Description

Working trolley and yarn winding machine Technical Field One aspect of the present invention relates to a work carriage and a yarn winding machine. Background There is known a yarn winding machine including a winding unit group in which a plurality of winding units for winding yarn on a bobbin to form a package are arranged in an arrangement direction, and a doffing device provided so as to be capable of traveling in the arrangement direction of the winding units, for retrieving the package (the bobbin to be a full package) from the winding unit, and for supplying the bobbin to the winding unit. For example, patent document 1 (japanese patent application laid-open No. 5-17072) discloses a yarn winding machine including a plurality of bobbin storage sections (paper tube supply devices) and a conveyor that conveys bobbins (paper tubes) from the plurality of bobbin storage sections to a doffing cart. In the yarn winding machine having this structure, since a plurality of bobbin storage sections are provided, different types of bobbins can be supplied in accordance with each winding unit. Disclosure of Invention In order to meet the demand for producing packages of a plurality of types in the yarn winding machine, as described above, it is necessary to supply different types of bobbins to each winding unit. In this case, the doffing cart needs to store a plurality of bobbins in advance. In addition, regardless of the type, when the number of winding units is large and/or when the yarn is wound at a high speed in the winding units, the frequency of supplying the bobbin to the winding units is high. In this case, the doffing cart needs to store a large number of bobbins in advance. As described above, the doffing cart is required to be capable of coping with various forms. Accordingly, an object of the present invention is to provide a work carriage and a yarn winding machine that can cope with various forms. The work carriage according to one aspect of the present invention is provided with a magazine for holding a plurality of bobbins, and is capable of moving in an arrangement direction of a plurality of winding units and supplying the bobbins to the winding units, and the magazine includes a plurality of holding units for holding the plurality of bobbins, each of the plurality of holding units having an inlet portion through which the yarn feeding bobbin passes when the bobbin is introduced into the holding unit, and an outlet portion through which the yarn feeding bobbin passes when the bobbin is delivered from the holding unit to the operation unit. In the work carriage according to one aspect of the present invention, the plurality of storage sections of the yarn magazine include an inlet section through which the yarn feeding bobbin passes when the yarn feeding bobbin is introduced into the storage section, and an outlet section through which the yarn feeding bobbin passes when the yarn feeding bobbin is delivered from the storage section to the operation section. Thus, the plurality of holding portions hold the bobbin independently of each other. For example, bobbins of different types can be stored in each of the plurality of storage units. Therefore, the work carriage can cope with a plurality of varieties. In addition, in the case where the types of bobbins stored in the respective storing sections are the same, since the bobbins can be stored in the respective storing sections, the number of bobbins stored can be increased as a whole of the work carriage. Therefore, the work carriage can cope with the high frequency of supplying the bobbin to the winding unit. As described above, the work carriage can cope with various forms. In the work carriage according to one aspect of the present invention, the yarn pool may have two or more storage sections, and four or less storage sections. In this configuration, the work carriage can be prevented from being enlarged. In the work carriage according to one aspect of the present invention, the control unit may be provided to determine which of the plurality of storage units supplies the bobbin to the operation unit after the work carriage reaches the work position for the winding unit. In this configuration, since the holding portion for supplying the bobbin to the operation portion is determined after the work carriage reaches the work position, an appropriate bobbin can be reliably delivered to the winding unit. For example, if the bobbin is collected from the storage section at an earlier stage, the operation section needs to perform operations such as temporarily discharging the collected bobbin when the type of bobbin actually required after collection of the bobbin is changed. Or the work carriage stands by until the bobbin thus collected can be supplied to one of the winding units. In the work carriage according to one aspect of the present invention, since such an operation can be avoided, an appropriate bobbin can be efficiently delivered to the windin
