Description

The present invention relates to a packed rug, a rug packing device and a packing method.

In recent years, the cost of transporting mattresses and the like has soared, and in particular, for mattresses and the like larger than a predetermined size, the transportation itself may be refused.
Therefore, conventionally, a compression packaging method for a mattress in which the mattress is compressed to degas the air contained therein and the surrounding area is sealed with an airtight bag, and a compression mattress are known (Patent Document 1). reference).

In the compression packaging method of Patent Document 1, after the mattress is placed in the airtight bag, the bag is urged in a direction close to each other from the closed portion side to the open portion side of the bag. The process of compressing the mattress together, the process of holding the inside of the bag in a sealed state by sandwiching the vicinity of the opening of the bag with rollers after the inner mattress has passed through the roller, and the process of sealing the vicinity of the opening of the bag during this period. It has a process to do.
Further, in the compression mattress of Patent Document 1, the mattress placed in an airtight bag is compressed together with the bag by a roller, and the opening of the bag is sealed in that state.

Japanese Unexamined Patent Publication No. 2004-010119

However, in the compression packaging method and compression mattress of the mattress described in Patent Document 1, since the inside of the bag is kept in a sealed state, even if the mattress is taken out from the sealed bag and used, the compressed mattress is before compression. There is a risk that the original performance of the mattress cannot be exhibited without returning to the state of.
Further, the device that performs the compression packaging method of Patent Document 1 also needs a function of keeping the inside of the bag in a sealed state and sealing the vicinity of the opening of the bag, so that there is a problem that the device becomes complicated and large. is there.

In view of these points, the present invention covers the roll peripheral surface of the rug wound in a roll shape with a packing sheet, but by exposing the roll end face of the rug without covering it with the packing sheet, the rug can be "transported, etc." It is an object of the present invention to provide a packed rug, a rug packing device and a packing method capable of achieving both "compactification" and "improvement of the return force to the state before packing" and "miniaturization of the packing device".

The rug 1 according to the present invention is a packed rug, the rug is rolled in a roll shape, the roll peripheral surface 1a of the rug is covered with a packing sheet 2, and the roll end surface 1b of the rug is the said. The first feature is that the packing sheet 2 is not covered and is exposed.

The second feature of the rug 1 according to the present invention is that, in addition to the above first feature, a gap 3 is provided in the roll center portion 1c of the rug.

The third feature of the rug 1 according to the present invention is that, in addition to the above-mentioned first or second feature, the rug is wound in a roll shape in a predetermined folded state.

Due to these features, by covering the roll peripheral surface 1a of the roll-shaped rug 1 with the packing sheet 2, the size of the rug 1 becomes smaller, it becomes easier to carry and store it, and the cost of carrying it also decreases. it can.
At the same time, by exposing the roll end surface 1b of the rug 1 without covering it with the packing sheet 2, unlike Patent Document 1, it is not necessary to keep the inside of the bag in a sealed state, and the rug 1 is unpacked. When used, the rug 1 is not excessively compressed by the amount that the roll end face 1b is exposed, so that the rug 1 can easily return to the state before packing (so to speak, the force to return to the state before packing is improved. ), It becomes easier to demonstrate the original performance of the rug 1.
Therefore, it is possible to achieve both "compactness during transportation" and "improvement of the return force to the state before packing" of the rug 1.
This also leads to the miniaturization of the packing device 20 of the rug 1 described later.

Further, by providing the gap 3 in the roll center 1c of the rug 1, the rug 1 swells in the roll center 1c direction after packing by the amount of the gap 3 while maintaining the compactness of the packed rug 1. Since it is possible to (return) and the return force to the pre-packing state is further improved, it is possible to further achieve both "compactness during transportation" and "improvement of the return force to the pre-packing state".

Further, by winding the rug 1 in a roll shape in a state of being folded and folded in a predetermined manner, the size of the rug 1 can be reduced before the rug 1 is wound in a roll shape, and further "compactification during transportation" can be realized.

The packing device 20 for the rug 1 according to the present invention is a packing device for packing the rug 1, and the roll winding portion 21 for winding the rug 1 in a roll shape and the roll peripheral surface 1a of the rug 1 are packed with a packing sheet 2. The first feature is that it has a sheet peripheral covering portion 22 that covers and exposes the roll end surface 1b of the rug 1 without being covered by the packing sheet 2.

Due to this feature, the roll winding portion 21 that winds the rug 1 in a roll shape and the roll peripheral surface 1a of the rug 1 are covered with the packing sheet 2 and the roll end surface 1b of the rug 1 is not covered by the packing sheet 2 and is exposed. By having 22, the size of the packing device 20 can be reduced by the amount that the function of keeping the inside of the bag in a sealed state or sealing the vicinity of the opening of the bag is not required, unlike Patent Document 1 (“Packing”. Equipment miniaturization ").
At the same time, as described above, the rug 1 packed by the packing device 20 can achieve both "compactness during transportation" and "improvement of the return force to the state before packing".

The packing method of the rug 1 according to the present invention is a packing method for packing the rug 1, wherein the roll winding step K1 for winding the rug 1 in a roll shape and the roll peripheral surface 1a of the rug 1 are covered with the packing sheet 2. The first feature is to have a sheet covering step K2 that exposes the roll end surface 1b of the rug 1 without being covered by the packing sheet 2.

The same applies to this feature, and the roll winding step K1 in which the rug 1 is wound in a roll shape and the sheet circumference in which the roll peripheral surface 1a of the rug 1 is covered with the packing sheet 2 and the roll end surface 1b of the rug 1 is not covered by the packing sheet 2 and exposed. By having the covering step K2, unlike Patent Document 1, "miniaturization of the packing device" can be realized, and as described above, the rug 1 packed by this packing method is "compacted during transportation, etc." "And" improvement of the return force to the state before packing "can be achieved at the same time.

According to the packed rug, the rug packing device, and the packing method according to the present invention, the roll peripheral surface of the rolled rug is covered with a packing sheet, but the roll end face of the rug is not covered with the packing sheet and is exposed. As a result, it is possible to achieve both "compactness during transportation" and "improvement of the return force to the state before packing" and "miniaturization of the packing device".

For example, the gap 3 is a roll center axis (in the case of a substantially cylindrical cylinder, its rotation axis) in the roll-shaped rug 1. It may be provided so as to penetrate from one roll end face 1b to the other roll end face 1b substantially along the axis corresponding to), and the gap 3 is substantially along the roll center axis, but the roll center axis. Even if a gap 3 is provided only in the middle portion in the direction, or a gap 3 is provided only near one roll end face 1b and / or the other roll end face 1b (that is, from one roll end face 1b to the other roll). It does not matter if the gap 3 does not penetrate up to the end face 1b).

The size of the gap 3 is also not particularly limited, but when the gap 3 is provided substantially along the roll central axis, its diameter (when the opening shape of the gap 3 is substantially circular) is, for example, 0.1 cm. It may be 10.0 cm or more, preferably 0.2 cm or more and 8.0 cm or less, and more preferably 0.5 cm or more and 5.0 cm or less.
When the gap 3 is provided substantially along the central axis of the roll, the length thereof is also not particularly limited, and is, for example, substantially the same length as the width of the rug 1 wound in a roll shape and / or folded in a predetermined manner ( If it is substantially columnar, it may have a length corresponding to its height), and may be shorter than the width of the rug 1 that is rolled and / or folded in a predetermined manner (for example,). Even if the length is approximately 1/2, 1/3, 1/4, 2/3, 3/4, etc., which is approximately the same as the width of the rug 1 that is rolled and / or folded in a predetermined manner. I do not care.

The size (diameter, etc.) of the provided gap 3 may apparently gradually decrease after packing the rug 1, and this means that the rug 1 rolls after packing by the amount of the gap 3 provided. It will swell (return) in the direction of the central portion 1c.
Further, even when the gap 3 is apparently very small, for example, a human finger (index finger or the like), a rod (cylinder) having a diameter of 1 cm, or the like is wound in a roll shape in the roll center 1c of the rug 1. If it can be inserted substantially along the roll central axis, it can be said that the gap 3 is provided only by apparently reducing the gap 3.

<Packing device 20 for rug 1>
As shown in FIGS. 1 to 4 and 9 to 22, the packing device 20 for the rug 1 described above has a roll winding portion 21 and a sheet surrounding portion 22 described later.
The packing device 20 has a transport portion 23, a compression transport portion 24, a sandwiching portion 25, and an extrusion portion 26, and also has a folding portion (not shown) and a covering portion (not shown). You may be.

Further, the packing device 20 is a control unit (shown) that operates the support member 27 and the moving wheel 28 that support the roll winding portion 21 and the seat surrounding portion 22 and the like, the roll winding portion 21 and the seat surrounding portion 22 and the like. It may also have a power source (power source, etc., not shown) for operating the roll winding portion 21, the seat surrounding portion 22, and the like.
The size of the packing device 20 is not particularly limited as long as the above-mentioned rug 1 can be packed, but it can be said that at least the width of each part thereof is equal to or larger than the width of the predetermined folded rug 1.

<Roll winding part 21>
As shown in FIGS. 1 to 4 and 9 to 22, the roll winding portion 21 is a portion for winding the above-mentioned rug 1 in a roll shape.
The roll winding portion 21 may have any configuration as long as the rug 1 is wound in a roll shape. For example, the roll winding portion 21 has a winding core member 21a around which the rug 1 is wound and the winding core member. It may have a power member 21b for rotating the 21a and a transmission switching member (clutch member) 21c for switching the transmission method (transmission method) of the rotational force from the power member 21b to the winding core member 21a.

<Core member (lock member) 21a>
As shown in FIGS. 1 to 4 and 9 to 22, the winding core member 21a is an outer core material having a substantially tubular shape and a part of the peripheral surface opened in the axial direction (so-called a substantially C-shaped cross section). It has a 21a1 and an inner core material 21a2 which is substantially tubular and has a part of the peripheral surface opened in the axial direction (so-called a substantially C-shaped cross section) fitted inside the outer core material 21a1. There is.
The cross-sectional shapes of the outer core material 21a1 and the inner core material 21a2 are substantially similar, and the inner core material 21a2 can rotate around the axial centers of the core materials 21a1 and 21a2 inside the outer core material 21a1 (inner core). The relative position (relative angle) of the material 21a2 can be changed with respect to the outer core material 21a1).

In this way, by changing the relative angle of the inner core material 21a2 with respect to the outer core material 21a1 (for example, the inner core material 21a2 is rotated by approximately 60 to 90 ° with respect to the outer core material 21a1), as will be described later. Since one end 1d of the rug 1 inside the inner core member 21a2 is locked (held), it can be said that the winding core member 21a is a locking member (FIGS. 19 (a) and 19 (b)). 22 (a) and 22 (b)).
The openings of the outer core material 21a1 and the inner core material 21a2 may be any opening length or width as long as one end 1d of the rug is inside the inner core material 21a2, but in particular, the opening length. The length may be the same as that of the outer core material 21a1 and the inner core material 21a2.

The size of the winding core member 21a is also not particularly limited as long as the rug 1 is wound around, but for example, the length thereof may be longer than the width of the rug 1, and the thickness thereof may be, for example, 1.0 cm or more 8 It may be 0.0 cm or less, preferably 1.5 cm or more and 6.0 cm or less, and more preferably 2.0 cm or more and 5.0 cm or less.
Further, the thicknesses of the outer core material 21a1 and the inner core material 21a2 are not particularly limited as long as the inner core material 21a2 can rotate inside the outer core material 21a1, but the respective thicknesses are, for example, 0.5 mm. It may be 10.0 mm or more, preferably 1.0 mm or more and 8.0 mm or less, and more preferably 1.5 mm or more and 5.0 mm or less.

<Power member 21b>
As shown in FIGS. 10 and 13, the power member 21b has at least a power source 21b1 that generates a power (rotational force) for rotating the winding core member 21a described above.
In addition, the power member 21b may have a speed reducer 21b2 that reduces the power generated from the power source 21b1 described above at a predetermined rate.

The power source 21b1 may have any configuration as long as it can generate power (rotational force) for rotating the winding core member 21a. For example, in addition to a motor (electric motor) such as a servo motor or a stepping motor, gasoline, light oil, etc. It may be an engine (internal engine), a hydraulic motor, an air engine, a water turbine, a wind turbine, or the like.
Hereinafter, the power source 21b1 will be described as being mainly a servomotor.
When the power source 21b1 is a motor (electric motor), the electric power may be received from an outlet (commercial electric power), a storage battery, or the like.

The speed reducer 21b2 may have any configuration as long as the power generated from the above-mentioned power source 21b1 is reduced at a predetermined ratio. For example, a gear speed reducer using gears or a pulley is used. It may have a reduction ratio (number of teeth ratio or pulley ratio) of the pulley reducer or the like.
The reduction ratio of the speed reducer 21b2 is not particularly limited as long as the rug 1 winds around the winding core member 21a rotated by the power member 21b (provides the required torque and rotation speed), but is, for example, 1 or more and 50. Hereinafter, it may be preferably 1 or more and 20 or less, and more preferably 1 or more and 10 or less.

For example, when the reduction ratio is 10, "the output from the reduction gear 21b2 to the winding core member 21a when the input from the power source 21b1 to the reduction gear 21b2 (input gear in the reduction gear 21b2, etc.) rotates 10 times. (The output gear or the like in the speed reducer 21b2 or the winding core member 21a itself) makes one rotation. "
With such a power member 21b, the winding tension (winding tension or winding torque), speed (winding speed), and other winding core members 21a when the roll winding portion 21 winds the rug 1 in a roll shape from the first winding. It can be said that the rate of increase in the winding tension after one rotation of the wheel (that is, the winding tension is gradually increased and the winding (whether the winding is gradually tightened, etc.) can be adjusted).
In addition, when the packing sheet 2 is wound together with the rug 1 by the roll winding portion 21 (core member 21a), the length of the packing sheet 2 around the roll peripheral surface 1a of the rug 1 and the number of rotations of the packing sheet 2 It can be said that whether or not the winding is divided can be adjusted by the power member 21b.

<Transmission switching member (clutch member) 21c>
As shown in FIGS. 10, 11 and 13, the transmission switching member 21c may have any configuration as long as the method of transmitting the rotational force from the power member 21b to the winding core member 21a described above can be switched. , The coupler 21c'that transmits the rotational force generated from the power member 21b described above to the winding core member 21a (at least the inner core material 21a2) and the transmission of the rotational force from the coupler 21c' to the outer core material 21a1 are switched ( It may have a clutch 21c "that disengages and engages).

The coupler 21c'directs the rotational force output from the above-mentioned power member 21b (for example, the speed reducer 21b2) to the inner core member 21a2.
The coupler 21c'may have any configuration as long as the rotational force from the speed reducer 21b2 or the like is directly transmitted to the inner core material 21a2. For example, the coupler 21c'is substantially cylindrical and of the coupler 21c'. The tip side is directly connected to one end (base end) side of the inner core material 21a2 so as to be rotatable together with the coaxial center (more specifically, one end of the inner core material 21a2 (more specifically, in the hole on the tip side of the coupler 21c'). The base end) side may be fitted).

On the other hand, the base end side of the coupler 21c'is directly connected to the output shaft of the power member 21b (reducer 21b2) described above so as to be rotatable together with the coaxial center (more specifically, the base end of the coupler 21c'). The output shaft of the power member 21b (reducer 21b2) may be fitted in the hole on the side.
The coupler 21c'may be rotatably surrounded by an outer cylinder 21' that is a part of the exterior of the roll winding portion 21, and the outer cylinder 21'is also the roll winding portion 21'. It may be attached to the support plate 21 ”which is a part of the exterior of the above.
Further, the inner core material 21a2 is rotatably supported by the bearing (bearing) on the support plate 21 "and the bearing inside the substantially tubular meridian portion on the base end side of the outer core material 21a1. The outer core material 21a1 is attached to the side opposite to the outer cylinder material 21'in the support plate 21 "and is rotated by a bearing inside the tip of a substantially tubular member that surrounds most of the outer core material 21a1. It is supported freely.

The clutch 21c "may have any configuration as long as the transmission of the rotational force from the coupler 21c'to the outer core material 21a1 can be switched. For example, the clutch 21c" may be an electromagnetic clutch or a meshing clutch (cam clutch). ), A mechanical clutch, a liquid clutch, or the like may be used.
Hereinafter, the clutch 21c "will be described as being mainly an electromagnetic clutch 21c".

The electromagnetic clutch 21c "is a transmission of a rotational force from the coupler 21c'to the outer core material 21a1 by turning on / off the current (power supply) to the electromagnetic clutch 21c" (flowing or not flowing the current). It is a clutch that disengages and connects.
The electromagnetic clutch 21c "may have any configuration as long as the transmission of the rotational force from the coupler 21c'to the outer core material 21a1 can be switched. For example, the transmission of the rotational force when the power is off. It may be a non-excitation actuated type that connects the above, an excitation actuated type that connects the transmission of the rotational force when the power is on, a friction type, an meshing type, a void type, a spring type, or the like.

Hereinafter, the electromagnetic clutch 21c "will be described as being mainly a non-excitation actuated friction type.
The non-excitation actuated friction type electromagnetic clutch 21c ”has a coil 21c1 that generates a magnetic field when a current flows, a stator (holding material) 21c2 that holds the coil 21c1, and a coil 21c1 that is generated through the stator 21c2. An armature (armature) 21c3 that is attracted to the stator 21c2 side by the magnetic field of the above, a rotor 21c4 that is not connected to the armature 21c3 or the stator 21c2 and rotates together with the inner core material 21a2, and the rotor 21c4 and the stator. It may have a gap 21c5 that allows the armature 21c3 to move between the armature 21c2 and a torque spring (not shown) that presses the armature 21c3 and the rotor 21c4 against the base end side of the outer core material 21a1.

In the non-excitation actuated friction type electromagnetic clutch 21c ", the stator 21c2 is a support plate 21" which is a part of the exterior of the roll winding portion 21 (more specifically, the side opposite to the outer cylinder member 21'described above). Of course, unlike the inner core material 21a2 and the outer core material 21a1, it does not rotate.
On the other hand, the rotor 21c4 is formed in a flange shape in the middle of the base end of the inner core material 21a2, and naturally rotates together with the inner core material 21a2.

In the non-excitation actuated friction type electromagnetic clutch 21c ", the armature 21c3 has a substantially flat plate ring shape, and the gap 21c5 between the stator 21c2 and the rotor 21c4 allows the inner core material 21a2 to move in the axial direction. It fits.
When the power is off, the armature 21c3 is pressed against the rotor 21c4 by the torque spring, so that the rotor 21c4 is pressed against the base end side of the outer core material 21a1, and as a result, the coupler 21c is also pressed against the outer core material 21a1. The rotational force from'is transmitted (the transmission of the rotational force is connected), and the inner core material 21a2 and the outer core material 21a1 rotate together (the frictional force between the armature 21c3 and the rotor 21c4, and the rotor 21c4 and the outer core. The inner core material 21a2 and the outer core material 21a1 are rotated by the frictional force with the base end side of the material 21a1).
On the other hand, when the power is on, the armature 21c3 is attracted to the stator 21c2 side by the magnetic field generated by the coil 21c1 and is separated from the rotor 21c4. Therefore, the rotor 21c4 is pressed against the base end side of the outer core material 21a1. As a result, the rotational force from the coupler 21c'is not transmitted to the outer core material 21a1 (the transmission of the rotational force is cut off), and only the inner core material 21a2 is rotated (rotation from the coupler 21c'). The force is transmitted only to the inner core material 21a2).

In this way, the transmission switching member 21c having the electromagnetic clutch 21c "and the coupler 21c' cuts off or connects the transmission of the rotational force from the coupler 21c' to the outer core member 21a1 by turning the power on / off. Therefore, it can be said that the transmission switching member 21c is a clutch member.
When this power supply is ON (when the transmission of the rotational force from the coupler 21c'to the outer core member 21a1 is cut off), the rotational force from the power member 21b (reducer 21b2) and the coupler 21c' Therefore, the relative angle of the inner core material 21a2 with respect to the outer core material 21a1 can be changed (for example, the inner core material 21a2 is rotated by approximately 60 to 90 ° with respect to the outer core material 21a1).

The roll winding portion 21 having the winding core member 21a, the power member 21b, and the transmission switching member 21c described so far has the transmission switching member when one end 1d of the rug 1 enters the inside of the inner core member 21a2. By turning on the power to the 21c, the relative angle of the inner core material 21a2 with respect to the outer core material 21a1 is changed to lock one end 1d of the rug 1, and the locked state remains (inner core material). (While maintaining the relative angle between 21a2 and the outer core material 21a1), the power to the transmission switching member 21c is turned off, and the power member 21b rotates the inner core material 21a2 and the outer core material 21a1 together to rotate the winding core. The rug 1 is wound around the member 21a (outer core material 21a1) (the rug 1 is wound in a roll shape).
The roll winding portion 21 rolls the rug 1 so as to be close to or separated from the one end portion 1d when the one end portion 1d of the predetermined folded rug 1 is sandwiched between the sandwiching portions 25 described later. The entire portion 21 may be movable, and in particular, when the entire roll winding portion 21 is moved so as to be close to one end 1d of the rug 1, the one end 1d is the winding described above. It may be configured so as to be inside the core member 21a (inner core material 21a2).

<Sheet circumference 22>
As shown in FIGS. 1 to 4 and 9, the sheet peripheral covering portion 22 covers the roll peripheral surface 1a of the roll-shaped rug 1 with the packing sheet 2, and covers the roll end surface 1b of the rug 1 with the packing sheet. Depending on 2, it is a part that is exposed without being covered.
The sheet peripheral cover portion 22 may not cover all of the roll peripheral surface 1a with the packing sheet 2, or may cover a part of the roll end surface 1b (for example, before the end of winding of the rug 1). When the end of the packing sheet 2 is inserted between the rolled and overlapped rugs 1 and the packing sheet 2 is also wound together with the rug 1 in that state, one of the packing sheets 2 inserted first. The portion may be exposed from the roll end face 1b, etc.).

After inserting the end of the packing sheet 2 between the rolled and overlapping rugs 1, the packing sheet 2 is also wound together with the rug 1 by rotating the winding core member 21a. Even after the rug 1 has been wound around the rug 1, the packing sheet 2 is further wound around the roll peripheral surface 1a of the rolled rug 1 by further rotating the winding core member 21a to cover the roll peripheral surface 1a. It becomes.
The sheet peripheral portion 22 may have any configuration as long as the roll peripheral surface 1a of the rug 1 is covered by the packing sheet 2 and the roll end surface 1b of the rug 1 is not covered by the packing sheet 2. For example, the sheet peripheral covering portion 22 may have a sheet sending member 22a for feeding out the packing sheet 2 and a sheet cutting member 22b for cutting the packing sheet 2 which has finished covering the roll peripheral surface 1a of the rug 1. ..

Here, the configuration of the packing sheet 2 before covering the roll peripheral surface 1a of the rug 1 is not particularly limited, but a long or long packing sheet 2 is rolled into a roll (packing sheet). It may be a roll 2'), or it may be cut to a size that can cover at least a roll-shaped rug 1.
Hereinafter, the packing sheet 2 will be described as a packing sheet roll 2'in which a long packing sheet 2 is mainly wound in a roll shape.

<Sheet delivery member 22a>
As shown in FIGS.
The sheet sending member 22a may have any configuration as long as the packing sheet 2 can be sent out. For example, the sending roll 22a1 that rotatably supports the packing sheet roll 2'and the packing sheet sent out from the sending roll 22a1. It may have the direction changing material 22a2 which changes the delivery direction of 2.

The delivery roll 22a1 has a support plate 21 ”which is a part of the exterior of the roll winding portion 21 described above, and has a vertical middle portion protruding outward to support both ends thereof.
The delivery roll 22a1 may be a roll that feeds out the packing sheet 2 (such as a roll that is not driven by itself) by the force of winding the packing sheet 2 and the rug 1 together on the roll winding portion 21, but the delivery roll 22a1 itself drives the delivery roll 22a1. It is a drive roll that sends out the packing sheet 2, or even if it is not driven and sent out by itself, it is driven so as to adjust the packing tension (packing tension) applied to the packing sheet 2 when it is wound around the roll winding portion 21. The roll may be the sending roll 22a1. In addition, the packing tension may be adjusted by making it difficult to rotate by a restraining member that holds down the packing sheet roll 2'from the left and right, or by making it easy to rotate.
The length of the packing sheet 2 around which the roll peripheral surface 1a of the rug 1 is wound, the number of rotations of the packing sheet 2 to be wound, and the like may be adjusted by the delivery roll 22a1, but the packing sheet 2 is the roll winding portion 21 ( When it is wound together with the rug 1 by the winding core member 21a), it may be adjusted by the power member 21b of the roll winding portion 21.

The direction changing material 22a2 may have any configuration as long as it changes the sending direction of the packing sheet 2 sent out from the sending roll 22a1, but for example, it may be a substantially rod material or a rotatable roll material. It doesn't matter if there is. Hereinafter, the direction changing material 22a2 will be described as being a substantially rod material.
If the long packing sheet 2 rotatably supported by the sheet delivery member 22a (delivery roll 22a1) described above can cover the roll peripheral surface 1a of the rug 1 via the direction changing material 22a2, the long packing sheet 2 can be covered. The width and the like are not particularly limited, but for example, the width may be substantially the same as or wider than the width of the predetermined folded rug 1, and may be 25 cm or more and 330 cm or less.

<Sheet cutting member 22b>
As shown in FIGS. 1 to 4 and 9, the sheet cutting member 22b may have any configuration as long as it can cut the packing sheet 2 that has completely covered the roll peripheral surface 1a of the rug 1, and may have any configuration. A groove (sheet cutting groove) 22a3 provided in the direction changing material 22a2 (substantially rod material) along the axial direction thereof may be used.
The sheet cutting groove 22a3 is provided on the outer side of the direction changing material 22a2 (the side in contact with the packing sheet 2 to be sent out), and the roll peripheral surface 1a of the roll-shaped rug 1 is formed by the packing sheet 2. When the covering is finished, the packing sheet 2 is cut along the sheet cutting groove 22a3 with a cutting tool such as a cutter.

It should be noted that the cutting tool may be placed along the sheet cutting groove 22a3 by an operator or by an apparatus. In this case, the direction changing material 22a2 itself, which is a substantially bar material, is also a sheet cutting member 22b. I can say.
In addition, the sheet cutting member 22b may cut the packing sheet 2 which does not have the sheet cutting groove 22a3 and has finished covering the roll peripheral surface 1a of the rug 1 with a device having a cutting tool.

<Transport unit 23>
As shown in FIG. 9, the transport unit 23 is a portion that transports the predetermined folded rug 1 to the compression transport unit 24 described later.

Further, the length of the endless belt 23a in a plan view is not particularly limited, but may be, for example, substantially the same as or longer than the length in a plan view of the predetermined folded rug 1.

The number of rolls 23b depends on the distance to be conveyed, but at least one of the rolls 23b arranged at both ends of the endless belt 23a is a drive roll that is driven to rotate by itself, and another roll 23b is provided between the rolls 23b at both ends. It may have a roll (such as a carrier roll that is not driven by itself) 23b.

This is the part to be transported.
The compression conveyor 24 may have any configuration as long as it can convey the rug 1 folded and folded to the holding portion 25 while compressing it. For example, the compression conveyor 24 is provided as a pair of upper and lower belt conveyors (upper belt conveyor). 24 ′ and the lower belt conveyor 24 ″) and a pressing member (not shown) that presses at least one of these belt conveyors 24 ′ and 24 ″ to the other side may be provided.

The upper and lower belt conveyors 24'and 24 "have the endless belts 24a'and 24a" and the rolls 24b'and 24b "that rotate these endless belts 24a' and 24a", respectively, as in the above-described transport section 23. You may have.
The size (width, length, etc.) of these endless belts 24a', 24a "in a plan view is also not particularly limited, but for example, the width is abbreviated as the width in a plan view of a predetermined folded rug 1. It may be the same or wider, and may be 25 cm or more and 330 cm or less.

The length of the endless belts 24a', 24a "in the plan view is also not particularly limited, but may be substantially the same as or longer than the length in the plan view of the predetermined folded rug 1.
The number of rolls 24b', 24b "depends on the distance to be conveyed, but at least one of the rolls 24b', 24b" arranged at both ends of the endless belts 24a', 24a "is a drive roll that is driven to rotate by itself. There may be another roll (such as a carrier roll that is not driven by itself) 24b', 24b "between the rolls 24b', 24b" at both ends.

The pressing member may have any configuration as long as it can press at least one of the upper and lower belt conveyors 24'and 24 "to the other side, and may be, for example, an air cylinder or a hydraulic cylinder.
The pressing member presses one belt conveyor (for example, upper belt conveyor 24') toward the other belt conveyor (for example, lower belt conveyor 24'), or both press toward each other (upper belt conveyor 24'). At the same time as pressing the lower belt conveyor 24 "to the side of the upper belt conveyor 24'), it may be used.

In addition, the compression transfer unit 24 is not the upper and lower belt conveyors 24', 24 ", but is conveyed along the rail while the rug 1 conveyed from the above-mentioned transfer unit 23 and folded a predetermined number of times is compressed in the thickness direction thereof. It may be a movable slider, a robot arm, or the like.
Further, it can be said that the speed (conveying speed) of transporting the rug 1 folded a predetermined number of times while compressing it can be adjusted by the drive rolls 24b', 24b "driven by the compression transporting unit 24.

<Holding part 25>
