Abstract

PURPOSE:To enable to eject an object to the outside when it is discharged, by a method wherein a projection part, compressing a rotary spiral body with the conveyance of the object, is formed on the spiral body which is used with an automat and conveys forward the objects in order. CONSTITUTION:If, with a motor 3 run, a spiral 2 is turned, the spiral 2 is displaced so that a commodity 1 is pushed forward at each revolving part, and thus, the commodity 1 is advanced. If the spiral 2 exceeds a given rotary angle range, a projection part 6, engaging a frontmost terminal 2a of the spiral 2 to compress the spiral 2, is released from said engagement to release a compression force momentarily, and ejects the commodity 1 to a drop path 7 side from a stowing shelf 4 in a manner to strike the front-most commodity 1, already pushed to a front end, on the rear with an elastic power.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a marked line type article discharging device used in vending machines and the like.

An automatic vending machine in which articles are inserted and stored in each space between adjacent rotating parts of a screw, and a group of articles are sequentially advanced to a discharge position by rotating the screw around its longitudinal axis. In article discharging devices such as machines, there is a problem in that articles pushed out from the front end of the marking line tend to roll and fall from the article shelf on which the articles were placed, causing them to become stuck in the space of the falling path. In particular, for thin board products such as record boards with flexible packaging, product 1 is shown in Figure 4.
Even if part 11 of the record remains flat, the corner im
) is bent and has an island, so the product 1 is pushed forward, and a phenomenon occurs in which the corner 1t+ bent from K gets caught in the bottom of the next product 1. Therefore, the product 1 is pushed out from the front end of the marked line and carried out. There is a problem in which product 1 gets stuck in the state shown by the IC in Figure 6 while being sandwiched between the following products, and this problem can occur even with other thin products if the packaging is poor. There is a danger that the same situation as above will occur.

In view of these circumstances, the present invention not only transports the articles forward one by one using the turning part of the screw as in the past, but also transfers the articles pushed to the front end of the marked line by imparting elastic force to the screw. This was done with a focus on further ejecting the energy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Below, a case where the present invention is applied to a product discharging device of a vending machine will be described based on an embodiment shown in the drawings.

FIG. 1 is a cross-sectional view of a product storage shelf to clearly illustrate the ejecting device of the present invention, and FIG. 2 is a diagram showing the product ejecting operation. Moreover, FIG. 3 is a view of the storage shelf portion of FIG. 1 viewed from the front.

In the figure, 2 is a screw made of a spring member such as a spring stainless steel wire, and the electric motor 3 with a speed reducer is the power source.
It is configured to be rotationally driven around a longitudinal axis by.

Reference numeral 4 denotes a product storage shelf on which products l are inserted between adjacent rotating portions of the screw fastening 2 and arranged in the front-rear direction;
In the central portion of the storage shelf 4, a longitudinal hole 15 is formed into which the lower end position of the pivoting portion of the screw fastener 2 is inserted.

Further, in the groove 5 of the storage shelf 4, the screw 2 engages with the turning portion of the front end of the screw 2 recessed into the groove 5 at each predetermined rotation angle range of the screw 2, and rotates the screw 2 in the longitudinal direction. A protrusion 6 is provided which is compressed.

Furthermore, a contact plate 8 is disposed at the front upper part of the storage shelf 4 for contacting the upper end portion of the product 1 discharged from the storage shelf 4 and guiding the product 1 to the fall path.

Next, the ejection operation of the product 1 will be explained.

First, when the product discharging device is in a standby state as shown in FIGS. 1 and 3, the electric motor 3 is driven to move the spiral 2 in the direction of arrow A.
When rotated in the direction, the screws 2 are displaced so as to push the product 1 forward at each turning portion, thereby moving each product 1 forward.

However, since the front end of the screw 2 was engaged with the protrusion 6 and its displacement in the longitudinal direction was suppressed, it gradually became compressed, and the product 1 at the front came off the screw 2 and was pushed forward. In this state, the compression state reaches almost the maximum as shown in FIG.

In this state, when the screw #2 further rotates in the direction of arrow A and exceeds the predetermined rotation angle range from the start of rotation, the screw #2
Since the frontmost end 2a of the product l disengages from the protrusion 6 and disengages, the compressive force is instantly released, and the elastic force of the product hits the rear side of the product l, which has already been pushed out to the front end. One ejection operation is completed by ejecting the container from the storage shelf 4 toward the falling path M.

At this time, since the protrusion 6 is disposed below the product 1, the screw 2 applies a resilient force to the bottom surface of the product 1, so that the product 1 appears to be subject to a forward tilting force. The product can be ejected in a stable falling position without becoming unstable.

Moreover, as shown in Fig. 5, even if the corner 1b of the package of the product L to be discharged is caught on the bottom surface of the product L on the rear side, the bottom part of the product L is held by the elastic force. Since most of the liquid is forcibly ejected, it can be ejected safely and reliably.

Furthermore, it also has the effect that the ejecting stroke of the foremost product can be made larger due to the ejecting effect caused by the elastic force.

In particular, by forming the front end 2a of the screw 2 by slightly bending it outward in the longitudinal direction as shown, it is possible to increase the elastic force and ejection stroke of the screw 2.

Then, the above ejecting operation is performed by one rotation of screw #2 (=360°).
By repeating this operation each time a sales signal is received from the outside and rotating it one rotation at a time, the products 1 placed on the storage shelf 4 can be reliably discharged in order from the front.

On the other hand, the present invention is not limited to the embodiments described above, and can be implemented as appropriate without departing from the idea thereof.
For example, it is obvious that a corresponding effect can be obtained even if the arrangement position of the protrusion 6 is slightly changed.

As explained above, the present invention enables a marked line type article discharging device to not only move the article forward by simply pushing it out with a rotating part as in the conventional case, but also to provide elasticity to the screw itself so that the article can be pushed out once. The article is ejected each time the ejecting operation is performed, and it has an excellent effect in that it can safely and reliably eject thin plate articles such as records.
