replenishing rods can swing from a horizontal posture between two side walls. And a drive mechanism for oscillating the unit wall plate, the adjacent unit wall plates are sequentially swung, and the unit wall plate in an adjacent horizontal posture from the unit wall plate inclined by the swinging. It was assumed that the movement of the pachinko balls was repeated in sequence.

  The transport path for supplying pachinko balls to the end of the pachinko machine is divided into a plurality of unit replenishment rods, and the pachinko balls are moved by swinging the unit plate in the unit replenishment rods. Can take a sufficient inclination within a limited height range, and the height of the entire conveying apparatus can be reduced with a simple configuration.

Each unit replenishing rod 10 has a length corresponding to the width of one pachinko machine and the width of the ball lending machine attached thereto, that is, the interval between the pachinko machines.
The unit supply basket 10 is supported by a frame 60 installed on the pachinko machine array.

Each unit replenishing rod 10 has a plurality of unit rods 20 (20a to 20d) having a width matching the interval between the side walls 11 and 11 arranged in parallel with a rectangular basic shape on the side surface. As a whole, the cross section is H-shaped.
Here, the upstream side when the pachinko balls are conveyed, that is, the upper tank 5 side is the front, and the downstream side is the rear.
In addition, although the two side walls 11 and 11 arrange | positioned in parallel are right and left object, it shows with the same number for simplicity.

The frame 60 includes two vertical members 61 arranged in parallel and a cross member 62 that is provided at the same interval as the interval between the pachinko machines arranged horizontally along the vertical member and connects the vertical members 61.
At both front and rear ends of the unit replenishment rod 10, flanges 12 to be described later of the side wall 11 are placed on the cross member 62, and the flange portion is fixed to the cross member 62 with bolts or the like. The unit supply rods 10 adjacent to the front and rear are arranged in the longitudinal direction on the cross member 62 with the edges of the side walls 11 abutting each other.

2 is a perspective view of the unit replenishing rod 10, FIG. 3 is an enlarged view of the longitudinal section of the unit replenishing rod 10, and FIG. 4 is an enlarged view taken along the line AA in FIG.
Both side walls 11 are provided with flanges 12 at the lower edges thereof, extending in opposite directions and extending in the front-rear direction.
On the downstream side of the side walls 11, ball supply ports 14 that are cut out in a rectangular shape from the upper edge are provided. Storage boxes (not shown) are provided on both sides in the width direction across each unit replenishment rod 10 so as to correspond to the ball supply ports 14 respectively.
The pachinko balls that have flowed from the unit replenishment basket 10 to the storage box through the ball supply port 14 once stay in the storage box, and then are supplied to a pachinko machine (not shown) and a ball lending machine located below.

A hinge pin 17 is provided between the side walls 11 of the unit replenishing rod 10 so as to maintain a mutual space. Although not shown in particular, the hinge pin 17 has screw portions at both ends, and the screw portions are inserted into pin holes provided at regular intervals in the front-rear direction at a substantially intermediate position in the height direction of the side wall 11 and tightened with nuts 19 from the outside. As a result, it is fixed to the side wall 11.
Alternatively, as a small shaft having a ring groove instead of the threaded portion, the snap ring can be fitted into the ring groove after passing through the pin hole.

The unit gutter plate 20 has a U-shape having horizontal flanges 22 extending downward from both lateral ends of the main wall 21 having a flat surface and having a horizontal section opened downward.
The front end of the main wall 21 is bent downward to form a front flange 23 having the same width (height) as the lateral flange 22. Further, a pin receiving portion 25 that receives the hinge pin 17 by being cut out in a U shape is formed at the rear end of the lateral flange 22.
The side walls 11 are provided with stopper pins 13 protruding toward the space between the side walls 11 at regular intervals in the front-rear direction, receiving the lower edge of the lateral flange 22 in the vicinity of the front end of each unit wall plate 20, The unit gutter plate 20 in which the rear end pin receiving portion 25 is engaged with the hinge pin 17 is held in a horizontal posture.

  As shown below, the unit saddle plate 20 can swing upward from the horizontal posture with the hinge pin 17 as a fulcrum, that is, with the rear end portion as a fulcrum as the unit saddle plate. A minute predetermined gap is set between the adjacent unit ribs so that when one of them swings around the hinge pin 17, its front end (front flange 23) does not interfere with the other rear end.

A cam support shaft 30 is disposed under the unit flange 20 over substantially the entire length of the side wall 11.
The cam support shaft 30 is supported by inserting its shaft end into an attachment 47 of the bearing 40.
The bearing 40 is supported by a bearing support bracket 50 attached to the upper surface of the flange 12 of each side wall 11 in a space between the side walls 11 at the rear part of the unit replenishing rod 10.
Below the bearing 40, a motor 53 is supported by a motor support bracket 52 attached to the lower surface of the flange 12 of the side walls 11.
A pulley 55 is attached to the output shaft 54 of the motor 53, and a belt 56 is hung between the pulley 55 and the pulley 43 of the bearing 40.

FIG. 5 is a perspective view showing the cam support shaft 30 and its drive system.
The cam support shaft 30 is provided with cam rollers 33 at regular intervals in the longitudinal direction thereof, and is set to be engageable with the lower edge of each front flange 23 of the unit flange plates 20a to 20d whose rear ends are supported by the hinge pins 17. . The cam support shaft 30 has a square cross section, and the adjacent cam rollers 33 are supported by brackets 32 fixed to the back-to-back surfaces of the cam support shaft 30 and are sequentially shifted by 180 ° in the direction around the cam support shaft 30. Yes. The rotation axis of the cam roller 33 is parallel to the cam support shaft 30.
FIG. 5 shows only the main part.

FIG. 6 shows details of the bearing 40.
The bearing 40 (the same subscript as that of the unit supply rod is used to distinguish between the unit supply rods) includes an outer race 41 fixed to the bearing support bracket 50 and an inner race 42 that is rotatable with respect to the outer race 41. Have.
The inner race 42 includes a pulley 43 on the rear side, and an attachment receiving portion 44 is formed on the rear end surface of the pulley 43. The attachment receiving portion 44 is a concave portion in which the planar shape centering on the axial center of the inner race 42 is a polygonal shape such as four strokes when viewed from the axial direction. The attachment receiving portion 44 includes a female screw 45 formed on the bottom wall (that is, the bottom wall of the recess) so as to coincide with the axis.

An attachment receiving portion 46 is also formed on the front end surface of the inner race 42. The shape of the attachment receiving portion 46 is the same as that of the attachment receiving portion 44, and is set so that the planar shapes of both attachment receiving portions 44 and 46 are aligned and overlap each other when seen through from the axial direction.
The attachment 47 is attached to the attachment receiving portions 44 and 46 by fitting the matching protrusions. The attachment 47 includes a support hole 48 having a shape matching the end shape (square section) of the cam support shaft 30 on the side opposite to the protrusion, and the bolt 49 is attached to the attachment receiving portion through a hole provided in the bottom wall of the support hole 48. The inner race 42 is integrated by screwing into the female threads 45 on the bottom walls 44 and 46.

One end (rear end) of the cam support shaft 30 is inserted into the support hole 48 of the front attachment 47 in the bearing 40B of the unit supply rod 10B, for example, and the other end (front end) of the cam support shaft 30 corresponds to the front side. It is inserted into the support hole 48 of the attachment 47 on the rear side (pulley side) of the bearing 40A of the adjacent unit supply rod 10A and supported.
The front end of the cam support shaft 30 of the unit replenishing rod 10A that is directly connected to the upper tank 5 is also supported by being inserted into an attachment (47) that is rotatably provided in the upper tank 5, although not particularly shown.
Further, in the unit replenishment rod 10 corresponding to the pachinko machine on the island edge of the amusement island, the attachment 47 of the pulley 43 is unnecessary and may be removed.

In addition, since the pulleys 43 and 55 and the belt 56 in the adjacent unit replenishing rod 10 are set at positions away from the edge of the side wall 11 while avoiding the cross member 62, the cam support shaft inserted into the attachment 47 of the pulley 43. The front end of 30 projects and extends into the adjacent unit supply rod 10.
Further, in the drawing, the front end of the frontmost unit wall 20a of the unit replenishing rod 10 also protrudes into the adjacent unit replenishing rod 10, but depending on the setting position of the hinge pin 17 that supports the unit wall 20, By making the front end substantially coincide with the front end of the side wall 11, it can be prevented from protruding.

With the above configuration, when the motor 53 is driven, the rotation is transmitted to the inner race 42 of the bearing 40 via the belt 56, and the attachment 47 rotates together with the inner race 42 to rotate the cam support shaft 30.
The cam support shaft 30 including the cam roller 33 is rotationally driven by a motor 53 via a belt 56 and a pulley 43, and the unit roller plates 20a to 20d are alternately swung by the cam roller 33 to form a drive mechanism in the invention. ing.

  Along with the rotation of the cam support shaft 30, the cam roller 33 pushes up the front end of the unit collar plate 20, and the unit collar plate 20 swings with the hinge pin 17 at the rear end as a fulcrum. Each unit plate 20 swings alternately with the unit plate 20 adjacent to the front and back. For example, while one unit plate 20b swings one reciprocating motion, the unit plate 20a or 20c adjacent to the unit plate 20b. The front part is supported by the stopper pin 13 to maintain the horizontal state.

Since the front end of the unit base plate 20 swings with the rear end hinge pin 17 as a fulcrum, the pachinko balls supplied on the unit base plate 20a when the upstream unit base plate 20a is in a horizontal state are Next, when the front end of the unit wall 20a is lifted and tilted, the adjacent unit wall 20b is in a horizontal state, and therefore rolls on the unit wall 20a and moves onto the unit wall 20b.
At this time, since the unit end plate 20c adjacent to the downstream side of the unit end plate 20b is lifted at the front end in the same manner as the unit end plate 20a, the pachinko balls flowing from the unit end plate 20a to the unit end plate 20b are all at once. Without moving to the unit plate 20c, it is held on the unit plate 20b.

Then, when the cam support shaft 30 further rotates and the unit flange 20b swings and tilts, the unit flange 20c is in a horizontal state in conjunction with it, so that the pachinko balls held on the unit flange 20b are , It moves onto the unit plate 20c.
The above operation is sequentially repeated between the unit wall plates 20a to 20d, and the pachinko balls are conveyed from the upstream side to the downstream side in the unit replenishment rod 10.
A part of the pachinko balls conveyed to the unit saddle plate 20d flows from the ball supply port 14 provided on the side wall 11 to the storage box and is supplied to the corresponding pachinko machine.

The conveying apparatus 1 is configured by sequentially connecting a plurality of unit supply rods 10 having the above structure. When the front end of the cam support shaft 30 is inserted into the attachment 47 of the pulley 43 of the adjacent unit replenishment rod, the adjacent cam roller 33 between the cam support shafts 30 and 30 connected via the attachments 47 and 47 is rotated around the axis. The direction is shifted by 180 °.
As a result, the unit wall plates 20d and 20a adjacent to each other across the connecting portion of the unit replenishing rod also swing alternately as in the single unit replenishing rod 10; The pachinko balls can be smoothly transported from the upper tank 5 of the game island to the pachinko machine on the island edge while being appropriately supplied from each ball supply port 14.

The embodiment is configured as described above, and unit supply rods 10 (10A, 10B,...) Having a length corresponding to the interval between the pachinko machines are arranged in the direction of the pachinko machine row, 11 and 11, each of which is provided with a drive mechanism for swinging the unit support plate, and the adjacent unit support plates are sequentially swung, Since the pachinko balls are sequentially moved from the unit plate inclined by swinging to the adjacent unit plate in the horizontal posture, even if the unit plate 20 having a short length is inclined as much as necessary, The slope height can be low. Accordingly, the height of the unit replenishing rod may be lower than that of the one replenishing trough extended to the end of the pachinko machine row, so that the overall height of the transport device can be reduced.
Since the unit replenishment rod 10 having a simple structure is used, there is no need for adjustment work and problems of deterioration as compared with those using a conveyor configuration or a rotating disk, and the cost can be kept low.
Moreover, since the pachinko ball moves by its own weight using the inclination of the unit base plate 20, there is no idling and a reliable transport operation is obtained, and there is a concern about biting even when the unit base plate 20 is full of pachinko balls. Nor.

  The unit flange 20 includes a horizontal flange 22 parallel to the side wall 11, and a pin receiving portion 25 formed by notching the downstream end portion of the horizontal flange is engaged with a hinge pin 17 provided on the side wall 11 to swing. A motor 53 is provided with a cam support shaft 30 including a cam roller 33 that can be used as a fulcrum and the drive mechanism extends along the unit plate 20 and can alternately push up the lower edge of the front flange 23 that is the upstream end of the unit plate. Since it is driven to rotate, the structure is simple, and even when the unit replenishment rod 10 is fixed to the frame 60, the unit wall plate 20 is detachable, and maintenance and replacement are easy.

  The length of the unit replenishment basket 10 is made to correspond to the interval between the pachinko machines, and further, a ball supply port 14 for supplying pachinko balls from the unit wall board 20 to the pachinko machine is provided on the downstream side of the side wall 11. It is sufficient to install according to the number of pachinko machines, and when pachinko machines are added, they can be added according to the number of pachinko machines.

Next, FIG. 7 shows a modification of the unit supply basket.
The unit supply rod 10 ′ has a side wall 70 instead of the side wall 11. The side walls 70 and 70 sandwiching the unit wall 20 are symmetrical, but are indicated by the same number for simplicity.
Similar to the side wall 11, the side wall 70 includes a first wall 71 that spans the hinge pin 17, a third wall 73 that is offset from the first wall 71 to the left and right outwards and rises in parallel with the first wall 71, and a first wall The second wall 72 connects the 71 and the third wall 73.
A ball supply port 14 is provided on the downstream side of the third wall 73.
The second wall 72 is linearly inclined so as to increase from the position of the front (upstream side) edge of the ball supply port 14 to the front end, and swings at the front end to swing to the maximum inclination. It is higher than the height of the front end of 20a.

The second wall 72 is bent at a right angle to the first wall 71 and is horizontal in the left-right direction.
The second wall 72 does not incline from the position of the front edge of the ball supply port 14 toward the rear end, and the upper edge of the first wall 71 coincides with the height of the unit wall plate 20d in the horizontal posture. However, the second wall 72 from the position of the front side edge of the ball supply port 14 to the rear end direction becomes an outward inclined portion 74 inclined downward to the height of the lower edge of the ball supply port 14 toward the left and right outwards. ing.
The front end of the second wall 72 is bent downward to form a stopper wall 75 that is lowered to the height position of the outwardly inclined portion 74 of the second wall in the adjacent unit replenishing rod 10 '.
Other configurations are the same as those of the first embodiment.

According to this modification, in addition to the effects of the first embodiment, the following effects can be further obtained.
That is, the pachinko balls that have flowed in from the adjacent unit replenishment baskets are provided with the second walls 72 on the left and right sides of the unit board 20, so that some of the pachinko balls from the upstream unit board 20a, 20b, etc. Spill onto the second wall 72. Since the second wall 72 is inclined downward toward the downstream side, the pachinko balls spilled onto the second wall 72 roll by bypassing the unit wall plates 20c and 20d and quickly reach the downstream end. The pachinko ball that has reached the outer inclined portion 74 at the downstream end is stopped by a stopper wall 75 that descends from the front end of the second wall of the unit supply rod adjacent to the downstream side, and the outer inclined portion 74 faces the ball supply port 14. Therefore, the ball is efficiently guided to the ball supply port 14 and supplied to a pachinko machine or the like corresponding to the unit supply basket.

Next, a second embodiment will be described.
This is because the unit reed plate is swung every other unit reed plate while every adjacent unit reed plate is swung every other unit reed plate in the first embodiment. It is what.
FIG. 8 is a perspective view showing a cam support shaft and its drive system corresponding to FIG. FIG. 9 is a longitudinal sectional view showing the structure of the unit replenishing rod corresponding to FIG.
The cam support shaft 30A in the unit replenishing rod 100 is supported by inserting its shaft end into the attachment 47A of the bearing 40.
Cam rollers 33 are attached to the cam support shaft 30A at regular intervals so as to be engageable with the lower edges of the front flanges 23 of the unit flange plates 20a to 20d, whose rear ends are supported by the hinge pins 17.

The cam support shaft 30A has a regular hexagonal cross section, and the adjacent cam rollers 33 are supported by brackets 32 that are sequentially fixed to every other adjacent surface of the cam support shaft 30 so that the cam support shaft 30A is rotated around the axis of the cam support shaft 30A. The direction is shifted by 120 °. The rotating shaft of the cam roller 33 is parallel to the cam support shaft 30A.
Although the attachment 47A is not shown in the drawing, the end shape (cross section) of the cam support shaft 30A is used instead of the support hole 48 on the side opposite to the protrusions aligned with the attachment receiving portions 44 and 46 (see FIG. 6) of the bearing 40. A support hole having a shape matching a regular hexagon) is provided.
The other configuration of the unit supply rod 100 is the same as that of the unit supply rod 10 in the first embodiment.

  When the plurality of unit replenishing rods 100 are sequentially connected to constitute the conveying apparatus 1A, the front end of the cam support shaft 30A is inserted into the attachment 47A of the pulley 43 of the upstream adjacent unit replenishing rod through the attachments 47A and 47A. The adjacent cam rollers 33 between the connected cam support shafts 30A and 30A are displaced by 120 ° in the same direction around the shaft.

FIG. 10 shows a swinging mode of the unit wall plate in the above-described configuration.
Along with the rotation of the cam support shaft 30A, the cam roller 33 pushes up the front end of the unit collar plate 20, and the unit collar plate 20 swings around the hinge pin 17 at the rear end. The cam support shaft 30A rotates in the direction indicated by the arrow R in FIG.
For example, as shown in FIG. 10 (a), while the unit wall 20b of the unit replenishing wall 100B swings one reciprocating motion, the unit wall 20a adjacent to the upstream side and the unit wall 20c continuing to the downstream side. And 20d, the front part is supported by the stopper pin 13 (see FIG. 9), and the horizontal state is maintained. In the unit supply rod 100A, the unit plate 20d adjacent to the horizontal unit plate 20a of the unit supply plate 100B is in a horizontal state, and the unit plate 20c is synchronized with the unit plate 20b of the unit supply plate 100B. While swinging, the unit ribs 20b and 20a following the upstream side maintain the horizontal state.

  When the rotation of the cam support shaft 30A advances by 120 ° from the state of FIG. 10 (a), the state changes to the state of (b). Here, in the unit supply rod 100B, the unit rod plates 20a and 20d are swung and inclined, and the unit rod plates 20b and 20c are in a horizontal state. In the unit supply rod 100A, the unit rod 20b is inclined, and the unit rods 20a, 20c, and 20d are in a horizontal state.

When the cam support shaft 30A further rotates by 120 °, the state changes to the state (c). That is, in the unit replenishment rod 100B, the unit collar plate 20c is inclined and the unit collar plates 20a, 20b, and 20d are in a horizontal state. In the unit supply rod 100A, the unit flange plates 20a and 20d are swung and inclined in synchronization with the unit flange plate 20c of the unit supply rod 100B, and the unit flange plates 20b and 20c are maintained in a horizontal state.
Thus, in the conveying apparatus 1A configured by sequentially connecting the unit replenishing rods 100, the unit plate 20 is moved downstream one by one while sequentially moving the swing timing of the unit plate 20 between adjacent unit plates. The unit wall plate swings so that the two unit wall plates adjacent to the side are in a horizontal state.

When the unit wall 20 swings and tilts, the pachinko balls on the unit wall 20 roll and move toward the unit wall 20 adjacent to the downstream side. Even if the plate 20 finishes swinging and returns to the horizontal state, it continues to roll with inertia.
According to the present embodiment, for example, when changing from (a) to (b) in FIG. 10, the unit wall plate 20c adjacent to the downstream side of the unit wall plate 20b returned to the horizontal state in the unit supply wall 100B is also horizontal. Since it is in the state, the advantage that the pachinko balls rolling on the unit base plate 20b with inertia can continue to move to the unit base plate 20c without being obstructed as compared with the first embodiment. Have
In addition, when the rotational speeds of the cam support shafts 30 and 30A are the same, the number of unit ribs 20 that are inclined at the same time, that is, the frequency with which the unit ribs are swung is reduced, so the motor load is also reduced. .

Next, a third embodiment will be described.
In this case, every third unit plate is swung.
FIG. 11 is a perspective view showing the cam support shaft and its drive system corresponding to FIG. FIG. 12 is a longitudinal sectional view showing the configuration of the unit replenishing rod corresponding to FIG.
The cam support shaft 30 in the unit replenishing rod 110 has the same square cross section as that in the first embodiment, and the shaft end is inserted into and supported by the attachment 47 of the bearing 40.
Cam rollers 33 are attached to the cam support shaft 30 at regular intervals so as to be able to engage with the lower edges of the front flanges 23 of the unit flange plates 20a to 20d whose rear ends are supported by the hinge pins 17. The cam roller 33 is supported by brackets 32 that are sequentially fixed to adjacent surfaces of the cam support shaft 30, and is shifted by 90 ° in the direction around the cam support shaft 30. The rotation axis of the cam roller 33 is parallel to the cam support shaft 30.
The other configuration of the unit supply rod 110 is the same as that of the unit supply rod 10 in the first embodiment.

  When the transport device 1B is configured by sequentially connecting a plurality of unit supply rods 110, when inserting the front end of the cam support shaft 30 into the attachment 47 of the pulley 43 of the upstream adjacent unit supply rod, the attachment 47, 47 is used. The adjacent cam rollers 33 between the connected cam support shafts 30 and 30 are shifted by 90 ° in the same direction around the shaft.

FIG. 13 shows a swinging mode of the unit wall plate in the above-described configuration.
Along with the rotation of the cam support shaft 30, the cam roller 33 pushes up the front end of the unit collar plate 20, and the unit collar plate 20 swings with the hinge pin 17 at the rear end as a fulcrum.
For example, as shown in (a), while the unit wall plate 20a of the unit replenishment rod 110B swings one reciprocating motion, the unit wall plates 20b, 20c, and 20d that are sequentially adjacent to the downstream side of the unit wall plate 20a have stoppers as front portions. 13 (see FIG. 12) is maintained in a horizontal state. In the unit supply rod 110A, the unit plate 20d, 20c and 20b adjacent to the swinging unit plate 20a of the unit supply plate 110B are horizontal, and the unit plate 20a is the unit plate 20a of the unit supply plate 110B. Swing in sync with.

  When the rotation of the cam support shaft 30 advances by 90 ° in the direction indicated by the arrow R in FIG. 11 from the state of FIG. 13 (a), the state changes to the state of (b). Here, in the unit supply rod 110B, the unit rod 20d swings and tilts, and the unit rods 20c, 20b, and 20a that successively follow the upstream side thereof are in a horizontal state. Also in the unit replenishment rod 110A, the unit ribs 20d are inclined, and the unit ribs 20c, 20b, and 20a are in a horizontal state.

When the cam support shaft 30 is further rotated by 90 °, the state changes to the state (c). That is, in the unit supply rod 110B, the unit rod 20c is inclined and the unit rods 20a, 20b, and 20d are in a horizontal state. In the unit supply rod 110A, the unit flange plate 20c swings and tilts in synchronization with the unit flange plate 20c of the unit supply rod 110B, and the unit flange plates 20a, 20b, and 20d maintain the horizontal state.
Thus, in the conveying apparatus 1B configured by sequentially connecting the unit replenishment rods 110, the unit plate 20 is moved downstream one by one while sequentially moving the swing timing of the unit plate 20 between adjacent unit plates. The unit plate is swung so that the three unit plates adjacent to the side are in a horizontal state.

  Also according to the present embodiment, the unit wall plate adjacent to the downstream side of the unit wall plate 20 that has returned to the horizontal state from the swinging state is also in the horizontal state. Therefore, as in the second embodiment, it has just returned to the horizontal state. The pachinko balls that roll on the unit base plate with inertia can continue to move to the unit base plate on the downstream side without being obstructed, and the motor load is also reduced.

In each of the embodiments and modifications, the length of the unit replenishment basket 10 is made to correspond to the interval between the pachinko machines, but the present invention is not limited to this. The length can be set arbitrarily.
Further, each unit replenishment rod 10 is provided with a motor 53 as a power source of the drive mechanism, but the cam support shafts 30 of adjacent unit replenishment rods are connected to each other via an attachment 47 of the bearing 40. One motor may be set for a plurality of unit supply rods.

Although an example in which four unit support plates 20 are provided for one unit supply rod has been shown, the number of unit support plates can be appropriately set according to the length of the unit supply plate or the like.
In addition, the rotation of the cam support shaft 30 by the motor 53 is performed via the pulleys 55 and 43 and the belt 56, but may be performed via a gear.
The cam support shaft 30 is provided with a cam roller 33 that pushes up the lower edge of the front flange 23 of the unit wall plate in order to swing the plurality of unit wall plates 20 alternately. Instead, the main wall of the unit wall plate It is also possible to use an eccentric cam that is in sliding contact with 21 or the front flange 23.

  In each embodiment and modification, the hinge pin 17 that supports the unit flange plate 20 is stretched between the side walls 11 and the stopper pin 13 protrudes from the side wall as much as necessary. However, the present invention is not limited to this. The stopper pin 13 may be stretched between the side walls 11 or the hinge pin 17 may be protruded from the side wall by a necessary minimum.

Although the unit flange 20 extends the horizontal flange 22 downward from both lateral ends of the main wall 21, the unit flange may be formed into a hook shape by itself. In this case, a part on the downstream side of the lateral flange is cut out to be a communication port to the ball supply port 14.
Furthermore, although the main wall 21 of the unit roof 20 is a flat surface, it can also have a cross-sectional roof shape with the left and right width centers as apexes and inclined sides on both sides. Can be guided to the ball supply port 14 or smoothly to the second wall 72 in the modified example.

  Moreover, although each Example and the modification showed about the example applied to the game island formed by making two pachinko machine rows back to back, the present invention can of course be applied to a game island of only one side.
