Description

  The present invention belongs to the technical field of an automatic packaging machine that automatically fills and wraps a material to be packaged (contents) using a packaging film (packaging material). The present invention relates to a cooling mechanism of an R cutter device in a vertical multi-row automatic packaging machine that forms a stick packaging bag by forming into a cylindrical shape.

  2. Description of the Related Art Conventionally, there is a vertical multi-row automatic packaging machine configured so that a plurality of stick-type packaging bags can be continuously sealed at a time. Each of the packaging films cut into a plurality of pieces is wound around each former pipe configured in a multi-row form, formed into a cylindrical shape, and then longitudinally sealed against the seam of the packaging film by a longitudinal heat sealer. To form a cylindrical shape, and then a horizontal seal is applied to a specified position of the cylindrical packaging film by a horizontal heat sealer.

  The vertical multi-row automatic packaging machine uses a filling pipe to fill the packaging material (contents) into the resulting bag-shaped packaging film, and then horizontally seals and seals the packaging material inlet. Then, the vicinity of the center of the sealed horizontal seal portion is cut off using a cutter device, and finally the stick-shaped packaging bags in the individual packaging form are multi-row and continuously sealed. It has become. An example of such a vertical multi-row automatic packaging machine is disclosed in Patent Document 1.

  In the conventional individual packaging bags as described above, when a large number of finished packaging bags are collected, the corners of the cut portions and the bag portions of other individual packaging bags come into contact with each other, and a hole is formed in the packaging bag portion. Accidents may occur. For this reason, it is processed into a shape (so-called “R-cut” shape) in which the corner of the cut portion of the horizontal seal is cut off to prevent such an accident.

  In the cutter device that cuts into the R-cut shape, unlike the case of the straight cut, a punching structure is required to cut off the corner portion. Prior to this punching operation, it is necessary to sufficiently cool the punched portion (near the center of the lateral seal portion) of the R-cut packaging bag. This is because if the packaging bag in the warmed state immediately after heat sealing is punched out as it is, the polyethylene in the welded packaging film is in a soft state, so it cannot be punched cleanly as it is, and fine cutting residue will occur. This is because the sharpness deteriorates and the finish deteriorates.

  FIG. 10 is a side view of a cooling device of a conventional R cutter device as viewed from the side. As shown in FIG. 10, the R cutter apparatus installed in the vertical multi-row automatic filling and packaging machine has one cutter portion 120 prepared for the number of rows and attached to the cutter frame 124, and is parallel to the horizontal direction. is set up.

  In addition, the cutter frame 124 to which the cutter units 120 are attached by the number of rows is provided with holes for collecting chips (R-cut scraps) punched by the cutting blade 122 and the punching die 123. The scrap removing pipe 162 is fitted into the hole and extends to the vicinity of the punching die 123. The plurality of scrap collecting pipes 162 are connected to a dust collecting pipe 161 installed on the back surface of the cutter frame 124 to constitute a dust collecting mechanism 160.

  Further, in the punching type cutter device, since the separated packaging bag after the punching operation may adhere to the punching die 123 and does not fall, a peeling mechanism 170 for peeling the bag from the punching die is installed. Yes. As shown in FIG. 10, the peeling mechanism 170 includes a peeling lever 173 provided immediately below the punching die, an air cylinder 171 attached to the packaging machine body, and a drive shaft 172 of the air cylinder 171. After the punching operation, air is supplied from the packaging machine, the drive shaft 172 of the air cylinder 171 moves forward, and the peeling lever 173 screwed to the drive shaft 172 causes the packaging bag to be peeled off from the die. ing.

And the conventional cooling device 180 is made to inject the air for cooling with respect to the packaging bag which carries out R cut from diagonally upward of an R cutter apparatus, and specifically, as shown in FIG. An injection unit 181 is installed on the back surface.

In addition, although the number of rows of the vertical multi-row automatic packaging machine in FIG. 1 is described as an example of 6 rows, an arbitrary value corresponding to the width of the raw roll film can be adopted as the number of rows.

  As shown in FIGS. 1 and 2, 1F is a main body frame, 2 is a hopper containing a material to be packaged (contents), 3 is a material to be packaged supplied from the hopper 2 and is supplied to a filling pipe 4 The metering board 4 is formed into a plurality of wrapping films F ′ that are slit and narrowed into a substantially cylindrical shape, and is a filling pipe that serves as an input passage for the material to be packaged, 5 is a vertical sealing device, and 6 is below it. A lateral seal device provided in the bag, 7 is a bag guide for supporting the completed continuous packaging bag, and 8 is an R cutter device that is punched into an R-cut shape near the center of the lateral seal of the continuous packaging bag to form an individual packaging bag having no corners. , 9 is a slide for receiving the separated individual packaging bags, and 10 is an operation panel box.

  In FIG. 2, FH is an original roll wound with a wide packaging film (wrapping material), F is a wide film drawn from the original roll FH, FX is the wide film F and the above-mentioned filling pipe 4 is a slitter device that slits into a plurality of narrow packaging films F ′ according to the number of rows of four. The packaging films F ′ sequentially drawn downward in accordance with the vertical movement of the horizontal sealing device 6 are formed into a substantially cylindrical shape so as to wrap around the respective filling pipes 4.

Seal molding is performed in a row.

  The above operation is continuously repeated, and the central portion of each horizontal seal is cut up and down by the R cutter device 8 so that a large number of stick type individual packaging bags can be continuously produced at a time. It is configured. As in FIG. 1, 2 is a hopper, 3 is a metering board, and 11 is a motor that drives the metering board 3.

  FIG. 3 is a side view of the R cutter device 8 in the vertical multi-row automatic packaging machine of the present invention, and FIGS. 4 and 5 are top views of the R cutter device 8 similarly. 4 shows a state before the cutter blade and the punching die are mated, and FIG. 5 shows a state when the cutter blade and the die are mated. As shown in FIGS. 3 to 5, in the R cutter device 8, one cutter portion 20 is prepared for the number of rows and attached to the cutter frame 24, and is arranged in parallel in the horizontal direction. Note that the number of columns in FIGS. 4 and 5 is described as an example of seven columns.

  A cutting blade 22 is incorporated in the cutter unit 20 and is connected to an air cylinder 21 that drives the cutting blade 22 by a drive shaft. An R-cut punching die 23 is provided at a position facing the cutting edge of the cutting blade 22 with a certain interval, and a continuous stick-shaped packaging bag FZ that is not separated between the cutting edge of the cutting blade and the cutting die 23 is provided. It is set.

  Next, in the cooling mechanism of the present invention, as shown in FIG. 3, the back surface injection unit 30 that jets cooling air to the back surface of the continuous stick-shaped packaging bag FZ that is not cut is attached to the cutter frame 24. In addition, a back surface injection port 32 is perforated in the cutter frame 24 so as to be connected thereto. Moreover, the front injection part 31 which injects the air for cooling with respect to the stick-shaped packaging bag FZ front is attached to the cutter part 20, and the front injection port 33 is pierced in the cutter part 20 so that it may connect with this. Yes.

  Then, the cooling action for the punched portion of the packaging bag is preferably performed in the R cutter device in which the punched portion to be cooled is stopped. Since the front air injection port is perforated, the cooling air can be directly ejected to the stopped punched portion, and an efficient cooling mechanism can be configured.

The cooling mechanism operates as follows.
(1) The packaging bag FZ to be cooled is moved downward intermittently, and stops at a position as shown in FIG. 3 immediately before the R-cut. When this position is reached, the vertical multi-row automatic packaging machine supplies cooling air to the back surface injection unit 30 and the front surface injection unit 31, and air is ejected from both the back surface injection port 32 and the front surface injection port 33. The cut punched portion FY is cooled.

(2) After the cooling is completed, the cutter unit 20 is driven, and R-cut is applied to the continuous stick-shaped packaging bag FZ that is not cut off.

(3) After the R-cut is performed, the vertical multi-row automatic packaging machine supplies air to the back surface injection unit 30 and stops supplying air to the front surface injection unit 31. As a result of such air supply, the packaging bag after the R cut is peeled off from the punching die 23 of the cutter unit 20 by the air ejection from the back surface injection port 32.

  That is, in the air supply control by the vertical multi-row automatic packaging machine, air is blown out from the back surface injection port 32 and the front surface injection port 33 only during the cooling time, and the R cut time is output from the back surface injection port 32 and the front surface injection port 33. Air ejection is stopped, and air is ejected only from the back surface injection port 32 during the period after the R cut.

  Such an air supply control method is a method in which air is ejected only when necessary and the air ejection is stopped as much as possible at other times (packaging bag transfer period, etc.). This is employed when it is desired to suppress the air consumption or when the temperature rise of the packaging bag itself is small.

In addition, as an air supply control method by the vertical multi-row automatic packaging machine other than the above, it is also possible to do the following.
(1) Air ejection from the back surface injection port 32 stops only during the R-cut period, and air ejection is always performed during other periods.
(2) Air ejection from the front injection port 33 stops both at the R-cut time and the time after the R-cut, and performs air ejection at other times.

  By doing so, the air ejection time becomes relatively long, and such an air supply control method is adopted when it is desired to cool the entire packaging bag as long as possible.

  As described above, the present invention described with reference to FIGS. 3 to 5 has a cooling mechanism that efficiently cools the R-cut punched portion by controlling the air supply and also has a function of peeling off the packaging bag after the R-cut punching. Can be provided.

  Next, the cooling mechanism of the present invention is configured as follows, as shown in FIGS.

(1) The cutting blade 222 of the cutter unit 220 is provided with air ejection holes 42, 43, and 44 for discharging cooling air. In the present embodiment, an example in which three holes are perforated has been described. However, the number of the air ejection holes is an arbitrary number depending on design matters such as the strength of the cutting blade 222 and the amount of cooling air ejection. Can be adopted.

(2) The connecting member 41 that attaches the cutting blade 222 to the drive air cylinder 221 is provided with an opening groove 45 in the center portion that contacts the air ejection holes 42, 43, 44.

(3) The air supply part 40 is provided in the main body part 47 of the cutter part 220 to which the drive air cylinder 221 is attached and the cutting blade 222 is accommodated. It is connected to the cavity 46.

(4) As a result of the configuration described above, the cooling air connected to the cutter unit 220 passes through the air supply unit 40, the hollow portion 46 of the main body portion 47, and the opening groove 45 of the connecting member 41. The cutting blade 222 and the packaging bag FZ are directly cooled by being ejected from the air ejection holes 42, 43, 44, and an efficient cooling mechanism can be configured.

  The cooling mechanism operates as follows, as shown in FIGS. 6 to 9.

(1) The packaging bag FZ is intermittently moved downward, and stops at a position as shown in FIG. 6 immediately before R-cutting. When this position is reached, the cutter unit 220 is driven, and an R-cut is applied to the continuous stick-shaped packaging bag FZ that is not cut off.

(2) At the same time as the R-cut is performed, the vertical multi-row automatic packaging machine sends air from the air supply unit 40, and cuts through the hollow portion 46 of the main body portion 47 and the opening groove 45 of the connecting member 41. Air is jetted from the air ejection holes 42, 43, and 44 of the 222 to cool the cutting blade 222 directly, and the punched chips (R-cut residue) are sent to the dust collecting passage 225 with force. .

  Such an air supply control method is a method in which air is blown out only at the time of R-cut and is stopped as much as possible at other times. This is employed when it is desired to suppress the air consumption or when the temperature rise of the packaging bag itself is small.

  As an air supply control method by a vertical multi-row automatic packaging machine other than the above, it is also possible to do the following.

(1) The packaging bag FZ to be cooled is moved downward intermittently, and stops at a position as shown in FIG. 6 immediately before the R-cut.

Air injection is performed from 42, 43, and 44 to cool the R-cut punched portion FY.

(2) After the cooling is completed, the cutter unit 220 is driven, and R-cut is applied to the continuous stick-shaped packaging bag FZ that is not cut off.

(3) Simultaneously with the R-cut, the vertical multi-row automatic packaging machine sends air again from the air supply unit 40 and cuts through the hollow portion 46 of the main body portion 47 and the opening groove 45 of the connecting member 41. Air is jetted from the air ejection holes 42, 43, 44 of the blade 222 to cool the cut blade 222 directly, and the punched chips (R-cut residue) are fed into the dust collecting passage 225 with force while peeling off. Yes.

  By doing in this way, the air blowing time becomes relatively long, and such an air supply control method is adopted when it is desired to cool the completed packaging bag.

  As described above, the present invention described with reference to FIGS. 6 to 9 efficiently cools the R-cut punched portion by controlling the air supply, and at the same time pulls off the chips (R-cut residue) generated during the R-cut punching. A cooling mechanism that can be well fed into the dust collection passage 225 can be provided.
