Description

[Detailed description of the invention] The present invention relates to a loading device for plate materials, and more specifically, the present invention is concerned with a loading device for plate materials, and more specifically, it takes out plate materials one by one after processing with a processing machine such as a punch press and moves them horizontally a certain distance. , relates to a device for stacking one after another in a predetermined position.

Conventionally, for example, with a numerically controlled turret punching machine, the plate material that has been processed is moved to one end of the processing machine, but the grip is released at that position and the process moves on to the next plate material. Normally, when it is done manually, it is taken out and stacked and transported, or when it is done automatically, it involves various inconveniences because it relies on the method of stacking the boards by sliding them over the previous stack of boards. be.

In other words, the burrs generated during punching process etc. protrude downward, and the edge of the plate has many unevenness, which causes scratches on the top surface of the stacked plates, which reduces the value of the product. Ta.

Omitted. Note that 32 indicates the maximum width and minimum width of the products to be carried out.

Let's move on to the explanation of FIGS. 3, 4, and 5.

As shown in FIG. 4, the above-mentioned unloading device 5 has wheels 37 that are rotatable around a horizontal axis guided by a lipped channel 33 appropriately attached to its long horizontal portion, and wheels 37 that are rotatable around a vertical axis. A gripping device truck 35 whose position can be adjusted in the left and right directions with wheels 39 is provided, and the other gripping devices 7 themselves can also be adjusted in position left and right on the gripping device truck 35. Further, the unloading device 5 is provided with an abutment 41 that protrudes rearward at the same height at the left end and at the position shown in the figure from the right, and a pusher bolt 43 is attached to the rear end so that the amount of protrusion can be freely adjusted. There is.

Next, the above-mentioned bearing wings 9 and 11 will be explained. First, regarding the left bearing wing 9,
A sliding board 4 is suitably fixed on the frame body 3 in both the front and rear.
5, the wing rotation device 13 is fixed to the bracket in line with a joint beam fixed on a bracket 47 that can be moved and fixed from side to side. It is provided so as to protrude horizontally from the beam 49. Reference numeral 55 is a knob for moving the bracket 47 left and right and fixing the position.

In the above explanation, the left side support wing 9 is
It will be understood that the position can be changed to the left or right depending on the width of the plates to be carried out and stacked together with 9, so that even wide plates as shown in FIG. 1 or narrow plates can be handled. There is also a fixing knob 55 in the front, which allows a bracket corresponding to the bracket 47 to be fixed by sandwiching the board from below the sliding board. Regarding the right side support wing 11, although the wing itself rotates, it does not change its position in the left and right direction, so the bearing 53 that supports the wing rotation shaft 51 and the right wing rotation device 15 are directly fixed on the frame. has been done.

Next, the left wing rotation device 13, which is best shown in FIG. 3, will be described in detail.

The wing rotation device 13 is a type of bearing, and has a structure that allows movement of the shaft in the thrust direction. That is, the portion that receives the wing rotating shaft 51 is the front large diameter portion of the stepped through hole provided horizontally above the bearing block 57, and is the portion of the bush 59 fixed to the block 57.

The wing rotation shaft 51 has, for example, 60 mm at its rear end.
A left-handed threaded shaft 61 with a large lead such as a millimeter is fixed concentrically, and the left-handed threaded shaft 61 is also attached to the bearing block 57.
1 is fixed.

The wing rotating device 15 on the right side has the same structure as the wing rotating device 13 on the left side, only the shaft 65 has a right-handed thread with the same lead, and the nut member 67 is also a right-handed threaded nut member. The rear ends of these left and right threaded shafts 61 and 65 are clamped and fixed to the inner rings of a pair of tapered roll bearings 69, and the outer rings of the tapered roll bearings are clamped to a shaft sliding member 71.

In the above explanation, when the shaft sliding member 71 is moved back and forth, the left and right wing rotating shafts 51 are integrally moved back and forth, and the left and right threaded shafts 61 and 65 are moved back and forth by the left and right threaded nut members 63 and 67. It will be understood that both rotate by the same angle in opposite directions.

Next is the spring box 17 described above. As best shown in FIG. An intermediate plate 79, which will be described later, is fixed by a bolt 77 passing through a slide bush 75 provided on the tube. 74 is a spring. The shaft sliding member 71 described above is
It consists of two upper and lower parallel bars 81 that extend to the full width of the device, and is sandwiched between the outer rings of the pair of tapered roll bearings 69, and slides and drives the wing rotation axis together with the tapered roll bearings. Near the position of the spring box 17, there is an intermediate plate 79 with a thickness of about half that connects the two upper and lower parallel bars 81. As is clear from the figure, when the unloading device 5 moves forward from the state shown in FIG.
Since the shaft sliding member 71 moves forward until the shoulder of the bolt No. 7 comes into contact with the slide bush 75, it is screwed into the left and right threaded nut members 63 and 67, and the left and right wing rotation shafts are rotated in this case, for example. You can see that it rotates so that what had been hanging down returns to a horizontal state.

Note that 83 in FIG. 5 indicates stacked products.

In the above configuration, the unloading device 5 is moved closer to the table 23 of the processing machine, the plate material on the table 23 is gripped by the gripping device 7, and then the unloading device 5 is moved away from the table 23. The upper plate is pulled out onto the left and right bearing wings 9,11 which are held horizontally, and is supported by the left and right bearing wings 9,11.

As described above, after pulling out the plate material from the table 23 onto the left and right support wings 9, 11, the holding device 7 releases the plate material, and the unloading device 5 is further moved away from the table 23.
When the pusher bolt 43 provided on the unloading device 5 is brought into contact with the intermediate plate 79 and further moved against the spring 74, the left and right support wings 9, 11 are rotated downward via the left and right wing rotation devices. , the plate material supported by the left and right support wings 9, 11 is dropped.

Therefore, by repeating the above-described operations, the plates can be pulled out one after another from the table 23 of the processing machine, and the plates can be stacked without causing scratches.

As can be understood from the description of the embodiments, the gist of the present invention is as stated in the claims for utility model registration, and as understood from the description, according to the present invention, By gripping the plate material with the gripping device 7 provided in the carrying-out device 5 and pulling it out onto the left and right support wings 9, 11, and rotating the support wings 9, 11 downward, the plate materials can be stacked without rubbing. It is possible.

In particular, in the present invention, the bearing wings 9, 11
The wing rotation device for rotating each of the wing rotation shafts 51 to which the wing rotation shafts 51 are attached is equipped with a conversion mechanism that converts the backward motion of the unloading device 5 near the retreat position into rotational motion of the wing rotation shafts 51.
Therefore, the rotation of the wing rotating shaft 51 for dropping the supported plate material is performed after the unloading device 5 has sufficiently retreated, and moreover, it is performed in conjunction with the backward movement of the unloading device 5 in the vicinity of the retracted position. Therefore, the timing of the falling of the plate material is accurate, and there is no need for a drive device for rotating the wing rotating shaft 51, which simplifies the configuration.

Note that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments by making appropriate changes.
