Is to have.

[0003]

[Problems to be solved by the device]

In the above tray transfer device, since the length of the standby path L ₃ is short, a large number of full package insertion trays cannot be kept on standby, which is a cause of obstacles to automatic operation. By the way, the package P output by the output device 3 is on standby at that position, and when the package P is cut out to the carry-in path L ₁ , the empty tray T is discharged from the unit 2 to the carry-out path L ₂ . Made by the signal of time. Further, the tray T that has entered the carry-in path L ₁ automatically enters the standby position of each unit 2. However, an error in the tray ejection signal or an error in taking in the tray T from the carry-in path L ₁ to the unit 2 may occur. In that case, the tray T that has not been taken into any of the units 2 becomes stagnant at the terminal end of the carry-in path L ₁ and must be removed by the worker. It is one of the causes.

The present invention makes it possible to prepare a large number of package insertion trays, and returns trays that have not been taken into any unit from the carry-in path to the carry-in path again to enable automatic operation. The purpose is to provide a device.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the tray transport device of the present invention has a carry-in path for supplying an actual tray to each unit of the yarn spinning machine, a carry-out path for discharging an empty tray from each unit, and its downstream end and a carry-in path. A standby path that connects the upstream ends of the paths and temporarily waits to determine the presence or absence of yarn on the bobbin; an empty tray standby path that accepts empty trays from the standby path and temporarily waits to change the yarn supply tube; and its downstream end. It consists of an actual tray standby path that connects the upstream end of the carry-out path, and a stopper that is provided at the downstream end and that is opened when there is no tray in the output device.

[0006]

[Work]

 In the tray transporting device configured as described above, when the yarn supply package is emptied during the yarn mixing process in each unit, the tray is discharged to the carry-out path, and the unit is ready for tray loading. On the other hand, the package that has been ejected is taken into the unit that is ready to take in the tray from the carry-in path. Even if a tray take-in error occurs, the tray is sent from the downstream end of the carry-in path to the actual tray standby path and moves to the carry-out path, the standby path, and the carry-in path. Further, the tray determined to be an empty tray in the standby path is sent to the empty tray standby path, the yarn feeding is exchanged by the worker, and the actual tray standby path is sent. Then, from there, it is sent to the carry-out route.

【Example】

 With reference to FIG. 1, a tray transfer device of the present invention will be described.

This tray transport device includes a carry-in path L ₁ for supplying a tray T (hereinafter referred to as an actual tray) in which a package P is inserted into each unit 2 of the yarn winding machine 1, and a yarnless bobbin from each unit 2. A bobbin thread inserted into the tray T, which is connected between the carry-out path L ₂ for discharging the loading tray T (hereinafter referred to as an empty tray) and the downstream end of the carry-out path L _{2 and} the upstream end of the carry-in path L _1. A waiting path L ₃ for temporarily waiting to determine the presence or absence, and an exit device 3 disposed near the downstream end of the standby path L ₃ for processing the yarn end of the package P and issuing by the exit device 3. a bypass passage L ₄ for returning the tray T of the package P that could not be in the waiting path L _3, accept the tray T that is determined to empty tray in the waiting path L _3, is temporarily waits for performing Kyuitokan換Empty tray standby path L ₅ and empty tray standby path The actual tray standby path L ₆ that connects the downstream end of L _{5 and} the upstream end of the carry-out path L ₂ is provided at the downstream end of the actual tray standby path L ₆ , and the actual tray T exists at the position of the output device 3. It is composed of a stopper 8 that can be lowered when not in use.

Each unit 2 of the yarn winding machine 1 forms one yarn winding package from two yarn supplying packages P, and the yarn winding machine 1 is configured by arranging a plurality of the units 2 side by side. ing. When the yarn breakage of the yarn supplying package P occurs during the compounding, the yarn breakage signal is issued from the unit 2. Each unit 2 can accommodate three trays T of two pairs, for a total of six trays. Reference numeral 7 is a control box for performing various controls.

The carry-in path L ₁ and the carry-out path L ₂ are extended along the back surface side and the front surface side of each unit 2, and each of them is composed of a round belt passed between pulleys (not shown). These driving directions are opposite to each other, as indicated by arrows. Further, the drive introduction passage L _1, may be performed by sensing the sensor is not shown that the tray T is cut out introduction passage L ₁ from the lead unit 3.

The actual tray T that has not been taken into any of the units 2 is transferred to the actual tray standby path L ₆ from the downstream end of the carry-in path L ₁ and stopped by the stopper 8.

The standby path L ₃ is also made up of a round belt passed between pulleys (not shown), is formed so as to surround the blower box 4 at the end of the yarn winding machine 1, and is provided at the downstream end of the carry-out path L ₂ . To the upstream end of the carry-in path L _{1 in} a U-shape. A device 9 made of a phototransistor or the like for determining the presence or absence of the thread of the bobbin inserted in the tray T is installed in the middle of the standby path L ₃ , and a branch to the empty tray standby path L _{5 in} front of it is provided. A switching lever 10 is provided in the section. The tray T sent to the standby path L ₃ is once stopped at the position of the yarn presence / absence determining device 9, and the presence or absence of yarn is inspected. When the yarn presence / absence determining device 9 determines that there is a yarn, the switching lever 10 shuts off the empty tray standby path L ₅ , and the tray T is distributed to the outlet device 3 side, where the yarn end is ejected. .. When the yarn presence / absence discriminating device 9 determines that there is no yarn, the switching lever 10 does not act and goes straight.

[0013] mouth detection device 3, provided near the downstream end of the waiting path L _3, the bobbin the remainder put several winding the yarn end of the package P fed one by one from the standby path L ₃ on the bobbin head A so-called lead-out process is performed to insert it into the center hole of the. The tray T of the package P that has been ejected is on standby at that position, and is supplied to the carry-in path L ₁ when a tray discharge signal for discharging the tray T to the carry-out path L ₂ is issued from the unit 2. To be done. The structure of the yarn feeding device 3 is the same as that conventionally used for the yarn feeding package of the cone-to-corn type automatic winder. Hand over to.

The bypass path L ₄ is a gravity conveyor having a plurality of rollers arranged in parallel and sliding down by the gravity of the tray T. The carry-in path L ₁ is at a higher position than the carry-out path L ₂ , and the tray standby path in each unit ₂ is inclined from the carry-in path L ₁ to the carry-out path L ₂ , but the bypass path L ₄ is also provided in each unit 2. It is inclined at the same slope as the tray standby path.

A switching lever 5 that is rotated by an air cylinder 6 around a support shaft is provided at a branch position of the bypass path L _{4 and} the carry-in path L ₁ . When the yarn end of the package P cannot be discharged by the discharging device 3, the switching lever 5 rotates 45 ° from the position shown in the figure to shut off the carry-in path L ₁ . Thus, the tray T is directed to the bypass passage L ₄ side.

The bypass path L ₄ is provided with an alarm (not shown) for notifying that the tray T has accumulated, and the package P directed to this tray is treated by a worker so that it can be taken out. Then, they are returned to the standby path L ₃ one by one.

The main part of the empty tray standby path L ₅ extending along the rear of the yarn spinning machine 1 is composed of a front-loading conveyor that intermittently feeds the empty tray T forward and forward. A pusher 11 operated by an air cylinder for drawing in the tray T turned from the standby path L ₃ is provided at the entrance of the empty tray standby path L ₅ . At the downstream end side of the empty tray standby path L ₅ , an operator pulls out empty bobbins from the accumulated tray T and inserts a full package P therein. At the downstream end of the empty tray standby path L ₅ , when a device 12 composed of a phototransistor or the like for determining the presence or absence of a package and its package presence signal are transmitted and the actual tray standby path L ₆ has an empty space, A pusher 13 operated by an air cylinder is provided. When the worker inserts the package P into the package presence / absence discriminating device 12 and the empty tray is present in the actual tray standby path L ₆ , the tray T is sent to the actual tray standby path L ₆ by the pusher 13. And is stopped by the stopper 8.

The actual tray standby path L ₆ is also a gravity conveyor in which a plurality of rollers are juxtaposed in the same manner as the bypass path L ₄ and which slides down due to the gravity of the tray T. That is, it is inclined from the empty tray standby path L ₅ side at the high position to the carry-out path L _{2 at the} low position. The actual tray T that has transferred from the carry-in path L ₁ or L ₁ empty tray standby path L ₅ to the actual tray standby path L ₆ slides down there and is temporarily stopped by the stopper 8. Then, when the actual tray T does not exist at the position of the output device 3, the stopper 8 is lowered and the actual tray T is sent out to the carry-out path L ₂ .

As described above, the standby path in each unit 2 is inclined from the carry-in path L ₁ to the carry-out path L ₂ , and this is also a gravity conveyor that slides down due to the gravity of the tray T. In this standby path, a maximum of three actual trays T are stocked in two rows including the frontmost one being wound (in FIG. 1, only one unit 2 has package P and tray T). Is shown). Then, the tray T which advances along the carry-in path L ₁ is automatically put in the standby path of each unit 2 when there is an empty space. The details of the standby path in each unit 2 are entrusted to the above-mentioned prior application or Japanese Patent Application No. Hei2-130623 of the present applicant.

In the yarn winding machine 1 including the tray transporting device configured as described above, when the package in the yarn winding is exhausted and emptied or a break is found, the empty tray T is While being discharged to the carry-out path L ₂ , the standby path in the unit 2 is in a state where the actual tray can be taken in from the carry-in path L ₁ . On the other hand, the package P output by the output device 3 proceeds to the carry-in path L ₁ when the tray payout signal is output, and is taken in to the standby path in the unit 2 in the tray take-in ready state. Even if the loading fails, the actual tray T moves to the downstream end of the carry-in path L ₁ and transfers to the actual tray standby path L ₆ . Then, the actual tray standby path L _6- > carry-out path L _2- > standby path L _3- > output device 3-> carry-in path L ₁ is moved again. Further, the tray T that is determined to empty tray with the yarn presence determination unit 9 of the standby path L ₃ is discharged from the unit 2 to the output path L ₂ is sent to the empty tray standby path L ₅ by the pusher 11 from the standby path L ₃ The empty bobbin is removed there and replaced with a new full package P. Then, it is sent to the actual tray standby path L ₆ by the pusher 13 and temporarily stopped by the stopper 8. The actual tray T is sent from the actual tray standby path L ₆ to the carry-out path L ₂ by the pusher 13 when the actual tray T is not present in the output apparatus 3, and is transferred to the output apparatus 3 via the standby path L _3. It is sent and uttered. Therefore Failure to yarn end finding, the tray T is blocked to move in the switching lever 5 is introduced into the bypass passage L _4, and temporarily stock. When three such trays T are accumulated, an alarm is activated, the operator handles the tray T so that it can be ejected, and the tray T is returned to the standby path L ₃ .
