Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a terminal feeding device in an automatic terminal crimping machine that sequentially crimps each terminal connected in a row to the end of each electric wire.

(Prior Art) This type of automatic crimping machine crimps terminals T connected in a row as shown in FIGS. 5 and 6 to the ends of electric wires (not shown) while cutting them off one by one. Each terminal T has a connection distance a (Fig. 5).
and carrying strips b (FIG. 6). A conventional feeding device for such an automatic terminal crimping machine will be explained based on FIG. 7.

In the figure, an automatic terminal crimping machine 1 has a pair of lower mold 2 and upper mold 3, and the upper mold 3 moves up and down to crimp the terminal T to the end of the electric wire between them.
A terminal feeding device 10 is installed on the side of the automatic terminal crimping machine 1.
is provided with a feeding claw which is moved back and forth in conjunction with the automatic crimping machine 1 so as to intermittently propel the terminals T, and which is normally biased to lock at the rear of each terminal T. 11, and a terminal pressurer 12 which is always biased to press against one row of terminals T so as to prevent excessive propulsion due to inertia or the like of the rows of terminals T.

More specifically, the feed pawl 11 is supported by a main link 13 that can be adjusted to approach and separate from the automatic crimping machine 1, and is pivotable around a pin 14 on one end of the main link 13. ing. Then, the free end portion 11a enters and leaves the passage W of the terminal T on the automatic crimping machine 1. Further, the feed claw 11 is connected to the spring 1 on the main link 13.
5, it is biased counterclockwise in the figure, that is, in the direction of entering the passage W of the terminal T. The main link 13 is supported at its other end by a pivot pin 17 on a position adjustment piece 16 fixed to the automatic crimping machine 1, thereby being held in a predetermined position.
At the same time, it is urged by a spring 18 to rotate around the pivot pin 17 in a direction away from the automatic crimping machine 1. The spring 18 is supported by the end of a tension adjustment bolt 19 protruding from the automatic crimping machine 1, and its tension is adjusted. Further, the main link 13 has its own guide pin 20, and the pin 20 guides the main link 13 by sliding within the long hole 21 on the automatic crimping machine 1 side. Therefore, the feed pawl 11 rotates around the pin 14 and at the same time around the pivot pin 17,
It has a structure that allows for smoother feeding.

Next, the terminal pressurer 12 is supported by a lever 23 that rotates around a pin 22 on the automatic crimping machine 1, and the lever 23 presses the terminal pressurer 12 toward the path W side of the terminal T by a spring 24. biased in the direction. Further, the lever 23 has a convex portion 2 so that the terminal pressurer 12 can be fixed in a state separated from the passage W.
A latch (hook) member 25 is provided at 3a.
The latch member 25 is substantially locked at a predetermined location 1a of the automatic crimping machine 1.

In the automatic crimping machine 1 having the conventional feeding device 10 described above, when newly setting one row of terminals T in the passage W, first move the lever 23 to the spring 24 in order to move the terminal pressurer 12 away from the passage W. The latch member 25 is hooked to a predetermined location on the automatic crimping machine 1 by rotating against the pressure. Next, while holding the feed claw 11 away from the passage W with one hand, hold the terminal T with the other hand and insert it from the bottom of the terminal pressurer 12 to a predetermined position below the feed claw 11. conduct. Next, by releasing the feed claw 11 and returning the terminal pressurer 12 to its original position, the terminal T can be automatically fed. When replacing the terminal T in the passage W, the terminal pressurer 12 and feed pawl 11 are operated in the same manner, and the terminal T is replaced with one hand.

(Problems to be Solved by the Invention) As described above, when setting or replacing the terminal T in the conventional feeding device 10, one hand cannot be removed from the feeding claw 11, and the terminal T The problem arises that it is difficult to operate the machine because it has to be operated with one hand. In particular, after the terminal presser has been moved away and fixed, the terminal must be attached while lifting the feed pawl, which requires double operations, and the same is true when returning them to their original positions.

In addition, as in the crimp terminal processing machine disclosed in Japanese Utility Model Application Publication No. 55-75990, a lever-like lever for separating the terminal pressurer is extended, and its tip is engaged with the feed pawl in the retracted position. It has also been proposed to link the terminal pressurer and the feed pawl by lifting the feed pawl.

However, in this proposal, the engagement is released when the feed pawl is in the forward position, so
Can only be used when the feed claw is in the retracted position. If the feed pitch of the terminal changes and the retracted position of the feed pawl changes, it may not engage or collide unless it is replaced with a compatible one. Since there is no means to stop the terminal presser and the feed pawl that have been separated, the terminal must be held by hand, so the remaining one hand must be used to replace or set the terminal.

The present invention was developed to solve these conventional problems, and its purpose is to make it possible to set and replace terminals with both hands, and to make the work extremely easy with one operation. An object of the present invention is to provide a terminal feeding device for an automatic crimping machine.

(Means for Solving the Problems) The present invention includes a stop means capable of locking the terminal pressurer so that it is fixed in a state away from the path of the terminal when replacing or setting the row of terminals. The terminal feeding device has a terminal feeding device, wherein the feeding claw and the terminal pressurer are connected by a connecting member whose one end is connected to the feeding claw and the other end is connected to a lever for operating the terminal pressurer. When the terminal pressurer is fixed by the stop means in a state where it is connected and is kept away from the terminal passage, the feeding pawl is simultaneously pulled up and fixed by the connecting member so as to be separated from the terminal. This is a terminal feeding device.

(Function) When replacing the terminal to be supplied on the feeder,
Alternatively, when setting a new terminal, if only the terminal presser is moved away from the terminal path and fixed, the feed pawl is also automatically moved away from the terminal path and fixed, so the operator can only use one of the terminals. By simply performing the fixing operation, both can be fixed at the same time, making it possible to operate only the terminals with both hands.

(Example) The present invention will be described below based on an example shown in FIGS. 1 to 4. Note that the same reference numerals will be used to describe the same parts as in the prior art.

In FIG. 1, a terminal feeding device 1 according to the present invention is shown.
0a is equipped with a feed pawl 11 and a terminal pressurer 12 that are configured to perform the same functions as the conventional one, and the various mechanisms related to these are the same as the conventional one, so a detailed description thereof will not be provided. is omitted.

According to the present invention, when the terminal pressurer 12 is moved away from the passage W of the terminal, the terminal pressurer 12 and the feed pawl 11 are simultaneously moved away from the terminal in the passage W in conjunction with the terminal pressurer 12. The claws 11 are connected to each other by a desired connecting member 30. The connecting member 30 may be, for example, a link, but in this embodiment, it is made of a wire. One end of the wire 30 is fixed to the protrusion 23a of the lever 23 on the terminal pressurer 12, and the other end is fixed directly to the feed pawl 11. wire 30
The middle part of the main link 13 is guided by a nut-shaped tension adjustment block 31 screwed onto the tension adjustment bolt 19, and is substantially attached to the upper end of the main link 13, and is further connected to a wire attached to the main link 13. - Guided by a guide 32. Therefore, the terminal pressurer 12 is connected to the passage W.
When the convex portion 23a of the lever 23 is pushed down to move away from the wire 30, the end of the wire 30 is pulled and the free end 11a of the feed pawl 11 is pulled up from the passage W. Therefore, if the latch member 25 is locked in the predetermined position 1a of the automatic crimping machine 1 in this state, the terminal pressurer 12 and the feed pawl 11
are fixed at a position away from the passage W when both are jointly operated (the position shown by the imaginary line in FIG. 1). Note that the amount by which the feed pawl 11 is lifted from the passage W can be controlled by the tension adjustment block 31.

Hereinafter, with reference to FIGS. 2 to 4, an example of a method for replacing or setting the terminals T in the terminal feeding device 10a configured as described above will be described.

First, to explain the replacement work, FIG. 2 shows that the terminal pressurer 12 is activated and the terminal T in the passage W is
is pressed and the feeding claw 11 is locked to the rear of one terminal T.

Next, as shown in FIG.
In order to separate the terminal T from the terminal T, the lever 23 is rotated around the pin 22. As a result, the terminal pressurer 12 separates from the terminal T first, creating a gap as shown in the figure, but the feed pawl 11 is still locked to the terminal T.

Subsequently, as shown in FIG. 4, when the lever 23 is further rotated to lock the latch member 25 in the predetermined position 1a, the feed pawl 11 is also completely separated from the terminal T and fixed. In this state, the operator can use both hands to pull out one row of terminals T and replace them with another row of terminals.

When setting the terminals for the first time, the terminal pressurer 12 and feed pawl 11 may be set in the same manner as shown in FIG. 4. At that time, as shown in FIG. By bringing the terminal pressurer 12 closer to the passage W while pulling it backward, the free end 11a of the feed pawl 11 can be reliably locked to the rear of one terminal T.

(Effects of the invention) As explained above, according to the invention, the feed pawl is moved away from the terminal path in conjunction with the terminal pressurer and is fixed at the same time as the terminal pressurer, so these operations are easier. It only needs to be done once, and the operator does not have to keep lifting the feed claw with one hand when replacing or setting the terminal, and the operation is made extremely easy by using both hands.

However, regardless of whether the feed pawl is in the forward position or the retracted position, even if the feed pitch of the terminal changes and the retracted position of the feed pawl changes, this can be handled regardless of these conditions.
