BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an end face polishing apparatus for polishing and removing burrs generated on the end face of a cut rod-like material.

0002

2. Description of the Related Art Bar-shaped materials such as steel pipes and bars are often used by cutting long materials into predetermined lengths. in this case,
As shown in FIG. 9, the cut material (1) cut by the cutting machine has burrs (3) on the cut surface (end surface) (2).
This needs to be removed.

An example of a device for automatically removing the burr (3) is disclosed in Japanese Patent Publication No. 14196/1983. In principle, as shown in FIG. 10, the end surface (2) of the cut material (1) is pressed against a rotating polishing wire brush (4) to polish away the burr (3).

0004

[Problems to be Solved by the Invention] In the above deburring work, in order to reliably remove the burr (3) of the cut material (1), the end surface (2) of the cut material (1) must be brushed with a wire brush (4). The cutting material (1) must be pressed with constant pressure and rotated so that its entire circumference comes into contact with the wire brush (4).

However, the device disclosed in the above publication has
Since the cut material (1) is rotated by its own weight while being transported and processed by being pressed against the wire brush (4), the cut material (1)
This requires a weight that can overcome the contact resistance of the wire brush (4) and a weight that can rotate under its own weight, and can only process long and heavy cut materials.

[0006] Furthermore, there is a device disclosed in Japanese Patent Publication No. 13073/1983 as a device for actively rotating the cutting material (1). However, since this device also rotates under its own weight, it can only process heavy objects.

[0007] The present invention aims to provide an end face polishing device that forcibly holds down and rotates a cut material, thereby making it possible to process light objects.

[0008]

[Means for Solving the Problems] The present invention provides an end face polishing device that conveys a cut material in a direction orthogonal to the width direction and polishes the end face of the cut material by pressing it against a rotating polishing wire brush during the conveyance. , is attached to a support frame installed above the conveyor that conveys the cut material and close to the polishing wire brush so as to be able to rise and fall freely, and circulates the belt endlessly along the conveyance direction of the cut material. a feeding means; a lifting means installed on the support frame for raising and lowering the feeding means; installed on the support frame;
A pressing mechanism is installed that includes a stopper means for variably adjusting the lowering position of the feeding means.

[0009]

[Operation] The above-mentioned end face polishing device transports the cutting material on a conveyor, and when polishing the end face, the feeding means is lowered by the elevating means of the pressing mechanism, stopped at a set height by the stopper means, and the belt The material to be cut is rotated and conveyed while being held down by the circulating belt, and during this time, the end surface of the material to be cut is polished by a polishing wire brush.

The stoppers (80) to (85) (two shown in the drawing) have different protruding amounts from the stopper plate (74). In addition, the air index (75) is the rotation axis (
77), and its output shaft (75a
) and a rotating shaft (77) are connected by a shaft coupling (86), and the rotating shaft (77) is intermittently rotated to stop a predetermined stopper at an upper position. Also, the guide rod (70) (
A stopper pin (90) is attached to the top plate (87) installed between the upper ends of 70) in correspondence with the stopper,
The lowering position of the feeding means (45) is determined by lowering the stopper pin (90) together with the feeding means (45) and hitting the waiting stopper (80) (Fig. 4
reference).

The stopper means (47) has an air index (
75) and place it above the corresponding stopper,
The distance between the lowered belt (51) and the conveyor (12) is made to be slightly narrower than the diameter of the cut material (11) to be held down. The control signal to the air index (75) is appropriately selected and inputted by the operator.

The pressing mechanism (17) is disposed close to the right side of the polishing wire brush (15), and is located close to the belt (5).
1) is inclined so that the lower side thereof is approximately parallel to the conveyor (12).

The other pressing mechanism (18) is disposed on the left side of the polishing wire brush (16), and is arranged on the left side of the polishing wire brush (16).
Since it has the same structure as 7), the explanation will be omitted.

During operation, the end face polishing device circulates each chain (24) (24) of the conveyor (12), rotates each polishing wire brush (15) (16),
Each guide roller (33) of the sorting conveyor (13) (14)
(33)..., (36), (36)... are rotated, and further the feeding means (45) of each pressing mechanism (17) (18) is lowered to a predetermined position to circulate the belt (51).

When the cut material (11) cut to a predetermined size by the cutting machine (10) is fed to the discharge conveyor (20) until it hits the stopper (21), the discharge plate (32)
) (32)... swing upward to transfer the cut material (11) from the discharge conveyor (20) onto the receiving plates (31) (31).... The cutting material (11) on the receiving plate (31) (31) is pushed by the attachments (25) (25)... provided on the circulating chains (24) (24)... and moves to the guide rail (23) ( 23)...It is transported forward while sliding on top.

When the cut material (11) being conveyed is placed on the guide rollers (33) (33)..., the guide rollers (33) (3

), the end face is aligned, and then sent forward. The aligned cut material (11) then enters between the circulating belt (51) and the conveyor (12), and is sent forward while being held down by the belt (51) and actively rotated. , a polishing wire brush (15) whose end face rotates between these two
It is rubbed and polished.

The cut material (11) with one end surface polished is then passed through the guide rollers (36) (3) of the sorting conveyor (14).
6)...It is placed on the top and moved to the right until it hits the positioning plate (44), the other end face is aligned and sent forward, and is held down by the pressing mechanism (18) and polished while rotating. The end face is polished with a wire brush (16).

The cut material (11) whose both end faces have been completely polished is sent further forward to the rotating index plate (
28) and is stored in the storage groove (29) of the conveyor (1).
2), and during that time chips and the like are removed by air blowing and discharged.

Furthermore, if the cutting material (11) can be sufficiently pressed and rotated only by the belt (51) of the pressing mechanism (17), the spring receiving plate ( 55), a pressing plate (56), a pressing means constituted by springs (60), (60), etc. may be omitted. Also, the above presser plate (
56) can be moved up and down, so even if the diameter of the cut material (11) changes somewhat, it can be held down sufficiently.

Furthermore, since the cut materials (11) after polishing can be taken out one by one using the index plate (28), the cut materials (11) can be discharged without stopping the transport conveyor (12), and chips can also be removed. It's easy to do.
