The opening and closing member 120 according to the present invention has a first zone Z1 (for example, an extension pipe) between the collecting hopper 111 and the upper end of the moving pipe 114, a middle portion of the moving pipe 114 having a predetermined length in the vertical direction And a third zone Z3 which is a joining portion between the lower end of the moving pipe 114 and the storage drum 211 and is intermittently provided through the control of the control unit 300 It is possible to prevent the backflow of the scrap S to be collected corresponding to the suction force of the dust collecting apparatus 400 or to prevent the backflow of the scrap S to be collected when the storage tank 210 is separated from the moving member 130 400 can be disconnected / combined even when the operation of the controller 400 is performed. That is, even in the process of collecting the scrap S, the dust collector 400 can be continuously operated in an unstable state. At this time, it is preferable that the position and the number of the opening / closing member 120a are determined depending on the length or volume of the traveling path formed by the coupling of the collecting hopper 111 and the moving pipe 114.

6, the opening and closing member 120 may be provided in the second embodiment according to the spatial restriction on the installation of the collection apparatus 1 according to the present invention or the connection position between the transfer tube 114 and the storage drum 211 And may be installed in the collection device 1 in a configuration including the push cylinder 124, the guide body 125, the moving gear 126, the rotary gear 127, and the opening / closing door 128.

The push cylinder 124 is fixed inside the lower portion of the moving pipe 114. When the lever switch 310 is operated through the control of the control unit 300, the pushing cylinder 124 is pulled by the control of the control unit 300 And closes the open portion 117 opened so that the moving tube 114 and the storage drum 211 can communicate with each other by the rotation of the opening / closing door 128 which is pulled and rotated. At this time, it is preferable that the opening 117 is formed in the outer surface of the storage drum 211 connected to the lower end of the moving pipe 114 or the lower portion of the moving pipe 114.

The guiding body 125 is fixed to the inside of the moving pipe 114 so as to be positioned below the moving gear 126 and a part of the lower surface of the moving gear 126 is slidably inserted so that the rod of the push cylinder 124 is tensioned / And helps the moving gear 126 to reciprocate stably during contraction.

The moving gear 126 is formed to have a generally rectangular parallelepiped shape such as a rack gear and is disposed so that it can be guided and guided by the guide body 125. The rotating gear 127 and the teeth And the outer surface of which is fixed to the rod of the push cylinder 124 and can be reciprocated by the push cylinder 124. [

The rotary gear 127 is disposed so as to be able to engage with a gear groove formed on the upper surface of the moving gear 126 so as to be connected to the rotation shaft of the opening and closing door 128, And opens and closes the opening 117 through the area of the opening and closing door 128 having a plate shape by rotating in the forward direction or the reverse direction according to the moving direction.

The opening and closing door 128 is formed to have a plate shape as a whole and is axially coupled to be rotatable inside the moving pipe 114. The rotary gear 127 is installed to open 117 are opened and closed. The lower portion of the moving pipe 114 is partially inserted into the storage drum 211 to increase the airtightness of the scrap S to be collected and the opening 117 is formed inside the moving pipe 114 It is preferable to make it possible to form it.

At the same time when the opening / closing door 128 is opened, external pressure (pneumatic pressure) is discharged into the moving tube 114 through the nozzle 116 described above to form a lightweight film, It is possible to make it easier to discharge the scrap S toward the storage drum 211.

The opening and closing members 120a and 120b according to the first and second embodiments may be divided into a plurality of space portions having at least one or more predetermined lengths according to the length of the traveling path, The length of the divided space part is variable according to the opening and closing of the opening and closing members 120a and 120b.

7 to 10, in a state in which the opening and closing member 120 is omitted, as shown in Figs. 7 (a) and 8 (a), the dust collecting device 400, When the scrap S is drawn into the cylindrical collecting hopper 111 by the suction force of the scrap S, the foreign substances in the form of particles are absorbed into the dust collecting apparatus 400 through the discharge pipe 113, A part of the scrap S which has flowed into the storage tank 210 due to the suction force of the dust collecting apparatus 400 is moved back to the storage drum 211 as the traveling path is shorter, 7B, the length of the traveling path is maximized, so that the dust collecting device (the dust collecting device) 400 is weakened toward the lower portion of the moving pipe 114 However, this method has a problem in that it can not be used in a place where the installation space is limited.

In order to overcome this, as shown in Fig. 8 (b), one or a plurality of opening and closing members 120a are provided adjacent to each other in the middle of the moving path, and the moving paths alternately open and close intermittently, The length of the traveling path can be kept as short as possible while preventing the reverse flow phenomenon.

That is, after a certain amount of the scrap S is sucked into the traveling path by the suction force of the dust collecting device 400, the opening and closing member 120a of the first zone Z1 is closed and the opening and closing member 120a of the second zone Z2 is closed And the installed opening and closing member 120a is maintained in the open state (see Fig. 9).

The space portion of the upper portion (including the inside of the collecting hopper) is continuously maintained in a state of sucking the scrap S from the outside with reference to the opening and closing member 120a of the first zone Z1, The scrap S can not collect the suction force of the dust collecting apparatus 400 and can be collected in the storage tank 210 by its own weight so that the back flow phenomenon can be prevented.

Of course, the shutoff member 120a of the closed first zone Z1 is opened and the shutoff member 120a of the second zone Z2 is continuously operated in the repetitive operation of performing the closed state, (S) can be collected.

However, in the case of the embodiment through the one or the pair of gap members 120a described above, when the lengths D1 and D2 of the traveling path are short, the volume of the other space portion, that is, the collection capacity of the scrap S, In order to overcome this problem, another opening / closing member 120b is provided in the third zone Z3, which is the lower end of the moving pipe 114, and the lower volume of the moving pipe 114 is relatively increased, S) can be collected. At this time, the opening / closing member 120b installed in the third zone Z3 may be installed with the opening / closing member 120a having the configuration of the first embodiment, Closing member 120b of the second embodiment that can be installed inside the moving pipe 114 so as to reduce the time difference when the moving member 121 is moved and quickly open and close the opening member 120, It is preferable that the opening and closing member 120a and the opening and closing member 120b provided in the third zone Z3 are opened and closed in the same manner.

However, when the plurality of the opening and closing members 120a and 120b are alternately opened and closed, a backflow phenomenon of another scrap S may occur due to a pressure difference in each of the divided spaces.

That is, as shown in the drawing, when the opening and closing member 120a of the first zone Z1 is in the closed state, the internal pressure of the space portion (collecting hopper portion) corresponding to the upper portion of the opening and closing member 120a, 400 (see FIG. 8), as compared with the pressure of the space portion (moving pipe portion) corresponding to the lower portion of the opening and closing member 120a.

In this state, when the opening and closing member 120a of the first zone Z1 is opened, the scrap S in the space portion (moving pipe portion) corresponding to the positive pressure partially flows back to the space portion (collecting hopper portion) .

Of course, the backflow phenomenon related to the pressure difference may cause the same problem when the opening and closing members 120a and 120b are installed in any one of the first to third zones Z1, Z2 and Z3.

To solve this problem, the pressure inside the space portion (moving pipe portion) corresponding to the positive pressure is artificially absorbed by the pressure regulating member 140, which will be described later, to maintain the same pressure as the pressure of the space portion (collecting hopper portion) And adjusting the pressure to be lower than the value of the corresponding sound pressure, thereby solving the problem. At this time, though not shown, a pressure sensor (not shown) is provided in each of the space portions to adjust the pressure to be sucked into the pressure regulating member 140 through the control of the controller 300.

Further, since the scrap S can stay in the traveling path for a predetermined time due to the installation of the opening and closing members 120a and 120b, the closing of the opening and closing members 120a and 120b causes the storage tank 210 can be additionally secured.

11, the moving member 130 is configured to provide a space in which the storage unit 200, which will be described later, can be installed and moved, and to allow the collection device 1 of the present invention to move to a workplace, (131), wheels (134), and a feed rail (135).

The moving body 131 is formed to have a rectangular frame shape as a whole through the combination of the plurality of vertical frames 132 and the horizontal frame 133 and a space for providing a space for installing the storage unit 200 therein is formed . At this time, a plurality of wheels 134 that can be moved and stopped can be installed below the horizontal frame 133, which is close to the ground, and a pair of conveying rails 135 are installed adjacent to each other on the upper surface thereof. So that the engaging member 220 formed at the lower portion of the storage tank 210 can be slid by the conveying rail 135.

The length of the horizontal frame 133 is set such that the collecting apparatuses 1 according to the present invention are installed adjacent to each other and a sufficient space is formed between adjacent ones of the storage tanks 210 for separating / And can be formed so as to have a length enough to allow the scrap S to be taken out and discarded (see Fig. 12).

Referring to FIG. 13, the pressure regulating member 140 includes a plurality of open / close members 120 adjacent to each other in the moving path, so that when the moving path includes a plurality of space portions, A first valve 142 and a second valve 143 in order to allow the scrap S to be collected to be easily collected into the storage tank 210 by adjusting the amount of the scrap S to be collected. That is, the pressure regulating member 140 sucks the internal pressure of the space portion so that the scrap S relatively moves in the direction in which the scrap S is intended to move, so that the scrap S can move in the negative pressure direction from the positive pressure (See FIG. 8).

The blower 141 may be fixedly mounted on the moving body 131 so as to be controllable by the controller 300 and may include a first valve 142 as well as a tube having a predetermined length, And is connected to the second valve 143 through the suction line of the shape.

The blower 141 operates under the control of the control unit 300 to discharge the atmospheric pressure to the discharge line by the first valve 142 which can be opened and closed normally (when the internal pressure of the space portion is not sucked) The second valve 143 is provided with a structure capable of selectively sucking in the pressure sucked into the suction line after sucking the internal pressure of the space by the second valve 143 which can be opened and closed. At this time, it is preferable that the blower 141 is installed so that the silencer 144 can prevent atmospheric pressure or noise that may be generated when discharging the sucked internal pressure.

The first valve 142 is connected to the discharge line so as to be openable and closable under the control of the controller 300 and is opened so that the atmospheric pressure of the outside is sucked by the blower 141 and discharged to the outside through the silencer 144 , And the second valve (143) is automatically closed through the control unit (300) during operation.

The second valve 143 is connected to the suction line to be openable and closable under the control of the controller 300 and is opened so that the internal pressure of the space portion is sucked by the blower 141 and discharged to the outside through the silencer 144. [ And the first valve 142 is installed so that it can be closed automatically during operation through the control unit 300. At this time, one end of the suction line is connected to the protrusion pipe 115 protruding from the moving pipe 114 forming a space portion to absorb the internal pressure, and has a structure capable of absorbing the pressure through the cavity 118 desirable.

The pressure regulating member 140 may further include a supply valve 145 that can be controlled by the control unit 300. The supply valve 145 may include a plurality of protruding pipes 115 So that the pressure can be controlled by providing atmospheric pressure to the space portion.

In addition, the supply valve 145 is used when a plurality of the opening and closing members 120a and 120b are installed so as to open and close the traveling path.

The opening and closing member 120a provided in the first zone Z1 is closed and the opening and closing members 120a and 120b provided in the second zone Z2 and the third zone Z3 are closed, The pressure in the second zone Z2 is relatively lower than the pressure in the third zone Z3 even in the same space portion so that the collected scrap S can be easily moved to the storage tank 210. [ The scrap S collected can be easily moved.

In order to satisfy such a criterion, the controller 300 opens the supply valve 145 to provide an external air pressure (atmospheric pressure) so that the pressure in the second zone Z2 is higher than the pressure in the third zone Z3 So that the scrap S can be easily moved.

14 to 18, the storage unit 200 collects a large amount of scrap S collected through the above-described moving path so that the scrap S is not collected in one direction, A coupling member 220, and a compression member 230 in order to increase the collection amount of the storage tank 210, the storage tank 210, the coupling member 220, and the compression member 230.

15 and 17, the storage tank 210 is formed so as to have a hollow cylindrical shape as a whole, and the opened upper portion can be separated / joined to the lower portion of the storage drum 211 having a tubular shape The scrap S collected through the traveling path is introduced into the storage tank 210 and the scrap S collected by the pressing plate 235 can be compressed.

The outer surface of the storage drum 211 is structured such that the scrap S which moves with the lower part of the moving pipe 114 and moves through the moving path can be introduced into the storage tank 210 and the moving body 131, And a compression member 230 is installed on the upper portion of the storage drum 211 so that the compression member 230 can be lifted and lowered.

A plurality of knobs are radially formed on the outer surface of the storage tank 210 to allow the operator to move the storage tank 210 in and out of the installation space in any direction and to dispose of the compressed scrap S therein It is easy to do.

The lower part of the storage tank 210 is fixed to the coupling member 220 and a rotary shaft 212 for rotating the storage tank 210 is axially coupled through a driving motor or a cylinder, Thereby rotating the storage tank 210. At this time, the rotation angle of the storage tank 210 is a structure in which the scrap S to be stored in the storage tank 210 can be stacked as a whole by rotating the storage tank 210 in one direction or in both directions with intervals of 20 to 45 degrees .

In the lower part of the storage tank 210, a moving means for easily moving the storage tank 210 into / out of the installation space is formed along the transfer rail 135. The moving means includes a guide plate 213, A bracket 214, and a moving roller 215. As shown in Fig.
