Abstract

(57) [Summary] (Correction) [Purpose] A cylindrical work, such as a ball-point pen with a clip, having a protrusion on the outer circumference is placed on a pallet and is intermittently transferred so that the clip is at a predetermined position. Then, the work is positioned in the rotation direction and conveyed to the next label sticking device or hot stamping device. A conveyor 2 for intermittently transferring a pallet 3 having a concave portion 15a for mounting a cylindrical work having a protrusion on its outer periphery on its upper surface and having a punched portion communicating with the concave portion 15a from its lower surface. And a lifter provided with a work pushing-up bar 15 that moves the above-mentioned punched out portion of the pallet 3 stopped at a fixed position up and down.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, a cylindrical work having a protrusion on the outer periphery, such as a ball-pen with a clip, is intermittently transferred onto a pallet while being placed, and the clip is positioned so that the clip is in a predetermined position, and a price label is attached. The present invention relates to a work positioning / transporting device suitable for work such as wearing, drilling, and assembling.

[0002]

[Prior Art]

 2. Description of the Related Art There is known a device that has a conveyor on which a pallet is placed on the upper surface of a base, and that conveys the work placed on the pallet by intermittently rotating the conveyor by an intermittent rotation drive source.

A V-groove is formed in the longitudinal direction in the approximate center of the pallet. A writing instrument having a clip is placed in the V groove. In addition, a plurality of work units such as processing tools are attached to the upper surface of the base, and the writing tools that are intermittently transported are used to perform work such as making holes and attaching price labels.

[0004]

[Problems to be solved by the device]

 By the way, in the above-mentioned prior art, although the writing instrument is positioned in the lateral direction, it is not positioned in the rotational direction. Therefore, when the clip is used as a reference, a hole is made in the direction of 30 ° from the clip, or a hole is made in the direction of 60 °, and the positions of the holes in the rotation direction are scattered. Moreover, there is a similar problem when a label is attached.

[0005]

[Means for Solving the Problems]

 The present invention has an object to solve the above-mentioned problems, and has a recess on the upper surface on which a cylindrical work having a projection is placed, and a punched portion communicating from the lower surface to the recess is formed. The pallet is arranged on a conveyor for intermittently transferring the pallet at predetermined intervals, and a lifter for moving the pierced portion of the pallet stopped at a fixed position up and down is provided.

[0006]

【Example】

 Two chain type conveyors 2 are arranged in parallel on the upper surface of the base 1 via a base so as to be rotatable. Sprockets 4 are meshed with both ends of the chain type conveyor 2, and one of the sprockets 4 is connected to an output shaft of a rotary drive source 5 which rotates intermittently.

Further, the chain type conveyor 2 is provided with pallets 3 having trapezoidal recesses 3a formed at predetermined intervals. A writing instrument (work) 7 having a clip is placed in the recess 3a of the pallet 3.

Further, a lifter 8 is provided which forms a punch-out portion communicating with the recess 3a from the lower surface of the chain type conveyor 2 and moves the push-up portion of the pallet 3 stopped at a fixed position up and down. Has been done. The lifter 8 includes a drive source 10 having a speed reducer 9 fixed to a side surface of the base 1, a cam plate 12 fixed to an output shaft 11 of the speed reducer 9, and a cam plate 12 thereof. The work push-up rod 15 and the work push-up rod 15 which move up and down through the link members 13 and 14 by rotation and have a V-shaped concave portion 15a which is mirror-polished at the upper end by buff polishing are formed. It is composed of a spring 16 that urges downward. Reference numeral 17 denotes a working unit for making a hole or attaching a label on the writing instrument 7 placed on the pallet 3.

Next, the operation will be described. Writing instruments 7 are randomly placed on the pallet 3. Then, the writing instrument 7 is intermittently conveyed, and the writing instrument 7 is intermittently stopped on the upper surface of the lifter 8. Simultaneously with the stop, the lifter 8 rises, and the writing implement 7 is pushed up by the work pushing rod 15. Due to this pushing-up operation, the writing instrument 7 is rotated by its own weight so that the clip is at the bottom. This completes the positioning of the writing instrument 7 in the rotational direction. Then, the work is intermittently transferred to the next work unit to perform work such as drilling, but it is possible to perform work such as drilling at a constant angle with respect to the angle of the clip.

In the present embodiment, each work unit 17 and lifter 8 may have the same drive source 10, and each drive timing may be adjusted depending on the shape of the cam.

[0011]

[Effect of the device]

 The present invention has a concave portion on the upper surface for mounting a cylindrical work having a protrusion on the outer circumference, and a predetermined pallet on a conveyor for intermittently transferring a pallet having a punched portion communicating with the concave portion from the lower surface. Since it is equipped with a lifter that moves up and down the punched out parts of the pallet that are arranged at intervals and stopped in a fixed position, the work such as writing instruments is sequentially and intermittently transported by a simple mechanism. It is possible to position and position, and it is possible to always process and stick in a fixed position even in the case of punching and the like, and also in the case of sticking a label on which the price is printed.
