Description

[Detailed description of the invention] The present invention relates to an article transfer mechanism of a conveying device, and more specifically, coins sent from a pachinko ball rental machine, a vending machine, etc. via a belt conveyor are transferred into a bucket while the bucket conveyor is moving. Concerning the transfer mechanism for transshipment.

Traditionally, at pachinko halls, coins inserted into numerous ball lending machines installed between pachinko machines are collected on a common belt conveyor into a tray at the end of the island, and workers go around each island to collect the coins. This required manpower and was inefficient.

Recently, the coins sent from the island conveyor are sent to a predetermined position by a belt conveyor device installed under the floor, and from there they are transferred to the bucket of a bucket conveyor lift, lifted to a high place, and automatically collected at a predetermined position by a chute. A device is being developed.

However, as mentioned above, there are generally various difficulties in transferring the articles that are continuously sent into a moving bucket cart. In other words, items such as coins randomly fall into the buckets that are continuously transported, so sometimes the items fall into the gaps between the buckets and do not enter the buckets, or they are transported while being sandwiched between the buckets. There were problems such as preventing smooth operation of the conveyor lift.

An object of the present invention is to solve these problems and provide a transfer mechanism that can reliably accommodate articles sent from a conveyor or the like into a moving bucket.

Hereinafter, one embodiment of the present invention will be described based on the drawings. Although the present invention is generally applicable to conveyance devices for small articles, the figure shows an example of application to a coin collection device for a pachinko ball rental machine.

In the figure, 1 is a coin supply port connected to an end of a belt conveyor (not shown). Facing below the supply port 1 is a bucket conveyor type conveyor means 6 which is suspended between a pair of sprockets 2a and 2b and has a large number of buckets 5 connected to an endless chain 4 that rotates along a guide rail 3. The coins 7 falling from the supply port 1 are received in a bucket 5 of the conveying means 6 and sent to a predetermined position.

In such a conveying device, the feature of the present invention is that a pair of gears 10a and 10b are meshed and rotatably attached to the frame 9 that constitutes the falling passage 8 of the supply port 1, and one gear 10a has a frame 9 that constitutes the falling passage 8. The upper part of the swinging guide plate 11 facing downwardly inclined is connected to the other gear 10b, and the upper part of the swinging arm 12 hanging down to the side of the bucket transport path is rotatably connected to the corresponding gear. In addition, a bracket 17 is integrally attached to the conveying means 6 in correspondence with each bucket 5 by intermittently engaging with the tip of the swinging arm 12 to operate the arm 12 in a pendulum shape. .

That is, as shown in FIGS. 1 and 2, the gear 1
0a and 10b are supported by the frame 9 of the passage 8 in a vertically engaged manner so that they can cooperate and rotate in opposite directions.

The gears 10a and 10b are integrated into a rotating shaft 10 that extends in the width direction of the drop passage 8 and is pivotally supported by the frame 9 on the opposite side.
a', 10b', and the rotating shaft 10 of the upper gear 10a.
At a', a swing guide plate 11 extending in the width direction of the passage 8 is arranged in a downwardly inclined manner with respect to the traveling direction of the bucket and is fixed integrally with a mounting bracket or a welding valve. A swing arm 12 is integrally fixed to the other end of the rotating shaft 10b'. The swing plate 11 and the swing arm 12 are connected to the arm 1 as shown in the figure.
2 hangs vertically and its tip protrudes into the conveyance path 6', the tip of the rocking plate 11 rotates to near the center of the passage 8, closing the rear passage 8a and simultaneously guiding it to the front passage 8b. Set each position so that it forms a board. Thus, when the arm 12 rotates counterclockwise, the swing plate 11 rotates clockwise in cooperation with the arm 12, thereby opening the rear passage 8a.

Incidentally, the operating ratio of the rotation angle between the arm 12 and the swing plate 11 can be adjusted by the diameters of the corresponding gears 10a, 10b. In the example shown, the rocking plate 11
The diameter of the gear 10a is made smaller than that of the gear 10b so that the rotation angle and speed of the arm 12 are larger than those of the arm 12.

Although the arm 12 can be returned to the hanging position by its own weight, it is preferable to rotate the swing plate 11 in the counterclockwise direction at high speed by moving the frame 9 as shown in the figure.
A return spring 13 suspended between the two is biased toward the hanging position. Reference numeral 14 denotes a partition plate installed as desired to divide the lower part of the passage 8 into a rear part 8a and a front part 8b. This has a function of assisting the switching of paths as the swing plate 11 rotates. Further, 15 is a baffle plate that guides coins falling into the passage 8 to the center.

The conveying means 6 is a pair of endless chains 4 which rotate along the guide 3 between the sprockets 2a and 2b.
The chain 4 is fitted with a number of buckets 5, and rollers 16 protruding integrally to the side of the chain 4 are engaged with the guide 3 for assembly. Although not shown in the figure, a driving means such as a motor is connected to one side of the sprocket.

Such a conveyance means 6 includes the swing arm 12.
A bracket 17 is integrally provided at a side opposite to the bracket 17 for engaging with the tip roller 12' of the arm 12 and rotating the arm 12 intermittently in the counterclockwise direction. This bracket 17 is fixed to either the chain 4 or the bucket 5, but as shown in the figure, the bucket 5 is connected to the mounting plate 18 and the pin 1.
When it is swingably installed on the chain 4 via the chain 9, it is preferable that it is integrally fixed to the chain 4 itself.

In a preferred embodiment, the upper opening of the bucket 5 and the lower end of the passage 8 have approximately the same dimensions, and the partition plate 1
The mounting positions of the partition plate 14 and the bracket 17 are set so that the front and rear width of the bucket 4 is larger than the gap between the buckets 5 and the bracket 17 starts to engage the arm 12 as soon as the front end of the bucket reaches the rear end of the partition plate 14. Set. Further, the engagement length of the bracket 17 is set so that the engagement between the bracket 17 and the arm is maintained until the front end of the bucket cart 5 reaches the front end of the passage.

A bar 20 is integrally fixed to the lower side of the bucket 5 and extends forward and backward from the bottom, and a locking member 21 is provided near the descending track of the conveying means 6 to engage with the bar 20 and turn the bucket 5 upside down. Keep it fixed. It is desirable that the bars 20 are provided alternately on the left and right at the bottom of the continuous bucket 5. With this configuration, it is possible to prevent the ends of the bars 20 of the front and rear bucket bags 5 from interfering with each other.
However, in this case, the locking members 21 must be provided on both sides of the conveyance path. The locking member 21 has a arm 23 fixed to the inside of the side plates 22 on both sides supporting the guide rail 3, and a roller 24 rotatably attached to the inside of the tip of the arm 23.
is arranged so as to face the bar 20 of the bucket 5 coming down. With this configuration, wear of the bar 20 and the locking member 21 is prevented, and the bucket can be smoothly reversed.

Next, the operation of the present invention will be explained. The coins carried by the belt conveyor fall from the supply port 1 into the passage 8. The swing plate 11 extends to the position of the partition plate 14, and the arm 12 is in the hanging position.
The roller 16 at the tip faces the orbit of the conveying means 6. At this time, the rear of the leading bucket 5 is below the front passage 8b, and the front of the trailing bucket 5 is below the rear 8a of the passage, so the coin 7 is guided by the swing plate 11 into the leading bucket. be accommodated.

When the bucket cart 5 advances in the direction of the arrow and reaches just before the partition plate 14 as shown in the figure, the bracket 17 corresponding to the bucket cart starts to engage with the arm 12 and rotates the bracket 17 counterclockwise. Since the arm 12 and the swing plate 11 are directly engaged with each other through gears 10a and 10b, the swing plate 11 rotates clockwise at the same time to open the rear passage 8a, and the coins fall into the following bucket bag 5. When the bucket 5 further advances, the engagement between the bracket 17 and the arm 12 is disengaged, and the arm 12 returns to the hanging position by the spring 13 (or its own weight), and at the same time, the swing plate 1
1 returns to its original position, but at this time the tip of the bucket bag 5 has already reached the front end of the passage, so the coin is securely accommodated in the bag bag. Especially rocking plate 1
1 rotates slowly clockwise to gradually open the rear of the passage, and rapidly rotates counterclockwise to instantly close the rear of the passage, causing the coin to bounce forward. In either case, there is no risk that the coin will be caught between the swing plate 11 and the partition plate 14.

The bucket 5 containing coins in this manner is transported along the conveyance path while maintaining a horizontal state, but when it reaches the position of the locking member 21 installed on the descending track of the conveyance path, the bar 20 of the bucket 5 is engaged. Stop member 21
In order to engage with the chute 22, the bucket 5 is forcibly rotated approximately 90 degrees from the horizontal position, and the coin inside is rotated approximately 90 degrees from the horizontal position.
It will be automatically ejected towards.

Although the above description has been made by exemplifying the case where the present invention is used in a coin collecting device of a pachinko ball rental machine, the present invention is not limited to this, and can be widely applied to devices for transferring granular materials, fluids, and other items.

As described above, in the present invention, the swing plate 11 operated by the engagement between the bracket 17 and the arm 12 of the conveying means 6 distributes the articles toward the openings of the continuous buckets at the bottom of the passage, so that the articles are not caught between the buckets. There is no risk of the materials falling through the gaps, and they can be transferred reliably into the bucket.
