Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a conveying device for wound yarn packages.

[Conventional technology]

An example of an apparatus for conveying a full package wound up by an automatic winder, spinning machine, twisting machine, etc. to the next process is disclosed in Japanese Patent Publication No. 58-3948. That is, an L-shaped hook is hung on the overhead conveyor, and when the hook is moved,
There is a type in which an L-shaped hook enters the center hole of a package that has been doffed from a winding machine and is waiting, and the package is transported while being suspended from the L-shaped hook.

The device described above is suitable for transporting cone packages.

Further, for conveying cheese packages, there is an apparatus disclosed in Japanese Utility Model Application Publication No. 145844/1983. That is, in this case, both ends of the winding tube protruding from the yarn layer surfaces at both ends of the cheese package are supported and conveyed.

[Problem that the invention attempts to solve]

However, when transporting the above device by suspending it from an L-shaped hook for a cone package, there is no problem when transferring the package to the hook.
At the unloading position, the package can only be removed from the hook after it has been turned 180°, which requires a hook reversing device, resulting in a complicated structure, and the hook has a small center hole. Cheese packages cannot be transported.

In addition, the hanger for the cheese package, that is, the type that supports the winding tube at the center of the cheese package, is extremely difficult to transport the cone package.

The present invention solves the above-mentioned problems and provides a simple conveying device capable of conveying not only corn packages but also cheese packages.

[Means for solving problems]

In the present invention, a hanger suspended on a chain running along a track has a pair of fixed package support rods parallel to the moving direction of the hanger and spaced apart from each other at a constant distance, and the hanger Both sides in the package conveyance direction are openings through which the package can pass, and the distance between the pair of rods is larger than the dimension that allows the lift support for package transfer at the package transfer position to pass vertically, and the package The diameter of the package is smaller than the minimum diameter of the thread layer, and the package is transported with the outer peripheral surface of the thread layer of the package placed on the support rod.

〔Example〕

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

FIG. 4 shows an example of the layout of the package transport system. W1, W2, W3 are automatic winders, each automatic winder has multiple winding spans W
Each span consists of a plurality of winding units, which are the minimum units, arranged in parallel.

Full packages P1 to Pn doffed by each winder W1, W2, and W3 are conveyed to the end of the machine by conveyors C1 to C3 laid along the unit, and a package lifting device is installed at that position. The packages 1a, 1b, and 1c are lifted upward one by one and delivered to the package hanger 3 of the overhead conveyor 2 that circulates above.

Packages P are conveyed by the rotation of the conveyor 2 in the four directions of arrows, and the package conveyance tray T waits on the lower conveyor 6 at the position of the unloading device 5.
It is transferred and inserted on top. Thereafter, the package is conveyed together with the tray T in the direction of arrow 7 and supplied to a package inspection station 8. At the package inspection station 8, the packages that have been inspected for predetermined check items are sorted into acceptable packages and rejected packages.The rejected packages are sent, for example, to a branching path 9 by a movable guide 10, and are removed from the tray by a package extraction device 11. The extracted package Pi is stored in the box 12. On the other hand, the packages judged to be acceptable are discharged from the inspection station 8 and transported on the conveyor 13, and are transported to the package stock lines 14a to 14.
14c to the tray by extraction devices 15a to 15c.
Separated from Tr and stocked. The empty trays Tr and Ti from which the package cages have been removed are returned to the package receiving position R on the conveyors 16, 17, 18.
etc., and prepare for receiving the package.

An example of a package hanger 3 suspended from the overhead conveyor 2 is shown in FIGS. 1 and 2. The hanger 3 suspended by a support member 22 on a chain 21 running along a track 20 has an upper substrate 23, package support members 24a, 24b, 25a, 25b fixed to the lower surface of the substrate 23,
Package mounting rods 26, 27 connected between the lower ends of the support member, and the intermediate support rod 2
8, 29, and both sides in the package transport direction are provided with openings 30 from which the hanger and the package can be separated. The distance l between the package support rods 26 and 27 is set to a dimension that allows the elevating and lowering supports 31 and 31 for transferring the package and the hanger to pass through.
Regardless of the PS, the dimensions are such that the lower end position of the package yarn layer at the package delivery position is approximately constant. The length of the support rod shown in FIG. 2 is longer than the generatrix length of the outer periphery of the yarn layer of the package, and is dimensioned so that the entire length of the package in the axial direction can be placed thereon. With such a hanger 3, all packages can be transported regardless of the size of the package or the shape of corn, cheese, etc.

According to the hanger 3, the elevating body 31 in FIG.
is installed at each receiving and unloading location,
Packages can be delivered and delivered easily.

In FIG. 1, 32 is a device 32a, 32b for writing on the identification member 33 of the hanger 3 at the package delivery positions 1a, 1b, 1c in FIG.
32c is shown. Note that the reading device 34 provided at the unloading position 5 in FIG. 4 has almost the same configuration. That is, guide rollers 36 and 37 are rotatably supported by brackets 35 and 35 fixed to the guide rail 20, and contact the board upper surface 23a of the hanger to regulate the position of the board 23 in a horizontal state. Furthermore, a writing head 38 for the above information is provided at a position corresponding to the display member 33 for package manufacturer information fixed to the upper surface of the board of the hanger. The writing head 38 is fixed to a bracket 40 that can swing vertically about one axis 39 of the bracket 35, and the bracket 40 is slightly urged downward by a spring 41, and a guide roller 42 supported at the end of the bracket. As a result, the distance between the writing head 38 and the surface of the display member 33 is maintained constant, thereby ensuring a reliable writing operation. 43 uses a proximity sensor to confirm that the hanger 3 has arrived at the fixed position, and issues a writing timing signal.

For example, a rubber magnet that can be freely magnetized and demagnetized is applied to the display member 33. That is, the rubber magnet is divided into a plurality of sections, and by magnetizing or non-magnetizing N, S, etc. in each section, the manufacturer of the package can be indicated. For example, in the case of Fig. 4, if you want to show which span of which machine the produced package cage was produced, divide the rubber magnet 33 into six sections as shown in Fig. 3, and divide the first two sections into Machine No.Wi
, and the following four compartments are the span SPi. When transferring the package Pi doffed by the span SP3 of the winder W2 in Fig. 4 to the hanger,
It is magnetized by the head 38 like NSNNSN. Of course, it is also possible to write the winding unit number instead of the span SPi.

In contrast to the reading device 34 provided at the package unloading position, a reading device for reading information written on the tray can be provided at the package inspection station 8. In this case, if the distance between the unloading position 5 and the inspection station 8 is large and there are two or more packages between them, it is convenient to provide a reader, and the packages are immediately supplied from the unloading position to the inspection station. In such a case, the manufacturer information of the package under inspection can be obtained by the reading device 34 at the unloading position.

Further, when the packages that have passed through the inspection station 8 are distributed to the stock lines 14a to 14c of acceptable products, a reading device 62 is installed in front of the receiving position of the line closest to the inspection station in the stock line.

That is, when the information read by the reading device 62 is the third span SP3 of the winder W2, and the package is to be stored on the stock line 14b, the package P passes through the entrance of the line 14a and is placed on the stock line 14b. The package stops when it comes into contact with a stopper (not shown) waiting at the package extraction position 15b, and the package is extracted from the tray by the extraction device 15b and line 14b.
Moved above.

In addition, when there are many stock lines, if a reading device is arranged in the middle of the conveyance path 13, it becomes possible to convey a plurality of packages in the conveyance path 13 at the same time. The above stock lines 14a-1
4c is provided on one plane in the layout shown in FIG. 1, but it is also possible to install it in multiple stages in the vertical direction. By separating the conveyor and moving the conveyor vertically in parallel in an elevator manner, the package can be transferred to a predetermined stock line in a plurality of stages and rows of stock lines.

Next, the operation of the above system will be explained.
As an automatic winder applied to this system, for example, the winders shown in FIGS. 5 to 7 are convenient. That is, one automatic winder W1 has a plurality of winding units in one group, and this group is called a span, and the illustrated winder W1 is composed of four spans SP1 to SP4.
Each span is provided with storage devices 70a to 70d for temporarily storing fully wound packages. The stocking device has a stock bar that extends over one span, a position where the stock bar contacts the package, and a position where the stock bar comes into contact with the package, and a position where the stock bar is separated from the package and moves the stored packages all at once to the conveyor C.
1 and a stock bar operating source such as fluid cylinders 71a to 71d. The cylinders 71a to 71d are operated sequentially or randomly for each span. For example, in Fig. 8, if the average winding time T required to wind one full package is 60 minutes, and the stock bar opening operation time interval t is 50 minutes, then the deviation time dt, that is, when the stock bar is activated over a certain span, is 50 minutes. Assume that the time interval until the next span stock bar is activated is set to 10 minutes.

Now, in the span SP1 of FIG. 5, the stock bar 70a is actuated by the drive of the fluid cylinder 71a, and the plurality of stored packages PA are discharged all at once onto the conveyor C1 (FIG. 6). Due to the rotation of
The package is conveyed in the direction of arrow 72 and transferred to the lifter 1a position. The packages PA are transferred to the upper hanger 3 one after another by the lifter 1a, and each time a package PA is transferred, an identification symbol indicating the span SP1 is written on the display member 33 of the hanger by the writing device 32a. . That is, the fluid cylinder 71a of span SP1
As a result of this operation, the package currently being transferred on the conveyor is identified as being produced in span SP1, and the control device 73 on the winder side instructs the writing device 32a to write an identification symbol.

In order to avoid mix-up, it is necessary to set the time required for transferring one span of packages onto the hanger to the above time dt.

After the conveyance of the packages in the span SP1 is completed, the stock bar of the span SP2 is activated as shown in FIGS. 7 and 8, and the packages PA2 doffed in the span SP2 are delivered all at once onto the conveyor C1. Lifter 1 is transported in 72 directions.
The pieces are transferred to the overhead conveyor 2 one by one by b. At this time, the control device 73 informs the writing device 32b that it is the span SP2 package.
The display member 33 of the hanger shows the span.
An identification symbol indicating SP2 is written.

In this manner, the full packages discharged from the winders W1 to W3 are transferred to the hanger 3 of the overhead conveyor 2 one after another, and are conveyed together with the production winder and span identification symbol of the package.

When the package reaches the unloading position 5 shown in FIG. 3, it is transferred to a tray T on a conveyor belt 6 extending from the hanger to the inspection station 8. At this time, the identification symbol displayed on the hanger on which the unloaded package was placed is detected by the reader 34.
At the same time, the central controller 74 instructs the central controller 74 to write the identification symbol on a display member such as a rubber magnet on the tray T into which the package is inserted, and the writing device 75 transcribes the identification symbol.

Therefore, the manufacturer's span of the package on the tray T is displayed on the tray T, or by installing a tray identification symbol reading device in the package inspection device 8 or at an appropriate location on the conveyance and storage line. , the origin of the packages on the tray can be recognized.

The packages conveyed to the unloading position 5 by the overhead conveyor 2 are placed on the tray T as described above.
As the package is transferred to the top, the manufacturer information of the package is written on the tray, and the package transported together with the tray is checked for shape, weight, mixed numbers, etc. by a known inspection device at an inspection station 8. administered. By reading the manufacturer information of the tray on which the package that was determined to be rejected as a result of the inspection is placed at the station, the machine of the automatic winder that winds up the package is automatically installed.
No., Span No. or Winding Unit No.
etc. can be known.

By processing the inspection results at the inspection station mentioned above by the processing device 8a, it is possible to restore the inspection results of various packages, and it is possible to easily find out the package manufacturers that produce many defective packages. It can be done.

[Effect of idea]

As described above, in the present invention, the outer peripheral surface of the package thread layer is placed and supported by the package support rod of the hanger suspended from the overhead conveyor, so that it can be unloaded like a conventional L-shaped hook. There is no need to turn the package over during the package transfer, and the package can be transferred between the hanger and the lift support simply by lifting and lowering the lift support placed at the package transfer position. It is possible to transport regardless of the type and regardless of the diameter of the roll, which is particularly effective in high-mix, low-volume production systems. In other words, with the present invention, the package can be placed and transported using only two fixed rods, eliminating the need for a complicated support mechanism, and preventing the cylindrical package from rolling, ensuring reliable transportation and delivery of the wound yarn package. It can be done.
