Description

[Detailed description of the invention] This invention relates to a conical container separating device, and more specifically, to a conical container separating device that separates and takes out one of the bottommost stacked conical containers. be.

Vending machines for liquid drinks and snacks such as popcorn are equipped with disposable paper containers, which the purchaser takes out and places at the sales counter, then inserts a coin and receives the liquid drink in the container. There are two types of paper containers that automatically appear at the sales counter when a coin is inserted.

An example of the former is that a cylindrical magazine is provided with a rib on the inside that engages with a rib formed at the opening of the container, and this rib prevents the container from falling from the magazine containing the container. The stacked containers are stored in a magazine, which can be taken out by pulling forcefully downwards, and the bottom container and multiple overlapping containers are deformed into an oval shape with a stopper, allowing the container to be removed from the drop opening. There is one that causes one of the lower tiers to fall.

However, in the former case, it is troublesome to have to take out the containers one by one, and in the latter case, there is a lack of certainty in separating the bottom one from the next, and two containers may fall. There were drawbacks.

This invention aims to eliminate the above-mentioned drawbacks, and its features include a cylindrical container magazine with an inner diameter in which the large diameter side of the conical container is inscribed, a machine frame to which this magazine is attached, and a Near the opening edge of the lower end of the magazine, one end is pivotally connected to a fixed pin, the other end overlaps, and a connecting shaft is pivotally connected to the end of the piston rod of the first fluid cylinder, and a tubular body is attached to one end of this connecting rod. A pair of support arms with an air intake hole at one end of the support arm, and an air intake hole at the other end, which is hollow and has a wedge-shaped slope with respect to the vertical plane of the end, and the angle of inclination is greater than that of the upper slope. A fall prevention/separation mechanism is attached to the machine frame, which is formed by a clamping member having an air jet opening in the lower inclined surface with a large inclination angle, and a container that is at least approximately conical than the lower opening edge of the magazine. One end is pivotally connected to the machine frame at a height apart by a support shaft, and the other end has a concave part for receiving the pointed part of the conical container. The piston rod of the second fluid cylinder is pivotally mounted, and when the swinging rod is in a horizontal state at a position where the center line of the conical container housed in the magazine and the center line of the concave portion coincide, the tip of the conical container The apparatus includes a fall prevention mechanism that supports the head part and retreats to a position where the swinging rod does not prevent the conical containers from falling when it is in a substantially vertical state, thereby preventing the conical containers from being taken out in a stacked state. The present invention provides a conical container separation device characterized by:

An embodiment of this invention shown in the drawings will be described in detail below.

As shown in FIGS. 1 and 2, the separation device of this invention includes a cylindrical container magazine 1 having an inner diameter in which the large diameter side of a conical container is inscribed, a fixing pin 2a at one end near the lower opening edge of the magazine, Connecting rods 6a and 6b are pivotally connected to the piston rod 2b, and the other ends are overlapped, and the connecting rods 6a and 6b are pivotally connected to the end of the piston rod 4 of the first fluid cylinder 3 with a connecting shaft 5. A pair of support arms 7a, 7b, air intake ports 8a, 8b are provided at one end of the support arms, and an inclined surface 9a, 9b is formed at the other end to form a wedge shape with respect to a vertical surface 9c at the end. A holding member 11a is formed by opening air jet ports 10a and 10b in a lower sloped surface 9b having a larger slope angle (approximately 60 degrees) than that of the sloped surface 9a.

11b, and a machine frame (not shown) to which the magazine 1 and separation mechanism 12 are attached, which is spaced apart from the lower opening edge of the magazine 1 by approximately the height of the conical container. The receiver is pivoted at one end with a support shaft 13 and has a recess 14 for receiving the pointed part of the conical container at the other end.
The piston rod 19 of the second fluid cylinder 18 is pivoted to approximately the center of the swinging rod 16 to which the cylinder 5 is attached, so that the center line of the conical container a accommodated in the magazine and the center line of the recess are aligned. At this position, the swinging rod 16 is in a horizontal state, and when the swinging rod 16 is in a substantially vertical state, it is configured with a drop prevention mechanism 17 that retreats to a position where it does not prevent the conical container a from falling.

The conical container separation device of this invention is constructed as described above, and the state in which conical containers without flanges (curls) are taken out from the opening stacked in the magazine will be described below with reference to FIGS.

FIG. 3a shows a state in which the lowest end of the stacked conical containers is housed in the magazine 1, and as the first fluid cylinder 3 moves, the holding members 11a and llb move toward the center of the magazine as shown by the arrow. Then, the second cylinder 18 operates in conjunction with the operation of the first cylinder 3, causing the swinging rod 16 to rotate clockwise about the support shaft 13 as shown by the arrow.

As shown in FIG. 3, the clamping member 11
When the vertical surface 9c of a and llb moves to the position where it touches the conical container, the opening edge of the lowest conical container a1 has fallen down with the other stacked containers below the clamping members 11a and llb, and As shown in Fig. 3C, the container in the 3rd and 4th order, which is sandwiched near the opening end of the next conical container a2 and overlaps with the inside of the next conical container, is deformed into an elliptical shape and is connected to the lowermost conical container a1. If a gap is formed between them, and in conjunction with the gap formation, the air flow sent through the support arms 7a, 7b from the air intake ports 8a, 8b is temporarily ejected from the air jet ports 10a, 10b. When air enters the gap as shown by the arrow and the swinging rod 16 is retracted to the vertical position as shown in FIG. The stack completely separates, and the nano falls under its own weight.

When the lowermost conical container a1 falls due to its own weight, the container falls below the fall prevention mechanism 17, as shown in FIG. 3d.
, e, the second cylinder 18 operates and the swinging rod 16 rotates counterclockwise, and the receiver receives the tip of the next conical container a2 through the recess 14 of the seat 15, and the first cylinder 3
When the clamping members 11a and llb move backward as shown by the arrows, they support the entire weight of the stacked containers, and the operation of taking out the next container from the state shown in FIG. This is done in the same way as when removing a conical container.

As mentioned above, this invention includes a container magazine 1 having an inner diameter cylindrical in which the large diameter side of the conical container a is inscribed, and this magazine 1.
One end is pivotally connected to the fixing pins 2a and 2b near the lower opening edge of the magazine 1, and the other end overlaps with the machine frame, and the connecting shaft 5 is attached to the end of the piston rod 4 of the first fluid cylinder 3. Connecting rods 6a and 6b are pivotally connected to each other, integral supporting arms 7a and 7b formed of a tubular body are formed at one end of the connecting rods, and air intake ports 8a and 8b are provided at one end of the supporting arms, which are hollow at the other end. Inclined surfaces 9a and 9b are wedge-shaped with respect to the vertical surface 9c at the end.
The clamping members 11a and 11b are formed with air outlets 10a and 10b on the lower sloped surface 9b, which has an inclination angle larger than that of the upper sloped surface 9a, and are attached to the machine frame. One end of the blocking/separating mechanism 12 is pivotally connected to the machine frame at a location at least approximately the height of the conical container from the lower opening edge of the magazine 1, and the other end is connected to the tip of the conical container. The piston rod 19 of the second fluid cylinder 18 is pivotally connected to the approximately central part of the swinging rod 16 to which the seat 15 is attached, and the receiving concave portion 14 is formed, and the piston rod 19 of the second fluid cylinder 18 is pivotally connected to the center line of the conical container a housed in the magazine. When the swinging rod 16 is in a horizontal state at a position where the center line of the concave portion coincides with the center line of the conical container, it supports the pointed part of the conical container, and when the swinging rod 16 is in a substantially vertical state, it prevents the conical container a from falling. Fall prevention mechanism 1 that retreats to an unobstructed position
7 to prevent the conical container a from being taken out in a polymerized state, so that stacked conical containers without flanges (curls) at the opening can be reliably taken out one by one from the magazine. Even a container made of thin paper sheets, such as a container used to hold popcorn, can be easily separated from a stacked state, and has a simple structure and requires no effort for adjustment.
