Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging machine for cigarettes or other articles, and more particularly to a wrapping paper holding device for use in an arbor-tape packaging machine.

The present invention is useful for machines that manufacture well-known "soft packs" used for cigarette packaging, that is, cigarette packets made from non-thick packaging materials, such as wrapping paper, by winding them around the outer circumference of ARμ. In particular, a device is planned for holding the above-mentioned packaging paper on one side of the outside of the arm, between a presser plate facing thereto, and for opening and closing the presser plate.

The arboret used in this type of packaging machine has a disk shape with arμ arranged at equal intervals on the circumference.
The walkway rotates around the central axis and rotates forward intermittently at intervals of the arm μ arrangement.

A wrapping paper supply means is disposed at a fixed position outside the arboret. The term "wrapping paper" as used herein refers to the inner wrapper aluminum foil and wrapping paper commonly used for soft packs, but other similar packaging materials can also be used if necessary. In this machine, the aluminum foil and wrapping paper are fed by the paper feeding devices respectively disposed at different fixed positions.

The aluminum foil supplied along one side of the outside of the arc is wound around the four sides of the arc to form a cylindrical shape, and one end of the cylindrical shape is folded in and the other end is opened. It is then molded into a pouch with a similar shape.

Furthermore, in order to stack the above-mentioned wrapping or paper on the above-mentioned aluminum foil pouch, the wrapping or paper is supplied along one side of the outside of the above-mentioned arm μ, and is wound around the four sides of the arm μ in the same manner as above to form a cylindrical shape. Then, one end of the cylindrical shape is folded over the bottom edge of the aluminum foil to form a bag shape. As a result, a double pouch is produced.

Further, a cigarette supply means is disposed at a fixed position outside the upper turret. After the cigarettes are processed, they are arranged into bundles of 20, ie, three stacked bundles of 7, 6, and 7 cigarettes. The machine is equipped with a feeding device for inserting the bundle of cigarettes into the hollow cylinder of the arm.

Usually, the above-mentioned arbor tare device is provided with a gluing means, and the gluing means is used to glue the wrapping or paper to the necessary parts of the overlapping portion of the cylindrical pouch. Furthermore, if necessary, a heating device and a cooling device are installed, and necessary gluing and fixing are performed.

The cigarette is taken out from the arbor at a predetermined position of the arbor. At this time, a pusher is inserted from the opening end of the cigarette bundle, and the pusher is brought into contact with the end face of the bundle of cigarettes and pushed out. The cigarette is then inserted into the pouch, which has a bottom formed at the other end and is wound around the outside of the arm, and is simultaneously discharged from the arm as a packet. However,
As mentioned above, the upper end of the package is still open, and the necessary folding and sealing will be performed in the next step.

In the above packaging machine, aluminum foil and wrapping paper are supplied to the outside of the arm, and when being wound around this to make a pouch, the supplied wrapping paper is received on the side of the arm and held correctly. This is even more important. Particularly when wrapping multiple sheets of wrapping paper in layers, the suitability of the holding means has a critical effect on the quality of the finished product.

To this end, proposals have been made regarding the above-mentioned wrapping paper holding device, but problems have been pointed out with the known device.

That is, a rectangular holding plate disposed on two sides of the outer surface of the nine arbor and facing the holding plate, a lever device provided at one end of the holding plate, and a lever device for actuating the lever device, that is, the holding plate. A plurality of sets of pusher devices configured to swing pushers back and forth for opening and closing the pusher from a direction perpendicular to the rotating surface of the arboret, and a cam device that is connected to the pusher device to operate the pusher. By operating the pusher back and forth, the lever device is displaced, thereby opening and closing the presser plate. This is how the wrapping paper is received and held in the Arno (arno), and it also holds the overlapped parts of both ends.0 Since double wrapping of aluminum foil and paper is usually done, the entire cycle of the arboret is carried out. When the presser plate is opened and closed at multiple locations during rotation, the same number of sets of pusher devices as the number of opening and closing locations are required. , the above-mentioned small production process of wrapping paper with Arno as the core is not covered, and the field of view for inspecting and monitoring the receiving, holding and forming conditions of the wrapping paper is narrowed, and in some cases, it becomes impossible to monitor. As a result, the workability in terms of machine operation and adjustment was significantly reduced, which was a hindrance to stabilizing the operating efficiency of the machine.

Furthermore, the periphery of the arboret is contacted by the element member,
The equipment was complicated and had poor maintenance performance. In addition, when a plurality of presser plate opening/closing points are scattered, or when the opening size and opening/closing time are different, the same number of power sources as the number of opening/closing points, that is, the above cam device and the above cam device and the above Since members for connecting the pusher devices, such as cam levers and links, are required, the installation space increases, and it is not possible to combine them into a compact device.

Therefore, the same number of parts having the same shape as the number of opening/closing parts of the presser plate is required, and the number of parts constituting the entire device also increases, making the device relatively expensive.

In view of the above, one of the principal objects of the present invention is to provide a new type of device for retaining the overlapping edges of circumferentially wrapped wrapping paper.

Another object of the invention is to provide a new type of apparatus for receiving and retaining wrapping paper fed along one side of the outside of the arc.

According to the present invention and its main features, a presser plate facing the surface of the arm μ, a lever device provided at one end of the presser plate, a disk cam for operating the lever device, and a disk cam configured to move the disk cam to a predetermined position. It is equipped with a swinging device that allows it to reciprocate in angle. The disc cam is mounted coaxially with the arboret, and ridges are provided on the disc surface at predetermined positions. The arboret is stepped by intermittent rotation at intervals of the arμ arrangement, and the mountain-like protuberances of the cam are provided corresponding to the -steps. The above-mentioned rocking of the disk cam means rocking of one step advance angle. That is, the disc cam opens and closes the presser plate to receive and hold the wrapping paper while moving one step forward and backward.1. Next, take a step forward with the arborette. Incidentally, during the intermittent forward rotation described above, the arboret is stopped while the disk cam is rotated backward. and,
During the stop, the wrapping paper is inserted, the cigarette bundle is inserted, the required wrapping paper is folded, and the cigarette packet is discharged.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a schematic process diagram of a cigarette packaging machine in which the apparatus of the present invention is implemented. First, each process that makes up the machine will be explained.

It has a towered exit. At the outlet, the cigarettes are extracted as 20 bundles 3 of 7, 6 and 7 cigarettes, which are formed in a bucket) 4a.

In the figure, an example is shown in which two outlets are provided and the buckets 4a are used alternately.

The packets 4a are constituted by an endless packet conveyor device 4, and the packets 4a are conveyed intermittently in the direction of the arrow shown in the figure, one pitch at a time, by the operation of the machine.

When bucket) 4a reaches the tip, remove cigarette bundle 3.

The compressing turret 5 has a bucket 5a for accommodating the cigarette bundle 3, and compresses the cigarette bundle 3 slightly from all sides. This serves to facilitate insertion into AR μ6, which will be described later.

The arm turret 9 has the arm μ6 disposed around its periphery. In the illustrated example, 12 AR μ6 are arranged at equal intervals.

As shown in the figure, aluminum foil 7 of a predetermined thickness is supplied from the aluminum foil supply device 1o along the outer surface of the arm μ6 in the forward direction of rotation, and is wound around the outer periphery of the arm μ6′. The arboret 9 only rotates intermittently in the clockwise direction in the drawing, as indicated by the arrow in the figure.

When the arm μ6 is in the forward position, the paper 8
is supplied from the wrapping paper supply device 11 along the outer surface of the arm μ6 in the forward direction of rotation, and is wound around the outer periphery of the arm μ6. At this time, since the aluminum foil 7 mentioned above has already been wound around the arm μ 6, by winding the package or the paper 8,
A double pouch consisting of aluminum foil 7 and wrapping paper 8 is formed.

After the aluminum foil 7 is supplied to the arm μ6, it is wound around the arm μ6 to form a cylindrical shape as described above while the arboret 9 is rotating, and is bent at one end face of the edge of the arm μ6. It is formed into a pouch with a bottom surface. Similarly, the wrapping paper 8 supplied on the surface of the aluminum foil 70 is also
The cylindrical shape and bottom surface are bent to form the double pouch.

Glue material is applied in advance to predetermined positions on the wrapping paper 8, and gluing is performed by the winding and folding. In addition, a heater and a cooler are arranged in the subsequent rotation path of the arborette 9 to ensure the above-mentioned attachment.

On the other hand, while the arboret 9 is rotating, the cigarette bundle 3 is inserted from the compressing turret 5 into the opening of the other end face of the arm 6.

The small bag is wrapped around the outer periphery of the arm μ 6, the cigarette bundle 3 is built into the opening, and when it is rotated forward to a predetermined position, at the transfer position to the folding turret 12, from the open end of the cigarette bundle 3. , is pushed out to the other end face by a pusher through the opening of the arm μ6.

While the cigarette bundle 3 is being inserted into the pouch, it escapes from the arm 6 together with the pouch and is inserted into the opening of the folding turret 12.

Next, the arboret 9 will be described in more detail with reference to FIGS. 2 and 3.

Disc cams 18 and 19 are provided, respectively, in order to operate the presser plates 16 and 17 via lever devices to open and close them between the wide sides 6a and 6b.

The disk cam 18 has mountain-like protuberances 18a to 18f,
It is rotatably provided co-rotating with the intermittent rotating shaft 15a of the turret base plate 14, and operates the presser plate 16. Similarly, the disk cam 19 has a mountain-like protuberance 19a'f, and is rotatably provided coaxially with the intermittent rotating shaft 15a, and operates the presser plate 17.

Each of the disk cams 18 and 19 repeats backward and forward rotations of 30 degrees in accordance with the step angle of the turret board 14, and can be switched one after another following the forward movement of the arm μ6. .

Here, the packaging process when the turret substrate 14 rotates once will be described.

As mentioned above, when the turret board 14 rotates once, 1
There are two stopping positions. It is convenient to follow the clock face to indicate the position, so at 012 o'clock, which is indicated by the number enclosed in a circle on the drawing, aluminum foil 7 of a predetermined thickness is placed on the wide side of the arm μ6. 6a and held by the presser plate 16. Next, during the movement until 1 o'clock, the aluminum foil 7 is folded into a U-shape using the arm μ6 as a core material.The rotation path of the arm μ6 at this time is surrounded by both side walls, and the aluminum foil 7 is At 01 o'clock, the aluminum foil 7 extending from both sides of the arm μ 6 attempts to remain along the side wall, thereby achieving the U-half fold. reciprocates alternately from left and right along the rear side surface 6b of the arm μ6, tensions the U-shaped fold of the aluminum foil 7, and
Fold both edges of. The folded portion is then held on the rear side of the arm μ6 by closing the presser plate 17. In other words, the aluminum foil 7 is wound around the four side surfaces of the arm 6 to form a cylindrical shape.

Next, at 2 o'clock, the aluminum foil end piece extending from the surface 6b is moved with a folding claw, and then the aluminum foil end piece extending from the 6a side is moved by the folding guide provided on the side of the rotation path until 3 o'clock. are folded in respectively. Through the folding described above, a pouch is formed, although it is not complete, and the bottom surface is formed on the edge of one end face of the arm μ6.

At 3 o'clock, the cigarette bundle 3 is inserted from the compression turret 5 into the hollow cylinder of the arm μ6. At the same time, a packet or paper 8 of a predetermined thickness is received on the wide side surface 6a of the arm μ6, and the presser plate 16 is retained. Then, during the movement up to 4 o'clock, the wrapping paper 8 is folded into an L-shape along the narrow side 6c of the arm 6. At this time, a side wall is provided on the side of the rotation path of the arm μ6 facing the above 6c, and along the side wall, the wrapping paper 8 extending to the side of the arm μ6 is folded onto the above 6c surface. At 04 o'clock, the envelope extending on the 60th surface folds the paper 8 along the wide side surface 6b of the arc 6 with a folding claw, and the leading edge folds the paper 8 along the other narrow side surface 6d of the arc 6 with the folding claw.
Folded onto the surface. At this time, the paper 8 is the wide side 6b.
When stretched upward, the aluminum foil 7 is further stacked on top of the stacked aluminum foil 7. Here, the above presser plate 17
are opened and closed to receive and hold these wrapping papers. Then, during the movement up to 5 o'clock, the other overhanging edge of the wrapping paper 8 from the arm μ6 is folded into an L-shape along the narrow side 6d of the arm μ6; It will overlap exactly on the turned edge. Then, wrapping paper 8 is further wound around the aluminum foil 7 around the aluminum foil 7 to form a cylindrical shape.

At 5 o'clock, the bottom of the cylindrical package or sheet is formed. Place the aluminum foil 7 on the edge of the arm μ6.
Similarly to the bottom surface formation, it is also possible to overlap and fold the aluminum foil 7 at the same time as necessary. In this way, a double pouch is prepared in which the bottom surface of the pouch is formed on one end face of the pouch 6, and the pouch is covered with the pouch 6.

It is advantageous to apply hot-melt adhesive to the necessary portions of the wrapper paper 8 before feeding it at the 3 o'clock position.

The above-mentioned required bonding points of the pouch using the wrapping paper 8 are heated by a heater installed between the position past 5 o'clock and the position 7 o'clock, and then heated by the heater installed between the position past 7 o'clock and the position 9 o'clock. Cooling in a cooler activates and solidifies the hot melt to ensure adhesion.

At 11 o'clock, the cigarette bundle 3 housed in the hollow cylinder of the arm μ6 is extruded. When the cigarette bundle 3 is pushed out from the open end of the arm μ 6 toward the bottom surface of the pouch by the pusher, the cigarette bundle 3 is inserted into the double pouch exposed from the aluminum foil 7 and wrapping paper 8. The parcel product containing the is inserted into the folding turret 12 for the next process.

As seen in the above process, the arboret 9 is 1
During rotation, the wrapping paper holding device plays an important role. In other words, the aluminum foil 7, wrapping paper 8, etc.
is accepted into ARμ6 and held. Moreover, the suitability of the function of holding the folded portions of both ends of the wrapping paper wound on the outside of the arm μ6 immediately has a fatal effect on the quality of the finished product.

Next, the wrapping paper presser/apparatus which forms the main part of the present invention will be explained with reference to FIGS. 4 and 5. The presser plates 16 and 17 installed as shown in FIG. 1 will be explained, including their lever devices.

The holding plate 17 can be moved parallel to the arbor 6 and opened. Note that rubber plates 16a and 17a are attached to the presser plates 16 and 17, respectively, to prevent slipping and to prevent the aluminum foil 7 and wrapping paper 8 from being wound around the arbor 6 under tension. and to prevent damage to packaging materials.

Next, referring to FIG. 3, the opening/closing device for the presser plates 16 and 17 will be described.

First, the turret base plate 14 is transmitted from the output shaft of the intermittent indexing device 15, that is, the turret intermittent rotation shaft 15a,
The substrate 14 rotates by stopping at each of 122 stop positions provided on the rotational circumference of the substrate 14. A swing cylinder 41 is rotatably pivoted coaxially with the turret intermittent rotating shaft 15a, and disk cams 18 and 19 are fixedly provided at one end of the swing cylinder 41. The disk cams 18 and 19 are connected to the swing cylinder 41.
It swings and rotates in the forward and backward directions by swing transmission means, which will be described later, connected to the other end. The angle of the above rocking rotation is

This corresponds to the interval between the stop positions of the board 14 and one step.

The disc cams 18 and 19 have mountain-like ridges 18a and 19a at positions on the disc cams corresponding to the positions where the presser plates 16 and 17 are required to open and close, respectively, among the stopping positions of the turret base plate 14. are provided for each.

The surface of the mountain-like protuberance 18a of the disk cam 18 comes into contact with a cam follower 22 provided at one end of the lever device of the presser plate 16. Similarly, the mountain-like protuberance 19a of the other disc cam 19
The surface is brought into contact with a cam follower 31 which actuates the holding plate 17. Therefore, by rotating the two disc cams 18 and 19 in the forward and reverse directions around the intermittent rotating shaft 15a,
The cam follower 22 rolls along the surface of the Yamabushi ridge 18a and displaces the cam lever 23 to open and close the presser plate 16. Similarly, the cam follower 31 rolls along the surface of the Yamabushi ridge 19a and moves the cam lever 23 to open and close the holding plate 16. The cam lever 32 is displaced to open and close the presser plate 17.

To further understand the operation of the presser plates 16 and 17 in this embodiment, In order to do so, the explanation will be made with reference to No. 6.

In FIG. 6, the respective cam surfaces of the mountain-like protuberances 18a and 19a arranged on the disc cams 18 and 19 are shown in a developed manner, with the cam surfaces separated by the intervals between the stop positions of the turret base plate 14. The numbers surrounded by circles indicate the position of the clock face described in FIG.

The disc cam 18 has mountain-like protuberances 18a formed between 2 o'clock and 4 o'clock and between 10 o'clock and 1 o'clock.

The rising position and falling position of the mountain-like protuberance 18a, its inclination angle, and the height of the mountain are selected based on the necessity of operation of the presser plate 16, as shown in the illustrated example. The other disk cam 19 operates between 4 o'clock and 5 o'clock and between 10 o'clock and 2 o'clock.
A mountain-like ridge 19a is formed over time. The cam shape is selected based on the necessity of operation of the holding plate 17, as described above.

In particular, in the disc cam 18, there is a difference in the height of the peaks formed at two locations, and in the disc cam 19, the peaks starting at 10 o'clock are formed in two stages. Also, disc cam 19, 2
A steep inclination is seen in the fall before the hour, the rise and fall between 4 o'clock and 5 o'clock, and the fall of the disk cam 18 before 1 o'clock and the fall before 4 o'clock. That is, the presser plate is suddenly closed or opened, respectively.

Next, driving of the disk cam will be explained with reference to FIGS. 3 and 7.

A rotating shaft 4 that continuously rotates in one direction in synchronization with the packaging machine
A cam 43 is provided on the top of the cam 43, which is arranged so that it rises at 16 o'clock on the circumference and descends at 23 o0 on the circumference, and is supported by a shaft 4-1 provided parallel to the rotation axis 42 and can swing freely. A cam lever 46 is provided at its tip with a cam follower 45 in contact with the cam 43. The lever 17 is also fixed to the swing shaft 44! The rod 5 (N) is connected to the cam 4 through the pin 51 at the other end.
3 moves the rod 50 up and down. For the vertical movement of the rod 50, a spring can be stretched over the return movement on the cam surface 43, but in the illustrated embodiment, a cam is additionally provided for the return movement. 43' is provided.

That is, a cam 43' is provided on the rotating shaft 42 with a required angular phase shift, and a cam lever 46' that supports a cam follower 45' that comes into contact with the cam 43' is provided on the swing shaft 44.

The other end of the rod 50 is connected to a lever 48 via a pin 52f, and the lever 48 is fixed to the swing cylinder 41. The disk cams 18 and 19 are attached to the other end of the swing cylinder 41. The 049 mentioned above is a spherical joint.

Thus, the disc cams 18 and 19 are connected to the cam 43.
Due to the rotation of the cam 43, it is also 130° out of one rotation of the cam 43.
30° along the rotation direction of the turret substrate 140 in a time of
It rotates forward 30 degrees in the remaining time of 230 degrees. In other words, the period of the forward and reverse movement of the disc cams 18 and 19 is synchronized with the period of intermittent rotation of the turret base plate 14, and when the turret base plate 14 rotates, It rotates normally together with the turret board 14. Then, while the turret base plate 14 is stopped, the one-disc cams 18 and 19 reversely rotate through 30 degrees. As can be seen from this, the presser plates 16 and 17 are opened or closed, or opened and closed, while the turret base plate 14 is stopped, that is, within the above-mentioned time period 2300 of one cycle of the packaging machine. Then, for a period of 130°, the normal rotation is performed. At this time, presser plates 16 and 1
7 maintains an open or closed state.

For example, with reference to FIG. 8, the opening and closing operation of the presser plate 17 at 4 o'clock will be described.

FIG. 8 shows the disk cam 19, the cam lever 32, and the cam follower 31. In addition, the 3 o'clock and 5 o'clock positions are expanded and displayed with the 4 o'clock position as the center, and the movement of the disc cam 19 and the cam lever 32 during the time from when the disc cam 19 starts rotating in reverse until it rotates forward is shown. , divided into appropriate chronological order and illustrated.

First, in figure A, the turret board 14 stops at the 4 o'clock position,
This represents the point in time when the disk cam 19 begins to rotate backward.

The ridge 19a is located between 4 o'clock and 5 o'clock when viewed from the cam follower 31 position.

When the disk cam 19 starts to rotate in reverse, the presser plate 17 at the 4 o'clock position
The cam follower 31 extending from the disc cam protrusion 19a
rises along an open slope. The state during the ascent is shown in Figure B.

In FIG. 0, the cam follower 31 is located at the top of the protuberance 19a, indicating the fully open point of the presser plate 17.

The state in which the cam follower 31 is descending along the closed slope is shown in Fig. D. The press plate 17 is in the process of closing.

Figure E shows the cam follower 31 having climbed over the protuberance 31, that is, just before the turret substrate 14 has completed its 30° reversal. The press plate 17 is closed.

The disc cam 19 which has completed the above 30° reversal is then rotated to 30°.
°Rotate forward. At this time, the turret substrate 14 rotates forward by 30 degrees. Therefore, cam follower 31 protuberance 1
There is no relative movement with 9a, and both rotate in the normal direction. F this
Shown in the figure.

As described in the paper, the presser plate according to the present invention uses a disc cam device mounted on the intermittent rotating shaft of the turret, rotates the disc cam forward and backward, and utilizes the cam surface provided on the ridge of the turret. When the presser plate needs to open and close not only at one location but at multiple locations during one rotation of the turret, this can be handled by arranging the cam protuberances required for the number of opening and closing locations. Therefore, regardless of the number of opening/closing parts of the presser plate, or the increase or decrease in the number of wrapping paper stacks, the opening/closing device remains constant and can be adjusted only by adding or subtracting a slight protuberance. It is simple.

Furthermore, as shown in Fig. 3, the disk cam is located in the turret internal space, so the front part of the turret is open at 7, and the packaging process using the arbor as the core material can be seen sufficiently, and the machine is operated. It is easy for workers to inspect and monitor the receiving, holding, and forming conditions of the wrapping paper, and to approach it when necessary.

Furthermore, even if the opening amount and opening time of the plurality of presser plate opening/closing points are different, the height and shape of the mountain-like protuberance of the disc cam can be freely selected, and the There is no need to change the operating mechanism itself.

As described above, the apparatus is compact and has a small number of constant parts, which is advantageous in terms of maintenance.
