Abstract

PURPOSE:To enable a machine itself to be formed in a small size and reduce its manufacturing cost, by forming the machine from a pair of rollers in small diameter juxtaposing steering rollers concurrently used for adjusting upper side tension. CONSTITUTION:A belt tensioning means, when it actuates a piston rod 20a in its extending direction, lifts a supporting frame 15 to apply a suitable amount of tension to a sanding belt 18 by raising its tension. While a tilt actuating means, repeatedly deflecting in a longitudinal direction an axial core of rollers 17a, 17b in small diameter through the supporting frame 15 by extending and contracting a piston rod 22a, causes the sanding belt 18 to perform its required motion of track running. In such way, a machine is formed by a pair of the rollers 17a, 17b in small diameter juxtaposing the tensioning and track running roller means, enabling weight of the machine to be reduced while its required height to be decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a belt sangu with one head and one running head fM.

Referring now to FIG. 1, a conventional belt running device (to explain, this device has a drive roller 12' and an idler roller 714' installed below the base frame 1σ). At the same time, a large-diameter tension roller 17' with a large diameter tension "llf)1" is disposed on the upper side, and each roller is provided with a roller 17' that surrounds one frame 10'. IC sensor: / 7' Ingbel l-1, 8' is suspended, and the Zandink belt 1 is
It operates so that a part of 8' faces the straight material path, and performs the required grinding or polishing process on the corrugated material.

Here, the mounting frame 10' on which each of the above-mentioned roller means is mounted receives their weight, and since it is constructed in the form of a cantilever, it has a large rigidity (width dimension x height dimension)
must be such that Φ1t1 can be defined, so this frame 10' should be enclosed! Tonte Sanding Belt 18
In order to cross the river, the diameter of the steering roller 17' must be made considerably large.

When the diameter of the steering roller 17' increases, the bearings and support frame for receiving the roller also increase in size, and therefore the cylinder 20 must be mounted within the mounting frame 10'. , etc., and the disadvantages caused by this are compounded, and as a result, the configuration of the traveling device has to be made larger and more complicated. In addition, the only solution to the above problem is to increase the height of the mounting frame 10' to accommodate each part, and the large diameter roller and A.
Because of this, the 11-meter machine itself had to be large, which caused the problem that the production cost had skyrocketed.

The present invention has been made by focusing on the above-mentioned problems.
It is an object of the present invention to provide a simple and compact bell 1-travel device using a roller means formed by arranging small-diameter rollers in parallel, and to rationally solve the above-mentioned problems.

One example of the present invention will be specifically described below based on the drawings.

Figure 2 is a side view of a soy 1-be/l/1 sander according to the present invention which is properly pressurized. A reverse-phase frame is installed on the upper part of (2), and a row of idle rolls 4 and drive rolls 5 are mounted on the front and rear ends of the shipping frame 2, and an endless feed bell 1-6 is installed between these rolls. Stretch it. This feed belt 6 is rotationally driven in the direction of the arrow in the figure by a motor M connected to four drive rolls 5 via a speed change mechanism 7, and transports the four-inch workpiece in the same direction. Note that the reference number 8 is an operating handle associated with the elevation adjustment mechanism 3.

Next, each mechanism disposed on the negative side of the feed belt 6 will be explained. Each of these mechanisms is mounted on a column 9 erected on the side of the machine base 1, and this mounting is carried out using a frame consisting of a horizontal beam member fixed to the two-layer column 9. The frame 10' is installed in the width direction of the feed bell 1-6. The following roller means are disposed on the upper and lower sides of the base frame 10.

1. The roller means of I is composed of a front drive roller 12 supported on a bearing 1 and a rear guide roller 14 also supported on a bearing 13. A motor (not shown) is associated with the roller 12, and is caused to move the roller 11 once per cycle.

Next, the roller means of ``It111'' is constituted by front and rear small diameter rollers 17F1 and 17b which are arranged in parallel via support 44 and 15Kllllllll receivers 16) 1 and 161), and the small diameter rollers 1721,]7
b[ relates the belt tensioning means described later and the tilting device for running the belt on a track via the support frame 15.

The above upper and lower roller means are as follows: 1 frame 1
An endless sanding belt 18 is suspended so that the sanding belt 18 is surrounded by 0.
is rotated in the direction of the arrow Q in the figure by the drive roller 12.Furthermore, a tread pad device is installed in the running portion of the bell 1 between the drive roller 12 and the guide roller 14.
J] 9 (lift), and the pad device 19
The material is pressed in the 1-18 direction, and the wave-processed material being transported backward is subjected to a proper grinding process.

Next, the belt tension means and tilting means described above will be explained. The tensioning means for the unswitching bell 1 is taken upward, and fixes the pneumatic cylinder 20 to the j-frame 10, and connects its pinuton rod 20fL to a bearing 21 provided at the midpoint of the support frame 15. When the two-layer piston rod 20a is operated in the extending direction, the support frame 15 is raised and the sanding belt 18 is tensioned to apply appropriate tension to it.

1. The tilting means is constructed by associating a horizontal pneumatic cylinder 22 which is alternately operated and controlled by a solenoid valve (not shown) at the end of the support frame which is free to rotate in the horizontal direction by the bearing 21. 7a, 1 through the support frame 15 by the expansion and contraction of the piston rod 221L.
The axis of the sanding belt 7b is deflected back and forth repeatedly to cause the sanding belt 18 to perform a required trajectory.

Note that reference numerals 23 and 23 indicate stoppers that come into contact with the support frame 15 to regulate its deflection range.

One embodiment of the belt running device according to the present invention is as described above, and in rotatably suspending the endless leading belt 1-18, roller means for tensioning and running on the track is used. Since it is composed of a pair of small-diameter rollers 1711□ and 1711 arranged in parallel, the weight can be reduced and the required height can be significantly reduced. In addition, along with this, it is possible to design each part of the bearing, the support frame, and the tension pneumatic cylinder to be compact, and the lff1 component of the traveling device 1 can be made into IAI, making it lightweight and compact. It is possible.

In the above embodiment, the so-called head part that performs the grinding process faces downward and is of a pad suppression type, but it may be made to face in two directions, or it may be of a roller suppression type (contact roll type). , or a combination of both. In the first embodiment, both the tension means and the tilting means are associated with the upper roller means, but other roller means may be provided and the tension means and the tilting means may be associated with this. Therefore, the present invention can be applied to this type without exception.

As is clear from the description of the following embodiments, according to the present invention, the belt running device can be made extremely small and compact with a simple configuration that uses a pair of parallel small diameter rollers instead of the conventional large diameter roller. Therefore, the intended purpose can be achieved rationally.
