Referring toFIGS.6and7, the mattress edge sewing apparatus having a rotation driving part according to an embodiment of the present disclosure includes a frame1110, a processing part1120, a first shaft1131, a second shaft1132, a third shaft1133, and a conveyor belt1140.

The frame1110may be formed in a rectangular plate shape, may be a work bench on which the mattress10is placed, and may be formed of a frame in which a plate is installed on an upper portion thereof so that edges of the mattress10are processed.

The processing part1120is disposed on a side surface of the frame1110, and may process the edges of the mattress10. The processing part1120may be a device capable of sewing the edges of the mattress10. However, the processing part1120is not limited thereto, and the processing part1120may include various devices as long as they are devices capable of processing the edges of the mattress10. The edges of the mattress10may be processed while passing through the processing part1120. The mattress10is formed in a rectangular shape. One edge of the mattress10passes through the processing part1120, and then, the mattress10is rotated and the other edge of the mattress10is processed.

A conventional mattress processing apparatus does not have a configuration capable of rotating the mattress. Since the mattress has a large volume and a significant weight, through the conventional mattress processing apparatus, it is difficult to process the mattress while rotating the mattress.

In order to solve this problem, in the mattress edge sewing apparatus having a rotation driving part according to an embodiment of the present disclosure, the frame1110may be divided into a plurality of frames through the first shaft1131, the second shaft1132, and the third shaft1133, and a rotation driving part1150may rotate the mattress while controlling a moving direction of the conveyor belt1140provided in the frame1110.

Referring toFIG.6, the first shaft1131divides the frame1110into frames while extending in a longitudinal direction. The first shaft1131vertically divides the frame1110into one side and the other side of the frame1110.

Here, the longitudinal direction may be a vertical direction (inFIG.6, a width direction in which the frame1110extends short) with respect toFIG.6, and a transverse direction may be a horizontal direction (inFIG.6, a width direction in which the frame1110extends long) with respect toFIG.6. In addition, with respect toFIG.6, one side of the frame1110may be a side of the first shaft1131in a rightward direction, and the other side of the frame1110may be a side of the first shaft1131in a leftward direction.

The second shaft1132divides one side of the frame1110, which is obtained by dividing frame1110through the first shaft1131, while extending in the transverse direction. The third shaft1133divides the other side of the frame1110, which is obtained by dividing the frame1110through the first shaft1131, while extending in the transverse direction.

That is, the second shaft1132horizontally divides one side of the frame1110, which is obtained by dividing the frame1110through the first shaft1131, and the third shaft1133horizontally divides the other side of the frame1110, which is obtained by dividing the frame1110through the first shaft1131.

Here, the second shaft1132and the third shaft1133may not be disposed on the same line. Referring toFIG.6, one side and the other side of the frame1110may be divided such that the second shaft1132and the third shaft1133are not disposed on a single horizontal line.

Specifically, the second shaft1132may horizontally divide one side of the frame1110, which is obtained by dividing the frame1110through the first shaft1131, equally, and the third shaft1133may horizontally divide the other side of the frame1110, which is obtained by dividing the frame1110through the first shaft1131, unequally.

The mattress10may be moved while being placed on the frame1110, and one side of the frame1110may be used as a point at which the mattress10is moved in the transverse direction, and thus the second shaft1132may horizontally divide one side of the frame1110into frames with equal areas.

In addition, as will be described below, since the other side of the frame1110may be used as a point at which the mattress10is rotated, the third shaft1133preferably horizontally divides the other side of the frame1110into frames with unequal areas.

The conveyor belt1140is provided in each of the divided frames1110, and may move in a direction parallel to the transverse direction. The mattress10may be moved or rotated by the movement of the conveyor belt1140provided in the frame1110, and the conveyor belt1140provided in each of the divided frames1110may be moved independently.

Specifically, the frame1110may be divided into a first frame1111, a second frame1112, a third frame1113, and a fourth frame1114, and the conveyor belt1140may include a first conveyor belt1141, a second conveyor belt1142, a third conveyor belt1143, and a fourth conveyor belt1144.

Referring toFIGS.6and7, the first frame1111is disposed on one side of the first shaft1131and on an upper side of the second shaft1132, and the second frame1112is disposed on the other side of the first shaft1131and on an upper side of the third shaft1133.

The third frame1113is disposed on the other side of the first shaft1131and on a lower side of the third shaft1133, and the fourth frame1114is disposed on one side of the first shaft1131and on a lower side the second shaft1132.

The first conveyor belt1141may be provided in the first frame1111and may move forward or backward in a direction parallel to the transverse direction, and the second conveyor belt1142may be provided in the second frame1112and may move forward or backward in a direction parallel to the transverse direction.

The third conveyor belt1143is provided in the third frame1113and may move forward or backward in a direction parallel to the transverse direction, and the fourth conveyor belt1144is provided in the fourth frame1114and may move forward or backward in a direction parallel to the transverse direction.

The mattress edge sewing apparatus having a rotation driving part according to an embodiment of the present disclosure may further include the rotation driving part1150that is formed in a bar shape and capable of rotating the mattress10.

The rotation driving part1150is formed in a bar shape and may rotate, and is installed on the side surface of the frame1110and may rotate toward the inside of the frame1110.

Referring toFIG.8, as one side of the rotation driving part1150is coupled to a side portion of the frame1110, the other side of the rotation driving part1150may rotate around the one side in a direction from the side portion of the frame1110toward the inside of the frame1110.

Specifically, the rotation driving part1150may be installed on a side surface of the second frame1112. One side of the rotation driving part1150is installed in the second frame1112at a point close to the first shaft1131and extends along the side surface of the second frame1112.

The rotation driving part1150may rotate around one side thereof, and the rotation driving part1150may sweep an upper portion of the second frame1112while rotating.

The mattress10moved to the second frame1112may rotate by the operation of the rotation driving part1150. Specifically, the edge of the mattress10, which is processed through the processing part1120, is brought into contact with the rotation driving part1150while being moved to the second frame1112. When the rotation driving part1150rotates, the mattress10in contact with the rotation driving part1150rotates while being pushed.

Referring toFIG.9, the mattress edge sewing apparatus having a rotation driving part according to an embodiment of the present disclosure may further include a driving part1160.

The driving part1160is provided on an upper portion of the rotation driving part1150and may rotate together with the rotation driving part1150while being raisable and lowerable with respect to the rotation driving part1150.

The driving part1160fixes the mattress10when rotating the mattress10through the rotation driving part1150. When the mattress10is not fixed when the mattress10is rotated by the rotation driving part1150, there is a risk that the mattress10is not rotated in a target direction while being separated from the rotation driving part1150.

The driving part1160is provided to prevent such a phenomenon, and the driving part1160may be formed in a bar shape or a rod shape. The driving part1160fixes an upper surface of the mattress10while moving downward before the rotation driving part1150rotates.

The driving part1160may rotate together with the rotation driving part1150, and when the mattress10is fixed through the driving part1160, the mattress10may be rotated while being prevented from being separated from the rotation driving part1150.

The mattress edge sewing apparatus having a rotation driving part according to an embodiment of the present disclosure may further include a control part capable of controlling the movement of the conveyor belt1140. The control part may control the movement of each of the first conveyor belt1141, the second conveyor belt1142, the third conveyor belt1143, and the fourth conveyor belt1144.

Referring toFIG.10, when the mattress10placed on the second frame1112is rotated by the rotation driving part1150, the control part may control the second conveyor belt1142and the third conveyor belt1143such that the second conveyor belt1142and the third conveyor belt1143move in opposite directions.

When the mattress10placed on the second frame1112is rotated by the rotation driving part1150, there is a risk that the mattress10is not smoothly rotated due to a frictional force between the mattress10and the conveyor belt1140.

In order to prevent such a phenomenon, the control part may control the second conveyor belt1142and the third conveyor belt1143such that the second conveyor belt1142and the third conveyor belt1143move in opposite directions.

Specifically, referring toFIG.10, when the mattress10is rotated by the rotation driving part1150, the upper portion (a portion coming in contact with the rotation driving part1150) of the mattress10is rotated leftward with respect toFIG.10, and a lower portion (a portion opposite to the portion coming in contact with the rotation driving part1150) of the mattress10is rotated rightward with respect toFIG.10.

Accordingly, the control part may control such that the second conveyor belt1142moves leftward with respect toFIG.10and the third conveyor belt1143moves rightward with respect toFIG.10. The mattress10may be easily rotated by the above-described operation of the control part and the rotation driving part1150.

Here, the other side of the frame1110may be divided by the third shaft1133so that an area of the third frame1113is larger than an area of the second frame1112.

As described above, the third shaft1133may horizontally divide the other side of the frame1110unequally, and when the other side of the frame1110is divided through the third shaft1133, the area of the third frame1113may be larger than the area of the second frame1112.

Since the rotation driving part1150is provided on the side surface of the second frame1112and rotates, a rotation radius of the mattress10in the portion of the third frame1113is larger than the rotation radius of the mattress10in the portion of the second frame1112.

That is, when the mattress10is rotated by the rotation driving part1150, the mattress10in the portion of the third frame1113should be rotated with a larger radius. Accordingly, the mattress10may be easily rotated when the lower portion (a portion opposite to the portion coming in contact with the rotation driving part1150) of the mattress10placed on the third frame1113receives a greater force.

To this end, the area of the third frame1113may be larger than the area of the second frame1112, and as the area of the third frame1113is increased, a greater force may be provided to the lower portion of the mattress10.

In addition, in order to rotate the mattress10in the target direction, the control part may control the second conveyor belt1142and the third conveyor belt1143such that the second conveyor belt1142and the third conveyor belt1143move at the same speed.

Since there is a risk that the mattress10is rotated in a direction different from the target direction when the second conveyor belt1142and the third conveyor belt1143do not move at the same speed, the control part may control the second conveyor belt1142and the third conveyor belt1143such that the second conveyor belt1142and the third conveyor belt1143move at the same speed.

However, the present disclosure is not limited thereto, and the control part may control the second conveyor belt1142and the third conveyor belt1143to move at different speeds depending on the size of the mattress10or the direction in which the mattress10rotates.

Referring toFIG.11, the mattress edge sewing apparatus having a rotation driving part according to an embodiment of the present disclosure may further include a turnover part1170formed in a bar shape. The turnover part1170may be installed on the second shaft1132, and has one side coupled to the second shaft1132, and thus the other side of the turnover part1170may rotate toward the upper portion of the frame1110around the coupled one side.

The turnover part1170may be used to turn the mattress10over. The turnover part1170may be raised while rotating in an upward direction in which an upper surface of the frame1110faces. One side of the turnover part1170may be coupled to the second shaft1132, and may be coupled to the second shaft1132at a position close to the first shaft1131.

When the mattress10is placed on the first frame1111and the fourth frame1114, the turnover part1170turns the mattress10over while rotating around one side thereof coupled to the second shaft1132. The overturned mattress10is moved to the second frame1112and the third frame1113.

The mattress edge sewing apparatus having a rotation driving part according to an embodiment of the present disclosure may operate as follows.

The mattress10is formed in a rectangular shape and has a predetermined thickness, and each of four edges of the mattress10should be sewn at the upper and lower surfaces of the mattress10.

The mattress10is first placed on the first frame1111and the fourth frame1114and passes through the processing part1120, thereby sewing one edge of the The mattress10that has passed through the processing part1120is moved to the second frame1112and the third frame1113, and the mattress10moved to the second frame1112and the third frame1113may be rotated by the rotation driving part1150and the driving part1160.

In this case, the control part controls such that the second conveyor belt1142provided in the second frame1112and the third conveyor belt1143provided in the third frame1113move in opposite directions so that the mattress10rotates easily.

When the mattress10is rotated by the rotation driving part1150, the conveyor belt1140is operated to place the mattress10again on the first frame1111and the fourth frame1114. Thereafter, another edge of the mattress10is sewn. All of the four edges of the mattress10may be sewn while repeating the above-described process.

Since the mattress10has a certain thickness, both the upper and lower surfaces of the mattress10should be sewn in order to manufacture the mattress10. After all of the four edges of the upper surface of the mattress10are completely sewn, the mattress10may be turned over by the turnover part1170so that the four edges of the lower surface of the lower surface of the mattress10are sewn.

Specifically, when the mattress10is placed on the first frame1111and the fourth frame1114, the mattress10is turned over while the turnover part1170is rotated. The overturned mattress10is moved to the second frame1112and the third frame1113, and the mattress10moved to the second frame1112and the third frame1113is moved again to the first frame1111and the fourth frame1114by the operation of the conveyor belt1140.

When the upper and lower surfaces of the mattress10are turned over by the turnover part1170, and then, the mattress10is placed on the first frame1111and the fourth frame1114and the above-described process is repeated, the four edges of the lower surface of the mattress10may be sewn.

The mattress edge sewing apparatus having a rotation driving part according to an embodiment of the present disclosure has the following effects.

In the mattress edge sewing apparatus having a rotation driving part according to an embodiment of the present disclosure, four edges of the mattress10can be processed while easily rotating the mattress10by pushing and rotating the mattress10through the rotation driving part1150while adjusting the directions of the conveyor belts1140provided in the frames1110.

The mattress10according to an embodiment of the present disclosure is formed in a rectangular shape and has a predetermined thickness, and each of the four edges of the mattress10should be sewn at the upper and lower surfaces of the mattress10.

In the mattress edge sewing apparatus having a rotation driving part according to an embodiment of the present disclosure, four edges of the upper surface of the mattress10can be processed while rotating the mattress10through the operation of the rotation driving part1150and the conveyor belt1140. Thereafter, four edges of the lower surface of the mattress10can be processed as the mattress10is turned over by the turnover part1170.

Hereinafter, a sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

The present disclosure relates to a sewing apparatus having a sheet support using a rotating ball, and relates to a sewing apparatus having a sheet support using a rotating ball, capable of processing an edge of a sheet by easily rotating the sheet by providing a rotating ball in a frame of a processing device configured to process an edge of a sheet.

A sheet processed by the sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure may be a sheet placed on the mattress, but the present disclosure is not limited thereto, and the sheet may be a mattress.

In addition, a processing operation performed in the sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure may be a sewing operation through a sewing apparatus such as a sewing machine, but is not limited thereto, and may include various operations as long as they are operations that process an edge of a sheet or a mattress.

Referring toFIG.12, the sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure includes a frame2110, a processing part2120, and a rotating ball2130.

The frame2110is a work bench on which a mattress10is placed, and may be formed of a frame in which a plate is installed in an upper portion thereof so that an edge of the mattress10may be processed thereon. The frame2110may be formed in various shapes as long as the mattress10is placed and processed thereon.

The processing part2120may be disposed on one side of the frame2110, and may process an edge of the mattress10. The processing part2120is a device capable of sewing an edge of the mattress10, and may be a device such as a sewing machine.

However, the processing part2120is not limited to the sewing machine, and may include various devices as long as they are devices capable of processing an edge of the mattress10. For example, the processing part2120may be a device configured to seal and sew an edge of the mattress10.

An edge of the mattress10may be processed while passing through the processing part2120. The mattress10is formed in a rectangular shape, and after one edge of the mattress10passes through the processing part2120, the mattress10is rotated so that another edge of the mattress10is processed.

A configuration capable of rotating a sheet is not provided in a conventional sheet processing device. Since a sheet has a large volume and a significant weight, through the conventional sheet processing device, it is difficult to process the sheet while rotating the sheet.

In order to solve the above problem, the sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure may use the rotating balls2130.

The rotating ball2130is provided in the frame2110, and an insertion groove2111for inserting the rotating ball2130therein is formed in the frame2110. The rotating ball2130is inserted into the insertion groove2111, and is rotatable as a portion thereof protrudes from an upper portion of the frame2110.

A plurality of rotating balls2130may be provided in the frame2110, and the plurality of rotating balls2130may be formed to be spaced apart from each other. Referring toFIGS.12and13, the mattress10is brought into contact with the rotating balls2130while being placed on the frame2110, and as the rotating balls2130are rotatable, the mattress10placed on the frame2110may be easily rotated.

In general, the mattress10is difficult to rotate due to a frictional force generated between the mattress10and the frame2110. However, when the rotatable rotating ball2130is used, the frictional force generated between the mattress10and the frame2110may be reduced, and as the rotating ball2130rotates, the mattress10may be easily rotated.

Referring toFIG.14, the rotating ball2130may be formed in a spherical shape. The insertion groove2111may be formed in a spherical shape, and may be formed in a spherical shape whose upper portion is partially cut away.

An upper end of the rotating ball2130may be in contact with the mattress10when a portion of the rotating ball2130protrudes from the frame2110, and as the insertion groove2111is formed in a spherical shape whose upper portion is cut away, an upper portion of the rotating ball2130formed in a spherical shape may protrude from the frame2110.

The rotating ball2130is rotatable by 360° while being inserted into the insertion groove2111, and the mattress10may be rotated or moved in various directions through the rotating ball2130rotatable by 360°.

According to an embodiment of the present disclosure, the rotating ball2130is formed in a spherical shape, and the insertion groove2111may be formed in a spherical shape whose upper portion is partially cut out, but the present disclosure is not limited thereto. As long as the rotating ball2130can be rotated while partially protruding above the frame2110, each of the rotating ball2130and the insertion groove2111may be formed in various shapes.

Referring toFIG.15A, a roller2131in contact with the rotating ball2130may be provided on an inner circumferential surface of the insertion groove2111. The roller2131may be used to reduce the frictional force between the rotating ball2130and the insertion groove2111, and may be provided between the rotating ball2130and the insertion groove2111.

When the mattress10comes into contact with the rotating ball2130, the rotating ball2130is pressed by the weight of the mattress10, and thus, the rotating ball2130may be brought into contact with the inner circumferential surface of the insertion groove2111.

When the rotating ball2130is brought into contact with the inner circumferential surface of the insertion groove2111, the rotation of the rotating ball2130may be restricted by the frictional force generated between the rotating ball2130and the inner circumferential surface of the insertion groove2111.

The roller2131is provided to prevent such a phenomenon, and may reduce the frictional force generated between the rotating ball2130and the inner circumferential surface of the insertion groove2111by having the roller2131rotatable around one axis between the rotating ball2130and the inner circumferential surface of the insertion groove2111.

Referring toFIG.15B, a spring2132may also be provided between the insertion groove2111and the rotating ball2130. The spring2132may push the rotating ball2130to the outside when the rotating ball2130is pressed by the mattress10.

As described above, the rotation of the rotating ball2130may be restricted by the frictional force generated between the rotating ball2130and the inner circumferential surface of the insertion groove2111. However, when the spring2132is provided between the rotating ball2130and the inner circumferential surface of the insertion groove2111, a contact area between the rotating ball2130and the insertion groove2111may be reduced by an elastic restoring force of the spring2132.

Specifically, as the spring2132pushes up the rotating ball2130in an outward direction (an upward protruding direction of the frame2110), the contact area between the rotating ball2130and the insertion groove2111may be reduced, and accordingly, the frictional force generated between the rotating ball2130and the inner circumferential surface of the insertion groove2111may be reduced.

Referring toFIG.13, the plurality of rotating balls2130provided in the frame2110may be spaced apart from each other at an interval of 30 cm to 40 cm. When the interval of the plurality of rotating balls2130is too large (greater than 40 cm), the contact area between the mattress10and the frame2110may be increased due to the weight of the mattress10.

When the contact area between the mattress10and the frame2110is increased, the frictional force between the mattress10and the frame2110may increase, and thus the mattress10may be difficult to rotate. Thus, the interval between the plurality of rotating balls2130provided in the frame2110may be less than 40 cm.

On the contrary, when the interval between the plurality of rotating balls2130is too small (less than 30 cm), an excessive number of the rotating balls2130are formed in the frame2110, and thus, it is difficult to adjust a rotation direction of the mattress10. Thus, the interval between the plurality of rotating balls2130provided in the frame2110may be greater than 30 cm.

Referring toFIGS.16A and16B, the rotating ball2130may be installed to be raisable and lowerable inside the insertion groove2111. When the edge of the mattress10is being processed by operating the processing part2120, it is preferable that the rotating ball2130is not in contact with the mattress10.

When the rotating ball2130is in contact with the mattress10when the edge of the mattress10is being processed through the processing part2120, the operation of the processing part2120may be affected by the rotation of the rotating ball2130.

Thus, when the edge of the mattress10is being processed through the processing part2120, it is preferable that the rotating ball2130is not in contact with the mattress10. To this end, the rotating ball2130may be installed to be raisable and lowerable inside the insertion groove2111.

Specifically, the rotating ball2130may be installed such that a portion of the rotating ball2130does not protrude above the frame2110when the rotating ball2130is lowered, and protrudes above the frame2110when the rotating ball2130is raised.

A moving part2112may be provided between the rotating ball2130and the inner circumferential surface of the insertion groove2111in order to raise or lower the rotating ball2130. The moving part2112may move up or down the rotating ball2130while being in contact with one side of the rotating ball2130, and may slidably move toward inside the insertion groove2111.

The sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure may further include a switch2140capable of controlling the operation of the moving part2112. The switch2140is a device capable of slidably moving the moving part2112, and the raising or lowering of the rotating ball2130may be controlled through the switch2140.

A user may raise the rotating ball2130through the switch2140only when the mattress10is rotated, and may lower the rotating ball2130through the switch2140when the edge of the mattress10is processed through the processing part2120.

Referring toFIG.17, the sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure may operate the moving part2112through the switch2140, and may also operate the moving part2112through a control part2150and a sensor part2160.

The control part2150may control the operation of the moving part2112, and may raise the rotating ball2130by operating the moving part2112when the mattress10is rotated as the operation of the processing part2120is stopped.

When an edge of the mattress10is being processed by operating the processing part2120, the rotating ball2130may be lowered. When the rotating ball2130is raised when the edge of the mattress10is being processed through the processing part2120, the operation of the processing part2120may be affected by the rotation of the rotating ball2130.

Accordingly, the control part2150may control the moving part2112such that the rotating ball2130is lowered when the processing part2120is operated, and control the moving part2112such that the rotating ball2130is raised only when the processing part2120is not operated.

The control part2150may detect whether the mattress10is placed on the upper portion of the frame2110using the sensor part2160, and may detect whether the mattress10is rotated using the sensor part2160.

Referring toFIG.18, the sensor part2160may be provided on the upper portion of the frame2110, and whether the mattress10is placed or not and rotated or not may be detected by the sensor part2160. Various sensors may be used for the sensor part2160as long as they can detect whether the mattress10is placed or not and rotated or not.

The control part2150may detect whether the mattress10is rotated using the sensor part2160, and may also automatically raise the rotating ball2130only when the mattress10is rotated as the operation of the processing part2120is stopped.

Here, the control part2150is connected to the processing part2120, and the control part2150may recognize whether the processing part2120operates. In addition, the control part2150may be disposed at various points as long as the operation of the moving part2112can be controlled while receiving signals of the sensor part2160.

In the sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure, an alignment bar2170protruding above the frame2110and being in contact with one side of the mattress10may be provided in the frame2110.

Referring toFIG.19, the alignment bar2170is disposed on a line extending from the processing part2120, protrudes above the frame2110, and is capable of supporting the mattress10while being in contact with one side of the mattress10.

The alignment bar2170may align one side of the mattress10so that the mattress10may pass in a straight line without shaking when passing through the processing part2120, and due to the alignment bar2170, a target edge point of the mattress10may pass through the processing part2120without shaking.

The alignment bar2170is described as being disposed on the line extending from the processing part2120, but is not limited thereto, and may be disposed at various points as long as it can align the mattress10while being in contact with one side of the mattress10.

The alignment bar2170may also be installed to be raisable and lowerable in the frame2110. As described above, the mattress10should rotate after one side edge thereof is processed.

However, when the alignment bar2170protrudes above the frame2110, the rotation of the sheet may be hindered by the alignment bar2170. Thus, when the mattress10rotates, it is preferable that the alignment bar2170does not protrude above the frame2110.

To this end, referring toFIGS.20A and20B, the alignment bar2170is raisable or lowerable in an inner direction of the frame2110, so that the alignment bar2170protrudes above the frame2110or does not protrude above the frame2110.

Here, the operation of the alignment bar2170may be controlled through the control part2150. The control part2150controls the alignment bar2170to be lowered in the inner direction of the frame2110when the rotating ball2130is raised by the moving part2112.

Since the phrase “the rotating ball2130is raised” indicates that the mattress10rotates, when the rotating ball2130is raised, the control part2150controls the alignment bar2170to be lowered in the inner direction of the frame2110.

Thereafter, when the rotating ball2130is lowered, the control part2150may align the mattress10while raising the alignment bar2170so as to protrude above the frame2110.

The sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure has the following effects.

In the sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure, the rotating ball2130is provided in the frame2110of the processing device configured to process an edge of the mattress10, so that the edge of the mattress10can be processed while easily rotating and moving the mattress10.

In particular, in the sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure, the raising or lowering of the rotating ball2130is controlled through the control part2150, so that the rotating ball2130can be controlled to be raised only when the mattress10is rotated.

In addition, in the sewing apparatus having a sheet support using a rotating ball according to an embodiment of the present disclosure, an edge point of the mattress10to be processed can accurately pass through the processing part2120by the alignment bar2170, and the alignment bar2170is controlled through the control part2150, so that the mattress10can rotate without being hindered by the alignment bar2170during rotation.

Hereinafter, a sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

The present disclosure relates to a sewing apparatus having a sheet support using an air compressor, and relates to a sewing apparatus having a sheet support using an air compressor, capable of processing an edge of a sheet by easily rotating the sheet by providing an air compressor in a frame of a processing device configured to process an edge of a sheet.

A sheet processed by the sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure may be a sheet placed on the mattress, but the present disclosure is not limited thereto, and the sheet may be a mattress.

In addition, a processing operation performed in the sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure may be a sewing operation through a sewing apparatus such as a sewing machine, but is not limited thereto, and may include various operations as long as they are operations that process an edge of a sheet or a mattress.

Referring toFIG.21, the sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure includes a frame3110, a processing part3120, and an air compressor3130.

The frame3110is a work bench on which a mattress10is placed, and may be formed of a frame in which a plate is installed in an upper portion thereof so that an edge of the mattress10may be processed thereon. The frame3110may be formed in various shapes as long as the mattress10is placed and processed thereon.

The processing part3120may be disposed on one side of the frame3110, and may process an edge of the mattress10. The processing part3120is a device capable of sewing an edge of the mattress10, and may be a device such as a sewing machine.

However, the processing part3120is not limited to the sewing machine, and may include various devices as long as they are devices capable of processing an edge of the mattress10. For example, the processing part3120may be a device configured to seal and sew an edge of the mattress10.

An edge of the mattress10may be processed while passing through the processing part3120. The mattress10is formed in a rectangular shape, and after one edge of the mattress10passes through the processing part3120, the mattress10is rotated so that another edge of the mattress10is processed.

A configuration capable of rotating a sheet is not provided in a conventional sheet processing device. Since the sheet has a large volume and a significant weight, through the conventional sheet processing apparatus, it is difficult to process the sheet while rotating the sheet.

In order to solve the above problem, the sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure may use the air compressor3130.

The air compressor3130is provided below the frame3110and is capable of spraying air into the frame3110. The air compressor3130may include various devices as long as they are devices capable of spraying air into the frame3110,

Referring toFIG.22, the frame3110may include a plurality of air spraying holes3111through which air sprayed from the air compressor3130may be discharged to the outside. The plurality of air spraying holes3111are provided to be spaced apart from each other, and air is sprayed from each of the plurality of air spraying holes3111.

The mattress10may be placed on an upper portion of the air spraying hole3111, and may receive pressure of the air sprayed from the air spraying hole3111. The mattress10may be raised upwards by the pressure of the air sprayed from the air spraying hole3111.

The mattress10is difficult to rotate due to a frictional force generated between the mattress10and the frame3110. However, when the mattress10is raised by the air sprayed from the air compressor3130, the frictional force generated between the mattress10and the frame3110is reduced, so that the mattress10may be easily rotated.

Here, the mattress10is slightly raised by the air sprayed from the air compressor3130, and the mattress10may be raised only to the extent that the mattress10and the frame3110are not in contact with each other.

Referring toFIG.22, the plurality of air spraying holes3111provided in the frame3110may be spaced apart from each other at an interval of 40 cm to 50 cm. When the interval of the plurality of air spraying holes3111is to large (greater than 50 cm), sufficient force may not be supplied to the mattress10.

In addition, when the interval between the plurality of air spraying holes3111is too large (greater than 50 cm), a separation distance between points at which the mattress10receives force by air pressure increases, and thus the balance of the mattress10may be destroyed. Accordingly, the separation distance between the air spraying holes3111may less than 50 cm.

On the contrary, when the interval between the plurality of air spraying holes3111is too small (less than 40 cm), excessive force may be applied to the mattress10. When the mattress10is raised only to the extent that the frictional force is not generated between the mattress10and the frame3110, the mattress10is easily rotated.

Accordingly, it is not necessary to apply excessive force to the mattress10, and air may be sprayed so that the mattress10is raised only to the extent that the frictional force is not generated between the mattress10and the frame3110. Thus, the interval between the plurality of air spraying holes3111may be greater than 40 cm.

The sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure may further include a switch3140capable of controlling the operation of the air compressor3130. The switch3140is a device capable of turning the air compressor3130on/off, and the user may operate the air compressor3130only when the mattress10is rotated.

Referring toFIGS.23and24, the sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure may further include a control part3150configured to control air spraying from the air compressor3130, and a sensor part3160capable of detecting whether the mattress10is placed on the frame3110.

Referring toFIG.23, the sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure may be operated through the switch3140, and may also be operated through the control part3150and the sensor part3160.

The control part3150may control the air spraying from the air compressor3130, and the control part3150may control the air compressor3130to spray air into the frame3110when the operation of the processing part3120is stopped and the mattress10is rotated.

When an edge of the mattress10is processed by operating the processing part3120, the operation of the air compressor3130may be stopped. When air is sprayed from the air compressor3130when the edge of the mattress10is processed through the processing part3120, this may affect the operation of the processing part3120.

Accordingly, the control part3150may control the air compressor3130so that air is not sprayed from the air compressor3130when the processing part3120is operated, and air is sprayed from the air compressor3130only when the processing part3120is not operated.

The control part3150may detect that the mattress10is placed on the upper portion of the frame3110using the sensor part3160. Various sensors may be used for the sensor part3160as long as they can detect whether the mattress10is placed on the frame3110.

The control part3150may control air to be sprayed from the air compressor3130only when the sensor part3160detects that the mattress10is placed on the frame3110.

The sensor part3160may also detect whether the mattress10rotates. Referring toFIG.24, the sensor part3160may be provided on the upper portion of the frame3110, and whether the mattress10is rotated or not may be detected by the sensor part3160. Various sensors may be used for the sensor part3160as long as they can detect whether the mattress10is rotated or not.

The control part3150may detect whether the mattress10is rotated using the sensor part3160, and may also control the air compressor3130to automatically spray air when the mattress10is rotated as the operation of the processing part3120is stopped.

Here, the control part3150is connected to the processing part3120, and the control part3150may recognize whether the processing part3120operates. In addition, the control part3150may be disposed at various points as long as the operation of the air compressor3130can be controlled while receiving signals of the sensor part3160.

The control part3150may also control the air compressor3130such that the pressure of the air sprayed from each of the plurality of air spraying holes3111is different from each other. As described above, the plurality of air spraying holes3111are provided in the frame3110, and since the pressure of the air sprayed from each of the plurality of air spraying holes3111is different from each other, the mattress10may be easily rotated.

According to an embodiment, the control part3150controls such that the pressure of the air sprayed from the air spraying hole disposed in a center portion of the mattress10is formed to be greater than the pressure of the air sprayed from the air spraying hole disposed in a periphery of the mattress10.

When the pressure of the air sprayed from the air spraying hole disposed in the center portion of the mattress10is formed to be great, a large force may be applied to a center of the mattress10to form a central axis around which the mattress10rotates. Accordingly, the mattress10may be easily rotated.

The control part3150may detect the center portion of the mattress10using the sensor part3160. The sensor part3160may detect a shape of the mattress10, and as the sensor part3160detects the shape of the mattress10, the control part3150may recognize a center point of the mattress10.

Here, the center portion of the mattress10may be an inside of a circle having a diameter of 50 cm to 200 cm with respect to the center point of the mattress10, and the periphery of the mattress10may be a portion other than the center portion of the mattress10.

The control part3150may also control the air compressor3130such that air is sprayed only from some of the plurality of air spraying holes3111. The control part3150may control such that air is sprayed only from some of the plurality of air spraying holes3111according to a direction in which the mattress10rotates, and thus, the mattress10may be easily rotated.

In the sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure, an alignment bar3170protruding above the frame3110and being in contact with one side of the mattress10may be provided in the frame3110.

Referring toFIG.25, the alignment bar3170is disposed on a line extending from the processing part3120, protrudes above the frame3110, and is capable of supporting the mattress10while being in contact with one side of the mattress10. The alignment bar3170may align one side of the mattress10so that the mattress10may pass in a straight line without shaking when passing through the processing part3120, and due to the alignment bar3170, a target edge point of the mattress10may pass through the processing part3120without shaking.

The alignment bar3170is described as being disposed on the line extending from the processing part3120, but is not limited thereto, and may be disposed at various points as long as it can align the mattress10while being in contact with one side of the mattress10.

The alignment bar3170may be installed to be raisable and lowerable in the frame3110. As described above, the mattress10should rotate after one side edge thereof is processed.

However, when the alignment bar3170protrudes above the frame3110, the rotation of the sheet may be hindered by the alignment bar3170. Thus, when the mattress10rotates, it is preferable that the alignment bar3170does not protrude above the frame3110.

To this end, referring toFIGS.26A and26B, the alignment bar3170is raisable or lowerable in an inner direction of the frame3110, so that the alignment bar3170protrudes above the frame3110or does not protrude above the frame3110.

Here, the operation of the alignment bar3170may be controlled through the control part3150. When air is sprayed into the frame3110from the air compressor3130, the control part3150controls the alignment bar3170to be lowered in the inner direction of the frame3110.

Since the phrase “air is sprayed from the air compressor3130” indicates that the mattress10rotates, when air is sprayed into the frame3110from the air compressor3130, the control part3150control the alignment bar3170to be lowered in the inner direction of the frame3110.

Thereafter, when air is not sprayed from the air compressor3130, the control part3150controls the alignment bar3170to be raised so that the alignment bar3170protrudes above the frame3110, thereby aligning the mattress10.

The sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure has the following effects.

The sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure includes the air compressor3130configured to spray air into the frame3110of the processing device that processes an edge of the mattress10, so that the edge of the mattress10can be processed while easily rotating and moving the mattress10.

In particular, in the sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure, the air compressor3130can be controlled by the control part3150, and an spraying pressure or spraying point of each of the plurality of air spraying holes3111can be controlled, so that the mattress10can easily be rotated.

In addition, in the sewing apparatus having a sheet support using an air compressor according to an embodiment of the present disclosure, an edge point of the mattress10to be processed may accurately pass through the processing part3120by the alignment bar3170, and the alignment bar3170is controlled through the control part3150, so that the mattress10can rotate without being hindered by the alignment bar3170during rotation.
