Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention is applicable to various industrial automatic processing machines such as transfer presses, including various materials, parts, products, and processed metal. When supplying molds and jigs to the operating part of the machine, or receiving from the operating part and storing them, these items can be held in parallel in a state where they can be quickly attached and detached depending on the work contents. Revolving storage cabinet.

(Prior Art) Conventionally, as this type of rotary control shelf, as shown in FIG. 4, a pair of sprockets 20 and 20 are installed at the upper and lower ends of the machine frame, and a link is provided between both sprockets 20 and 20. With chain 21
It is known that the tray 23 for suspending an object to be transported is hung on the pin 24 at the tip of each link 22 and a horizontal holding guide 25 is provided for maintaining the posture of the tray 23 and preventing swinging. Has been.

(Problems to be solved by the invention) However, in the above-mentioned conventional organizing shelves, the horizontal holding guide for guiding the tray along the oval orbit is related to the pin connecting the link of the chain and the tray. The guide is cut, and in fact, there is no guide in this part, and the tray may shake or tilt in the middle, so the stability of the article placed on the upper surface of the tray is very poor, and therefore, There is a problem in that it is necessary to provide a device for immovably fixing the articles placed on the upper surface of the tray by some method, and it is impossible to handle articles such as glass that are not susceptible to shaking.

The rotary organizer of the present invention was developed in order to solve the above-mentioned problems, and its purpose is to provide an article placed on the upper surface of a tray (article carrying member) without special fixing means. However, the original satellite movement mechanism provides a new rotary shelving unit with a support function that allows it to rotate while moving horizontally along a circular trajectory that keeps the loading posture of the article unchanged from beginning to end. Especially.

[Structure of Invention]

(Means for Solving Problems) The organization of the organizing shelf that achieves the above-mentioned object is such that a pair of left and right discs face each other and rotate on the outer peripheral surface of a fixed support shaft that is horizontally installed in the center of the machine frame. It fits as much as possible, and an appropriate number of rotation support shafts are arranged at an equal division angle at a position close to the outer peripheral edge between both discs, and an article carrying member is mounted on the shaft. Intermediate shafts are arranged at equal intervals along the circumferential direction with the same radius between the fixed support shaft of the plate and each rotation support shaft, and the fixed transmission wheel fixed to the fixed support shaft and the rotation fixed to the rotation support shaft. An intermediate transmission wheel fitted to the peripheral surface of the intermediate shaft is interposed between the transmission wheel and the rotation ratio between the transmission wheels so that each rotation spindle is negative while the disk makes one rotation in the positive direction. It is characterized in that it is set to rotate once in the direction.

(Exemplary Examples) The structure and operation procedure of the rotary storage shelf according to the present invention will be described below in detail with reference to the drawings of the embodiments. FIG. 2 shows an example of a cabinet that can be supported and stored so that it can be fed and received.

Reference numeral 1 in the drawings is a fixed support shaft that is provided horizontally across the center of the machine frame 2, and an article mounting member 3 corresponding to a shelf plate is attached to the outer peripheral surface of the shaft end of the fixed support shaft 1. A pair of discs 4, 4 serving as a rotating body for rotating are rotatably fitted so as to face each other on the left and right, and a tooth body 5 of a spur gear serving as an input gear is engraved on the outer periphery of the disc 4. The power of the motor 6 with a cyclo speed reducer is transmitted from the output gear 7 of the motor to the tooth body 5 of the spur gear through the intermediate gear 8 of the drive unit, and the disc 4
Is rotated by a required angle at a predetermined reduction ratio.

Next, reference numeral 9 is an appropriate number (eight in the drawing) of rotary spindles arranged at equal angular intervals in a position near the outer peripheral edge of the disc 4 and rotatably fitted thereto. An article mounting member 3 that serves as a tray (shelf plate) in the axial direction is connected between the rotary support shafts 9 and 9 facing the same phase of the circular plates 4 and 4. Further, reference numeral G ₁ in the drawings denotes a fixed transmission wheel provided on the flange portion 10 at one end of the fixed support shaft 1, and G ₄ denotes a rotation transmission wheel fixed to the rotation support shaft 9. The same number of intermediate shafts 11 as the rotational support shafts 9 are provided on the line connecting the rotational support shafts 9 at equal intervals along the circumferential direction of the same radius, and fixed transmission wheels are provided at both ends of each intermediate shaft 11. Intermediate transmission wheels G ₂ and G ₃ that work with G ₁ and the rotary transmission wheel G ₄ are installed. In the case of this embodiment, spur gears are used as a power transmission medium in each of the above-mentioned transmission wheels G ₁ , G ₂ , G ₃ , G ₄ , and the disk 4 is fixed by the power of the motor 6 to the fixed support shaft 1. When the peripheral surface of is rotated in a predetermined direction (counterclockwise in the drawing), the rotational movement is from the fixed transmission wheel G ₁ to the intermediate transmission wheel G ₂ and
It is transmitted to the rotary transmission wheel G ₄ via G ₃ , and each rotary transmission wheel G ₄ is
While revolving in the same direction as the disk 4, the satellite rotational motion is performed in the direction opposite to the revolving direction (clockwise). At that time, in the case of the present invention, the rotation ratio of each of the transmission wheels G ₁ , G ₂ , G ₃ , G ₄ is such that while the disk 4 makes one revolution (revolution) in the forward direction on one circumferential surface of the fixed support shaft. , Each rotation support shaft 9 is set to rotate exactly one revolution (rotation) in the negative direction.

When the disk 4 is rotated under such a condition, the rotation of the article mounting member 3 connected to the rotation support shaft 9 causes the fluctuation of the phase accompanying the revolution to occur in the opposite direction of the rotation support shaft 9 due to the rotation ratio. Since it is automatically corrected by the rotation motion of the article, the article W such as the exchange mold mounted on the member 3 does not seem to rotate at all when viewed from the outside, and is always horizontal. Since it can be rotated while maintaining its posture, there is no risk that the article mounting member will rock or tilt and the article will fall without special fixing means.

In this case, the set value of the rotation ratio changes depending on the number of teeth and the diameter of each transmission wheel, the number of gears, etc., but suppose that the diameter (PCD) of each transmission wheel is G ₁ = D ₁ , G ₁ = D ₂ , G _{If 3} = D ₃ and G ₄ = D ₄ , then It is sufficient to set so that the algebraic expression of is satisfied. In the case of the cabinet shown in the embodiment, D ₁ = 500 mmφ, D ₂ = 200 mmφ, D ₃ = 100 m
Since mφ and D ₄ = 250 mmφ, substituting this into the above algebraic formula, Therefore, the rotation ratio of the above embodiment is a proper numerical value,
In this relational expression, the number of teeth of each transmission wheel may be substituted instead of the diameter, and the diameter and the number of teeth of each transmission wheel can be freely calculated and set as long as the above conditions are satisfied.

In the above embodiment, each transmission wheel G ₁ , G ₂ , G ₃ , G ₄
, A spur gear is used as the power transmission medium, but a chain and a sprocket, a V belt, a timing belt and a pulley, or a combination of these and a spur gear is used instead of the above gear. It can also be realized.

Further, in the case of the present embodiment, an exchange die W for a press machine is placed and stored on the article holding member 3, and when the die W is correctly moved to the front and rear of the disc 4, a fixed support is provided. Driven by a fluid pressure cylinder 12 installed in the middle part of the shaft 1, the mold W at that position is transferred to the working part of the machine, or the mold W discharged from the working part is received. However, the rotary shelving unit of the present invention is not limited to the above-described embodiment, but can be freely applied to the sorting and storing of other articles.

〔The invention's effect〕

As described above, the rotary organizer according to the present invention is used in various industrial automatic processing machines such as transfer presses, in which various materials, parts, products, working dies, jigs and tools, etc. Even when these articles and article loading members are not fixed when they are supplied to or stored in the operating section, the original satellite motion mechanism prevents shaking and tilting, and keeps the article loading attitude from beginning to end. Since it has an excellent support function that can move along a circular locus that is held horizontally without changing, a special fixing device or fixing means is used regardless of the shape and material of the objects to be organized. Instead, these articles can be organized and stored for easy access.
