Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a cylindrical product is placed on a rotating disk and delivered by rotation of the rotating disk.

Some of these product dispensing machines rotate a drum with a large number of blades on the outside inside a spiral guide rail. Since it has to be loaded along the rail, there are problems such as loading time. In view of the above-mentioned points, the present invention rotates a product placed on a horizontal rotating disk as the rotating disk rotates and gradually sends the product outward and moves it along a circular guide wall. The product is dispensed from a dispensing opening provided on the wall, and the details are as follows.

In FIGS. 1 and 2, reference numeral 1 denotes a circular guide wall fixed to a suitable frame 2 of a vending machine or the like, and a rotary disk 3 is concentrically arranged at the inner lower part of the guide wall.

This disc 3 is fixed to the upper end of a vertical shaft 4 rotatably attached to the frame 2, and the shaft 4 is intermittently driven by a drive device 5 consisting of a motor and a speed reducer. Reference numeral 6 denotes a discharge opening formed in a part of the guide wall 1, and is large enough to discharge one product 7.

A guide plate 8 is provided inside the outlet 6 for guiding the product moving along the guide wall 1 together with the rotary disk 3 to the outlet 6. 9 is the rotating disk 3 from above the guide wall 1.
A plurality of guide members 10, 11, 12 are provided at the lower part of this frame 9, which is an upper frame extending upward.

Each of the members 10 to 12 has an L-shaped bent plate area made of a round bar or the like, and serves to gradually push the rotating product placed on the disc 3 outward. That is, each guide member 10, 11, 12 has a shape shown in the perspective view of FIG. 3 rotates counterclockwise toward the center of the rotary plate 3, the cylindrical product 7 near the center of the rotary plate 3 moves from the center of the rotary plate 3 to the outer periphery as indicated by the arrow a in FIG. so that it is pushed in the direction.

Further, the intermediate guide member 10 guides the product 7, which has been pushed out by the guide member 11 and rotated as shown in FIG. .

The distance between the guide member 12 located at the outermost position and the inner periphery of the guide wall 1 is made slightly wider than the diameter of one product, and the product 7 pushed out by the guide member 10 is
2 is guided in the direction of arrow c to a position where it comes very close to the inner periphery of the guide wall 1.

In the above embodiment, a large number of products 7 such as bottles and cans are placed on the disk 3, and the products 7 on the outside are loaded along the inside of the guide wall 1, and the products 7 at the tip face the outlet 6. . In this way, the disc 3 is rotated intermittently, and one pitch is set so that the product 3, which is located closest to the inner periphery of the guide wall 1 and moves together with the disc 3, moves the same distance as the diameter of this product 3. . That is, when the disk 3 rotates by one pitch in the direction of the arrow in FIG. and is paid out. As described above, one product 7 is dispensed from the dispensing port 6 every time the disc 3 rotates by one pitch in response to the dispensing signal. It is gradually pushed outward. - That is, as mentioned above, when the product 7 closest to the center rotates together with the disk 3, it first comes into contact with the guide member 11, is pushed outward by this, rotates further together with the disk 3, and then further It contacts the guide member 10 and is further pushed outward. The product 7, which has been successively moving outward in this way, is finally pushed out by the guide member 12 to a position very close to the guide wall 1, moves along the guide wall 1, and enters between the guide plate 8 and the guide wall 1. go. In addition, in the above-mentioned action, product 7 has a chi. If there is a risk of clogging near the inner end d of the guide plate 8, as shown in FIG. A movable rocking plate 15 is provided, and the rocking plate 15 is rocked once every time the disk 3 rotates by one pitch.

An example of this swinging mechanism will be explained based on FIGS. 3 and 4. Reference numeral 16 denotes a reciprocating rod that is attached to move forward and backward in the radial direction along a guide 18 at the bottom of the frame 2, and its outer end is It is connected to the rocking plate 15 by a connecting pin with some play, so that the rocking plate 15 swings about the shaft 14 when the advancing/retracting rod 16 advances or retreats. A cam 17 is fixed to the shaft 4, and a roller at the inner end of the reciprocating rod 16 is pressed against the outer periphery of the cam 17 by a spring 19. An unevenness is formed on the outer circumference of the cam 17, and by making the pitch of the unevenness equal to the pitch of the intermittent rotation of the disk 3, when the disk 3 rotates by one pitch, the advancing/retracting rod 16 advances and retreats once. Although the swing plate 15 swings once, it may swing two or more times while the disc 3 moves one pitch.
, 12 and the guide plate 8 in the same manner, clogging in the guide members 10 to 12 and the guide plate 8 can be eliminated. A drive device 5 for the shaft 4 that rotates the disk 3
Examples include a method in which a stepping motor and a speed reducer are combined and driven intermittently by pulse signals, and a method using a mechanism as shown in FIG. 5.

In the case of FIG. 5, an intermittent drive mechanism is provided in the machine box 21 of the drive device 5.

That is, a ratchet wheel 22 is fixed to the shaft 4, and a lever 23 rotatably attached to the shaft 4 has a feed pawl 24 that engages and disengages from the ratchet wheel 22;
A spring 25 is attached to press the feed pawl 24 to the teeth of the ratchet wheel 22. 26 is a motor fixed to the machine box 21, and its shaft 2
7 is placed in a machine box 21, and a crank 28 fixed to this shaft 27 and the outer end of the lever 23 are connected by a link 29.

Further, a check pawl 30 is provided inside the machine box 21, and a spring 31 for pressing the pawl 30 against the ratchet wheel 22 is provided. In the case of this ratchet mechanism, when the payout signal enters the control circuit of the motor 26, the shaft 27 of the motor 26 rotates once and then stops. Therefore, the crank 28 rotates once, the lever 23 is reciprocated once through the link 29, and the ratchet wheel 22 is intermittently rotated at a constant pitch in the direction of the arrow by the action of the feed pawl 24 and the check pawl 30. Further, in addition to the ratchet mechanism as described above, an intermittent drive mechanism similar to the ratchet mechanism can be constructed by combining a drive freewheel and a non-return freewheel.

In the present invention, as described above, the products placed on the rotating disc within the circular peripheral wall are moved outward by the guide member as the disc rotates and are delivered from the dispensing port, so that the products are automatically aligned. It will be held on.

Therefore, when loading the products for the first time, it is only necessary to pay attention to the arrangement of the products in the vicinity of the dispensing opening, and the other products can be placed casually, making it extremely easy to load the products. Furthermore, in the case of the one-stage dispensing machine of the present invention, the height is only slightly higher than the height of the products, so it is extremely low compared to conventional dispensing machines, and in the conventional drum type, the products are only lined up on the outside of the drum. However, in the dispensing machine of the present invention, since the products can be placed near the center of the disc, there is an effect that a considerable number of products can be stored in spite of the low height of the dispensing machine.
