Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a device for separating and taking out conical containers, and more specifically, the invention relates to a device for separating and taking out conical containers. The present invention relates to a conical container separation and extraction device capable of separating one of the lowermost containers from the container holder and automatically changing the direction of the conical container.

[Conventional technology]

This type of conical container separation and extraction apparatus is conventionally described in, for example, Japanese Utility Model Application No. 59-40984.

This conventional technology includes a container holder equipped with a separation member having a sloped surface at the lower end leading to an opening with a diameter gradually smaller than the opening diameter of the container, and a vacuum pad located below the holder and rotated by being attached to a rotating shaft. It is characterized by being comprised of a container take-out mechanism equipped with a rotating rod, an elevating mechanism that moves the mechanism up and down, and a vacuum mechanism that is connected to the vacuum part and has the function of adsorbing the container to the part. This is a separation and extraction device for conical containers.

Apart from this, there is also one described in Japanese Utility Model Publication No. 60-29035.

This conventional technology consists of a cylindrical container magazine with an inner diameter in which the large diameter side of a conical container is inscribed, a machine frame to which this magazine is attached, one end of which is pivoted to a fixed pin near the lower opening edge of the magazine, and the other end of which is overlapped. At the same time, there is a ring rod pivotally connected to the end of the piston rod of the first fluid cylinder with a connecting shaft, a pair of supporting arms formed of a tubular body at one end of the connecting rod, and an air rod at one end of the supporting arm. The intake port is hollow at the other end and has a wedge-shaped inclined surface with respect to the vertical surface of the end, and an air outlet is opened in the lower inclined surface with an inclination angle greater than that of the upper inclined surface. A fall prevention/separation mechanism formed by a clamping member and attached to the machine frame, and one end pivoted to the machine frame at a location at least approximately the height of the conical container from the lower opening edge of the magazine, and the other end The piston rod of the second fluid cylinder is pivotally mounted approximately at the center of the swinging rod, which is equipped with a receiving seat having a concave portion for receiving the pointed portion of the conical container, so that the piston rod of the second fluid cylinder is pivoted to the center line of the conical container housed in the magazine. When the swinging rod 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 is in a substantially vertical state, it is in a position that does not prevent the conical container from falling. This is a conical container separation device characterized in that it is configured with a fall prevention mechanism that moves backward, and is capable of preventing the conical containers from being taken out in a superposed state.

[The problem that the idea attempts to solve]

Among the above-mentioned conventional techniques, the one disclosed in Japanese Utility Model Application Publication No. 59-40984 is one in which one of the containers stacked in the holder is adsorbed by a vacuum pad inserted into the holder as the container ejection mechanism rises. The container separated by the separation mechanism is taken out of the holder as the container removal mechanism descends, and the container is turned upside down by rotation of the rotating shaft,
This is a conical container separation/retrieval device that allows a conical container that is weak and difficult to handle to be mechanically removed from a holder.

However, in this conventional device, when the container A is deformed as the glue at the joint D dries and hardens, as shown in FIGS. Since the average is no longer in contact with the average, air may leak from the gap between the suction part C and the inner surface of the container, resulting in incomplete suction, or as shown in FIG. If this occurs, there is still a problem that air leaks from the gap between the adsorption section C and the joint D of the container, resulting in incomplete adsorption, as described above.

Furthermore, although the prior art shown in Japanese Utility Model Publication No. 1983-29035 is provided with a pressing mechanism, this conventional technology does not support the lowermost part of a large number of conical containers stacked vertically in a magazine. After pressing the clamping member around the second conical container from the bottom while avoiding the upper edge of the conical container, air is blown from the air outlet to blow air into the upper edge of the lowest conical container. Only the lowermost conical container is blown away and separated using the pressure of blown air.

Therefore, the direction in which the blown conical container is blown is not constant, and therefore it is difficult to catch the blown conical container. Since it must be installed separately from the fall prevention/separation mechanism installed at the bottom of the magazine,
There are many problems, such as the need for two container fall prevention mechanisms, which complicates the structure, and disadvantages in terms of space and cost.

In order to eliminate each of the above-mentioned problems, this invention has been developed by pressing a conical container against the vacuum pad with a piston to cause it to be absorbed, and after separating the adsorbed conical container by lowering the vacuum pad,
The purpose is to be able to take it out and use it by flipping it upside down.

[Means to solve the problem]

A cylindrical container holder that accommodates a plurality of conical containers that are sequentially polymerized with their pointed ends facing upward, and an opening that is disposed at the bottom of the container holder and gradually becomes smaller in diameter than the opening diameter of the conical container. A separation member having an inclined surface and a vacuum pad that moves up and down along a center line in the lower part of the container holder and whose lower part is attached to a rotating shaft disposed along a line intersecting the center line and rotates up and down. A conical cone having a container take-out mechanism equipped with a moving rod, a lifting mechanism that raises and lowers the container take-out mechanism along the center line, and a vacuum mechanism that communicates with the vacuum pad and causes the conical container to be attracted to the vacuum pad. In configuring the container separation and extraction device, the inner surface of the lowermost conical container among the plurality of conical containers is moved upwardly by a piston passing through one through hole provided on the lower circumferential surface of the container holder. A pressing mechanism for pressing against the air suction part of the vacuum pad is provided on the lower outer peripheral surface of the container holder,
The tip of the piston of the pressing mechanism presses the inner surface of the lowermost conical container against the air suction part of the vacuum pad, and the lowermost conical container is attracted to the vacuum pad by the air suction force of the vacuum mechanism, and the attracted lowermost conical container is This is achieved by allowing the container to be taken out of the container holder via the separation member by lowering the vacuum pad.

[Effect]

As the container ejecting mechanism rises, only the lowest one of the containers stacked in the container holder is pressed against the vacuum pad inserted into the inside of the conical container in the container holder with the piston of the pressing mechanism to attract it. , the conical container separated by the separation member as the container ejecting mechanism descends is taken out of the container holder, and the taken out conical container is turned upside down by rotation of the rotation shaft and taken out to the outside. .

In addition, even if conical containers made of thin paper sheets are stacked and each conical container is deformed, it is difficult to handle.
You can reliably take them out one by one.

〔Example〕

Examples will be described with reference to the drawings.

First, the basic components of this invention are: a container holder 2 equipped with a separating member 25 having a sloped surface 26 at the lower end that gradually reaches an opening with a smaller diameter than the opening diameter of the conical container A; Container removal mechanism 4 equipped with a rotating rod 49 with a vacuum pad 48 located below and attached to a rotating shaft 46 to rotate.
and a lifting mechanism 3 that lifts and lowers the container removal mechanism 4.
a vacuum mechanism that communicates with the vacuum pad 48 and causes the conical container A to be attracted to the pad 48; and a pressing mechanism that presses the conical container A against the vacuum pad 48 with a piston 61 through the through hole 64 of the container holder 2. It consists of 6.

Next, a specific example of this invented device will be explained.

As shown in FIGS. 1 and 2, in the device of this invention, a container holder 2 and a lifting mechanism 3 are attached to an upper horizontal plate 11 constituting a U-shaped machine frame 1. Two guide rods 14 installed parallel to the vertical plate 13 between the lower horizontal plate 12
A container take-out mechanism 4 is attached to the mounting frame 41 which constitutes the container take-out mechanism 4, and an air cylinder 31 which constitutes the lifting mechanism 3.
A piston rod 32 is attached.

The container ejecting mechanism 4 is attached to the side surface of the above-mentioned mounting frame 41 via a mounting plate 42, and includes a rotary actuator 45, a rotating shaft 46 rotated by this actuator, and a vacuum mechanism 50 attached to the rotating shaft 46. A rotating rod 49 is attached to which a vacuum pad 48 connected via a vacuum hose 47 is attached to the tip.

The container holder 2 is shown in each of the above figures and in Figure 3a,
b. As shown in FIGS. 4a, b, and c, an air piston cylinder mechanism 6 consisting of a cylinder 63 and the like having a piston 61 and an elastic spring 62 installed in a relatively lower part.
A cylindrical holder pipe 21 having an inner diameter slightly larger than the outer diameter of the opening of the conical container A having a pressing mechanism 6 to which an air pressure feeding pipe P is connected to the holder pipe P, and a cylindrical holder pipe 21 having a trapezoidal cross section and fitted into the holder pipe 21. A mounting portion 22 for attaching the holder pipe and a tapered extraction hole 23 whose inner diameter is equal to the inner diameter of the holder pipe at the end of the mounting portion and gradually decreases to about 15% of the diameter up to the opening end. The separation member 25 includes a heavy extraction prevention part 24.

The double extraction prevention portion 24 has an extraction hole 23 therein.
In order to increase the contact resistance with the conical container, the peripheral surface of the container is provided with an inclined surface 26 with a narrow groove in the circumferential direction and radial cut grooves 27.

The vacuum hose 47 is connected to a pan-shaped member 44 attached to the side plate of the rotating shaft 46, and the vacuum hose 47 is connected to the vacuum pad 48 through a ventilation hole formed in the rotation rod 49 that communicates with the ventilation hole.
It is connected with.

The device of this invention is constructed as described above.
The operation of taking out the conical containers stacked in the container holder will be described below.

First, as shown in FIG. 5a, according to the operation of the elevating mechanism 3, the container ejecting mechanism 4 in the position shown in FIGS. 1 and 2 is moved by the piston rod 32 to the guide rod 1.
4, and the rotating rod 49 is inserted into the container holder 2 as shown in FIG. 5b.

Next, the air piston cylinder mechanism 60 operates as shown in FIG.
When the conical container A is pressed against the vacuum pad 48 through the through hole 64 of the container holder in the direction shown by the arrow against the elastic force of It touches the inside of the lowermost conical container A1.

Here, when the vacuum mechanism 50 operates and air is sucked through the vacuum hose 47 to create a negative pressure in the vacuum pad, a part of the conical container A1 is attracted to the vacuum pad as shown in FIG. When the air pressure feeding of the air piston cylinder mechanism 60 is released, the piston 61 returns to its original position by the elasticity of the spring 62.

After this, the lifting mechanism 3 operates as shown in FIG.
When the conical container A1 is returned to the position shown in FIG. 4 and FIG. 2 It is taken out.

Therefore, even if the conical container A2 is tried to be taken out due to the frictional resistance between the conical container A1 and the conical container A2, the resistance of the double take-out prevention part 24 is large and the conical container A
2 remains in the container holder 2.

After this, the rotary actuator 45 further rotates the rotating shaft 46, and along with this rotation, the rotating rod 49 rotates 180 degrees toward the front as shown in Fig. 5 f, and is removed from the reverse position. The conical container A1 that has been removed is returned to its normal position, and the conical container A1 that is attracted to the vacuum pad 48 is released by stopping the operation of the vacuum mechanism.
The container is handed over to a container receiving mechanism (not shown).

At this time, the vacuum pad may switch the airflow to make the air a positive pressure and forcibly blow out the conical container A1.

When the series of operations for taking out the conical containers is completed in this way, the rotary actuator 45 operates to rotate the rotating rod 49 by 180 degrees again as shown in FIG. In preparation for unloading, the conical container A2 is unloaded through the same process as described above, and the same applies thereafter.

This series of operations is controlled by a sequencer or microcomputer.

Incidentally, n (n is a positive plural) rotating rods 49 are attached to the rotating shaft 46 of the conical container separation/retrieval device of this invention at regular intervals, and a total of n rotating rods 49 are attached at regular intervals from n container holders 2. It is also possible to take out individual conical containers, and the structure of the container take-out mechanism 4 etc. on which the rotation shaft 46 is supported is the same as the basic structure shown in FIGS. 1 and 2.

The mechanism for preventing stacked conical containers from falling is the separation member 2.
