Description

The present invention relates to a rubber separation device for a rubber roller and a method for separating the rubber, and particularly to a rubber separation device for a rubber roller and a rubber separation thereof that can easily and reliably separate and remove a rubber material from a metal shaft. It is about the method.

Conventionally, a platen roller facing the thermal head in the printing section of a printer, or various guide rollers and other rubber rollers in the transfer path of printing paper, for example, a stainless steel metal shaft, NBR (nitrile rubber) or fluorine rubber Etc. are made into a product by injection molding.
Such a rubber roller is separated into a metal shaft and a rubber material after the use is discarded or when there is a defect as a molded product, and the metal shaft is particularly recycled.

As a conventional separation process, the rubber material is removed from the metal shaft using a cutter or the like.
The fluoro rubber is relatively easy to separate by hand using a cutter as described above because of its good tearability, but NBR has poor tearability and separation. In addition to the time required for processing, there is a problem that the manual shaft is dangerous, and the metal shaft is easily damaged due to the manual operation.
In any case, if the rubber material can be separated from the used or defective rubber roller in a short time regardless of the material of the rubber material, the metal shaft and the rubber material can be recycled. Therefore, there is a problem that simplification of the separation process is required.

    In the present invention, since the rubber material is cut and separated from the metal shaft using a circumferential blade that can be separated and closely attached to the outer peripheral portion of the metal shaft, and a radial blade, regardless of manual operation, A rubber roller rubber separating device and a method for separating the rubber material that can mechanically easily and reliably separate a rubber material from a metal shaft have been realized.

Next, a rubber roller rubber separating apparatus 1 and a rubber separating method thereof according to an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a partial cross-sectional plan view of a rubber separating device 1 for a rubber roller, and a rubber roller 2 is attached to a metal shaft 3 having a circular cross section and a cylindrical and integrally attached around the metal shaft 3. And a rubber material 4.
The rubber separating device 1 of the rubber roller 2 separates the rubber material 4 in the rubber roller 2 from the metal shaft 3, and includes a base table 5, a drive cylinder 6 fixed to the base table 5, and a side surface of the drive cylinder 6. The expansion and contraction pin 8 attached to the pin mounting base 7 fixed to the base base 5 at the position, the first movable base 9, the second movable base 10, the circumferential blade 11, and the radial direction Blade 12.

The drive cylinder 6 is an arbitrary type of cylinder, such as an air cylinder or a hydraulic cylinder. In particular, if an air cylinder is employed, the drive cylinder 6 can be powered in a place where an arbitrary air pressure can be secured by a compressor (not shown). Even if it is not, it can be easily installed only by connecting to the piping.
The cylinder movable portion 13 of the drive cylinder 6 has a first movable portion 9, which can be reciprocated together with the first movable portion 9 in the axial direction of the rubber roller 2 by operating the hand valve 14.
For example, if the hand valve 14 is rotated around the valve shaft 15 of the hand valve 14 in the clockwise direction in FIG. 1 (solid arrow in the figure), the cylinder movable unit 13 is moved from right to left in FIG. It can move in the direction (forward movement) (solid line arrow in the figure).
Further, if the hand valve 14 is rotated counterclockwise in FIG. 1 (the dotted arrow in the figure), the cylinder movable portion 13 can be moved (returned) from left to right in FIG. Yes (dotted arrow in the figure).
Thus, the cylinder movable portion 13 of the drive cylinder 6 can drive the first movable base 9 and reciprocate it in the direction of the second movable base 10.

    The expansion and contraction pin 8 is located at a position different from the cylinder movable portion 13 of the drive cylinder 6, that is, on the side of the side of the drive cylinder 6 and fixed to the base base 5. 13 is arranged so as to be relatively fixed with respect to 13, and its axial direction is arranged along the axial direction of the drive cylinder 6 or the rubber roller 2.

FIG. 2 is a right side view of the first movable base 9 in the rubber separating apparatus 1 for rubber rollers, and FIG. 3 is a left side view of the second movable base 10 in the rubber separating apparatus 1 for rubber rollers.
As described above, the first movable base 9 is attached to the cylinder movable portion 13 of the drive cylinder 6, and the circumferential blade 11 and the radial blade 12 are detachably attached to the tip portion thereof. The circumferential blade 11 reciprocates so as to engage and disengage with the expansion and contraction pin 8.

The second movable table 10 is formed on the surface of the base table 5 along a slide groove 16 (FIG. 1) formed in the base table 5 in parallel with the drive cylinder 6 with a gap between the drive cylinders 6. 9 can be reciprocated with respect to the lever 9, and the operation lever 17 is rotated around its lever shaft 18 so as to be fixed and movable in the slide groove 16, so that an arbitrary adjustment position on the base table 5 can be obtained. Can be set.
For example, the operating lever 17 is turned counterclockwise around the lever shaft 18 and set to the first turning position (solid line in FIG. 1), and the second movable base 10 is moved to the slide groove 16 ( The second movable base 10 is moved along the drive cylinder 6), rotated in the clockwise direction and set at the second rotational position (the phantom line in FIG. 1), and the second movable base 10 is moved to the first movable base. 9 (cylinder movable part 13) can be fixed, and its position is set according to the length of rubber roller 2 (metal shaft 3) set between first movable base 9 and second movable base 10. It can be adjusted.

More specifically, the first movable base 9 is attached to the cylinder movable portion 13 of the drive cylinder 6 and the one end portion 3A of the metal shaft 3 is detachable.
The second movable base 10 reciprocates in the axial direction of the rubber roller 2 with respect to the first movable base 9, and the position of the second movable base 10 can be adjusted according to the length of the metal shaft 3. The other end 3B can be attached and detached.

4 is a side sectional view of the expansion / contraction pin 8, the circumferential blade 11 and the radial blade 12, and FIG. 5 is a view from the second movable base 10 side of the circumferential blade 11 and the radial blade 12. It is an axial side view.
In particular, as shown in FIG. 4, the expansion / contraction pin 8 has a base end fixing portion 19 fixed to the pin mounting base 7 and a pin main body 20, and the expansion / contraction pin 8 (pin main body 20) is In the direction in which the first movable base 9 faces the second movable base 10, the tip portion 20A of the pin body 20 is tapered.
In addition, a shaft fixing hole 21 is formed in the pin main body 20 so as to be open toward the second movable base 10, and the one end portion 3 </ b> A of the metal shaft 3 can be inserted and fixed in the shaft fixing hole 21.

The circumferential blade 11 is attached to the first movable base 9, and the inner peripheral surface of the circumferential blade 11 is expanded and contracted with the drive of the first movable base 9 (the tapered tip of the pin body 20). The size in the circumferential direction can be changed so as to expand and contract by contacting and separating the portion 20A), and the metal shaft 3 can be in close contact with the contracted configuration.
That is, the circumferential blade 11 includes a cylindrical base portion 22 that can be positioned on the outer periphery of the expansion and contraction pin 8 and a plurality of pieces (examples shown in the drawing) that are divided in the circumferential direction in the distal end direction of the base portion 22. Then, four unit circumferential blades 23 are provided.
In the example illustrated in FIG. 5, the unit circumferential blade 23 is divided into four equiangular intervals in the circumferential direction, and the boundary material 24 adjacent to each other has an inherent characteristic of the metal material of the circumferential blade 11 itself. It can shift to an open and closed state by elasticity. Of course, it can also be divided into arbitrary number of unit circumferential blades 23 at arbitrary angular intervals.

    That is, in the first position where the circumferential blade 11 is engaged with the expansion / contraction pin 8, the unit circumferential blade 23 is opened and expands larger than the diameter of the metal shaft 3, The circumferential blade 11 can fit the expansion / contraction pin 8 to the inner portion thereof. Further, in the second position where the disengaged state from the expansion / contraction pin 8 is in the disengaged state, the unit circumferential blade 23 is in the closed state, and is approximately the same diameter as the diameter of the metal shaft 3 (strictly speaking, the outer periphery of the metal shaft 3). By sliding in contact with the portion, the outer peripheral rubber material 4 shrinks to a diameter that can separate the metal shaft 3 from the metal shaft 3.

A radial blade 12 extending in the radial direction of the rubber roller 2 (metal shaft 3) is positioned at the center of the outer periphery of the unit circumferential blade 23.
That is, the radial blade 12 is attached to the first movable base 9 and is radially outward with a length sufficient to cut at least the thickness direction of the rubber material outward in the radial direction of the metal shaft 3 (example shown in the drawing). Then, they extend in a slightly inclined state so as to rise toward the base portion 22 of the circumferential blade 11.
The radial blade 12 is integrally formed with the circumferential blade 11 (unit circumferential blade 23), and the tip of the tip thereof coincides with the tip of the tip of the circumferential blade 11. In the axial direction of the rubber roller 2, it is located at the same position as the circumferential blade 11 with respect to the side end face of the rubber material 4.
Thus, the circumferential blade 11 and the radial blade 12 can be opposed to the rubber roller 2 from the side end surface side of the rubber material 4, and the rubber material 4 can be cut and separated in this facing posture.
Specifically, the circumferential blade 11 cuts off the rubber material 4 from the surface of the metal shaft 3, and the radial blade 12 removes the rubber material 4 in the axial direction of the metal shaft 3. The circumferential cutting blade 11 releases the stress that pushes the rubber material 4 away from the outer surface of the metal shaft 3, and the cutting action by both cooperates to release the rubber material from the metal shaft 3. 4. Smooth cutting and separation is realized.
In addition, as a material of the circumferential direction blade 11 and the radial direction blade 12, while having toughness on the whole, only the front-end | tip part (blade edge) has a predetermined sharpness thru | or rigidity is preferable.

Further, as shown in FIG. 2, the base portion 22 of the circumferential blade 11 is inserted into a bifurcated yoke portion 25 formed at the distal end portion of the first movable base 9, and the yoke portion 25 is released from tightening by a mounting bolt 26. By being possible, the circumferential blade 11 can be attached to and detached from the first movable base 9.
Since the expansion / contraction pin 8 can also be attached to and detached from the pin mounting base 7, the expansion / contraction pin 8 in the pin mounting base 7 and the first movable base 9 together with the expansion / contraction pin 8, if necessary. 8. The circumferential blade 11 and the radial blade 12 can be replaced with ones that match the diameter of the metal shaft 3.

Further, as shown in FIGS. 1 and 3, a shaft receiving portion 29 of a shaft mounting member 28 (see a perspective view taken along an imaginary line in FIG. 1) removably attached to the top of the second movable base 10 by a mounting bolt 27. When the diameter of the rubber roller 2 is changed, particularly when the diameter of the metal shaft 3 is different, the shaft mounting member 28 in the second movable base 10 can be replaced with one that matches the diameter. it can.
When the size of the rubber roller 2, for example, the length of each rubber roller 2 is different, the rubber roller 2 is adjusted by adjusting the relative position of the second movable base 10 with respect to the first movable base 9. It can be set between one movable table 9 and the second movable table 10.

    In the present invention, the radial blade 12 can be formed separately from the circumferential blade 11 when attached to the first movable base 9.

    Further, FIG. 6 is a cross-sectional side view of an essential part showing a modification of the relative positional relationship between the circumferential blade 11 and the radial blade 12, and the radial blade 12 is formed by the rubber roller 2 as shown in the drawing. In this axial direction, the circumferential blade 11 is protruded in the direction of the rubber material 4 so as to be slightly closer to the rubber material 4 than the circumferential blade 11 by the cutting edge distance D in the figure. Prior to this, the radial blade 12 first cuts the rubber material 4 in the radial direction, so that the cutting and separating action of the rubber material 4 by the circumferential blade 11 can be facilitated.

The operation of separating and removing the rubber material 4 from the metal shaft 3 of the rubber roller 2 in the rubber separating device 1 of the rubber roller having such a configuration will be described with reference to FIGS. 1 and 7 in particular.
FIG. 7 is a flowchart showing the procedure of the rubber separation method of the rubber roller according to the present invention. In step S1, the hand valve 14 (FIG. 1) is rotated counterclockwise, and the cylinder movable part in the drive cylinder 6 is operated. The 13 first movable bases 9 are initially set at the left end position.
By this initial setting, the pin main body 20 of the expansion / contraction pin 8 is fitted into the base portion 22 (FIG. 4) of the circumferential blade 11 in the first movable base 9, and the tapered tip portion 20A of the pin main body 20 is inserted. As a result of pushing out each unit circumferential blade 23 of the circumferential blade 11, the boundary 24 is opened, the unit circumferential blade 23 is released, and the circumferential blade 11 is one end of the metal shaft 3 of the rubber roller 2. 3A can be accepted.

That is, in step S2, one end 3A of the metal shaft 3 is inserted and set into the shaft fixing hole 21 of the expansion / contraction pin 8 via the circumferential blade 11 and attached.
In step S3, the operation lever 17 (FIG. 1) is turned to the state indicated by the solid line in FIG. 1 so that the second movable base 10 can be moved by the slide groove 16 of the base base 5 and the second movable base 10 is moved. The movable base 10 is moved in the direction of the other end 3B of the metal shaft 3 (rightward in FIG. 1), and the other end 3B of the metal shaft 3 is inserted into the shaft receiving portion 29 of the shaft mounting member 28. Then, the operating lever 17 is rotated in the state indicated by the phantom line in FIG.

In step S4, when the hand valve 14 is turned clockwise, the cylinder movable portion 13 of the drive cylinder 6 moves to the left in FIG. 1, that is, the second movable base 10 along the axial direction of the rubber roller 2. Starts moving in the direction (solid arrow in FIG. 1), and disengages from the distal end portion 20A of the expansion / contraction pin 8 as the cylinder movable portion 13 of the drive cylinder 6 is driven in the direction of the second movable base 10. The circumferential blade 11 (four unit circumferential blades 23) is contracted to be brought into close contact with the outer periphery of the metal shaft 3.
Further, in step S 5, the rubber material 4 is cut and separated from the metal shaft 3 by the circumferential blade 11 and the radial blade 12 as the first movable table 9 moves in the direction of the second movable table 10. .

    The cutting of the rubber material 4 by the circumferential blade 11 and the radial blade 12 is performed by separating or cutting the rubber material 4 by the circumferential blade 11 in the circumferential direction of the metal shaft 3 and the diameter of the metal shaft 3 in the radial direction. Since the cutting or cutting of the rubber material 4 by the directional blade 12 is performed at the same time, the circumferential direction is accompanied by driving along the axial direction of the rubber roller 2 of the cylinder movable portion 13 in the driving cylinder 6. The rubber material 4 can be mechanically and reliably separated from the metal shaft 3 by the blade 11 and the radial blade 12.

When the first movable table 9 reaches the second movable table 10 and the rubber material 4 of the rubber roller 2 is cut and separated for all the lengths, the circumferential blade 11 and the radial blade 12 are moved in step S6. The first movable base 9 has a contact with the contact side surface 28A (the side surface on the first movable base 9 side) of the shaft mounting member 28 in the second movable base 10 and stops.
Therefore, it is desirable that the shaft mounting member 28 is made of a hard synthetic resin such as hard urethane, which is different from the metal material of the circumferential blade 11 and the radial blade 12.
Of course, depending on the length of the rubber roller 2 (metal shaft 3), control by a limit switch (not shown) that detects the movement of the first movable base 9 to the set position, or the set position is set in advance. Other electrical controls such as are also possible.

    In step S7, by rotating the hand valve 14 counterclockwise, the drive cylinder 6 is driven to move the first movable base 9 back to the original position (right end position in FIG. 1). By rotating the lever 17 and moving the second movable table 10 to the left position in FIG. 1 with respect to the first movable table 9, the metal shaft 3 of the rubber roller 2 is moved to the first movable position. It removes from the stand 9 and the 2nd movable stand 10, and the isolation | separation operation | work of the rubber material 4 is complete | finished.

    Thus, the rubber material 4 of the rubber roller 2 is mechanically and reliably cut from the metal shaft 3 only by the driving operation of the driving cylinder 6 by the hand valve 14 and the adjustment set of the second movable base 10 by the operating lever 17. Can be separated.

In the flowchart of FIG. 7, the order of step S2 and step S3 may be any order.
That is, the other end 3B of the metal shaft 3 can be inserted into the shaft receiving portion 29 first, and then the one end 3A of the metal shaft 3 can be inserted into the shaft fixing hole 21.

As described above, the separation or separation of the rubber material 4 from the metal shaft 3 is performed safely and quickly in a short time using the circumferential blade 11 and the radial blade 12, unlike the conventional manual operation. This is possible, and the recycling process of defective products can be quickly performed in the manufacturing process of the platen roller or other rubber roller 2, so that the metal shaft 3 is not wasted.
Furthermore, if an air cylinder is employed as the drive cylinder 6, a simple separation process can be performed without using a power source.
