Abstract

PURPOSE:To permit an operator to select protective caps and taping to be effected automatically, by controlling the rotation of an engaging means and the upward movement of a support means based on the values obtained from the automatic measurement of the length and diameter of the work. CONSTITUTION:Movable frames 41 and 41' having a pair of oppositely positioned cap attaching plates 40 and 40' constituting an engaging means H are laterally slidably attached to both the sides of the upper part of a stand 36. The cap attaching plates 40 and 40' are provided with a vacuum mechanism for effecting a suction retention of a protecting cap to be set and the cap attaching plate 40 is so constructed as to be rotated by a gear mechanism 43 driven by a motor 42. The motor 42 for rotating the cap attaching plate 40 is controlled by an inverter based on the values calculated from measured diameter of the work a fed into a sequencer. After engagement of core c and the protective cap b, a taping means J is placed into operation to securely wrap with tape d along the boundary between the work a and the protective cap b.

Description

[Detailed description of the invention]

(Industrial Application Field) The present invention provides for the left and right sides of a cylindrical body (workpiece) formed by rolling a resin film, a piece of aluminum foil, and an Il material into rolls.
The present invention relates to a method and device for fitting and fixing a molded protective cap. (Conventional technology) When a resin film or paper is rolled up and shipped from a factory, the product is wrapped in an exterior material to protect it from dust. A packaging method is adopted in which the cap is fitted to the left and right sides of the roll product along with the core, and the boundary between the protective cap and the product is fixed by a j-shaped wrap to shield and protect the product from dust. ing. (Problem to be solved by the invention) In the conventional work of fixing the kettle mentioned above (t), all work is done by hand, and several people lift and knock down the product which has to be moved over a considerable distance. The actual situation is that the tape is wound by hand with a protective 8 cap attached. Therefore, the work of fixing the locking tube is time consuming and is also dangerous as it involves moving the hanging object. In addition, the diameters (outer diameters) of the products sent to fit the protective ant tubes vary, so the diameter of the product must be measured before fitting the -1 piece I. This method has the problem of requiring a lot of work. The present invention has been made in response to these problems of the conventional technology, and its purpose is to use a machine to carry in a workpiece (cylindrical body) and discharge it with a protective cap fixed. The purpose of the present invention is to provide a method that can save labor and provide a compact device that requires only a small installation area. (Means for solving the problem) 4-2 The method taken by the present invention to achieve the objective is as follows:

Hit the molded cooling cap and core corresponding to the indicated diameter on the fitting means, raise the fitting means to a predetermined height where the work is supported and held, and then move it toward the center in the width direction. Fit the core and protective cap on both sides of the workpiece. Thereafter, the workpiece descends while wrapping the tape around the boundary between the workpiece and the protective cap, and when it returns to the predetermined device, the tape winding is completed and the workpiece is not sent out in the unloading direction. In addition, the apparatus used to carry out the above method includes a loading means for receiving a workpiece transferred by a carrying means at the lower part of the outer side of one side of a frame formed in a substantially rectangular parallelepiped shape, and the like. A length measurement and width shifting means is installed to measure the quality of the workpiece and simultaneously position it for subsequent operations, and a lifter is installed to lift the workpiece in the F direction along the frame after the length measurement and width shifting is completed. A swing arm is installed to receive and pick up the workpiece lifted by the lifter and transfer it to the diameter measuring means provided on the inside upper part of the frame. On the other side of the frame, there is a pair of left and right mating stages in which the molded protective cap and core are inserted, a support means for mounting and supporting the workpiece, and a -F downward movement for the lower taping stage. A discharge means is provided at the lower limit position for discharging the workpiece after packaging is completed to the transfer means side, and a display section is provided near the frame body for displaying the measured diameter of the workpiece. shall be. (Operation) According to the above-mentioned means, the carried-in workpiece becomes 4v! Measurement of the length and diameter necessary for fitting and taping the protective cap, as well as positioning, are carried out before the protective cap is moved to a predetermined height and then lowered to a predetermined position below the frame. During this process, the molded protective cap and core are fitted on both sides of the workpiece, and the border between the workpiece and molded protective cap is wrapped with tape. When the workpiece reaches a predetermined position, it is discharged to the transfer means side by the discharge means, and the protective cap is removed. The fixed packaging is completed. (Example) Hereinafter, examples of the present invention will be explained based on the drawings.
