Description

  The present invention relates to a suction cutter. More specifically, the present invention relates to a suction cutter that can easily and safely open a packaging film that is in close contact with the outer periphery of a product so as not to damage the contents of the product.

  Data media such as CDs and game software are sold by being wrapped in close contact with a film after being housed in a synthetic resin case. This film is intended to assure the purchaser that a third party has not touched the product, but is difficult to open because it is in close contact with the case. Also, if you try to make a cut with a cutter knife, the lower case of the film will be damaged. In addition, the tip of the cutter knife may slip and cut your finger. In addition, foods such as lunch boxes and prepared dishes are sold by wrapping them in a film such as polystyrene foam and are difficult to open.

  As an apparatus for automatically cutting an adhesive tape that closes a packaging box, for example, in Patent Document 1, a cardboard case carried by a belt conveyor is positioned with a stopper, and the upper and lower cutters are expanded and contracted to cut the adhesive tape. Next, a vacuum cup that opens and closes with an air cylinder is disclosed. On the other hand, Patent Document 2 discloses a technique in which a small scratch is applied to a shrink film in advance and an adhesive tape piece is attached on the wound so that the shrink packaging of cup noodles can be easily opened. Further, in Patent Document 2, when a film is scratched, the lower end of the cylindrical body is pressed onto the film, the inside of the cylindrical body is decompressed, the film is sucked, and a blade edge having a predetermined shape such as a U shape is obtained. It is disclosed that a part of the shrink film is torn with a cutter equipped with the above.

JP 11-91746 A JP 2004-10078 A

  The cardboard case opening device of Patent Literature 1 and the device for scratching the shrink film of Patent Literature 2 can each efficiently process a large amount of products, but it is easy when consumers open the packaging of products. It is not usable. An object of the present invention is to provide a safe and simple suction cutter that allows a consumer to easily open a packaging film or the like. Furthermore, the present invention is a surgical suction cutter capable of cutting only the skin without damaging the internal tissue during surgery, and food processing capable of cutting only the epidermis without damaging fish eggs or internal meat. An object of the present invention is to provide a suction cutter.

  In order to solve such a problem, the suction cutter of the present invention includes an adsorption member, means for raising and lowering or tilting the adsorption member, and means for forming a cut in the film that is adsorbed and lifted by the adsorption member. (Claim 1). “Means for forming a cut” include a cutting blade, a needle, a nichrome wire, a laser knife, and the like. As such a suction cutter, it is preferable to have a pressing portion that presses an adjacent portion when the film is lifted (Claim 2). In that case, it is preferable that the means for forming the cut is provided in the pressing portion.

  Further, the suction member is preferably attached to the tip of the support rod, and as a means for moving the suction member up and down, a suction cutter in which a grip portion is attached to the base end of the support rod is preferable. In addition, the suction member is attached to the lower end of the support bar, and as a means for raising and lowering the suction member, a knob is provided at the upper end of the support bar, and a press member is provided between the knob piece and the press member. A spring that urges the valve downward may be interposed (claim 5). The adsorbing member may adsorb the film by a negative pressure (Claim 6), or may adsorb the film by an adhesive (Claim 7). As means for generating the negative pressure, there are a vacuum cup, a compressor, a vacuum pump, and the like.

  In the suction cutter of the present invention, the suction member is brought into contact with a film such as a film for packaging a product and is sucked, and then the suction member is moved up and down or tilted by means for lifting or tilting the suction member. At that time, since the film is somewhat separated from the package such as the product, the cut can be made by means of forming a cut without damaging the product. Then, by removing the suction cutter and putting a finger or the like into the cut and tearing it, the film can be easily broken largely and the package can be opened. Furthermore, since the means for forming the cut is adjacent to the adsorption member, the user is less likely to injure his finger.

  When the film is lifted, the suction cutter provided with a pressing portion that presses an adjacent part can be lifted while pressing the film, so that the film can be tensioned and easily cut. When the means for forming the cut is provided in the pressing portion, the film can be cut by touching the means for forming the cut by an operation of lifting the film. Therefore, a cut can be formed more reliably.

  In the suction cutter in which the suction member is attached to the lower end of the support bar and the knob is provided on the upper end of the support bar as means for raising and lowering the suction member, the suction member can be operated by holding the knob. Therefore, it is possible to accurately move the film up and down and tilt. In addition, the suction member is attached to the lower end of the support bar, and as a means for raising and lowering the suction member, a knob is provided at the upper end of the support bar, and a press member is provided between the knob piece and the press member. If there is a spring that urges downward, hold the knob and press the suction cup against the product, etc., because the pressing part will press the film with the urging force of the spring. There is no need to hold down, and operation is easy.

  When the adsorbing member adsorbs the film by negative pressure, it is easy to remove the film from the adsorbing member after opening. In the case where the adsorbing member adsorbs the film with an adhesive, even an air-permeable film such as a porous film can be adsorbed.

  Next, an embodiment of the suction cutter of the present invention will be described with reference to the drawings. The suction cutter 10 of FIG. 1 has a bottomed cylindrical case 11, a pressing member 12 slidably accommodated in the case, and an upper end fixed to the center of the top surface of the case 11. A support bar 13 that penetrates and extends downward, a suction cup 14 attached to the lower end of the support bar, a spring 15 interposed between the top surface of the case 11 and the pressing member 12, and an inner periphery of the pressing member 12 are provided. And the cutting edge 16 to be formed. In this embodiment, the cutting blade 16 is “means for forming a cut”.

  The case 11 is made of, for example, a synthetic resin, and may be a cylinder or a square tube. In this embodiment, the case 11 also serves as a knob. A boss 17 for fixing the upper end of the support bar 13 is projected from the inner bottom surface of the case 11, and the upper end of the spring 15 is supported and fixed by the boss 17. At the lower end of the case 11, for example, a pair of inward claws 18 that restrict the protruding end of the pressing member 12 are provided. The nail | claw 18 is provided in the elastic tongue piece cut | disconnected from the other part by the slit, and it can be expanded elastically now.

  The pressing member 12 has a bottomed cylindrical shape, and includes a boss 19 that guides the support bar 13 on the inner surface and supports the lower end of the spring 15 on the outer surface at the center of the top surface. The lower end of the pressing member 12 is a portion that comes into contact with the film 20 and is flat so that it can come into contact with the surface of the product 21 or the like. A step portion 22 that engages with the claw 18 of the case 11 is formed on the outer surface near the lower end of the pressing member 12. The case 11 and the pressing member 12 can be assembled together by engaging the claw 18 with the step portion 22. In the assembled state, the lower part of the pressing member 12 protrudes somewhat from the lower end of the case 11.

  A cutting edge 16 is fixed to the inner periphery near the lower end of the pressing member 12. The cutting edge 16 is made of a thin annular plate or the like, and is usually made of metal. However, even a hard synthetic resin can be produced. The edge (tip) 16 a of the cutting edge 16 is recessed inside the lower end of the pressing member 12. Since the edge 16a of the cutting blade 16 is retracted from the lower end of the pressing member 12 in this way, the user is safe with a low risk of injury of a finger or the like. Further, the product under the coating 20 is not damaged. In addition to a plate-shaped cutting blade, a needle-like or triangular-shaped sharp projection can also be adopted. “Means for forming cuts” in the present application include not only such cutting blades and protrusions, but also means for directly breaking a film such as a needle or a cone, heat generation means such as nichrome wire, and a laser knife used for surgery. .

The suction cup 14 is a so-called vacuum cup formed from rubber or the like in a cup shape. That is, when the peripheral lip part is pressed against the film 20 to be deformed flatly and then the pressing force is loosened, the inside of the lip part is decompressed and the film 20 can be adsorbed. In this embodiment, the number of suction cups 14 is one, and the number of support bars 13 is also one. However, as will be described later, two or more suction cups may be employed. When the film 20 is porous or fibrous, an adhesive member coated with an adhesive can be adopted as the adsorption member in place of the suction cup that is difficult to adsorb due to air leakage. Moreover, an adhesive can be applied to the lower surface of the sucker, or the sucker material itself can be formed of an adhesive material such as a silicone resin (silicone rubber). In that case, the adsorbing force becomes strong, and there is an advantage that the adsorbing can be performed even if some air leakage occurs.

  The spring 15 is a compression coil spring, is disposed around the support rod 13, is interposed between the case 11 and the pressing member 12, and urges to widen the distance between the two. Two or more springs 15 may be provided. Also, other forms of springs such as leaf springs can be employed.

  In order to break the film 20 of the product 21 using the suction cutter 10 configured as described above, first, the outer side of the case 11 is picked as shown in the first process (contact process) S1 of FIG. The pressing member 12 is pressed against the surface of the product 21. As a result, the suction cup 14 descends and comes into contact with the coating 20 while the spring 15 is contracted as in the second step (pressing / sucking step) S2. At this time, the suction cup 14 is elastically deformed to adsorb the film 20.

  Next, when the suction cutter 10 is separated from the product 21, the case 11 and the suction cup 14 are raised while pressing the pressing member 12 against the product side by the urging force of the spring 15 (cutting process). Therefore, the central portion of the film 20 can be pulled up by the suction cup 14 while pressing the film 20 with the annular bottom surface of the pressing member 12. Thereby, there is a gap 23 between the film 20 and the product 21, and that portion hits the edge 16 a of the cutting edge 16, and the film 20 can be cut out in a substantially circular shape. Even if it is not cut cleanly, if a part can be cut out in an arc shape, the film 20 can be broken by putting a finger or the like into the part. As described above, according to the suction cutter 10, the film 20 such as a packaging film for the product 21 can be opened easily, safely, and without damaging the product.

  In the suction cutter 10 of FIG. 1, the case 11 has a bottomed cylindrical shape, and a pressing member 12 and a spring 15 are accommodated therein. For this reason, mechanical features do not appear outside, and it is easy for the user to be familiar and easy to handle. However, like the suction cutter 25 shown in FIG. 2, a plate-like or bar-like knob 26 can be provided on the upper end of the support bar 13 instead of the case. In that case, the suction cup 14 provided at the lower end of the support bar 13 can be screwed to the support bar and used to prevent the pressing member 12 from coming off. A stopper made of a retaining ring or the like may be provided below the support bar 13. As the retaining ring, a C-type retaining ring or an E-type retaining ring can be used.

  Further, in this suction cutter 25, the pressing member 12 is not a cylindrical shape, but is a component composed of about 3 to 6 L-shaped legs 27 and bosses 19. Further, instead of the disc-shaped cutting blade, a cutting blade 28 is formed integrally with each leg 27. Since this mechanism appears outside, it can also be used as a design.

  The suction cutter 30 shown in FIG. 3 a uses the reciprocating motion generated between the case 11 and the pressing member 12 for suction of the film. This is provided with sealing materials 31 and 32 such as O-rings on the outer periphery and inner periphery of the pressing member 12, respectively, so that the space between the pressing member 12 and the case 11 and between the pressing member 12 and the support rod 13 are airtight. Then, a pipe having a passage 33 at the center is adopted as the support bar 13, and the passage 33 and the inside of the suction cup 14 and the passage 33 and the case 11 are communicated with each other. Further, the case 11 is provided with a check valve 34 through which air passes only from the inside to the outside.

  In this embodiment, the edge 16a of the cutting edge 16 is bent somewhat downward to make it easier to hit the film. Further, as shown in FIG. 3 b, a sawtooth edge 16 a is employed as the cutting edge 16.

The suction cutter 30 configured in this way can be used in the same manner as the suction cutter 10 shown in FIG. 1, but when the case 11 is released, the negative pressure generated in the case can be used for suction of the suction cup 14, The adsorptive power becomes stronger and the film can be pulled up firmly. Even if the film is slippery, the saw-toothed edge 16a is easily caught on the film, so that the film can be more reliably broken.

  The suction cutter 35 shown in FIG. 4 is provided with a cutting blade holding member 36 inside the pressing member 12 so as to be rotatable and not move in the axial direction. The cutting blade holding member 36 has a bottomed cylindrical shape, and includes a boss 37 through which the support bar 13 penetrates in the center. Further, a spiral protrusion 38 is provided on the outer surface of the support bar 16, and a spiral concave groove 39 that is screwed with the protrusion 38 is provided on the inner surface of the boss 37 of the cutting blade holding member 36. The lead angle of the helix is gentler than that of a screw, and is such that axial force can be converted into rotational torque. Moreover, it is preferable to set it as two or more articles | stripes. However, it may be one. Further, in this suction cutter 35, a bellows 40 is provided between the top surface of the case 11 and the pressing member 12, and a passage 33 is provided in the support rod 16.

  In the suction cutter 35, when the case 11 is pressed, and when the force for pressing the case 11 is loosened and separated from the product, the cutting blade holding member 36 is rotated by the screwing of the spiral protrusion 38 and the groove 39. Therefore, the adsorbed film is cut while being rotated by the cutting blade 28, and can be cut more reliably. Further, when the case 11 and the pressing member 12 are separated from each other, the bellows 40 is stretched and sucks air. Therefore, the suction force by the suction cup 14 can be improved while reducing the number of seal portions as compared with the cylinder type as shown in FIG. 3a.

  In the suction cutter 42 shown in FIGS. 5 and 6, the case 11 and the pressing member 12 each have a rectangular tube shape. Further, the planar shape of the square tube is substantially rectangular, and two support bars 13 and two suction cups 14 are provided. An intermediate wall 43 that supports the cutting blade is provided at the center of the pressing member 12 so as to partition the two suction cups 14. In this embodiment, a heater 44 such as a nichrome wire is disposed along the lower surface of the wall 43 as a cutting blade, and the battery B is placed on the upper surface of the pressing member 12.

  The suction cutter 42 can be burned off by the heat of the heater 44 instead of cutting the film. Therefore, depending on the type of film, it can be more easily cut, perforated, and opened. Instead of the heater 44, a plate-shaped cutting blade may be provided, and a plate-shaped or conical cutting blade may be provided together with the heater 44. Moreover, when providing a hook-shaped cutting blade (refer FIG. 7), after the front-end | tip of a hook breaks a membrane | film | coat, a membrane | film | coat can also be cut as it is.

  The suction cutter 45 shown in FIG. 7 is provided with a frame-shaped guide groove 46 extending in the front-rear direction at the upper part of the pressing member 12, and a slide part 48 provided at the upper part of the cutting blade holding member 47 is slidable in the front-rear direction. ing. The pressing member 12 includes, for example, two legs 27. In FIG. 7, the front leg is omitted, and only the other leg is shown. A cutting blade 16 is provided at the lower end of the cutting blade holding member 47. As the cutting edge 16, a hook-shaped one having a sharp tip 16 b and an edge 16 a that is recessed following the tip is employed.

The slide portion 48 of the cutting blade holding member 47 is provided with a cam groove 49 that is inclined forward and downward, and a pin (cam follower) 50 that engages with the cam groove 49 protrudes from the support rod 13 that supports the suction cup 14. Has been. The support bar 13 is held up and down by a pressing member 12 within a predetermined stroke range, and is urged upward by a spring 15 against the pressing member 12. A knob 26 is provided at the upper end of the support bar 13. Instead of the cam mechanism 2 by the cam groove 49 and the pin 50, the cutting blade holding member 47 is moved back and forth as the support bar 13 moves up and down, such as a cam mechanism in which the inclined surfaces are slidably contacted. This kind of mechanism can also be adopted. Further, it is possible to employ a mechanism that swings the cutting blade holding member 47 as the support bar 13 moves up and down.

  In the suction cutter 45 of FIG. 7, the support bar 13 is raised in a normal state, and the pin 50 is engaged with the upper side in the cam groove 49. The slide portion 48 of the cutting blade holding member 47 moves to the front side in the guide groove 46, and the cutting blade 16 protrudes forward from the suction cup 14. In order to use the suction cutter 45, first, the pressing member 12 is picked and the legs 27 are placed on the product or the like (first step S1). Next, the knob 26 is pressed downward against the urging force of the spring 15. At this time, if the gripping piece 26 is pressed down with the other hand while pressing the pressing member 12 with one hand, the pressing member 12 is stabilized and the operation can be performed safely. When the support bar 13 is pushed down, the slide part 48 moves backward based on the engagement between the pin 50 and the cam groove 49 as the suction cup 14 is lowered (second step S2). The suction cup 14 is lowered to the same level as the lower end of the pressing member 12 or lower than the lower end to adsorb the film.

  Next, when the force to push the knob 26 is loosened, the support bar 13 is raised by the biasing force of the spring 15, and the suction cup 14 is raised while pulling the film 20 away from the product etc. The slide part 48 moves forward (third step S3). Thereby, the tip 16b of the cutting blade 16 perforates the pulled up film 20, and then the film 20 is torn from the part where the edge 16a is perforated. The user can also make a large cut in the coating 20 by sliding the pressing member 12 along the surface of the product. In addition, if the front-end | tip 16 of the cutting blade 16 enters the inside of the one end membrane | film | coat 20, adsorption | suction may lose | release after that. This is the same for any of the suction cutters described above.

  The suction cutter 52 shown in FIG. 8 is characterized in that a conical cutting blade 53 is arranged at the center of the suction cup 14. A pipe-like support rod 13 is slidably and airtightly provided around a rod-like cutting blade holding member 36 that holds the cutting blade 53. Other points are the same as those of the suction cutter 42 of FIGS. In the suction cutter 52, the upper end of the cutting blade holding member 36 is attached to the pressing member 12, and the support bar 13 that supports the suction cup 14 is attached to a case (not shown) that also serves as a knob. In the suction cutter 52, most of the cutting edge 53 is hidden inside the suction cup 14 in a normal state, and when the support bar 13 is pushed down, the suction cup 14 is lowered below the cutting edge 53 and sucks the film. To do. When the suction cup 14 is raised, the coating is cut by the cutting blade 53.

  In the suction cutter 54 shown in FIG. 9, the support bar 13 that supports the suction cup 14 does not move up and down, but the left and right can be rotated synchronously around the vicinity of the upper end. In the natural state, this is inclined toward the center as in the third step S3. When the case is lowered, the left and right suction cups 14 face straight down to adsorb the film 20 (second step S2). When the case is separated from the product, the left and right suction cups 14 remove the film. It rotates so that it may approach to a center (3rd process S3). Therefore, the cutting blade 16 hits the lifted film 20 and can be cut.

  On the other hand, in a natural state, as in the second step S, the left and right support rods 15 can be directed straight down. In that case, the suction cup 14 is inclined inward by the operation so that the film is cut. This will turn straight down again after the operation is complete.

In any of the above embodiments, the adsorption of the film by the suction cup is based on the premise that a product or the like under the film supports the film so that the film is not deformed. However, if the product on the lower side is flexible and it is difficult to support the coating, the air inside the cup-shaped pressing member 12 is sucked by a pump 57 such as the suction cutter 56 shown in FIG. It is preferable to employ a pressure. The pump 57 includes a check valve 58 that allows a one-way flow of air from the presser member 12 into the pump 57, a rubber ball having an ellipsoidal shape, and an air flow from the inside of the pump 57 to the outside. It is a manually operated pump provided with a check valve 59 that allows flow in the direction. It is also possible to use a motor-driven vacuum pump or compressor, or a venturi-type negative pressure generator that obtains a negative pressure with a jet of high-pressure air. Examples of the compressor include those that exhibit a suction action used by dentists.

  The suction cutter 56 draws the coating film 20 with a negative pressure inside the pressing member 12 without using a suction cup, and cuts it with the cutting blade 16. Therefore, it is not necessary to strongly press the product below the film 20. Moreover, there are few movable parts and sliding parts, and the structure is simple. As indicated by an imaginary line 16 a, the cutting blade holding member 36 that holds the cutting blade 16 may be protruded upward from the top surface of the pressing member 12 so that it can be moved up and down independently of the pressing member 12. . Further, a rubber lip 60 may be provided on the outer periphery of the lower end of the pressing member 12 to improve the sealing property with the film and to reduce air leakage. Further, as shown in FIG. 3 or FIG. 4, after using the suction cup 14, the air in the suction cup may be sucked by a pump via the passage of the support bar 13 to make the suction cup 14 have a negative pressure. Also in this case, the coating film 20 is drawn by the negative pressure in the suction cup 14 and cut by the cutting blade 16. Therefore, it is not necessary to press the suction cup 14 strongly.

  The cutting blade 62 shown in FIG. 11 is formed by rounding saw blades made of a thin metal plate into a cylindrical shape. The angle of each cutting edge 63 of the cutting edge 62 is about 20 to 60 degrees, particularly about 30 to 45 degrees. With this cutting edge 62, the cutting edge 63 cuts sharply into the film, so that the film can be efficiently cut.

  The suction cup 65 shown in FIG. 12 includes a small cup-shaped suction chamber 67 in the upper part of the main body portion in addition to the normal cup-shaped main body portion 66. The entire suction cup 65 is made of an elastic material such as synthetic rubber or natural rubber and is integrally formed in a substantially gourd shape. In this case, when the upper end is pressed downward, the main body 66 is elastically deformed flat and the suction chamber 67 is also elastically deformed flat. When the pressing force is weakened, the film can be strongly adsorbed by the negative pressure generating action of both the main body 66 and the suction chamber 67. In addition, a difference can also be given to the pressing force when the main-body part 66 and the suction chamber 67 deform | transform. For example, if the pressing force when the main body 66 is deformed is weaker than that of the suction chamber 67, the main body 66 is attracted only by the deformation of the main body 66 in a normal operation, and the strong pressing force is required when strong suction is required. The suction chamber 67 can be deformed and adsorbed with a strong force. On the other hand, if the pressing force required for the deformation of the suction chamber 67 is made weaker than that of the main body portion 66, it is adsorbed only by the deformation of the suction chamber 67 without changing the shape of the main body portion 66 during normal operation. Can do.

  In the suction cutter 35 of FIG. 4, a spiral protrusion 38 is provided on the outer surface of the support bar 16, and a spiral concave groove 39 is provided on the inner surface of the boss 37 of the cutting blade holding member 36. As described above, a protrusion 38 a that slides in the groove 39 can be provided instead of the protrusion 38. Although two grooves 39 are provided, only one groove may be provided. In that case, the projection 38a may be provided at one location. Further, the concave groove 39 does not need to rotate more than one round when the support bar 16 is moved up and down, and for example, it is sufficient to rotate about 30 to 120 degrees, particularly about 90 degrees. This also applies to the suction cutter 35 of FIG.

  In the embodiment of FIG. 1 and the like, basically, the support rod that supports the suction cup and the pressing member that presses the film when the film is pulled up by the suction cup are relatively operated, and the pressing member is pressed by the biasing force of the spring. The structure that pulls up the suction cup with the reaction force is adopted. However, it is also possible to adopt a configuration in which the suction cup is pressed and lifted by hand without using a spring. In that case, as shown in FIGS. 2 and 7, it is preferable to expose the pressing member 27 so that it can be pressed from the outside. Such a configuration in which the spring can be omitted is advantageous in that the number of parts is reduced and the manufacturing cost is reduced.

  In the embodiment such as FIG. 1, the suction cutter for breaking the packaging film of the commodity has been described. However, the suction cutter of the present invention is not limited to the suction cutter for these packaging films. It can also be used in a surgical suction cutter capable of cutting only the skin without damaging the skin, and a food processing suction cutter capable of cutting only the epidermis without damaging the fish eggs or internal meat. A laser scalpel can be used as a means for making a cut in such an animal or plant epidermis (film). For example, when the suction means lifts the epidermis and releases it from the internal tissue, the laser knife preferably irradiates the lifted epidermis from the lateral direction to make a cut.

  In the embodiment of FIG. 1 and the like, a single device or a portable device that is manually operated by a user in hand is used. However, a fixed type used in connection with a compressor or a laser generator or a form of equipment is used. You can also
