Abstract

PURPOSE:To shorten storing time and to dispense with a large space for storing by stocking packages in a stock station while storing them in boxes by means of a package transfer device and self-running carriage. CONSTITUTION:When packages P1, P2 subjected to a doffing process by means of a winder are transferred and placed on a conveyor belt 3, and when they are aligned at specified positions, they are simultaneously dropped down to respective portions 42a-42d of a receiving vessel 4. Four packages are simultaneously dropped while being rotated into specified sectional passages 43a-43d of a package storing box 1 when the packages are placed onto the vessel 4. Hence, when the box 1 is charged with a specified amount of packages, the fully charged box 1 is suspended by means of a carriage running on ceiling and transferred to a stock station, then it is stocked therein. It is thus possible to shorten storing time by the execution of transferring by groups and to dispense with a large space for stocking.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a package conveying device.

[Conventional technology]

A wound yarn package produced by a winding machine such as an automatic winder is self-transported to a desired position for the next process by various conveying means.

For example, Utility Model Publication No. 55-34187, Special Publication No. 55-34187,
There is one disclosed in Japanese Patent No. 2385. That is, at the end of the winder machine, the packages are lifted up one by one by means of a handshake and hung one by one on a ceiling hanger to separate and transport the packages.

[Problem that the invention seeks to solve]

In the above device, packages are transported one by one while being hung on hangers, so if the packages are to be stocked, it would require an extremely long transport path and a large number of hangers. , the storage space becomes extremely large. Furthermore, when unloading packages from hangers and stocking them, an unloading device and a conveying device are required, which increases the number of times packages are transferred and loaded, and there is a risk of damaging the thread layer.

The present invention aims to solve the above problems.

[Means for solving problems]

The present invention uses a device that transfers puff cages produced in a winder to a package storage box, and a self-propelled cart that supports the box and transports the box to a predetermined station. It is designed to be stocked at the station.

〔Example〕

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

Figures 1 and 2 show a transfer device (2) that neatly transfers packages doffed by a winder into a storage box (1).
This is an example.

The transfer device (2) includes a conveyor belt (3) for pitch-feeding packages, a package box (1) positioned with a slight inclination to the side of the conveyor (3), and a plurality of boxes on the conveyor. It consists of a rotating receiving tray (4) that transfers packages all at once into a receiving box.

The package box (1) has a bottom wall (I) as shown in the third figure.
d), side wall (1e) (If), end wall (1g) (1a
), and inside the box there is a partition plate (5a) (5
b) (5c), or a simple rod fixed to the bottom of the partition member, etc. is fixed, and the package entry side wall (1a
) is formed with a notch (1b), and the rotating saucer (4)
can be pivoted into the box via the notch (1b).

The box (1) is further formed with flange portions (7a) and (7b) that are engaged with support arms of an overhead traveling truck, which will be described later. Further, as shown in FIG. 2, the box (1) is placed on support rods (8) and (9) of different heights, and is positioned with the bottom surface of the box inclined. (10) (10) is a box stopper, (11) and (12) are left and right positioning pieces. For example, the upper part of the stopper (10) (10) and the positioning piece (11) (12) is (10a).
It expands outward as shown in the figure, and acts as a centering mechanism when the box is suspended from an overhead carriage and lowered.

On the other hand, as shown in the first diagram, the package pitch conveyor (3) is formed by a flat belt conveyor placed between a driving roller (13) and a driven roller (14).
5) rotates in the direction of arrow (16).

In addition, as shown in Fig. 2, a guide lff1 (17) (
18) are provided along the rotating direction of the conveyor, the guide plates (17) and (18) are lowered inward to form a trough-shaped surface, and when a package is placed, the conveyor belt moves along the trough-shaped surface. The position of the package is stabilized during transport. One of the guide plates (17) and (18) above, that is, the guide plate (18) on the box (1) side
is able to pivot around one axis (20) by the action of the cylinder (19), and when it pivots to the two-dot chain line position (18a), the package on the belt falls onto the tray (4) due to its own weight. There is.

As shown in Figure 1.2, the saucer (4) installed between the conveyor belt (3) and the box (1) is curved into an axis (21) extending parallel to the rotating direction of the belt (3). A saucer (22) forming a package receiving surface is fixed, and the saucer (22)
) Partition plates (23&) to (23C) are fixed to the inner surface at a pitch equal to the partition pitch (a) of the box.

In addition, if the partition plates (5a) to (5C) of the box (1) extend to the end face of the box, be sure to close the tray so that it does not interfere when the tray rotates to the position (4a) indicated by the two-dot chain line in Figure 2. A slit for passage of the partition plate of the box is formed at the pitch (a). In any case, the saucer (4
) rotates between the side of the conveyor (3) and the vicinity of the bottom of the box (1) to reduce the impact when the package falls and prevent damage to the thread layer. (24) is a fluid cylinder for rotating the saucer (4), and a piston rod (26) is connected to a lever (25) fixed to the shaft (21) to rotate the shaft (21).

FIG. 4 shows a self-propelled cart (30) that hangs and supports the package box and travels on the ceiling. The traveling trolley (3
0) is a main body (32) that runs along a single rail (31) like a mole rail, an elevating body (33) that can be lowered and raised from the main body, and a device provided on the elevating body (33). It consists of a box support arm (34). The above-mentioned elevating body is suspended by four bells) (35).
5) It is raised and lowered by the winding and unwinding, and the raising and lowering stroke can also be controlled by controlling the winding amount and unwinding amount of the belt (35), or by a lifting body detection sensor installed in the height direction at a predetermined station. Any stroke is possible. Therefore, the cart (30) has the three functions of box transport, palletizing, and day palletizing, and can transport the box (1) from the package storage station to the storage station.

Arm for supporting the box (34a) ~ (34
Various methods are possible for d), but in this embodiment, as shown in Figure 3.4, the lower end of the L-shaped arm is engaged with the collars (7a) and (7b) on both sides of the box (1). The type in which the portion (36) engages is shown.

Next, the operation of each of the above devices will be explained.

In Figure 1, a package doffed by a winder is transferred in the direction of arrow (37) and placed on conveyor belt (3).
When the sensor (37) detects the package, the motor (15) is driven and the package on the belt moves in the direction of the arrow (16). Note that various methods can be used to pitch the package. In this embodiment, pitch feeding is performed by controlling the drive time of the motor with a timer. That is, the motor is driven for a certain period of time after the sensor (37) detects the package. The drive time of the motor and the rotation speed of the output shaft (38) are in a corresponding relationship, and therefore the gear (39) of the output shaft (38) and the drive shaft (40) on the conveyor side form a transmission system using the gear (41). This makes the amount of feed of the belt (3), that is, the amount of rotation, constant.

When the package (P) moves a fixed pitch (a) and reaches the position (Pl) shown in the first diagram, the belt once stops. Subsequently, when the next package (P2) is placed on the belt, the belt (3) rotates by the fixed pitch (a) again in the same manner as described above. In this way, when the packages (four in this example) are lined up at predetermined positions on the belt (3),
The rotating fluid cylinder (19) of the movable guide plate (18) at the lower part of the belt operates, and as shown in FIG.
8) pivots to the two-dot chain line position (18a). Therefore, the four packages on the belt are placed in the saucer (4
) to each section (42a) to (42d). When it is confirmed directly or indirectly that the package is placed on the saucer (4), the fluid cylinder (2) shown in FIG.
4) is activated, and the saucer (4) is moved to the position indicated by the two-dot chain line in Figure 2 (4).
a), and the four packages in the tray move all at once to the predetermined section passages (43a) to (43d) of the box (1).
Transferred to Japan.

In this way, the packages are stored one after another in the box (1), and when a predetermined amount of puff cages are stored, the fourth
As shown in the figure, the full box (IA) of the package storage station (STI) is suspended by an overhead carriage (30), transferred to the stock station (ST2), and stocked. i.e. station (STI)
Belt (35) from the trolley body (32) stopped above the
As the box (1) is released, the elevating body (33) descends, and after the engaging portion (36) of the arm operates to support the box (1), the elevating body (33) ascends along the arrow (44). , as the cart moves in the direction of the arrow (45), the package box (IB) moves to a predetermined station (ST2),
The unloading IC) is carried out.

As described above, a plurality of packages doffed by the winder are neatly stored in boxes, and the boxes are transported and stocked together with the storage station.

In addition, in the above embodiment, the conveyor (3) is
A receiving tray (4) is placed between the package and the box (1), and the package on the conveyor is once placed on the receiving tray, and then the receiving tray is rotated to accommodate the package in the box. In this case, it is suitable for packages whose yarn surface is easily damaged, or for packages that require severe quality depending on the application. In addition, in the case of yarn that can withstand some impact, the saucer (4) can be omitted and the box (1) can be used.
The receiving side end face (1a) of the conveyor (3) is
It is also possible to position the tray (4) at the solid line position in the figure and drop it directly from the conveyor into the box.

Furthermore, in the above embodiment, a case was described in which four packages are lined up at a fixed pitch on the conveyor belt (3) and then stored all at once in a box, but of course the number of packages depends on the size of the box and the number of packages. It is optional depending on the size.

Furthermore, it is also possible to accommodate one package in the box (1) every time one package is transferred onto the conveyor belt (3). In other words, when accommodating one defective package at a time in this way, the defective packages are not dropped from the conveyor belt (3) into the box, but are stored on the belt (3).
3) It is possible to pass the package directly over the top and separate it from normal packages.

〔Effect of the invention〕

As described above, according to the present invention, packages produced in a winder can be transferred and transported to boxes in groups, reducing storage time and not requiring a large space for stocking packages. .
