DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts collecting apparatus for collecting parts produced by a machine tool such as a lathe, a molding machine and a press into a bucket.

[0002]

2. Description of the Related Art Parts produced by machine tools such as lathes, molding machines and presses are sometimes collected in buckets for each lot for management. As a conventional parts collecting apparatus for such a demand, for example, as shown in FIG. 7, a large circular container 51 in which a plurality of fan-shaped buckets 52 are housed over one circumference is exemplified. . The large circular container 51 is mounted on the rotating means 53, and the rotating means 53 rotates at a constant cycle to sequentially collect the components produced in the fan-shaped bucket 52. The rotation of the rotating means 53 is performed, for example, by counting a processing completion signal and reaching a set amount.

[0003]

In the conventional parts collecting apparatus, for example, when the fan-shaped bucket is enlarged in order to increase the capacity for storing parts, the outer diameter of the circular container accommodating the fan-shaped bucket is increased. This results in a large installation space requirement. In addition, since the fan-shaped bucket for collecting parts has a shape that is very unsuitable for distribution to the subsequent process as it is after collection of parts, it is necessary to eventually replace the bucket with a bucket suitable for distribution. is there.

Furthermore, when it is not desired to make a dent or the like on a part to be collected, a highly viscous liquid, such as oil, is put in the bucket at the time of collecting into a bucket, so as to mitigate an impact at the time of charging. However, this requires oil to be supplied to all buckets used for collecting parts, which causes problems in workability and safety, such as spilling of oil during handling.

[0005] Further, the biggest problem of the conventional parts collection apparatus is that the apparatus does not detect an empty bucket and a bucket whose parts have been collected. There is a risk that these components may be mixed.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a parts collecting apparatus using a bucket excellent in workability.

(Hereinafter, referred to as an “actual bucket”) on an apparatus main body base H for transporting the bucket T supplied from the loader unit A in the order of the component input unit B and the unloader unit C. The transport unit D is provided with four units.

The loader unit A will be described. The loader unit A is provided with a lifting means L having a pair of arms 1 that can be opened and closed and raised and lowered. The pair of arms 1 is slidably supported by a linear motion guide 2 and is opened and closed by a cylinder 3 located therebetween. The closed state of the pair of arms 1 is a state in which the upper end edge Ta of the bucket T is locked. The pair of arm units 1 is moved up and down by the cylinders 4 and 5 to three positions (see FIG. 2) of a mounting position X, a holding position Y, and a standby position Z. In this embodiment, a pair of arms 1 is stopped at three positions X, Y, and Z by projecting and retracting the two cylinders 4, 5 in combination to move up and down. The empty buckets T are supported by the guide 6 and can be stored in a vertically stacked state. In this embodiment, the empty bucket T is supplied from above the loader unit A.

FIG. 2 shows a mechanism in which empty buckets T stored in the loader unit A are placed on the rail unit 7 of the transport unit D one by one by the lifting means L in the order of (a) to (f). FIG. (A)
The description of the operations from (f) to (f) will be described later.

FIG. 3 is a perspective view showing a state in which the bucket T is mounted on the rail section 7. The upper edge Ta of the bucket T is placed on the groove 7 a of the rail 7 and is movable.

FIG. 4 is a plan view showing a transport unit D for transporting the bucket T. A cylinder 8 that operates in a direction parallel to the transport direction of the bucket T is installed,
A cylinder 9 operating vertically is mounted on a slider (not shown) of the cylinder 8 via a bracket 10. In this embodiment, rodless cylinders are used as these cylinders 8 and 9. An E-shaped hooking claw 11 is attached to a slider of a cylinder 9 that operates in a vertical direction. Claws 11a, 11 of the E-shaped hooking claws 11
b is provided with the width of the bucket T, and pawls 11c are provided at a small interval downstream of the bucket T in the transport direction. Slider 9a of cylinder 9 operating vertically

FIG. 6 shows an unloader unit C for storing the actual bucket T. Under the rail section 7 where the unloader unit C is located, a lifting means N for lifting the actual bucket T is provided. The guide 15 that supports the actual buckets T in a vertically stacked state is provided with two sets of support claws 16. The support claw 16 is elastically supported so as to be openable and closable. When the actual bucket T is lifted, it is elastically contacted with the upper edge Ta of the actual bucket T and opened. When Ta passes through the support pawl 16, it closes and locks the upper edge Ta of the bucket T. In this embodiment, the elastic supporting force of the supporting claw 16 is provided by the spring force of the spring 17. The actual bucket T can be taken out from the side of the guide 15 by opening the door 18 (see FIG. 1).

Further, in this embodiment, an oil tank 20 containing a highly viscous liquid, for example, oil 19 is provided below the center of the rail section 7 shown in FIG. It is supported so that it can go up and down. This oil tank 2
0 is the bucket T from the component tray 13 of the shutter means M.
This is used to relieve the shock when the component W is put into the device. When the oil tank 20 is used, the bucket T has at least a bottom formed of a mesh-like member (not shown), and the bucket T is stored in the oil tank 20 when the oil tank 20 rises. The oil 19 is filled.

Next, the operation of this embodiment will be described.

First, the empty bucket T is stored in the loader unit A (the state of FIG. 2A). When both of the cylinders 4 and 5 of the loader unit A protrude the pistons, the empty buckets T in the stacked state are stacked.
Comes down to the rail section 7 of the transport unit D (the state of FIG. 2B). The pair of arms 1 is opened by the cylinder 3, and the upper edge Ta of the lowest empty bucket T is placed on the rail 7 (the state shown in FIG. 2C). When the cylinder 4 draws the piston to the position of the upper end edge Ta of the second empty bucket T from the bottom in the stacked empty bucket T, the pair of arm parts 1 is raised (FIG. 2).
(D) state). The pair of arms 1 is closed by the cylinder 3 to lock the upper edge Ta of the second empty bucket T from the bottom (the state of FIG. 2E). With the pair of arms 1 holding the empty bucket T, the cylinder 5
Pulls the empty bucket T by 1
Only one feed is supplied to the rail unit 7 of the transport unit D, and again enters the standby state (the state of FIG. 2 (f)).

Only one empty bucket T supplied to the rail 7 is hooked by the hook 11 of the transport unit D, and the lower portion of the shutter means M provided on the rail 7 at the center of the rail 7. Transported to After the empty bucket T is transported to the center, the empty bucket T is left there, the catching claw 11 is raised by the cylinder 9 to stop the upper edge Ta of the empty bucket T, and the cylinder 8 is moved in the transport direction. It moves in parallel, and the hook 9 is lowered by the cylinder 9 to enter a standby state.

The part W produced by the machine tool is usually directly put into the empty bucket T at the center of the rail portion 7,
While the bucket T is being replaced, the component W
Is inserted, and when the exchange of the bucket T is completed, the empty bucket T is inserted from the shutter means M.

This state continues until the set number of parts W are collected, and the actual bucket T from which the parts W have been collected is brought into contact with the upper edge Ta of the actual bucket T by the hook 11c of the hook 11 in the transport unit D. The actual bucket T is pushed out and pushed out to the unloader unit C. At this time, the next empty bucket T is simultaneously locked by the hooks 11a and 11b and supplied from the loader unit A.

The actual bucket T conveyed to the unloader unit C is lifted by the lifting means N, and after the upper end edge Ta of the actual bucket T elastically contacts the support claw 16 and opens and passes, the support claw 16 It is stored in a state of being locked. The real bucket T is pushed up from below one after another and stored in the guide 15 of the unloader unit C.

To take out the actual bucket T, open the door 18 and take it out from the side of the guide 15.

Here, as a case where it is desired not to damage the produced parts W such as dents at the time of collection, the parts W are transferred to the bucket T.
If the bucket T is filled with a highly viscous liquid at the time of collection, for example, if the oil 19 or the like is filled, the impact at the time of charging can be reduced. Therefore, in the present embodiment, while the empty bucket T is located at the center of the rail portion 7 and the component W is being collected, the oil tank 20 is raised from below, and the bucket T is completely immersed in the oil 19. At this time, the bucket T
Since at least the bottom portion is formed of a net-like member, the oil 19 is filled in the bucket T. When the bucket T is exchanged, the oil 19 in the bucket T naturally escapes as the oil tank 20 descends, and the bucket 19 appears. However, if the used liquid is a sharp liquid, the subsequent liquid is used. This is preferable because the process does not cause oil immersion.

According to this embodiment, since the buckets T for collecting the parts W are stacked and stored, the occupied area may be small for the parts collection capacity as the parts collection device.

For example, since at least the bottom surface of the bucket T is formed of a net-like member, a high-viscosity liquid such as oil 19 is applied to each bucket T to prevent damage such as a dent when the component W is inserted. One oil tank can be used in common for all buckets without the need to insert the component W. Further, the component W can be directly taken to the cleaning process of the component W without refilling the component W.

[0028]

[Other Embodiments] In the above embodiment, which bucket T
No means is provided for determining which lots of parts W are collected in which lots. Therefore, a discriminating means, for example, a barcode is provided in the bucket, and the barcode is read by a barcode reader before the bucket T is stored in the unloader unit C or in front of the component input unit B. If T is determined in advance, it is possible to know which part and which lot is collected in which bucket T.

Further, if the bucket T in which the oil-filled parts W are collected by using the oil tank 20 is passed through the cleaning unit before being stored in the unloader unit C, it is necessary to perform cleaning in a post-process. Disappears.

[0030]

According to the structure of the present invention, since the buckets for collecting the components are stacked and stored, the area occupied by the component collecting device can be small for the component collecting capability, and the space can be saved. It is.

If the bucket is formed of a net-like member at least on the bottom surface, a high viscosity liquid such as oil is not put in each bucket to prevent damage such as dents when components are introduced. One oil tank can be used in common for all buckets, and furthermore, it is also possible to directly carry out the part washing process without refilling parts.
