Abstract

PURPOSE:To facilitate the initial bridging operation for a band-shaped material by axially supporting a pair of guide rolls arranged in parallel to the upper and the lower surfaces of the band-shaped material and in slant form in the direction of traveling, with a different phase in the vertical direction, between a pair of connecting plates which are rotatable around a horizontal shaft. CONSTITUTION:A pair of connecting plates 1a and 1b are arranged oppositely in parallel on the both sides of the traveling passage of a traveling transfer body (a), and said connecting plates 1a and 1b are rotatably arranged around the horizontal rotary shafts 2a and 2b respectively. Though a pair of guide rolls 3a and 3b are axially supported rotatably between the both connecting plates 1a and 1b, said guide rolls 3a and 3b are arranged in parallel to the surface of the band-shaped material (a) and in slant form with respect to the direction of advance of the band-shaped material, and the edge parts of the roll shafts 8a and 8b are supported onto the connecting plates 1a and 1b by a swivel block 9. Therefore, the band-shaped body (a) in straight line form can be bridged in nearly S-figure form onto the guide rolls 3a and 3b by synchronously revolving the both connecting plates 1a and 1b.

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 body of a rotary printing press and other various kinds of belt-shaped bodies in degrees Celsius.

Conventional examples of the parallel moving device for the traveling strip are shown in FIGS. 1 and 2.
To explain using Figures (A) and (B), the traveling belt-shaped body (
A pair of upper and lower guides arranged parallel to each other and arranged parallel to the upper and lower surfaces of α) and with different vertical phases, and at an angle with respect to the running direction of the running strip (α). It has a structure in which the running strip (α) is guided in a substantially S-shape as shown in the figure by upper and lower guide rolls (b□) (b2). , lower guide roll (bl), (b2) per running strip (
The amount of lateral movement in a) is F3n, and the inclination angle of the guide roll is α
0, when the roll embrace angle of the traveling strip (α) is β0, and the roll diameter is D, SR= M
The upper guide roll (b,) and the lower guide roll (
b2) When the respective roll diameters at K are equal and the roll embrace angle β0 of the traveling strip (α) is large, the lateral movement amount S2R is 2R=2SR, and the traveling strip (α) is on the upper side. Assuming that the distance from the point P leaving the guide roll (bl) to the point Q contacting the lower guide roll (h2) is L, the distance S'I that the traveling strip (α) moves laterally during this time is as follows: It can be expressed as SL = L
The structure is S282R+SL.

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 conveyance cable (not shown) is disposed 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 in a substantially S-shape. However, during the above-mentioned hanging operation of the strip by the conveyor cable, the strip is moved in parallel by the upper and lower guide rolls. The hanging arrangement operation 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 arranged in parallel to both sides of the conveying path of the traveling strip and within a parallel plane. a pair of connecting plates that are rotatably arranged opposite each other; and a pair of connecting plates that are arranged in parallel with the surface of the traveling strip and inclined with respect to the running direction of the traveling strip. It is characterized in that it is equipped with a pair of guide rolls arranged in parallel, a guide wheel for a band-like guide cable disposed on one of the connecting plates, and a drive mechanism for synchronously rotating both the connecting plates. The target is achieved by rotating a pair of guide rolls in a parallel arrangement. The object of the present invention is to provide a running belt-like parallel moving device which eliminates the above-mentioned drawbacks by improving the operability of winding and arranging the belt-like body between the guide rolls by means of a conveying cable. ,.

The present invention has the above-mentioned configuration, and connects a pair of guide rolls installed in parallel between a pair of connecting plates by a drive mechanism, with the pair of guide rolls vertically out of phase with respect to the transport path of the traveling strip. The strip guide rope placed on the guide wheel on one side of the plate allows the strip to be inserted linearly between the two guide rolls very easily, and the drive mechanism moves both connecting plates in parallel planes. When the pair of guide holes are rotated in parallel to each other in a synchronous rotation operation, the pair of guide holes are rotated to the S-shaped winding side.
The band-like body is placed around the guide roll in a substantially S-shape, and at the same time, the band-like body guide cable is placed over the guide ring, and both guide rolls move parallel to the band-like body. Therefore, the belt-shaped body can be placed over both guide rolls extremely easily and quickly by effectively utilizing the belt-shaped body guide cable, and the operation performance for mounting the belt-shaped body on the parallel moving device is significantly improved. .

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