[Structure] A horizontal bar member 21, two vertical members 22 provided vertically on both sides of a lower surface middle portion of the bar member, and an upper half circumference of a belt that is rolled into a pipe shape is retained between the vertical members. A plurality of upper shape-retaining rollers 23 supported, a bracket 28 having an end attached to the lower end of the vertical member, and a plurality of lower shape-retaining members supported to retain the lower half of the pipe-shaped belt on the upper side of the bracket. Both ends of the bar material are attached to the frame of the existing belt conveyor, which is composed of the rollers 23 ', and the return side belt is rolled.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a belt support frame for rolling a return side belt of an existing belt conveyor into a pipe shape to prevent falling powder.

[0002]

[Prior art]

 As shown in FIG. 3 and FIG. 4, the carrier side and return side belts of the conventional belt conveyor are supported by the rollers 3 for supporting the lower surface of the carrier side belt on the horizontal members 2 on both sides forming the conveyor frame 1. Both ends of the carrier side frame 4 having the above are fixed from the bolt and the nut through the tightening tool.

The carrier-side frame 4 is composed of a horizontal bar member 5 and a stand 6 standing upright from the upper surface of the bar member 5 and supporting the spindles of the rollers 3 on both sides of the center.

The belt on the return side has brackets 8 at both ends of the roller 7 fixed to the lower surface of the horizontal member 2 via fasteners, and the roller 7 supports the lower surface of the belt.

It should be noted that the horizontal member 2 is provided with leg members 9 at predetermined intervals in the front and rear.

[0006]

[Problems to be solved by the device]

 According to the belt conveyor as described above, the powder adhering to the belt falls in a long section on the return side of the belt from the head side to the tail side, so that a great deal of labor is required to process the fallen objects.

Therefore, by rolling the belt on the return side into a pipe shape, it is possible to prevent falling of powder in a long section on the return side.

However, in order to use the existing belt conveyor, the rollers supporting the return side belt are removed together with the brackets, and then a large number of rollers are supported on the circumference of the carrier side frame for rolling the belt into a pipe shape. I will install the frame.

In this case, since the carrier-side frame remains on the conveyor frame, the working space is small and smooth mounting cannot be performed.

Further, since the insertion holes for the fasteners are formed in the bar material of the carrier-side frame, there is a problem in that it is troublesome and the operation of the conveyor must be stopped for a long time.

Therefore, the present invention provides a belt bearing frame that facilitates replacement workability.

[0012]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention proposes a horizontal bar member having both ends attached to both sides of an existing belt conveyor frame by an appropriate method, and two downwardly projecting members on both sides of the middle portion of the lower surface of the bar member. Book vertical member, a plurality of upper shape-maintaining rollers that support the upper half of the belt to be rolled into a pipe shape between the vertical members, and both ends of the vertical members at the lower ends of the vertical members by appropriate means. A belt support frame for a belt conveyor is used that consists of a bracket that can be freely attached and a plurality of lower shape-maintaining rollers that support the shape of the lower half of the belt that is rolled into a pipe on the upper side of the bracket.

[0013]

[Action]

 When rolling the return belt of the existing belt conveyor, first remove the bracket with the supporting roller of the return belt from the horizontal member of the conveyor frame.

Next, after fixing both ends of the bar material to both horizontal members of the conveyor frame, both ends of the bracket are fixed to the lower ends of both horizontal members, and the upper shape-retaining roller and the lower shape-retaining roller are used to return side. Keep the shape of the belt rolled into a pipe.

[0015]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, reference numeral 21 denotes a horizontal bar member, and two vertical members 22 projecting downward are provided at both ends of the lower surface of the bar member 21.

Inside the both vertical members 22, a plurality of upper shape-retaining rollers 23 that retain the shape of the upper half of the belt a that is rolled into a pipe shape are supported.

The shape-retaining rollers 23 described above are arranged in a set of three and are supported by a stand 24 provided on the bar member 21 and the vertical member 22.

The bar member 21 is used when rolling the return-side belt A of the existing belt conveyor A into a pipe shape. By removing the bracket 8 from the horizontal member 2 of the conveyor frame 1 shown in FIG. After removing the roller 7, both ends of the bar member 21 are fixed to the horizontal members 2 on both sides (the bar members 21 are sequentially attached at a predetermined interval in front and rear).

As shown in FIG. 1, the fixing method described above is performed between the holding member 25 and the bar member 21 which are arranged parallel to the lower surface of both ends of the bar member 21 and whose ends are fixed to the bar member 21. Although the upper side of the parallel portion of the horizontal member 2 made of the channel member is interposed and the bolt 26 is clamped by being screwed in, a fastener made of a bolt and a nut may be used.

After the bar member 21 is attached to the conveyor frame 1, both ends of the bracket 28 are fixed to the lower ends of both vertical members 22 with the fasteners 27 including bolts and nuts.

On the upper side of the bracket 28, the lower shape-retaining roller 23 ′ is supported via the stand 24 so as to form a set of three pieces. To be done.

If the belt a rolled into a pipe shape is twisted during operation, the fastening tool may be loosened and the end of the bar member 21 may be moved in the traveling direction of the belt a.

[0024]

【effect】

 Since the belt support frame according to the present invention is configured as described above, the return side belt of the existing belt conveyor can be rolled into a pipe shape very easily by using this frame.
