Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is capable of taking out a horizontally supplied core material and transferring it in a slanting state to a tilted holding table, thereby saving labor in transferring the core material. The present invention relates to a core material supply device that can be realized.

[Conventional technology]

For example, a decorative frame a for forming a frame into which a painting p or the like is fitted is
Conventionally, it is formed by cutting a long base material into an appropriate length, and the base material a is a base material b for forming an outer frame as shown in FIG. 5 (a), for example. It is obtained by attaching a reinforcing core material c to the center and bending both side edges of the base material b along the core material c.

On the other hand, in order to attach such a core material c efficiently and accurately, for example, as shown in FIG. 5 (b), the core material c which is tilted and supported on the holding table is sequentially ground from its lower end. Material b
It is desirable to press it upward, and when carrying the core material c into such a holding table, a plurality of workers grasp both ends of the core material c which is horizontally supplied, and the core material c is supplied while being tilted. This was done by transferring from a shelf to a holding table.

[Problems to be Solved by the Invention] However, the conventional one in which the core material b is manually carried in to the holding table requires at least two workers, and since it is manual work, Productivity is inferior due to difficulty in supplying accurate core material. Further, since the core material is long and heavy, there is a risk in carrying it in. Especially, when the core material is tilted, an operator who holds the core material above the core material is forced to work on a step or the like at a high place. There is also the problem of poor safety.

The present invention is based on the use of a core material elevator, and can automate the supply of the core material to the holding table, thereby saving labor and improving safety, and thereby a core material supply device capable of solving the above problems. The purpose is to provide.

[Means for Solving the Problems]

The core material supply device of the present invention includes a supply shelf to which the core material is horizontally supplied, a processing machine that has a holding base that tilts and supports the core material, attaches the supported core material, and performs processing. A traveling frame that moves upward between the supply shelf number and the holding table, an elongated support frame having a gripping tool for grasping the core member on the lower surface, and a traveling frame that is attached to both sides of the traveling frame and is independent of each other. A core material elevator comprising two elevators while holding the supporting frames in a horizontal state and in an inclined state which is the same as the inclination angle of the holding table by raising and lowering the supporting frames respectively.

[Action]

In this way, the core material feeding device can independently raise and lower the support frames holding the core material on both sides of the traveling frame that moves upward between the supply shelf and the holding table, and the support frame can be placed in a horizontal state and an oblique direction. It is equipped with a core material raising machine provided with two elevators which can be held in a state. Therefore, the horizontal core material supplied from the supply shelf can be automatically transferred onto the inclined holding member, which can save labor and enhance the safety. Further, the core material supply device includes a supply shelf for horizontally supplying the core material, and a processing machine for taking out and processing the core material supported by the holding table. It is possible to process all of the above in a batch, which also helps improve productivity.
