Description

[Technical field]

[0001] The present invention relates to a binding assistant device used in a binding machine that binds a plurality of folded pieces of cloth, a binding machine having the binding assistant device, and a linen system including them. [Background technology]

[0002] The linen products handled by the so-called linen supply industry, which are used by clients such as hotels and hospitals, include, for example, sheets, bed covers, large and small towels, and various other types of fabric. Linen supply businesses collect these fabrics from their clients, wash, iron, fold, and then deliver them to the clients in a repeated process. That is, they fold towels, bath towels, and other fabrics into a specified shape such as in half, in thirds, in French folds, or in quarters, stack multiple folded fabrics, and tie them together with a string by a binding machine for each specified number of sheets before delivering them to the above-mentioned clients.

[0003] Regarding the binding machine used in the final process, for example, Japanese Utility Model Application Publication No. 5-54210 discloses a binding machine that "straddles the gap between a fixed table and an auxiliary table, and by activating a clutch, strings and binds the object to be bound placed in the binding position, characterized in that a limit switch is installed on the fixed table, and when the object to be bound is placed in the binding position, the object hits the limit switch, activating the clutch."

[0004] Thus, since the binding machine used in the final process in the linen supply industry is a general-purpose product, it is not necessarily suitable for binding multiple layers of flexible fabrics. In other words, a general-purpose binding machine is used for binding relatively hard objects such as books and papers. However, the objects to be bound in the linen supply industry are multiple layers of fabrics folded into a specific shape, and when a string is tied around the multiple layers of fabrics, the multiple layers of fabrics are deformed, so the tension during stringing is not stable. For this reason, the string may not be tied properly, the string may be tied too tightly, and the multiple layers of fabrics may become sagging, resulting in poor binding, or conversely, the knot of the string may come undone, or the multiple layers of fabrics may fall off the tied string.

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 5-54210 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0006] Therefore, the present invention has been made with attention to the above-mentioned points, and its object is to provide a binding assistance device that minimizes binding failures when binding multiple stacked pieces of fabric, even with a conventional binding machine, a binding machine equipped with said device, and a linen system. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the inventor has conducted research and development and developed a binding auxiliary device of a first aspect, which has a pressing section that presses multiple stacked pieces of cloth when the multiple stacked pieces of cloth are transported to a binding machine for stringing, and a binding auxiliary member used to bind the cloth pressed by the pressing section, and in which the pressing section presses the multiple stacked pieces of cloth, and the string engages with the binding auxiliary member when the multiple stacked pieces of cloth are stringed by the binding machine.

[0008] In addition, the second aspect of the binding assist device is such that, in the first aspect, the binding assist member has a rod-shaped member with which the string engages and a drive unit that attaches the rod-shaped member so that it can be protruded, and when the string is fastened by the binding machine, the string engages with the rod-shaped member in the binding assist member.

[0009] In addition, the bundling assist device of a third aspect is the bundling assist device of the first or second aspect, wherein the bundling assist member is attached to the pressing portion.

[0010] In addition, the binding assist device of a fourth aspect is the same as that of the third aspect, in that the pressing portion further has a first roller, a second roller, and a connecting portion connecting the first roller and the second roller, and the binding assist member is attached to the connecting portion.

[0011] In addition, the binding assist device of a fifth aspect is similar to the first aspect, in that the pressing portion moves up and down to press multiple stacked pieces of cloth, and the binding assist member follows the up and down movement of the pressing portion.

[0012] A sixth aspect of the present invention relates to a binding machine having the binding auxiliary device according to the first aspect to the fifth aspect.

[0013] A linen system according to a seventh aspect has at least a folding device for stacking a plurality of folded pieces of cloth, a binding assistant device according to the first to fifth aspects, and a binding machine. Effect of the Invention

[0014] Because the present invention is constructed and functions as described above, it is possible to provide a binding auxiliary device that minimizes binding failures when binding multiple stacked pieces of fabric, even when using a conventional binding machine, a binding auxiliary device, a binding machine having the same, and a linen system.

[0016] The bundling assist device 10 of the first embodiment will be described below with reference to the illustrated embodiment. The bundling assist device 10 of the first embodiment can be arranged in a bundling machine 300. The bundling machine 300 will be briefly described below. The bundling machine 300 is a known device, and has a cord guide arm 310 that rotates around a circular track K when viewed from the front, and rotates to wrap the cord R around a stack of fabrics 100 (hereinafter, sometimes referred to as stacked fabrics 100) made of multiple pieces of fabric folded into a predetermined shape such as folded in two, folded in three, folded in French, folded in four, etc., and has a cord pressing button 330 that positions the cord R at a predetermined position, a cord pressing member 340 that presses the cord R in a predetermined direction L, and a bundling mechanism 350 that ties the cord R (see FIG. 8). The bundling machine 300 has an auxiliary conveyor 360, and is arranged flush with the feed conveyor 201 (see FIGS. 1, 2, and 3). The stacked fabrics 100 are transported from the conveyor 400 through the feed conveyor 201 to the auxiliary conveyor 360. The conveyor 400 and the feed conveyor 201 will be described later.

[0017] The binding machine 300 also has a main conveyor 370 and a transfer plate 301 that fills the gap between the main conveyor 370 and the auxiliary conveyor 360. The transfer plate 301 is attached to the auxiliary conveyor 360 and is attached in a state separated from the main conveyor 370. In this way, the transfer plate 301 allows the fabric 100 to be smoothly transported from the main conveyor 370 to the auxiliary conveyor 360 (see Figs. 1, 2, and 3). In addition, a track K on which the string guide arm 310 revolves is located between the auxiliary conveyor 360 and the main conveyor 370 (see Figs. 1 and 8). The string R is guided along the track K on which the string guide arm 310 revolves, so that the string R is wound around the items to be bound, and items placed within the track K can be bound. This is the same as in the conventional binding machine.

[0018] The binding assistance device 10 of the first embodiment is used when binding a pile of cloth 100, which is made up of multiple pieces of cloth folded into a predetermined shape and fed from a feed conveyor 201, using a binding machine 300, and has a pressing section 20 positioned above the feed conveyor 201, and a binding assistance member 30.

[0019] The pressing unit 20 is disposed above the feed conveyor 201 and the auxiliary conveyor 360, and is moved from above to below by the vertical movement unit 250 described later in order to press the stacked fabrics 100. The pressing unit 20 has a first roller 21 and a second roller 22 rotated by a driving unit of a motor (not shown), and a belt unit 23 consisting of a plurality of belts is disposed so as to be wound around the first roller 21 and the second roller 22. The belt unit 23 rotates by driving the first roller 21 and the second roller 22. This prevents the feed conveyor 201 from interfering with the conveyance of the stacked fabrics 100, and prevents the stacked fabrics 100 from turning over. In FIG. 1, the pressing unit 20 shown by the solid line represents a state in which it is positioned at the top, and the pressing unit 20 shown by the dashed line represents a state in which it is positioned at the bottom.

[0020] As described above, the pressing unit 20 is arranged so that the belt portion 23 consisting of multiple belts is wrapped around it, and is essentially a conveyor in that the belt portion 23 consisting of multiple belts is arranged so that it is wrapped around the first roller 21 and the second roller 22.Therefore, by moving the pressing unit 20 downward, when the multiple belts 23 press the stacked multiple pieces of fabric 100, the multiple belt portions 23 flex, and an appropriate pressing force can be obtained (see Figures 4A and B).

[0021] The bundling auxiliary member 30 in the bundling auxiliary device 10 of the first embodiment is disposed in the pressing section 20. Specifically, the bundling auxiliary member 30 is disposed in the connecting section 24 that connects the first roller 21 and the second roller 22. The bundling auxiliary member 30 has a drive section 31 and a rod-shaped member 33, the drive section 31 is attached to the connecting section 24, and the drive section 31 is configured to cause the rod-shaped member 33 to protrude in the direction (rearward R) in which the bundling machine 300 is disposed. The drive section 31 is preferably an air cylinder, and although not shown, an electric cylinder or a solenoid is also preferable.

[0022] The pressing unit 20 is provided with a sensor 26 for identifying the stacked fabrics 100. The sensor 26 detects the stacked fabrics 100 from the underside of the pressing unit 20, and detects the upper surface of the stacked fabrics 100 when the pressing unit 20 descends (see FIG. 4B). The pressing unit 20 is stopped at a position further lowered from the detected position of the stacked fabrics 100 at an arbitrarily set position, thereby pressing the stacked fabrics 100. That is, the pressing unit 20 located at the top descends, and the lowered pressing unit 20' is positioned so as to slightly crush the stacked fabrics 100 (see FIG. 6).

[0023] The pressing unit 20 is moved up and down by the vertical movement unit 250. The vertical movement unit 250 has a motor 251 for driving, a gear box 252 rotated by the motor 251, the gear boxes 252, 252, a shaft 253 connecting the gear boxes 252, 252, and gear shafts 254, 254 meshing with the gear boxes 252, 252. Specifically, the motor 251 rotates, and the gear shafts 254, 254 meshing with the gears rotate, so that the gear shafts 254, 254 move up and down, and the pressing unit 20 connected to the gear shafts 254, 254 moves up and down (see Figs. 5A, 5B, 5C, etc.). The pressing unit 20 also has an upper limit sensor 260 and a lower limit sensor 261 that control the upper and lower limits when the pressing unit 20 moves up and down in this way.

[0024] Next, the operation of the bundling auxiliary device 10 of the first embodiment configured as described above will be described. When the feed conveyor 201 transports the stacked fabric 100 toward the bundling machine 300 (rear R) and stops at a predetermined position, the pressing unit 20 is placed on the stacked fabric 100. In this state, the pressing unit 20 is lowered by the vertical movement unit 250. As a result, the stacked fabric 100 is pressed, compressing the fabric 100 (see FIG. 7A).

[0025] By the above-mentioned transport, the stacked pieces of fabric 100 are arranged from the conveyor 201 onto the auxiliary conveyor 360, the transfer plate 301, and the main conveyor 370. At this time, a predetermined portion 101 of the stacked pieces of fabric 100 is arranged within the track K on which the string guide arm 310 rotates. After that, the rod-shaped member 33 of the bundling assistant member 30 is protruded by the drive unit 31 in the direction of the bundling machine 300 (rear R).

[0026] As described above, the fabric 100 compressed by the pressing unit 20 is placed on the transfer plate 301. In this state, the string guide arm 310 in the binding machine 300 rotates along the trajectory K along which the string guide arm 310 rotates while carrying the string R (see FIG. 7B). As shown in FIGS. 8A and 8B, in a front view of the binding machine 300, the string R is wound around the fabric 100, and the wound string R is arranged so as to contact the right lower part 101 and the right upper part 102 of the fabric 100, and does not contact the left upper part 103 and the left lower part 104 of the fabric 100, but engages with the rod-shaped member 33 of the binding assistant member 30 instead of the left upper part 103 of the fabric 100. Also, instead of the lower left part 104, when the string pressing button 330 is engaged and the string R is pressed in a predetermined direction by the string pressing member 340 (see the arrows in Figures 8A and 8B), the string R is pressed and both ends of the string R are tied together by the binding mechanism 350 that ties together the pressed string R (see Figure 9A).

[0027] At this time, as described above, the first tying string R of the cloth 100 is arranged so that the string R contacts the right lower part 101 and the right upper part 102 of the cloth 100 when viewed from the front of the binding machine 300, and engages with the rod-shaped member 33 and the string pressing button 330 of the binding assistant member 30. At this time, since the rod-shaped member 33 and the string pressing button 330 are positioned, the tension of the string R between the two points of the rod-shaped member 33 and the string pressing button 330 is small, and poor binding is prevented as much as possible (see Figs. 8A and 8B). In this regard, in a state where the rod-shaped member 33 is not present, the tension of the string R between the two points of the cloth 100 and the string pressing button 330 varies greatly due to the cloth 100 being crushed, and there is a high possibility of poor binding. Therefore, the risk of poor binding of the cloth 100 once tied can be reduced as much as possible.

[0028] Then, the rod-shaped member 33 of the bundling auxiliary member 30 is retracted in the opposite direction (forward F) to the bundling machine 300 by the driving unit 31. Then, the pressing unit 20 is raised by the vertical moving unit 250, and the stacked fabric 100 is transported toward the bundling machine 300 by the feed conveyor 201 again. At this time, the fabric 100 is bound together with the transfer plate 301 by the string R, and the stacked fabric 100 is transported toward the bundling machine 300. At this time, as described above, since the transfer plate 301 is attached to the auxiliary conveyor 360 in a state separated from the main conveyor 370, the string R is removed from the transfer plate 301 by the transport (see FIG. 9A). By arranging the transfer plate 301 in this way, the gap between the auxiliary conveyor 360 and the main conveyor 370 is filled, and the transfer plate 301 is bound together with the string R, so that the soft fabric 100 can be bound more reliably.

[0029] When the fabric 100 stops at the second position 102, which is the second predetermined position, the pressing unit 20 is placed on the stacked fabric 100. In this state, the pressing unit 20 is lowered again by the vertical movement unit 250 (see FIG. 9B). This presses the stacked fabric 100 again, compressing the fabric 100. After that, the binding machine 300 rotates the string guide arm 310 of the binding machine 300 along the track K while carrying the string R again at the second position 102 of the fabric 100 in the same manner as described above. This binds the fabric 100 with the string R in the same manner as described above (see FIGS. 10A and 10B). The bound fabric 100 then moves on the main conveyor 370. It is then shipped to the customer.

[0030] At this time, as for the string R2 at the second position 102 on the cloth 100, the tension of the string R2 between the two points, the rod-shaped member 33 and the string pressing button 330, fluctuates little, as described above, and poor binding is prevented as much as possible. In this regard, in a state in which the rod-shaped member 33 is not present, the tension of the string R2 between the two points, the cloth 100 and the string pressing button 330, fluctuates a lot due to the cloth 100 being crushed, and there is a high possibility of poor binding. Therefore, as described above, the risk of poor binding of the cloth 100 once tied can be reduced as much as possible (see FIGS. 8A and B).

[0031] The bundling assistant device 12 of the second embodiment is used when bundling a plurality of stacked pieces of cloth folded into a predetermined shape sent out from a feed conveyor 201 in a folding device 200 with a bundling machine 300, and has a second pressing unit 60 and a second bundling assistant member 70 disposed on the feed conveyor 201. The bundling assistant device 10 of the first embodiment differs from the bundling assistant device 12 of the second embodiment in that the second bundling assistant member 70 is configured as a separate body from the second pressing unit 60. The second pressing unit 60 has a similar configuration in which it moves up and down by a vertical movement unit 250 (see FIG. 11).

[0032] The second pressing unit 60 is similar to the binding machine 10 of the first embodiment in that a belt unit 63 consisting of a plurality of belts is arranged on a first roller 61 and a second roller 62 that are rotated by a driving unit of a motor (not shown). The second pressing unit 60 presses the stacked fabrics 100 downward, and has a vertical movement unit 250 for moving the fabrics 100 upward or downward. The second pressing unit 60 also has a second connecting unit 64 that connects the first roller 61 and the second roller 62. The vertical movement unit 250 described in the first embodiment has the same configuration as the vertical movement unit 250 of the binding auxiliary device 12 of the second embodiment. The vertical movement unit 250 moves the second pressing unit 60 up and down (see FIG. 11). The vertical movement unit 250 is omitted in FIGS. 12 to 14.

[0033] The second bundling auxiliary member 70 has a table portion 72 arranged so as to be movable up and down by an electric actuator 71. The second bundling auxiliary member 70 also has a second driving portion 81 attached to the table portion 72, and a second rod-shaped member 83 is attached to the second driving portion 81 so as to be capable of appearing and disappearing. As described above, the second pressing portion 60 is attached to the vertical movement portion 250, and the electric actuator 71 is arranged so as to synchronize with the movement of the second pressing portion 60 which moves up and down by the vertical movement portion 250. That is, the magnet portion 65, which is a magnet, is arranged in the second connecting portion 64, and a magnetic detection switch 74 which detects the magnetic force of the magnet portion 65 is arranged in the table 72. The second driving portion 81 is preferably an air cylinder. Although not shown, an electric cylinder or a solenoid is also preferable.

[0034] When the upper second pressing section 60' is lowered by the vertical movement section 250 similar to that of the first embodiment in order to press the cloth 100, the table section 72 arranged to be movable up and down by the electric actuator 71 also descends, and the magnetic force of the magnet section 65 is detected by the magnetic detection switch 74, so that the descent of the table section 72 stops. In this way, the table section 72 having the second rod-shaped member 83 is configured to be synchronized with the vertical movement of the second pressing section 60. Therefore, the second pressing section 60 moves up and down to press the cloth 100, and the bundling assistant member 70 follows the vertical movement of the second pressing section 60.

[0035] Next, the operation of the bundling auxiliary device 12 of the second embodiment configured as described above will be described. When the feed conveyor 201 conveys the stacked fabric 100 toward the bundling machine 300 and stops at a predetermined position, the second pressing unit 60 is placed on the stacked fabric 100. In this state, the second pressing unit 60 is lowered by the vertical movement unit 250. This presses the stacked fabric 100, compressing the fabric 100. At that time, as described above, the table unit 72 arranged to be vertically movable by the electric actuator 71 also descends, and the magnetic force of the magnet unit 65 is detected by the magnetic detection switch 74, so that the descent of the table unit 72 is stopped and the table unit 72 is placed near the second pressing unit 60.

[0036] By the above-mentioned conveyance, a predetermined portion 101 of the stacked multiple pieces of fabric 100 is placed in the track K on which the string guide arm 310, on which the handover plate 301 is placed, rotates. Then, the second rod-shaped member 73 of the second bundling auxiliary member 70 is protruded toward the bundling machine 300 by the second drive unit 81.

[0037] The cloth 100 compressed by the second pressing unit 60 is arranged so as to overhang the cross plate 301. In this state, the string guide arm 310 in the binding machine 300 rotates with the string R. As shown in FIG. 14, in a front view of the binding machine 300, the string R is arranged so as to contact the right lower portion 101 and the right upper portion 102 of the cloth 100, but does not contact the left upper portion 103 and the left lower portion 104 of the cloth 100, and engages with the rod-shaped member 33 of the binding assistant member 30 instead of the left upper portion 103 of the cloth 100. Also, when the string R engages with the string pressing button 330 instead of the left lower portion 104 and is pressed in a predetermined direction by the string pressing member 340 (see the arrow in FIG. 14), both ends of the string R are tied by the binding mechanism 350 that ties the string R.

[0038] Thereafter, the second rod-shaped member 83 of the second bundling auxiliary member 70 is retracted in the direction opposite to the bundling machine 300 by the second driving unit 81. In other words, it is returned to its original position. Thereafter, the second pressing unit 60 rises, and the table unit 72 follows the movement of the second pressing unit 60, and the table unit 72 is placed in the vicinity of the second pressing unit 60.

[0039] At this time, as described above, the first tying string R of the fabric 100 is arranged so that the string R contacts the lower right portion 101 and the upper right portion 102 of the fabric 100 when viewed from the front of the binding machine 300 (FIG. 14), and engages with the rod-shaped member 33 and the string pressing button 330 of the binding assistant member 30. At this time, since the positions of the second rod-shaped member 73 and the string pressing button 330 are fixed, their positions do not fluctuate even depending on how the fabric 100 is crushed, and poor binding is prevented as much as possible. The same is true for the string that binds the fabric 100 at the second position, not shown.

[0040] In the linen supply business, sheets, bed covers, towels of various sizes, and other fabrics used by clients such as hotels and hospitals are collected, washed, and ironed with an ironer (not shown), and then the fabrics are folded into a predetermined shape by a folding device 200 and stacked in predetermined numbers. The stacked fabrics 100 are transported by a conveyor 400, and shipped from a feed conveyor 201 through a linen system 500 having the above-mentioned bundling assistant device 10 or the bundling assistant device 12 of the second embodiment and a bundling machine 300. In this way, the linen system 500 has a folding device 200 that stacks multiple pieces of fabric folded into a predetermined shape such as folded in half, folded in three, or folded in French, the bundling assistant device 10 of the first embodiment or the bundling assistant device 12 of the second embodiment, and the bundling machine 300. Additionally, the linen system 500 may further include a conveyor 400 and a feed conveyor 201 (see FIGS. 15 and 16). [Explanation of symbols]
