Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package transfer device for taking a full package cut out from a package stock portion of a false twisting machine or the like into a package transfer means as it is, and transferring the package transfer means to the next step.

[0002]

2. Description of the Related Art Conventionally, such a package transfer device as described above is disclosed in Japanese Patent Application Laid-Open No. Hei 10-298834. According to this, the package that has been fully wound by the winding device of the false twisting machine is doffed and stored in the package stock section provided at the subsequent stage of the winding device, and is placed in the cutout standby position of the package stock section. The stocked package is cut out by a package cutout device (a device that sends out the packages one by one from the stock unit) provided on the machine side, and the package of the package transport unit that stands by facing the front of the package stock unit. It is transferred directly to the bearing. The winding device of the false twisting machine is generally composed of 36 weights arranged in a line in the longitudinal direction of the machine stand and arranged in three rows in the vertical direction. In the above-mentioned conventional apparatus, the package transport means is movably suspended and guided on a transport rail in front of the package stock section, and packages cut out from the three rows of package stock sections vertically. In addition, three package support portions are provided at upper and lower positions at heights corresponding to the respective package rows in the vertical direction of the package stock portion so that they can be received simultaneously.

[0003]

According to the above, according to the above-mentioned package transport means, the three rows of package support portions are provided at the height positions corresponding to the vertical rows of the package stock portion. Since the lowermost row of the package support portions of the stock portion is arranged near the floor, the height of the package transport means is tall, reaching the transport rail from a portion near the floor. Therefore, when the package transport means moves to the next process, it is necessary to constantly secure a large passage space through which such a tall package transport means passes, and when the passage space intersects with the worker passage. In such a case, the worker must constantly walk while paying attention to the travel of the package carrier, which hinders the traffic of the worker. In addition, since the lower end of the package carrying means is located near the floor, the worker needs to be constantly careful so that a work cart or the like does not enter the passage space.

Further, in the conventional device, three rows of packages are received vertically, so that, for example, packages of one row (36 pieces) in the longitudinal direction of the machine in the package stock section are received by the package transport means. In the conventional case, three units of package transport units having four columns per column and three columns vertically (that is, 12 columns in total) are provided in the longitudinal direction of the machine base. Then, the weight of the 36 full packages is dispersed over a relatively short distance of 12 weights in the longitudinal direction of the machine base, so that the load per unit length becomes relatively large, and the transport rail (the transport rail) If the ceiling is suspended from the ceiling of the building, the ceiling of the building must also be strong enough to withstand this, which is not preferable because it causes a rise in equipment costs. This becomes more conspicuous as the laying distance of the transport rail is longer. The present invention has been made in view of the above-described disadvantages of the related art, and
It is an object of the present invention to provide a package transfer device that does not hinder traffic in a factory such as a work cart, and that can reduce the load on a transfer rail (or a factory building).

[0005]

According to the present invention, a predetermined number of full packages are arranged in a line in the longitudinal direction of the machine base, and a plurality of full packages are stocked in a plurality of rows in a vertical direction. In a package transporting apparatus in which a package is cut out and the cut-out full package is held in a package transporting unit in front of a package stock unit, and the package transporting unit is transported to a next process, the package transporting unit includes the package transporting unit. It has a row of package receiving sections arranged at a pitch in the longitudinal direction of the full package of the package stock section, and the row of package receiving sections has a running height position and a plurality of rows in the vertical direction on the front side of the package stock section. The package receiving height position corresponding to each row of the formed package stock section Between, characterized in that is provided so as to be parallel to the elevation relative to the machine frame (claim 1).

According to this, the package transport means includes:
Since the packages in each row in the vertical direction of the package stock part are received in a single row, the load per unit length is smaller than in the conventional case that receives multiple packages in the vertical direction when comparing the same number of packages. In addition, the load applied to a stand, a transfer rail, and the like can be reduced. Also,
The package receiving section of one row receives the package at a position corresponding to each of the package rows vertically arranged in the package stock section, and then has a traveling height position such that a worker can walk below the package row. The traveling space required for the traveling is set at a high position far away from the floor surface, and as a result, the workers and the work carts You can easily move under the space. Specifically, a transport rail is arranged at a high position sufficiently separated from the floor so as to connect the package stock section and the next process, and the package transport means is suspended and guided on the transport rail, and the The number of package receiving portions corresponding to the full-row package in a row is provided, and the rail portion corresponding to the package stock portion is a lift rail, and the package transport means is suspended on the lift rail. In this state, the lifting rail is moved up and down by the lifting device (claim 2).

[0007] The lifting rail is connected between lifting bodies guided up and down by a plurality of vertically extending guide pillars, and the lifting body is lifted and lowered by a lifting drive mechanism including a lifting motor. (Claim 3). When the package conveying means is hung on the elevating rail, and the longitudinal position of the package in the package stock unit and the package receiving unit coincide with each other, a positioning device for positioning the package conveying means in the conveying direction is provided on the elevating rail. (Claim 4). According to this, at the time of transfer of the package to the package transport means, the package transport means does not move in the transport direction, and the package transfer is reliable. The cut-out device for cutting out a full package is configured to cut out a plurality of packages belonging to one row of the package stock section to corresponding package receiving sections at the package receiving height position at the same time (claim 5).
