Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a belt conveyor used, for example, to transport bobbins in a spinning mill.

Prior Art and its Problems In the above-mentioned spinning factory, the production volume fluctuates, and the amount of bobbins conveyed by the conveyor within the factory also fluctuates accordingly.

By the way, conveyors are manufactured according to the planned amount of conveyance, so if there is a change in the amount of conveyance, the conveyor must be rebuilt each time, which causes an increase in equipment costs.

The purpose of this invention is to provide a belt conveyor that can easily accommodate variations in conveyance amount.

Means for Solving the Problems In the belt conveyor according to this invention, a plurality of endless belts are arranged in parallel at intervals, and conveyor frames are arranged on the upper and lower movement paths of the belts. is the same number of extruded belt guides as the number of belts placed under each belt, and a number of extruded intermediate belts that is one less than the number of belts placed between two adjacent belts. It is equipped with a conveyed object guide and two lateral conveyed object guides made of extruded material placed on the outside of the belt at both left and right ends, and upper and side opening notches are provided at the top of both left and right sides of the belt guide. are formed so that they are left and right symmetrical, and the two opposing notches of two adjacent belt guides are combined to form one upper opening fitting groove, and a side opening fitting groove is provided at the bottom of both left and right sides. are formed to be left-right symmetrical, and a downwardly protruding fitting protrusion is formed at the lower end of the intermediate conveyed object guide, which is fitted into the upper opening fitting groove, and the lower end of the side conveyed object guide is fitted with a fitting protrusion that protrudes downward. A side-protruding fitting protrusion is formed and is fitted into the side opening fitting groove.

Embodiment An embodiment of this invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the belt conveyor is for conveying bobbins 11 via a disc-shaped bobbin stand 12, in which the bobbins 11 placed on the bobbin stand 12 are lined up in a row. A plurality of parallel endless belts 21 are placed in parallel, and conveyor frames 2 are placed on the upper and lower movement paths of the belts 21, respectively.
2, and a transparent cover 2 having a downward U-shaped cross section and covering the upper and lower conveyor frames 22, respectively.
4, and a frame 25 that connects the upper and lower conveyor frames 22 and the transparent cover 24 at appropriate positions in the longitudinal direction.

Between the endless belts 21 there are gaps. Both ends of the endless belt 21 are wound around a driving pulley and a driven pulley (not shown), and both of these pulleys are mounted on a frame different from the upper and lower conveyor frames 22 described above.
Further, the upper moving path of the belt 21 is the return side, so that the empty bobbin 11 can be transferred to the belt 21.
The lower moving path is the feeding side, so that the bobbin 11 on which the thread is wound is conveyed.

The conveyor frame 22 has the same number of belt guides 30 as the number of belts 21 arranged below each belt 21 and the number of belt guides 30 that is the same as the number of belts 21 arranged between adjacent belts 21, minus one. It includes an intermediate conveyance article guide 31 and two side conveyance article guides 32 disposed on the outer sides of the two belts 21 at both left and right ends. Although not shown in the drawings, the belt guide 30 and the conveyed article guides 31 and 32 in each row are each formed of a plurality of members extending in a straight line in the length direction.

The belt guide 30 is formed of an extruded aluminum material so that its cross section is symmetrical. It consists of a pair of legs 42 attached to the member 26. The lower surface of the leg portion 42 has a downwardly opening inner enlarged groove 4.
3 is formed. A nut 44 is fitted into this internal enlarged groove 43, and a bolt 45 is screwed into the nut 44 through the horizontal member 26, thereby attaching the leg portion 42 to the horizontal member 26. Upper and side opening notches 46 are formed on both left and right edges of the belt sliding guide portion 41, and two opposing notches 46 of two adjacent belt guides 30 are formed.
are combined to form one upper opening fitting groove 47.

The intermediate conveyance article guide 41 is formed of a synthetic resin extruded material and is symmetrical with a substantially T-shaped cross section, and includes a vertical web 51 and a horizontal wing portion 52 provided at the upper end of the web. , Web51
A guide portion 53 with a downward U-shaped cross section provided at the lower end, and a fitting protrusion 54 with an upward U-shaped cross section provided at the lower end of the guide portion 53 so as to protrude downward. This fitting protrusion 54 consists of
is fitted into the upper opening fitting groove 47. The tip of the wing section 52 projects above the bobbin stand 12 placed on the belt 21, and the side surface of the guide section 53 guides the side surface of the bobbin stand 12.

The two side conveyance guides 42 are both made of synthetic resin and have an inverted L-shape in cross section, and have a vertical portion 61 and a horizontal portion 62. The directions are different. A laterally protruding fitting protrusion 63 is formed at the lower end of the vertical portion 61 and is fitted into the side opening fitting groove 48 . A guide portion 64 having a U-shaped cross section is formed in the middle of the height of the vertical portion 61, and a bobbin stand 1 placed on the belt 21 is attached to the side surface of the guide portion 64.
The second side is guided. Also,
The tip of the horizontal portion 62 protrudes above the bobbin stand 12.

Effects of the invention According to this invention, the number of belts and the number of belt guides and both conveyance object guides that make up the conveyor frame can be increased or decreased in response to fluctuations in the conveyance amount of the conveyor, thereby easily responding to fluctuations. can do.
