JPS59108655A - Device for removing and conveying sheet roll - Google Patents

Abstract

PURPOSE:To avoid imparting a gravity shock to a sheet roll at its removal, by controlling the pull-up force of a sheet roll removing and conveying device to be at a prescribed value higher than the weight of vertically moving members but not higher than the sum of the weight of the vertically moving members and that of the sheet roll. CONSTITUTION:When wire ropes 9 are wound upwards by hoists 10, a carrying beam 5 is moved up toward the bottoms of sheet rolls R. When detection light between photoelectric tubes 13, 14 is intercepted by the sheet roll R, the hoists 10 are stopped and fluid pressure cylinders 8 are started to push up an upper frame 6 and pull up a vertically movable frame 3 holding the rolls R. The fluid pressure for the cylinders 8 is controlled to a prescribed value by a pressure regulator or the like so that the force for pulling up the frame 3 is not higher than the total weight of the sheet rolls R and vertically moving members 3-6. For that reason, the shock at the transfer of the rolls R onto the carrying beam 6 is reduced the instant the supports of winders are removed from the rolls.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing and transporting all wound up sheet rolls from a winding device.

The present inventor is the inventor of the sheet roll conveying device disclosed in Japanese Patent Publication No. 56-22773. The conveying device transports a series of sheet rolls wound up by a slitter-attached winding machine on a parallel beam, which is a revolutionary change from the conventional work of suspending and transporting each sheet roll from an overhead lane. This is a simplified version. However, when automating the operation of this conveying device, if the parallel beam that receives the sheet roll is too high, the core stuck in the core support and drive mechanism of the winding arm will be pushed up, causing a malfunction. Therefore, conventionally, when the beam approaches the lower part of the sheet roll m1 due to the detection light shining on the upper surface of the parallel beam, the beam stops rising and the core support is removed. In this case, therefore, an impact S occurs in which the sheet roll falls onto the beam, albeit over a very short distance. If the winding core is supported at both ends, the impact will be greater on the side that comes off first.
This effect could not be avoided, especially for sheet rolls made of thin and flexible resin films.

This invention solves the remaining problems of the above-mentioned sheet roll conveying system using parallel beams. First, to give an overview, it consists of a movable suspension stand that can be stopped above the take-up device, and a movable suspension stand that can be lifted and lowered from this suspension stand. It is equipped with a lifting frame that is suspended horizontally, and two sheet roll receiving beams that are horizontally supported so that they can be approached and separated while maintaining parallelism by a pair of opening/closing arms hanging from both ends of the lifting frame. , the lifting frame hanging device of the above-mentioned hanging platform is equipped with a lifting and lowering device and a control that can set the lifting force to an adjustable constant value that is greater than the weight of the entire lifting member and does not exceed the total mold amount of the lifting member and the sheet roll. and a sheet roll take-up device, wherein the constant value is a value that does not cause a gravitational impact to the sheet roll when the sheet roll is supported by the two beams and the supporting portion of the take-up device is removed. It is a removal and transportation device.

Embodiments of the present invention will be described with reference to the drawings.

Figure 1.2 shows an embodiment of the present invention, the main parts of which are a movable suspension stand mounted on a rail above the winding device, and a lifting frame 3 suspended horizontally from this suspension stand. , two sets of opening/closing arms hanging from both ends of this lifting frame 3,
Two sheet roll receiving beams 5 are horizontally supported so that they can approach and separate while maintaining parallelism.

The winding device shows only the upper part of its winding arm A. A rolled-up sheet roll is carried at the tip of arm A.

In this embodiment, the winding core support means by the winding arm A is the second
As shown in the figure, both ends are supported by what is commonly called a "pressing tip" C. The winding device is a slinter-type winding machine, and two sheet rolls 11 are placed on the receiving beam S side by side.

The rails lead from above the winding device to a destination for transporting the sorting rolls, for example above a packaging facility. The movable suspension platform λ has an upper frame 6 that can be moved up and down to some extent on top of a normal truck, moves along four vertical guide pipes 7, and has four hydraulic cylinders g on the suspension platform base frame. Supported. Lifting frame 3
is suspended from the upper frame 6, and in this case, the wire ropes 7 that hang the four corners of the lifting frame 3 are hoists (hoisting type) 1
The hoist 10 is suspended from a wire rope that reaches the upper frame 6 through the inner ring of the guide tube 7. Four hoists I
Since O performs the hoisting and unwinding operations in synchronization, the lifting frame 3
ascends and descends while remaining horizontal.

The lifting frame 3 has an opening/closing arm 4 hanging down at both ends (a link mechanism/l for opening/closing and a screw drive mechanism/2 for the opening/closing mechanism/2), but their explanation is omitted. It is also possible to use a circular arc shape q'.

In this example, the receiving beam S is a round bar, and a light emitting tube '1' and a light receiving part /3, /'If are attached to both ends of the upper surface of the rod.

The inventive device is operated as follows.

First, the suspension stand 2 is parked above the sheet roll H.

The lifting frame 3 is lowered by the hoist 10, the opening/closing arm q is opened, and the opening/closing arm q is rotated to the underside of the sheet roll R and stopped. When the sheet roll R approaches until it blocks the detection light between Kokantake /3 and /4', the hoist 10 is stopped by the detection signal.At the same time, the fluid pressure cylinder g is started and the upper The frame A is pushed up and moves to pull up the lifting frame 3 that grips the sheet roll Ri.However, the fluid pressure to the fluid pressure cylinder g is adjusted to a constant value by a pressure regulator etc. The upper blade has a gap exceeding the total mold size of the lifting member, sheath) and roll.

Therefore, when the fluid pressure cylinder starts, the receiving beam S does not make any visible movement after hitting the lower surface of the sheet roll R.
All that is required is to have the receiving beam S replace some of the dust on the sheet roll H that had been attached to the core support of the winding device. As a result, the moment the support on the winding device side is removed, the impact of the sheet roll R moving onto the receiving beam 5 is alleviated. The degree of relaxation is determined by the receiving beam by the pulling blade by the fluid pressure cylinder g! is proportional to the proportion of the weight of the sheet roll that is shared and supported in advance. If the entire weight of the sheet roll H is transferred to the metal receiving beam S, there will be no impact at all, but if the sheet roll R is pushed up by the receiving beam S, the sheet roll supporting portion on the winding device side will be damaged. Therefore, it is only necessary to reduce the impact to a level that does not pose a practical problem. Normally, it is better to divide the weight of the sheet roll R by dividing it into the receiving beam S in advance.
Since the head difference is zero even if the weight ρ-% is shared and the winder is removed from the winding device, the impact is significantly reduced when considering the conventional head difference.

In the above embodiment, the pulling blade is controlled by fluid pressure, and many fluid pressure control devices are commercially available and easy to operate. However, the means for controlling the pulling blade at a constant level is not limited to fluid pressure. That-
As an example, FIG. 3 shows an embodiment using a spring/3.

This connects the fluid pressure cylinder g in Figure 1.2 to the coil spring/S
In addition, the pressure regulator that prevents the fluid pressure from exceeding a certain value has been replaced with a limit switch/6.

In this case, even if the wire rope 9 is wound up and the receiving beam S hits the lower surface of the sheet roll R, there is no need to stop the wire rope 9 from being wound up.

When it hits the lower surface of the sheet roll R, the receiving beam 5 stops rising, and the upper frame B compresses the spring IS and descends instead. Since the spring reaction force is directly proportional to the amount of spring compression, the spring reaction force (
When the hoist (pulling blade) reaches the desired size, the limit switch 6 installed at the adjusted height operates to stop the hoist. Limit switch/A
acts as a pulling force control device.

The embodiment shown in Fig. 6 does not use the hoist 10 shown in Fig. 1.2, but uses one hoist (
Although it is illustrated as being operated by a circuit), the elevating and lowering drive mechanism of the elevating frame 3 attached to the upper frame 6 can be varied in various ways. Materials for hanging the elevating frame 3 on the hanging platform 2 include wire ropes, chains, links, multiple pipes, rack rods, and the like. The upper frame 6 may not be used at all, and each hanging member may be equipped with a winding cylinder g, a spring 15, and a limit switch/6.

Conventionally, the more powerful the transportation device for the sheet roll, which is a large and heavy object, the more difficult it is to receive the sheet roll from the winding device.
The problem was that we had to be careful not to push up the bottom surface of the sheet roll and damage the support part on the winding device side.For this reason, the receiving beam was stopped at a place where it did not touch the bottom surface of the sheet roll, increasing the impact when receiving the entire sheet roll. This invention has completely solved the problem.

In addition to the lifting and lowering device, the movable lifting platform has a new control device that can adjust the lifting blade to a constant value, so the support beam can be sufficiently pressed against the bottom surface of the sheet roll without fear of damaging the sheet roll support part of the winding device. Ran. The pulling blade of that receiving beam? Since the weight M of the sheet roll is distributed as appropriate before being removed from the winding device, the impact due to gravity upon removal is weakened to a practically sufficient level.

This eliminates the risk that precision-wound sheet rolls would deteriorate in quality during transportation.
