Description

[Detailed description of the invention] The present invention relates to intermediate conveyance of plank material.

The intermediate conveyance is a conveyance device for delivering punched or stacked blanks one by one to a part of the feeder of the transfer feed. The present invention particularly relates to intermediate transfer when the distance between a plank coupling device and the next transfer device is large. Previously, there were pushers and magazine feeds as devices of this type, but they did not pass through blanks with complex shapes, and the parts that came into contact with the blank needed to match the shape of the plank. If the plank material was different, the plank material had to be replaced each time, and it lacked versatility.

The present invention provides an intermediate conveying device that eliminates these drawbacks. Hereinafter, an embodiment of the present invention will be explained in detail based on the drawings. In FIG. 1, a cylinder 2 is provided on a sliding portion of a press or a planking stage of the press that moves up and down, and its piston rod is connected to a piston of a cylinder 6 via a rack 3, a rack 4, and a rod 5. The cylinder 6 is fixed to a pin of the bed section 7 below the floor surface. The internal structure of Schilling 2 is shown in FIG. In FIG. 3, the rack 4 is installed in a casing 42 fixed to a device frame 41 that has been reinstalled on the floor so that it can slide up and down, and meshes with a pinion 8. Fourth
In the figure, a planetary gear 10 is rotatably supported on a support shaft 43 mounted on a casing 42, and is rotatably provided on an arm portion of a pinion 8. Yusei Gya 10
An eccentric pin 11 at the tip of is rotatably joined to a slider 12. The slider 12 is connected to the upper and lower grooves 13 of the slider 13.
It is slidably engaged with a. The slider 13 is guided by a guide rod 14 fixed to the casing 42. A pin 15 is installed in the center of the slider 13, and a rack 16 is installed at the other end of the pin 15. The rack 16 is provided through the casing cover 42a, and has a pinion shaft 17 rotatably held by the casing cover 423.
The transmission shaft 18 is connected to the transmission shaft 18 via a coupling 44. In FIGS. 5 and 6, the transmission shaft 18
A gear 19 is fixed to the center of a diamond frame 42, and meshes with a rack 20 which is held on the frame 42 by rollers 21 so as to be able to move back and forth. A pin 24 fixed to the upper part of the rack 20 connects with the slider 23 and transmits movement of the rack to the slider. The slider 23 has a plurality of upwardly directed adsorbed odors 22, and slides the surface of a guide rod 26 installed on the body 25 in the feeding direction.

In FIG. 5, the cylinder 27 is fixed to the body 25, and the internal structure of the cylinder 27 is illustrated in FIG. In FIGS. 7, 8, 9, and 10, a frog is screwed onto the lower end of the piston rod of the cylinder 27 for lifting and lowering the chute 30, and the frog is connected to a pair of levers 29, 29. An engaged groove is machined to slidably engage a pin fixed to the tip. The levers 29, 29
The base ends of the guide rods 26, 26 are supported by the shaft ends of a pair of guide rods 26, 26. Therefore, the levers 29, 29 swing due to the vertical movement of the piston rod of the cylinder 27, and the guide rods 26, 26 rotate. In addition, the levers 29, 29
An engaging pin is fixedly provided in the middle portion of the bracket 28, and the engaging pin slidably engages with a mating groove provided in the placket 28.
The swinging motion of the levers 29, 29 is transmitted to the vertical movement of the bracket 28. A pair of levers 29', 29' are mounted on the other shaft ends of the guide rods 26, 26.
Engagement pins are fixed at the ends of the levers 29' and 29', and the engagement pins slidably engage with the engagement grooves provided in the bracket 28', thereby causing the levers 29' and 29' to swing. The dynamic movement is transmitted to the vertical movement of bracket 28'.

The left and right brackets 28 and 28' have chutes 30 and 30 with four support rails at their upper ends.
′ are each fixed. Also shoots 30 and 3
Since the ends of the cylinder 0' are engaged, the cylinder 27 moves up and down as a body in response to the operation of the cylinder 27. In FIG. 5, both ends of the body 25 having the guide rods 26, 26 are connected to two left and right adjustment cylinders 3 fixed to the device frame 42.
It is fixed on top of 1. The body 25 is raised and lowered by the adjustment cylinder 31 to adjust the height of the blank material on the chutes 30 and 30' to the height when the fingers of the transfer feeder clamp it. The operation of the device of the present invention will be explained below.

In Figures 1, 2, 3, and 4, slide 1
When the rack 4 goes up and down, the rack 4 goes up and down, and the pinion 8 interlocks with the reciprocating rotation. The locus of the center of the partial D bin 11 is PQR in FIG. However, it does not necessarily move from P to R, but within this range. As the rack 4 reciprocates due to the notch of the cylinder 2, the PQ section increases or decreases, and the QR section conversely increases or decreases accordingly. Therefore, the cylinder 2 serves to switch the feed stroke between large and small. The PQ portion contributes to the rotation of the transmission shaft 18, and the Q
Since the R portion has play, the feed stroke of the blank material becomes longer or shorter depending on the length of the RQ portion. The cylinder 6 serves to straighten the rack 4 via the rod 5, prevent the rod 3 from bending, and absorb play in various parts of the connecting portion.

Now, when the eccentric pin 11 reciprocates between PRs, the slider 1
2, the slider 13 is guided by guide rods 14, 14 and reciprocates, and the rack 16 connected via the pin 15 also reciprocates, and the pinion shaft 17 and transmission shaft 18 that mesh with it also reciprocate. rotates back and forth.

As shown in FIGS. 5 and 6, when the transmission shaft 18 reciprocates, the gear 19 installed on it rotates reciprocally, and the rack 20 meshing therewith reciprocates and is fixed to the upper part of the gear. The slider 23 is guided by the guide rods 26, 26 through the pin 24 and moves back and forth, and the plurality of adsorbed odors 22 provided upward on the slider 23 are spread back and forth. On the other hand, in FIGS. 5, 8, and 9, the lifting action of the cylinder 27 moves the guide rods 26, 26 and lever 2
9, 29 and 29', 29' swing, and the left and right brackets 28, 28' engaged with the respective levers move up and down.

As the left and right brackets 28, 28' move up and down, the chutes 30 and 30', which have four rails fixed to the upper part of each bracket 28, 28', move up and down in synchrony. In order to make it easier to understand the transport structure in the main layer, the station positions where the blanks are sequentially transported are shown in Fig. 5, when the feed stroke is small (f), 1' → 0 →
m→W, and when the feed stroke is large (F), 1'→0'→m→W.

First, when the chutes 30, 30' are being raised by the raising of the Schilling 27 piston rod, a blank material is supplied to the position of station 1 or 1'. Next, cylinder 27
Due to the lowering of the chutes 30 and 30', the chutes 30 and 30' are lowered below the upper surface of the adsorbed odor 22, and the blank material is adsorbed by the adsorbed odor 22. At this time, the rack 20 has returned to the retraction limit on the left side of the figure. That is, the adsorbed odor 22-2 is at the 1st position, and 22-3 is at the 1st position.
' position, 22-1 has returned to the 0 position or 0' position and attracts the blank material. When the eccentric pin 11 moves from P to Q as the slide 1 descends in conjunction with the press, the rack 20
moves to the forward limit, and the adsorbed odor 22 moves to the forward limit while adsorbing the blank material.

FIG. 5 shows a state in which the adsorbed odor 22 has reached the forward limit on the right side. The blank material adsorbed at position 1 or 1' is transferred to position 0 or 0', and the blank material adsorbed at position 0 or 0' is transferred to position m.

In the advancing machine of the adsorbing odor 22, the slide 1 further descends and the eccentric pin 11 advances from Q to R, but the slider 12 is stopped, so the rack 20 and the absorbent tool 22 also continue to be stopped.

This stopped state continues until the slide 1 returns and rises and the eccentric pin 11 returns from R to Q. While this adsorbed odor 22 is stopped at the forward end, the chute 30 rises again to a position higher than the adsorbed odor 22, and receives the blank material transferred to the position m in the same manner as 0 or D'. . Next, the slide returns to top dead center, so the biased D pin 11 returns from Q to P'.
The slider 12 moves back and the adsorbed odor 22 moves backward (to the left in FIG. 5), but during this time the chutes 30, 30' maintain their raised state.

When the adsorbed odor 22 approaches the retreat limit, the blank material at the position m is clamped by the finger of the transfer device feed bar and is conveyed to the press via the next position W (feed stroke Ft). Although the slide 1 returns to the top dead center, the idle stroke of the sill 2 causes the rack 4 to stop without moving to the left from point P in FIG. during the idle stroke. At this time, new plank material is added to the empty station 1 or 1' on the chute 30.
supplied to the position. Next, the chutes 30, 30' are lowered by the cylinder 27, and the blank material on the chutes 30, 30' is received and loosened by the suction tool, which is stopped at the retraction limit. Thereafter, the blanks 1, 2, 1', and 0' are similarly sucked and moved forward, and the conveyance movement of the suction tool from the retraction limit to the forward position, that is, the feed stroke f or F, is repeated. Regarding feeding the plank material to the receding eye (position 1 or 1') of the adsorbed odor, align the position with the planking stage of the press and directly feed the punched blank material. Alternatively, the stacked blanks may be fed one by one by another feeding device. Also, when supplying a blank material to the 0 or 0' position without using the 1 or 1' position, the adsorbed odors 22-4 and 22-5 on the left end are unnecessary and can be removed from the pin 32. It has become.
In FIGS. 5 and 10, the chute 30 at the right end
Of the four protruding rails, the ones on both sides are used to feed the press's feed bar (
It is designed to be removable in case it gets in the way when clamping (not shown).

Furthermore, the protruding rule of the chute 30' corresponds to the feed stroke (F) of the transfer device from the m position to the press die.
This is to provide an idle station at position W when t) is insufficient. If the transfer device that carries out the plank material from the main loader is a two-dimensional (planar) feed, the top surface of the chute 30' will be at the height of the feed line, but if it is a three-dimensional (three-dimensional) feed, the chute 30'
The height of the feed line is a position higher than the top surface by the three-dimensional lift base.

Therefore, when the subsequent transfer device is used for both 2D and 3D feeding and switches from 2D to 3D, it will require 31 shillings.
Activate to lower the suction tool and sychute by the amount of lift. Among the adsorbed odors, 22-1.22-2, 22-3 are 22-1, 22-2, 22 when the feed stroke is large.
14 is used when the feed stroke is small, so unnecessary parts are detachable. Since the present invention has the above-described configuration, it is not necessary to replace any parts depending on the shape and size of the blank material, so it can be applied to various blank materials.

{o- The feed stroke can be easily changed by controlling the cylinder 2, and the stop time of the retraction limit of the adsorbed odor can be set.

The action of the sill 6 ensures the engagement of the racks 4, and also absorbs looseness at various parts of the connection.

8. Since the planetary gear mechanism is used, the conveyance operation is intermittent and smooth, that is, there is no impact at the forward and backward limits.

■ By switching the cylinder 31, it is possible to support so-called two-dimensional feeding and three-dimensional feeding of the transfer.
