Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is capable of taking out a horizontally supplied core material and transferring it obliquely to an inclined holding table, thereby saving the labor of transferring the core material. The present invention relates to a core material supply device that can be used to

[Conventional technology]

For example, a decorative frame a for forming a picture frame into which a painting p etc. is inserted is
Conventionally, it has been formed by cutting a long base material into appropriate lengths, and the base material a is, for example, a base material for forming an outer frame, as shown in FIG. 5(a). It is obtained by attaching a reinforcing core material C to the center and bending both side edges of the base material along the core material C.

On the other hand, in order to adhere the core material C efficiently and accurately, for example, as shown in FIG. It is preferable to press the core material C onto the holder, and in order to carry the core material C into such a holding table, two or more workers grasp both ends of the core material C supplied horizontally, and tilt the core material C. This was done by transferring the material from the supply shelf to the holding table.

[Problem to be solved by the invention]

However, the conventional method of manually transporting the core material into the holding table requires at least two workers, and because it is done manually, it is difficult to continuously and accurately supply the core material. Productivity is poor. Furthermore, since the core material is long and heavy, transporting the core material is dangerous, especially when the core material is tilted, and the worker who carries the core material above the core material is forced to work at heights by climbing on a step stool or the like. There is also the problem of inferior safety.

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

[Means to solve the problem]

The core material supply device of the present invention includes a supply shelf to which core materials are supplied horizontally, a processing machine that has a holding table that tilts and supports the core materials, and that takes out and processes the supported core materials; a traveling frame that moves upward between a supply shelf and a holding table; a long support frame having a gripper on the lower surface for gripping the core material; A core material elevator consisting of two elevators is provided, while raising and lowering the support frame to hold the support frame in a horizontal state and in an oblique state that is the same as the inclination angle of the holding table.

[For production]

In this way, the core material supply device can independently raise and lower the supporting frames that hold the core material on both sides of the traveling frame that moves upward between the supply shelf and the holding table, and can move the supporting frames horizontally and diagonally. It is equipped with a core lift with two lifts that can be held in different positions.

Therefore, it is possible to automatically transfer the horizontal core material supplied from the supply shelf onto the inclined holding table, thereby saving labor and increasing safety. In addition, the core material supply device includes a supply shelf that horizontally supplies the core material, as well as a processing machine that takes out and processes the core material supported by the holding table.
The process from supplying the core material to processing it into the core material can be performed all at once, which also helps improve productivity.
