Abstract

PURPOSE:To make it possible to work on a packaged body from at least three directions by a method wherein in a former half process, the front and rear of a packaged body is reversed in such a manner that a surface of the packaged body which faces inward in the radial direction of one turret faces outward in the radial direction of the other turret in a latter half process, and the packaged body is transferred to the other turret type packaging mechanism. CONSTITUTION:When a packaged body reversing transferring mechanism 3 transfers a packaged body P from one turret type packaging mechanism 1 to the other turret type packaging mechanism 2, the phases of front and rear of the packaged body P are reversed in the cases when they are to the radial direction of a turret 11 of one packaging mechanism 1 and when they are to the radial direction of a turret 21 of the other packaging mechanism 2, and become the opposite phases. Therefore, in a series of packaging processes, it becomes possible to work on the packaged body P from three directions which confront the front and rear both surfaces and the top surface.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a packaging machine for packaging products, and more specifically, the present invention relates to a packaging machine for packaging products. The present invention relates to a series of processing devices that perform packaging processing on products using a processing mechanism.

(Prior Art) Conventionally, as a means of packaging products, there have been line-type packaging machines that perform a series of packaging processes on a processing line in which packaging mechanisms are linearly arranged, and packaging machines that perform a series of packaging processes on the circumference of a turret. A turret-type packaging machine is well known in which a series of packaging processes are performed by a mechanism and a packaging mechanism disposed close to the turret.

(Problems to be Solved by the Invention) Since the line-type packaging machine has a linear processing line, it is difficult to arrange a series of packaging processing mechanisms on both sides and above the processing line. This makes it possible to easily perform packaging processing operations on the package moving along the processing line from at least three directions, such as from both sides of the processing line and from above.

However, since the line-type packaging machine has packaging processing mechanisms arranged in a straight line, it requires a long working space and is difficult to install unless it is in a large space.

On the other hand, a turret-type packaging machine has a turret with packaging processing mechanisms arranged in a row on the circumference of the turret, and a packaging processing mechanism arranged on the outside or above the turret circumference.
Since packaging work is performed on the packages held by the arrayed packaging mechanisms and traveling along the rotational orbit of the turret, the packaging mechanisms are concentrated around the peripheral surface of the turret body and around the turret. This allows high-density packaging processing work to be carried out in a relatively limited work space.

However, there is no extra space inside the turret circumference,
Furthermore, since the turret's rotating shaft and rotational drive mechanism are located at the center of either the upper or lower surfaces of the turret or one of the surfaces, it is not possible to arrange the packaging processing mechanism in the space inside the turret's circumferential surface. This is extremely difficult, and it is virtually impossible to perform processing on the surface of the package facing inward in the radial direction of the turret.

Therefore, there is a problem in that the processing operations for packaging bodies in the turret type packaging machine are limited to processing operations from two directions: the outer side and the upper side of the turret circumferential surface.

(Means for Solving the Problems) This invention solves the drawbacks of both the line-type packaging machine and the turret-type packaging machine as described above, and also has the advantages of both. The purpose is to provide reverse feed processing equipment,
To achieve this, the following configuration was adopted. That is, one turret-type packaging mechanism in which the packaging mechanism responsible for the first half of the series of packaging processes is arranged in a row on the peripheral surface of one turret, and the second half of the series of packaging processes. A packaging reversing and transporting mechanism is interposed between the packaging processing mechanism that handles the processing and the other turret type packaging processing mechanism that is arranged in a row on the peripheral surface of the other turret, and the packaging reversing and transporting mechanism is connected to the one turret type When the package that has completed the first half of the packaging process in the packaging processing mechanism is transferred to the other turret-type packaging mechanism, the surface of the package that faces inward in the radial direction of the one turret in the first half processing process is In the latter processing step, the packaging body in the turret-type packaging machine is turned over so that it faces outward in the radial direction of the other turret, and is transferred to the other turret-type packaging processing mechanism. Created a front/back reversal feed processing device.

(Function) First, in one turret-type packaging processing mechanism that is responsible for the first half of a series of packaging processing steps, the packaging processing mechanisms arranged in a row on the peripheral surface of one of the turrets form a package while forming the package. It moves along the rotating orbit of one turret.

At this time, machining work can be performed from two directions: the outside of the circumferential surface of the one turret and the upper part of the circumferential surface of the one turret, but machining work cannot be performed on the inside of the circumferential surface of the one turret. Since there is no possible free space,
No machining operation is performed on the radially inward surface of the one turret in the package.

Next, the package reversal transfer mechanism transfers the package whose first half has been wrapped in the one turret-type packaging mechanism to the other turret-type packaging mechanism.

At this time, the surface of the package that could be processed outward in the radial direction of the - side turret in the first half processing step and the surface of the package that could be processed outward in the radial direction of the one turret and processed inward in the radial direction of the one turret After reversing the front and back sides of the packaging body in order to reverse the surface of the packaging body, which was impossible to Transport.

In the other turret-type packaging processing mechanism, the packaging processing mechanisms arranged in a row on the peripheral surface of the other turret move along the rotational trajectory of the other turret while holding the package that has been turned upside down.

At this time, the surface of the package that was inward in the radial direction of one turret and could not be processed in the first half of the packaging processing step is turned outward in the radial direction of the other turret. Machining work becomes possible.

Therefore, in the turret-type packaging machine of the present invention, the packaging body reversal feed processing device has at least three
It becomes possible to perform machining work from two directions.

(Example) Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 1 shows a mechanism for reversing packaging bodies according to the present invention, in which one turret-type packaging mechanism 1 is responsible for the first half of a series of packaging processes, and the other is a turret-type packaging mechanism 1 that performs the first half of a series of packaging processes, and An inside-out reversing transfer mechanism 3 is interposed between the other turret-type packaging processing mechanism 2 which is responsible for the latter half of the packaging processing process, and the transfer mechanism 3 includes a package holding part 35 provided on the peripheral surface of a transfer turret 31. , the rotational trajectory C of the transfer turret 3I is the same as the rotational trajectory A of one turret l in the one turret packaging mechanism l and the rotational trajectory of the other turret 21 in the other turret packaging mechanism 2. It intersects with B.

The package holding part 35 includes a pair of arms 32 and 32 that face each other with a gap that can horizontally hold the package P, and whose base ends are pivotally supported by the transfer turret 31.
' are arranged in rows at equal intervals on the circumferential surface of the transfer turret 31, and rollers 3
3, and a spring 34 for pressing each arm against the package P is elastically installed between adjacent arms.

In one turret-type packaging processing mechanism l responsible for the first half of a series of packaging processing steps, the packaging processing mechanism is held in a row on the peripheral surface of one turret 11,
The package P, which is formed while traveling along the rotational path A of the one turret, is processed from the outer side or the upper part of the circumferential surface of the one turret 111, and the first half of the packaging process is completed.

At this time, the back surface P' of the package facing inward in the radial direction of one of the turrets 11, for which there is no extra space for processing, completes the first half of the packaging without being subjected to processing.

The package P that has completed the first half of the packaging process further advances on the rotational path A and reaches the intersection AC with the rotational path C of the transfer turret 31 of the front-back transfer mechanism 3.

The package P that has reached the intersection AC enters the gap between the arms 32 and 32' from the open part of the arm 32. 32', it is clamped from the horizontal direction.

A horizontally rotating roller 33 is provided at the part of the arm 32, 32' that contacts the package, and the package P is moved between the arms 32 and 3.
2', so that the package P traveling in the horizontal direction on the rotating orbit A can smoothly enter the gap between the arms 32 and 32', and It is securely held without moving in the vertical direction.

As the transfer turret 31 rotates, the package P held between the arms 32 and 32' moves around the turret 31.
It travels along the rotational trajectory C of the other turret type packaging processing mechanism 2 and is transferred to the intersection BC with the rotational trajectory B of the other turret 21 in the other turret type packaging processing mechanism 2.

Then, the packaging processing mechanisms arranged in a row on the peripheral surface of the other turret hold the packaging P and move horizontally along the rotational path B in the direction in which the arms 32 and 32' are opened.
The package P smoothly leaves the gap between the arms 32 and 32', advances on the rotational path B, undergoes the latter half of the processing operation, and completes a series of packaging operations.

At this time, the back surface P' of the package P which was not subjected to the processing operation because it faces inward in the radial direction of one of the turrets 11 in the one turret type packaging processing mechanism 1.
However, in the other turret type packaging processing mechanism 2, it faces outward in the radial direction of the other turret 21, so that it can receive processing work.

That is, when the package reversal transfer mechanism 3 transfers the package P from one turret-type packaging processing mechanism 1 to the other turret-type packaging processing mechanism 2, the front and back phases of the package P change to the above-mentioned packaging processing mechanism! The radial direction of one turret 11 of the packaging processing mechanism 2 and the radial direction of the other turret 21 of the packaging processing mechanism 2 are reversed and the phases are opposite. Processing operations can be performed from at least three directions, facing both the front and back surfaces and the top surface.

FIGS. 2 and 3 show a specific example of a series of packaging processing mechanisms according to the present invention, in which one turret type packaging processing mechanism 1, which is responsible for the first half of the processing process, is raised and lowered on one side, and one turret 11 is moved up and down. Four blades b that can be opened and closed in the radial direction and form the four vertical corners of a prismatic space when opened.

Consists of b, b', b'.

Furthermore, above the rotational path A of the turret 11 along which the package forming mechanism 12 advances, a heat shrink film tube supply mechanism 13, a mount supply mechanism 14, and a packaged article supply mechanism 15 are arranged.

Moreover, a clamping mechanism 22 capable of vertically clamping the package P is mounted on the peripheral surface of the other turret 21 in the other turret-type packaging processing mechanism 2 that handles the latter half of the processing process.
．． 22' are arranged in a row at equal intervals, and a temporary contraction heater 23 is placed on a concentric circle having a larger diameter than the rotational orbit B of the other turret 21, at a position close to the package P traveling on the rotational orbit B. Install.

Then, the package P that has further advanced on the rotating orbit B close to the temporary contraction heater 23 is moved to the clamping mechanism 22.22.
The heater tunnel mechanisms 24 are installed at positions that are successively removed from '.

Furthermore, a package reversing and transferring mechanism 3 shown in FIG. 1 is interposed between the one turret-type packaging processing mechanism 1 and the other turret-type packaging processing mechanism 2 to constitute a series of packaging processing mechanisms. (See Figures 2 and 3).

One of the turret-type packaging processing mechanisms responsible for the first half of the packaging process is the heat-shrinkable film tube supply mechanism 13, which cuts the heat-shrinkable film tube T to a desired length, and the packaging located directly below it. It is supplied to the body forming mechanism 12.

At this time, the blades b, b of the package forming mechanism 12,
Since b' and b' are closed in the upward position, this blade is inserted into the film tube T.

With the intermittent rotation of one of the turrets 11, the package forming mechanism 12 advances the rotational trajectory A of the turret 11 to just below the mount supply mechanism 14, and passes the film tube T.
Blade b inserted into.

Release b, b', b' in an ascending position.

Then, the film tube T is formed into a prismatic shape having openings at the top and bottom, and the mount supply mechanism 14 inserts the mount into the prismatic film tube T.
The package forming mechanism summer 2 includes the prismatic film tube T.
While maintaining the shape of the rotating orbit A, the packaged product supply mechanism 1
Proceed to just below 5.

The packaged product supply mechanism 15 loads a predetermined number of packaged products G (for example, photographic film in a box, etc.) into the film tube T, which has the mount inside, to form a package P. This completes the first half of the processing process.

That is, the first half of the packaging process is shown in Figure 4 I.

As shown in H, first, a heat-shrinkable film tube T cut to a desired length is formed into a prismatic shape, and a backing paper is placed inside it to provide convenience for display and to reinforce the packaging. A package P is formed by loading a number of products G to be packaged.

The package P formed in the first half processing step has the package forming mechanism 1 at the four inner corners of the heat-shrinkable film tube T.
The blades b, b, b', and b' of No. 2 continue to advance along the rotational path A with the blades b, b, b', and b' inserted therethrough, and the package reversing transfer mechanism 3
reaches the intersection AC with the rotational trajectory C.

Then, the package P is horizontally clamped by the arms 32, 32' of the package clamping section 35 of the package reversing and transferring mechanism 3, and the blades b, b.

After b' and b' descend and separate from the heat-shrinkable film tube T, they are reversely transferred along the rotational trajectory C of the transfer turret 31 having the package holding part 35,
It reaches the intersection BC with the rotational trajectory B of the turret 21 in the other turret packaging processing mechanism 2 which is responsible for the latter half of the processing.

The back surface P' of the package P (i.e., the surface on which the mount is located), which was facing inward in the radial direction of one turret 11 in the first half of the processing step, is now facing toward the other turret 21 in the second half of the processing step. While facing outward in the radial direction, the package is clamped from above and below by the clamping mechanisms 22, 22', leaves the package inverting and transferring mechanism 3, and travels along the rotational path B.

At this time, the temporary contraction heater 23 installed close to the outer side of the rotating orbit B is activated to
The heat-shrinkable film tube T located in the section is heat-shrinked to tighten the packaged product G and the mount loaded in the film tube T.

The package P that has been processed by the temporary shrink heater 23 and has further progressed along the rotational path B is moved to the clamping mechanism 22.22.
', and the entire film tube T is heated and shrunk by the heater tunnel mechanism 24 installed at the detached position to complete the latter half of the packaging process.
Complete a series of packaging processes.

The above-mentioned series of packaging operations are carried out one after another, and processed packages P as shown in FIG. 4 (2) can be successively obtained.

Note that if it is necessary to attach a label or the like to the package P that has undergone the series of packaging processes, it is also possible to provide a label attaching mechanism 25 at the end of the heater tunnel mechanism 24.

The packaging body P traveling on the rotational path A can be processed from the outside and upper part of the circumferential surface of the turret 11, and the front-side reversing transfer mechanism 3 reverses the front and back of the packaging body P. Then, by transferring the package P to the rotational orbit B of the other turret 21 in the other turret type packaging processing mechanism 2 which is responsible for the latter half of the processing process, the package P is transferred to the radially inner side of one turret 11 in the first half of the processing process. The surface P' of the package, which cannot be processed because it moves inward on the rotational trajectory A, is
