Description

[Technical field]

[0001] The present invention relates to a scrap crushing and transporting device, and more specifically to a scrap crushing and transporting device that crushes and transports scrap rubber material such as scrap (waste) of rubber material left over after making footwear soles, etc., so that it can be recycled. [Background technology]

[0002] In general, the sole of footwear protects the sole of the foot, increases friction with the ground to improve walking comfort, and reduces shocks applied to the sole of the foot when walking. The sole of such footwear is composed of an insole, a midsole made of rubber, foamed resin, or sponge material with excellent shock-absorbing properties to elastically distribute and support the weight of the human body when walking, and an outsole made of rubber material attached to the bottom of the midsole to provide friction when walking. As an example, Korean Patent Registration No. 10-1760577 (2017.07.17.) discloses a method for manufacturing an insole for footwear.

[0003] Meanwhile, in the process of manufacturing footwear, a woven fabric is layered on the top surface of a flat foam body having a roughly rectangular shape to form a plate-like laminate, and then a laminate for an insole having the shape of a sole of a foot is cut off from the plate-like laminate. When the laminate for an insole is cut off from the plate-like laminate in this way, insole scraps (insole waste) with openings formed in the shape of a sole of a foot are left behind, and a very large amount of such insole scraps is generated in the insole manufacturing process. At present, in spite of the fact that a very large amount of insole scraps is generated, they are simply disposed of, which not only wastes resources but also causes environmental destruction. In addition, there is a problem that dust generated in the crushing process accumulates, causing breakdowns in the crushing and conveying devices. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] The terms used in this specification will be briefly explained, and the present invention will be described in detail.

Therefore, the terms used in the present invention should be defined not simply as names of terms, but based on the meanings of the terms and the overall content of the present invention.

[0019] Throughout this specification, when a part is described as "comprising" a certain component, this does not mean that it excludes other components, and means that it may further include other components, unless otherwise specified.

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. However, the present invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0021] The specific matters including the problems to be solved by the present invention, the means for solving the problems, and the effects of the invention are included in the following embodiments and drawings. The advantages and features of the present invention, as well as the methods for achieving them, will become more apparent by referring to the following embodiments in conjunction with the accompanying drawings.

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] A scrap crushing and transporting device according to a preferred embodiment of the present invention includes a coarse crusher 10 that crushes scrap, a fine crusher 11 that re-crushes the scrap crushed in the coarse crusher 10, and a transporter 100 that stores the scrap or transports it to the coarse crusher 10 or the fine crusher 11.

[0024] First, the conveyor 100 is provided. The conveyor 100 serves to suck in and store the scrap pulverized in the coarse pulverizer 10 or the fine pulverizer 11 via a pipe 34 described below, and to discharge the stored scrap as necessary.

[0025] Referring to FIG. 1, the conveyor 100 includes a chamber 31 that forms a space in which the scrap can be stored, a pump unit 29 that is disposed on one side of the chamber 31 and that changes the air pressure within the chamber 31, and an inlet 35 that is connected to the chamber 31 and that allows the scrap to be conveyed into the chamber 31.

[0026] More specifically, the chamber 31 is cylindrical and forms a space inside in which the scrap can be stored. At this time, the inlet 35 is provided on a side surface of the chamber 31, and the inlet 35 can be connected to the coarse crusher 10 or the fine crusher 11 by piping, which will be described later. That is, the scrap crushed by the coarse crusher 10 or the fine crusher 11 can flow into the chamber 31 through the inlet 35.

[0027] Further, the pump unit 29 is provided at the top of the chamber 31 and is disposed in communication with the interior of the chamber 31, and the pump unit 29 varies the air pressure within the chamber 31 by discharging air within the chamber 31 to the outside or supplying air from the outside into the chamber 31. That is, when the scrap is transported into the chamber 31, the pump unit 29 creates a negative pressure overall within the chamber 31, or high-pressure air is instantly ejected to the outside via the inside of the chamber 31, creating a negative pressure at the upper end of the interior of the chamber 31, and the scrap is sucked into the chamber 31 through the inlet 35 connected to a pipe to be described later.

[0028] Here, a compressed air exhaust port may be provided at a position symmetrical to the pump unit 29 at the top of the chamber 31. That is, as shown in FIG. 1, the pump unit 29 is disposed at the upper left end of the chamber 31, and the compressed air exhaust port is disposed at the upper right end of the chamber 31, and can be opened and closed by a separate valve. For this reason, when it is necessary to suck the scrap, the pump unit 29 injects compressed air, and the compressed air is instantly ejected to the outside through the exhaust port after passing through the inside of the chamber 31. In other words, based on the same principle as that of a sprayer (Bernoulli's principle), the scrap can be sucked into the chamber 31 through the inlet 35 due to an instantaneous pressure change as the compressed air is quickly ejected to the outside through the inside of the chamber 31. In addition, when the inlet 35 or a pipe described later is blocked by the scrap, the pump unit 29 may eject compressed air at high speed and eject it to the outside through the inside of the chamber 31, thereby transporting the scrap. As an example, the pump section 29 may include a first pump that ejects air inside the chamber 31 to the outside, and a second pump that supplies compressed air that passes through the inside of the chamber 31 in the opposite direction to the first pump and is ejected to the outside.

[0029] Next, the conveyor 100 further includes a discharge port 102 that is connected to the chamber 31 to allow the scrap transported into the chamber 31 to be discharged to the outside, and a damper 30 that opens and closes the discharge port 102.

[0030] More specifically, the conveyor 100 further includes a tapered housing 104 formed under the chamber 31 and having a cross-sectional area that gradually narrows as it progresses downward, and the housing 104 is coupled to the lower part of the chamber 31. At this time, the exhaust port 102 is provided at the lower end of the housing 104. Also, the exhaust port 102 is opened and closed by the damper 30, and for example, the damper 30 opens and closes the exhaust port 102 using the operation of an actuator such as a cylinder. Here, the damper 30 may refer to a manual or automatic air volume control device disposed in a duct to control the direction, speed, and amount of air.

[0031] The conveyor 100 further includes a communication part 105 formed in a lower part of the chamber 31, in a shape that encloses the housing 104 and has the same diameter as the chamber 31. The communication part 105 communicates with a space or device to which the scrap stored in the chamber 31 is to be supplied when the scrap is discharged downward. As an example, an upper part of the communication part 105 communicates with the chamber 31, and a lower part of the communication part 105 communicates with the pulverizer 11. The communication part 105 is a cylindrical tube and can be connected to the chamber 31 by a connecting part 106-1. The communication parts 105 are plural and can be connected to each other by a connecting part 106-2, so that the length can be further increased.

[0032] As a result, when the scrap is sucked into the chamber 31, a negative pressure is created inside the chamber 31 by the pump unit 29 with the discharge port 102 closed by the damper 30, and when the scrap is discharged, the discharge port 102 is opened by the damper 30, so that the scrap is discharged downward through the discharge port 102. The discharged scrap is transported along the communication part 105.

[0033] Next, the conveyor 100 further includes a filter unit 101 disposed inside the conveyor 100 and collecting dust inside the conveyor 100. The filter unit 101 serves to electrostatically collect fine scrap particles or dust generated from the scrap conveyed into the chamber 31 using, for example, an electrostatic dust collection filter, and prevents dust from accumulating on the pump unit 29 or a valve, thereby preventing the performance of the pump unit 29 from being reduced. For example, a plurality of filter units 101 may be disposed under the pump unit 29, i.e., at the upper left end of the chamber 31 and the corresponding upper right end of the chamber 31, respectively. Therefore, the plurality of filter units 101 serves to prevent dust from accumulating on the pump unit 29 and the exhaust port.

[0034] When discharging the scrap, the pump unit 29 injects air downward within the chamber 31 with the discharge port 102 open by the damper 30, thereby cleaning the filter unit 101. In other words, after the scrap is discharged downward with the discharge port 102 open, the pump unit 29 injects air in a direction toward the filter unit 101 to remove the scrap dust and the like collected in the filter unit 101. Therefore, the clumped scrap dust removed from the filter unit 101 by the pump unit 29 is discharged downward through the discharge port 102.

[0035] The conveyor 100 further includes a vent port 103 that allows at least a part of the air injected from the pump unit 29 to flow to the outside when discharging the scrap, and the vent port 103 includes a vent filter 103-1 that is disposed in a shape that covers the inside of the vent port 103 and filters the air flowing to the outside. At this time, one side of the vent port 103 is formed to communicate with one side of the communication part 105 and the inside of the communication part 105, and the other side of the vent port 103 is communicated with the outside. Therefore, the vent port 103 serves to prevent the air pressure inside the chamber 31 and the communication part 105 from increasing due to the air injected from the pump unit 29. In this process, the scrap dust in the air flowing to the outside through the vent port 103 is filtered by the vent filter 103-1.

[0036] As a result, the pump unit 29 transports the pulverized scrap into the chamber 31, and when the scrap stored in the chamber 31 is discharged downward, air is sprayed onto the filter unit 101, so that the scrap particles formed in a lump form in the filter unit 101 are discharged downward. In this manner, the vent unit 103 is provided to prevent the pressure from increasing due to the air sprayed from the pump unit 29 when the filter unit 101 is cleaned, and dust in the air discharged to the outside through the vent unit 103 is filtered by the vent filter 103-1.

[0037] On the other hand, the conveyor 100 can be applied to a first conveyor section 19, a second conveyor section 22, a third conveyor section 25, and a fourth conveyor section 28, which will be described later.

[0038] Hereinafter, a multi-stage scrap crushing and transporting device using a plurality of transporters 100 will be described in detail with reference to the accompanying drawings. Fig. 2 is a perspective view showing a coarse crusher of the scrap crushing and transporting device according to one embodiment of the present invention, Figs. 3 to 5 are front, plan and side views showing the coarse crusher of the scrap crushing and transporting device according to one embodiment of the present invention, and Fig. 6 is an enlarged view showing the coarse crusher of the scrap crushing and transporting device according to one embodiment of the present invention.

[0039] As shown in Figures 2 to 6, the coarse crusher 10 is a device that primarily crushes scrap 100 such as rubber material. More specifically, the coarse crusher 10 includes a coarse crushing input section 14 having a rotating table 13 and a number of hangers 12 on which scrap can be hung, a coarse crushing input hopper section 16 that is disposed in front of the coarse crushing input section 14 and feeds the scrap that falls from the hangers 12 into the primary coarse crushing section 15, a primary coarse crushing section 15 that is disposed below the coarse crushing input hopper section 16 and crushes the scrap fed from the coarse crushing input hopper section 16 using a rotating first cutter 17 for coarse crushing, and a first conveying section 19 that is disposed on one side of the primary coarse crushing section 15 and is connected between the discharge hopper 18a side of the primary coarse crushing section 15 and the packaging section 27a to convey the scrap particles discharged from the primary coarse crushing section 15 to the packaging section 27a. The hangers 12 of the coarse crushing feeding section 14 are arranged at a constant pitch while following the peripheral edge of the table 13, and have a length extending to the entrance of the coarse crushing feeding hopper section 16, so that scrap can be fed in when each hanger 12 is positioned above the entrance of the coarse crushing feeding hopper section 16 by the rotating table 13.

[0040] The coarse crushing and feeding section 14 is a means for hanging and arranging scrap before it is fed in, and is equipped with a circular table 13 that can be rotated by a driving section (not shown) such as a motor while maintaining a vertical position, and a number of hangers 12 on which the scrap can be hung are arranged in front of such table 13.

[0041] Here, the hangers 12 are in the form of a straight bar, and consist of a number of them arranged at a constant pitch while following the peripheral edge of the table 13; for example, eight of them are arranged at intervals of approximately 45° while following the circumferential direction of the table. One end of such a hanger 13 is fixed onto the table 13, while the other end has a length that extends horizontally to just above the entrance of the coarse crushing input hopper section 16.

[0042] As a result, when one of the hangers 13 is positioned at the entrance of the coarse crushing input hopper section 16 due to the rotation of the table 13, a large number of scraps hung on the hangers 13 can be pushed forward and removed, either automatically or manually by the operator, and the scraps will fall into the entrance of the coarse crushing input hopper section 16 and can be fed into it.

[0043] The coarse crushing input hopper section 16 has a box-like structure having a rear inlet through which scrap is input and a lower outlet through which the scrap is discharged to the primary coarse crushing section 15. It is positioned in front of the coarse crushing input section 14 and serves to supply the scrap dropping from the hangers 12 to the primary coarse crushing section 15.

[0044] Such a coarse crushing input hopper section 16 is disposed in such a manner that its lower end is placed on and supported by the upper end of the primary coarse crushing section 15, that is, the upper end into which the scrap flows.

[0045] For this purpose, the front side of the lower end of the coarse crushing input hopper section 16 is supported by a hinge device 32 in a rotatable structure on the front side of the upper end of the primary coarse crushing section 15, and at the same time, the front side of the lower end of the coarse crushing input hopper section 16 is supported by a toggle clamp 33 in a structure that can be opened and closed on the rear side of the upper end of the primary coarse crushing section 15.

[0046] The lower end of the coarse crushing input hopper section 16 arranged in this manner is connected to the upper end of the primary coarse crushing section 15 in a shape that fits snugly with the upper end of the primary coarse crushing section 15, thereby enabling scrap that has entered the interior of the coarse crushing input hopper section 16 to be sent directly into the interior of the coarse crushing input hopper section 16.

[0047] By locking the toggle clamp 31, the coarse crushing input hopper section 16 can be pushed forward, thereby exposing the upper end of the primary coarse crushing section 15 to the outside. This makes it possible to effectively manage the primary coarse crushing section 15, for example, by performing maintenance, inspection, cleaning, etc. on the inside of the primary coarse crushing section 15 without dismantling or dismantling the entire apparatus.

[0048] The primary coarse crushing section 15 is essentially a means for crushing scrap, and is disposed in front of the coarse crushing input section 14 and below the coarse crushing input hopper section 16 while being supported by a frame structure.

[0049] The primary coarse crushing section 15 includes a first cutter 17 for coarse crushing that is rotated by a drive section 38 such as a motor drive means or a belt transmission means.

[0050] As a result, when scrap is fed from the upper coarse crushing input hopper section 16 to the lower primary coarse crushing section 15 during operation of the primary coarse crushing section 15, the scrap is cut and finely crushed by the rotating first coarse crushing cutter 17, and the scrap particles thus crushed pass through the discharge hopper 18a at the lower end of the primary coarse crushing section 15, before being sent to the first conveying section 19 and packaged in the packaging section 27a.

[0051] The first conveying section 19 serves to convey the scrap particles that have been crushed in the primary coarse crushing section 15 to the packaging section 27a by using a method such as vacuum pressure or suction pressure.

[0052] For this purpose, the first conveying section 19 is disposed on one side of the primary coarse crushing section 15, and the suction side of the first conveying section 19 thus disposed is connected to the discharge hopper 18a side in the primary coarse crushing section 15 by piping 34, while the discharge side is vertically connected to the lower packaging section 27a, for example, the packaging section 27a side equipped with bags (not shown) into which scrap particles can be placed.

[0053] The first conveying section 19 includes a pump section 29, and the pump section 29 exerts a suction force to suck in and convey the screen particles.

[0054] Here, the pump section 29 is disposed in a structure supported on the upper end of the chamber 31, and the suction side of the pump section 29 is capable of communicating with the inside of the chamber 31, and a mesh screen or the like is interposed between the suction side and the inside of the chamber, making it possible to prevent scrap particles from flowing into the pump side.

[0055] The first conveying section 19 also includes a chamber 31 capable of storing a certain amount of scrap particles that are conveyed and flow in by a suction method.

[0056] A scrap particle inlet 35 is formed on the side of the chamber 21, and a pipe 34 extending from the discharge hopper 18a of the primary coarse crushing section 15 can be connected to the scrap particle inlet 35 thus formed.

[0057] The first transport section 19 is provided with a damper 30 that can be opened and closed. In this case, the damper 30 can be disposed on the discharge side of the lower end of a chamber 31.

[0058] Here, it is preferable that the damper 30 is opened and closed by the operation of an actuator such as a cylinder.

[0059] As a result, when the damper 30 is closed and the pump section 29 is operated, the suction force causes the scrap particles in the discharge hopper 18a of the primary coarse crushing section 15 to be transported along the piping 34 and accumulate inside the chamber 31 via the scrap particle inlet 35. When the damper 30 is opened, the scrap particles thus accumulated fall to the bottom and can be placed in bags or the like in the packaging section 27a for packaging.

[0060] FIG. 7 is an oblique view showing a fine pulverizer of a scrap crushing and transporting device according to one embodiment of the present invention, FIG. 8 to FIG. 10 are a front view, a plan view and a side view showing a fine pulverizer of a scrap crushing and transporting device according to one embodiment of the present invention, and FIG. 11 to FIG. 13 are enlarged views showing a fine pulverizer of a scrap crushing and transporting device according to one embodiment of the present invention.

[0061] As shown in Figs. 7 to 13, the fine pulverizer 11 is a device for finely pulverizing scrap particles delivered in a roughly pulverized state by using two pulverizing processes. More specifically, the fine pulverizer 11 is sequentially arranged on a frame structure, and includes a fine pulverizing input section 21 for storing scrap particles provided from a first conveying section 19 and then inputting the scrap particles to a secondary fine pulverizing section 20, a second conveying section 22 connected between the fine pulverizing input section 21 and the secondary fine pulverizing section 20 for conveying and inputting the scrap particles in the fine pulverizing input section 21 to the secondary fine pulverizing section 20, and a second conveying section 22 for conveying the scrap particles in the fine pulverizing input section 21 to the secondary fine pulverizing section 20 by using a second cutter 23 for fine pulverization that rotates while being disposed below the second conveying section 22. the scrap particles in the discharge hopper 18b to the tertiary fine crushing section 24 and input to the tertiary fine crushing section 24; a third conveying section 25 connected between the discharge hopper 18b of the secondary fine crushing section 20 and the tertiary fine crushing section 24 for conveying and inputting the scrap particles in the discharge hopper 18b to the tertiary fine crushing section 24; the tertiary fine crushing section 24, which is disposed below the third conveying section 25, and which uses a rotating third cutter 26 for fine crushing to crush the scrap particles input from the third conveying section 25; and a fourth conveying section 28 connected between the discharge hopper 18c of the tertiary fine crushing section 24 and a packaging section 27b for conveying and inputting the scrap particles in the discharge hopper 18c to the packaging section 27.

[0062] The fine pulverizing input section 21 is a kind of storage hopper, and serves to temporarily store the wrapped scrap particles provided in the wrapping section 27a on the coarse pulverizer 10 side, and then input the wrapped scrap particles to the secondary fine pulverizing section 20 side.

[0063] Here, the method of communication of the scrap particles between the packaging section 27a on the coarse crusher 10 side and the fine crushing input section 21 on the fine crusher 11 side, i.e., the method of transporting the bags containing the scrap particles, can be a method in which the operator transports them himself or a method in which a conveyor is used for transporting them.

[0064] The second conveying section 22 is connected between the fine pulverizing input section 21 and the secondary fine pulverizing section 20, and serves to convey and input the scrap particles in the fine pulverizing input section 21 to the secondary fine pulverizing section 20 using a method such as vacuum pressure or suction pressure.

[0065] For this purpose, the second conveying section 22 is supported on the upper end of the secondary fine grinding section 20 and is arranged in a structure in which it is connected to the upper end of the secondary fine grinding section 20. The suction side of the second conveying section 22 arranged in this manner is connected to the discharge side of the fine grinding input section 21 by piping 34, and at the same time, the discharge side is connected to the inlet side of the upper end of the lower secondary fine grinding section 20.

[0066] The second conveying section 22 includes a pump section 29, and the pump section 29 exerts a suction force to suck in and convey the screen particles.

[0067] Here, the pump section 29 is disposed in a structure supported on the upper end of the chamber 31, and the suction side of the pump section 29 is capable of communicating with the inside of the chamber 31, and a mesh screen or the like is interposed between the suction side and the inside of the chamber, making it possible to prevent scrap particles from flowing into the pump side.

[0068] The second conveying section 22 also includes a chamber 31 capable of storing a certain amount of scrap particles that are conveyed and flowed in by a suction method.

[0069] A scrap particle inlet 35 is formed on the side of the chamber 31, and a pipe 34 extending from the input portion 21 for fine grinding can be connected to the scrap particle inlet 35 thus formed.

[0070] The second transport section 22 is provided with a damper 30 that can be opened and closed, and the damper 30 in this case can be disposed on the discharge side of the lower end of a chamber 31.

[0071] Here, it is preferable that the damper 30 is opened and closed by the operation of an actuator such as a cylinder.

[0072] As a result, when the pump section 29 is operated with the damper 30 closed, the suction force causes the scrap particles in the fine grinding input section 21 to be transported along the piping 34 and accumulate inside the chamber 31 via the scrap particle inlet 35. When the damper 30 is opened, the scrap particles thus accumulated fall to the bottom and can be fed into the secondary fine grinding section 20.

[0073] The secondary pulverizing section 20 is disposed below the second conveying section 22 and serves to pulverize the scrap particles fed from the second conveying section 22 using a rotating second cutter 23 for pulverization.

[0074] For this purpose, a shaft 37 is disposed inside the secondary fine grinding section 20, the shaft 37 having at one end a pulley 36 to which power is transmitted from a motor (not shown) and at the same time both ends supported by bearings 54. A number of second cutters 23 for fine grinding are connected to the shaft 37 so as to be aligned along the axis while forming a coaxial structure.

[0075] Here, the rotating second cutter 23 for fine grinding is disposed inside the secondary fine grinding section 20, and is arranged next to the second cutter 23 for fine grinding with a certain gap between them, thereby enabling the scrap particles to be crushed by strongly striking them together with a fixed cutter (not shown) that forms a pair with the second cutter 23 for fine grinding.

[0076] In a preferred embodiment, the secondary fine grinding section 20 is equipped with a cooling device having a circulation structure with a chiller (cooling water circulating device) (not shown), which makes it possible to effectively cool the heat generated when the scrap particles are ground by the second cutter 23 for fine grinding.

[0077] The second cutter 23 for fine grinding in the secondary fine grinding section 20 is made of a block-shaped cutter, and the second cutter 23 for fine grinding in this case has a relatively wider cutter width than the third cutter 26 for fine grinding in the tertiary fine grinding section 24, and moreover the number of cutters is relatively smaller, so that it is possible to crush the scrap particles into larger pieces than the third cutter 26 for fine grinding, but to crush the scrap particles into smaller pieces than the first cutter 17 for coarse grinding in the primary coarse grinding section 15 on the coarse grinder 10 side.

[0078] That is, the second cutter 23 for fine grinding of the secondary fine grinding section 20 consists of a block-shaped cutter, and the third cutter 26 for fine grinding of the tertiary fine grinding section 24 consists of a knife-shaped cutter, and the third cutter 26 for fine grinding of the tertiary fine grinding section 24 has a relatively narrower cutter width than the second cutter 23 for fine grinding of the secondary fine grinding section 20, and also has a relatively greater number of cutters, so that the third cutter 26 for fine grinding can grind scrap particles even finer than the second cutter 23 for fine grinding.

[0079] As a result, when scrap particles fed from the second conveying section 22 enter the interior of the secondary fine grinding section 20 during operation of the secondary fine grinding section 20, the scrap particles are finely ground as they pass between the rotating second cutter 23 for fine grinding and the fixed cutter, and then drop into the lower discharge hopper 18b and accumulate there.

[0080] The third conveying section 25 is connected between the discharge hopper 18b of the second fine pulverizing section 20 and the third fine pulverizing section 24, and serves to convey and input the scrap particles in the discharge hopper 18b to the third fine pulverizing section 24 by using a method such as vacuum pressure or suction pressure.

[0081] For this purpose, the third conveying section 25 is supported on the upper end of the tertiary fine grinding section 24 and is arranged in a structure in which it is connected to the upper end of the tertiary fine grinding section 24. The suction side of the third conveying section 25 thus arranged is connected to the discharge hopper 18b side of the secondary fine grinding section 20 by piping 34, and at the same time, the discharge side is connected to the inlet side of the upper end of the lower tertiary fine grinding section 24.

[0082] The third conveying section 25 includes a pump section 29, and the pump section 29 exerts a suction force to suck in and convey the screen particles.

[0083] Here, the pump section 29 is disposed in a structure supported on the upper end of the chamber 31, and the suction side of the pump section 29 is capable of communicating with the inside of the chamber 31, and a mesh screen or the like is interposed between the suction side and the inside of the chamber, making it possible to prevent scrap particles from flowing into the pump side.

[0084] The third conveying section 25 also includes a chamber 31 capable of storing a certain amount of scrap particles that are conveyed and flowed in by a suction method.

[0085] A scrap particle inlet 35 is formed on the side of the chamber 21, and a pipe 34 extending from the discharge hopper 18b of the secondary pulverizing section 20 can be connected to the scrap particle inlet 35 thus formed.

[0086] The third transport section 25 is provided with a damper 30 that can be opened and closed. In this case, the damper 30 can be disposed on the discharge side of the lower end of the chamber 31.

[0087] Here, it is preferable that the damper 30 is opened and closed by the operation of an actuator such as a cylinder.

[0088] As a result, when the pump section 29 is operated with the damper 30 closed, the suction force causes the scrap particles in the fine grinding input section 21 to be transported along the piping 34 and accumulate inside the chamber 31 via the scrap particle inlet 35. When the damper 30 is opened, the scrap particles thus accumulated fall to the bottom and can be fed into the tertiary fine grinding section 24.

[0089] The tertiary pulverizing section 24 is disposed below the third conveying section 25 and serves to pulverize the scrap particles fed from the third conveying section 25 using a rotating third cutter 26 for pulverization.

[0090] For this purpose, a shaft 37 is disposed inside the tertiary fine grinding section 24, the shaft 37 having at one end a pulley 36 to which power is transmitted from a motor (not shown) and at the same time both ends supported by bearings. A number of third cutters 26 for fine grinding are connected to the shaft 37 disposed in this manner so as to be aligned along the axis while forming a coaxial structure.

[0091] Here, the rotating third cutter 26 for fine grinding is disposed inside the tertiary fine grinding section 24, and is arranged next to the third cutter 26 for fine grinding with a certain gap between them, thereby enabling the scrap particles to be crushed by strongly striking them together with a fixed cutter (not shown) that forms a pair with the third cutter 26 for fine grinding.

[0092] In a preferred embodiment, the tertiary fine grinding section 24 is equipped with a cooling device having a circulation structure with a chiller (not shown), which makes it possible to effectively cool the heat generated when the scrap particles are ground by the third cutter 26 for fine grinding.

[0093] The third cutter 26 for fine grinding of the tertiary fine grinding section 24 is made of a knife-shaped cutter, and such third cutter 26 for fine grinding of the tertiary fine grinding section 24 has a relatively narrower cutter width than the second cutter 23 for fine grinding of the secondary fine grinding section 20, and further has a relatively greater number of cutters, so that the third cutter 26 for fine grinding is able to grind scrap particles even finer than the second cutter 23 for fine grinding.

[0094] As a result, when scrap particles fed from the third conveying section 25 enter the interior of the tertiary fine grinding section 24 during operation of the tertiary fine grinding section 24, the scrap particles are finely ground as they pass between the rotating third cutter 26 for fine grinding and the fixed cutter, and the scrap particles thus ground are sent to the fourth conveying section 28 via the discharge hopper 18c at the lower end of the tertiary fine grinding section 24, and then packaged in the packaging section 27b.

[0095] The fourth conveying section 28 serves to convey the scrap particles that have been subjected to the pulverization process in the tertiary fine pulverizing section 24 to the packaging section 27b side by using a method such as vacuum pressure or suction pressure.

[0096] For this purpose, the fourth conveying section 28 is disposed on one side of the tertiary fine grinding section 24, and the suction side of the fourth conveying section 28 thus disposed is connected to the discharge hopper 18c side in the tertiary fine grinding section 24 by piping 34, while the discharge side is vertically connected to the lower packaging section 27b, for example, the packaging section 27b side equipped with bags (not shown) in which scrap particles can be placed.

[0097] The fourth conveying section 28 includes a pump section 29, and the pump section 29 is capable of sucking in and conveying the screen particles by using the suction force it exerts.

[0098] Here, the pump section 29 is disposed in a structure supported on the upper end of the chamber 31, and the suction side of the pump section 29 is capable of communicating with the inside of the chamber 31, and a mesh screen or the like is interposed between the suction side and the inside of the chamber, making it possible to prevent scrap particles from flowing into the pump side.

[0099] Furthermore, the fourth conveying section 28 is provided with a chamber 31 capable of storing a certain amount of scrap particles that are conveyed and flowed in by a suction method.

[0100] A scrap particle inlet 35 is formed on the side of the chamber 21, and a pipe 34 extending from the discharge hopper 18c of the tertiary pulverizing section 24 can be connected to the scrap particle inlet 35 thus formed.

[0101] The fourth transport section 19 is provided with a damper 30 that can be opened and closed. In this case, the damper 30 can be disposed on the discharge side of the lower end of a chamber 31.

[0102] Here, it is preferable that the damper 30 is opened and closed by the operation of an actuator such as a cylinder.

[0103] As a result, when the damper 30 is closed and the pump section 29 is operated, the suction force causes the scrap particles in the discharge hopper 18c of the tertiary fine grinding section 28 to be transported along the piping 34 and accumulate inside the chamber 31 via the scrap particle inlet 35. When the damper 30 is opened, the scrap particles thus accumulated fall to the bottom and can be placed in bags or the like in the packaging section 27b for packaging.

[0104] 14 to 17 are cross-sectional views showing a cooling device for the secondary and tertiary fine pulverizing sections in a fine pulverizer of a scrap pulverizing and transporting device according to one embodiment of the present invention.

[0105] As shown in Figures 14 and 15, a cooling water chamber 40 is formed inside each cutter holder 39, which is a means for supporting the second cutter 23 for fine grinding in the secondary fine grinding section 20 and is coaxially connected to the shaft 37 and is formed in a form in which a number of cutter holders are combined together. Each cooling water chamber 40 is connected to each other by a flow path 41 to form a structure in which they communicate with each other. A chamber 43 for switching the direction of cooling water, which is connected to the cooling water chamber 40, is also formed inside each holder block 42 which is connected to the shaft 37 while completing the cutter holders 39 located on the periphery on both sides.

[0106] Here, the cooling water chamber 40 and the chamber 43 for switching the cooling water direction are composed of two parts that are independently partitioned, whereby the cooling water chamber 40 and the chamber 43 for switching the cooling water direction in one part are a section through which the cooling water passes while entering, and the cooling water chamber 40 and the chamber 43 for switching the cooling water direction in the remaining other part are a section through which the cooling water passes while exiting.

[0107] At one end of the shaft 37, an inlet side cooling water flow passage 44 is formed which communicates with the cooling water chamber 40 of one part, and at the same time, an outlet side cooling water flow passage 45 is formed which communicates with the cooling water chamber 40 of the remaining other part.

[0108] At one end of such shaft 37, an adapter block 48 is provided which has an inlet 46 and an outlet 47, each of which communicates with a cooling water supply source (not shown) such as a chiller, and which communicates with an inlet side cooling water flow passage 44 and an outlet side cooling water flow passage 45 in the shaft 37.

[0109] This allows the cooling water provided from the cooling water supply source to flow along the path of inlet 46 → inlet side cooling water flow path 44 → one cooling water direction switching chamber 43 → one part cooling water chamber 40 → cooling water direction switching chamber 43 → remaining other part cooling water chamber 40 → remaining other cooling water direction switching chamber 43 → outlet side cooling water flow path 45 → outlet 47 → circulating to the cooling water supply source side, thereby cooling the entire holder block 42 including the second cutter 23 for fine grinding. At this time, a seal 55 and a seal fixing part 56 are provided at the end of the shaft 37 to prevent the cooling water from leaking in.

[0110] The holder blocks 42 are provided at both ends of the cutter holder 39, and the blades 53 are connected to the shaft 37 and rotated at the ends of the holder blocks 42. The blades 53 serve to block the flow of dust generated by the crushing operation of the second cutter 23 for fine crushing toward the bearing 54. More specifically, the secondary fine crushing unit 20 includes an air inlet 58 that allows compressed air supplied by an air compressor (not shown) to flow inside, and the compressed air drawn in through the air inlet 58 flows in the opposite direction to the bearing 54, i.e., toward the center of the cutter holder 39, due to the rotation of the blades 53. In other words, the dust scattered in the gap between the housing 49 and the cutter holder 39 is blocked from being conveyed to the bearing 54 by the compressed air supplied through the air inlet 58 and the blades 53. In addition, a retainer 54 is provided at the end of the bearing, so that dust can be prevented from being sent to the bearing 54 side secondarily.

[0111] Here, if the blade 53 is not provided, there is a problem that dust generated during the pulverization process sticks to the shaft 37 and the bearing 54 through the gap. Therefore, by providing the blades 53 on both ends of the secondary pulverization section 20, it is possible to prevent dust scattering through the gap from moving toward the bearing 54, thereby preventing the dust from sticking to the shaft 37 and the bearing 54 and generating frictional heat due to rotation. As an example, referring to FIG. 14, the blade 53 provided on the right side of the holder block 42 plays a role in preventing dust generated during the pulverization operation by the second cutter 23 for pulverization from moving to the right side by conveying compressed air supplied through the air inlet 58 to the left side. In addition, the retainer 57 is provided on the left side of the bearing 54, and can again prevent dust from moving to the bearing 54. In addition, the flow of the compressed air can cool the secondary pulverization section 20. Here, the supplied compressed air passes through the outer circumferential surface of the holder block 42 and is discharged to the outside of the housing 49, thereby preventing an increase in the internal pressure.

[0112] As shown in FIG. 16, a cooling water chamber 40 is formed inside each cutter holder 39, which is a means for supporting the third cutter 26 for fine grinding of the tertiary fine grinding section 24 and is coaxially connected to the shaft 37 and is formed in a form in which a number of cutter holders are combined together. Each cooling water chamber 40 is connected to each other by a flow path 41, and a cooling water direction switching chamber 43 that communicates with the cooling water chamber 40 is also formed inside each holder block 42 that is connected to the shaft 37 while completing the cutter holders 39 located on the periphery on both sides.

[0113] Here, the cooling water chamber 40 and the chamber 43 for switching the cooling water direction are composed of two parts that are independently partitioned, whereby the cooling water chamber 40 and the chamber 43 for switching the cooling water direction in one part are a section through which the cooling water passes while entering, and the cooling water chamber 40 and the chamber 43 for switching the cooling water direction in the remaining other part are a section through which the cooling water passes while exiting.

[0114] At one end of the shaft 37, an inlet side cooling water flow passage 44 is formed which communicates with the cooling water chamber 40 of one part, and at the same time, an outlet side cooling water flow passage 45 is formed which communicates with the cooling water chamber 40 of the remaining other part.

[0115] At one end of such shaft 37, an adapter block 48 is provided which has an inlet 46 and an outlet 47, each of which communicates with a cooling water supply source (not shown) such as a chiller, and which communicates with an inlet side cooling water flow passage 44 and an outlet side cooling water flow passage 45 in the shaft 37.

[0116] This allows the cooling water provided from the cooling water supply source to flow along a path that circulates from the inlet 46 to the inlet side cooling water flow path 44, from the chamber 43 for switching the direction of the cooling water to one side, from the cooling water chamber 40 in one part, to the chamber 43 for switching the direction of the cooling water, from the cooling water chamber 40 in the remaining other part, to the chamber 43 for switching the direction of the cooling water to the remaining other part, from the cooling water flow path 45 on the outlet side, to the outlet 47, and back to the cooling water supply source side, thereby cooling the entire holder block 42 which includes the third cutter 26 for fine grinding.

[0117] As shown in FIG. 17, a cooling system for the housing 49 of the secondary fine grinding section 20 and the tertiary fine grinding section 24 is shown here.

[0118] A cooling water chamber 40 is formed inside the housing 49, and a cooling water chamber 40 is also formed in each of the housing frames 50 on both sides supporting the housing 49. In this case, each cooling water chamber 40 is connected by a flow path 41.

[0119] The chamber 40 of one housing frame 50 is connected to an inlet nipple 51 for the flow of cooling water, while the chamber 40 of the remaining housing frame 50 is connected to an outlet nipple 52 for the discharge of cooling water, and at this time the inlet nipple 51 and the outlet nipple 52 form a circulation line with the cooling water supply source.

[0120] This makes it possible for the cooling water provided from the cooling water supply source to cool the entire housing 49 by flowing along a path that circulates from the inlet nipple 51 → the chamber 40 of one of the housing frames 50 → the chamber 40 of the housing 49 → the remaining chamber 40 of the other housing frame 50 → the outlet nipple 52 → to the cooling water supply source side.

[0121] Therefore, the operating state of the scrap crushing and conveying device having such a configuration will be described as follows.

[0122] First, scraps of rubber material remaining after making soles for footwear and the like are caught on the hangers 12 in the coarse crushing input section 14 of the coarse crusher 10. Such scraps are crushed into relatively coarse scrap particles and packaged as they pass through the coarse crushing input hopper section 16 → primary coarse crushing section 15 → first conveying section 19 → packaging section 27a.

[0123] Subsequently, the screen particles primarily pulverized in the coarse pulverizer 10 are pulverized into fine scrap particles and packaged, passing through the fine pulverizer 11's fine pulverizing input section 21 → second conveying section 22 → secondary fine pulverizing section 20 → third conveying section 25 → tertiary fine pulverizing section 24 → fourth conveying section 28 → packaging section 27b.

[0124] In this way, the finely ground scrap particles that have been crushed twice and then crushed into fine particles can be provided to various uses and recycled.

[0125] On the other hand, as a preferred embodiment, the present invention provides a layout in which the coarse grinding machine 10 and the fine grinding machine 11 are linked together in the form of an integrated unit in order to realize a continuous automated line for the coarse grinding process by the coarse grinding machine 10 and the fine grinding process by the fine grinding machine 11.

[0126] For this purpose, the coarse crusher 10 and the fine crusher 11 are arranged in series or in parallel on the process line, and the discharge hopper 15a in the primary coarse crushing section 15 on the coarse crusher 10 side is connected to the second conveying section 22 on the fine crusher 11 side by a pipe 34.

[0127] It goes without saying that the first conveying section 19 on the side of the coarse crusher 10 and the fine crushing input section on the side of the fine crusher 11 can be omitted.

[0128] This makes it possible to construct a layout consisting of a continuous automated line in which scrap is primarily coarsely crushed in the coarse crusher 10, and subsequently, the scrap particles discharged after the primary crushing are immediately sent to the fine crusher 11 for secondary fine crushing.

[0129] In this way, by constructing a layout that is realized by linking the coarse crusher 10 for the coarse crushing process and the coarse crusher 11 for the fine crushing process in a continuous automated line, it is possible to maximize the efficiency of the entire process and the efficiency of equipment operation, and it is advantageous in terms of factory layout design.

[0130] As a result, the scrap crushing and transporting device of the present invention has the advantage of being able to crush and transport rubber material such as scrap rubber material left over from the production of footwear soles, waste footwear, etc., for recycling, and also has the advantage of being able to collect dust generated during the crushing process, preventing damage to the crushing device or transporting device from accumulated dust.

[0131] In other words, the present invention provides a new type of scrap crushing and conveying device that crushes scrap such as rubber material generated during the manufacture of footwear soles, etc., using a coarse crushing process in which scrap is primarily crushed into rough particles, and a fine crushing process in which the scrap is secondarily refined into fine particles, and a conveyer that pressure-feeds the crushed particles. This completely solves the problem of environmental pollution and prevents breakdowns caused by dust, and also provides economic benefits by recycling resources.

[0132] In this manner, it should be understood that the technical configuration of the present invention described above can be implemented in other specific forms by a person skilled in the art to which the present invention pertains, without changing the technical ideas or essential features of the present invention.

[0133] Therefore, the above-described embodiments should be understood in all respects as merely illustrative and not limiting, and the scope of the present invention is represented by the claims rather than the above detailed description, and all modifications and variations derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
