Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a conveying jig pallet that carries workpieces to be assembled and travels on a base conveyor in an automatic assembly line or the like.

(Prior art) On an automatic assembly line, in the event of a failure or maintenance of an automatic assembly machine, the automatic assembly machine may be replaced manually6. Conventionally, this has been carried out using a conveyor jig on a base conveyor. It is difficult to secure space for manual work between the workpieces loaded on the pallet and the assembly mechanism of the automatic assembly machine, so space for manual work is provided upstream or downstream of the automatic assembly machine. Another method was to carry out the assembly work.

However, this method requires space on the base conveyor for manual work, and if there are many automatic assembly machines, the total length of the base conveyor becomes long, which may cause problems in terms of layout. Also.

Another method would be to provide a mechanism for retracting the assembly mechanism section of the automatic assembly machine from above the base conveyor, but this would result in a large-scale configuration of the automatic assembly machine, which would increase costs. becomes.

(Problems to be Solved by the Invention) As mentioned above, when trying to manually perform assembly work on a conventional automatic assembly line when an automatic assembly machine breaks down or is maintained, space for manual work is required on the base conveyor. In addition, there are problems in that the automatic assembly machine needs to be equipped with a retraction mechanism for the assembly mechanism. Therefore, the object of the present invention is to realize a conveyance jig pallet that can be handled manually by an automatic assembly machine without making any changes to the base conveyor or automatic assembly machine, and that is also the purpose of the present invention. .

[Structure of the invention]

(Means for Solving the Problems) The conveying jig pallet of the present invention has a turning pin protruding from a portion near one corner of the upper surface of the conveying pallet that is equipped with running wheels and runs on the running rail of a base conveyor. A sliding rail shaped like an arc centered on a pin is installed on the top surface of the transport pallet.

An assembly jig having a rectangular plate shape on which a workpiece to be assembled is placed and fixed has one longitudinal end bottom surface rotatably supported by the pivot pin, and the other end bottom surface is the top surface of the sliding rail. Configured to be supported.

(Function) When the conveyance jig pallet of the present invention is automatically assembled by an automatic assembly machine, the longitudinal direction of the assembly jig is maintained at right angles to the traveling direction of the conveyance pallet, so that the workpieces to be assembled can be assembled by the automatic assembly machine. When the automatic assembly machine is stopped, rotate the assembly jig around the pivot pin until its longitudinal direction is parallel to the traveling direction of the transport pallet, and maintain the assembly jig in that position. , the work to be assembled is pulled out from under the assembly mechanism section of the automatic assembly machine and assembled manually.

(Example) Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIGS. 1(a) and 1(b) show a conveying jig pallet according to an embodiment of the present invention. The transport pallet (1) has four running wheels (
6) and runs on the running rail (7) of the base conveyor (8). A turning pin (4) is provided protruding from a portion near one corner of the upper surface of the conveying pallet (1).

A sliding rail (3) formed in an arc centered on the pivot pin (4) is installed on the upper surface of the conveying pallet (1). The assembly jig (2) has a rectangular plate shape, and one longitudinal end bottom surface thereof is rotatably supported by the pivot pin (4), and the other end bottom surface is supported by the top surface of the sliding rail (3). and assembled on the transport pallet (1). This assembly jig (2) has a workpiece to be assembled (9) placed and fixed thereon. Further, a turning handle (5) is attached to the upper surface of a portion of the assembly jig (2) closer to the edge than the rotation center supported by the turning pin (4). In FIG. 1(b), (10) indicates an automatic assembly machine, and (11) indicates an assembly mechanism section of the automatic assembly machine.

Next, the operation of the conveying jig pallet according to one embodiment of the present invention constructed as described above will be explained.
), as shown in Figure 1(a), the assembly jig (2) should have its longitudinal direction perpendicular to the traveling direction of the conveyor pallet (1) on the base conveyor (8). maintained. In this state, as shown in FIG. 1(b) and FIG. 3, the work to be assembled on the assembly jig (2) (
9) is located under the assembly machine end (12) of the automatic assembly machine (10) and is automatically assembled.

When the automatic assembly machine (10) is not operating, as shown in Fig. 2(a), the assembly jig (2) is moved to the transport pallet (1) by the rotating handle (5) provided on the assembly jig (2). While sliding on the top sliding rail (3), insert the turning pin (4).
) to maintain the first assembly jig (2) in a state in which its longitudinal direction is parallel to the traveling direction of the transport pallet (1), that is, parallel to the traveling rail (7). In this state, as shown in FIGS. 2(a), (b) and 4, the work to be assembled (9) on the assembly jig (2) is attached to the assembly mechanism (11) of the automatic assembly machine (1o). Since the assembly mechanism section (11) does not cover directly above the work to be assembled (9), the operator (12) can easily perform the assembly work manually.

As described above, according to the conveying jig pallet of one embodiment of the present invention, it is possible to handle manually when the automatic assembly machine is stopped without making any changes to the base conveyor or the automatic assembly machine.

In addition, if all automatic assembly machines are suspended due to maintenance of the automatic assembly line, etc., all assembly jigs (2) should be removed as shown in Figure 2 (a).
b) and transport pallet (1) in the state shown in Figure 4.
By running the assembly line, the entire line can be operated by manual assembly work without being influenced by the machine purchasing section (11) of the automatic assembly machine (10).

〔Effect of the invention〕

As described in detail above, according to the present invention, a transport jig pallet is realized in which an assembly jig for placing and fixing a workpiece to be assembled can be rotated on a transport pallet, so that automatic assembly by an automatic assembly machine is possible. At times, the longitudinal direction of the assembly jig is kept perpendicular to the traveling direction of the conveyor pallet so that the work to be assembled is under the assembly mechanism of the automatic assembly machine, and when the automatic assembly machine is stopped, the assembly jig is kept perpendicular to the traveling direction of the conveyor pallet. The position is changed by turning so that the pallet is parallel to the traveling direction of the conveying pallet, and the workpiece to be assembled is pulled out from under the assembly mechanism part to the front, and assembly is performed manually. In this state, the assembly mechanism section does not cover directly above the workpiece to be assembled, so the assembly work can be easily performed manually. Therefore, without making any changes to the base conveyor or the automatic assembly machine, it is possible to handle the automatic assembly machine manually when it is stopped, and it is possible to eliminate the increase in the space of the conveyor line and the cost increase due to the addition of functions to the automatic assembly machine.
