Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a compression roller for an empty resin container crusher capable of reliably crushing a resin container such as a PET bottle, a manufacturing method thereof, and an empty resin container crusher provided with the compression roller.
[0002]
BACKGROUND OF THE INVENTION
  Resin containers such as PET bottles are popular because they are lightweight and flexible, they do not break like glass when dropped, and they have excellent chemical resistance, but they are recycled. When crushing, it is difficult to crush smoothly due to this flexibility. For example, even if it is crushed by hand, it has been felt that it will return due to repulsion, and the same phenomenon can be seen when it is crushed between a pair of compression rollers by an empty container crusher.
[0003]
  By the way, the present applicant has already applied for Japanese Patent Application No. 10-277847 “compression processing apparatus such as an empty can” as an empty container crusher, and when this is used, a resin container such as a PET bottle is used. Crushing is also possible. Although the technical principle has not been fully elucidated, since the compression roller side is also elastically deformed, the deformation can be transferred to a resin container such as a PET bottle on the side to be crushed, resulting in a preferable compression result. It is estimated to be.
  However, a plastic container such as a PET bottle that is discarded may be discarded with its lid sealed. In this case, the internal air is crushed to prevent deformation, and the compression deformation is performed smoothly. There is also no situation. For this reason, it is conceivable that a spike is planted in the compression roller and a hole is made in a resin container such as a PET bottle to release the internal air. However, the spike pin is actually increased on the rubber roller and the manufacturing cost is almost increased. It is extremely difficult to plant and manufacture without making them. For example, considering a general spike pin planting technique, a technique is generally assumed in which a spike insertion hole is provided on the pressing surface of a rubber roller and the spike pin is inserted into the insertion hole later. However, in this case, an excessive load tends to be applied to the implanted portion of the spike pin, and depending on the mode of use, the occurrence of a problem that the spike pin comes off is expected.
[0004]
[Technical issues for which development was attempted]
  The present invention has been made from such a background. First, a method for manufacturing a compression roller for an empty resin container crusher in which a spike pin is securely and inexpensively attached to the rubber roller side is established, and the resilience of the resin container is reduced.

And a drive motor 7. In this embodiment, only the upper roller unit 5 is provided with the spike pin 55 which is a feature of the present invention, and only the upper roller unit 5 is constituted by the compression roller for the empty resin container crusher according to the present invention. It is what is done.
[0013]
  The upper roller unit 5 in which the compression roller for the empty resin container crusher according to the present invention is used will be described. The upper roller unit 5 includes a first compression roller 51A according to the present invention driven by a drive motor 7 and a second compression roller 51B according to the present invention to which rotation is transmitted by the first compression roller 51A. It becomes as. In the following description, when the upper roller unit 5 and the lower roller unit 6 are not particularly limited to which compression roller, they are simply written as the compression roller R.
  The first compression roller 51 </ b> A and the second compression roller 51 </ b> B are rotatably supported side by side by the rotation shafts 52 </ b> A and 52 </ b> B with respect to the support frame 4 fixedly installed on the upper lid 21 of the storage box 2. Further, gears 53A and 53B are provided on the respective rotating shafts 52A and 52B. The drive gear 7a of the drive motor 7 and the gear 53A of the first compression roller 51A are engaged with each other, and the gears 53A and 53B of the first compression roller 51A and the second compression roller 51B are engaged with each other. The two compression rollers 51B rotate in the opposite directions.
[0014]
  The forms of the first compression roller 51A and the second compression roller 51B will be described. As shown in FIGS. 5 and 6, the first compression roller 51 </ b> A and the second compression roller 51 </ b> B have a bilaterally symmetric shape, and include a roller body 54 including a press part P, a receiving part C, and a hook part F, and the press part. And spike pins 55 implanted in P. The material of the roller body 54 of the first compression roller 51A and the second compression roller 51B is made of rubber, and the hardness of the rubber is such that when the force is applied above a certain level, it is deformed to release this force. Is set. Specifically, it is manufactured from NBR (acrylonitrile butadiene rubber) having a hardness of 70 as an example. It is also possible to change to various other appropriate elastic materials.
[0015]
  The spike pin 55 will be specifically described. The spike pins 55 are provided one by one in the press portion of the roller body 54, and when the opposing first compression roller 51A is planted in a portion offset to the left side, the second compression roller 51B is placed on the right side. Planted.
  Specifically, as shown in the enlarged view of FIG. 1, the spike pin 55 includes a tip pin portion 55a at the tip for piercing the empty resin container A, and an embedded portion 55b held in the press portion P behind the tip pin portion 55a. Further, it has a flange-like fixing and stabilizing portion 55c forming a part of the embedded portion 55b at the rear end, and a male screw 55s is formed in the embedded portion 55b.
[0016]
  Next, the lower roller unit 6 will be described. The lower roller unit 6 is of the same type as the upper roller unit 5 except that the spike pin 55 is not implanted, and is the same rubber first as the upper roller unit 5. The compression roller 61 </ b> A and the second compression roller 61 </ b> B are provided, and are supported by the rotation shafts 62 </ b> A and 62 </ b> B so as to be rotatable in a row with respect to the support frame 4. Further, the rotation shafts 62A and 62B are provided with gears 63A and 63B, respectively, and the drive gear 7a of the drive motor 7 and the gear 63A of the first compression roller 61A are engaged with each other, and the first compression roller 61A and the second compression roller 61B. The gears 63A and 63B are meshed with each other.
[0017]
  The distance between the lower roller unit 6 and the upper roller unit 5 is set to be relatively narrow, and thus the empty resin container A sent out by the upper roller unit 5 can be easily pulled in by the lower roller unit 6. It has become.
  Further, as shown in FIGS. 8 and 9, the first compression rollers 51A and 61A and the second compression rollers 51B and 61B in the upper roller unit 5 and the lower roller unit 6 have the same posture positions, respectively. When the press parts P of the upper roller unit 5 are close to each other, the press parts P of the lower roller unit 6 are also close to each other. A manual switch 8 of the drive motor 7 is provided on the front surface of the upper lid 21 of the storage box 2.
[0018]
  As shown in FIG. 6, the distance D1 between the receiving portions when the receiving portions C of the compression roller R face each other is 50 to 80% or less of the inter-axis distance D2 of the rotation shaft of the compression roller R. Is set. That is, by adopting a configuration in which the portion of the receiving portion C of the compression roller R is thus narrowed, the diameter of the compression roller R is reduced and the distance D2 between the axes of the compression rollers R is reduced, thereby reducing the size of the entire press unit 3. The empty resin container A can be accepted while achieving the above.
[0019]
  The empty resin container crusher 1 according to the present invention has a specific form as described above. Next, a method for manufacturing a compression roller for an empty resin container crusher according to the present invention will be described with reference to FIG. To do.
  First, the manufacturing apparatus will be briefly described. Reference numeral 80 denotes a molding die, and reference numeral 83 denotes a pin holder for holding the spike pin 55. The pin holder 83 has, for example, a cylindrical shape, and has a female screw portion 83a that is screwed into the male screw 55s of the spike pin 55 at the tip portion toward the inside of the mold 80, and the tip surface has a tapered taper. It is a surface. On the other hand, a flange 83b is formed on the rear end side. On the other hand, the molding die 80 is composed of two dies, and a pin holder support portion 81 for supporting the pin holder 83 is formed on the die mating surface.
[0020]
  Next, the manufacturing method using the said manufacturing apparatus is demonstrated.
  First, the tip end side of the spike pin 55 is screwed into the female screw portion 83 a of the pin holder 83, and the spike pin 55 is held by the pin holder 83. Incidentally, it is preferable to hold the spike pin 55 with as few screw threads as possible so as not to come off. The pin holder 83 holding the spike pin 55 is supported by the molding die 80, and the rotation shaft 52A integrated with the roller main body 54 (52A as an example in the drawing is the same as the rotation shaft 52B). Is also supported by the mold 80. Then, the divided molds 80 are combined, and NBR (acrylonitrile butadiene rubber) as a raw material of the roller main body 54 is then injected from the gate 82. At the time of this injection, the spike pin 55 is held by the pin holder 83 and therefore does not fall down.
[0021]
  Next, after the raw material is cross-linked to obtain a molded state, the molded product is removed from the mold 80, and the pin holder 83 is rotated and removed. Thereby, the compression roller for the empty resin container crusher according to the present invention, that is, the first compression roller 51A in the present embodiment is completed. Note that the periphery of the implanted spike pin 55 is somewhat recessed along the tapered surface at the tip of the pin holder 83.
  As described above, since the spike pin 55 is implanted simultaneously with the molding of the roller body 54, the manufacturing process is simple and fast. Further, compared to a case where only the roller main body 54 is first molded and then inserted by pin insertion later, the spike pin 55 is less wobbled and there is very little trouble that the spike pin 55 is removed.
[0022]
  Next, the operation mode of the empty resin container crusher will be described with reference to the drawings.
(1) Primary press (see FIGS. 8 (a) and 8 (b))
  The drive motor 7 is driven with the switch turned ON. The rotation of the drive gear 7a of the drive motor 7 is transmitted to the first compression rollers 51A and 61A of the upper roller unit 5 and the lower roller unit 6, and the rotation of the first compression rollers 51A and 61A is the second compression, respectively. It is transmitted to the rollers 51B and 61B by gears 53B and 63B.
  In the state where the empty resin container crusher 1 is driven as described above, the empty resin container A is charged from the upper charging cylinder 22 in a vertical posture. Then, the empty resin container A is sandwiched between the first compression roller 51 </ b> A and the second compression roller 51 </ b> B of the upper roller unit 5, and is crushed and is punched by the spike pin 55.
[0023]
(2) Secondary press (see FIGS. 9 (a) and 9 (b))
  The empty resin container A pressed and perforated by the upper roller unit 5 is received by the receiving portion C of the lower roller unit 6 and immediately sandwiched by the hook portion F, and the first compression roller 61A and the second It is drawn between the compression rollers 61B.
  The empty resin container A drawn between the first compression roller 61A and the second compression roller 61B is pressed by the press part P again. Since the perforated holes are made by the spike pins 55, the empty resin container A has low recoverability. Note that the low resilience of the empty resin container A due to the perforations made by the spike pins 55 is significant when the empty resin container A is put in a cover. Further, since an elastic material that can be deformed when the relative strength with the empty resin container A is weak is applied to the roller body 54, particularly, the restoring property of the empty resin container A is lowered, that is, the compressed state is maintained. Certainly planned. The empty resin container A after the secondary press is dropped as it is and is accommodated in the container body 20 of the accommodation box 2. Since the empty resin container A is crushed in the storage box 2, a very large number of empty resin containers A can be stored as compared with the case where the empty box is not crushed at all.
[0024]
  In addition to the empty resin container A, it goes without saying that compression is possible even when an empty can K is inserted as the object to be processed as shown in FIG. Incidentally, in the present invention, the name “empty resin container crusher” is used because it is possible to use even an empty resin container having a high technical difficulty in compression treatment as described above. The name “empty resin container crusher” is used in the present invention, and does not mean “crusher dedicated to empty resin container”. Specifically, as shown in FIGS. 10A, 10 </ b> B, 10 </ b> C, and 10 </ b> D, when the empty can K is inserted, crushing is started from the side body Kb of the empty can K, and the empty can K is pushed. Crushing is done. When the press part P of the compression roller R comes into contact with the rear end part Ka of the empty can K, if the empty can K is a thin and soft aluminum can, it is crushed flat as it is, but a hard steel can In this case, the rubber of the compression roller R is deformed and is not completely crushed into a flat plate shape as long as the can end portion Ka is curved.
[0025]
  Incidentally, the specific structure of the above-described empty resin container crusher 1 of the present embodiment is that of a prototype, and when this detailed numerical data is given, the drive motor 7 is a small silent motor with a torque of 500 kg / cm. It is what is used. The roller body 54 has a diameter L of 75 mm and an arc length N of the press portion of 53 mm (see FIG. 6). In addition, the length L of the arc of the press part can be variously changed in addition to 53 mm.
[0026]
[Other embodiments]
  Although the basic embodiment of the present invention is as described above, the following mechanism can be appropriately added or the basic structure can be modified when providing to the actual market.
  For example, as shown in FIG. 11, in consideration of safety when the empty resin container A or the like is charged, it is possible to provide the safety lid 10 so that a hand cannot be put into the charging port 22a. The safety lid 10 is configured such that the upper lid 10a and the lower lid 10b are opened and closed in conjunction with each other by a link or a chain, and when the upper lid 10a is opened as shown in FIG. When the lower lid 10b is closed and the upper lid 10a is closed as shown in FIG. 11B, the lower lid 10b is opened.
  In such a configuration, since the lower lid 10b is closed when the empty resin container A is inserted, it is safe because the hand cannot be put in the back, and when the upper lid 10a is closed, the lower lid 10b is opened. The empty resin container A is dropped onto the press unit 3.
[0027]
  Further, the drive of the drive motor 7 can be automatically started and stopped by detecting the empty resin container A dropping the charging cylinder 22. FIG. 12 shows an embodiment in which a closing detection switch 11 using a counter-transmission type infrared sensor or the like and a compression end detection switch 12 are provided. In this case, when the empty resin container A or the like is inserted, the insertion detection switch 11 detects it and transmits an ON signal to drive the drive motor 7. On the other hand, the compression end detection switch 12 detects the empty resin container A and transmits an ON signal first, and then transmits an OFF signal when the empty resin container A or the like falls and is no longer detected. Control is performed to stop driving of the drive motor 7 when a signal is transmitted. When the empty resin container A is stopped on the way, the switch is manually operated, for example, the compression roller R is reversed and taken out.
[0028]
  Considering the case where a non-compressible object such as a stone or an iron lump is inserted and the drive motor 7 is locked, when the surface temperature of the drive motor 7 during normal operation is exceeded, the thermal relay relays the drive motor 7 It is possible to stop the drive and automatically recover as the temperature drops.
[0029]
  Further, the interval between the upper roller unit 5 and the lower roller unit 6 may be adjustable. By making the interval between the upper roller unit 5 and the lower roller unit 6 adjustable, it is possible to crush a highly recoverable container such as a plastic bottle that is difficult to restore. It is also possible to detect and discriminate between transparent materials such as plastic bottles and non-transparent materials such as steel cans with an optical switch, etc., and automatically adjust the distance between the upper roller unit 5 and the lower roller unit 6. is there.
[0030]
  The spike pin 55 is provided only in the upper roller unit 5, but may be provided in the lower roller unit 6. Also, a plurality of spike pins 55 may be provided in one press portion P as shown in FIGS. 13 (a) and 13 (b), for example. Furthermore, the spike pin 55 can be applied in various forms as long as the empty resin container A can be perforated.The
[0031]
  The shape of the compression roller R can be implemented in various shapes in addition to those shown in the basic embodiment. For example, the compression roller R shown in FIG. F, the embodiment which provided the press part P and the receiving part C 3 each is shown.
[0032]
  14B shows an embodiment in which the shape of the hook portion F of the compression roller R is a shape that can be hooked to the left and right. According to this, for example, the hook portion F on one side is damaged. In that case, it can be used normally without replacement by turning it over.
[0033]
  Also, what is shown in FIG. 15 (a) is an embodiment in which a non-slip tooth Pa is provided for the press part P of the compression roller R, and what is shown in FIG. 15 (b) is a meshing tooth Pb. It is embodiment which provided. In the case of the compression roller R having the meshing tooth Pb, strictly speaking, the shape of the opposing compression roller R does not have a symmetric shape in a strict sense, but such a shape also looks symmetrical when viewed roughly. In the symmetrical shape of the present invention.
[0034]
  Further, the empty resin container crusher of the present invention is not necessarily limited to feeding the empty resin container A or the like vertically from the upper side to the lower side. For example, as shown in FIG. It is also possible to adopt an embodiment in which the is disposed obliquely and the empty resin container A is thrown obliquely. In this case, depending on the shape of the storage box, a larger storage space for the empty resin container A may be obtained.
[0035]
  Further, the empty resin container crusher of the present invention may be provided with a mechanism that not only crushes and collects the empty resin container A, but also returns coins or the like according to the recovered amount.
[0036]
  FIG. 17 is a cross-sectional view showing an embodiment in which the compression roller R is driven by the shaft-in motor 13, and the rotational force of the drive motor 71 is transmitted to an internal gear provided inside the outer cylinder 13A. Then, the outer cylinder 13A is rotated, and the compression roller fixedly installed on the outer cylinder 13A is rotated. The shaft-in motor 13 may be provided for each compression roller R, or the other compression rollers R may be driven by the compression roller R provided with one or two shaft-in motors 13. Good.
[0037]
【The invention's effect】
  A compression roller for a crusher for an empty resin container according to claim 1,2,Method for producing a compression roller for an empty resin container crusher according to claim 3, and claim4According to the described empty resin container crusher, since the spike pin 55 is implanted simultaneously with the molding of the roller main body 54, the manufacturing process is simple and fast. Compared with the case where the spike pin 55 is inserted and assembled later, the spike pin 55 is less wobbled and excellent in strength, and there are few troubles such that the spike pin 55 is detached. When an elastic material that can be deformed when the relative strength of the roller body 54 and the object to be processed is weak is applied, the empty resin container A is rarely restored after being crushed.
[0038]
  Also molding raw materialAsAfter being molded, an elastic material that can be deformed when the relative strength with the object is weak is appliedCaseAfter the empty resin container A is crushed, it is rarely restored.
[0039]
  Further, the spike pin 55 has a male screw 55 s formed on the peripheral surface of the embedded portion 55 b, while the pin holder 83 has a female screw portion 83 a, and the spike pin 55 is screwed to the pin holder 83. Therefore, the spike pin 55 is surely held at the time of molding, and does not fall or tilt due to the molding material to be injected. Further, since the male screw 55s is formed on the spike pin 55, the contact area between the spike pin 55 and the roller body 54 is large, and the spike pin 55 is firmly supported by the roller body 54.
