Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention sequentially transports waste paper, which is compression-molded into a lump having a predetermined shape, horizontally from the exit of the press body, and is horizontally connected to the end of the transport. The present invention relates to a discharge device of a waste paper press machine for pushing and aligning by a push pusher at a right angle to the transfer direction.

<Prior Art> Conventionally, as a discharge device of a waste paper press machine of this type, for example, a block waste paper, which is sequentially pushed horizontally from an exit of a press main body as disclosed in Japanese Utility Model Laid-Open No. Sho 62-193996, is used as an exit device. On the belt conveyor that is continuously installed horizontally, and the horizontal movement is performed by separating and separating the lump waste paper that is discharged first and the lump waste paper that is discharged subsequently by the operation of this belt conveyor. , A transverse pusher that is reciprocally movable continuously in the orthogonal direction is provided horizontally at the downstream end of the belt conveyor, and the block waste paper transferred to the downstream end of the belt conveyer at a right angle from the belt is advanced by the lateral push pusher. There is a device in which the entire device is not elongated in the discharging direction of the block waste paper by pushing and aligning.

<Problems to be solved by the invention> However, in the conventional discharging device of the waste paper press, such scraps of paper tend to be loosened and fall off from the block waste paper during transfer. Between the belt-shaped plates that make up the belt and wind around the drive roller, causing the belt to meander, and as a result, the belt is easily damaged, and a shear force perpendicular to the operating direction acts on the belt of the belt conveyor when it is pushed by the lateral pusher. Therefore, there is a problem that the belt is apt to be damaged and malfunction occurs, which causes a reduction in the operating rate of the device for repair and replacement of the belt.

Further, since the downstream end of the belt conveyor intersects with the starting end of the pushing path of the lateral pusher, the lateral pusher must be installed in the air so that it does not come into contact with the downstream end of the belt conveyer. And the driving unit sandwiches the downstream end of the belt conveyor and projects to the opposite side of the feeding path, that is, to the outside of the transfer path of the lump waste paper by a large amount by the pressing stroke, and the entire apparatus becomes large in size. .

In view of such conventional circumstances, the present invention has an object to dispose a side-push pusher and a drive unit thereof along a transfer path of massive waste paper without using a belt conveyor.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above-mentioned problems is to provide a sliding surface on which the lower surface of the block waste paper is slidably contacted continuously with the outlet of the press main body. A hooking means that is detachably engaged with is provided reciprocally along the transfer path from the vicinity of the exit of the press machine body to just before the start end of the push path, and the lower end of the lateral push pusher is extended below the sliding surface to push the push path. It is characterized in that it is reciprocally movable by being linked to a drive unit embedded along the.

<Operation> According to the above technical means of the present invention, a step of engaging the block waste paper discharged from the outlet of the press main body on the sliding surface with the hooking means to move the block waste paper in the transfer direction, and removing the block waste paper By repeating the step of removing the hooking means and moving in the opposite transfer direction a plurality of times, the block waste paper is transferred to the front of the lateral pusher waiting in the retracted position and driven after the hooking portion is disengaged from the block waste paper. The bulk waste paper is pushed by advancing the lateral push pusher by the operation of the section.

In the figure, 3 is a stopper for overrun emergency stop.

Next, the operation of the discharge device of such a waste paper press will be described.

First, in the initial state, the hydraulic cylinder that constitutes the drive unit 1c of the latching means 1 is compressed to cause the hooking claw 1a and the moving table 1e.
Lateral pushing hydraulic cylinder constituting the driving portion 2c of the pusher 2 to stand the pusher surface 2a are extended to the starting end position of the pusher path C ₃ causes wait to start position of the transfer path C ₂ to.

In this state, when the block waste paper B is discharged from the outlet A ₁ of the press body A onto the starting end of the transfer path C ₂ of the sliding surface C ₁ , the hydraulic cylinder 1c of the hooking means 1 is extended to move the hooking claw 1a. A block of waste paper B that penetrates through the hole 1e _{1 of the} table 1e and projects above the sliding surface C ₁
The hook claw 1a and the moving table 1e move horizontally in the transfer direction to transfer the block waste paper B, and immediately after this is finished, the hydraulic cylinder 1c compresses and moves the hook claw 1a downward. The lumped waste paper B is removed and moved together with the moving table 1e in the anti-transfer direction.

At this time, the lower surface of the lumpy waste paper B that has been transferred has a through hole for the sliding surface C ₁ .
It does not move in engagement with the peripheral portion _{C 22, C 23, C 23} , C 24, C 24 of C ₂₁ in the counter-transfer direction.

Repeating multiple expansion and contraction of the hydraulic cylinder 1c described above, pusher path C ₃ to start the engagement position of the pawl 1a hook with respect to the lower surface of the bulk waste paper B is allowed to transfer to progressively transport direction moves the counter-transfer direction, i.e. retracted The block waste paper B is transported to the front of the pushing surface 2a waiting at the position.

At this time, the transfer time of the block waste paper B is the exit of the press main body A.
Since it is faster than the discharge interval of the block waste paper B sequentially pushed out from A ₁ , there is a gap between the block waste paper B discharged earlier and the block waste paper B discharged subsequently and separated.

Immediately after the lumped waste paper B arrives at the start end of the pushing path C ₃ , the catch claw 1a is disengaged by the compression of the hydraulic cylinder 1c, and the moving table 1e moves in the counter-transfer direction and moves away from the hydraulic cylinder 2c of the lateral pusher 2. forward the pusher surface 2a by compressing, pusher path transfer clot wastepaper B starting end of the pusher passage C ₃
Push to the end of C ₃ and align.

When pusher surface 2a reaches the end of the pusher path C _3, the pusher surface 2a by extending the hydraulic cylinder 2c returned to the initial state, thereafter, are repeated operation described above.

In the above-described embodiment, the drive unit 1c of the latching means 1 and the drive unit 2c of the lateral pusher 2 are configured by hydraulic cylinders, but the invention is not limited to this. For example, a pinion gear fixed to a motor and a rack may be used. The stopper 1 or the lateral pusher 2 may be horizontally reciprocated.

<Advantages of the Invention> The present invention having the above-described configuration has the following advantages.

A step of engaging the hooking waste paper discharged from the outlet of the press body on the sliding surface with the hooking means to move in the transfer direction,
By repeating the process of removing the hooking means from the blocky waste paper and moving it in the direction opposite to the transfer direction a plurality of times, the blocky waste paper is transferred to the front of the lateral pusher waiting in the retracted position, and the hooking portion is removed from the blocky waste paper. Since the block waste paper is pushed by advancing the horizontal push pusher by the operation of the drive unit after it is disengaged, it is possible to arrange the horizontal push pusher and its drive unit along the transport path of the block waste paper without using a belt conveyor. it can.

Therefore, compared with the conventional one in which the lateral pusher and its drive unit protrude significantly outside the transfer path of the block waste paper using a belt conveyor, even if a piece of paper loosens from the block waste paper during transfer, there is no malfunction and repair or repair is possible. The number of times of parts replacement is remarkably reduced, and as a result, the operating rate of the apparatus can be improved, and the entire apparatus can be downsized by the amount that the lateral pusher and its drive unit do not protrude from the transfer path of the block waste paper.
