Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parallel movement device for a traveling belt-shaped body for parallelly moving and guiding a belt-shaped paper material of a rotary printing press and other various kinds of belt-shaped bodies.

A first example of the conventional parallel moving device for the traveling belt-shaped body
2A and 2B, they are arranged parallel to the upper and lower surfaces of the running belt-like body a and with different phases vertically, and at an angle with respect to the running direction of the running belt-like body a. It has a pair of upper and lower guide rolls b ₁ and b ₂ arranged parallel to each other, and the running strip a is formed into a substantially S-shape as shown in the figure by the upper and lower guide rolls b ₁ and b ₂ . It has a structure that guides you in the shape of
The amount of lateral movement of the running strip a per upper and lower guide roll b ₁ and b ₂ is S _R , the inclination angle of the guide roll is α°, the roll embrace angle of the running strip a is β°, the roll When the diameter is D, there is a relationship of S _R = π×D×tanα゜×β゜/360゜, and the upper guide roll b ₁ and the lower guide roll b ₂
The amount of lateral movement S _2R when the respective roll diameters D are equal and the roll embrace angles β° of the traveling strip a are equal is S _2R = 2S _R , and the traveling strip a is moving the upper guide roll b _1. If the distance from the point P where it leaves to the point Q where it contacts the lower guide roll _b2 is L, then the distance S' _L that the traveling strip a moves in the lateral direction during this distance can be expressed as S _L = L × tan α °. , and the total amount of parallel movement S of the traveling belt-like body a is structured to be S=S _2R +S _L .

Therefore, in the conventional parallel moving device for the traveling strip, in order to first arrange the strip on the upper and lower guide rolls in a substantially S-shape, one end surface of the upper and lower guide rolls is used. A conveyor cable (not shown) is arranged on the side in a substantially S-shape like the traveling strip, and the conveyor cable first guides the strip to the upper and lower guide rolls of the above-mentioned arrangement. Although the strips are arranged in an S-shape, when the strips are stretched by the conveyor rope, the strips are moved in parallel by the upper and lower guide rolls, so that the original strip shape is The above-mentioned hanging arrangement operation of the body is extremely difficult.

The present invention was developed in order to eliminate the above-mentioned drawbacks of the conventional parallel moving device for a traveling strip, and is a parallel moving device for a traveling strip that is disposed parallel to both sides of a conveying path and rotates in a parallel plane. A pair of connecting plates movably arranged opposite to each other, and a parallel arrangement installed between the two connecting plates and arranged parallel to the surface of the traveling belt-shaped body and inclined with respect to the running direction of the traveling belt-shaped body. It is characterized in that it is equipped with a pair of guide rolls, a guide wheel for a band guide cable disposed on one of the connecting plates, and a drive mechanism for synchronously rotating both the connecting plates. The present invention provides a running belt-like structure that solves the above-mentioned drawbacks by rotating a pair of guide rolls in a parallel arrangement to improve the performance of the conveyor rope in passing the belt-like object over both guide rolls. The present invention is characterized in that it provides a parallel displacement device.

The present invention has the above-mentioned configuration, and connects a pair of guide rolls that are installed in parallel between a pair of connecting plates by a drive mechanism and are arranged at different phases vertically with respect to the transport path of the traveling strip. A strip guide rope placed on a guide wheel on one side of the plate allows the strip to be inserted linearly between the guide rolls very easily, and a drive mechanism moves both connecting plates in parallel planes. When the pair of guide rolls are rotated synchronously to the S-shaped winding side in a state of parallel arrangement, the strip is arranged to be wrapped around the guide roll in a substantially S-shape, and at the same time the strip is guided. The cable is placed around the guide ring, and both the guide rolls are in a position to move parallel to the strip, so the strip conveying cable is effectively utilized to move the strip to the guide rolls. It can be easily and quickly strung and arranged, and the operational performance of mounting the strip on the parallel moving device is significantly improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

A first embodiment of the present invention is shown in FIGS. 3 to 6, and in the figures, a is the running direction of the running belt-like body, and b is the running direction of the running belt-like body a, and as shown in FIG. A pair of connecting plates 1a arranged parallel to both sides of the running path of the body a and rotatable about rotating shafts 2a and 2b in a parallel plane (perpendicular to the plane of the running strip body a in the figure). , 1b, and a pair of guide rolls 3a, 3b are rotatably installed between the connecting plates 1a, 1b, and both the guide rolls 3a, 3b are arranged parallel to the surface of the running strip a. The rotating shafts 2a, 2b are arranged on both the connecting plates 1a, 1b so as to be inclined (inclined by α ₁ °) with respect to the traveling direction A of the traveling belt-shaped body a.
It is fixedly installed in the center of a and lb.

Further, as shown in FIG. 4, the rotating shaft 2b of the connecting plate 1b is rotatably fixed by a bearing 6 provided on the support floor 5, while the guide rolls 3a and 3b are rotatably fixed by a bearing 7. The ends of the roll shafts 8a and 8b mounted on the connecting plate 1b are attached to the connecting plate 1b by a swivel bearing 9, and also on the connecting plate 1a side, the rotating shaft 2a is attached to the supporting floor by a bearing. The roll shafts 8a and 8b have a similar structure in which the other ends of the roll shafts 8a and 8b are mounted by swivel bearings.

Further, as shown in FIGS. 5 and 6, guide rings 10,
10 is rotatably disposed, and the guide rope 11 of the disposed band-like body is guided by the guide wheels 10, 10.

Furthermore, a drive mechanism (not shown) is attached to the connecting plates 1a and 1b, and the drive mechanism is comprised of a belt-shaped body a inserted between the guide rolls 3a and 3b and a guide rope 11

Both the connecting plates 1a and 1b are rotated synchronously in the direction in which the connecting plates 1a and 1b are wound in a substantially S-shape, that is, in the counterclockwise direction in the drawing.

The first embodiment of the present invention shown in FIGS. 3 to 6 has the above-mentioned configuration, and to explain the operation and effect, as shown in FIG. When the guide rolls 3a, 3b and the guide wheels 10, 10 are arranged with different vertical phases on the upper and lower sides of the transport path of the strip a, the guide rope 11 is arranged in a straight line, and the guide rope 11 is arranged in a straight line. This allows the strip a to be inserted in a straight line very easily into the middle of the guide rolls 2a, 2b and the guide wheels 10, 10 without contacting them. When 1a and 1b are rotated synchronously (counterclockwise as shown), the 8th

The guide cables 11
The guide rolls 3a, 10 are similarly arranged to be wrapped around the guide wheels 10, 10 in a substantially S-shape, and the guide rolls 3a,
3b moves the strip a in the direction of the arrow so that it is always kept in a parallel state during the rotation operation, and the parallelism and inclination relative to the strip a are maintained constant, resulting in the arrangement shown in FIG. 3. , the position is such that a predetermined amount of parallel movement can be secured, and the belt-shaped body a
can be hung and arranged extremely easily and quickly.

As shown in FIG. 7, after inserting the strip a into the guide rope 11 between the guide rolls 2a and 2b, as shown in FIG. If it is moved toward 3a and 3b, the placement of the strip a on both rolls becomes more accurate.
