The suction portion 22 is provided at the tip of the arm portion 21 and is configured to be able to adsorb the glass fiber packed body 2a by suction with air.

[0033] As shown in FIGS. 1, 3 to 6, the transfer device 30 is an embodiment of the driving means according to the present invention. The transfer device 30 enables the lid device 40 (the lid member 42 of the lid device 40) to move horizontally between an "arrangement position" located above a plurality of glass fiber packed bodies 2a and a "retreat position" spaced apart horizontally from the arrangement position. The transfer device 30 includes a pair of belt conveyors 31, a pair of rails 32, and a plurality of blocks 33. The belt conveyor 31 is configured such that an endless belt 31a is suspended from two pulleys 31b. The pair of belt conveyors 31 are arranged side by side in a direction orthogonal to the direction in which the belt 31a extends and are close to each other. The belt conveyor 31 horizontally moves the lid device 40 between the "arrangement position" and the "retreat position". The belt conveyor 31 stabilizes the horizontal movement of the lid device 40 between the "arrangement position" and the "retreat position" by the rails 32 and the blocks 33. The rails 32 are linearly configured. The pair of rails 32 are arranged above and between the pair of belts 31a. The pair of rails 32 are arranged side by side in a direction orthogonal to the direction in which the rails 32 extend. The blocks 33 are provided on the rails 32 and are configured to be movable along the rails 32. A base plate 41 of the lid device 40 described later is fixed to the upper surface of the block 33, and the block 33 and the lid device 40 are configured to be integrally movable along the rails 32. When the belt conveyor 31 is driven, the transfer device 30 horizontally moves the lid device 40 fixed to the block 33 along the rails 32 between the "arrangement position" and the "retreat position".

[0034] The lid device 40 includes a base plate 41, a lid member 42, a lifting device 43, and a suction pad 45. The base plate 41 is a trapezoidal member having a substantially rectangular shape in plan view. The lid member 42 is an embodiment of the lid according to the present invention. The lid member 42 is a plate-like member having a substantially rectangular shape in plan view, and the lid member 42 is disposed below the base plate 41. The lid member 42 is configured to be disposed above a plurality of glass fiber packed bodies 2a. The lid member 42 has a plurality of groove portions 44 on its lower surface. The groove portions 44 are substantially linear grooves extending in directions parallel and orthogonal to the moving direction between the "arrangement position" and the "retreat position" of the lid device 40, and through which the tightening member is inserted when tightening the plurality of glass fiber packed bodies 2a. The lid member 42 has a plurality of suction pads 45 on its lower surface, and is configured to be able to hold the top plate 3 by the suction pads 45. The suction pad 45 is an embodiment of the suction means according to the present invention. The suction pad 45 is configured to be able to suck the top plate 3 described later by suction with air. The suction pad 45 is provided so as to protrude downward from the lower surface of the lid member 42. The suction pad 45 is configured to be movable in the vertical direction with respect to the lid member 42. A spring member (not shown) is provided between the suction pad 45 and the lid member 42, and the suction pad 45 is biased downward by the elastic force of the spring member. The spring member buffers the impact when the suction pad 45 sucks the top plate 3.

[0035] The lifting device 43 is configured such that a fixed portion is provided on the base plate 41 and a rod-shaped moving portion extends downward from the fixed portion. The lower end portion of the moving portion of the lifting device 43 is fixed to the upper surface of the lid member 42. The lifting device 43 is configured to be able to raise and lower the lid member 42 with respect to the base plate 41 by shortening or lengthening the length of the moving portion extending from the fixed portion. Note that the configuration of the lifting device 43 is not limited to such a configuration, and any configuration may be used as long as it is configured to be able to raise and lower the lid member 42 with respect to the base plate 41.

[0036] The compression device 50 is an embodiment of the pressing means according to the present invention. The compression device 50 compresses the plurality of glass fiber packed bodies 2a together with the lid member 42 of the lid device 40. The compression device 50 includes a frame body 51, a mounting table 52, a lifter 53, a first position detection device 54, and a second position detection device 55. The frame body 51 is configured such that a plurality of metal struts are combined to have a bottom and side portions and an upper opening, and a predetermined space is formed within the frame body 51. In the space within the frame body 51, a plurality of glass fiber packed bodies 2a are configured to be vertically placed. A mounting table 52 and a lifter 53 are arranged at the lower part within the plurality of frame bodies 51. The mounting table 52 is an embodiment of the stage according to the present invention. The mounting table 52 is configured to be able to mount a plurality of glass fiber packed bodies 2a. A pallet 4 is arranged on the upper surface of the mounting table 52, and a plurality of glass fiber packed bodies 2a are arranged on the upper surface of the pallet 4 so as to overlap in the vertical direction. Above the mounting table 52 of the compression device 50 is configured as the "arrangement position" of the lid member 42 of the lid device 40. The lifter 53 is an embodiment of the driving means according to the present invention. The lifter 53 is arranged below the mounting table 52. The lifter 53 enables the mounting table 52 to move up and down. The compression device 50 compresses a plurality of glass fiber packed bodies 2a between the mounting table 52 and the lid member 42 of the lid device 40 by raising the mounting table 52 by the lifter 53.

[0037] The first position detection device 54 of the compression device 50 is an embodiment of the detection sensor according to the present invention. The first position detection device 54 detects the vertical position of the mounting table 52. The first detection device 54 is arranged below the mounting table 52 at the lower part within the frame body 51. The first detection device 54 is a distance sensor and is configured to be able to detect the distance to the mounting table 52. Information regarding the vertical position of the mounting table 52 detected by the first detection device 54 is transmitted to the control device 10. The first detection device 54 is not limited to such a configuration, and may be other configurations as long as it can detect the vertical position of the mounting table 52. For example, it may be arranged on the mounting table 52, or may be arranged on the side portion of the frame body 51. The second position detection device 55 is a photoelectric object sensor that detects the presence or absence of the glass fiber packed body 2a placed on the mounting table 52 at a predetermined vertical position. The second detection device 55 is disposed on the upper side of the frame body 51. The second detection device 55 is disposed at a height at which the glass fiber packed body 2a is placed on the mounting table 52 by the robot arm 20. Information regarding the presence or absence of the glass fiber packed body 2a placed on the mounting table 52 detected by the second detection device 55 is transmitted to the control device 10. The second detection device 55 is not limited to such a configuration, and any other configuration may be used as long as it can detect the presence or absence of the glass fiber packed body 2a placed on the mounting table 52 at a predetermined vertical position.

[0038] [Method for manufacturing glass fiber packed body] Next, a method for manufacturing a glass fiber packed body using the manufacturing apparatus 1 for a glass fiber packed body will be described. The method for manufacturing a glass fiber packed body involves compressing a plurality of glass fiber packed bodies 2a by a compression device 50. As shown in FIG. 7, the method for manufacturing a glass fiber packed body includes a placement step S1, a lid placement step S2, a top plate placement step S3, a compression step S4, and a tightening step S5. The manufacturing apparatus 1 for a glass fiber packed body is configured to automatically perform an operation of compressing a plurality of glass fiber packed bodies 2a by controlling operations of the robot arm 20, the transfer device 30, the lid device 40, the compression device 50, etc. by the control device 10 to execute the placement step S1, the lid placement step S2, the top plate placement step S3, the compression step S4, and the tightening step S5.

[0039] First, as shown in FIG. 4 or FIG. 7, a placement step S1 of placing a plurality of glass fiber packed bodies 2a on the mounting table 52 of the compression device 50 is performed (step S1). In the placement step S1, the control device 10 drives the belt conveyor 31 of the transfer device 30 to move the lid device 40 to the "retracted position", and then drives the robot arm 20 to place the glass fiber packed bodies 2a one by one on the mounting table 52 of the compression device 50. At this time, after the pallet 4 is placed upward on the mounting table 52 of the compression device 50, the plurality of glass fiber packed bodies 2a are placed so as to overlap vertically on the pallet 4. When the glass fiber packed bodies 2a are placed so as to overlap vertically by the preset number of stages, the control device 10 stops the operation of placing the glass fiber packed bodies 2a on the mounting table 52 of the compression device 50 by the robot arm 20. Also at this time, every time a predetermined number of glass fiber packed bodies 2a are placed on the mounting table 52 of the compression device 50, the control device 10 drives the lifter 53 of the compression device 50 to move the mounting table 52 downward by the thickness in the vertical direction of the placed glass fiber packed bodies 2a. When the glass fiber packed body 2a located at the uppermost position placed on the mounting table 52 is detected by the second position detection device 55 of the compression device 50, the control device 10 continues the operation of driving the lifter 53 of the compression device 50 to move the mounting table 52 downward. When the state becomes such that the glass fiber packed body 2a located at the uppermost position placed on the mounting table 52 is not detected by the second position detection device 55 of the compression device 50, the control device 10 stops the driving of the lifter 53 of the compression device 50 and stops the operation of moving the mounting table 52 downward. By moving the mounting table 52 downward every time a predetermined number of glass fiber packed bodies 2a are placed on the mounting table 52 of the compression device 50 in this way, the height when the glass fiber packed bodies 2a are placed on the mounting table 52 of the compression device 50 by the robot arm 20 is made substantially constant. Note that instead of the configuration for detecting the presence or absence of the glass fiber packed body 2a located at the uppermost position placed on the mounting table 52 by the second position detection device 55 of the compression device 50, a configuration may be adopted in which the distance for moving the mounting table 52 downward when a predetermined number of glass fiber packed bodies 2a are placed on the mounting table 52 of the compression device 50 is preset. After placing a plurality of glass fiber packed bodies 2a on the mounting table 52 of the compression device 50 in the mounting process S1, the process proceeds to steps S2 and S3.

[0040] Next, as shown in FIG. 7, a lid body placement step S2 of placing the lid member 42 of the lid body device 40 above the plurality of glass fiber packed bodies 2a is performed (step S2), and at the same time, a top plate placement step S3 of placing the top plate 3 on the plurality of glass fiber packed bodies 2a placed on the mounting table 52 of the compression device 50 is performed (step S3). At this time, in the lid body placement step S2 and the top plate placement step S3, first, at the "retracted position" of the lid body device 40, the control device 10 drives the lifting device 43 of the lid body device 40 to lower the lid member 42 with respect to the base plate 41, and the top plate 3 disposed at the top plate placement portion 60 is adsorbed by the adsorption pad 45. Next, the control device 10 drives the lifting device 43 of the lid body device 40 to raise the lid member 42 and the top plate 3 adsorbed by the adsorption pad 45 with respect to the base plate 41 so as to be positioned above the frame body 51 of the compression device 50 (see FIG. 5). In such a state, the control device 10 drives the belt conveyor 31 of the transfer device 30 to horizontally move the lid body device 40 and move it to the "placement position" of the lid body device 40 (see FIG. 6). At the "placement position" of the lid body device 40, the control device 10 drives the lifting device 43 of the lid body device 40 to lower the lid member 42 with respect to the base plate 41, releases the adsorption of the top plate 3 by the adsorption pad 45, and places the top plate 3 on the plurality of glass fiber packed bodies 2a placed on the mounting table 52 of the compression device 50 (see FIG. 1). That is, the top plate 3 is held by the adsorption pad 45 disposed on the lower surface of the lid member 42 of the lid body device 40, and after being moved to a predetermined position above the plurality of glass fiber packed bodies 2a together with the lid member 42, it is placed above the plurality of glass fiber packed bodies 2a. Instead of performing the lid placement step S2 of placing a lid on the upper side of the plurality of glass fiber packed bodies 2a and simultaneously performing the top plate placement step S3 of placing the top plate 3 on the plurality of glass fiber packed bodies 2a placed on the mounting table 52, after performing the lid placement step S2 of placing a lid on the upper side of the plurality of glass fiber packed bodies 2a, a configuration may be adopted in which the top plate placement step S3 of placing the top plate 3 on the plurality of glass fiber packed bodies 2a placed on the mounting table 52 is performed. Also, a configuration may be adopted in which after performing the top plate placement step S3 of placing the top plate 3 on the plurality of glass fiber packed bodies 2a placed on the mounting table 52, the lid placement step S2 of placing a lid on the upper side of the plurality of glass fiber packed bodies 2a is performed. In the lid placement step S2, a lid is placed on the upper side of the plurality of glass fiber packed bodies 2a. After placing the top plate 3 on the plurality of glass fiber packed bodies 2a placed on the mounting table 52 in the top plate placement step S3, the process proceeds to step S4.

[0041] Next, as shown in FIG. 1 or FIG. 7, a compression step S4 of compressing the plurality of glass fiber packed bodies 2a between the mounting table 52 and the lid member 42 of the lid device 40 is performed by raising the mounting table 52 of the compression device 50 (step S4). In the compression step S4, the control device 10 drives the lifter 53 of the compression device 50 to raise the mounting table 52, thereby compressing a plurality of glass fiber packed bodies 2a in the vertical direction between the mounting table 52 and the lid member 42 of the lid device 40. At this time, the control device 10 compresses a plurality of glass fiber packed bodies 2a between the mounting table 52 and the lid member 42 of the lid device 40 by raising the mounting table 52 of the compression device 50 to a preset rising position. The rising position of the mounting table 52 when compressing the glass fiber packed body 2a in the vertical direction is stored in advance in the control device 10. When the vertical position of the mounting table 52 detected by the first position detection device 54 of the compression device 50 reaches the preset rising position, the control device 10 stops driving the lifter 53 of the compression device 50 and stops the operation of moving the mounting table 52 upward. Note that the above-mentioned "rising position" can be determined based on data obtained in advance by performing a compression test on the glass fiber packed body 2a to find out how much compression can be achieved without damaging the glass fiber packed body 2a. After compressing a plurality of glass fiber packed bodies 2a between the mounting table 52 of the compression device 50 and the lid member 42 of the lid device 40 in the compression step S4, the process proceeds to step S5.

[0042] Next, as shown in FIG. 7, a tightening step S5 is performed in which a plurality of glass fiber packed bodies 2a are integrally tightened by a tightening member. In the tightening step S5, a plurality of glass fiber packed bodies 2a arranged overlapping in the vertical direction are automatically integrally tightened by a predetermined tightening device using a tightening member made of a predetermined string material. At this time, the pallet 4 and the top plate 3 are integrally tightened together with a plurality of glass fiber packed bodies 2a so that the tightening member is wound around below the pallet 4 (or an opening formed in the side surface of the pallet 4) and above the top plate 3 (inside the groove portion 44 of the lid device 40). Note that instead of automatically tightening using a predetermined tightening device, a configuration in which a plurality of glass fiber packed bodies 2a are manually tightened may be adopted. As described above, a series of operations are performed in the glass fiber package manufacturing apparatus 1 to compress a plurality of glass fiber packed bodies 2a by the compression device 50.

[0043] As described above, in the placing step 1, since the plurality of glass fiber packed bodies 2a are placed on the pallet 4 after the pallet 4 is placed on the placing table 52 of the compressing device 50, the glass fiber package 2 can be moved together with the pallet 4, and the handling of the glass fiber package 2 becomes easy.

[0044] As described above, in the lid body placing step 2, since the lid member 42 of the lid body device 40 is provided so as to be horizontally movable between the "placing position" located above the plurality of glass fiber packed bodies 2a and the "retreat position" spaced apart in the horizontal direction from the placing position, compared with the configuration in which both the "placing position" and the "retreat position" of the lid body device 40 are provided above the placing table 52 of the compressing device 50, it is possible to save space above the placing table 52 of the compressing device 50.

[0045] As described above, after the completion of the placing step S1 and before the start of the compressing step S4, since the top plate placing step S3 of placing the top plate 3 on the plurality of glass fiber packed bodies 2a placed on the placing table 52 of the compressing device 50 is further provided, the shape of the glass fiber package 2 can be stabilized.

[0046] In the lid body placing step S2, the top plate 3 is moved to a predetermined position above the plurality of glass fiber packed bodies 2a together with the lid body while being held by the suction pad 45 disposed on the lower surface of the lid member 42 of the lid body device 40, and then placed on the plurality of glass fiber packed bodies 2a. Therefore, the operation of placing the top plate 3 on the plurality of glass fiber packed bodies 2a placed on the placing table 52 of the compressing device 50 can be efficiently performed.

[0047] As described above, in the compressing step S4, since the placing table 52 of the compressing device 50 is raised to compress the plurality of glass fiber packed bodies 2a between the placing table 52 and the lid member 42 of the lid body device 40, it is not necessary to move the compressing device 50 when performing the compressing step S4. Therefore, the working efficiency when compressing the plurality of glass fiber packed bodies 2a can be improved.

[0048] As described above, in the compression step S4, by raising the mounting table 52 of the compression device 50 to a preset rising position, a plurality of glass fiber packed bodies 2a are compressed between the mounting table 52 and the lid member 42 of the lid device 40. Therefore, the obtained glass fiber package 2 can be accurately made to have a predetermined size. Also for this reason, in the compression step S4, it is possible to prevent an excessive pressure from being applied to the glass fiber packed body 2a and the glass fiber packed body 2a from being damaged.

[0049] As described above, after the completion of the compression step S4, since the apparatus further includes a tightening step S5 of integrally tightening a plurality of glass fiber packed bodies 2a with a tightening member, the compressed plurality of glass fiber packed bodies 2a are made into an integral body, and the handling of the glass fiber package 2 becomes easy.

[0050] As described above, in the glass fiber package manufacturing apparatus 1, the compression device 50 has a lifter 53 that enables the mounting table 52 to move up and down. By raising the mounting table 52 with the lifter 53, a plurality of glass fiber packed bodies 2a are compressed between the mounting table 52 and the lid member 42 of the lid device 40. Therefore, when performing the compression step S4, it is not necessary to move the compression device 50. Accordingly, the working efficiency when compressing a plurality of glass fiber packed bodies 2a can be improved.

[0051] As described above, the compression device 50 includes a first position detection device 54 that detects the vertical position of the mounting table 52. In the compression step S4, when the vertical position of the mounting table 52 detected by the first position detection device 54 reaches the preset rising position, the driving of the lifter 53 is stopped and the operation of moving the mounting table 52 upward is stopped. For this reason, the obtained glass fiber packed body 2a can be accurately made to have a predetermined size. Also for this reason, it is possible to prevent an excessive pressure from being applied to the glass fiber package 2 when compressing the glass fiber packed body 2a and the glass fiber packed body 2a from being damaged.

[0052] As described above, since the conveyance device 30 enables the lid device 40 (lid member 42 of the lid device 40) to move horizontally between the "arrangement position" located above the plurality of glass fiber packed bodies 2a and the "retreat position" spaced apart horizontally from the arrangement position, compared with the configuration in which both the "arrangement position" and the "retreat position" of the lid device 40 are provided above the mounting table 52 of the compression device 50, it is possible to save space above the mounting table 52 of the compression device 50.

[0053] As described above, the lid device 40, and the lid member 42 has a plurality of suction pads 45 on its lower surface and is configured to be able to hold the top plate 3 by the suction pads 45. Therefore, it is possible to easily realize a configuration that enables the lid device 40 to move from the "retreat position" to the "arrangement position" while holding the top plate 3.
