Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for automatically loading strip-shaped materials onto a storage cart, and more specifically, to a device that automatically loads strip-shaped materials onto storage carts, and more specifically, a device that requires two types of loading alignment of the strip-shaped materials to be loaded. The present invention relates to a sometimes effective loading device for strip material.

[Prior art]

Conventionally, in extrusion lines for manufacturing tire treads, bias treads and radial treads are sometimes manufactured on one line.

In order to temporarily store these treads, a plurality of treads are normally stacked in an array on an album-shaped leaf, one end of which is swingably supported via a hinge in a storage vehicle, and stored in sequence.

However, since radial tread tires and bias tread tires have different shapes and properties, in order to increase loading efficiency, radial tires are usually separated in parallel, while bias tires are separated in two, with a portion of them overlapped.
Various loading methods are used.

When loading such a tread onto a trolley, there is no problem if it is loaded manually, but if it is loaded automatically by a machine, it cannot be done with one type of alignment loading device, so conventionally bias treads and radial treads were used. Similarly, they were loaded in parallel separation alignment.

As a result, the loading efficiency of the bias thread deteriorates, resulting in an increase in the number of storage carts, an increase in storage space, and an increase in the number of times the carts are transported.

[Purpose of the invention]

This invention was devised by focusing on such conventional problems, and its purpose is to be able to efficiently load two types of strip materials in one extrusion line, and to To provide a loading device for band-shaped materials that can be efficiently loaded onto a storage cart and can also be loaded in alignment without taking up a large storage space.

[Structure of the invention]

In order to achieve the above object, the present invention includes a multi-drive roller conveyor and a multi-belt conveyor that can be raised and lowered through cylinders between the rollers, and an orthogonal conversion conveyance device that changes the conveyance direction of a strip material at right angles. On both sides of this orthogonal conversion conveyance device, a parallel separation and alignment conveyance device for strip-shaped materials and a stacking alignment conveyance device are arranged in series so that they are each in a straight line. A feed conveyor is arranged in series on the delivery side of the strip material, and the tip of the conveyor for conveying the material that needs to be separated and aligned in parallel can be connected or disconnected to the feed conveyor, The rear end of the conveyor is connected to a parallel separating, aligning and conveying device via a reversing device and a conveying conveyor, and a strip material loading conveyor is connected to the discharge side of the orthogonal converting conveying device, and the orthogonal converting conveying device The gist of this invention is to automatically load the aligned strip materials sent from the storage vehicle onto the leaves of the storage cart via a loading device.

Loaded at 9. In addition, when the strip-shaped material W needs to be stacked and aligned, the cylinder 52 is operated and the material is raised above the tip 50' of the conveyor 50, so that it passes through the feed conveyor 40 and is transferred to the stacking, alignment and conveying device 20. The sheets are aligned in a stacked state, and transported to the loading conveyor 80 while maintaining the aligned state by the orthogonal conversion conveyance device 30, and loaded onto a predetermined leaf 99 of the storage cart 90.

Further, when the aligned strip material W is completely transferred to the orthogonal conversion conveyance device 30, the cylinder 33 is activated to raise the multi-belt conveyor 34, so that the material is received on the multi-belt conveyor 34. The loading conveyor 80 is installed at a height such that its upper surface is flush with the upper surface of the multi-belt conveyor 34 when the multi-belt conveyor 34 is raised, and its frame 35 is placed on the floor via the slide block 36. It is slidably supported by a fixed slide rail 37.

In front of the loading conveyor 80, a storage cart 90 is set on a table lifter 91. When the table lifter 91 finishes one loading operation, the next leaf 99 is unloaded by a leaf unloading device (not shown), so the loading height changes, so the loading height of the storage cart 90 changes. Leaf 9 to return
