Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tray for conveying bobbins in automatic wine gourds, spinning machines, etc.

[Conventional technology]

A bobbin conveyance system that feeds each finished spinning bobbin individually into a tray and feeds it to the wine goo, or transports empty bobbins discharged from the wine goo to the spinning machine while placing them in a tray. There is.

In addition, as a system for conveying multiple types of bobbins using the above-mentioned independent trays, there are systems in which the bobbins themselves have identification marks, trays in different colors, or trays with grooves for identification. Using things, etc.
There is a system in which bobbins of different types are transported on a common conveyance path, and at a branching position, the type of tray or bobbin is determined using a mark sensor that reads the color, a gauge that detects the presence or absence of grooves, etc.

[Problem that the invention seeks to solve]

With the above trays, there is no problem if there are only two types, but if the number of types handled increases to three or four types, it becomes difficult to sort with the mark sensor, or when the number of grooves on the tray is increased. However, there are problems such as the need to change the size of the tray or modify the conveyance path itself.

SUMMARY OF THE INVENTION An object of the present invention is to provide a bobbin conveying tray that can reliably sort a wider variety of products using a tray that has the same shape as the existing tray.

[Means to solve the problem]

The tray according to the present invention is formed by mixing magnetic powder into a part or the whole of the tray.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, an example of a tray is shown. That is, the tray
(1) is a disc-shaped substrate (3) placed on a conveyor (2).
), a platform (4) formed on the top surface of the base (3) and having a smaller diameter than the base, and a peg (4) standing upright in the center of the base (4).
5) are integrally molded or fixed.

The tray (1) has an internal space (6) and an opening (7) at the bottom, and the top slope (8) of the peg has an air passage hole (9). The real bobbin (10) inserted above has a thread end (1) in the center hole (11).
2) is a type that can be integrally fed and rewound with the winding unit tray when it is inserted in a hanging manner. Note that it is of course possible to use a solid tray with the same external shape as the bobbin transport medium instead of the hollow tray described above, and in this case, it is not possible to supply the bobbin and tray as one unit to the winding unit. , requires a separate device for thread end entry.

Furthermore, the tray (1) shown in the first figure is molded from a synthetic resin material, and is molded with magnetic powder (Mg) such as iron powder or other metal powder mixed inside during the manufacturing process. In the case of FIG. 1, magnetic particles are uniformly distributed and mixed over almost the entire tray. A proximity sensor (13) activated by the magnetic particles (Mg) is installed on the transport path of the tray (1) just before the branch path, so that two types of trays, one containing magnetic particles and one without magnetic particles, can be distinguished. If a movable gate operated by the detection signal of the proximity sensor (13) is provided in the branch path, it becomes possible to selectively transfer two types of trays.

Note that the tray (14) shown in the second figure also contains magnetic powder (M
g) is mixed into one piece, but magnetic powder is mixed only in the vicinity of the outer peripheral surface of the base (15), and can be identified in the same way as the tray in Figure 1.
1) It is also possible to change the location where magnetic particles are mixed depending on the transportation form in (14) or the installation position of the proximity sensor.

In addition, as a conveyance means for trays (1) and (14), as shown in Fig. 1, the trays are placed on a flat belt conveyor (2).
(1) is placed and transferred, and the guide plate (16) (16)
A type in which the tray base (4) is regulated by a gap between the trays and a conveyance path is set, or a type in which the tray (14) is conveyed by a round belt conveyor (17) as shown in Fig. 2. Various means of transport are possible.

FIGS. 3A to 3D show an example of a tray configuration in which four types of bobbins are conveyed using the tray having the magnetic powder described above. That is, the tray (TA) in FIG. 3A is a tray that does not have magnetic particles and does not have an identification groove in the base (3), and the tray (TB) in FIG. 3B is a tray that contains magnetic particles (9 g). This tray does not have an identification groove. 3rd C
The figure shows a tray that does not contain magnetic particles and has an identification groove (18), and the tray (TO) in Figure 3D has magnetic particles (Mg).
It is also a tray in which an identification groove (1B) is formed.

A bobbin dedicated to each tray is inserted into each of the trays (T^) to (TD), and the type of bobbin is determined by identifying the type of the tray.

FIG. 4 shows an example of a bobbin conveyance system using the various trays (TA) to (TD) described above.

In Figure 4, (SA) to (SD) are spinning machines, and each machine produces a different type of yarn, and the spinning machine (SA) produces yarn of type A, and each machine (SR )
At (SC) and (SD), yarns of type B, type C, and type D are produced, respectively.

On the other hand, in winding (Wl) (W2), the machine base consisting of a large number of winding units is essentially divided into two groups, and each divided section (WIC) and (W2B ) (W2O)
At this point, threads of different varieties are rewound. The above-mentioned wine goo is, for example, one in which winding units disclosed in Japanese Unexamined Patent Publication No. 58-59167 are arranged side by side. That is, the spinning bobbins produced by each spinning machine are conveyed and supplied to the winding unit while being inserted in the tray, and are rewound, and the empty bobbins are also discharged from the winding unit while being inserted in the tray.

Each of the above spinning machines (SA) to (SD) and wine spinning machines (Wl) (
W2) A conveyance path (L) for a tray in which spinning bobbins or empty bobbins are inserted is formed by a belt conveyor.

The above-mentioned conveyance path (L) includes a main conveyance path (Ll) common to trays for various bobbins, and a conveyance path 11 on each spinning machine and wine goo side that joins or branches to the main conveyance path (Ll)
2) It is formed from ・-, etc.

That is, for example, in a spinning machine (SA), the empty bobbin input path (11) and the spinning bobbin delivery path (fl) are connected to the main transport (Ll).
), and the spinning bobbins produced by the spinning machine (SA) are delivered together with the tray onto the branching path (R2), and are sent in the direction of the arrow (19). and is transported toward Waing along the main transport path (Ll).

On the wine goo side, the loading path (R5) (β6) for spinning bobbins from the main conveyance path (Ll) is connected to the wine goo (Wl).
(W2), and yarn end preparation devices (20) and (21) are arranged in the middle of the carry-in path, and the spinning bobbin with the yarn end taken out is sent to the winding unit in the state shown in Fig. 1. transported. On the other hand, the empty bobbin discharged from the winding unit or the bobbin with remaining thread remains integrated with the tray and moves along the return path (22) (23) along the arrow (24).
) direction, and is transferred to the remaining yarn processing station (25) (
26), the remaining yarn of the bobbin having extremely little residual yarn is removed, and the bobbin becomes an empty bobbin, which is transferred to the main conveyance path (Ll
), and the half-ball bobbin having a large amount of remaining thread passes through the bypass' (27) (28) and is again supplied to the preparation device (20) (21).

Therefore, in the case of this embodiment, there are 4
Trays with different types of spinning bobbins are transported, and
Trays containing four types of empty bobbins are transported, and a tray identification device is provided at a branch position of each transport path.

For example, each tray (
Bobbins of types (A) to (D) are inserted and conveyed at TA) to (TD) to be used as ornaments.

That is, an identification gauge is arranged on the branch path (R1) of the main conveyance path (Ll) to identify the presence or absence of the groove (18) in the tray.
For example, only the trays (TA) (TB) without grooves can be connected to the branch path (
R2) Tray with grooves (TC) (TD)
is the main conveyance path (Ll) in the direction of the spinning machine (SC) (SD)
Transfer the top.

The tray (TA) taken into the branching path (R2) is connected to the empty bobbin loading path (β1) dedicated to the spinning machine (SA) and the branching path (R2).
2) is carried to a predetermined spinning machine (SA) by a proximity sensor (Fig. 1 (13)) that detects the presence or absence of magnetic particles provided at the joining position (rl) and a movable gate operated by the detection signal of the sensor. Ru. Therefore, the branch position (rl)
All trays with empty bobbins that are not taken into the spinning machine (SA) are B-type trays (TB), so there is no need to provide a sensor at the branching position (β2). All empty bobbins that have been used can be transported to the spinning frame (SB).

Furthermore, other products (C) are transported on the main transport path (Ll).
(D) Tray with empty bobbin (TC) (TD)
is only a grooved tray, and at the branching position (β3), only the tray (TC) is taken into the spinning frame (SC) by the proximity sensor and the movable gate, similar to the branching position (rl), and the branching position The tray that reaches (β4) is therefore the remaining D
Since only the type tray (TD) is provided, there is no need to install an identification bag device at position (β4) and the empty bobbin tray (TD)
can be taken in.

In addition, a branch position device (
In R2), a tray (T
A) to (TD) are coming, but if the tray (TA) (TC) without magnetic particles is to be taken in at Wine Goo (Wl), a proximity sensor and a movable gate will be installed at the branch position (R2). If this is done, only the trays (TA) (TC) can be taken in on the carry-in path (C5), and the remaining trays (TB) (TD) will arrive at the branch path (R3) and the identification device will be loaded. You can just take it in without having to set it up.

The trays (TA) and (TC) carried into the loading path (15) of the Wine Goo (old) are the tray with identification groove (TC) and the tray without emotion (TA), so it is time to branch to the winding section (WIC)! If (C5) is provided with a gauge that engages with the groove, the grooved tray (
TC) is the only supply path (29) in the section (WIG)
The remaining tray (TA) is automatically loaded into the feed path (30) in the next section (WIA).

Similarly, in Wine Goo (Δ2), a grooved tray (TD) and a pitless tray (TB) are installed in the entry path (C6), and only a gauge is installed at the branch position (C6) of the section (W2B). Then, the tray (TD) is connected to the section (W
2B), and the remaining tray (TB) is automatically loaded into the section (W2B).

In addition, the above branch positions (R1), (C5) (C6)
An example of the identification gauge provided on the vehicle will be explained with reference to FIG. 5.6. That is, for example, at the branch point (C5), as shown in FIG. 5, following the guide plate (31), a tray sorting member (33) and a sorting guide member (34) for sorting the trays in two directions are provided. The above sorting member (33)
As shown in Fig. 6, the pin (36) is loosely fitted onto the fixed bracket (35) and can freely swing vertically within the range of angle (θ) around the pin (36). It consists of a standard play) (37) and a selection gauge (38) fixed to the plate (37) in parallel with the play (37) at a distance (hl) below the plate (37). ing.

The side edge of the reference plate (37) has a parallel part (39) parallel to the conveyor rotating direction, and following the parallel part (39),
The plate (37) has an inclined part (40) inclined toward the passageway (32), and both ends of the plate (37) have an enlarged part (40) facing upward.

The lower surface (37a) of the plate between (41) is used as a reference surface, and is the surface that comes into contact with the upper surface (3a) of the base (3) of the tray (1).

As shown in Fig. 6, the sorting gauge (38) has a mounting part (42) attached to the reference plate (37), a vertical part (43) bent perpendicularly from the mounting part (42), and a further vertical part. (43) and a gauge part (44) bent at right angles are integrally machined from sheet metal, and the gauge part (44) is the width (S) of the groove (18) of the tray (1).
A thin plate with a thickness 1) that is sufficiently smaller than the gauge (38
) is the reference surface (37a) of the reference plate (37).
It is fixed by screws or welding so that it is parallel to the entire area. Furthermore, the guide edge of the gauge (38) has an inclined portion (4) inclined toward the center of the conveyor (2).
5) (46) and a parallel portion (47) formed at the top between the inclined portions (45) and (46).

On the other hand, the guide plate (
31a) includes an inclined part (48) or a curved part, a parallel part (31al), etc., through which the trays that do not enter the intake port are sorted by the guide member (34) and transferred through the conveyance path (11). It becomes more.

Furthermore, the sorting guide member (34) fixed to the frame has an acute-angled tip (4) located approximately at the center of the conveyor belt (2).
9), which is connected to the tip (one guide edge (50) forms a tray entry passage with the inclined surface (40) of the guide member (37), and the other guide edge (51) is opposite A conveyance line (15) is formed by the parallel part (31al) of the guide plate (31a).The position of the tip (49) of the sorting guide member (34) is ) into the groove (18) of the tray that enters the gauge (3).
8), the center (R2) of the tray (1), which has passed through the tray, is deviated by a distance (m2) toward the intake port (32) from the contact point (χ2) between the tip (49) and the tray base. , and when the tray (1a), which has no groove at the position corresponding to the gauge (38), is pushed and transferred by the gauge (38) toward the guide plate (31a) and comes into contact with the tip (49), The center (Pl) of the tray (1a) is set at a position that deviates from the contact point (Xl) by a distance (ml) toward the transport line (R5).

Further, FIG. 7 shows an example of a device for identifying trays containing magnetic particles from other trays using a proximity sensor and a movable gate. For example, in a spinning frame (SA), the branch position (r
In l), the proximity sensor (13) and the movable gate (G)
is provided.

When the sensor (13) is off, that is, when no magnetic particles are detected, the gate (G) is at the position shown by the chain double-dashed line (so that only trays (TA) without magnetic particles are carried into the spinning machine (SA). G
1) and passed through the sensor (13).
In A), the guide plate (52) restricts the advancing direction of the table base (4) of the tray, and the tray is taken into the empty bobbin loading path (pl).

On the other hand, when the tray (TB) containing magnetic particles reaches the sensor (13) position, the sensor is turned on and the gate drive solenoid (53) is activated, the gate (G) moves to the solid line position, and the carry-in path (β1 ) and close the entrance of the tray (TB).
is conveyed along the branch path (rl) in the direction of the arrow (54).

In addition, in the system of this embodiment, in the spinning machine area, trays with empty bobbins and trays with spinning bobbins are conveyed in a mixed manner on the branch path (L2) and the main conveyance path (Ll). Furthermore, as shown in Fig. 7, the spinning bobbin (
A) is inserted into the tray (TA) through the empty bobbin loading path (11).
) It is desirable that the guide member (55) is fixedly installed on one side of the conveyance path so as not to be taken into the conveyance path. That is, the guide member (55) shown in FIG. (55) acts to push the surface of the yarn layer, and as a result, the tray (T
A) is pushed to the other guide edge (57) side of the conveyance path (L2), and at the branch position (rl), the conveyance path (11)
It is designed to be transported in the direction of arrow (54) without being transported to the side.

The guide member (55) is connected to each other spinning machine (SB) (SC).
) (SD) as well.

In addition, in the wine goo area, empty bobbins and spinning bobbins are mixed on the main conveyance path (Ll) as described above, and in this case, it is necessary to take in only the spinning bobbins, for example, at the branch position (R2). is the section (WIA) (
It is necessary to take in only spinning bobbins for WIC), and therefore the branch path shown in Figure 8 is constructed.

That is, immediately before the branch position (R2) of the wine goo (111), there is a tray (T) in which the spinning bobbins (A) and (C) are inserted.
A) A guide plate (58) that shifts only (TC) to the - side of the transport path (Ll) is fixedly installed at a position opposite to the branch path (15), and a proximity sensor (13) is installed. Placed. A movable gate (60) that is moved to two positions by a rotary solenoid (59) activated by a detection signal from the sensor (13) is provided at the branch position. Therefore, the tray (T) with the empty bobbin is not acted upon by the guide member (5 days) and is transported in the direction of the arrow (61) along the movement locus shown by the dashed line (port 1). Attach the tray (T) to the triangular guide plate (62) at the branch position
) is restricted and the tray on the main conveyance path (Ll) side is slightly deviated, so empty bobbins are not taken into the branch path (R5).

In addition, among the trays having spinning bobbins deviated toward the branching path side by the guide member (58), wine goo (1+1
1) only trays (T8) (TC) need to be carried in, so the sensor (13) remains off for trays (TA) (TC) that do not have magnetic particles; The movable gate (60) is held at the dashed line position and the tray (T
A) (TC) is transported along the trajectory (02) and is moved by the guide plate (62) to the tray (T) with spinning bobbins.
A) (TC) is the only access road (1) to Waingoo (Wl).
5).

On the other hand, when the tray (TB) (TD) containing the spinning bobbin reaches the sensor (13) position, the tray (TB)
(TD) has magnetic particles, so the sensor (13) is turned on, so the solenoid (59) is activated to move the movable game)
(60) moves to the two-dot chain line position (60a), closes the entrance of the branching path (15), and the tray (TB) that reaches the entrance
(TD) is pushed to the main conveyance path (Ll) and the tray (TB) (TD) is conveyed toward the wine goo (Kyo 2) downstream.

In addition, although the guide member (58) shown in FIG. 8 is provided also at the branch position (R3) in the wine goo (W2), it is not necessary to provide the sensor (13). That is, the spinning bobbins that reach the branching position (R3) are only of B and C varieties,
Even if the sensor (13) shown in FIG. 8 is not provided, it is automatically taken into the carry-in path (7!6). Of course, the branch position (
Tray with spinning bobbin (TA) that accidentally passed through R2>
In order to prevent the (TC) from being taken into the wine goo (2), it is also possible to provide a tray magnetic particle detection sensor at the branch position (R3).

In the manner described above, the four types of bobbin trays transported on the common transport path (Ll) can be taken into a desired dedicated transport path.

Although four types of trays have been described in the above embodiment, the number of types is of course not limited to four, and any number can be applied. For example, two types of trays that can be reliably detected by the mark sensor If the tray is applied, the presence or absence of the above magnetic particles,
It is possible to identify six types of trays by combining the presence or absence of identification grooves, the difference in color (for example, white and black), etc.

〔Effect of the invention〕

As described above, in the present invention, by mixing magnetic powder into the tray on which bobbins are inserted and transported, the type of tray can be easily and reliably identified using a proximity sensor, further automating the transport of a wide variety of bobbins. In addition, it is possible to reliably identify the product type.
