Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a material supply device suitable for automatically supplying materials to processing equipment.

Various transfer machines have been developed and put into practice in order to automatically supply materials to processing equipment. If the material has directionality, it is necessary to feed the material into the mold of the sizing press equipment with the phase adjusted in advance to match the directionality of the mold. Since this is not always the case, a lot of innovation is required, and it seems that there are almost no satisfactory devices available in the past.

Therefore, the present invention aims to provide a material supply device suitable for processing equipment that particularly requires phase alignment. Specifically, the material supply device according to the present invention A phase adjustment station installed on the line is equipped with a sensor for determining the phase of the material, a centering device that positions the material at the center, a rotary table that supports and rotates the material, and a centering and rotary table device that moves the material together. A lift device for lowering and positioning, a phase adjustment device provided corresponding to the sensor, a grip device that can be opened and closed horizontally and parallelly to grip and feed the material lowered and positioned by the lift device, and an oil applicator having a lift table that can be raised and lowered to receive the material at a material delivery position and an oil spray nozzle disposed within the movement stroke of the lift table to supply the material to the next process; The main point is that it is equipped with the following.

Hereinafter, details of the present invention will be explained with reference to an illustrated embodiment.

First, in an example in which gear 1 as a "material" is automatically supplied from station A to station F on a pass line G as shown in FIG.
A material supply device 2 according to the present invention is provided at C, D, E, and F. Specifically, a phase adjustment device 3 is provided at stations C and D, a grip device 4 is provided at stations D and E, and an oil application device 5 is provided at stations D and F, respectively. They will be explained in order below.

The phase adjustment device 3 mainly includes a sensor 6, a centering device 7, a rotary table device 8, and a lift device 9. The sensor 6 is
In this embodiment, a "fiber sensor" is used, and a bent guide frame 10 is protruded from a station C, which serves as a "phase adjustment station" on the pass line G, and a fiber sensor projector is attached to it via a mounting bracket 11. 12 and a fiber sensor light receiver 13 are attached. Note that 14 indicates a fiber sensor amplifier. Such a sensor 6 detects the shape of the gear 1 in a non-contact manner and determines the phase of the gear 1 sent to the station C. Furthermore, if a sensor such as an image sensor is used instead of the fiber sensor, the shape can be memorized and compared with the detected shape to determine the phase. [See Figure 3].

The centering device 7 is for centrally positioning the gear 1, and is provided facing the station C from below. It also includes a shaft 20 whose lower end is connected to a pressure cylinder 19 via a bearing 17 and a bearing case 18. Note that 21 indicates a mounting bolt.

The rotary table device 8 supports and rotates the gear 1, and includes a rotary table 22 located outside the centering ring 16 and facing on the pass line G of the station C, and a drive stem 23 supporting the rotary table 22. It mainly consists of.
The drive stem 23 includes a pulley drum 26 supported by a bearing case 24 and a bearing 25 as a "rotational force applying means", and a first timing pulley 2 attached to the pulley drum 26.
7. A synchro motor 29 provided via a motor bracket 28, a second timing pulley 30 attached to the synchro motor 29, a timing belt 31 connecting the first and second timing pulleys 27, 30, etc. are provided. There is. In addition, 32 is a key, 33 is a keyway, and the drive stem 23 is connected to the rotational force applying means [specifically, the pulley drum 26
] It is possible to go up and down in the vertical direction.

The lift device 9 lowers the centering device 7 and the rotary table device 8 along with the gear 1 placed on the rotary table 22, and then returns and raises the entire device, and is fixedly supported by the base 34. The main component is a pressure cylinder 36 connected to the drive stem 23 via a connecting plate 35. The lower end of the drive stem 23 is supported by a bearing case 38 via a bearing 37, and the pressure cylinder 36 further supports the lower end of the bearing case 38. Reference numeral 39 in FIG. 4 denotes a pin, which is protruded from the side surface of the drive stem 23 and inserted into the elongated hole 41 of the pin cover 40 for stroke regulation. The length of the elongated hole 41 is the stroke of the pressure cylinder 36, that is, the length of the rotary table 22.
This restricts the amount of downward movement of the upper gear 1, and is made to correspond to the distance between stations C and D.

Next, the grip device 4 will be explained. In order to horizontally feed the gear 1 between stations D and E, this grip device 4 grips the gear 1 that has been lowered and positioned by the lift device 9 and transfers it to the waiting position of the "lift table" described below. Assuming that the position of the path line G between stations A, B, and C is on the first floor of a building, it is lowered to a position corresponding to the first basement floor [see Figure 2]. ]. Such a grip device 4 includes a pair of arms 45 having a grip 43 made of an elastic material at the tip and a link arm 44 at the rear end, and a pressure cylinder connected to the link arm 44 to open and close the pair of arms 45. 46, a pressure cylinder 47 for moving the pair of arms 45 forward and backward in the horizontal direction, a pair of guide bars 48 for forward and backward movement, and supporting the pair of arms 45 together with the link arm 44 and the pressure cylinder 46 while engaging with the guide bar 48; It also consists of a base 49 connected to the pressure cylinder 47 (see FIGS. 2 and 5).

The oil application device 5 is used to apply lubricating oil necessary for processing equipment (for example, a sizing press equipment) to the gear 1 in advance.
a chamber 50 for preventing oil dispersion, which partitions a chamber 50 for preventing oil dispersion; a lift table 51 that is movable up and down and arranged at the bottom of this chamber 50 to receive the gear 1 at the delivery position [station E] of the gear 1 by the grip device 4; This lift table 51
It consists of a pressure cylinder 52 for raising and lowering the gear between stations E and F, and a nozzle 53 for spraying oil onto the gear 1 on the lift table 51 within the movement stroke of the lift table 51. Furthermore, station F, that is, lift table 5
Gear 1 is connected to the processing device (not shown) in the raised position of 1.
Another supply device 54 for feeding the gear 1 is arranged separately so that the gear 1 can be freely fed to the next process.
See figure]. Note that 55 is a guide bar.

The operation of the material supplying device including such a phase adjustment device 3, grip device 4, and oil applicator 5 will be described below.

Gear 1, which is sent from station A to station B by a transfer device (not shown), is further transferred to station C on pass line G by a transfer pressure cylinder 56. Station C is a "phase adjustment station", and the gear 1 is first placed on the rotary table 22, and the centering 16 pushed up by the pressure cylinder 19 from below rises and the hole 15 of the gear 1 By intruding into the center, gear 1 is centered.
At the same time, synchronized motor 29 → second timing pulley 30 → timing belt 31 → first timing pulley 27 → pulley drum 26 → key 3
The rotational force is transmitted and applied in the order of 2→drive stem 23→rotary table 22, and the rotary table 2
2 rotates slowly with gear 1 still on it. During this time, the sensor 6 works, and the fiber sensor emitter 12 and the fiber sensor receiver 13 continue to detect the shape of the gear 1 in a non-contact manner. This is instantly determined and detected, and the rotation of the synchro motor 29 and rotary table 22 is stopped. This means that the "phase adjustment" is completed, and then the rotary table 22 is lowered while not rotating due to the action of the pressure cylinder 36, and the gear 1 is lowered and positioned from the station C to the station D. The position of the rotary table 22 at this time is as shown in FIG. 2, and the grip device 4 then functions. First, the pressure cylinder 46 is activated, and the pair of arms 45 are brought into a "closed" state, and the grip 43 at the tip is in gear 1.
[At this time, the centering ring 16 has already descended and is out of the hole 15 of the gear 1.] Next, the pair of arms 45 is moved by the drive of the pressure cylinder 47.
is guided by the guide bar 48 and moves in parallel horizontally to move gear 1 from station D to station E.

At the station E, that is, the material delivery position by the grip device 4, the lift table 51 is
is on standby, and if the pair of arms 45 are now in the "open" state, the gear 1 will be moved onto the lift table 51 without changing its phase. Then, by driving the pressure cylinder 52, the lift table 51 slowly rises with the gear 1 placed thereon, and during this time, lubricating oil is sprayed from the nozzle 53 all over the gear 1 to perform oil coating. Finally, the lift table 51 passes through the chamber 50 and stops at the upper limit position, making it possible to supply the gear 1 to the next process. is configured to send gear 1 to a processing device (not shown),
The gear 1 whose phase was adjusted by the previous phase adjustment device 3 is directly transferred to a processing device (for example, a sizing press device)
The phase required for this will be maintained.

As explained above, the material supply device according to the present invention adjusts the phase of the material in a predetermined direction while rotating the material (phase adjustment device), maintains the adjusted phase, and feeds the material. (grip device), and while the material is further transferred in preparation for the next process, such as feeding into processing equipment, the material is evenly coated with lubricating oil, and the material is kept on standby in preparation for supply to the next process (oil coating). This device is ideal as a feeding device for supplying materials with phase adjustment in advance.Furthermore, the phase adjustment described above is carried out while being supported and rotated by a rotary table, so even if the material is heavy, it is ideal as a feeding device. However, the phase adjustment can be done easily and efficiently, and after the phase adjustment, it is first positioned downward in preparation for oil application, then moved laterally, returned again, and raised while applying oil, so it is not difficult to apply oil. The line can be set shorter than the pass line, which is mainly used for horizontal feed, which would otherwise be a long line.In addition, the line can be set up so that it does not interfere with peripheral equipment or equipment near the pass line, and it is easy to use oil. It has a number of extremely advantageous effects, including the ability to prepare for processing by coating.
