DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic container processing apparatus and a feeding roller, and more particularly, to a label and a mouth for reusing (recycling) collected plastic containers such as PET bottles. The present invention relates to a plastic container processing apparatus for separating and processing unnecessary materials such as the above, and a feed roller provided in the apparatus.

[0002]

2. Description of the Related Art Conventionally, in order to separate unnecessary materials such as labels and mouths in order to reuse plastic containers, unnecessary materials have been separated by manual operation or sorting in multiple steps after crushing. Was.

That is, a worker cuts off a label, a mouth, etc. from a collected plastic container by a cutter knife, a nipper, or the like, or separates the collected plastic container into chips by mechanically crushing the collected plastic container. To separate them.

[0004] In the latter case of mechanical sorting, sorting is first performed after coarse crushing is performed, and then chipped products are also sorted. After various sorting, plastic containers are recycled. Was something.

[0005] However, in the method in which the operator cuts and separates with a cutter knife or the like, the workability is extremely complicated because it is manually performed. In particular, when the collected plastic container is already compressed and deformed, it is extremely difficult to remove the mouth.

On the other hand, in the case of the above-mentioned mechanical sorting, a large number of steps are required, so that various processing apparatuses are required, equipment costs are increased, and a plurality of steps are repeated. This has led to a decrease in recovery.

Therefore, prior to the present invention, the invention of Japanese Patent Application No. 9-57763 was developed as a plastic container processing apparatus. In this plastic container processing apparatus, as shown in FIG. 9, a rotating rotor 19 'and a fixed blade are used.
When the plastic container is supplied to the processing means 14 'provided with the 59', the plastic container is compressed and deformed by the rotating blade 33 'and the fixed blade 59' of the rotating rotor 19 ', and while passing between the two. Stripping of the label, cutting of the mouth, and the like are performed, and unnecessary matter is removed.

In addition, since the plastic container processing apparatus is provided with the feed roller 49 'for feeding the plastic container to the processing means 14', the plastic container can be accurately processed by the processing means 14 '. Can be sent to Here, as a specific example of the feed roller 49 ', there is disclosed a configuration in which eight feed blades 50' are protrudingly provided on the outer periphery of the rotating shaft 51 'in parallel with the axial direction. .

[0009]

However, it is difficult for such a feeding roller 49 'to reliably catch a cylindrical plastic container. That is, when the plastic container is substantially parallel to the rotation axis of the feed roller 49 ', the rotating feed blade 50' is substantially tangent to the outer peripheral surface of the plastic container. Since the contact is made in the direction, the plastic container is merely rotated and cannot be held. Therefore, the feed roller 49 'intermittently generates an idling state in which only the outer peripheral surface of the plastic container is rubbed, and the plastic container cannot be efficiently fed to the processing means 14' side. there were.

In view of the above, the present invention has been made in view of the above-mentioned conventional problems, and can very easily separate unnecessary substances such as labels and mouths from a plastic container put into an apparatus. It is an object of the present invention to provide a plastic container processing apparatus and a feeding roller capable of reliably capturing a supplied plastic container in any state and feeding the same to processing means.

[0011]

Means for Solving the Problems In order to solve the above problems,

In the plastic container processing apparatus having the above-described configuration, the feeding roller is charged in a state where the plastic container is charged into the charging section 68 and the plastic container is stored in the housing 69.
By the rotation of 49, the feed roller 49 holds the plastic container and feeds it to the processing means 14, and thereafter,
The plastic container is processed in the processing means 14.

A feed roller 49 for feeding the plastic container to the processing means 14 is provided on the outer periphery of the rotating shaft 51, the outer edge of which is deviated from the intermediate portion 54 to the end portion 55 toward the rotating direction of the rotating shaft 51. When the feed roller 49 rotates, the plastic container is
It is sent while being moved to the center, following imitation. Moreover, even in the case where the plastic container has a relationship substantially parallel to the rotation axis of the feed roller 49, the holder 50 is gradually moved from the end 55 side to the intermediate portion 54 with respect to the plastic container.
Therefore, the rotation of the plastic container is not allowed, and the plastic container is held by the holder 50.

Therefore, regardless of the state of the cylindrical plastic container, the holder 50 captures the plastic container, holds the plastic container so as to prevent the rotation of the plastic container, and sends the plastic container to the processing means 14. .

Further, in the plastic container processing apparatus according to the present invention, the holding body 50 is a feeding blade 50 formed by bending a single band plate into a substantially mountain shape. It may be.

By adopting the above configuration, the holder 50
Since the action of sweeping out the plastic container occurs, the plastic container does not get caught or entangled in the holding body 50, and the holding means 50 holds the plastic container while sweeping the plastic container to the processing means. Send it.

Further, in the plastic container processing apparatus according to the present invention, the feed roller 49 is provided.
May be provided for primary compression of the plastic container.

By adopting the above configuration, when a plastic container which has not been compressed and deformed is placed in the loading section 68, the plastic container is primarily compressed by the feeding roller 49.
This primary compressed plastic container is easily processed by the processing means 14, and has the advantage that the separation process can be performed smoothly.

Further, in the plastic container processing apparatus according to the present invention, the feed roller 49 is provided.
It is preferable to adopt a configuration in which a perforation can be formed in the plastic container during feeding, whereby deformation of the plastic container can be prevented from being prevented by air inside the container body when the plastic container is compressed. When compressed, the volume of the plastic container can be accurately reduced. In other words, even in the case of a plastic container or the like having a cap at the mouth, the air inside the plastic container is accurately discharged from the perforation formed by the feed roller 49, so that the volume of the plastic container can be reduced. It has advantages.

Moreover, the side plates 52, 52 are circular disks having a radius substantially the same length as the distance from the rotation center of the drum 51a to the outer edge 50b of the feed blade 50, and therefore, the side plates 52, 52 are attached. In this case, the side plates 52, 52 come into contact with not only the end face of the drum 51a but also the end face of the end of the feeding blade 50.

As shown in FIG. 2, the feed roller of the present embodiment having the above-described structure has pivot portions 51b, 51b on both sides of the rotating shaft 51 of the feed roller 49. For convenience,
In FIG. 2, the left side is defined as a front and the right side is defined as a rear.

Further, the feed roller 49 is rotated by the feed electric motor 47, and more specifically, as shown in FIGS. 1 and 7, the feed electric motor 47 fixed to the swinging member 53. Sprocket 24a connected to one end of the rotary shaft
And a sprocket 24b fixed to one end of the rotation shaft 51 of the feed roller 49 are connected by a chain 27, and the feed roller 49 is rotated by driving the feed electric motor 47. I have. In addition, the rotation number of the electric motor 47 for feeding can be changed by inverter control.

The front end of the swinging member 53 is pivotally supported by a pivot 60 so that the pivoting member can be pivoted about the pivot 60.
53 is configured to swing, and the feed roller 49 is configured to move up and down. Here, the pivot 60 is a rotating shaft of the feed roller 49 when it is located on the front side of the processing means 14 and at the lowermost end.
It is fixed to the device frame 58 below 51.
Further, the swing member 53 is formed in a shape protruding upward at an intermediate portion so as not to come into contact with the processing means 14.

Therefore, in the supply means 15, the plastic container charged into the charging section 68 and stored in the hopper 69 moves to the fixing plate 57, and is pressed and deformed by the weight of the feed roller 49, while It is compressed and supplied to the processing means 14. Here, the fixing plate 57 is inclined downward toward the front facing the processing means 14 so that the plastic container can be mounted thereon. The fixing plate 57 is fixed to a device frame 58 fixed to the pedestal 70, and the fixing plate 57 is provided to be inclined downward toward the processing means 14.

As shown in FIGS. 1 to 3, the processing means 14 includes a separating device cover 18, a substantially cylindrical rotating rotor 19 rotatably mounted inside the cover 18, and a peripheral edge around the rotating rotor 19. The rotary blade 33 includes a rotary blade 33 attached so that the blade end 34 protrudes from the portion, and an opposing blade 59 fixed to a front end of a fixed plate 57 fixed to an apparatus frame 58.

Here, the rotating rotor 19 is rotated by an electric motor 23 for separation, and more specifically, a pulley connected to one end of a rotating shaft of the electric motor 23 for separation as shown in FIGS. 25a and a pulley 25b fixed to one end of the shaft 20 of the rotating rotor 19 are connected by a V-belt 26, and the rotating rotor 19 is rotated by driving the separation electric motor 23. The electric motor 23 for separation is also similar to the electric motor 47 for feeding,
The motor speed can be changed by inverter control. In addition, the rotation speeds of the separation electric motor 23 and the feeding electric motor 47 are set such that the peripheral speed of the blade end 34 of the rotary blade 33 is faster than the peripheral speed of the feeding blade 50.

As shown in FIG. 3, the rotating rotor 19 has two opposite peripheral edges cut out in a substantially L-shape to form a mounting notch 29 for mounting the rotary blade 33 thereon.
The mounting notch 29 is a mounting surface with which the side surface of the rotary blade 33 contacts.
30a and a rising surface 30b which rises at an acute angle from the mounting surface 30a, whereby the peripheral side of the rising surface 30b is formed to be inclined toward the blade end 34 with respect to the mounting surface 30a. The mounting surface 30a is provided with a screw hole 29a which can be screwed with a leg of a bolt 37 for fixing the rotary blade 33.

The rotary blade 33 housed in the mounting notch 29 so that the blade end 34 protrudes from the peripheral edge is a pressing member from the outside.
It is pressed by 31 toward the axis. The holding member 31
Is mounted so that the side surface portion comes into contact with the rising surface 30b of the mounting notch 29, and the peripheral portion is flush with the peripheral portion of the rotary rotor 19 when mounted in this manner, that is, the peripheral portion of the holding member 31. The portion and the peripheral edge of the rotating rotor 19 are formed so as to form an arc around the axis of the rotating rotor 19. The holding member 31 is formed with a concave portion that can be brought into contact with the head of the bolt 37 for fixing the rotary blade 33,
Further, a perforation hole through which the leg of the bolt 37 can be inserted is perforated from the recess. Here, the concave portion of the pressing member 31 has a sufficient depth that the head of the bolt 37 does not protrude from the surface of the pressing member 31.

Further, the rotary blade 33 is provided with a hole 35 through which the bolt 37 can be inserted, and the leg of the bolt 37 is inserted through the hole formed in the holding member 31 and the hole 35. The rotary blade 33 is screwed into the screw hole 29a of the rotary rotor 19, whereby the rotary blade 33 is sandwiched and fixed between the mounting surface 30a of the mounting notch 29 and the pressing member 31.

The hole 35 of the rotary blade 33 is provided with the bolt
The blade end of the rotary blade 33 with a width approximately the same as the outer diameter of the leg of 37
The rotary blade 33 is formed so as to be slidable toward the blade end 34 with respect to the bolt 37. By sliding in this manner, the rotary blade 33 can change the gap L between the rotary blade 33 and the opposing blade 59, but the gap L is preferably 3 mm or more, more preferably 5 mm or more. 25mm
Or less, and more preferably 15 mm or less.

Further, the rotary rotor 19 is cut out in an L-shape at the peripheral edge in the rotation direction from the protruding position of the blade end 34 of the rotary blade 33, so that unnecessary objects such as cut mouths or plastic containers are retracted. A possible relief 28 is formed. In addition, a discharge port 38 in which the device frame 58 is opened is formed below the rotating rotor 19.

Below the outlet 38, a container 72 is placed between the legs of the pedestal 70, as shown in FIG.

The plastic container processing apparatus of the present embodiment has the above-described configuration. Hereinafter, a method of using the plastic container processing apparatus will be described. In the following description, the peripheral speed of the blade end 34 of the rotary blade 33 is 15 m / s
Then, so that the peripheral speed of the feeding blade 50 becomes 0.5 m / s,
A case where the rotation speeds of the separation electric motor 23 and the feed electric motor 47 are set will be described.

First, the pre-processed (compressed and deformed to some extent) plastic container collected and conveyed by a collection vehicle or the like is charged into the charging section 68 and stored in the hopper 69.

Then, the plastic container is held by the feeding blades 50 of the rotating feeding roller 49, and is fed to the processing means 14 with the rotation of the feeding roller 49 in this state.

In addition, even if the pre-treatment is incompletely deformed due to imperfect pre-treatment and is a cylindrical plastic container, the feed blade 50 of the feed roller 49 has an outer edge extending from the intermediate portion 54 to the end portion. Since it is configured to be deviated in the rotation direction side of the rotating shaft 51 toward 55, the shape is easy to hold the cylindrical plastic container, and the plastic container is securely held and sent to the subsequent processing means 14. Is paid. That is, when the plastic container is positioned perpendicular to the rotation axis of the feed roller 49, the rotation of the feed roller 49 causes the plastic container to move toward the center while following the feed blade 50, The rotation of the plastic container is also stopped at the intermediate portion 54 of the feeding blade 50, so that the feeding blade 50 reliably holds the plastic container. Furthermore, when the plastic container is positioned substantially parallel to the rotation axis of the feed roller 49,
Since the holding body 50 gradually contacts the plastic container from the end portion 55 side to the intermediate portion 54, the plastic container is not allowed to rotate, and is reliably held by the feeding blade 50.

Therefore, regardless of the state of the plastic container, the feeding blade 50 surely catches the plastic container, stops the rotation of the plastic container, holds it, and sends it to the processing means 14.

The plastic container fed to the rotary rotor 19 by the feed roller 49 is
While being pressed and deformed by 19, the label is peeled off, and the mouth is cut off. Specifically, the label is scraped off by a rotating blade 33 sliding on the surface of the plastic container,
Further, it is considered that the opening formed harder than the other portions cannot be inserted through the gap between the rotary blade 33 and the opposing blade 59, and is cut.

The plastic container, the label, the mouth, etc., separated and discharged from the discharge port 38 in this way are stored in the container 72.

The plastic containers and the like housed in the container 72 are sorted into those to be conveyed to the next step for reuse and those unnecessarily. This sorting is performed by using any of mechanical sorting such as sieve sorting and wind sorting, or manual sorting, or a combination thereof.

Since the plastic container processing apparatus of the present embodiment is used as described above, it has the following advantages.

By adopting the hopper 69 having an open upper portion, a larger amount of plastic containers can be charged, and by charging the plastic container into the hopper 69, the rotating rotor 19 can be accurately rotated by the feeding roller 49. Has the advantage that it can be sent to

Further, since the fixing plate 57 is provided to be inclined downward toward the rotating rotor 19, the plastic container put into the charging section 68 can easily slide along the fixing plate 57 toward the rotating rotor 19. In addition, the plastic container on the fixing plate 57 can be easily fed to the rotary rotor 19 by the feeding roller 49, so that the separation process can be performed smoothly, and the lower fixing plate 57 can be conveyed by a belt conveyor or the like. It is not necessary to employ a device, and there is an advantage that the feed roller 49 can be reduced in size and weight.

The feed roller 49 is provided with a feed blade 50 on the outer periphery of the rotary shaft 51 such that the outer edge thereof is displaced from the intermediate portion 54 to the end portion 55 toward the rotation direction of the rotary shaft 51. Therefore, regardless of the state of the cylindrical plastic container, the feeding blades 50 can suppress the rotation of the plastic container and reliably hold the plastic container, and the intermittent idle state of the feeding roller 49 can be reduced. There is an advantage that the plastic container can be efficiently fed to the processing means 14 without any occurrence.

Further, the feed blade 50 of the feed roller 49 is
From the intermediate portion 54 to both end portions 55, the rotating shaft 51 is spirally formed.
Because the feed roller 49 rotates, a force is constantly applied to the plastic container caught by the feed blade 50 so that the plastic container is brought to the center of the feed roller 49 because the feed roller 49 rotates. Therefore, the plastic container can be fed to the substantially central portion of the processing means 14, and the processing efficiency of the plastic container can be improved.

The feed roller 49 is provided with a feed blade formed by bending a single band plate into a substantially mountain shape and using a drum 51 of a rotating shaft 51.
Since it is structurally simplified such that six pieces are protruded equally on the outer periphery of a, there is an advantage that it can be manufactured inexpensively and easily.

In addition, the feed roller 49 has a drum 51a.
And the side plate 52 that is in contact with and fixed to the end surface 55 of the feed blade 50, so that fine dust and debris do not easily enter the pivot shaft 51b of the rotating shaft 51, and the pivot shaft of the rotating shaft 51 It is possible to prevent the rotation of the apparatus 51b from becoming unrotatable due to biting of refuse, and to operate the apparatus smoothly and safely, and to reduce the number of maintenance operations.

Further, since the feeding roller 49 which can move up and down, that is, can retract with respect to the fixed plate 57 is employed, the fixed plate 57
Feed roller 49 with plastic container placed on top
Can be moved up and down to feed according to the amount and size of the plastic container charged, and the feeding roller
Since the plastic container can be fed while being pressed by its own weight of 49, the plastic container is not inadvertently escaped from the rotary blade 33 when the plastic container is processed, and the label or the like can be accurately separated. In particular, since the plastic container is primarily compressed by pressing the plastic container toward the fixing plate 57 side by the weight of the feed roller 49 in this way, the plastic container is accurately bitten between the rotary blade 33 and the opposing blade 59. Cheap.

Further, since the pivot 60 of the swinging member 53 to which the feed roller 49 is attached is located on the front side of the rotary roller 19, the feed roller 49 can be moved up and down by the swing of the swing member 53. The feeding of the plastic container can be approximated in the vertical direction, and the feeding roller 49 can be compactly mounted on the apparatus frame 58. Moreover, since the pivot shaft 60 of the swing member 53 is provided forward and below the rotation shaft 51 of the feed roller 49, a force acts forward on the feed roller 49 by the plastic container on the fixing plate 57. However, the swinging member 53 swings by this force, and the feeding roller 49 can be raised.

Further, since the feeding roller 49 has a sufficient weight to press and deform the plastic container placed on the fixing plate 57, the plastic container on the fixing plate 57 is primarily compressed by its own weight. Can be sent while
It is easy to bite between the rotary blade 33 and the opposing blade 59.

Further, since the feeding electric motor 47 for rotating the feeding roller 49 and the separating electric motor 23 for rotating the rotary rotor 19 are separately provided, the case where the separating device is stopped is provided. Even if there is, the feed roller 49 can be driven arbitrarily, whereby the feed roller 49 can be reversely rotated even if the plastic container is caught between the rotary blade 33 and the opposing blade 59. Having.

Further, the rotation speeds of the separating electric motor 23 and the feeding electric motor 47 are such that the peripheral speed of the blade end 34 of the rotary blade 33 is 15 m / s and the peripheral speed of the feeding blade 50 is 0.5 m. / S
In other words, since the feed roller 49 is set to feed the plastic container at a speed lower than the peripheral speed of the rotary blade 33, the speed of the plastic container passing through the gap between the rotary blade 33 and the opposing blade 59 is adjusted to some extent. As a result, the accuracy of separation of the label and the mouth by the rotary blade 33 can be improved. Moreover,
By changing the number of revolutions of the electric motor 23 for separation and the electric motor 47 for feeding, the peripheral speed ratio between the blade end 34 of the rotary blade 33 and the feeding roller 49 can be changed and set according to the work purpose. it can.

Further, the rotating rotor 19 is provided with a separated label and an escape portion 28 capable of retracting the mouth from the projecting position of the blade end 34 of the rotary blade 33 in the rotation direction. Separated label, mouth is the escape of rotating rotor 19
It does not escape to 28 and does not hinder the rotation of the rotating rotor 19.

Further, a substantially L-shaped mounting notch 29 is
The rising surface against the mounting surface 30a that abuts the side surface of 33
Since the peripheral side of 30b is formed so as to be inclined toward the blade end 34, centrifugal force acts on the rotary blade 33 and the holding member 31 attached to the mounting notch 29 when the rotary rotor 19 is rotated at high speed. However, a reaction force from the rising surface 30b acts on the holding member 31 against this centrifugal force, and the holding member 31
The rotary blade 33 can be accurately held by the 31 and the force acting on the bolt 37 as a fixing means can be reduced.

The hole 35 for mounting the rotary blade 33 is a blade end.
It is formed as a long hole extending to the 34 side, and the rotary blade 33 is
Is provided slidably on the blade end 34 side, so that the bolt 37 is loosened to release the holding by the holding member 31, and the rotary blade 33 is slid along the hole 35 to rotate the rotary blade.
33 The protruding length of the blade end 34 can be adjusted, and the opposite blade
The distance between 59 and rotary blade 33 can be changed as appropriate. In particular, since the hole 35 is formed with a width substantially equal to the outer diameter of the leg of the bolt 37, the rotary blade 33 does not shift in the lateral direction (the axial direction of the rotary rotor 19) during this sliding. .

Further, since the rotary blade 33 is held by being held by the pressing member 31, even if the rotary blade 33 is slid along the hole 35 toward the blade end 34, the pressing member 31 is not required. This has the advantage of receiving the reaction force of the centrifugal force from the rising surface 30b.

Further, the rotary rotor 19 can be easily manufactured by engraving the notch 29 for mounting and the escape portion 28 adjacent to each other, and the rotary blade 33 and the holding member 33 are bolted to the notch 29 for mounting. There is an advantage that the rotary blade 33 can be easily mounted on the rotary rotor 19 by mounting the rotary blade 19.

Further, as described above, the contents accommodated in the container 72 are separated into a plastic container, a label, a mouth, and the like, so that subsequent sorting operations such as manual sorting and sieving are easy. It has the advantage that it can be performed reliably. However, when the label etc. is stuck with an adhesive etc., there are cases where it is not completely separated from the plastic container.In such a case, the plastic container must be separately sorted by the operator. Becomes

Further, since the plastic container processing apparatus according to the above embodiment is a small plastic container to be processed, the apparatus itself can be relatively downsized. Therefore, the plastic container processing device can be placed on a truck bed to be movable, and the plastic container can be processed at each moving destination, for example, at a collecting place of the plastic container of each local government. .

<Other Embodiments> Although the first embodiment has the above-described structure and has the above-mentioned advantages, the plastic container processing apparatus according to the present invention is not limited thereto, and the scope of the present invention is intended. The design can be changed as appropriate.

That is, in the above embodiment, the feeding roller
49, a plurality of feed blades 50 formed by bending a single band plate along the axial length direction of the rotary shaft 51, and furthermore, the outer periphery of the feed blade 50 extends from the intermediate portion 54 to the end portion 55, and the rotary shaft 51 The feed roller 49 is not limited to this configuration.For example, the feed roller 49 may be configured such that a plurality of rod-shaped members are formed in the axial direction of the rotary shaft 51. A comb-shaped member is provided to project from the middle portion to the end of the rotating shaft 51 so as to be deviated toward the rotation direction of the rotating shaft 51, and the comb-shaped member is used as the holding member 50. A plurality of rows may be provided on the outer periphery of 51. The point is that, regardless of the state of the plastic container, if the feeding blade 50 (holding body) has the function of bringing the plastic container to the center and the function of stopping the rotation of the plastic container, the cylindrical plastic container can be used. Even a container can be securely held, which is the intent of the present invention.

The feed blade 50 of the feed roller 49
However, since the intermediate portion 54 is located at the intermediate portion of the drum 51a, the feeding blade 50 has a symmetrical shape, but is not limited to this, and the shape of the feeding blade 50 is substantially a U-shape. The intermediate portion 54 of the feeding blade 50 may be eccentric with respect to the intermediate portion of the drum 51a.

Further, the feed blade 50 of the feed roller 49
Is mounted so as to be orthogonal to the outer peripheral surface of the drum 51a at an arbitrary mounting position, but is not limited to this, and may be mounted at an acute angle so as to lie in the rotation direction of the feed roller 49. It may be mounted at an obtuse angle.
As described above, the rake angle can be changed by arbitrarily changing the mounting angle of the feed blade 50 with respect to the drum 51a, so that the feed capacity of the feed roller 49 can be changed and the size can be reduced. It can handle plastic containers of different materials.

Further, as shown in FIG. 6, a V-shaped notch 56 may be formed on the outer edge 50b of the feeding blade 50, and the outer edge 50b of the feeding blade 50 may have a desired shape. Projections with sharp tips may be provided at intervals.
With such a configuration, when the plastic container is held by the feeding roller 49 and fed, the notch 56 and the projection allow the air hole to be pierced in the plastic container, and the plastic container is easily compressed. That is, the feed roller 49 is provided so as to be capable of forming a perforation in the plastic container during feeding, so that when the plastic container is compressed, it is possible to prevent deformation of the plastic container from being hindered by air inside the plastic container. There is an advantage that the air inside the plastic container can be accurately discharged from the perforated hole, and the volume of the plastic container can be reduced. Also, when feeding the plastic container with the feed roller 49,
By forming the notch 56 and the projection on the feeding blade 50, there is also an advantage that the plastic container can be securely held.

Further, in the charging section 68 of the plastic container,
By providing a pushing means for pushing the plastic container inside the feeding section 68 into the feeding roller 49, for example, by providing a pushing arm or the like whose one end is swingable to the lower end portion of the feeding roller 49, the inside of the feeding section 68 is more securely provided. The plastic container can be supplied to the rotating rotor side by the feeding roller 49.

Further, the case where the hopper 69 is provided as the housing for housing the plastic container has been described. However, the present invention is not limited to this. For example, the case where the chute table having the fixing plate 57 extended is provided. By adopting this chute, the size of the apparatus can be reduced, and the chute can be folded to facilitate transportation of the apparatus.

Further, in the first embodiment, the electric motors 23 and 47 for rotating the feed roller 49 and the rotary rotor 19 make the number of rotations of the motor variable by inverter control. The invention is not limited to this, and a gearbox may be interposed between the axis of the feed roller 49 or the rotating rotor 19 and the axis of the motor to change the number of rotations of the motor, ,
An electric motor such as an electric motor with a variable speed variable transmission may be employed. In any case, the peripheral speed ratio between the blade end portion 34 of the rotary blade 33 and the feed roller 49 can be appropriately changed and set in accordance with the work purpose by appropriately adjusting the rotation speed of the electric motor. In addition, if a circuit for driving the electric motors 23 and 47 is incorporated in one sequence circuit and a configuration for synchronously controlling the electric motors 23 and 47 is adopted, the feeding and feeding of the blade end 34 of the rotary blade 33 to the rotary blade 33 can be performed more functionally. The peripheral speed ratio with the roller 49 can be changed and set.

The feeding roller 49 and the rotating rotor 19
As means for rotating the motor, a hydraulic motor may be employed instead of the electric motor. That is, a hydraulic motor driven by a feed hydraulic pump connected to an electric motor is connected to the feed roller 49 instead of the feed electric motor 47, while the rotary electric motor 19 is connected to the separation electric motor 23. Alternatively, a configuration may be employed in which a hydraulic motor driven by a separating hydraulic pump connected to the same electric motor is connected. In addition, if a flow control valve is provided in the separating hydraulic pump and the feeding hydraulic pump, the discharge amount can be changed, so that the two hydraulic motors have variable rotation speeds.

The rotary rotor 19 and the feed roller 49
Is rotated by a hydraulic motor, besides connecting the separating hydraulic pump and the feeding hydraulic pump coaxially to the same electric motor as described above, for example, connecting the feeding hydraulic pump to the shaft of the rotating rotor 19 It is also possible. in this way,
If a feed hydraulic pump is connected to the shaft of the rotating rotor 19 and a drive hydraulic pump for driving the feed roller 49 is driven,
Since the feeding roller 49 is configured to stop feeding when the rotation of the rotating rotor 19 is stopped, there is an advantage that the plastic container is not fed to the rotating rotor 19 while the rotating rotor 19 is stopped. If a configuration is adopted in which a feed hydraulic pump is connected to the shaft 20 of the rotating rotor 19 to drive a hydraulic motor for driving the feed roller 49, the feed roller 49 may be moved up and down. It has the advantage of being easy to manufacture.

In the first embodiment, an example in which the opposed blade 59 is provided at a position having a fixed gap L with the rotation trajectory of the rotary blade 33, which is fixed to the front end of the fixed plate 57, will be described. However, the present invention is not limited to this. That is, the rotation locus of the rotary blade 33 and the constant gap L
It is also possible to configure the opposing blade 59 with a low-speed rotary blade provided so as to rotate at a lower speed than the rotary blade 33 at a position having. Such a low-speed rotary blade is disposed on the outer periphery of a low-speed rotary rotor whose rotation speed is lower than that of the rotary rotor 19, and is rotated in a direction opposite to the rotary blade 33. Note that the axis of the low-speed rotating rotor 91 is not eccentric, and the low-speed rotating blade 59 may be provided so as to always maintain a predetermined gap with the rotation trajectory of the rotating blade 33. With a slight eccentricity, the rotation locus of the rotary blade 33 and the rotation locus of the rotary blade 33 may be varied within a certain range L by rotating the low-speed rotary blade 59.

Further, the opposed blade 59 is not limited to the one fixed to the front end of the fixed plate 57, and may be any member as long as it separates unnecessary substances such as labels from the plastic container by the rotary blade 33. For example, the end of the fixing plate 57 can be directly used as the opposing blade 59.

In the present invention, the means for attaching the rotary blade 33 is not limited to that of the first embodiment, and a hole 35 through which the fixing means 37 can be inserted into the rotary blade 33 is formed. In this case, the fixing means 37 is not limited to the one formed with a width substantially the same as the outer diameter of the leg part. Further, in the first embodiment described above, the hole 35 is formed as a long hole.
It is also possible to form a hole extending to the other end of 34, which has an advantage that detachment of the rotary blade 33 can be performed more easily.

Further, even when the rotary blade 33 is mounted on the substantially L-shaped mounting notch 29 in which the peripheral side of the rising surface 30b is inclined toward the blade end 34 with respect to the mounting surface 30a, As in the embodiment, the mounting notch 29 is not limited to the mounting surface 30a in which the rising surface 30b is formed to rise at an acute angle with respect to the mounting surface 30a, but is curved toward the blade end 34 toward the peripheral edge of the rising surface 30b. Even when the peripheral edge of the rising surface 30b is inclined toward the blade end 34, there is an advantage that the rotary blade 33 can be properly held by the reaction force against the centrifugal force as described above.

In the first embodiment, the case where the processing means 14 and the supply means 15 are fixed on the pedestal 70 has been described. However, the plastic container processing apparatus according to the present invention is not limited to this. For example, as shown in FIG. 8, it can be mounted on a vehicle body D having a storage box 1 and a tailgate 12 for opening and closing the rear opening of the storage box 1. Further, if the separation roller is compactly mounted on the apparatus main body as in the first embodiment to reduce the size and weight of the separation apparatus, the separation roller can be easily mounted on the tailgate 12 of the vehicle body D as shown in FIG. It has the advantage of being able to.

In the first embodiment described above, the feeding roller 49 is provided so as to be retractable by the plastic container of the loading section 68. However, the feeding roller 49 does not move up and down. It may not be provided so as to be able to be evacuated by the 68 plastic containers.

As described above, in the plastic container processing apparatus according to the present invention, the feed roller for feeding the plastic container to the processing means is provided with the outer edge extending from the intermediate portion to the end portion in the direction of rotation of the rotating shaft. Since the holding body is provided so as to be deviated to any position, the holding body can reliably catch the plastic container regardless of the state of the cylindrical plastic container, and the rotation of the plastic container is stopped. The plastic container can be held securely, and the feed roller does not intermittently run idle. Therefore, the plastic container can be efficiently fed to the processing means.

Further, in the plastic container processing apparatus according to claim 2 of the present invention, the holding member is formed of a feeding blade formed by bending a single band plate into a substantially mountain shape, and the holding member is formed of a plastic container. Since the feeding is carried out to the processing means in a sweeping manner while being held, it is possible to preferably prevent the plastic container from being caught or entangled in the holding body, so that the feeding roller may not be able to rotate. Not
The practical effect is remarkable in that the apparatus can be operated stably and the production can be performed at low cost.
