In addition, the replacement blade can be attached and detached without touching the replacement blade directly, which is excellent in convenience and usability.

The best mode for carrying out the present invention will be described. The replaceable blade loader / detacher for a blade includes a replaceable blade remover section and / or a replaceable blade mounting section. The replaceable blade remover part and the replaceable blade mounting part can be provided integrally. Moreover, it is good also as a separate body each isolate | separated. In the replaceable blade remover, a replaceable blade (usually a used replaceable blade) detachably attached to the blade is removed from the blade body. The replaceable blade remover for removing the replaceable blade includes a replaceable blade storage chamber that stores the replaceable blade, a replaceable blade insertion port that communicates with the replaceable blade storage chamber, and a replaceable blade pressing member that presses the replaceable blade disposed in the replaceable blade storage chamber. Is provided. Therefore, the replacement blade of the blade is inserted into the replacement blade storage chamber from the replacement blade insertion port, and the replacement blade of the blade disposed in the replacement blade storage chamber is pressed by the replacement blade pressing member, thereby preventing the movement of the replacement blade in the front-rear direction. In this state, the blade body is pulled out from the replacement blade insertion port, and the replacement blade is removed from the blade (removal of used replacement blade).

In the replacement blade mounting portion, a replacement blade (usually an unused replacement blade) is mounted on the blade body. The replacement blade mounting unit for mounting the replacement blade includes a replacement blade loading chamber for loading the replacement blade, a replacement blade insertion port leading to the replacement blade loading chamber, and a replacement blade holding member for holding the replacement blade of the replacement blade loading chamber. . The blade replacement chamber is loaded with blade replacement blades inserted from the blade insertion port. The blade of the blade disposed in the blade loading chamber is held by the blade holding member, the blade blade is inserted into the sheath from the blade insertion opening at the rear end of the blade, and the blade is mounted. The blade is attached so that the blade is removed from the replacement blade insertion opening (attachment of unused replacement blade).

In a replaceable blade loading / unloading device for blades that has a replaceable blade remover and a replaceable blade mounting portion integrated, the replaceable blade insertion port of the replaceable blade remover and the replaceable blade insertion port of the blade mounting portion are inserted with one elongated blade. The mouths were arranged in different directions such as a horizontal direction and a cross shape with the other elongated replacement blade insertion port as a vertical direction. Since the replacement blade insertion ports are arranged in different directions, it is possible to reliably perform operations with different properties such as removal of the replacement blade and mounting of the replacement blade. There are no restrictions on the direction and arrangement of the opening of the replacement blade insertion opening.

A protective member that shields contact from at least one side is provided to the rear end portion of the replaceable blade including the blade body exposed to the outside from the replaceable blade insertion port so as to be foldable or foldable. With respect to the replacement blade mounted on the replacement blade remover and the replacement blade mounted on the blade mounting portion, the rear end portion (including the blade body and the blade insertion opening of the sheath portion) is exposed. A protective member for blocking contact from at least one side is provided for such a rear end portion. The structure of the protective member is arbitrary, such as a member that covers the entire rear end (but can be attached or detached) or a member that blocks only the side. Thereby, the approach to the rear end portion of the replaceable blade is blocked or blocked, and the rear end portion of the replaceable blade is protected.

As described above, the replaceable blade loader / detacher of the blade has a function of removing the replaceable blade and / or a function of attaching the replaceable blade, and removes the replaceable blade by the replaceable blade remover and attaches the replaceable blade by the replaceable blade mounting portion. Can be done. In either case, the replacement blade can be removed and / or attached without touching the replacement blade directly. Although the replaceable blade remover part and the replaceable blade mounting part are provided integrally, they may be separated. The replaceable blade remover part and the replaceable blade mounting part are used in combination, but may be used alone.

Embodiments of the present invention will be described below with reference to the accompanying drawings. First, the structure of a ridge and its replacement blade will be described. Note that the blade is not limited to the ridge 30. The scissors are pivotally attached so that a pair of scissors constituting members 31 can be opened and closed in a crossing manner. The front side of the shaft portion 32 is a pair of blades 33, and a blade is detachably attached to the blades 33. In other words, the used replacement blade with reduced cutting is removed from the blade 33, and an unused replacement blade is attached to the blade 33. The replaceable blade 25 has the maximum width (height) and thickness at or near the rear end portion 35, and is narrower from the rear end portion 35 toward the front end portion 36. The replaceable blade 25 includes a blade body 37 having a blade edge 14 and a sheath 39 provided integrally with the blade body 37. For a blade that has not been mounted, if the blade 33 is forcibly inserted into the sheath 39 of the blade from the blade insertion port 27, the blade is mounted on the blade (mounting of a blade). In addition, when the blade 33 is forcibly pulled out from the blade portion 39 of the replacement blade, the replacement blade is removed from the rod main body (blade 33) (removal of the replacement blade). The basic structure of the above ridges and their replacement blades is known (for example, Patent Document 1). In addition, the uneven | corrugated | grooved part 26 is formed in the surface of the rear-end part 35 of the replaceable blade in which the width | variety and thickness of a replaceable blade become the maximum, or its vicinity, specifically, the sheath part 39 provided in the blade body 37. FIG.

In the blade replacement / removal device 50 for a blade according to the first embodiment, a blade replacement remover 1 and a blade mounting portion 2 are integrally provided. A replaceable blade is detachably mounted on the scissors (main body), and the replaceable blade 25 mounted on the replaceable blade remover 1 is removed from the scissors main body. Note that the heel body refers to the portion of the jar excluding the replacement blade. The replaceable blade remover 1 has a box shape including an upper wall 51, a bottom 52, front and rear walls 53 and 23, and left and right side walls 59, and a replaceable blade storage chamber 3 is formed therein. The replaceable blade storage chamber 3 stores the removed replaceable blade, but the replaceable blade storage chamber 3 is also a space in which the replaceable blade 25 is disposed when the replaceable blade is removed.

A replaceable blade insertion port 5 is formed at the upper part of the replaceable blade remover 1 slightly backward from the front wall. An elongated replacement blade insertion slot 5 is arranged in the horizontal direction. The replaceable blade insertion port 5 communicates with the replaceable blade storage chamber 3, and the replaceable blade attached to the main body is inserted into the replaceable blade storage chamber 3 from the replaceable blade insert port 5. The replaceable blade moves in the length direction of the replaceable blade remover 1, that is, in the front-rear direction, and is inserted into the replaceable blade storage chamber 3. A linear first restriction rail 11 extends from the replacement blade insertion port 5 to the rear wall on the inner surface of the upper wall of the replacement blade storage chamber 3. The replacement blade sheath 39 and the first regulation rail 11 are in contact with each other, and the displacement of the replacement blade disposed in the replacement blade storage portion 3 is prevented.

The replaceable blade insertion port 5 is provided with a planar support base 6 on which the replaceable blade is placed. The support base 6 continues from the front end of the replaceable blade remover 1 to the replaceable blade insertion port 5, and further extends rearward beyond the replaceable blade insert port 5. The end portion is in the replaceable blade storage chamber 3 and extends to a position corresponding to a replaceable blade pressing member A described later. In addition, it is preferable that the edge part of the support stand 57 is set to the substantially middle part of the replaceable blade storage chamber 3 so that the removed replaceable blade may easily fall into the replaceable blade storage chamber 3 due to its own weight or the like. The portion of the support base 6 that extends rearward from the replacement blade insertion opening 5 is formed by a horizontal plate that is bent and extends rearward from the upper front end portion while the front end portion of the bottom portion 52 rises in the vertical direction. The replaceable blade is disposed at the replaceable blade storage chamber 3 while the rear end portion 35 or the vicinity thereof is supported by the support base 6. The support base 6 also has a function of guiding the replacement blade inserted from the replacement blade insertion port 5.

A replacement blade pressing member A is provided on the upper wall slightly backward from the replacement blade insertion port 5. The replaceable blade pressing member A has a function of pressing the replaceable blade disposed in the replaceable blade storage chamber 3 and preventing at least the movement of the replaceable blade in the front-rear direction. The replacement blade pressing member A is not prevented from having other functions. The replaceable blade pressing member A takes the form of a claw piece having a connection portion with the upper wall 51 as a base end portion 7 and a distal end as a free end. The replaceable blade pressing member A is bent and displaced with the base end portion 7 as a base point due to the applied external force, while the elastic restoring force due to the bending works by the release of the external force and returns to the original position.

In the illustrated case, when the replaceable blade pressing member A protruding from the surface of the replaceable blade storage chamber 3 is pushed down, the replaceable blade pressing member A is bent and displaced toward the inside of the replaceable blade storage chamber 3 from the base end 7. Due to this displacement, the replaceable blade 25 of the replaceable blade storage chamber 3 is pressed (normally, the back surface of the replaceable blade pressing member A comes into contact with the replaceable blade), and movement of the replaceable blade in the front-rear direction is prevented. Or the uneven | corrugated | grooved part 55 formed in the back surface 29 of the replaceable blade pressing member A and the uneven | corrugated | grooved part 26 formed in the surface of a replaceable blade are in the position which opposes, and the front-back direction of a replaceable blade by engagement of both the uneven | corrugated parts 55 and 26 Movement is prevented. In this state, when the scissors main body is pulled out from the replacement blade insertion slot 5, the replacement blade is removed from the blade 53. On the other hand, when the pressing is stopped, the replacement blade pressing member A returns to the original position by the elastic restoring force, and the pressing by the replacement blade pressing member A or the contact with the replacement blade is released. The removed replacement blade loses its balance and falls by its own weight from the support base 6, and the used replacement blade is stored in the replacement blade storage chamber 3.

In the replaceable blade mounting portion 2, the replaceable blade 25 is mounted on the bag main body. The replaceable blade mounting portion 2 has the replaceable blade remover portion 1 as a main body and is disposed on the left and right side walls 59 thereof. The replaceable blade mounting portion 2 includes an upper side wall 60 and a lower side wall 61, an inner side wall 65, an outer side wall 63, and a front side wall 66, and a replaceable blade loading chamber 9 is formed therein. An unused replacement blade is loaded into the replacement blade loading chamber 9. An elongated replacement blade insertion port 15 is formed in the vertical direction on the rear end side, and the replacement blade insertion port 15 communicates with the replacement blade loading chamber 9. The replacement blade insertion port 15 is open to the rear side, and the replacement blade (unused replacement blade) is inserted from the rear replacement blade insertion port 15 into the replacement blade loading chamber 9 (in the case of the replacement blade remover). Is the opposite direction). The replaceable blade insertion port 15 may be opened in any of the front and rear directions, or may be opened in different directions. As for the inserted replacement blade, the front-end | tip part 36 contact | abuts with the front side wall 66 (inner surface), and the approach is prevented. That is, the front side wall 66 serves as a stopper to restrict the position of the replaceable blade in the front-rear direction, and the inserted replaceable blade is disposed at a predetermined position in the replaceable blade loading chamber 9.

In the replaceable blade loading chamber 9, the position of the replaceable blade is further regulated. First, on the inner surface of the outer wall 63, the first restriction rail 20 continuously extends from the replacement blade insertion port 15 to the front side wall 66, and restricts the loaded replacement blade 25 from the blade tip 14 side. In other words, the blade is in contact with the linear first rail 20 at the blade edge 14 side (relatively close to the blade edge 14) of the sheath 39, thereby preventing displacement of the blade disposed in the blade replacement chamber 9. To do. Since the surface of the replaceable blade (the surface of the sheath portion 39) is inclined toward the blade edge 14 on the blade edge 14 side, the upper surface of the first regulating rail 20 that is in contact is also inclined correspondingly (see FIG. 24).

Next, the 2nd control rail 21 controls a replaceable blade from the back part 29 side. In the replaceable blade, the blade edge 14 of the blade body 37 extends linearly, but the back portion 29 is inclined from the rear end portion 35 to the front end portion 36 (see FIG. 4). The width becomes narrower from the middle part to the tip part 36 of the replaceable blade 25, and the stability in arrangement becomes a problem. The second restriction rail 21 formed on the inner surface of the outer wall 63 starts from the upper wall and extends in an inclined manner toward the linear first restriction, and the tip is slightly spaced from the first restriction rail 20 (FIG. 8). reference). The second regulation rail 21 abuts on the back 29 of the replaceable blade disposed in the replaceable blade loading chamber 9, particularly the back 29 in the front portion, and the displacement of the replaceable blade (the tip portion 36 and the like) in the replaceable blade loading chamber 9 is shifted. To prevent.

A bulging portion 10 is formed on the inner wall 65 of the replaceable blade loading chamber 9 (also the left and right side walls 59 of the replaceable blade remover portion 1 which is the main body). The bulging part 10 regulates the replacement blade of the replacement blade loading chamber 9 from the blade body 37 side. The bulging portion 10 is a planar portion that slightly protrudes from the inner wall. The bulging portion 10 is formed at a position substantially corresponding to the blade 37 of the replaceable blade to be disposed. Further, it is preferable that the size and shape correspond to the blade 37 of the replaceable blade. In the replaceable blade loaded in the replaceable blade loading chamber 9, the blade body 37 comes into surface contact with the bulging portion 10 and is stably held by the frictional force thereof.

The replaceable blade loading chamber 9 includes a replaceable blade holding member B. The replaceable blade holding member B holds the replaceable blade in the replaceable blade loading chamber 9 and prevents at least the loaded replaceable blade from dropping off. The replaceable blade holding member B is provided in the outer wall 63 of the replaceable blade loading chamber 9 slightly retracted from the replaceable blade insertion port 15. The replaceable blade holding member B takes the form of a claw piece having a connection portion with the outer wall 63 as a base end portion 17 and a distal end as a free end. The replaceable blade holding member B is bent and displaced with the base end portion 17 as a base point due to the applied external force, while the elastic restoring force due to the bending works by the release of the external force and returns to the original position.

In the case of illustration, the back surface 24 of the replaceable blade holding member B protrudes into the replaceable blade loading chamber. Then, when it contacts the replaceable blade inserted into the replaceable blade loading chamber 9, the replaceable blade holding member B which bends with the base end portion 17 as a base point is displaced to the outside of the replaceable blade load chamber 9, and the displaced replaceable blade holding member B is displaced. Is held in an elastic contact state. Or the uneven | corrugated | grooved part 56 of the back surface of the replaceable blade holding member B opposes the uneven | corrugated | grooved part 26 of the surface of a replaceable blade, and a replaceable blade is hold | maintained by engagement of both the uneven | corrugated parts 56 and 26. This prevents at least the replacement blade from falling out of the replacement blade loading chamber 9.

The replacement blade 25 loaded in the replacement blade loading chamber 9 has a rear end portion 35 (including the blade body 37 and the blade insertion port 27 of the sheath) exposed from the replacement blade insertion port 15. The rear end portion 35 is provided with a protective member 13 that blocks contact from at least one side. The protective member 13 has a plate-like outer protective piece 11 continuously extending rearward from the outer wall 63 of the replaceable blade mounting portion 2 (replacement blade loading chamber 9), and the rear portion of the upper and lower side walls 60, 61 with the groove portion 4 interposed therebetween. And an upper and lower protective piece 12 extending in the vertical direction. Both the outer protective piece 11 and the upper and lower protective pieces 12 are plate-shaped. The outer protective piece 11 blocks the approach to the rear end portion 35 of the replaceable blade from the side, and the upper and lower protective pieces 12 blocks the approach to the rear end portion 35 of the replaceable blade from the vertical direction. The shape and structure of the protective member are arbitrary.

The protective member 13 can be bent or broken off. The bending or folding direction is the outer side opposite to the rear end portion 35 of the replaceable blade, and in the case shown in the drawing, the protective member 13 can be folded sideways from the groove portion 4 so that the tip end portion 22 is sandwiched between the fingertips ( (See FIGS. 11 and 12). Similarly, it can be bent (not shown). There is nothing to shield the rear end portion 35 of the replaceable blade, and the replaceable blade held in the replaceable blade loading chamber 9 is mounted on the scissors main body with the blade insertion opening 27 at the rear end portion exposed. That is, when the blade 33 is forcibly inserted into the sheath 39 from the blade insertion opening 27 opened at the rear end of the replacement blade with respect to the replacement blade in the replacement blade loading chamber 9, the replacement blade 25 is attached to the blade 33. Installed (replacement blade installation). The scissors main body to which the replaceable blade is mounted is removed from the state held by the replaceable blade holding member B and taken out from the replaceable blade insertion port 15 in the replaceable blade mounting portion 2.

The replaceable blade loader / detacher of the blade of Example 2 is provided with a replaceable blade remover portion 1 and a replaceable blade mounting portion 2 as separate bodies. The replaceable blade remover unit 1 and the replaceable blade mounting unit 2 of the replaceable blade loader / detacher A take a separate and independent form, and the replaceable blade remover unit 1 and the replaceable blade mounting unit 2 are used in combination. In the replaceable blade remover 1, the replaceable blade mounted on the scissors is removed from the scissors main body, and in the replaceable blade mount 2, a replaceable blade is newly mounted on the scissors main body.

As for the replaceable blade remover portion, in FIG. 17, the replaceable blade remover portion 1 includes a base 70 having a flat upper surface and a lid portion 71 pivotally attached to the rear end of the base 70. The lid portion 71 opens and closes around the shaft portion 72 and opens about 30 degrees at the maximum. When the lid 71 is closed, the lid 71 is supported in a substantially horizontal direction by an elastic support 73 projecting from the rear portion of the base 70, and a spare blade storage chamber as an internal space composed of the base 70 and the lid 71. 3 is formed. The replacement blade insertion port 5 at the upper front end of the lid portion 71 communicates with the replacement blade storage chamber 3. When the replaceable blade mounted on the ridge 50 is inserted into the replaceable blade storage chamber 3 from the replaceable blade insertion port 5, the distal end portion 36 of the replaceable blade comes into contact with the elastic support 73 (side surface) and the entry thereof is prevented. The replaceable blade 25 is disposed at a predetermined position in the replaceable blade storage chamber 3 by the position restriction in the front-rear direction by the stopper (elastic support 73). The base end portion 35 of the replaceable blade protrudes outward from the replaceable blade insertion port 5.

The lid portion 71 simultaneously serves as a pressing member, and presses the replaceable blade 25 to prevent the replaceable blade from moving in the front-rear direction. That is, when the lid portion 71 is pushed down, the elastic support body 73 in contact with the inner surface of the lid portion 71 is deformed into a slightly flat shape or a lowered shape. At the same time, the inner surface of the lid 71 comes into contact with the replaceable blade (the sheath 39) and presses the replaceable blade. In this case, the concavo-convex portion formed on the back surface of the lid 71 (upper wall), which is the replacement blade pressing member A, faces the concavo-convex portion 26 of the replacement blade (sheath portion 39), thereby engaging both the concavo-convex portions. To do. In addition, the uneven | corrugated | grooved part of the back surface of the cover part 71 in a present Example is the same as the uneven | corrugated | grooved part (corresponding part) of the replaceable blade press member A shown by FIG. This prevents the replacement blade from moving in the front-rear direction. In this state, when the scissors main body is pulled out from the replacement blade insertion slot 5, the replacement blade 25 attached to the scissors 30 is removed from the blade 33. The removed blade is placed in the blade storage chamber 3 as it is.

Then, after the replacer blade 25 of the replaceable blade storage chamber 3 is moved rearward until the tip 36 of the replaceable blade comes to the upper surface of the elastic support 73 by, for example, tilting the remover portion 1 appropriately, the cover portion 71 is opened. Take out the used replacement blade from the remover unit 1.

22 and 23, the replaceable blade mounting portion 2 has a case shape, and the replaceable blade insertion port 15 at the front end communicates with the replaceable blade loading chamber 9 of the replaceable blade mount 2. The rear wall 67 serves as a stopper and restricts the position of the replaceable blade 25 inserted from the replaceable blade insertion port 15 in the front-rear direction. A first restricting rail 20 extending from the replaceable blade insertion port 15 to the rear wall is formed on the inner surface of the upper wall of the replaceable blade loading chamber 9, and the blade edge 14 side of the sheath 39 of the replaceable blade is in contact with the first restricting rail 20, Prevents blade misalignment.

The replaceable blade holding member B holds the replaceable blade loaded in the replaceable blade loading chamber 9. This holding function is the same as that of the first embodiment. The replaceable blade holding member B takes the form of a claw piece whose base end portion 17 is a connection portion with the upper wall 69. The back surface 27 of the replaceable blade holding member B protrudes into the replaceable blade loading chamber 9 (see FIG. 24), and when it contacts the replaceable blade 25 arranged in the replaceable blade loading chamber 9, the base end 17 is bent as a base point. The replaceable blade holding member B is displaced to the outside of the replaceable blade loading chamber 9. The replaceable blade is held in an elastic contact state by the displaced replaceable blade holding member B. Or the uneven | corrugated | grooved part 26 of the surface of a replaceable blade faces the uneven | corrugated | grooved part of the back surface of the replaceable blade holding member B, and both the engaging uneven | corrugated | grooved parts which oppose with the elastic force of the replaceable blade holding member B engage. Accordingly, at least the replacement blade disposed in the replacement blade loading chamber has a function of preventing the replacement blade from dropping off. In addition, the uneven | corrugated | grooved part of the back surface in the replaceable blade holding member B of a present Example is the same as the uneven | corrugated | grooved part (corresponding part) of the replaceable blade holding member B shown by FIG.

For the replaceable blade loaded in the replaceable blade loading chamber 9, if the scissors blade 33 is forcibly inserted into the sheath 39 from the blade insertion opening 27 that opens at the rear end of the replaceable blade, The replacement blade 25 is mounted (mounting of a replacement blade). The scissors main body to which the replacement blade is mounted is released from the replacement blade holding member B and taken out from the replacement blade insertion port 5.

The rear blade 35 of the replaceable blade loaded in the replaceable blade loading chamber 9 is exposed outside the replaceable blade insertion port 15. A cap 16 is detachably attached to the replacement blade insertion opening 15. The cap 16 protects the rear end portion 35 of the replaceable blade such as the blade body 37 protruding from the rear end portion 35. If the case-like replaceable blade mounting portion 2 is formed of a transparent material, the loaded state of the replaceable blade can be confirmed immediately.

The blade replacement / removal device for blades configured in this manner can be used not only as a replacement blade attachment / detachment device for medical and office bags, but also in a wide range of industrial fields including other blades.
