Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer-type processing device used to sequentially perform drilling and other processing on, for example, a carburetor for an engine.

As a conventional device of this kind, for example, Utility Model Application No. 59-78042
As seen in the above publication, there is a transfer line that intermittently transports vertically held pallets to one side in which workpieces are removably held on the sides of a hollow column that extends longitudinally in the lateral direction, and a plurality of pallets spaced at appropriate intervals on the line. It is known that a vertical machining unit is installed in parallel with the machining unit, and a pallet is positioned by a positioning means at a machining station on a transfer line directly below the machining unit to machine the workpiece. In this case, it becomes complicated to form a transfer line surrounding the outer periphery of the column, and it is also troublesome to attach and detach a workpiece from a vertically positioned pallet.

The purpose of the present invention is to obtain a device free of such inconveniences. On the side surface 2 of a hollow column 1 extending longitudinally in the lateral direction, pallets 10 in a vertical position for removably holding workpieces are intermittently placed on one side. A processing station 6 on the transfer line 5 directly below the processing unit 7 is provided. In an apparatus in which a pallet 10 is positioned by a positioning means to process a workpiece, the transfer line 5 is arranged in an upstream half 5a along one side of the column 1 and on the other side of the column 1. a downstream half 5b along the line;
An arm member 8a is formed by left and right conveyor lines 8, 8 along both end surfaces of the column 1, and one of the conveyor lines 8 is detachably attached to hold the pallet 10 from the back side, and the arm member 8a is horizontally attached. It is characterized in that it is formed in an attachment/detachment station 9 consisting of a turning motor 8c for turning the arm member 8a and a reversing motor 8d for reversing the arm member 8a.

An example of the present invention will be explained below with reference to the attached drawings.

In the drawing, reference numeral 1 designates a hollow column that extends longitudinally in the lateral direction, and the column 1 has mounting surfaces 3 and 4 at the lower and upper sides of the side surface 2, and on the lower mounting surface 3, the workpiece to be processed is mounted. A transfer line 5 for intermittently conveying a to one side is installed horizontally, on which a plurality of processing stations 6 are arranged at appropriate intervals, and a plurality of processing stations 6 are arranged on the upper mounting surface 4 facing each processing station 6. A plurality of vertical machining units 7 are arranged side by side at appropriate intervals, and the workpiece a is guided in one direction on the transfer line 5, and at each machining station 6, each machining unit 7 performs drilling and other operations. The processing is performed sequentially, and the transfer line 5 is divided into an upstream half 5a extending along one side 2a of the column 1, for example, the forward side 2a, and an upstream half 5a extending along the other side of the column 1. It is divided into a downstream half part 5b extending along the side surface 2b, for example, the rear facing side surface 2b, and is provided with respective conveyance lines 8, 8 extending between the two half parts 5a and 5b on the outside of each end thereof. Thus, the transfer line 5 as a whole is configured in an endless ring shape around the outer circumference of the column 1.
In other words, the workpiece a is first led to the upstream half 5a from its upstream end, subjected to various processing at each processing station 6, and then brought to the downstream end along the outer transport line. 8 to the downstream half 5b, and is guided over the half 5b and subjected to various processing at each processing station 6, and at the downstream end of the transport line 8
At this time, a station 9 for attaching and detaching is prepared in the middle of the line 8, and the workpiece a can be exchanged with a new one at the station 9. That is, the workpiece a is loaded and unloaded at the station 9.

To explain in detail what is shown in the figure, the transfer line 5 has a pair of upper and lower fixed fixed surfaces 11a that support a pallet 10 in a vertical position that removably holds the workpiece a, and that has an inner surface 11a that supports the pallet 10 slidably in the lateral direction. It consists of guide rails 11, 11, and a transfer bar 12 that reciprocates along these to feed the pallet 10, and in the illustrated one, the upstream side of the transfer line 5 is shown clearly in FIG. A plurality of the processing stations 6 are disposed in the half section 5a, and one reversing station 6a for inverting the pallet 10 is disposed between them. The processing station 6 is provided with the pallets 10 as shown in FIG.
The guide rail 11 is fixed by pressing from the back side of the
A pair of upper and lower clamp cylinders 13, 13 are provided to position the pallet 10 on the inner surface 11a of the pallet 11, and each reversing station 6a holds the pallet 10 from its back side and rotates the pallet 10 at 90 degrees or 180 degrees.
A reversing means 14 is provided for reversing the degree of reversal, so that the reversal causes the workpiece a on the pallet 10 to be selected with the surface to be machined next facing upward.

Furthermore, as shown in FIG. 3, each machining unit 7 is equipped with a drill or other tool 7d that extends downward from a machining head 7c on a slide table 7b that is moved up and down by an operating cylinder 7a, and is driven by a motor 7e located above it. The processing head 7c is equipped with at least two of the tools 7d, making it a multi-axis head, and the index motor 7
The two tools 7d can be selectively brought to the operating position by switching and rotating them using f.

Furthermore, each of the above-mentioned conveyance lines 8 is shown in FIG.
As clearly shown in the figure, an arm member 8a that removably holds the pallet 10 from its back side is supported by a shaft 8b at the root, and is rotated by a motor 8c above the arm member 8a, and thus the pallet 10 is It is arranged so that it is transferred from one of the two halves 5a, 5b to the other. It should be noted that on the left side line 8 in the drawing, a station 9 for attachment and detachment is interposed between the lines 8 as described above.

In the illustrated embodiment, a piping duct 15 is provided above the column 1 and extends along the column 1, and a large number of pipes for guiding operating fluid are accommodated in the piping duct 15.

To explain its operation, a workpiece a to be processed is detachably held on a pallet 10 and introduced into the upstream half 5a of the transfer line 5 from the upstream side. Half part 5
a, and is positioned on the inner surface 11a of the fixed guide rails 11, 11 by the clamp cylinder 13 at each processing station 6, and processed by each processing unit 7 sequentially. It is guided to the upstream side of the downstream half 5b of the transfer line 5 via the conveyance line 8, and is then guided along the half 5b to be sequentially processed by each processing unit 7 at each processing station 6. and is taken out from the downstream end to the outer conveyance line 8. Thus, the work a
Since this is obtained in a predetermined processed state, it can be replaced with the next workpiece a and the same processing can be applied to it, and this process is sequentially repeated.

In this way, according to the present invention, the transfer line 5 is laterally divided into an upstream half 5a along one side of the longitudinal column 1, a downstream half 5b along the other side of the column 1, and a column 1. A transfer line 5 endlessly connects the outer periphery of the column 1.
is formed, making it easy to transport the workpiece in one round, and during the round transport, the workpiece can be processed in various ways in each processing unit 7, and the transport line 8
One side of the pallet 10 is formed into a detachable station 9 consisting of an arm member 8a that detachably holds the pallet 10 from the back, a turning motor 8c that horizontally rotates the arm member 8a, and a reversing motor 8d that reverses the arm member 8a. , pallet 1 in vertical position
Even in case 0, the workpieces on the pallet 10 are turned over at the loading/unloading station 9, so that the workpieces can be easily loaded/unloaded.
