Description

  The present invention is for, for example, manufacturing a pneumatic tire for an automobile, for placing and storing sheet-like members such as a carcass member and a belt member formed in a predetermined size on a plurality of stacked trays. The present invention relates to a sheet-like member storage device.

Generally, as a storage device for this kind of sheet-like member, the sheet-like member formed in a predetermined dimension corresponding to the tire size is held by the suction device, and the sheet-like member is arranged at a predetermined position by the suction device. Stacked in the vertical direction by placing the empty tray on the tray on which the sheet-like member is placed and placing the next sheet-like member on the empty tray by the suction device. A sheet in which a sheet-like member is placed and stored on each of a plurality of trays is known (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 7-256781

  However, in the sheet-like member storage apparatus, a placement space for stacking trays at the predetermined position, an empty tray space for stacking empty trays on which sheet-like members are placed next, and Since a storage space for storing a plurality of trays stacked up to a predetermined number at a predetermined position is necessary, for example, in order to prepare two tray groups in which sheet-like members are respectively stacked and stacked There is a problem that at least three spaces for placing the stacked trays are required, and a lot of space is required for storing the sheet-like member.

  In addition, when a plurality of trays stacked up to a predetermined number in the installation space are moved to a storage space, or when a plurality of empty trays are stacked in an empty tray space, a forklift is used. There is also a problem that a space for moving the sheet member is required, and that more space is required for storing the sheet-like member.

  The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to be able to store sheet-like members in a plurality of stacked trays, and to save space in the storage place. An object of the present invention is to provide a storage device for sheet-like members.

  In order to achieve the above-mentioned object, the present invention provides a sheet-like member storage device for placing and storing sheet-like members on a tray, and a plurality of trays that are stacked in the vertical direction and on which each sheet-like member can be placed. A first tray group, a second tray group that is arranged side by side with the first tray group and is stacked in the vertical direction and on which each sheet-like member can be placed, and the lowermost stage of the first tray group First moving means capable of moving the tray to the lowermost stage of the second tray group and second moving means capable of moving the uppermost tray of the second tray group to the uppermost stage of the first tray group are provided.

  Thus, the lowermost tray of the first tray group can be moved to the lowermost stage of the second tray group by the first moving means, and the uppermost tray of the second tray group can be moved to the first tray by the second moving means. Since it can move to the uppermost stage of the group, for example, by placing the sheet-like member on the uppermost tray of the first tray group, and moving the tray by the first moving means and the second moving means, The tray on which the sheet-like member is placed becomes the second tray from the top of the first tray group without changing the position of each tray group and the number of trays. Therefore, by repeating the placement of the sheet-like member on the uppermost tray of the first tray group and the movement of the tray by each moving means, without changing the tray position and the number of trays of each tray group, Sheet-like members are sequentially placed on each tray of the first tray group and the second tray group.

  According to the present invention, by repeatedly placing the sheet-like member on the uppermost tray of the first tray group and moving the tray by each moving means, the position of each tray group and the number of trays are not changed. Since the sheet-like member can be sequentially placed on each tray of the first tray group and the second tray group, it is not necessary to provide a space for placing the tray in addition to each tray group. Since it is not necessary to use an external device such as a forklift to move the tray, it is extremely advantageous for saving the storage space.
