Abstract

PURPOSE:To obtain a rational FTL by erecting a pallet at each machining station and transferring a work in sequence in the flexible transfer line FTL. CONSTITUTION:When a pallet 9 is mounted on the set pin group 8 of a slider 4 at the advance start point, it is shifted to the position of a station jig 2A by a rack pinion and positioned. In this case, an arm 10 is located below the pallet 9, and if it is rotated by a shaft 18, a worm 19, and a wheel 20, the pallet 9 is erected and machining on a work W is performed. During this time, The slider 4 is returned to the advance departure point, and after machining is completed, the arm 10 is reversely rotated, and the pallet 9 is mounted on the next pin group 8. Positioning, erection, and machining are performed in sequence at individual machining stations 2B, 2C by the reciprocating movement of the slider 4. Accordingly, a rational FTL can be realized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a workpiece conveyor that can be used extremely effectively in flexible transfer lines.

(Prior art) So-called FTL (Flexible Transf)
In machining using the Line method, a machining unit is installed at each machining station defined at a constant pitch along the line, and a machining unit is installed intermittently to position the workpiece relative to each machining station. It is equipped with a conveyor to send it to. In addition, a set pin that can move in a fire-promoting manner at the pitch is installed on the main body of the general conveyance machine, and when the workpiece 8 is placed on the conveyance machine, the workpiece is -H.
This is done by attaching the transfer pallet to the valet and mounting it on the front pin. Usually, the pallet is mounted parallel to the transport direction, that is, generally horizontally, and the workpieces are fed intermittently and sequentially processed by each processing unit. ,
The order in which each processing unit is arranged along the line is
It is determined based on the machining process of the workpiece, and in this case, the entire FTL process can be configured in block units consisting of 9M processes depending on the machining content.

[Problem that the invention seeks to solve]

By the way, depending on how this machining process is set up, FTL
Making the scale of the company larger than necessary is FTL
This is an important element in the composition. For example, when the workpiece is a vaporizer, the vaporizer usually has an extremely large number of parts that need to be machined, and therefore almost large-scale processing is required. Conventionally, such vaporizers are mounted on a conveyor via a pallet, the pallet being held in a horizontal position throughout the entire FTL process.

However, in such conventional FTL, the attitude of the vaporizer on the conveyor can only be fixed through the horizontal pallet. If the machining process in the standing posture is included, the machining process in the standing posture must be set separately from the F T L.

That is, in the conventional FTL, it is impossible to process a workpiece with the pallet in an upright position, and this has been a major problem in the configuration of the FTL. In view of such circumstances, the present invention
It is an object of the present invention to provide a conveying machine capable of processing blocks in an upright position during all processes.

[Means and effects for solving the problems] In the conveyor according to the present invention, as shown in FIGS. 1 and 2, station jigs 2A and 2B each have a column portion 2a and a receiving portion 2b on a base 1. ,...

2D are arranged in a row with edges P corresponding to the processing stations, and a slider 4, which is held between the column parts 2a of each of these jigs, is provided so as to be able to reciprocate by a distance of pitch P below the receiving part 2b. . On this slider 4, set pin groups 8A, 8B, . In one example of a machine, when it is mounted on the pin group 8A (FIG. 1), it is moved by a pitch P by the slider 4 to the position of the station jig 2A. At this time, the arm 10 pivotally connected to the column 2a of the jig 2A is waiting to be positioned below the pallet 9, and the arm 10 is further moved by the shaft 18 via the worm 19 and the worm wheel 20. Since it is rotated toward the receiving part 2b, the pallet 9 is made to stand up and is pressed against the receiving part 2b by the arm 10. While the workpiece W is being machined in this state, the slider 4 is returned to its original position (the starting point of the forward path), so the set pin group 8B
has reached the position of the station jig 2A (see Fig. 2), and after the machining is completed, the arm 10 is rotated in the opposite direction again, so that the pallet 9 is moved from the station jig 280 receiving part 2b to the arm 10. At the same time, it is separated and mounted on the center pin group 8B. At the same time, a new pallet is mounted on the set pin 98A from which the pallet 9 has already been removed, and by the forward movement of the slider 4, this pallet and the pallet 9 on the set pin group 8B are moved to the station jig. It is moved to the positions of station jig 2A and station jig 2B, and the same operations as above are repeated.

In this way, as the pallets 9 successively supplied to the set pin group 8A are sequentially fed to the set pin groups 8B, 8C, . Processing is performed.

〔Example〕

Hereinafter, one embodiment of the conveyor according to the present invention will be described based on FIGS. 3 to 5 and with reference to FIGS. 1 and 2. In the figure, 1 corresponds to a specific block on the FTL line. a base plate which should define a corresponding processing station;
2 is a station jig which has a concave shape formed by a pillar part 2a and a receiving part 2b and is arranged in rows at a pitch P on the base plate 1 corresponding to the machining unit (m); 3 is a station jig which is fixedly installed along the base plate 1; The guide rail 4 is connected to the guide rail 3 via the support member 5.
A slider (first
The position shown in the figure and FIG. 2 is taken as the starting point of the outward journey. ),
6 is a rank fixed to the slider 4; 7 is a pinion that meshes with the rack 6 and can be energized by a motor (not shown) to cause the slider 4 to reciprocate; and 8 is a set of four erected on the slider 4. and each cent pin group 8A, 8B,...
.

Set pins 9 constitute the BE (see Fig. 2); 9 is a pallet on which the workpiece 1lFIW is mounted in a predetermined position, positioned by a centrifugal pin 8 through a hole 9a, and mounted horizontally; Arms 12 are attached to the inside of the column 2a of the station jig 2 by pins 11 and can be positioned at the bottom of both sides of the pallet 9 on the slider 4 which is at the feed stop position with respect to the stage tongue jig 2. A guide pin aligned with the guide hole 9b and fitted so as to be able to protrude from the upper surface of the arm 1O by the elasticity of the spring 13; 14 is a stopper for the arm 10;
15 is pivotally supported on the arm 10 via a shaft 16 -fi15
a connecting rod having a pin connected to the lower end of the guide pin 12;
17 is a guide member that embeds the upper end of the guide pin 12 on the arm 10 via a connecting rod 15 when the arm IO is in contact with the stopper 14, and 18 is a guide member that can be rotated forward and backward by a drive motor (not shown), etc. By rotating the arm 10 via the worm 19 and worm wheel 20 which are connected to each other, the pallet 9 is erected and the arm 10 is rotated.
a drive shaft 21 that can be pressed toward the receiving portion 2b by
is the trilimiter provided between the shaft 1B and the worm 19, and 22 is the upright position of the pallet 9! This is a positioning pin formed on the receiving portion 2b that can fit into the positioning hole 9C of the left arm 9.

Since the conveyor according to the present invention is configured as described above, first, when the pallet 9 is mounted above the set pin group 8 on the slider 4 at the starting point of the outward journey (see Fig. 1), the slider 4 is pushed by the pitch P by the lever 6 and pin 7 to move the set pin group 8A to the position of the stage tongue jig 2A. The set pin 8, that is, the pallet 9 is positioned with respect to the stage run jig 2, but at this time, as shown in FIG. Next, when the arm IO is rotated by the shaft 18 in the direction of the arrow in FIG. 4, the guide pin 1 that was retracted into the arm 10
2 protrudes from the upper surface of the arm 10 due to the elastic pressure of the spring 13 and engages with the guide hole 9b of the pallet 9, whereby the pallet 9 is positioned with respect to the arm 10 and reaches the receiving portion 2b and abuts thereon. In this upright position, the pallet 9 is positioned in the stage tongue jig 2 by the engagement of the guide hole 9c and the positioning pin 22 of the receiving part 2b, and is also pressed from behind by the arm 10. Processing unif l-m for workpiece W
However, the machining can be performed with high precision without causing any positional deviation during the machining. In this case, if, for example, a malfunction occurs in the machining unit (m) and an excessive external force is applied to the workpiece W or the pallet 9, the triclimic 21 will be activated via the arm 10. Since the driving force of the shaft 18 is cut off by 8, the propagation of such external force is prevented from proceeding any further, thereby reliably preventing damage to the equipment. After the machining is completed, the pallet 9 is held in an upright position in the stage tongue jig 28 by the arm IO, but during this time the slider 4 has returned to the starting point of the outward journey and is again attached to the set pin group with respect to the stage tongue jig 2Δ. 8B is positioned (see Fig. 2), after which the arm 10 is moved in the opposite direction 1i by the noyaft 18.
Since the pallet 9 is rotated to i1 (arrow B in FIG. 4), the pallet 9 is separated from the receiving portion 2b force 1 together with the arm 10, and the arm 10 is moved through the stopper 9a that contacts the stopper 14 to the set 6 group 8b. It is mounted on a rack. In this way, one cycle of operation is completed, and when a new barre 9 is mounted on the set pin 8 on the slider 4 at the starting point of the outward movement, the slider 4 moves forward again by the pitch P. However, at this time, the pallet 9 mounted on the center pin group 8B passes 1 m below the receiving part 2b of the stage tongue jig 2A and moves to the next station. ? i in 2 B. The workpieces W attached to the respective pallets 9 placed on the stage tongue jigs 2A and 2B in this way are not subjected to the prescribed processing, respectively, and the set pins J are set in the same manner. 1.8
New pallets 9 are supplied one after another to A, and these are sequentially applied to set pin n8A.

8R, . . . and processed for each added ester. When the pallet 9 is mounted on all the set pin groups IIA, . I am forced to do it.

In this way, the pallet 9 and the workpiece W sent from the previous block in a horizontal position can be processed with the pallet 9 in the upright position at each processing station, and the workpiece W can be processed in the upright position at each processing station. is intermittently transferred on the FTL line at a predetermined pitch. that time,
The workpiece W can be positioned with high precision by sliding on the Steinzun jig 2 with respect to the processing unit m through the hole 9a of the pallet 9, the guide hole 9b, the positioning hole 9C, etc. Therefore, F
The TL groove is particularly advantageous. In addition, rational FTI can be achieved without unnecessarily increasing the scale of the facilities that make up FTL.
