Description

Conveying device

Technical Field

The utility model relates to a device, in particular a conveyor device for sealing batteries or battery parts.

Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Due to the high environmental concerns, efforts to reduce carbon emissions are spreading worldwide. In order to reduce carbon emissions, the production of automobiles equipped with combustion engines that burn fossil fuels to obtain power has been continuously reduced, and on the contrary, the production of electric automobiles that use electric power to obtain power has been continuously increased.

The demand for batteries mounted to electric vehicles and storing electric power is continuously increasing. On the other hand, in the case where the use of personal mobile devices such as smartphones and tablet computers is becoming daily, there is a continuous increase in the demand for batteries for supplying power to the mobile devices.

As the demand for these batteries increases, research and development on batteries is vigorously progressed.

The battery may include a body and an electrode mounted to the body. The electrode may include a positive electrode and a negative electrode. A gap between the body and the electrode may occur at a portion of the battery where the electrode is mounted, i.e., an electrode portion. Since the contents (e.g., electrolyte) inside the body can flow out through these gaps, it may be necessary to seal these gaps.

Therefore, in the production process of the battery, the operation of sealing the electrode portion can be performed. Such sealing operation can be performed by a conveying device having a sealing function.

In such a conveying device, for example, a pair of conveyor belts are provided to be separated from each other by a gap. The battery may be inserted between the conveyor belts before the sealing operation is performed. Then, the battery may be moved by the rotation of the conveyor belt while being pressurized and heated.

The conveyor belt is used under high pressure conditions and therefore needs to be periodically replaced. To replace the conveyor belts, it may be necessary to further expand the spacing between a pair of conveyor belts. For this reason, a disassembly operation for disassembling a part of the conveying apparatus or moving a part of the components of the conveying apparatus may be required.

When the disassembly work of the conveyor is performed and the conveyor is reassembled after the replacement of the conveyor, the components of the conveyor may be impacted or impacted against each other. As a result, the components of the conveying device may be worn or damaged, and the durability of the conveying device may be reduced.

In addition, since disassembly and reassembly operations of the conveying device undergo a process of disassembling and reassembling a plurality of components, a structure capable of shortening the time of these operations is required.

Disclosure of Invention

Technical problem

The present utility model therefore aims to provide a device, in particular a conveyor device for sealing batteries or battery components, having a structure capable of reducing the impact between the components when the conveyor belt is replaced.

In addition, the present utility model aims to provide a device, particularly a conveying device for sealing a battery or battery parts, having a structure that reduces the time required for the operation by easily performing disassembly and reassembly.

The objects of the present utility model are not limited to the above objects, and other objects and advantages of the present utility model, which are not mentioned, can be understood by the following description, and can be more clearly understood by the embodiments of the present utility model. Further, it is to be understood that the objects and advantages of the present utility model can be realized by means of the instrumentalities and combinations particularly pointed out in the appended claims.

Technical proposal

The present utility model provides an apparatus for sealing a battery or battery component.

The apparatus (e.g., device or system) for sealing a battery or battery component of the present utility model may be used to seal a battery or battery component (particularly a battery cell) (e.g., a battery or battery component may be sealed). For example, the device may seal a gap between the body of the battery or battery component and the electrode.

Hereinafter, for the sake of brevity, when referring to the battery or battery component, only the term "battery component" is used. Thus, the term "battery component" includes not only the entire battery but also a portion of a battery such as a battery cell.

The device includes a first conveying section and a second conveying section, which may be collectively referred to as the "conveying section" of the device. Thus, the device of the present utility model may also be referred to as a delivery device. The first and second transport portions may each include a tool for moving the battery component. In particular, the first and second conveying sections may each include a conveyor belt for moving the battery parts. In another example, the first and/or second conveyor may not include a conveyor belt, but may receive, support, or drive the conveyor belt. Additionally, the first and second conveying sections may include other means for moving the battery parts, such as a roller conveyor or a moving base.

The first and second conveying portions may be disposed opposite each other, for example, may be separated or spaced apart to a gap size for disposing the battery parts. The first and second transport portions may seal the battery component therebetween. In particular, for example, the first and second conveying portions may include means for heating or applying pressure to the battery parts, respectively, to perform a sealing operation during movement of the battery parts. In some examples, the tool for moving the battery component (e.g., a conveyor belt) may also heat or apply pressure to the battery component by generating and transferring heat or pressure to the battery component.

The conveying device further includes a first drive shaft for driving the first conveying portion. For example, the first drive shaft may be coupled with a drive motor for rotating the first drive shaft in a direct connection or in an indirect connection through a drive member such as the first drive member. The first drive shaft may, for example, drive a member of the first conveying section for moving the battery part so as to move the conveyor belt or run the roller conveyor by rotating the first drive shaft. The first drive shaft may be fixed. In particular, the first drive shaft may not move when adjusting the spacing between the first conveying portion and the second conveying portion.

For example, the conveyor further comprises a second drive shaft similar to the first drive shaft described above for driving the second conveyor. The second drive shaft is partially moved relative to the first drive shaft to adjust the spacing between the first and second conveying portions. For example, the second drive shaft may extend through a gap between the first conveying portion and the second conveying portion, or may be partially moved in a first direction connecting the gaps. The first direction may be inclined with respect to the axis or length direction of the second drive shaft. The second drive shaft may be partially movable, for example, by a distance of 2mm to 100mm, preferably 5mm to 50mm, more preferably 10mm to 30mm, i.e. the distance between the first and second conveying sections may be adjusted to the respective distance. Adjusting the spacing may allow for improved access to components of the apparatus, such as the first and second transport sections, to accommodate different sized battery components, or as a service provision or replacement of components such as a conveyor belt or roller conveyor, for example.

The delivery device further includes a second drive member coupled to the second drive shaft. For example, the second driving member is engaged with an action part coupled to a driving motor for rotating the second driving shaft to transmit a rotational motion, such as a torque or a rotational force, from the action part to the second driving shaft. The action member may be included in the conveying device or an external member provided together with an external driving motor. In some examples, the second drive member may be engaged with the actuation component. The second driving member may be coupled to the second driving shaft such that the second driving member rotates together with the second driving shaft. The second drive member may be disposed on the second drive shaft or connected or attached to the second drive shaft. In some examples, the second drive member, the second drive shaft, or a portion thereof may be integrally formed. For example, the second drive member or action component may be or include a gear, worm or screw or other suitable gear or transmission member known in the art.

The second drive shaft may include more than three links, i.e., at least a first link, a second link, and a third link. Each of the links may include a shaft portion.

The first link is coupled to the second driving member. Instead of rotating about an axis, the first link may not be movable.

The second link moves relative to the first link to cause the second drive shaft to move partially relative to the first drive shaft. For example, the second link may be movable in a first direction or obliquely, in particular perpendicular to the axis or length direction of the first link or the second link. The second link may move without tilting, i.e. the rotation axis of the second link may remain parallel to the initial direction. In some examples, the axis of rotation of the second link may be always parallel to the axis of rotation of the first link.

The third connecting rod is respectively combined with the first connecting rod and the second connecting rod. The third link may be disposed between the first link and the second link and connect the first link and the second link to transmit rotational movement between the first link and the second link. As the second link moves relative to the first link, the third link tilts relative to the first link and the second link. Thus, the third link may allow the second link to move relative to the first link. The third link may be formed obliquely (e.g., rotated to an inclination angle of less than 360 °) with an inclination angle, particularly, an axis perpendicular to the axis of the first or second link as a center. For example, the third link may be inclined at an angle of 2 ° to 90 °, preferably 5 ° to 45 °, more preferably 10 ° to 20 °. The length of the third link may be 10mm to 500mm, preferably 20mm to 400mm, more preferably 100mm to 300mm.

The third link may transmit rotational motion between the first link and the second link at least one tilt angle, and in one example, at all tilt angles. The third link may be coupled to the first link and the second link, respectively, by respective joints that allow not only transmission of rotational movement but also tilting.

The delivery device further includes a first drive member coupled to the first drive shaft. The first drive member may be rotatable with the first drive shaft. The first drive member may be arranged on the first drive shaft or connected or attached to the first drive shaft. For example, the first drive member may be implemented as the second drive member. In some examples, the first drive member may be coupled with a drive motor for rotating the first drive shaft.

The first drive member may be an actuating component that engages with the second drive member. In other words, the first driving member may drive the second driving member and the second driving shaft. The first drive member may be coupled to the motor and transmit rotational motion from the motor for rotating the second drive shaft to the second drive member.

In some examples, one or both of the first and second drive members are or include, respectively, first and second gears, particularly first and second gears that rotate with respective drive shafts.

In some examples, the conveying device may include a drive motor. For example, the drive motor may be an electric motor. The drive motor may be connected to the first drive shaft. The first drive shaft may be connected to a drive gear of the drive motor. In another example, the drive motor may be coupled to the second drive shaft. For example, the second drive shaft may be connected to a drive gear of the drive motor.

The delivery device may further comprise a first frame. The first frame may carry or drive the first conveying section or a portion thereof. The first frame may comprise more than one rotatable part or member. In particular, the first frame may comprise a first drive shaft or a first drive member. Alternatively, the first frame may comprise one or more fixed parts or members that do not rotate, or one or more mounts or one or more bearings.

In addition, the conveying device may include a second frame. The second frame may carry or drive the second conveying section or a portion thereof. The second frame may be implemented as the first frame. In particular, the second frame may comprise or may consist of the second drive shaft or the second drive member.

In some examples, the second frame is disposed above the first frame. In addition, the second frame may be at least partially elevated. The first and second conveying portions may be disposed on the first and second frames, respectively.

In one example, the conveying device includes: a driving motor; a first frame including a first driving shaft connected to the driving motor and a first gear coupled to the first driving shaft and rotated together with the first driving shaft; a second frame including a second driving shaft and a second gear, the second frame being disposed above the first frame and partially movable in an up-down direction, the second gear being coupled to the second driving shaft and engaged with the first gear to transmit rotational power to the second driving shaft; and a conveying unit disposed on the first frame and the second frame, respectively. The second drive shaft may include: a first link coupled to the second gear; the second connecting rod is lifted relative to the first connecting rod; and a third link coupled to the first link and the second link, respectively, and rotating with respect to the first link and the second link as the second link moves up and down.

In one example, the delivery device further comprises a first mounting structure or a second mounting structure. For example, the first mounting structure may be configured such that the first frame or the first conveying portion is arranged on the first mounting structure, and the first frame or the first conveying portion may be mounted on the first mounting structure. For example, the second mounting structure may be configured such that the second frame or the second conveying portion is mounted on the second mounting structure by disposing the second frame or the second conveying portion on the second mounting structure. In some examples, one or both of the first and second mounting structures may be, or include, a plate. Accordingly, the first and second mounting structures may also be referred to as first and second plates, respectively.

The first mounting structure is rotatably coupled to the first frame. The first mounting structure may be non-rotatable, e.g. may be fixed at least along the rotational axis of the first drive shaft or the second drive shaft. In some examples, the first mounting structure may be fixed in all directions.

The second mounting structure may be disposed on the first mounting structure. The second mounting structure is rotatably coupled to the second frame. The second mounting structure may be non-rotatable, e.g. may be fixed at least along the rotational axis of the first drive shaft or the second drive shaft. The second mounting structure is movable relative to the first mounting structure along a first direction to adjust a spacing between the first conveying portion and the second conveying portion.

In some examples, the first mounting structure or a portion thereof and the first frame or a portion thereof may be implemented as a common structure or element. In some examples, the second mounting structure or a portion thereof and the second frame or a portion thereof may be implemented as a common structure or element.

In some examples, the conveyor further includes a support structure, e.g., that carries or retains at least a portion of the weight of the first conveyor to support the first conveyor. The support structure may support the first conveying part through the first mounting structure and/or the first frame. The support structure may include a support bracket for supporting the base portion and the first conveying portion. The support bracket can be rotatably coupled to the base portion by a hinge. The support bracket may be brought into contact with the first mounting structure and/or the first frame by rotating the support bracket relative to the base portion.

In some examples, the support bracket may have a distal end portion (e.g., a portion remote from a hinge that joins the support bracket to the base portion, e.g., a portion disposed at an opposite side end portion of the support bracket that is a hinge). The distal end portion may support the first conveying portion. The support bracket may be folded outwardly from the base portion by an external force. The support bracket may be refolded toward the base portion by an external force.

In one example, the conveying device may include a support portion that supports the first plate, and a support bracket rotatably coupled to the support portion and having one end supporting the first plate.

In one example, the support bracket may have an upper end capable of supporting the underside surface of the first plate. The support bracket is rotatable with respect to the support portion by an external force so as to be spaced apart from the first plate.

For example, the conveying device may further include a gap block interposed in a gap between the first conveying portion and the second conveying portion to separate the first conveying portion from the second conveying portion to a predetermined pitch or distance. The gap block may be interposed between the first mounting structure and the second mounting structure and/or between the first frame and the second frame. The predetermined distance may be determined by the thickness (or height) of the gap block.

In one example, the conveying device may include a gap block interposed in a gap between a first plate (e.g., one example of the first mounting structure) and a second plate (e.g., one example of the second mounting structure) to separate the gap between the first plate and the second plate to a set value.

In some examples, one or both of the first conveying section and the second conveying section may include a drive roller mounted on the first drive shaft and the second drive shaft, respectively. The drive shafts may rotate with each drive shaft. One or both of the first conveying portion and the second conveying portion may further include a conveyor belt wound around the driving roller, and the driving roller moves the conveyor belt by rotation of the driving roller. For example, the conveyor belt may advance the battery part in a direction of movement of the conveyor belt to move the battery part. Alternatively, the conveyor belt may seal the battery parts by applying heat or pressure to the battery parts, for example.

In some examples, one or both of the first conveying section and the second conveying section may include one or more tension rollers that apply tension or pressure to the conveyor belt. For example, the tension roller may be disposed on opposite sides of the drive roller. More than one tension roller may be arranged in contact with the conveyor belt. In some examples, more than one tension roller may apply tension to the conveyor belt by adjusting the length of the belt travel path to stretch the conveyor belt. Alternatively, more than one tension roller may apply pressure to the conveyor belt. The tension roller may adjust the tension or pressure applied to the conveyor belt. For this purpose, more than one tension roller can be moved vertically relative to the conveyor belt surface.

Alternatively, one or both of the first conveying section and the second conveying section may each include one or more idler rollers (e.g., a pair of idler rollers) around which the conveyor belt is wound. More than one idler roller may not be active, for example, may not be driven by a drive motor, but may be idle. Idler rollers may define a path of travel for the conveyor belt.

As an example, the conveying section may include: a driving roller mounted on the first driving shaft and the second driving shaft; a conveyor belt wound around the driving roller, and moved (e.g., rotated) by the rotation of the driving roller; a pair of tension rollers disposed on both sides of the pair of driving rollers, respectively, for applying tension or pressure to the conveyor belt; and a pair of idler rollers spaced apart from the tension roller and around which the conveyor belt is wound.

The conveying device may further include a tension adjusting portion capable of moving one or all of the plurality of tension rollers of the first conveying portion, or one or all of the plurality of tension rollers of the second conveying portion, to adjust tension or force on the conveyor belt to the respective conveying portions. For example, the tension adjusting portion may include or control an actuator for moving each tension roller.

In one example, the second plate (e.g., one example of the second mounting structure) may include a tension guide disposed on the conveyor belt and mounted with the tension roller in contact with the conveyor belt. The tension guide may include a tension adjusting part to move the tension roller up and down.

For example, the tension adjusting portion may be a tension adjusting cylinder that can move (e.g., move up/down/up/down) one or all of the respective tension rollers by air pressure or hydraulic pressure. Alternatively, the tension adjusting portion may be a lift adjusting device that can lift one or all of the plurality of tension rollers up and down by screw rotation. For example, the elevation adjustment means may move the respective tension rollers by rotating the nut member with respect to the screw member. In some examples, the tension adjusting portion may include two or more tension adjusting cylinders or two or more lifting adjusting devices.

For example, the idler roller adjusts the area of the linearly moving conveyor belt portion (linearly moving portion) by adjusting the length of the linearly moving conveyor belt portion. The linearly moving part may be a flat or planar part of the conveyor belt. In the linearly moving portion, the conveyor belt may move in a straight line. The portion may be disposed between idler rollers, for example, extending from a first idler roller to the other idler rollers of the plurality of idler rollers. The portion may be configured to be in contact with other conveying portions, in particular with the battery member facing the linear movement portion thereof. For example, the idler rollers may be moved to adjust the area of the linear moving object, thereby adjusting the spacing between the idler rollers.

The idler roller may be positioned in correspondence with the drive roller and the tension roller, for example perpendicular to the direction of movement of the conveyor belt. In other words, since the idler roller can be aligned with the drive roller and the tension roller in a direction perpendicular to the direction of belt movement, the path along which the belt extends or moves is placed in a plane perpendicular to the direction. The idler roller may be disposed spaced apart from the tension roller.

For example, as previously described, the conveying device may include a mounting structure for mounting the second conveying portion. The drive roller, the conveyor belt, the tension roller, and the idler roller of the second conveying section may be partially or entirely movable together when the mounting structure is moved. While each element may be rotatable relative to the mounting structure, it may be rotatably coupled to the mounting structure so as to move with the mounting structure as the mounting structure moves.

In one example, when the second plate (e.g., one example of the second mounting structure) moves upward, the drive roller, the conveyor belt, the tension roller, and the idler roller corresponding to the second drive shaft can move upward together.

In one example, the delivery device may further include a housing (or casing) for housing the first drive member (e.g., the first gear) or the second drive member (e.g., the second gear).

The delivery device may also include an extendable cylinder (e.g., a hydraulic or pneumatic extendable cylinder) to move the second delivery portion relative to the first delivery portion. In particular, the extendable cylinder may move the second transport section by moving the second transport section to move a second mounting structure (e.g., a second plate) mounted within or on the second mounting structure. The extendable cylinder may be a lifting cylinder, for example, an extendable cylinder that lifts and lowers the second conveying portion by lifting and lowering the second mounting structure.

In some examples, the extendable cylinder or a portion thereof may be mounted on the housing. The second conveying part can move relative to the housing. For example, the second mounting structure may be movable relative to the housing for moving the second conveying portion.

In one example, the conveying device includes a lift cylinder mounted on the housing and capable of moving the second plate up and down, and the second plate is movable up and down relative to the housing.

The axes or length directions of the first, second, and third links may be parallel to each other, and particularly, may be aligned in a straight line when the interval between the first and second conveying portions is a first value. In some examples, the structure may be an operational structure when the device is in normal use. For example, the conveying device may drive the first conveying portion and the second conveying portion by rotating the first or second driving shaft, and may be capable of sealing the battery part when a distance between the first conveying portion and the second conveying portion is at a first value. In one example, the first value is a minimum distance between the first conveying portion and the second conveying portion.

The third link may be inclined with respect to the first link and the second link when the interval between the first conveying portion and the second conveying portion is a second value. For example, its axis or length may be inclined with respect to the axis or length of the first and second links. In some examples, the structure may be a service provision or maintenance structure of the delivery device. For example, in a service providing and maintaining arrangement, the first and second transport sections or parts thereof may be accessible by a user or operator of the apparatus. The second value may be a maximum spacing between the first conveying portion and the second conveying portion.

In one example, the first link, the second link, and the third link may be arranged side by side in the same direction when the second driving shaft rotates. The third link may be configured to have its length direction inclined with respect to the length directions of the first link and the second link when the second driving shaft moves upward (e.g., when the second plate is lifted).

a first conveying section and a second conveying section;

a first driving shaft for driving the first conveying part, the first driving shaft being combined with a driving motor for rotating the first driving shaft;

A second drive shaft for driving the second conveying portion, the second drive shaft being partially moved relative to the first drive shaft to adjust a spacing between the first and second conveying portions; and

as the second link moves relative to the first link, the third link tilts relative to the first link and the second link.

The delivery device further includes a first drive member coupled to the first drive shaft, the first drive member being the actuation component that engages the second drive member.

Wherein the first and second drive members include first and second gears, respectively, that rotate with corresponding respective drive shafts.

Wherein, driving motor connects in first drive shaft.

The conveying device further includes:

a second frame including the second driving shaft,

the second frame is disposed above the first frame and is at least partially liftable, and the first conveying section and the second conveying section are disposed on the first frame and the second frame, respectively.

The conveyor further includes a support structure for supporting the first conveyor portion, the support structure including a support portion and a support bracket rotatably coupled to the support portion.

Wherein the support bracket has a distal end portion for supporting the first conveying portion, and is foldable from the support portion by an external force.

The conveying device further includes a gap block interposed in a gap between the first conveying portion and the second conveying portion to separate the first conveying portion and the second conveying portion by a predetermined distance.

Wherein the first conveying portion and the second conveying portion respectively include:

a driving roller mounted on the first driving shaft and the second driving shaft, respectively; and

A conveyor belt wound around the driving roller,

the driving roller moves the conveyor belt by rotating.

Wherein the first conveying portion and the second conveying portion respectively include: a pair of tension rollers disposed on opposite sides of the driving roller for applying pressure to the conveyor belt; and

and the idler rollers are used for winding the conveyor belt around.

The conveyor further includes a tension adjustment portion that moves the tension roller of the first conveyor portion or the second conveyor portion to adjust the tension on the conveyor belt of the respective conveyor portion.

The tension adjusting part is at least one of a tension adjusting cylinder for moving the corresponding tension roller through air pressure or hydraulic pressure or a lifting adjusting device for moving the corresponding tension roller through screw rotation.

Wherein the idler roller is used for adjusting the area of the linear movement part of the conveyor belt.

The conveying apparatus further includes a mounting structure for mounting the second conveying portion, and at least one of the driving roller, the conveyor belt, the tension roller, and the idler roller of the second conveying portion moves together when the mounting structure moves.

The conveying device further includes a lift cylinder that moves the second conveying portion relative to the first conveying portion.

Wherein the lifting cylinder is installed in the housing, and the second conveying part moves relative to the housing.

when the distance between the first conveying part and the second conveying part is a second value, the third link is inclined relative to the first link and the second link.

Effects of the utility model

In the conveying apparatus of the present utility model, even if a part of the apparatus such as the action part of the first driving member (e.g., the first gear) and the second driving member (e.g., the second gear) engaged with the action part are moved upward for replacement of the conveyor belt, the engagement can be maintained. That is, the contact state with each other can be maintained. Therefore, it is possible to avoid an impact between the action part (e.g., the first driving member) and the second driving member that may occur in the course of the action part and the second driving member being separated from each other and being contacted again. Therefore, the action part and the second driving member can be effectively suppressed from being worn or damaged by the impact.

In addition, a separate operation for separating and then re-coupling the operation member and the second driving member is not required. Therefore, the replacement time of the conveyor belt can be significantly shortened.

Accordingly, durability of the conveying device can be improved, and time and effort required for replacement of the conveyor belt can be significantly reduced.

In addition, in the conveying device of the present utility model, the gap block can be used to adjust the spacing between the first conveying portion and the second conveying portion (for example, between the first mounting structure such as the first plate and the second mounting structure such as the second plate), so that the spacing between the pair of conveyor belts can be easily adjusted.

In addition, in the conveying apparatus of the present utility model, the user can rotate the support bracket with respect to the base portion of the support structure such as the support portion by simply applying an external force to bring the support bracket into contact with the first mounting structure (for example, the first plate) or separating the support bracket from the first mounting structure.

Therefore, due to the structure of the support bracket, it is unnecessary to disassemble or reassemble the coupling mechanism for coupling the support bracket and the first mounting structure at the time of replacing the conveyor belt, and thus the work efficiency of replacing the conveyor belt can be improved.

Specific matters for carrying out the present utility model will be described below, together with the effects described above and specific effects of the present utility model.

Fig. 3 is a perspective view showing a conveying apparatus for sealing a battery or a battery part according to an embodiment of the present utility model. The illustration of the conveyor belt 420 in fig. 3 is omitted for the sake of more clarity.

First, a conveyor for sealing a battery or a battery part according to an embodiment of the present utility model will be described with reference to fig. 3, and next, problems of a conventional (e.g., conventional) conveyor will be described with reference to fig. 1 and 2.

For example, the delivery device for sealing a battery or battery part of the present utility model may be used to seal electrode portions of a battery or battery part by applying pressure to the battery or battery part and heating the battery or battery part. Hereinafter, for the sake of brevity, only the term "battery part" is used in reference to the battery or battery part. Thus, the term "battery component" should be understood to include not only batteries, but also battery components such as battery cells.

In the example of fig. 3, the apparatus may include a driving motor 100, a first frame 200, a second frame 300, and a conveying part 400. Accordingly, the device may be referred to as a delivery device hereinafter.

The driving motor 100 may provide a driving force for driving the conveying part. The conveying section 400 includes a first conveying section and a second conveying section, each of which includes each conveyor belt 420 (not shown in fig. 3). The conveying section 400 is operated by the operation of the driving motor 100. The battery part interposed between the pair of the conveyor belts 420 may be moved by the pair of conveyor belts 420 and pressurized, thereby being sealed.

The battery components may be pressurized by a pair of conveyor belts 420. The transport device may further include other heating means for heating the battery member for sealing.

The first frame 200 may carry or drive the first conveying portion. The first frame 200 may include a first driving shaft 210 connected to the driving motor 100 and a first gear 220 coupled to the first driving shaft 210 as a first driving member and rotated together with the first driving shaft 210. The first frame 200 is directly connected to the driving motor 100 to receive a driving force from the driving motor 100, for example, a torque generated by the driving motor 100 to rotate.

The second frame 300 may carry or drive the second conveying portion. In the example of fig. 3, the second frame 300 is disposed above the first frame 200 and includes a vertically movable (i.e., partially liftable) portion. The second frame 300 may include a second driving shaft 310 and a second gear 320 coupled to the second driving shaft 310 as a second driving member. The second gear 320 transmits a rotational motion (e.g., torque or rotational force) to the second driving shaft 310 by meshing with the operating portion coupled to the driving motor 100, i.e., the first gear 220 in the example of fig. 3.

The second gear 320 of the second frame 300 may be engaged with the first gear 220 in the first frame 200. Accordingly, the second frame 300 may be driven by receiving the driving force from the first frame 200.

On the first frame 200 and the second frame 300, a conveyor belt 420 may be installed, respectively. A pair of conveyor belts 420 mounted on the first and

second frames

200 and 300 are arranged to be spaced apart (e.g., vertically spaced apart) from each other. Accordingly, a gap or separation space may be formed between the pair of conveyor belts 420.

The battery part may be disposed in the separation space. The battery parts may be sealed while being moved along the conveyor belt 420. Since the conveyor belt 420 may be worn or damaged during repeated sealing operations, it may be necessary to periodically replace a pair of conveyor belts 420.

To replace the conveyor belts 420, it may be necessary to increase the spacing (e.g., separation distance) between a pair of conveyor belts 420 (e.g., between the linear movement portions thereof). A portion of the second frame 300 may move up and down. Accordingly, when the conveyor belts 420 are replaced, or in order to provide other service or maintenance work, a portion of the first frame 200 may be moved upward, so that the separation distance between the conveyor belts 420 can be increased.

As described above, in case that the separation distance between the pair of conveyor belts 420 is increased, the conveyor belt 420 is inserted into the conveyor apparatus after the conveyor belt 420 is withdrawn from the conveyor apparatus through a gap (e.g., a vertical gap) between the first frame 200 and the second frame 300, so that the conveyor belt 420 can be replaced.

The conveying section 400 may be disposed on the first frame 200 or the second frame 300, respectively. Accordingly, a pair of conveying portions 400 may be disposed on the first frame 200 and the second frame 300, respectively. Accordingly, a pair of conveying parts 400 (i.e., first and second conveying parts) respectively disposed at the first frame 200 and the second frame 300 are provided. In some embodiments, the pair of delivery portions 400 have shapes that are symmetrical to each other, and may be disposed in symmetrical positions. The pair of delivery portions 400 may be mirror symmetrical with respect to a plane in which the battery parts are to be disposed or moved.

Each transport section 400 may include a drive roller 410, a conveyor belt 420, a tension roller 430, and an idler roller 440.

The driving roller 410 may be mounted on the first and

second frames

200 and 300, i.e., the first and

second driving shafts

210 and 310, respectively. The driving roller 410 is mounted on the driving shaft to move or rotate the conveyor belt 420 wound therearound. A pair of driving rollers 410 respectively mounted on the respective first and

second driving shafts

210 and 310 may be provided.

The conveyor belt 420 may be moved by the rotation of the driving roller 410. The tension roller 430 and the idler roller 440 may be rotated by the rotation of the conveyor belt 420. For example, the tension roller 430 and the idler roller 440 may idle.

The conveyor belt 420 (refer to fig. 5) may be wound around the driving roller 410 and may be moved by the rotation of the driving roller 410. As described previously, the battery part may be interposed between the pair of the conveyor belts 420, and the battery part may be sealed while being moved along the conveyor belts 420 as the conveyor belts 420 rotate.

A pair of tension rollers 430, respectively disposed on both sides of the driving roller 410, may be provided, and such tension rollers may apply tension or pressure to the conveyor belt 420. The pair of tension rollers 430 may be disposed at the first driving shaft 210 and the second driving shaft 310, respectively. That is, the first and second conveying parts may include a pair of tension rollers 430, respectively. Thus, two pairs of tension rollers 430, i.e., a total of four tension rollers 430, may be provided.

The tension roller 430 can apply tension or pressure to the conveyor belt 420 by pressing or pushing the conveyor belt 420 in a direction intersecting (e.g., perpendicular) to the direction of movement of the conveyor belt 420, in the example of fig. 3, in a substantially perpendicular direction. The tension of the conveyor belt 420 is regulated by the tension roller 430, and the conveyor belt 420 can effectively apply pressure to the battery parts, thereby performing a sealing operation. The tension roller 430 may contact the conveyor belt 420 and be rotated by the movement of the conveyor belt 420.

A pair of idler rollers 440 may be provided spaced from the tension roller 430. The conveyor belt 420 may be wound around a pair of idler rollers 440. The pair of idler rollers 440 may be disposed at the first driving shaft 210 and the second driving shaft 310, respectively. That is, the first conveying part and the second conveying part may include a pair of idler rollers 440, respectively. Thus, two pairs of idler rollers 440, i.e., a total of four idler rollers 440, may be provided.

Idler roller 440 is included in the conveyor, and can adjust the area and length of the linear moving portion (linear moving portion) of belt 420 that rotates in the shape of a track. For example, the linear motion may be a flat portion or a planar portion of the conveyor belt 420. In the linear moving part, the conveyor belt 420 may move or advance in a straight line. The conveyor belt 420 may be wound around an idler roller 440. As the conveyor belt 420 rotates, the idler roller 440 may be rotated by movement of the conveyor belt 420.

As shown in fig. 3, the idler roller 440 may be disposed at a position corresponding to the driving shaft 410 and the tension roller 430 in a direction perpendicular to the moving direction of the conveyor belt 420. Idler roller 440 may be spaced apart from tension roller 430. Thus, the conveyor belt 420 may linearly move at a portion between the idle rollers 440 spaced apart from each other in the horizontal direction.

In addition, the conveyor belt 420 may be wound around the idler roller 440 at a portion contacting the idler roller 440 and bent. Accordingly, with the change of the moving direction, the conveyor belt 420 may again perform linear movement at the portion of the conveyor belt 420 that moves in the direction opposite to the direction in which the battery part is moved by the conveyor belt 420.

The conveying device may further include: a first mounting structure for mounting the first frame 200 and the first conveying part; and a second mounting structure for mounting the second frame 300 and the second conveying part. In the example of fig. 3, the first mounting structure is a first plate 500 and the second mounting structure is a second plate 600. The first frame 200 may be rotatably coupled to the first plate 500 such that the first frame 200 or a portion thereof is free to rotate in a state where the first plate 500 is stopped. As shown in fig. 3, the second plate 600 may be disposed on the first plate 500. The second frame 300 may be rotatably coupled to the second plate 600 such that the second frame 300 or a portion thereof is free to rotate in a state where the second plate 600 is stopped.

The second plate 600 may also move up and down as the second frame 300 moves up and down. The spacing or separation distance 1000 (e.g., vertical separation distance) between the first plate 500 and the second plate 600 may be shorter than the spacing or separation distance between the pair of conveyor belts 420.

When the conveyor belt 420 is replaced, a part of the conveyor apparatus is disassembled, the second plate 600 is moved upward, and the conveyor belt 420 is replaced, so that the vertical separation distance 1000 between the first plate 500 and the second plate 600 can be increased, and the vertical separation distance 1000 of the pair of conveyor belts 420 can be increased. The first plate 500 (i.e., the frame 200 and the first conveying part) may be fixed, i.e., may not move.

Referring to fig. 1 and 2, in a general (e.g., conventional) conveyor, when the second frame 300 is raised in order to replace the conveyor belt 420, the entire second frame 300 constituting the upper portion of the conveyor, the conveyor 400 mounted on the second frame 300, and the second plate 600 mounted with the second frame 300 are raised together. Accordingly, the second driving shaft 310 mounted on or forming the second frame 300 also rises together with the second gear 320.

At this time, the second gear 320 is lifted up together with the lifting of the second frame 300 from the state of being engaged with the first gear 220, thereby being spaced apart from the first gear 220.

After the replacement of the conveyor belt 420, when the second frame 300 descends again, the second gear 320 may descend and contact the first gear 220 again. At this time, when the first gear 220 and the second gear 320 contact each other, the first gear 220 and the second gear 320 may collide or collide with each other.

In addition, when the second gear 320 descends and contacts the first gear 220, the first gear 220 and the second gear 320 may not be smoothly engaged to enable the second gear 320 to rotate by receiving the driving force transmitted from the first gear 220.

Therefore, a separate operation of meshing the first gear 220 with the second gear 320 is required to interlock them and smoothly rotate.

Finally, when the first gear 220 and the second gear 320 in the engaged state are spaced apart from each other (e.g., vertically separated) in order to replace the conveyor belt 420, when the first gear 220 and the second gear 320 are engaged again after the conveyor belt 420 is replaced, abrasion or damage due to impact may occur between the first gear 220 and the second gear 320, thereby reducing the durability of the conveying apparatus.

In addition, since a separate operation of meshing between the first gear 220 and the second gear 320 is required, time and cost in the sealing operation may increase. Accordingly, in the present utility model, a structure capable of solving at least a part thereof is proposed. Hereinafter, this will be specifically described with reference to the drawings.

Fig. 4 is a top view showing a part of a conveying apparatus of an embodiment of the present utility model. Fig. 5 is a side cross-sectional view showing a part of a conveying apparatus of an embodiment of the present utility model.

In the conveying apparatus of an embodiment of the present utility model, a universal joint structure may be provided on the second driving shaft 310. The universal joint structure may move another portion of the second drive shaft adjacent to or in contact with the second conveying portion in a state in which a portion of the second drive shaft is stopped (i.e., other portion of the second drive shaft is not moved). For example, the second driving shaft 310 may include a first link 311, a second link 312, and a third link 313. The first link 311, the second link 312, and the third link 313 may be connected to each other as a universal joint structure. For example, the gimbal structure may allow movement of the second link 312 without moving the first link 311.

The first link 311 may be coupled with the second gear 320. Accordingly, since the second gear 320 is fixedly coupled to the first link 311, the first link 311 may be rotated by receiving the driving force from the first gear 220.

For example, the second link 312 may move up and down with respect to the first link 311 to adjust the interval between the first and second conveying parts. For example, the second link 312 can be rotatably coupled to the second plate 600, and thus, the second link 312 can freely rotate with respect to the second plate 600. When the second frame 300 and the second plate 600 move up and down, the second link 312 may move up and down together with the second frame 300 and the second driving roller 410. The second driving roller 410 may be supported by the second link 312.

Both ends of the third link 313 may be coupled with the first link 311 and the second link 312, respectively. As the second link 312 moves up and down, the third link 313 may be inclined with respect to the first link 311 and the second link 312. For example, both ends of the third link 313 may be hinged to respective ends of the first link 311 and the second link 312 by respective universal joints. Accordingly, as the second link 312 moves up and down, the third link 313 may be inclined with respect to the first link 311 and the second link 312.

Fig. 6 is a diagram illustrating a portion of the second driving shaft 310 according to an embodiment of the present utility model. Fig. 7 is a view showing a state in which the second driving shaft 310 is lifted from the second link 312 shown in fig. 6.

Fig. 6 is a view showing a state of the configuration of the second driving shaft 310 when the conveying device is operated to seal the battery part. Fig. 7 is a view showing a state of arrangement of the second driving shaft 310 when the second plate 600 is lifted for replacement of the conveyor belt 420.

In the state shown in fig. 6, the second driving shaft 310 may rotate with its length direction as the rotation axis direction. That is, the length direction of the second driving shaft 310 may correspond or coincide with the rotation axis. When the second driving shaft 310 rotates, the first, second and

third links

311, 312 and 313 may be parallel to each other and aligned in a straight line.

In the state shown in fig. 7, that is, in the state in which the conveyor belt 420 is replaced, the second driving shaft 310 is not rotated, and the second link 312 may be lifted, at which time the second plate 600 may be lifted. Accordingly, the third link 313 may be inclined with respect to the first connection 311 and the second link 312 in this structure. In some examples, the joint or hinge that couples the third link 313 to the first link 311 and the second link 312 may be a universal joint that allows the second drive shaft 310 to rotate when the third link 313 is tilted. For example, the

links

311, 312, 313 may be rotated centering on the respective axes or longitudinal directions.

When the second plate 600 is lifted, the driving roller 410, the conveyor belt 420, the tension roller 430, and the idler roller 440 corresponding to the second driving shaft 310 may be lifted together.

That is, when the second plate 600 is lifted, at least a portion of the second frame 300 and the second conveying part, particularly the second link 312, the driving roller 410 mounted on the second link 312, and the conveyor belt 420 wound around the driving roller 410 may be moved upward.

When the second plate 600 is lifted, the third link 313 may be configured to be inclined with respect to the length direction of the first link 311 and the second link. As shown in fig. 6 and 7, the second link 312 may be shifted in parallel, i.e., the second link 312 may be shifted in a state of not being inclined. As shown in fig. 6 and 7, the third connection 313 may rotate centering on a hinge coupling the third connection 313 to the first connection 311. In some examples, the third link 313 may be elongated, e.g., the length of the third link may be increased. This may allow preventing the second link 312 from moving along its axis when the third link 313 is tilted.

That is, as shown in fig. 5, when the second plate 600 is lifted, the second link 312 and the third link 313 move, but the first link 311 does not move. Accordingly, the second gear 320 mounted to the first link 311 may not move, but remain engaged with the first gear 220 mounted to the first frame 200.

Due to this structure, even when a part of the conveyor is lifted to replace the conveyor belt 420, the first gear 220 and the second gear 320 can be kept engaged. Accordingly, the impact between the first gear 220 and the second gear 320, which occurs in the process of separating and re-contacting the first gear 220 and the second gear 320 from each other, is avoided. Accordingly, the abrasion of the first gear 220 and the second gear 320 due to the impact can be effectively suppressed.

In addition, a separate work is not required to separate the first gear 220 from the second gear 320 and then re-mesh. Accordingly, the replacement time of the conveyor belt 420 can be significantly reduced.

Accordingly, durability of the conveying device is improved, and time and effort for replacing the conveyor belt 420 can be significantly reduced.

Hereinafter, an additional structure of the conveying apparatus according to an embodiment of the present utility model will be specifically described. The delivery device of an embodiment may further comprise a tension guide 610.

The tension guide 610 may be disposed on, or as part of, the second plate 600 in this example, in the second mounting structure. The tension guide 610 may be disposed on the conveyor belt 420. The tension guide 610 may be configured such that the tension roller 430 is in contact with the conveyor belt 420.

The tension guide 610 may be combined with the second plate 600, for example, stuck or formed as one body. The tension guide 600 may have a member disposed on the second plate 600, for example, extending toward the second conveying portion. The tension roller 430 may be coupled to the tension guide 610 in contact with the conveyor belt 420. For example, the tension guide 610 may include a tension adjusting part 611 that moves the tension roller 430 up and down to adjust tension or pressure applied to the conveyor belt 420.

When the tension adjusting part 611 moves the tension roller 430 downward, the tension roller 430 may apply pressure to the conveyor belt 420 to increase the tension or force of the conveyor belt 420. Conversely, when the tension adjusting part 611 moves the tension roller 430 upward, the tension roller may apply pressure or reduce force to the conveyor belt 420, thereby reducing the tension or force of the conveyor belt 420.

The tension roller 430 is moved up and down to adjust the tension or force of the conveyor belt 420, so that the pressure applied to the battery part sealed by the conveyor belt 420 can be appropriately adjusted.

In this example, since the pair of tension rollers 430 is provided corresponding to the second frame 300, the pair of tension guides 610 may be provided corresponding to each other, and the pair of tension adjusting portions 611 disposed on the respective tension guides 610 may be provided.

The tension adjusting portion 611 may be at least one of a tension adjusting cylinder 6111 for moving the tension roller 430 up and down by pneumatic pressure or hydraulic pressure, and a lift adjusting device 6112 for moving the tension roller 430 up and down by screw rotation.

In the example shown in fig. 3, a tension adjusting cylinder 6111 is provided in one tension guide 610, and a lifting adjusting device 6112 is provided in the other tension guide 610. In another example, the tensioning cylinder 6111 may be provided across the pair of tensioning guides 610, or the elevation adjustment means 6112 may be provided across the pair of tensioning guides 610.

The delivery device of an embodiment of the present utility model may further comprise a housing 920 and an extendable cylinder, such as a lift cylinder 930.

The housing 920 may house the first gear 220 and the second gear 320 inside. The case 920 may be in a box shape with an opened upper surface, and may accommodate the first gear 220 and the second gear 320.

The lift cylinder 930 may be mounted to the housing 920. The lifting cylinder 930 may lift the second plate 600. For example, the lift cylinder 930 may be operated by air pressure or hydraulic pressure. When the second plate 600 is lifted by the lifting cylinder 930, as described above, the first link 311 of the second driving shaft 310 and the second gear 320 mounted to the first link 311 do not move, and thus, even when the conveyor belt 420 is replaced, the first gear 220 and the second gear 320 can be maintained in a state of being engaged with each other.

The second plate 600 may move up and down with respect to the housing 920. The housing 920 may maintain a position without moving even when the second plate 600 is lifted and lowered. That is, even when the second plate 600 is lifted, the housing 920 accommodating the first gear 220 and the second gear 320 does not move, and thus, the first gear 220 and the second gear 320 may be maintained in a state of being engaged with each other. For example, the housing 920 may be fixed to the first plate 500.

Fig. 8 is a perspective view showing a part of a conveying apparatus according to an embodiment of the present utility model. Fig. 9 is a perspective view of the conveyor of fig. 8 showing a folded state of the support bracket.

The conveying apparatus of an embodiment of the present utility model may further include a gap block 910. The gap block 910 may be inserted into a gap between the first plate 500 and the second plate 600. The gap block 910 may separate the first plate 500 from the second plate 600 to a predetermined distance.

The "slits" may refer to a vertically spaced space between the first plate 500 and the second plate 600 and a space between the first conveying part and the second conveying part, respectively, in a state in which the conveying device performs a battery part sealing operation.

A plurality of gap blocks 910 may be provided. Each of the gap blocks 910 may be inserted into a gap between the first plate 500 and the second plate 600 by a user, or each of the gap blocks 910 may be removed from the gap. As the gap between the first plate 500 and the second plate 600 increases, the interval between the pair of conveyor belts 420, i.e., the vertical separation distance, may be increased.

The size and thickness of the battery components running on the conveyor may vary. Therefore, in order to seal various forms of battery parts different in size and thickness in the same conveying apparatus, it may be necessary to adjust the interval (e.g., vertical separation distance) between the pair of conveyor belts 420.

In this example, the spacing between the pair of conveyor belts 420 may be adjusted by adjusting the size of the gap.

The gap block 910 may be inserted in a gap between the first plate 500 and the second plate 600. The gap blocks 910 may have different heights or thicknesses from each other. Accordingly, gap blocks 910 of various thicknesses may be inserted into gaps between the first plate 500 and the second plate 600 to adjust the size of the gaps.

The thickness of the gap block 910 may be 5mm to 50mm, preferably 10mm to 20mm, more preferably 10mm, 15mm, 20mm, etc. The user may insert the gap block 910 having a corresponding thickness into the gap in consideration of the size and thickness of the battery part, thereby setting the gap between the first plate 500 and the second plate 600 to a set value.

Thus, the pair of conveyor belts 420 may be maintained in a spaced apart state with a gap therebetween having a value set according to different battery parts.

In this instance, the gap block 910 may be used to adjust the spacing between the first plate 500 and the second plate 600, and thus the spacing between the pair of conveyor belts 420 may be easily adjusted.

The transfer device of an embodiment of the present utility model may further include a support structure capable of supporting the first conveying portion. The support structure may include a base portion, for example, a support portion 700 and a support bracket 800. For example, the support part 700 may support the first plate 500 so as to carry at least a portion of the weight of the first plate 500 and the first conveying part. The lower end of the support 700 may be placed on a building structure such as the floor of an installation site of the conveyor.

The support bracket 800 may be disposed at an upper portion of the support part 700. The support bracket 800 may be rotatably coupled to the support 700. The end portion of the support bracket 800 may support the first plate 500. Since the support bracket 800 and the support part 700 may be hinged by the rotation pin 810, the support bracket 800 may be folded back toward the support part 700 after being folded outward from the support part 700.

The support part 700 and the support bracket 800 can stably support the first plate 500 and the second plate 600 positioned at the upper portion of the first plate 500 through one or more gap blocks 910. The supporting part 700 and the supporting bracket 800 can horizontally configure the conveying device (to horizontally level the first plate 500 and the second plate 600).

The support bracket 800 may support the first plate 500 when the conveyor seals the battery part. In order to replace the conveyor belt 420 located at the first driving roller 210 mounted on the first plate 500, it may be necessary to separate the support bracket 800 from the first plate 500. This is because the support bracket 800 becomes an obstacle when mounting the conveyor belt 420 to the first driving shaft 210 or removing the conveyor belt 420 from the first driving shaft.

Therefore, for example, when the conveyor belt 420 is replaced, a structure capable of easily separating the support bracket 800 from the first plate 500 is required. Accordingly, in the conveying apparatus of an embodiment of the present utility model, the support bracket 800 may have a distal end portion (e.g., an upper end configured to be opposite or opposite to the rotation pin 810) to support the first plate 500, for example, a lower side surface of the first plate 500. The support bracket 800 may be rotated with respect to the support part 700 by an external force so as to be separated or spaced apart from the first plate 500.

The end portion of the support bracket 800 may support the lower side surface of the first plate 500. Other coupling means for coupling the support bracket 800 with the first plate 500 may not be provided. By applying an external force to rotate the support bracket 800 to the support part 700, an operator can easily separate the support bracket 800 from the first plate 500.

The fastening strength of the rotation pins 810 is appropriately adjusted to prevent the support bracket 800 from rotating due to a relatively weak external force, so that it is possible to suppress the occurrence of an accident in which the support bracket 800 rotates due to an external impact and is separated from the first plate 500 at the time of the sealing operation. For example, the force required for rotation of the support bracket 800 may be adjusted by adjusting the fastening strength of the rotation pin 810.

After replacing the conveyor belt 420, the user may apply an external force again to cause the upper end of the support bracket 800 to support the lower side surface of the first plate 500, thereby rotating the support bracket 800 with respect to the support part 700.

In this example, the support bracket 800 and the first plate 500 may contact each other without other coupling tools, and even in such a structure, the support bracket 800 may support the first plate 500.

After replacing the conveyor belt 420, the user may rotate the support bracket 800 with respect to the support part 700 by simply applying an external force, and may contact the support bracket 800 with the first plate 500 or separate the support bracket 800 and the first plate 500 from each other.

Therefore, due to the structure of the support bracket 800, when the conveyor belt 420 is replaced, a coupling tool that can couple the support bracket 800 with the first plate 500 does not need to be disassembled or reassembled, and thus the efficiency of the replacement operation of the conveyor belt 420 can be improved.

In view of the above, it will be appreciated that the present utility model also relates to the following examples.

An example delivery device may include: a driving motor; a first frame including a first driving shaft connected to the driving motor and a first gear (e.g., an example of a first driving member) coupled to the first driving shaft and rotated together with the first driving shaft; a second frame including a second driving shaft and a second gear (for example, an example of a second driving member) disposed at the first frame and partially moving up and down, the second gear being coupled to the second driving shaft to transmit rotational power to the second driving shaft and engaged with the first gear; and a conveying section disposed on the first frame and the second frame, respectively, wherein the second driving shaft may include: a first link coupled with a second gear; a second link that moves up and down with respect to the first link; and a third link coupled to the first link and the second link, respectively, and rotating with respect to the first link and the second link as the second link moves up and down.

The example conveying device may further include a first plate (e.g., an example of the first mounting structure) rotatably coupled to the first frame, and a second plate (e.g., an example of the second mounting structure) disposed on the first plate and rotatably coupled to the second frame.

The transport device according to one example further includes: a support portion (e.g., a support portion) capable of supporting the first plate; and a support bracket rotatably coupled to the support portion and having one end supporting the first plate.

One example of the conveying device may further include a gap block inserted in a gap between the first plate and the second plate to separate a distance between the first plate and the second plate to a set value.

The conveying section may include: a driving roller mounted on the first driving shaft and the second driving shaft; a conveyor belt wound around the driving roller and rotated by the rotation of the driving roller; a pair of tension rollers disposed on both sides of the driving roller, respectively, and applying pressure to the conveyor belt; and a pair of idler rollers spaced apart from the tension roller and wound with a conveyor belt.

In one example of the conveying device, the second plate may further include a tension guide provided on the conveyor belt and to which the tension roller is attached so as to be in contact with the conveyor belt, and the tension guide may include a tension adjusting portion capable of moving the tension roller up and down.

The tension adjusting unit may be at least one of a tension adjusting cylinder capable of moving the tension roller up and down by air pressure or hydraulic pressure, and a lifting adjusting device capable of moving the tension roller up and down by a screw rotation method.

The idler roller may be disposed at a position corresponding to the driving roller and the tension roller in a direction in which the conveyor belt moves, and may be disposed apart from the tension roller.

The conveyor of one example may further include a housing accommodating the first gear and the second gear, and a lift cylinder mounted to the housing and moving the second plate up and down, wherein the second plate is movable up and down with respect to the housing.

The first link, the second link, and the third link may be arranged side by side in the same direction when the second driving shaft rotates, and the third link may be configured to have a length direction inclined with respect to the length directions of the first link and the second link when the second driving shaft moves upward (e.g., when the second plate rises).

The support bracket may have an upper portion to support an underside surface of the first plate. The support bracket may be rotated with respect to the support part by an external force so as to be spaced apart from the first plate.

When the second plate moves upward, the driving roller, the conveyor belt, the tension roller, and the idler roller corresponding to the second driving shaft may move upward together.

The features, elements, and/or functions of the above-listed examples may be combined, integrated, and/or substituted for the features, elements, and/or functions of any of the other examples described herein, and vice versa, where technically possible.
