Description

[0001] The present invention relates to an auto diverter for change of direction,

The present invention relates to an auto diverter for redirecting, which is applied to change the conveying direction of an article during conveyance of the article using the conveyor.

Generally, a conveyor belt or a conveyor roller is used to continuously convey articles from the production line to the unloading operation or from the production line. At this time, in order to facilitate the work or the space characteristic of the work site, there is a case that the direction of conveyance of the article needs to be changed and transferred.

To this end, in Korean Patent No. 0846681, there is disclosed a chain conveyor comprising a plurality of chain plates which are linearly transported and fixed by a driving means, and which are foldably connected by a fixing pin; A pair of brackets fixed to the outer surface of the chain plate by the fixing pins symmetrically in the front and rear direction on the lower side and inclined to the inside of the plate as the upper side fixing piece; A stopper roller rotatably installed in front of the chain type conveyor and stopping the conveyance of the article W conveyed along the chain type conveyor and using a idler roller or a driving roller rotated by the driving means; And an article W which is inclined at an angle of 45 degrees in a diagonal direction with respect to the bracket and is rotatably fixed and conveyed along the roller type conveyor and then stopped by a stopper roller rotatably installed in front of the chain type conveyor, And a direction changing roller for changing the direction of rotation of the chain conveyor by 90 degrees by a frictional rotational force.

However, according to the patent, since the brackets have to be formed along the chain plate in order to install the direction changing roller, the structure is complicated and the load of the article is supported only by the bracket, so that there is a problem that the bracket is likely to be damaged. Further, in the case of an article having a large size, regardless of whether the interval between the chain plates is wide, in the case of articles having a small size, if the interval between the chain plates is wide, the article can be inclined between the intervals. Therefore, there is a problem that they can not be used together for transporting articles of different sizes. Further, although it is possible to consider adjusting the distance between the chain plates depending on the size of the article, there is a problem that it takes much time to install a new chain plate.

On the other hand, Japanese Utility Model No. 3031857 discloses a slat conveyor in which slate plates are provided with a plurality of cutouts each having a rectangular shape inclined by 45 占 with respect to the longitudinal direction, and the roller is rotatably supported on the cut- And the roller is circumferentially inclined at an angle of 45 deg. With respect to the longitudinal direction of the slat plate so that the rollers are inclined at an angle of 45 DEG with respect to the longitudinal direction of the slat plate State, and a stopper is provided on one side of the corner tray.

However, according to this structure, since both ends of the slate plate are coupled to the chain, the length of the slate plate must be long to transport the large-sized article. However, the slate plate can not support the load of the article and is bent.

The back surface of the slate plate can be supported by a separate support member, but another problem arises that the transfer of the slate plate is hindered by the support member.

Since the roller plate is attached to the plate, the plate is easy to bend when supporting a heavy article, and even if the plate is not bent, It is installed only on one side, and the roller is liable to move upward and downward, so that the product can not be reliably supported.

Further, when the article enters the corner transporter through the linear conveying conveyor or advances to the linear conveying conveyor, there is a problem that the corner transporter and the linear conveying conveyor are spaced apart from each other and the article can not be connected smoothly.

In addition, when the stopper is fixed and the direction of advancing in a straight line feed in the curved line feed is changed, since the stopper must be dismantled, the advancing direction can not be changed quickly, resulting in a deteriorated workability.

Accordingly, it is an object of the present invention to provide an auto diverter for one-way switching so that a large-size and heavy-weight article can be sufficiently supported while being reliably transported.

It is another object of the present invention to provide an auto diverter for changing direction so that an article can be smoothly connected with a linear conveying conveyor.

It is another object of the present invention to provide an auto diverter for redirecting a direction in which an advancing direction can be quickly changed.

The above object can be attained by a chain conveying apparatus comprising a housing provided in a receiving space therein and provided with a support member transversely extending in the longitudinal direction, a chain-type conveying unit mounted in the receiving space for carrying the article linearly in a first direction, And an advancing control unit provided at one side of the unit and including a stopper roller unit for stopping the linear movement of the article, wherein the chain-type conveying unit comprises: an endless chain column for performing an endless orbit movement by a driving device; A transfer plate disposed along the chain row and having both longitudinal ends coupled to the chain row to perform the endless track movement; A direction changing roller of elastic material mounted on the conveying plate and supported in contact with the article and rotating in a second direction at a predetermined angle with respect to the first direction; And a support roller protruding from the upper surface of the transfer plate so as not to contact the article and lower than the direction changing roller and being mounted to protrude from the lower surface of the transfer plate and to rotate in the first direction, Wherein at least one support roller insertion hole facing the first direction is formed through the transfer plate and a support roller bracket is integrally bent at the lower surface of the transfer plate at opposite sides of the support roller insertion hole in the longitudinal direction, And the support roller is rotatably axially coupled to the support roller bracket between the support roller brackets.

Preferably, a plurality of cutting holes facing the second direction are formed along the longitudinal direction of the transfer plate, and the direction changing roller brackets are integrally formed on the upper surface of the transfer plate at opposite sides of the cut- And the direction changing roller is mounted between the direction changing roller brackets so as to be axially coupled to the direction changing roller bracket.

Preferably, the advance control unit further includes an elevating unit for elevating and lowering the stopper roller unit, and more preferably, the elevating unit includes a bar connecting the both pillars to the upper ends of the pillars, A structural frame composed of a steel plate installed vertically movably; A lifting cylinder device in which a cylinder is installed in the bar and an end of the piston is coupled to the lifting plate; And a guide installed through the bar so as to guide the lifting and lowering of the lifting steel plate and the lower end of which is coupled to the lifting steel plate.

Preferably, at a boundary portion with the rectilinear conveying conveyor adjacent to the redirecting auto-diverter, the rectilinear conveying conveyor is installed in the housing to enter the redirecting auto-diverter from the rectilinear conveying conveyor, And may further include a connection roller for accelerating the article advancing to the first position.

According to the above structure, when the article is large in size and heavy in weight, a large load is applied to the transfer plate through the direction changing roller. However, since the load applied to the transfer plate is applied and concentrated on the support plate through the support roller, So that the conveyance of the article is smoothly performed.

Further, since the support roller is mounted in the transport direction and does not contact the article, the support roller rolls on the support table while the load of the article is transmitted through the feed plate, and does not interfere with the movement of the feed plate.

In addition, a connecting roller is provided between the edge of the redirecting autoduberer and the linear conveying conveyor, so that the article smoothly enters the redirecting autodubter at the linear conveying conveyor or advances from the redirecting auto-diverter to the linear conveying conveyor .

In addition, the stopper roller unit can be moved upwards to secure a path for straight-line feeding, so that the advancing direction can be changed from straight-line feeding to straight-line feeding.

In the following description, the direction in which the article enters the direction changing auto-changer 10 or advances in a straight line is referred to as a transporting direction and the direction in which the article advances at a right angle from the direction switching auto-diverter 10 is referred to as a switching direction.

The orientation redistributor 10 is composed of a chain type transfer unit 100 and a housing 200, and may optionally include an advance control unit 300.

Hereinafter, each component will be described in detail.

<Housing 200>

The housing 200 is box-shaped with an upper portion opened and a storage space 202 formed therein. The chain type transfer unit 100 is housed in the inner space 202 and the advance control unit 300 is installed on one side.

Since the housing 200 can be constituted as a single body and can be moved, it can be easily fixed at a necessary position. In other words, it is disposed between a linear conveying conveyor such as a conventional chain conveyor or a rolled conveyor to change the direction.

A plurality of connection rollers 220 for accelerating the entry of the articles 50 are provided side by side on the entry side edge of the housing 200 and a plurality of connection rollers 222 for accelerating the entry of the articles 50 are provided on the leading side edge, Are installed side by side. Although the connection rollers 220 and 222 are shown together with the chain type transfer unit 100 in FIG. 1, the connection rollers 220 and 222 are installed in the housing 200 separately from the chain type transfer unit 100.

Each of the connection rollers 220 and 222 is spaced apart from the chain conveying unit 100 and is spaced apart from the adjacent linear conveying conveyor so as to be positioned at an intermediate position between the conveying rollers 220 and 222 so that the product 50 smoothly moves to the orientation auto- So as to advance from the entering or changing direction autodilver 10.

A reinforcing member 210 crossing the width direction and a support base 212 crossing the longitudinal direction are installed in the interior accommodating space of the housing 200. The support base 212 extending in the longitudinal direction in the middle in the width direction, And indirectly supports the transfer plate 140 by contacting the support rollers 152 with the chain-type transfer unit 100, as in the case of FIG.

&Lt; Chain type transfer unit 100 >

The chain-type transfer unit 100 includes a drive unit and a transfer plate 140, a direction switching roller 150, and a support roller 152.

The drive unit is composed of a drive motor 102, a drive shaft 110 that is rotated by the drive motor 102, a driven shaft 120, and an endless chain column 130 that power-connects the drive shaft 102 and the driven shaft.

The chain train 130 may be provided with a bracket 132 extending laterally horizontally so that the transfer plate 140 is easily engaged.

The transfer plate 140 is literally formed of a single body 141 and is of a plate shape having a narrow width and a long length, and the length is determined by the interval between the rows 130 of both side chains, and the width can be designed arbitrarily. The transfer plate 140 is fixed to the brackets 132 of the chain row 130 at both ends thereof with bolts or the like.

Fig. 3 (a) shows the upper surface of the transfer plate 140, and Fig. 3 (b) shows the lower surface of the transfer plate 140. Fig.

A rib 148 protrudes to the lower side of the conveyance plate 140 at a widthwise edge thereof to reinforce the strength of the rib 148. The rib 148 is formed to be lower than the height of the support roller 152 described later.

A plurality of direction change roller insertion holes 142 are formed along the lengthwise direction of the transfer plate 140. The direction changing roller insertion holes 142 are formed at an acute angle, for example, 45 degrees with respect to the longitudinal direction.

The direction changing roller brackets 143 are integrally bent and upward from the transfer plate 140 to the upper surface on both sides of the direction changing roller inserting holes 142 on the opposite sides in the longitudinal direction, And the roller 150 is installed to be axially coupled to the direction changing roller bracket 143. As a result, the orientation roller 150 is mounted at an angle of 45 degrees with respect to the longitudinal direction of the transfer plate 140.

According to this structure, since the direction changing roller brackets 143, which are integrally bent and integrally bent from the transfer plate 140, support both ends of the direction changing roller 150 in pairs, Even if the weight of the article 50 is large, the direction changing roller 150 can be reliably supported without shaking.

In the direction changing roller 150, the size of the roller, the spacing between the rollers, and the like can be appropriately designed, and the material is not particularly limited, and metal, plastic, urethane or the like can be applied.

In this embodiment, a support roller insertion hole 146 is formed in the middle of the conveying plate 140 in the lengthwise direction, and a support roller insertion hole 146 is formed in the support roller insertion hole 146, A pair of support roller brackets 147 which are integrally bent and erected integrally are protruded and a support roller 152 is axially coupled between the support roller brackets 147. [

The support roller 152 protrudes from the upper surface of the transfer plate 140 but the product 50 protruded lower than the direction changing roller 150 and supported by the direction changing roller 150 contacts the support roller 152 It is important not to.

4, the support roller 152 is brought into contact with the support table 212 and is rolled. At this time, the load applied to the transfer plate 140 by the article 50 is transmitted to the direction change roller 150 through the transfer plate 140 -> support roller 152 -> support 212.

As a result, since the support table 212 receives the load of the article 50 intensively, it is possible to prevent the transfer plate 140 from being bent by the load of the article 50 and to prevent the movement of the transfer plate 140 Do not.

If the support roller 152 is not rotated because the rotation of the support roller 152 is disturbed by the weight of the article 50 when the support roller 152 is in contact with the support roller 152, 152 are slid on the support table 212 to increase the frictional force, and as a result, disturb movement of the transfer plate 140.

On the other hand, a guide roller unit 230 is installed at one side edge of the housing 200 along the conveying direction, so that the conveyed article is not released to the outside. The guide roller unit 230 is composed of a plurality of rollers and a bracket for supporting the rollers, and each roller is formed at an appropriate height corresponding to the size of the article to be transported.

The size and spacing of the rollers can be suitably designed, and the material is not particularly limited, but metal, plastic, urethane or the like can be applied.

&Lt; Entry Control Unit 300 >

The advance control unit 300 includes a stopper roller unit 310 provided to be movable up and down, and optionally includes a lifting unit for lifting and lowering the stopper roller unit 310.

The stopper roller unit 310 prevents the article 50 conveyed by the chain-type conveying unit 100 from further proceeding, and comprises a plurality of rollers and brackets for supporting the rollers, As shown in FIG.

The size of the roller, the spacing between the rollers, and the like can be appropriately designed, and the material is not particularly limited, and metal, plastic, urethane or the like can be applied.

The elevating unit performs a function of raising or lowering the stopper roller unit 310 upward.

The elevating unit includes a bar 323 connecting the both columns 321 and the upper ends of the columns 321, a structural frame 320 composed of a lift plate 322 vertically movable between both columns, A lifting cylinder device 330 in which a cylinder 331 is installed and an end of the piston 332 is coupled to the lifting and lowering plate 322 and a bar 323 for guiding lifting and lowering of the lifting and lowering plate 322, And guides (340, 342) that engage the steel plate (322).

With this configuration, the lifting plate 322 is lifted or lowered by the cylinder device 330 operated by hydraulic pressure or pneumatic pressure. As will be described later, a passage is formed between the two pillars of the structure frame 320 at the time of lifting And is in close contact with one side of the chain-type conveying unit 100 at the time of descending.

Hereinafter, the operation of the redirecting auto-diverter of the present invention will be described with reference to Figs.

Fig. 5 illustrates the operation of the redirecting auto-diverter.

The direction of arrow A indicates the direction in which the article enters and is linearly transported. The direction of the arrow B indicates the direction in which the article advances and advances while passing through the direction switching auto-diverter 10, 10, and advances without switching directions.

As described above, the direction changing roller 150 is mounted at an angle of 45 degrees with respect to the switching direction, that is, the longitudinal direction of the transfer plate 140. When the transfer direction is taken as a reference, an angle of 135 degrees with respect to the transfer direction is formed .

The redirecting auto-diverter 10 is arranged in the middle of a rectilinear conveying conveyor 20, 40 arranged so as to be parallel to each other and a rectilinear conveying conveyor 30 arranged to be perpendicular to them.

Therefore, when the linear conveying conveyor 20 advances from the linear conveying conveyor 30 to the linear conveying conveyor 40, it becomes a simple linear conveying, and when the linear conveying conveyor 20 advances from the linear conveying conveyor 20, it becomes a curved conveying.

When the article 50 enters the direction switching autotiver 10 along the direction of arrow A through the linear conveying conveyor 20, the connecting roller 220 contacts the lower surface of the article to accelerate the article 50 with frictional force Raise it up on the redirector (10).

In this state, the article 50 comes into contact with the direction changing roller 150 and presses the direction changing roller 150 by its own weight. As described above, the direction changing roller 150 moves in the direction of 135 degrees The direction changing roller 150 is linearly moved along the conveying plate 140 which performs the endless track movement by the chain train 130 in a state that the direction changing roller 150 is not rotated due to the weight of the article 50. [

At this time, when the article 50 is large in size and heavy in weight, a large load is applied to the transfer plate 140 through the direction changing roller 150. However, as described above, The transfer plate 140 is not bent and the transfer of the article 50 is smoothly performed because the transfer plate 140 is applied and concentrated on the support table 212 through the roller 152. [

The support roller 152 is mounted in the conveyance direction and does not contact the article 50. Even when the load of the article 50 is transmitted through the conveyance plate 140, And does not interfere with the movement of the transfer plate 140 while rolling over the transfer plate 212.

The linearly moving article 50 guided by the guide roller unit 230 on the direction changing auto-diverter 10 is stopped by the stopper roller unit 310 at the front end in the conveying direction, The transfer plate 140 continues its endless orbital motion by the chain row 130. As a result, the direction changing roller 150 and the rollers of the stopper roller unit 310 are rotated together by the article 50.

5, when the conveying plate 140 is stopped, the direction switching roller 150 rotates in the direction a, and the roller of the stopper roller unit 310 rotates in the direction b, I.e., in the direction of the arrow B, and is linearly conveyed along the linear conveying conveyor 30. The linear conveying conveyor 30, as shown in FIG.

Here, as described above, the direction changing roller 150 is mounted so as to form the angle of 45 degrees with respect to the switching direction, and may be changed to form another suitable angle. In particular, since the rotational force may vary depending on the number of the rollers of the stopper roller unit 310 and the number of the direction changing rollers 150, the angle at which the direction changing roller 150 is disposed can be adjusted in consideration of this.

On the other hand, when the article 50 is to be linearly conveyed without being curved, the up switch is turned on in the control panel (not shown) to drive the cylinder device 330 and the connected piston 332 ascends, The lifting plate 322 coupled to the end of the lifting plate 332 is lifted.

As a result, the stopper roller unit 310 coupled to the lower surface of the lifting plate 322 is also lifted so that a passage is formed between both the pillars 321 of the structural frame 320, To advance to the straight conveying conveyor 40 through the conveying path.

On the contrary, when the down switch is turned on to drive the cylinder device 330, the stopper roller unit 310 moves downward to be in close contact with one side of the chain-type transfer unit 100.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

For example, in the above embodiment, the direction changing roller inserting hole is formed in the conveying plate for installing the direction changing roller, but a pair of brackets may be provided so as to protrude from the upper surface of the conveying plate without forming the inserting hole, The direction changing roller can be rotatably installed.

Further, in the case of the support rollers, it is also possible to provide the pair of brackets so as to protrude from the lower surface of the transfer plate without forming the support roller insertion holes, and the support roller can be rotatably installed therebetween.

Accordingly, the scope of the present invention should not be construed as being limited to the embodiments described above, but should be construed in accordance with the following claims.
