Abstract

PURPOSE:To provide a deep drawing type packing device by which an article is produced and packed from first to last. CONSTITUTION:Sliced hams produced by a slicer and transferred on a conveyor 8 are fed to a pocket of the lower film 13 on a deep drawing type packing device body 10 by a feeder 9. The lower film is drawn continuously from a material film 12 set in a film supply 11. And it is fed after it has been hooked on the first fixed roller, the idle roller, and the second fixed roller in this order. When the material film is consumed, a film is drawn from a preparatory material film into the lower side feeding film and stuck by use of a pressure-sensitive adhesive tape. At that time, the film is stopped drawing and pressed for a certain time interval and hence, it is securely stuck. And both films are relatively positioned by transferring the idle roller to a specified direction and reducing the distance between the first and second fixed rollers.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deep-drawing type packaging device, and more particularly to a packaging device constructed as a series of systems capable of consistently performing the process from the manufacture of a packaged product to the packaging.

[0002]

2. Description of the Related Art For example, when manufacturing a package in which sliced hams laminated in a predetermined number are hermetically housed, it is desired to continuously perform the process from the production of the sliced hams (object to be packaged) to the packaging by a series of systems. There is a request. In such a case, first, a ham slicer is cut into a predetermined thickness by a ham slicer, and a predetermined number of sheets are laminated, and the sliced ham in the laminated state is conveyed. Then, it is necessary to provide a transport device that performs a predetermined sorting process during the transport to align the n rows.

On the other hand, to package such sliced ham,
Generally, using a deep-drawing type packaging device main body, a pocket portion is formed at a predetermined portion of the lower film, the sliced ham in the laminated state is supplied into the pocket portion, the upper opening portion is covered with an upper film, and vacuum treatment is performed. Meanwhile, a predetermined part is sealed and cut.

In the body of the deep-drawing type packaging device,
Since the formation of pockets, the vacuum treatment in the pockets in the vacuum chamber, the heat sealing treatment between the films, etc. are performed collectively for each of the front and rear two rows, the packaging device should be driven intermittently at a distance of the front and rear two rows. become.

Therefore, in order to configure the above-mentioned series of systems, the laminated sliced hams conveyed in n rows laterally on the conveying apparatus are picked up every n × 2 rows from the beginning and the predetermined position of the packaging apparatus. More specifically, it is necessary to supply into each pocket portion at the same timing as the intermittent driving. As such an automatic supply device, for example, there is a device disclosed in Japanese Patent Publication No. 58-24332.

In such a device, a predetermined number (n × 2) of a pair of catcher claws for sandwiching the laminated sliced hams from the front and back are prepared, and the predetermined positional relationship (corresponding to the positional relationship of the pocket portions) is provided. The pair of catcher claws are driven to open and close, support the peripheral edge of the bottom surface of the sliced ham when closed, and lose the supporting force when opened to drop the sliced ham.

Then, each device is installed below the carry-out end side of the slice ham transport device having a horizontal transport surface so that the lower film can be transported in parallel at a predetermined distance. The claws are arranged so as to move back and forth between the carry-out end side of the transport device for the sliced ham and the upper side of the lower film.

As a result, first, each catcher claw supports the lower surface peripheral edge of the (n × 2) slice hams located at the leading end of the transport device, and in that state, the catcher claws rise once and move to the upper side of the lower film. , And then descend to position the catcher pawl just above the corresponding pocket. When the catcher claw is opened in this state, the supporting force is lost, so that each sliced ham naturally falls and is stored and supplied in the pocket portion.

[0009]

By the way, as described above, when the articles to be packaged (sliced ham) are manufactured, distributed and conveyed, and deep-drawn, there are various problems as described below. That is, first, in the part of the article supply device,
Due to the long movement distance of the catcher claw in the horizontal direction and the relationship of the movement locus, there is a limit to the speedup. That is, in the conventional system, the processing capacity of the automatic supply device was higher than the processing capacity of the other equipment such as the vacuum chamber, but in recent years it cannot be used for improving other equipment such as the vacuum chamber.
Improved processing capacity. As a result, the throughput (8-10 reciprocations / minute) of the automatic feeder was the lowest in the system. Therefore, it is necessary to increase the speed of the automatic supply device in order to improve the processing capacity of the entire system.

When the raw film for the upper and lower films for moving the deep-drawing type packaging device main body is used up, it is necessary to stop the packaging device main body once in order to supply the film from the next raw film. was there. In addition, such a temporary stop not only causes a decrease in the operating efficiency of the entire system, but also the replacement and the setting process of the original film are complicated, and if the film is set again like this, A large number of empty bags will be manufactured over a relatively long time from the beginning of and will be discarded in vain.

Further, since it is not possible to stop the product manufacturing line such as a ham slicer even during such replacement, a device for temporarily storing the manufactured sliced ham is required, and the capacity that can be stored by such a device is required. Also requires a large one (increasing the installation area) or discarding sliced ham produced at that time (useless use of raw materials)
There are problems in both cases.

On the other hand, in the case of the pillow packaging device, a stock film for backup is provided in addition to the stock film in use, and when the stock film currently in use is gone, the strip-shaped film pulled out. There is a device called a film supply, which connects the leading end of a strip-shaped film drawn from a preliminary raw film to the rear end thereof and enables continuous feeding of the strip-shaped film to the packaging device main body side. Therefore, it is conceivable to apply such a film supply to the deep-drawing type packaging device according to the present invention.

However, as compared with the film used in the pillow packaging device, the film used in the deep-drawing type packaging device which is the subject of the present invention (particularly the lower film in which the pocket portion is formed) is thicker, so that the film can be formed easily in a short time. It is not possible to bond films to each other. Therefore, the above film supply cannot be simply applied. This is also apparent from the fact that the film supply for pillow packaging machines has been used for many years, but the film supply for deep drawing packaging machines has not been developed.

The present invention has been made in view of the above background, and an object of the present invention is to rapidly and surely feed a continuously conveyed article to be packaged to a predetermined position of an intermittently moving lower film. It is also possible to supply the lower and upper films continuously (even when the original film is used up, it is automatically connected from the spare original film at the correct position to ensure the connection). As a result, it is possible to construct a series of systems from the manufacture to the packaging of the objects to be packaged, and to provide a deep-drawing type packaging apparatus that can reduce the installation area of such systems and improve the manufacturing efficiency. To do. Furthermore, as another purpose, the package manufactured as described above is accumulated in a predetermined number to produce a collective package, or a predetermined number of desired collective packages are packaged in a box. It is an object of the present invention to provide a deep-drawing type packaging device that can be stacked and stacked in order to achieve this.

[0015]

In order to achieve the above-mentioned object, in a deep-drawing type packaging apparatus according to the present invention, a manufacturing apparatus for manufacturing an article to be packaged and a manufacturing apparatus arranged downstream of the manufacturing apparatus are provided. A transporting means for transporting the packaged object, and a lower film that is arranged on the downstream side of the transporting device and receives the packaged object to be transported and is transported on the deep drawing type packaging device main body of the next stage. An article supply device for supplying the inside of the pocket portion, and a film supply means for supplying the lower film and the upper film to the main body of the deep-drawing type packaging device, wherein the film supply means rolls up the film to be supplied. A film, a support means for rotatably mounting a preliminary raw film, and a film for feeding the preliminary raw film before the completion of the film feeding from the raw film. A joining means for adhering and integrating the leading end of the film pulled out from the first fixing roller, a first fixing roller and a second fixing roller arranged at a predetermined position on the discharge side, and movably arranged between the both fixing rollers. An idle roller for adjusting the moving distance of the film from the first fixed roller to the second fixed roller, wherein the joining means temporarily stops the film that is intermittently transferred on the deep-drawing type packaging apparatus main body. While idle, it is set to perform a predetermined process, and the idle roller is moved in a predetermined direction in order to adjust the relative position of the two films to be joined.

Preferably, it is premised that the transfer surface of the lower film is located below the transfer surface of the transfer device by a predetermined distance, and the supply device is on the discharge side of the transfer device. An auxiliary conveying means having a downwardly inclined conveying surface provided, a swing center having a rotation center at a predetermined position above the auxiliary conveying means and the body of the deep-drawing type packaging device, and rotating forward and backward within a predetermined angle range. A moving member, a holding unit movably arranged below the swinging member, for temporarily holding the article to be packaged, a unit for rotating the swinging member forward and backward, and the holding unit for assisting the holding unit. A moving driving means for moving the feeding means forward and backward with respect to the supply surface of the packaging device, and the moving driving means is more than a moving distance of the holding means at an acquisition position for receiving the object to be packaged, Deep drawing type packaging Is to ensure that a longer moving distance of the holding means in the article supply position on the body.

Further, a stacking device which is arranged on the carry-out side of the deep-drawing type packaging device body and stacks a predetermined number of the manufactured packaging bodies in a state where the centers thereof are offset from each other, and is arranged on the downstream side of the stacking device. It is more preferable to provide a seal tensioning machine that seals and integrates the seals so as to extend over a plurality of laminated packages. Then, in such a case, the stacking device is manufactured by the deep-drawing type packaging device main body, and conveyor means that advances in the same direction as the arrangement direction of a plurality of packages that are carried out in a state of being aligned in a horizontal row, and the plurality of When transferring the package of the above on the conveyor means, comprising a transfer means for shifting the timing in order from the upstream side of the conveyor means, and, on the transport surface of the conveyor means, among the plurality of packages. A first step portion having an inclined surface for receiving the pocket portion of the package to be transferred first, and a pocket portion of each of the package bodies arranged at an appropriate position at a predetermined distance downstream from the first step portion. It is advisable to have a predetermined number of steps that are locked to the side surface of the.

It is more preferable to further provide a box packing means for aligning and packing the collective package into the box body on the downstream side of the sealing machine.

[0019]

The objects to be packaged manufactured by the manufacturing apparatus are sequentially carried on the carrying means. Then, when the unloading form in the manufacturing apparatus is one column in the vertical direction, the sorting process is appropriately performed in the transporting means, and a predetermined number of rows are converted into a state in which they are arranged side by side. And
When such an article to be packed comes to the carry-out side of the conveying means, it is received by the article supply device in a predetermined number and supplied to a predetermined position on the next deep-drawing type packaging device body, that is, in the pocket portion of the lower film. It After that, a normal deep-drawing packaging process is performed, the upper side of the lower film is covered with the upper film, and a predetermined position is sealed and cut to manufacture individual packages.

By the way, both the lower film and the upper film are pulled out from the original film and supplied to the main body of the packaging apparatus. However, when the original film currently being supplied is exhausted (used), It is possible to continuously supply it by shifting to the supply from the preliminary raw film. That is, basically, after the film currently being supplied, the tip of the film pulled out from the preliminary raw film is adhered (joined) with an adhesive tape or the like to be integrated,
Automatically (continuously), transfer to the film supply from the preliminary raw film.

When the two films are joined together, since the films are thick, it is necessary to keep pressing the films for a certain period of time in order to surely join the two films. Therefore, by utilizing the intermittent movement of the upper (lower) film on the body of the deep-drawing type packaging device, the joining means is operated while the film transfer is temporarily stopped, and the two films to be joined are joined together. And press it for a certain period of time. This ensures that both films are joined together to form one continuous film. On the other hand, generally, the upper film is subjected to predetermined printing for reasons such as a product display effect, and it is necessary to align the printed portion with a position corresponding to the pocket portion in which the object to be packaged is stored. Therefore, such alignment marks (referred to as eye marks) are formed on the side edge of the film at regular intervals. Therefore, it is necessary to match the eye mark of the film currently being supplied with the eye mark of the film connected thereto. Therefore, in the present invention, the idle roller is moved in a predetermined direction to feed the film which is being stopped and is being fed so that the alignment reference marks such as the eye marks of both films are aligned. Therefore, even when the film is switched from the preliminary material to the deep-drawing type packaging apparatus main body side thereafter, the relative positions of the eye marks and the like do not change, so that the packaging processing is continuously performed without readjustment.

Further, since the lower and upper films of the deep-drawing type packaging apparatus main body move intermittently, there are cases where the above-mentioned joining processing is performed and when the transfer of the film is temporarily stopped on the packaging apparatus main body side. Not necessarily the same. Therefore, when the film is transferred on the packaging device body side during the bonding process, that is, when the film needs to be supplied to the packaging device body side,
Film supply is performed by moving the idle roller in a predetermined direction to shorten the film length from the first fixed roller to the second fixed roller. The idle roller is moved in the opposite direction to the film supply to the packaging apparatus main body side at the time of the next film joining, while the film feeding is temporarily stopped in the packaging apparatus main body during normal operation.

In the case where the downward feeding auxiliary conveying means and the holding means movably provided below the swinging member swinging above it are used as the article supplying device, first, the auxiliary conveying means is used. The articles to be packaged are arranged at predetermined positions on the means at predetermined intervals, and the swinging member is positioned at one end of the rotation angle range and is stopped and waiting. In this state, the movement driving means is operated to move the holding means forward (downward) toward the auxiliary conveying means to contact the article and hold the article.

Then, after the holding means is lifted and separated from the auxiliary conveying means, the swinging member is rotated by a predetermined angle and positioned on the packaging device. Then, the holding force of the holding means is released and the article is dropped.However, in order to surely drop and supply the article to the predetermined position of the packaging device, the holding means is moved down again and moved to the vicinity of the supply surface of the packaging device. Let This completes the automatic supply.

As described above, since the place for receiving the article is on the auxiliary conveying means which is inclined, the holding means is rotated in the forward and reverse directions within the predetermined angle range with the upper end of the swinging member as the rotation reference. It can be located just above the receiving position and the supplying position of the article. That is, since it is possible to reciprocate between predetermined positions by rotational movement,
High-speed processing from the receipt of goods to the supply processing.
Moreover, the rotation angle is small.

Further, when the stacking device is provided on the downstream side of the packaging device body and the seal affixing machine is provided, the single package manufactured by the packaging device body is accumulated in a predetermined state by the stacking device, A sticker is applied in such a state that it is hung on a plurality of packages with a sticker pasting machine. As a result, the integrated packages are integrated to produce a collective package. That is, the steps from the manufacture of the packaged object to the manufacture of a collective package in which a plurality of individual packages produced by packaging the packaged object are collected are continuously performed.

Further, when a predetermined box packing means is arranged on the downstream side of the seal applying machine, the collective package manufactured as described above is further supplied into the box body in a predetermined number of aligned states, and the box is packed. The body is sealed. That is, from the manufacturing of the packaged object to the shipping, the packaging process is continuously performed using a series of systems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the deep-drawing type packaging device according to the present invention will be described in detail below with reference to the accompanying drawings. 1 to 6 show a preferred embodiment of the present invention, and in this example, because the number of devices constituting the system is large, they are shown separately. In addition, an example is shown in which sliced ham is used as the object to be packaged and the sliced ham is applied to an apparatus for vacuum packaging using a deep-drawing type vacuum packaging apparatus body.

As shown in the figure, a slicer 1, which is a manufacturing apparatus, is installed on the upstream side of the system. This slicer 1 clamps a raw wood 2 such as ham by a predetermined set of sandwiching conveyors 1a arranged upright, and intermittently drives the sandwiching conveyor 1a to move the raw wood 2 downward by a predetermined amount intermittently. Then, the lower end of the lowered raw wood 2 is cut by a rotating cutting blade (not shown) to produce sliced ham. Then, the sliced ham cut in this way falls by gravity, but a product receiving plate (not shown) is also arranged at the dropping position, and the sliced ham is placed on the product receiving plate. , Will be sequentially laminated. When the predetermined number of sheets are stacked, the carry-out conveyor 1
It is designed to be transferred to b.

By the way, in this example, a raw wood supply device 3 is provided further upstream of the slicer 1, and the sandwich conveyor 1a is provided.
The ham log 2 is automatically supplied to the ham. That is, as shown in FIGS. 1 and 4, the log supply device 3 can stock a plurality of logs 2 outside the front side of the main body 3a. Then, the most advanced log 2 is moved to the top surface 3b by the elevator mechanism and transferred onto the transport path 3c composed of a large number of rollers, and then the upstream end of the transport path 3c is lifted to incline the transport surface. Has become. Then, the log 2 slides down on the transport path 3c due to its own weight, and then the log 2 is inserted into the chute 3d having a path whose tip is curved downward. Then, the log 2 falls in the chute 3d, and the log 2 is supplied into the sandwiching conveyor 1b of the slicer 1.

On the other hand, a measuring device 4 is arranged downstream of the discharge conveyor 1b of the slicer 1. Then, while the sliced hams 5 carried out from the carry-out conveyor 1b and transferred onto the weighing device 4 and having a predetermined number of layers stacked thereon, the entire weight thereof is measured while moving on the weighing device 4, the sliced ham 5 falls within a predetermined range. Is checked. Then, from the weighing device 4, it is determined whether or not the sorting / sorting device 6 in the next stage is within a predetermined range (OK), and when it is out of the range, whether it is overweight or underweight. Is output.

The sliced ham 5 weighed by the weighing device 4 as described above is sent to the sorting and sorting device 6 in the next stage, where it is sorted and sorted in three horizontal rows. The sorting / distributing device 6 is also called a channelizer, and a large number of bars are attached between a pair of endless chains provided on both sides of the conveying path so as to extend in a direction orthogonal to the conveying direction. It is configured with a product support plate that is slidable on the bar. This product receiving plate is located at the center of the bar on the carry-in side (near the carry-out port of the weighing device 4), slides to an appropriate position during the carrying, and is located at the entrance of the next predetermined carrying path on the carrying-out side. Become.

As a result, the sliced ham 5 carried out from the weighing machine 4 is first placed on the article receiving plate, and is moved forward by the conveyance of the article receiving plate due to the rotation of the endless chain. Is moved in the horizontal direction as the slide No. 1 is moved and is transferred from the predetermined outlet to the pool conveyor 7 of the next stage. Then, the determination of the lateral movement position is
When the weight measured by the weighing device 4 is within the predetermined range, the three outlets (indicated by “OK” in FIG. 4) are sequentially selected to reach them, and the weight is overweight or insufficient. If there is one, it will be sent to either of the two outlets indicated by “NG” in FIG. 4 (divided by overweight and underweight).

In the pool conveyor 7 arranged further downstream of the sorting device 6, five conveyors are provided corresponding to the five outlets of the sorting device 6 (3 OK, 2 NG). The three transfer paths 7a to 7c, which have the paths 7a to 7e and are connected to the regular outlets, continue to the transfer device 8 of the next stage as they are. At this time, the speed is increased / decreased according to the processing condition on the downstream side, and three pieces are arranged side by side and transferred to the transfer device 8 at predetermined intervals.

The remaining two transport paths 7d and 7e are
The carry-out end is open, and the sliced ham having an inappropriate weight that is transported on the transport paths 7d and 7e is discarded as it is.

On the other hand, the carrying device 8 is composed of a large number of round belts having a carrying surface in the horizontal direction. An article supply device 9, which is one of the features of the present invention, is arranged on the carry-out end side of the carrying device 8.

Below the carry-out end of the carrying device 8,
A vacuum packaging device main body 10 having a conveyance direction in the same direction as the conveyance direction is arranged. That is, on the loading side of the main body 10 of the vacuum packaging device, a predetermined tension is applied from the original film 12 by the film supply 11 (which is arranged in the space below the transport device 8) which is one of the features of the present invention. The lower film 13 that is intermittently pulled out in the applied state and supplied onto the transport path of the vacuum packaging device body 10 is below the transport device 8 by a predetermined distance, and is also at the transport device 8.
It is arranged so as to be transported in the same direction as the transport direction of.
Further, a pocket 13a is formed at a predetermined position of the lower film 13 by a molding device 14 provided in the middle of the transportation (upstream of the article supply device 9).

Then, the sliced ham 5 conveyed on the conveyor 8 is supplied into the pocket portion 13a, and the upper film 16 is covered at a predetermined position X downstream of the supply position. Like the lower film 13, the upper film 16 is also supplied by the film supply 17.
It is intermittently pulled out from the original film 18 arranged thereon under a predetermined tension and guided to the predetermined position X by a plurality of pulleys 19.

Further, the upper and lower films 15 and 17
At the downstream side of the predetermined position X where the
Is disposed there, vacuum processing in the pocket portion 15a and sealing treatment of the contact portions of both films 15 and 17 are performed therein, and the cutting device 21 disposed further downstream thereof.
At 1, the package is manufactured one by one by appropriately cutting predetermined positions in the horizontal and vertical directions of the traveling direction.

The automatic article supply device 9 will be described here. As shown in an enlarged view in FIGS. 7 and 8, first, the first feature is that the leading end (delivery side) of the conveying device 8 is inclined downward. Of the auxiliary carrier 25, and the slice ham 5 moving on the carrier 8 is transferred onto the auxiliary carrier 25.
The slice ham 5 that has arrived on the auxiliary transport device 25 is gripped by the article supply device 9 and supplied to a predetermined position on the lower film 13. In this example, since a total of 6 slice hams 5 of 3 × 2 (horizontal × vertical (front and back)) are simultaneously supplied onto the lower film 13, the auxiliary transport device 2
The length of the sliced ham 5 is such that two sliced hams 5 are located at the front and rear with at least a predetermined interval.

Then, by the stopper means described later,
Six sliced hams 5 are temporarily stopped at a predetermined position on the auxiliary transporting device 25, and in this state, each sliced ham 5 is supported by a gripping portion 26 that is a holding means having a catcher claw that can be opened and closed. ing. This grip 26
Is attached to the lower end of the oscillating plate 27 having the upper end as a rotation axis (rotation center), and is movable forward and backward along the extending direction of the oscillating plate 27.

The oscillating plate 27 is connected to the other end of the operating rod 29, one end of which is connected to the eccentric position of the rotating plate 28, and the operating rod 29 linearly moves (the rod extends) as the rotating plate 28 rotates. (Moving forward and backward in the direction), it follows and swings like a pendulum. In other words, it reciprocates between the fixed position shown by the solid line in FIG. 8 and the supply position shown by the chain double-dashed line. Then, the swing plate 27 is
It is adjusted so that it is orthogonal to the transport surface of the auxiliary transport device 25 at the fixed position, and is orthogonal to the lower film 13 at the supply position. This is the second feature of the present invention.

By virtue of the above structure, first the swing plate 2
When 7 is at the position shown by the solid line in the figure, the gripping portion 26 grips (supports) the slice ham 5 on the auxiliary transporting device 25, and then the rotating plate 28 is rotated to rotate the rocking plate 27 by a predetermined angle. Position it in the state of the chain double-dashed line in the figure.

Then, the catcher claw of the grip portion 26 is opened to drop the supporting force, and the slice ham 5 is dropped to a predetermined position (the pocket portion 13a) of the lower film 13.
Supply). Thus, in this example, sliced ham 5
Since the position of receiving the slices is on the auxiliary transporting device 25 arranged in a slanted manner, the gripping part 26 is moved forward and backward in a predetermined angle range with the upper end of the rocking plate 27 as a rotation reference, so that the slice ham receiving position is received. And can be located just above the supply position. Therefore, since it is possible to reciprocate between the predetermined positions by the rotational movement, the processing can be performed at high speed. Moreover, since the rotation angle is small,
It will be faster.

However, in reality, since the sliced ham is rotated (rotated) from the position where the sliced ham is received (held), the sliced ham collides with the transport surface of the auxiliary transport device 25, so that each position moves up and down by a predetermined distance. That is, the swing plate 27
Is at the position indicated by the solid line in the figure, the catcher claw of the grip portion 26 is lowered to a predetermined position in an open state, and then the catcher claw is closed to support the slice ham 5 on the auxiliary transport device 25. Then, after the grip portion 26 is lifted, the rotating plate 28 is rotated to rotate the swing plate 27 by a predetermined angle, and is positioned in a two-dot chain line state in the figure. Thereafter, the grip portion 26 is lowered by a predetermined amount (for a reason to be described later, the grip portion 26 is moved more than the above movement), and then the catcher claw is opened to supply the article. After that, after raising the grip portion 26, the swing plate 27 is moved in the opposite direction to return to the standby position indicated by the solid line in the figure so as to be ready for the next article supply.

Next, a more detailed structure for performing each of the above processes will be described. First, the auxiliary transport device 2 described above
As shown in FIG. 9 and FIG. 10 in an enlarged scale, 5 is a large number of round belts 3 provided between the drive pulley 30 and the driven pulley 31.
2, and in this example, each transport path is configured by four round belts 32 (see FIG. 10). In addition, the driven pulley 31 includes a round belt 8 that constitutes the transport device 8.
a is also provided and is synchronously driven to rotate at the same speed. A fixed stopper 33 is disposed at a predetermined position on the tip of the auxiliary transporting device 10 so as to project above the transporting surface constituted by the round belt 32. As a result, the sliced hams 1 in the three horizontal rows conveyed on the auxiliary conveyance device 10 come into contact with the fixed stoppers 33, and further forward movement is suppressed and stopped.

Further, a movable stopper 34 is formed at a predetermined position on the upstream side of the fixed stopper 33. The movable stopper 34 is projected and retracted from the conveying surface at a predetermined timing. Specifically, one end of an inverted V-shaped swinging rod 34a is bent further upward to form a stopper portion 34b. And is rotatably attached to the rotary shaft 35 at an inverted bending point.

On the other hand, the operating rod 3 is provided at the other end of the swing rod 34a.
The lower end of 6 is attached. Furthermore, this operating rod 36
An upper end of the connecting rod 37 is connected to one end of the connecting rod 37, and the other end of the connecting rod 37 is fixed to the rotating shaft 38. The rotary shaft 38 is provided with a cylindrical body 40 fixed to the machine frame 39.
In contrast, the bearing portion 41 rotatably supports it. Further, the other end of the rotating shaft 38 projects outward from the machine frame 39, a connecting rod 42 is connected to the tip thereof, and the cylinder rod 4 of the air cylinder 43 is connected to the tip of the connecting rod 42.
3a is connected (see FIG. 11).

As a result, when the air cylinder 43 expands and contracts, the connecting rod 42 rotates forward and backward about the rotation shaft 38 at a predetermined angle. Therefore, the rotating shaft 38 also rotates forward and backward,
The rotational force is converted into a linear motion by the connecting rod 37, and the operating rod 36 moves up and down. Then, the swing rod 36 rotates forward and backward around the rotary shaft 35 accordingly, so that when the operating rod 36 moves downward, the stopper portion 34b rises and projects upward from the conveying surface (shown by the solid line in FIG. 9). , The slice ham 5 moving on the auxiliary transporting device 25 is locked, and further forward movement is suppressed and stopped. On the other hand, when the operating rod 36 moves upward, the stopper portion 34b descends and enters below the conveying surface (shown by a chain double-dashed line in FIG. 3), and allows the slice ham to be conveyed thereabove.

Next, the grip portion 26 and a device for moving the grip portion 26 along a predetermined locus will be described. As shown in FIGS. 11 and 12, the swing plate 27 to which the grip portion 26 is attached is rotated via the bearing portion 44 on the upper end of the machine frame 39 that is formed upright outside the both side edges of the lower film 13. It is fixed to a predetermined position of a rotary shaft 45 which is freely attached, and is configured to rotate forward and backward (swing) integrally with the rotary shaft 45 within a predetermined angle range.

Further, the rotary plate 28 has a drive motor 46.
Is connected to the output shaft 46a of the drive motor 46 and rotates following the rotation of the drive motor 46. Then, when the drive motor 46 rotates 180 degrees from a certain reference position, the drive motor 46 temporarily stops, and after a certain period of time, further rotates 180 degrees in the same direction and returns to the original position. In addition,
Of course, it is also possible to rotate in the forward and reverse directions at a predetermined angle.

The specific construction of the grip portion 26 is shown in FIG.
2, as shown in an enlarged manner in FIG. 13, with respect to the four rotary shafts 49 hung in parallel between both ends of the top plate 47 and the wall plates 48 vertically provided at predetermined positions on the lower surface, Three catcher claws 50 are fixed.

The catcher claw 50 has a bottom surface 50a whose lower end projects inward.
Can be grasped by entering the bottom of the sliced ham 5 and supporting it from below. Further, the bottom surface 50a is formed in a substantially fan shape in this example corresponding to the sliced ham 5, and the inner wall surface 50b is also formed in an arc shape accordingly, and the detachment of the sliced ham 5 is suppressed by the inner wall surface 50b. .

Next, as described above, the catcher claw 50
Will open and close at a predetermined timing to support the sliced ham 5, or release the supported sliced ham 5 and supply the sliced ham 5 to the packaging apparatus main body 10. The mechanism for opening and closing will be described. That is, first, a gear 51 is attached to one end of each of the rotating shafts 49, and the gears 51 attached to the rotating shafts 49, to which a pair of catcher claws 50 for supporting the slice ham 5 are attached, mesh with each other. (See Figure 13). Then, the predetermined gear 51
Is a plate member 5 having a U-shaped opening with a sufficiently long tip.
2 is fixed.

On the other hand, a forward / reverse rotatable motor 54 is attached to the auxiliary plate 53 connected to the top plate 47, the swing lever 54 is attached to the output shaft 54a of the motor 54, and the tip of the swing lever 54 is attached. Attach the cam floor 55 to. Then, the cam floor 55 is fitted into the notch 52a formed at the tip of the plate member 52.

As a result, when the motor 54 is normally or reversely rotated at a predetermined angle, the swing lever 24 is swung at a predetermined angle about the output shaft 54a. Then, the cam floor 55 is shown in FIG.
It reciprocates between a position indicated by a solid line and a position indicated by a two-dot chain line along an arcuate locus. With the reciprocating movement of the cam floor 55, the notch 52a of the plate member 52 which coincides with the reciprocating movement is also urged in the moving direction of the cam floor 55, and the plate member 52 swings with the rotating shaft 49 as a reference. Therefore, together with the plate member 52, the rotary shaft 4
9 is normally and reversely rotated within a predetermined angle range, and accordingly, the gear 51 fixed to the rotary shaft 49 is also normally and reversely rotated. Therefore, since the gears 51 connected by the gears 51 also rotate in the predetermined direction, as shown in the drawing, the open state of the catcher claw 50 and the closed state of the chain double-dashed line are alternately performed. become. As a result, the catcher claw 50 opens and closes. In the example shown,
Although the state in which the gear 51 is connected so as to mesh with the catcher pawl 50 on one side is shown, the same configuration is also provided on the side of the catcher pawl 50 that is the other pair. That is, all six sets of catcher claws 50 mounted on the grip portion 26 are adapted to open and close in synchronization.

Then, as described above, the catcher claw 50
When it moves with the slice ham 5 being supported and the catcher claw 50 is opened on the body 10 of the packaging device, the supporting force is lost and the product falls freely. However, in this example, the pusher is used to ensure more reliable fall. 56 are provided.

That is, the pusher 56 is provided on the top plate 4
A bolt 57 that can move up and down is provided so as to pass through 7, and a disc-shaped pressing plate 58 is attached to the lower end of the bolt 57. A first spring 59 is mounted between the head 57a of the bolt 57 and the top plate 47, and a second spring 60 is provided between the top plate 47 and the push plate 58. Then, in the unloaded state, as shown in FIG. 13, the push plate 58 is in a state of being stopped at a position near the lower portion of the catcher claw 50 to achieve balance (in this state, one of the springs 59 and 60 is compressed). By elastically deforming it, it can move either upward or downward). Although the pusher 56 is provided in the catcher claw 50 on one side in the illustrated example, the pusher 56 is, of course, disposed in all the catcher claws.

Next, a mechanism for moving the grip portion 26 up and down will be described. First, as shown in FIG. 11, the oscillating plates 27, 27 fastened and fixed to the rotary shaft 45 at a predetermined interval.
A strip-shaped bottom plate 61 is attached to the lower end of the. Then, first air cylinders 62, 62 are provided near both ends of the upper surface of the bottom plate 61. A moving plate 63 is attached to the tips of the cylinder rods 62a, 62a of the first air cylinders 62, 62, and the first air cylinder 6
The movable plate 63 also moves up and down as the second cylinder rod 62a expands and contracts.

Second air cylinders 64, 64 are attached downward at predetermined positions near both ends of the upper surface of the moving plate 63. That is, a through hole 63a is formed at the cylinder mounting position of the moving plate 63, and the cylinder rod 64a of the second air cylinder 64 is the through hole 63a.
It protrudes to the lower side of the moving plate 63 via.

Further, an extension rod 65 is attached to the tip of the cylinder rod 64a, and the extension rod 65 is inserted into the bearing sleeve 60 mounted in a predetermined position of the bottom plate 61 in a penetrating state to extend the extension rod 65. Of the bearing sleeve 60 is projected further downward than the lower end of the bearing sleeve 60, and is attached to the top plate 47 of the grip portion 26 described above. As a result, the grip portion 26 is moved to each air cylinder 6
It is hung and supported by the bottom plate 61, that is, the oscillating plate 27 via 2, 64.

The state shown in FIG.
Indicates the time just above the pocket 5a of the lower film 13 (the article supply position), that is, the time when the grip 26 has reached the lowest position, the cylinder rod 62a of the first air cylinder 62 is It contracts and enters the main body, and the cylinder rod 64a of the second air cylinder 64 is expanded.

Then, when the first air cylinder 62 and / or the second air cylinder 64 is operated to expand and contract the predetermined cylinder rods 62a, 64a, the cylinder rod 64a of the second air cylinder 64 will cause the bearing sleeve 60 to move.
The grip portion 26 also moves up and down because it moves forward and backward in the axial direction. That is, when the cylinder rod 62a of the first air cylinder 62 is extended and the cylinder rod 64a of the second air cylinder 64 is contracted (the opposite state of FIG. 11), the grip portion 26 is located at the uppermost position, Drive motor 4 at this position
6 is rotated to rotate the rocking plate 27 forward and backward.

When the sliced ham 5 on the auxiliary carrier 25 is gripped, the cylinder rod 62a of the first air cylinder 62 and the cylinder rod 64a of the second air cylinder 64 are both contracted to grip the gripping portion 27. Is performed at a predetermined position between the uppermost position and the lowermost position (determined by the difference in stroke of both cylinders).

Further, in this example, the third air cylinder 67 is attached downward at the center of the bottom plate 61. The cylinder rod 67a projects downward through a through hole 61a provided in the center of the bottom plate 61, and a flat plate-like biasing plate 68 is fixed to the tip thereof. This bias plate 68 is
Guide rods 69 are formed upright on both ends of the upper surface, and the guide rods 69 are inserted into guide sleeves 70 provided at corresponding predetermined positions of the bottom plate 61, and their vertical movement guides.

As a result, when the third air cylinder 61 operates, the urging plate 68 also moves down / up along with the expansion / contraction of the cylinder rod 61a. At this time, the guide rod 6
9 is a biasing plate 68 for sliding in the guide sleeve 70.
Will move in a stable state (maintaining a horizontal state). Then, when the urging plate 68 comes to the lowermost position, the head 57a of the bolt 57 that constitutes the pusher 56 is pushed down, whereby the pusher 56 is pushed.
The pushing plate 58 of the is lowered, and the sliced ham 5 is forcibly (reliably) dropped (see FIG. 14).

Next, the film supplies 11 and 17 will be described. Since the film supply 11 for the lower film and the film supply 18 for the upper film 17 are basically the same, the film supply 11 for the lower film 13 will be described.

First, as shown in an enlarged scale in FIGS. 15 to 17, the original film 12a in use and the original film 12b for backup are supported in parallel. Specifically, each of the original films 12a and 12b is inserted and arranged in a hollow cylindrical loading cylinder 71 which is a means for supporting the original film, and the base end side of the loading cylinder 71 is rotated on the side wall 72 in a free state. It is installed as possible. Then, by rotating the dial 71a provided at the tip of the loading cylinder 71 in a predetermined direction, the support plate 71b mounted in the loading cylinder 71 so as to be retractable and retractable protrudes from the outer peripheral surface, and the original film 12
By urging a and 12b in a predetermined direction, the loading cylinder 71
It is fixed to. As a result, when the tips of the original films 12a and 12b are urged in the pull-out direction,
The pulling force is transmitted to the original films 12a and 12b and tries to rotate, so that the loading cylinder 71 also rotates integrally.

On the base end side of the loading cylinder 71, the brake cylinder 73
Are integrally attached, and a band 74 is stretched around the brake cylinder 73. One end 74 a of the band 74 is fixed to the mounting plate 75, and the other end 7 a
4b is attached to one end of the L-shaped arm 76a. The L-shaped arm 76a is attached to the attachment plate 75 at its bending point so as to be rotatable in the forward and reverse directions within a predetermined angle range, and further, in the predetermined direction, that is, in the direction in which the band 74 is loosened by the helical spring 76b. Adjusted to be biased.

The other end of the L-shaped arm 76 (band 7
One end of the spring 77a is attached to the non-connection side end portion of 4. The other end of the spring 77a is attached to a predetermined position on the side surface of the arm 78. The arm 78 is mounted on the loading cylinder 71 via a bearing and is rotatable independently of the loading cylinder 71.
A spring 77b shown in the upper part of the figure connects between the other ends 78a, 78a of the arms 78, which are bent in an L shape, and the spring 77b constantly connects the other ends 77 to each other.
a is pulled and moves inward (toward the center), that is, the tip of the arm 78 rotates and moves upward in the drawing. Accordingly, the other end of the L-shaped arm 76a is pulled up by the spring 77a, the band 74 is tightened, the contact friction with the brake cylinder 73 increases, and the brake is applied. Then, the tip of the arm 78 is lowered by rotating the arm 78 in a direction opposite to the above by a drive source (not shown). Then, the band is loosened due to the action of the spiral spring 76b, which reduces the braking force.

On the other hand, a tension roller 79 is cantilevered and rotatably attached to the tip of the arm 78 (see FIG. 17), and the tension roller 79 is pulled out from the original films 12a and 12b. The lower film 5 is hung over. Note that FIG.
The arm 78 and the tension roller 79 in FIG.
It shows a state where the arm 78 is rotated 90 degrees from the position and the arm 78 is brought to a position where it is erected upward. (That is, the part is not exactly a front view of FIG. 15).

Further, the lower film 5 pulled out from the original films 12a and 12b, before being stretched over the tension roller 79, has a sensor 80 for detecting the end of the film,
After passing through the fixed roller 81a, its path is converted upward. And in this example, the lower film 1
When 3 is completely pulled out from the original films 12a and 12b (only the paper tube on which the film is wound remains on the original films 12 and 12b), a predetermined tension can be applied to the lower film 13. Since it is not possible, it is detected that the film has been wound a predetermined number of times around the paper tube, that is, the end of the film is approaching. Specifically, a detection tape or the like is attached to a predetermined position of the wound lower film, and the detection tape is detected by the sensor 80.

Further, the lower film 13 which has passed through the tension roller 79 has its path converted downward, and is stretched around a fixed roller 81b arranged at the lower position thereof to further convert the path horizontally. , Will proceed toward the center. The sensor 80 and each fixed roller 81
The a and 81b are attached to a horizontally extending auxiliary side wall 82 (this auxiliary side wall is fixed to the side wall 72).

A moving roller 83 is arranged at the central portion of the side wall 72 in the horizontal direction so as to come into contact with the lower surface of the lower film 13 moving in the horizontal direction.
This moving roller 83, as shown in FIGS.
In a normal state (when the lower film 13 is pulled out from the original film 12a and supplied to the main body of the packaging device),
They are arranged in parallel at a predetermined interval.

The moving rollers 83 move so as to approach each other at a predetermined timing, and the lower film 13 can be pinched between the moving rollers 83. As shown in FIG. 15, the moving mechanism has the moving roller 83 rotatably attached to one end of the L-shaped plate 90, and the gear portion 90a is provided at the other end of the L-shaped plate 90. Mesh with each other. And the bending point 9 of the L-shaped plate 90
0b is the center of rotation. Further, rods 91 are vertically provided at predetermined positions on the lower surface of the L-shaped plate 90, and the lower ends of both rods 91 are connected to both ends of a spring 92, respectively. The elastic restoring force of the spring 92 in the contracting direction constantly urges the rods 91 toward each other, that is, the moving roller 83 away from each other as shown in the drawing. Then, the rotational force of the drive motor 93 is transmitted to the L-shaped plate 90 via the transmission belt 94 and the like, and the L-shaped plate 90 is rotated in a predetermined direction (a direction in which the moving roller 83 approaches). Further, since the spring 92 is stretched during this rotation, when the rotation of the drive motor 93 is stopped, the elastic restoring force of the spring 92 returns to the state shown in FIG. 15 (from the drive motor 93 to the L-shaped plate 90). By inserting a one-way clutch or the like in the middle of the power transmission system, the drive motor 93 can be easily returned to the normal position by the spring 92 while using a simple drive motor 93 that rotates only in the same direction. In this example, the moving roller 83 and the L-shaped plate 90, the rod body 91, the spring 92, the drive motor 93, the transmission belt 94, and the like for moving them together constitute a joining means.

On the other hand, the lower film 13 is stretched over the moving roller 83 and the traveling direction thereof is converted downward,
Further, the lower film 13 has both moving rollers 83, 83.
A first fixed roller 84 disposed below the middle portion of the
The idle roller 85 is disposed obliquely upwardly from the first fixed roller 84 at a predetermined distance, and the second fixed roller is disposed obliquely upward from the idle roller 85 (direction returning to the first fixed roller 84 side). After being passed over the rollers 86 in this order, they are supplied to the packaging apparatus main body 10 side via a predetermined roller (see FIG. 2A etc.). That is, the first
The moving distance of the lower film 13 from the fixed roller 84 to the second fixed roller 86 is changed by moving the idle roller 85.

Further, in the present invention, both fixed rollers 84, 8
One of the features of the film supply is that an idle roller 85 that can move in the horizontal direction is provided between the rollers 6. In the mechanism for horizontally moving the idle roller 85, as shown in FIG. 15, the pinion 87a is mounted coaxially with the idle roller 85 in a free state (so that it can rotate independently of the idle roller 85). on the other hand,
The rack 87b that meshes with the pinion 87a is attached along the oblong guide hole 88a formed in the guide plate 88. Then, the rotating shaft 8 of the idle roller 85
5a is inserted into the guide hole 88a. Then, when the rotational force from a drive motor (not shown) is transmitted to the pinion 37a, the pinion 37a rotates forward and backward, and the rack 87b rotates.
Move back and forth along.

As a result, the distance from the first fixed roller 84 to the second fixed roller 86 changes, so that the idle roller 85 can be operated even when the film transfer is temporarily stopped on the packaging apparatus main body side. By moving in the predetermined direction, the film can be pulled out from the original film.

That is, since the film used for vacuum packaging is thick, when the next original film is bonded and integrated at the end of the film in use, the original films 12a, 1
The two films that were pulled out from the 2b were temporarily stopped, and the two films that were pulled out were clamped to keep the pressure for a long time so that they can be reliably bonded and integrated. On the other hand, since the film surface is printed with a certain name, design, etc. at regular intervals, if the printing interval (relative position) on both bonded films shifts, it will be printed at the specified position on the package. It becomes a defective product that does not come. Moreover, the relative positional relationship between the two films to be joined does not always match when the film transfer is stopped.

Therefore, prior to the joining process, if they do not coincide with each other, the idle roller 85 is moved and pulled out from the original film by a predetermined length so that the relative positions thereof coincide with each other. Then, after that, both films are clamped as shown below. In addition, in order to match the relative positions, a mark for alignment (reference) called an eye mark is printed on the side edge of the film. Cut at the position (the tip of the film is the eye mark). Then, it can be easily performed by adjusting the eye mark of the film being supplied so as to come to the film joining position (moving roller 83).

Further, in order to bond the films to each other as described above, the two films are sandwiched with the adhesive medium sandwiched therebetween. Therefore, the present embodiment is constructed as follows. That is, first, in this example, a pressure-sensitive adhesive tape is used as the adhesive medium. Therefore, the holder 89 is rotatably attached at a predetermined position on the upstream side of the moving roller 83 (the rotation axis is in the same direction as the film moving direction), and an adhesive tape (not shown) is wound around the holder 89 for use. Sometimes pull it out and position the tip of the adhesive tape to the opposite side edge. At this time, the adhesive surface is facing upward.

In this state, the film is pulled out from the preliminary raw film 12b, and the leading end of the film is placed on the adhesive surface of the adhesive tape (about half left). As a result, the adhesive tape is adhered to the tip of the film. In addition,
The adhesive tape is cut by an operator into a predetermined length before or after adhering the drawn film.

Then, the lower film 13 with the adhesive tape is stretched over the corresponding moving roller 83 as shown in FIG. 18A (the tip of the lower film 13 with the adhesive tape is moved to the moving roller 83). Place it so that it touches or is close to the sides). Further, at this time, since the lower film 13 pulled out from the original film 12a in use is stretched over the moving roller 83 on the opposite side, the moving rollers 83 are eventually connected and integrated. Since there are two films, the drive motor 93 is rotated to bring the two moving rollers 83 close to each other, and the lower films 13 are pinched from both sides. At the same time, since the exposed adhesive surface of the adhesive tape adheres to the lower film 13 in use, both lower films are adhered and integrated via the adhesive tape. Further, in this example, the joining process is performed on the packaging apparatus main body side when the film transfer is stopped, but the film is continuously pressed by the moving roller 83 for a certain period of time after the transfer is started. As a result, the adhesive tape passes between the rollers 83 in a pressurized state, so that the adhesive tape is more firmly joined and integrated over a wide range.

With this structure, the film and the adhesive tape can be continuously pressed by the both moving rollers for a certain period of time while the film is stopped. Therefore, even if the film is thick and difficult to adhere, the film and the adhesive tape are surely adhered. be able to.

Further, as shown in FIG. 18A, two lower films 13 drawn from the respective original films 12a and 12b between the two moving rollers 83 (adhesive tape on the tip of the lower film 13) Is attached), and the tip of the film on the spare side is in a free state, so the tip may fluctuate due to wind, etc., and the adhesive tape may stick to the lower film in use. . Therefore, in this example, as shown in FIGS. 15 and 18 (A), a rotation center is provided near the middle of both moving rollers 83,
A gate-shaped frame 106 arranged so as to straddle the lower film 13 is provided, and the top surface of the frame 106 is
A brush 107 extending in the longitudinal direction (film width direction) is provided, and a lever 108 is attached to the front side of the upper surface of the frame 106. Then, the lever 108 is tilted to the spare side (the switching work of the tilting direction of the lever 108 is manually performed), so that the brush 107 is brought into contact with the lower film 13 on the spare side and urged to the moving roller 83 side. This prevents the lower film from wobbling.

As described above, in this example, the film from the preliminary film 12b is connected to the film from the preliminary film 12b while a predetermined amount remains on the film 12a in use, so that both films are bonded and integrated. Figure 18 (B) in the state
Since the lower film 13 (in the left side in the drawing) which is in use also has a predetermined length as shown in FIG. 6, it is automatically cut at a predetermined position near the moving roller 83 by a cutter means (not shown). .

Further, the film supply 1 having the above-mentioned structure
1 has been described for the lower film 13,
Since the film supply 17 for the upper film 17 also has basically the same configuration (for example, the relative installation positions of the first and second fixed rollers and the idle roller may be different depending on the layout and the like), The description is omitted.

Further, in the above-mentioned embodiment, the film supply for both the upper film and the lower film has the structure with the idle roller which is the essential part of the present invention. Predetermined printing (design, advertisement, etc.) on both film surfaces at regular intervals (packaging manufacturing pitch)
This is because it is applied to the above. If there is no such printing, it is possible to use a structure that does not use the idle roller. That is, when there is printing on one film, in the present invention, at least the film supply on the printed film side may have a predetermined configuration.

Next, the operation based on the above-described configuration (a series of processes from the production of the product (sliced ham) to the packaging (production of a single package)) will be described. The slicer 1 sequentially cuts the raw wood 2 to produce sliced ham, and the sliced ham is delivered in a state where a predetermined number of laminated hams are stacked. Further, when the remaining amount of the raw wood being processed by the slicer 1 becomes low, the next raw wood 2 to be processed is supplied from the raw wood supply device 3 and placed on the raw wood 2 currently being cut. Thereby, sliced ham, which is an object to be packaged, is continuously manufactured.

The stacked sliced ham 5 produced and carried out by the slicer 1 is weighed when it is conveyed on the weighing machine 4, and then transferred to the sorting / sorting device 6, where the weight is used as a reference. Only those within the range are sorted into three rows, and are carried out in a state where they are lined up in three rows laterally with respect to the next-stage pool conveyor 7.

Then, from the pool conveyor 7 to the transfer device 8
After that, the three sliced hams 5 arranged side by side are transferred to the auxiliary transport device 25 and stopped at a predetermined position arranged in two rows in the front and rear by the stopper means. In this state, the automatic feeder 9
Thus, a total of six sliced hams 5 are gripped at once by the gripping portion 26 and supplied to a predetermined position of the packaging device main body 10 in the next stage, that is, in the pocket portion 13a of the lower film 13.

After that, by being successively conveyed over the packaging apparatus main body 10, a normal packaging process is performed, and the pocket 1
The sliced ham 5 stored in 3a has its upper opening covered with the upper film 16 and the inside of the pocket 13a is evacuated by the vacuum chamber 20. The 16 bonded portions are sequentially cut in the horizontal and vertical directions. As a result, a single (individual) package 95 is manufactured as shown in FIG.

When the film supply from the original film is cut off, the film to be used next is pulled out from the preliminary original film by the film supplies 11 and 17, and the adhesive tape is attached to the film currently in use at a predetermined timing. Are glued together. Therefore, the film that is currently in use is pulled out to the side of the packaging device body 10 as the packaging process proceeds, and the film that has been wound around the preliminary raw film is also pulled out. As a result, the lower and upper films can be continuously supplied without stopping the system, and a system with good operation efficiency is constructed.

Further, in the present embodiment, an apparatus for manufacturing a collective package in which a predetermined number of the packages (FIG. 19) manufactured as described above are stacked is arranged on the downstream side of the packaging apparatus main body 10. There is. That is, as shown in FIGS. 3 and 6, the finger conveyors 96 operating at a constant speed are arranged at the carry-out end of the packaging apparatus main body 10, and the three body packaging bodies 95 conveyed side by side are arranged at predetermined intervals. At that time (for the finger pitch), it is sequentially supplied to the next-stage integrated device 97.

The finger conveyor 96 is
A crossover conveyor 96a is provided on the carry-in side. The transfer conveyor 96a moves intermittently, and further, the leading end on the carry-in side moves up and down. Accordingly, when an empty bag containing no sliced ham is produced, the leading end of the transfer conveyor 96a on the carry-in side is lifted to disconnect the transport path, and the empty bag carried out from the packaging apparatus body 10 is moved downward. It is designed to be dropped and discarded. Further, as shown in FIG. 19, the package 9 carried out from the packaging device body 10
The three 5 are arranged side by side, and are arranged so as to be continuous (without a gap) in the front and rear, and moreover, the packaging device body 10
Since various processes that can be performed in the above are intermittently performed, the finger conveyor 96 is also driven intermittently. The moving speed is also higher than that of the packaging device body 10.

On the other hand, in the stacking device 97, as shown in FIGS. 20 to 24, four comb-shaped receiving plates 99 that move forward and backward by the cylinder 98 are provided at a position one step lower than the conveying surface of the finger conveyor 96. It is arranged. Further, in this example, three cylinders 98 are arranged corresponding to the transport paths for transporting the package 95, respectively, so that they can be independently expanded and contracted. More specifically, the cylinder 98
The connecting plate 101 is attached to the tip of the cylinder rod 98a, the bottom plate 102 is provided on the lower surface of the connecting plate 101, and the base end side of the upper and lower receiving plate 99 is attached to the upper end tip side of the bottom plate 102. Further, the slider 103 is attached to the connecting plate 101.
The slider 103 is slidably mounted on the guide rail 104 arranged in parallel with the cylinder rod 98a. As a result, due to the expansion and contraction of the cylinder 98, the receiving plate 99 attached to the tip side of the cylinder 98 also moves forward and backward, but at this time, the slider 103 and the guide rail 10 are moved.
4 allows stable linear reciprocating movement.

Furthermore, the stopper plate 100 is erected at a predetermined distance (at least a distance longer than the entire length of the package 95) from the carry-out end of the finger conveyor 96. When the cylinder rod 98a of the cylinder 98 is extended, the receiving plate 99 passes over the stopper plate 100 and its tip is located near the carry-out end of the finger conveyor 96 as shown in FIG. When 98a is contracted, the receiving plate 9
The tip of 9 is set to retract toward the cylinder 98 side with respect to the stopper plate 100.

As a result, in the state shown in FIG. 20, the package 95 carried out from the finger conveyor 96 drops and is placed on the receiving plate 99. Next, when the cylinder 98 is contracted at an appropriate timing, the package 95 placed on the receiving plate 99 moves following the receiving plate 98, but comes into contact with the stopper plate 100 to suppress the forward movement. Is
Eventually, since the support from below is lost, the belt is dropped onto the belt conveyor 105 arranged below it.

Further, on the conveying surface of the belt conveyor 105, step portions 109a to 109d are formed at appropriate positions, and predetermined portions of the package 95 are locked to the predetermined step portions 109a to 109d, so that the belt conveyor It is placed at a predetermined position on 105 in a predetermined posture. Then, in this example, by gradually shifting the contraction timing of the cylinder 98, the timing at which the packaging body 95 on the receiving plate 99 falls onto the belt conveyor 105 is changed, whereby
The three packages 95 are integrated.

Specifically, first, the finger conveyor 9
The package 95 conveyed on the 6 is transferred onto each receiving plate 99. Then, as shown in FIG. 22, when the substantially triangular first step portion 109a is located under the receiving plate 99 on the left side in the drawing, the corresponding cylinder is contracted to retract the receiving plate 99. As a result, the package 95 becomes the belt conveyor 105.
Side, and as shown, the pocket portion 95 of the package 95.
The top surface of a comes into contact with the surface of the first step portion 109a, and the side surface of the pocket 95a on the front side in the traveling direction is a small projection-shaped second portion arranged at a predetermined distance from the first step portion 109a. It contacts the stepped portion 109b. And the first step 1
Since 09a has a triangular shape, it has an inclined posture in which the rear side in the traveling direction rises as illustrated.

Then, the belt conveyor 105 moves forward,
As shown in FIG. 23, if the third step 109c comes to a predetermined position below the receiving plate 99 that constitutes the middle conveyance path,
The corresponding cylinder is contracted to retract the receiving plate 99.
As a result, the package 95 is dropped toward the belt conveyor 105, and the top surface of the pocket 95a of the package 95 comes into contact with the package dropped in the previous step as shown in the figure, and the front of the pocket 95 in the traveling direction is advanced. The side surface of the second step 109
It abuts on a third step portion 109c on a rectangular shape having a predetermined length, which is arranged at a predetermined distance from b. Then, since it is placed on the packaging body that has been previously arranged in the inclined posture, the packaging body dropped this time also has the inclined posture and is placed while being shifted by a predetermined distance in the traveling direction.

Further, the belt conveyor 105 moves forward,
As shown in FIG. 24, when the second to fourth step portions 109b to 109d reach a predetermined position below the receiving plate 99 which constitutes the right-side conveyance path in the drawing, the corresponding cylinder is contracted to retract the receiving plate 99. Let As a result, the package 95 is dropped toward the belt conveyor 105, and the top surface of the pocket 95a of the package 95 is dropped in the previous process as shown in the figure, and the third package
Of the small protrusion (higher than the second step 109b) in which the side surface of the pocket 95 on the front side in the traveling direction is located immediately in front of the third step 109b. It contacts the stepped portion 109d. Then, since it is placed on the packaging body that has been previously arranged in the inclined posture, the packaging body dropped this time also has the inclined posture and is placed while being shifted by a predetermined distance in the traveling direction. As a result, as shown in the drawing, the three packages 95 are stacked, and the stacking process is completed.

Then, while maintaining this state, the belt conveyer 105 moves forward with the movement of the belt conveyer 105, and when passing through the first labeling machine 110 disposed during the conveyance,
A strip-shaped seal 111 is attached to the back surface (the surface exposed to the upper side in the transporting posture (side surface opposite to the pocket portion 95a)) (see FIG. 25). As a result, the three packages 95 are integrated. In addition, a barcode, a content display, and the like are printed on the surface of the sticker.

Then, the above three integrated package 9
5 is transferred to the belt conveyor 113 of the next stage after the traveling direction is changed 90 degrees through the turn conveyor 112,
Be transported. Then, by the second label sticking machine 114 arranged in the middle of the transportation, three packaging bodies are provided on the side opposite to the sticking surface of the seal 111, that is, on the lower side in the transportation posture in which the pocket portion 95a is formed. A belt-shaped seal 115 is attached so as to span 95 (see FIG. 26). These three seals 111 and 115 fix the three packages 95 from both sides thereof. As a result, the collective package 116 is completed.

In this example, a turn conveyor 117 is further arranged at the carry-out end of the belt conveyor 113, the course of the manufactured collective package 116 is further polarized by 90 degrees, and then transferred to the weighing machine 118, Measure the weight while transporting. Then, it is determined whether or not the weight of the entire assembly 116 is within a predetermined reference range, and the determination result is output to the next-stage sorting device 119 (actually, a detection signal is sent when a weight error occurs). .

The sorting device 119 is provided with arms on both sides of the conveying path, and serves as a guide for the conveying path as shown in the figure in a steady state to ensure smooth conveyance of the collective package 116. When there is a weight abnormality, the arm rotates in the same direction with the upstream side as the center of rotation to block the path of the collective package 116 and discharge it sideways.

Further, on the downstream side of the sorting apparatus 119, a conveyor 120 whose course is different by 90 degrees is arranged, and the collective packages 116 that have passed through the sorting apparatus 119 are sequentially transferred onto the conveyor 120. Stopper means (not shown) is arranged at a predetermined position on the downstream side of the conveyor 120, and the leading collective package 116 is locked by the stopper means and its forward movement is suppressed. The collective package 116 that is sequentially conveyed thereafter contacts the immediately preceding collective package, and the forward movement is suppressed. As a result, as shown in FIG. 6, the front and rear of the collective package 116 that has been conveyed at a constant interval are in contact with each other.

A boxing robot 121 is arranged on the downstream side of the conveyor 120, and a predetermined number (three in this example) of the collective packages 11 locked by stopper means.
6 are sequentially filled into the box (case) and supplied. In this example, as the boxing robot 121, for example, Top Open Caser TDC-50 (manufactured by Omori Machinery Co., Ltd.) is used. This TDC-50 is
Although not shown in detail, the carton is stuck to the body (folded in a state where the top and bottom are not adhered) 12
1a is drawn out one by one in order and opened, and the part which becomes the bottom is bent to form a box body 121b in an open state. Then, using the suction type supply robot 121c,
One collective package 116 is sucked and held at the same time, and a box 121
Supply in b. Then, by performing a predetermined number (six times in this example) of such supply processing, the collective package 116 becomes the box body 1.
21b are supplied in a three-row, six-stage stacked manner (see FIG. 27A).

When a predetermined number is packed and supplied, the lid part forming the box is folded to close the opening, and then the tape is sent to the next tape sealer 123. And
With the tape sealer 123, as shown in FIG.
A tape 125 is attached to the joint portion of the bottom portion 124a forming the box body 124 and the lid portion 124 to close the box body 124. This completes the boxing process.

Although sliced ham was used as the items to be packaged in the above-mentioned embodiments, the present invention is not limited to this, and various types of items can be used, and a manufacturing apparatus can also be used when the items to be packaged are changed. It goes without saying that an appropriate device can be used instead of the slicer described above. Further, in the deep-drawing type packaging apparatus main body, vacuum packaging was performed, but the present invention is not limited to this, and an inert gas replacement treatment or no treatment is performed (air exists in the pocket portion). Etc. can be used. further,
