Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tray that can hold package identification information and the like, and more particularly to a tray that can simplify a conveyor-side device for reading identification information.

[0002]

[Prior art]

 When transporting a yarn package on a conveyor in a factory, warehouse, etc., the package is placed on a tray to prevent the yarn from being damaged by contact with the conveyor. In addition, in order to sort the packages being transported by product type, product number, lot, manufacturing date, quality, weight, etc., it is also possible to provide the tray with the identification information of the packages currently being loaded. Generally, in order to give identification information to the tray, a storage medium carrying the identification information is provided in a part of the tray. The writing of the identification information on the storage medium is performed by the writing device in the process of placing the package on the tray. On the other hand, for reading, a reading device is appropriately arranged at a required position on the path of the conveyor.

Conventional trays include those with a round bottom (round type) and those with a square bottom (square type).

As shown in FIG. 4, the round tray 31 has a protrusion 32 formed in the center of one side of a disc 32 having a predetermined diameter, and the side having the protrusion 33 is used upward. The diameter of the protrusion 33 is large enough to fit the bobbin of the package, and the round tray 31 can be mounted with the end surface of the package horizontal. The round tray 31 transports a package by placing the tray 31 on which the package is placed on a conveyor and horizontally transferring it on a conveyor. Since the round tray 31 has no distinction according to the direction, even if the conveyor has a bent portion, it can be transferred without any trouble. On the other hand, since the round tray 31 is difficult to determine the direction, it is difficult to align the storage medium 34 and the reading device. Therefore, conventionally, when the tray 31 comes to the reading position on the conveyor, the tray 31 is rotated so that the storage medium 34 passes through the readable range of the reading device. When there are a plurality of storage media 34, these storage media 34 are arranged in the circumferential direction. By rotating the tray 31, the reading device can read the contents of all the storage media 34 while being fixed. For this purpose, a device for rotating the tray 31 is required.

As shown in FIG. 5, a rectangular tray 41 is a square bottom plate 42 having sides of a predetermined length and a holder 43 for holding a package attached thereto. The holding table 43 has an upright surface 44 that is vertically raised along one side of the bottom plate 42, and an inclined surface 46 that is inclined from the top 45 of the upright section 44 toward the opposite side of the bottom plate 42. In addition, a protrusion 47 is provided perpendicularly to the inclined surface 46 from the inclined surface 46. The bobbin 49 of the package 48 is fitted into the protrusion 47 to hold the package 48. The held package 48 will be tilted. The rectangular tray 41 has a bottom plate 42 placed on a conveyor and is transported horizontally on the conveyor. At this time, the upright surface 44 is placed so as to face the side of the traveling direction of the conveyor. Since the direction of the rectangular tray 41 is easily determined, the alignment of the storage medium 1 and the reading device 2 is easy. Conventionally, the storage medium 1 is attached to the rising surface 44. This advantage is in addition to the advantage of the above-mentioned alignment, and since the rising surface 44 is flat, the storage medium 1 having a plate shape, a chip shape, a tape shape or the like can be easily attached, and the rising surface 44 has a square shape. Therefore, the sticking position of the storage medium 1 can be easily determined, and since the storage medium 1 faces the side of the traveling direction of the conveyor, the reading device 2 can be arranged outside the conveyor.

A drawback of the conventional rectangular tray 41 occurs when the conveyor has a bent portion. For example, as shown in FIG. 6, it is assumed that two conveyors 51 and 52 are connected to each other so as to form a 90 ° bend. When the storage medium 1 on the upright surface 44 faces the side of the traveling direction of the conveyor 51 while the tray 41 flows on the upstream conveyor 51, when the storage medium 1 moves to the downstream conveyor 52, the tray 41a As shown, the storage medium 1 faces the traveling direction of the conveyor. Therefore, the reading device 2 cannot be placed at a position where it can be read. Therefore, conventionally, a turntable 53 for rotating the tray 41 by a predetermined angle is provided in the bent portion, and even if the turntable 53 moves from the upstream conveyor 51 to the downstream conveyor 52, the storage medium 1 moves in the traveling direction of the conveyor 52 as shown as the tray 41b. The tray 41 is turned so that it continues to face the side of the tray. However, for this purpose, the turntable 53 is required. The movement space of the turn table 53 needs to have a diameter larger than the diagonal line of the rectangular tray 41. Further, the turntable 53 is required for each bent portion.

As described above, the round tray and the square tray each have advantages and disadvantages. Another difference is that round trays can be stacked and square trays cannot be stacked when the trays are not used. The round tray requires less storage space when the package is stored. In addition, since the package of the square tray is tilted, the dripping does not expand to a certain extent even if the yarn end drips during transportation, but with the round tray, the outer periphery of the package stands, so the dripping of the yarn easily spreads. . In addition, the protrusions of the square tray are tilted, which makes it easier to attach and detach the package manually. On the other hand, the round tray has protrusions that make it easier for robots to attach and detach.

[0008]

[Problems to be solved by the device]

 The type of tray to be used for factories, warehouses, etc. is determined in consideration of the above advantages and disadvantages, but it is best if there is a tray that has both advantages. Conventionally, since there is no such tray, it is also possible to transfer the package from a round tray to a square tray depending on the application. A transfer machine is required for transfer.

By the way, the reason why the round trays can be stacked is not because the bottom plate is round, but because the package is placed on the bottom plate with the end face of the package horizontal. Even square trays should be able to be stacked by removing the holder and placing the packages on the bottom plate. The rectangular tray facilitates the positioning of the storage medium and the reading device because the direction can be easily determined. On the other hand, there is a problem of thread end sagging and a problem of requiring a turntable in the bent portion to change the direction of the storage medium. We have come up with a proposal for an announcement. Therefore, it suffices to solve the problem of the above turntable.

Therefore, an object of the present invention is to solve the above problems and to provide a tray that can simplify the device on the conveyor side for reading the identification information.

[0011]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention forms a square around the bottom of a tray in which a yarn package is carried and conveys the medium to be read that is read by the reading means at the corner of the bottom. It is stuck.

[0012]

[Action]

 With the above structure, a rectangular tray is formed on which the package is placed on the bottom plate. The medium to be read that is read by the reading means constitutes a storage medium that carries identification information and is attached to the bottom of this tray. Its position in the bottom is at the corner, that is, at any of the two sides intersecting each other. When this tray is conveyed on a conveyor, one side near the storage medium is located laterally in the traveling direction of the conveyor. Therefore, the storage medium reading device, which is the reading means, may be arranged on the side of the conveyor. Next, it is assumed that another conveyor is orthogonally connected downstream of this conveyor to form a bent portion. From this bent portion, the tray is transported in a direction perpendicular to the previous direction. Here, it is assumed that the other side close to the storage medium is located laterally in the traveling direction of the downstream conveyor. Even if the reading device is on the downstream conveyor, it may be arranged on the side. In this way, even if the direction in which the tray advances at the bent portion changes, the storage medium is located near both of the two sides that are orthogonal to each other, so that it can be read by the reading device arranged on the side of the conveyor. Therefore, it is not necessary to rotate the tray, and it is not necessary to provide a turntable at the bent portion.

[0013]

Embodiment An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

As shown in FIGS. 1 (a) and 1 (b), the tray 11 of the present invention has a square flat plate 12 and a rectangular protrusion 16 having a predetermined height at the center thereof. A columnar protrusion 13 is provided. The protrusion 13 is for fitting on the bobbin of the package, and the rectangular protrusion 16 is for mounting the package with the end surface of the package horizontal. The flat plate 12 constitutes a bottom plate 14 serving as a conveyance surface. The storage medium 1 carrying the identification information of the package is fitted in the corner portion 15 of the bottom plate 14. In this example, the storage medium 1 is provided at one of the four corners 15. FIG. 1 shows the surface having the protrusions 13, that is, the surface of the bottom plate 14, and the storage medium 1 is attached to the back surface of the bottom plate 14 so as not to project from the back surface.

In this embodiment, the storage medium 1 can store the package weight, type, manufacturing date, and the like. In this example, the storage medium 1 is called an ID tag or ID card, and is a plate-shaped substrate provided with a magnetic recording medium, and the stored contents can be carried as magnetic information. On the other hand, the reading device can read the stored contents within a predetermined distance from the storage medium 1 in a direction substantially facing the storage medium 1. The ID card of this embodiment can read data from a maximum distance of 30 cm. The storage medium 1 may carry optical information such as a bar code, or the storage medium 1 may be configured by an integrated circuit including a storage circuit.

FIG. 2 shows an example of the structure of a transfer line for transferring the tray 11 of the present invention. As shown in FIG. 2 (a), three linear conveyors 21 are connected to form a U-shaped transfer line 22. A right-angled bent portion 23 is formed at a connection point of each conveyor 21. As shown by the arrows, the feeding directions of the conveyors 21 are as follows: the conveyors on the upper side of the figure are from right to left, the conveyors 21 on the left side are from top to bottom, and the conveyors 21 on the lower side are from left to right. . The trays 11 to be transferred are shown on the respective conveyors 21. The width of each conveyor 21 is slightly larger than one side of the tray 11. Each conveyor 21 is composed of a large number of rollers 25 arranged between the outer frames 24 of the conveyor 21 and arranged in parallel in the longitudinal direction at predetermined intervals. Each roller 25 is rotationally driven by a drive mechanism (not shown). It By the rotation of the roller 25, the tray 11 placed on the roller 25 is transferred in the feeding direction indicated by the arrow.

In the bent portion 23, two endless belt devices 26 having a longitudinal direction parallel to the axial direction of the roller 25 and rotating in the longitudinal direction are provided between the rollers 25. The belt device 26 is provided on the upper surface of the roller 25 so as to be retractable and retractable. Below the roller 25, the tray 25 is allowed to be conveyed by the roller 25, and above the roller 25, The tray 11 is conveyed in the axial direction of the roller 25 by rotating the belt. The tray 11 is transferred between the conveyors 21, that is, the direction is changed by the belt device 26 appearing and retracting and rotating.

Although not shown, the transport line 22 is provided with various processing devices such as a sorting device that operates based on the stored contents, and the reading device 2 is installed side by side with these processing devices. In addition, a stopper that prevents the tray 11 from being conveyed is provided in the conveying line 22 so as to be retractable at an appropriate position.

The reading device 2 for the storage medium 1 is located between the rollers 25, and is provided so as to face the back surface of the bottom plate 14 of the tray 11 from below the conveyor 21, as shown in FIG. 2B. There is. In the reading device 2 of each conveyor 21, a support bracket 27 having a horizontal plane is attached to the outer frame 24 of each conveyor 21 in the vicinity of the inner side of the outer frame 24, and is attached to the horizontal plane of the support bracket 27. The distance between the reading device 2 and the conveying surface of the conveyor 21 is 30 cm or less at which the reading can be performed.

Next, the operation of the embodiment will be described.

In FIG. 2, the tray 11 is placed on the conveyor 21 on the upper side. The tray 11 has a corner 15 to which the storage medium 1 is attached, which is located at the upper left in the figure. Since the storage medium 1 is attached to the back surface of the bottom plate 14 of the tray 11, it faces downward. The tray 11 is moved in the feeding direction indicated by the arrow (from right to left in the figure), and when it reaches the reading position, it is stopped by the stopper. When the tray 11 is at the reading position, the storage medium 1 is located on the reading device 2 of the conveyor 21 on the upper side. At this time, since the reading device 2 faces the storage medium 1 and is within a readable distance, the storage content of the storage medium 1 can be read.

When the tray 11 reaches the first bent portion 23, the tray 21 is moved by the conveyor 21 on the left side in the feeding direction indicated by the arrow (from top to bottom in the figure). At this time, although the feeding direction changes at a right angle at the bent portion 23, the direction of the tray 11 does not change, so that the corner portion 15 to which the storage medium 1 is attached maintains the upper left position in the figure. The storage medium 1 passes over the reading device 2 of the conveyor 21 on the left side, and the reading device 2 can read the stored contents of the storage medium 1.

When the tray 11 comes to the next bent portion 23, the tray 21 is moved by the conveyor 21 on the lower side in the feeding direction indicated by the arrow (from left to right in the figure). Since the corner 15 to which the storage medium 1 is attached maintains the upper left position in the figure, it passes over the reading device 2 of the conveyor 21 on the lower side, and the reading device 2 can read the stored contents of the storage medium 1 here as well. Wear.

As described above, the orientation of the storage medium 1 is maintained even if the advancing direction of the tray 11 changes at the bent portion 23. This is the same regardless of the number of bent portions 23. Since the storage medium 1 is located near the corner 15 of the tray 11, that is, both of the two sides of the bottom plate 14 which are orthogonal to each other, the reading device 2 has a side edge of the conveyor 21 in any conveyor 21 having a vertical and horizontal feed direction. You can place it in. Therefore, the reading device 1 can be used by being fixed to the outer frame 24 or the like of the conveyor 21. Further, since it is not necessary to rotate the tray 11 at the bent portion 23, it is not necessary to provide a turntable on the bent portion 23.

Another embodiment of the present invention will be described.

The transfer line of FIG. 3A is similar to the transfer line of FIG. 2A, and three linear conveyors 21 are connected to each other to form a U-shaped transfer line 22. A bent portion 23 at a right angle is provided at a connection portion of 21, and the tray 11 is conveyed by the roller 25, and the belt device 26 changes the direction of the bent portion 23. The reading device 2 for the storage medium 1 is supported above the conveyor 21 by a support bracket 27, as shown in FIG. Since the horizontal portions of the reading device 2 and the support bracket 27 are located at the same height as the raised portion 16 of the tray 11, when the tray 11 on which the package is placed passes, it enters between the lower end surface of the package and the bottom plate 14. It is like this. In this case, since the reading device 2 does not interfere with the rollers 25, there is no restriction placed between the rollers 25, and the reading device 2 can be provided anywhere on the transport line 22. On the other hand, the storage medium 1 may be on the back surface of the bottom plate 14 or on the front surface thereof as described in the above embodiments.

Further, the medium to be read may be attached to the corner portion of the rectangular tray 41 of FIG.
