Abstract

A film cutting apparatus capable of easily cutting a roll-shaped film into a predetermined width is provided.
A cutter unit 7 is disposed at an upper portion of a film take-out port 5. At this time, the lower end (locking portion 15) of the pushing portion 21 is inserted into the locking portion insertion hole 11. By pushing the pushing portion 21 downward, the pushing portion 21 moves downward. For this reason, the blade moves downward and is exposed from the cutter unit 7. In this state, the fixing portion 13 is slid forward (in the film drawing direction). By doing in this way, the front-end | tip of the fixing | fixed part 13 fits in a groove | channel. Therefore, even if the pushing operation of the pushing portion 21 is finished, the state where the pushing member 21 is pushed downward is maintained. Next, the film 19 that has been previously drawn out is pulled out. Since the blade is disposed toward the roll side of the film 19, the film 19 passing through the cutter unit 7 is cut into a predetermined width by the blade.

Description

  The present invention relates to a film cutting apparatus capable of easily cutting a film.

  For example, in order to cut a film of a size to be used from a roll-shaped film having a predetermined width, such as Parafilm (registered trademark), it is necessary to use scissors or a cutter. For example, a film for sealing a beaker and a film for sealing a test tube have different sizes, and thus the user needs to cut the film into a predetermined size in advance.

  In order to cut out a film of a predetermined size from the roll film in this way, for example, a wrap film roll is rotatably housed in the container body, and a slide cutter unit is placed on the upper edge of the front plate of the container body. There is a wrap film storage case having a structure that is detachably mounted (Patent Document 1).

JP 2003-81279 A

  The slide cutter unit of Patent Document 1 has a blade portion slidably provided along a guide groove, and cuts the film in the width direction by sliding the blade portion. Therefore, a film having an arbitrary length can be drawn from the roll film and cut.

  On the other hand, as described above, the size to be cut varies depending on the use of the film. Therefore, it may be necessary to cut not only the length of the roll film but also the width direction. In this case, even if the slide cutter unit of Patent Document 1 is used, it is necessary to make a slit in the length direction with scissors, for example. In particular, when it is often used for sealing a small container or the like, it is necessary to slit a roll-shaped film into a plurality in the width direction.

  However, if this is done, the cutting width will not be constant, and there is a risk that the waste of the film will increase. In addition, since the drawing direction and the cutting direction coincide with each other and it is necessary to cut the film while pulling the film forward, it is difficult to cut the film straight. However, when a narrow roll is used from the beginning, the number of films that can be taken out from one roll is reduced, and the number of work steps such as cost increase and roll replacement work is increased. Moreover, since it is necessary to prepare a roll of multiple widths, there is a problem such as a roll storage place.

  This invention is made | formed in view of such a problem, and it aims at providing the film cutting device which can cut | disconnect a roll-shaped film easily to predetermined width.

  In order to achieve the above-described object, the present invention provides a main body part that accommodates a roll-shaped film, a film outlet that is formed in a part of the main body part and from which one end of the film can be taken out, and the film A cutter unit that is detachably attached to the take-out port, and the cutter unit is provided with a blade so as to face the drawing direction of the film. The film cutting apparatus is capable of cutting the film into a predetermined width.

  An elastic member is provided inside the cutter unit, and the blade is held by the elastic member in a state of being pulled back into the cutter unit, and the cutter unit is disposed in the film outlet, By pushing the pushing portion of the cutter unit, the blade protrudes from the cutter unit, and the cutter unit protrudes from the film in a state where the blade protrudes by moving the fixing unit provided on the main body unit. It is desirable to be fixed to the mouth.

  A mark indicating the position of the blade is provided on one side surface of the cutter unit, and the cutter unit is used as the film outlet so that the surface provided with the mark faces the drawing direction side of the film. By arranging, the blade may be in a direction facing the drawing direction of the film.

  According to the present invention, the film can be cut to a predetermined width only by pulling out the film by the cutter unit fixed to the film outlet. Therefore, the film can be easily cut with a certain width.

  Further, the blade of the cutter unit is normally housed inside the cutter unit. For this reason, for example, when the cutter unit is removed, the cutter unit can be handled safely. Further, when the cutter unit is fixed to the film outlet, the blade is maintained in a protruding state, so that the film can be cut reliably.

  Moreover, since the mark is provided on the front surface of the cutter unit, the direction of the blade of the cutter unit is not mistaken. Moreover, since the position of the blade can be known from the mark, the cutting width is not mistaken.

  According to the present invention, it is possible to provide a film cutting apparatus capable of easily cutting a roll-shaped film into a predetermined width.

The top view of the film cutting device 1. FIG.

  Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is an exploded perspective view showing a film cutting apparatus 1 according to an embodiment of the present invention. The film cutting device 1 mainly includes a main body unit 3, a cutter unit 7, a lid unit 17, and the like.

  The main body 3 has a substantially box shape with one surface opened, and can accommodate a roll-shaped film 19 therein. That is, the size of the main body is a size that can accommodate the unused film 19. A lid 17 is provided on one edge of the opening of the main body 3. The lid portion 17 can be opened and closed with respect to the main body portion 3. In addition, it becomes possible to visually recognize the roll accommodated by making the cover part 17 transparent.

  A film outlet 5 is formed in a part of the main body 3 near the opening. The film take-out port 5 is a part from which the end portion of the film 19 is drawn out while the film 19 is accommodated in the main body 3 and the lid 17 is closed. The upper surface of the film take-out port 5 is formed flat, and a hole 9 is provided in part. The hole 9 is a part into which a blade described later is inserted. Further, both side portions in the width direction of the film take-out port 5 are formed so as to protrude from both side surfaces of the main body portion 3. A locking portion insertion hole 11 is provided on the upper surface of a portion located outside the side surface of the main body portion 3.

  A cutter unit 7 is attached to the film outlet 5. The cutter unit 7 can be attached to and detached from the main body unit 3 (film outlet 5).

  2 is a cross-sectional view of the cutter unit 7. FIG. 2A shows a state in which the blade 25 is housed inside the cutter unit 7, and FIG. 2B shows the blade 25 protruding from the cutter unit 7. It is a figure which shows a state. Inside the cutter part 7, push-in parts 21 are provided so as to protrude from both sides of the cutter part 7. A locking portion 15 is provided at the lower end of the pushing portion 21. A groove 23 is provided on the inner surface side of the locking portion 15. The locking part 15 is a part that is inserted into the locking part insertion hole 11 of the main body part 3 (FIG. 1) and fixes the main body part 3 and the cutter part 7. The fixed state of the cutter unit 7 and the main body unit 3 will be described later.

  A spring 29 that is an elastic member is provided below the push-in portion 21. Therefore, in a normal state (for example, a state where the cutter unit 7 is removed from the main body unit 3), the pushing unit 21 is pushed back upward by the spring 29. A plurality of blades 25 are provided on the lower surface of the pushing portion 21 at a predetermined interval. A slit 27 is provided at a position corresponding to the blade 25 on the lower surface side of the cutter unit 7. As described above, the pushing portion 21 is normally pushed back upward, so that the blade 25 is also accommodated in the cutter portion 7. Therefore, the blade 25 is not exposed outside the cutter unit 7.

  As shown in FIG. 2B, when the pushing portion 21 of the cutter unit 7 is pushed downward against the spring 29 (in the direction of arrow A in the figure), the pushing portion 21 moves downward. Therefore, the blade 25 moves downward, and the blade 25 protrudes from the slit 27 to the outside. At the same time, the locking portion 15 moves downward. When the pushing of the pushing portion 21 is stopped, the pushing portion 21 is pushed back upward again by the spring 29. That is, the blade 25 and the locking part 15 move upward. In addition, as long as it is an elastic member, it may replace with the spring 29 and may use another member.

  Further, as shown in FIG. 1, a mark 31 is provided on the front surface of the cutter unit 7 (the surface on the drawing side of the film 19). The mark 31 indicates the direction of the cutter unit 7 and the position of the internal blade 25. That is, the direction of the blade 25 (the side to be cut) is opposite to the side on which the mark 31 is formed. A similar mark may be attached to the front surface of the main body 3.

  Next, the usage method of the film cutting device 1 is demonstrated. 3 is a plan view of the film cutting apparatus 1 before the cutter unit 7 is fixed, FIG. 4A is a side view, and FIG. 4B is a cross-sectional view taken along line BB in FIG. . By closing the lid 17, it is possible to prevent entry of foreign matter or the like into the main body 3.

  The cutter unit 7 is disposed at the upper part of the film take-out port 5. At this time, as shown in FIG. 4A, the lower end (locking portion 15) of the pushing portion 21 is inserted into the locking portion insertion hole 11. In this state, the groove 23 of the locking portion 15 is located above the fixed portion 13. Further, as shown in FIG. 4B, the blade 25 is housed inside the cutter unit 7 and is not exposed to the outside. A gap through which the film 19 can pass is formed between the cutter unit 7 and the film take-out port 5. In addition, by changing the thickness and shape of each pushing part 21 on both sides and changing the size of the corresponding locking part insertion hole 11 according to the thickness and shape of the pushing part 21, There is no mistake in the mounting direction.

  FIGS. 5A and 5B correspond to FIGS. 4A and 4B. As shown in FIG. 5A, first, the pushing portion 21 is pushed downward (in the direction of arrow C in the figure). By doing in this way, the pushing part 21 moves below. For this reason, as shown in FIG. 5B, the blade 25 moves downward, and the blade 25 is exposed from the cutter unit 7. At this time, since the hole 9 is provided at a position corresponding to the blade 25 of the film take-out port 5, the blade 25 is inserted into the hole 9.

  Further, as described above, when the push-in portion 21 moves downward, the locking portion 15 moves downward accordingly. That is, the locking portion 15 is inserted deeper into the locking portion insertion hole 11. At this time, the pushing portion 21 is pushed in until the groove 23 of the locking portion 15 has substantially the same height as the fixing portion 13.

  Next, in this state, as shown in FIG. 5A, the fixing portion 13 is slid forward (in the direction of drawing out the film) (in the direction of arrow D in the figure). By doing in this way, the front-end | tip of the fixing | fixed part 13 fits into the groove | channel 23. FIG. Therefore, even if the pushing operation of the pushing portion 21 is finished, the state where the pushing portion 21 is pushed downward is maintained. Accordingly, the cutter unit 7 is fixed to the main body unit 3. In order to remove the cutter unit 7, the reverse operation may be performed.

  Next, as shown in FIG. 6, the end portion of the film 19 that has been drawn to the outside in advance is pulled out (in the direction of arrow E in the figure). Since the blade 25 is disposed toward the roll side of the film 19 (that is, the direction facing the pulling direction), the film 19 passing through the cutter unit 7 is cut to a predetermined width by the blade 25. That is, the film 19 can be cut to a width corresponding to the width of the blade 25. Note that cutting in the width direction may be performed with scissors or the like.

  According to this embodiment, the film 19 can be cut into a predetermined width only by pulling out the film 19. Therefore, for example, even when many small films are used, a wide roll can be used. For this reason, cost can be reduced. Moreover, since the width is substantially constant, the width is not too narrow due to a cutting mistake or the like, and is not wasted.

  Moreover, since the cutter part 7 is detachable, it excels also in workability | operativity, such as exchange work of a roll, exchange of the blade 25, and a position change. Moreover, since the blade 25 is accommodated in the cutter part 7 when the cutter part 7 is removed, the handleability is good. Moreover, since the cutter part 7 is fixed to the main body part 3 in a state where the cutter part 7 protrudes, fixing work is also easy.

  Moreover, since the mark 31 is provided on the front surface of the cutter unit 7, the direction of the blade 25 is not mistaken. Further, the position of the blade 25 can be grasped by the mark 31.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea described in the claims of the utility model registration. It is understood that it belongs to the range.

  For example, in the above-described embodiment, three blades 25 are provided and the film 19 is divided into four. However, the number and arrangement of the blades 25 are not limited to the illustrated example. Moreover, the fixing method of the cutter part 7 and the main-body part 3, the sliding structure of the pushing part 21 of the cutter part 7, etc. are not restricted to the illustrated example, If the effect similar to this invention can be acquired, Other structures may be employed.
