Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> The present invention relates to a housing block for attaching a conveyor base material that is particularly easy to assemble, a belt conveyor using the housing block, and accessories thereof.

<<Prior Art>> Conventionally, in a relatively small belt conveyor for conveying mechanical parts, etc., the housings on the drive shaft side and the driven shaft side, which are provided at both ends of the conveyor base material in the feeding direction, have housings as shown in FIG. 7, for example. installed on.

That is, the conveyor base material 1 is formed of a hollow elongated box such as an aluminum profile, and a housing made of a rectangular plate made of plastic or the like is attached to the left-right wall surfaces 1c and ld at both ends of the conveyor base material 1. The housing 4 is formed by the pair of left and right housing blocks 2.2, which are attached to each other through bolts 3 and are attached so as to face each other.

Of course, in this case, the pulley 5 is rotatably inserted and supported in the housing 4 between the inner surfaces 2a, 2a of the housing blocks 2, 2, and one of the housings 4 is equipped with a motor (not shown). - is provided as a housing on the drive shaft side, and the other housing is configured as a housing on the driven shaft side.

Then, an endless belt 6 is stretched around the upper and lower surfaces 1a, lb of the conveyor base material 1 and the pulleys 5, 5 of the drive shaft side and driven shaft side housings, and this endless belt 6 is conveyed as the motor is driven. Ru.

In the conventional belt conveyor of this type, the housing 4 is generally formed as follows (see FIG. 7(b)).

First, one end side of the housing block 2 made of a rectangular plate is attached to a predetermined portion of the end side wall surface IC and 1d of the conveyor base material 1.

Then, the bolt 3 is inserted into the mounting hole 7 formed in the housing block 2, and also inserted into the elongated hole 8 formed in the conveyor base material 1.
The housing block 2 is fixed to the conveyor base material 1 by screwing into a nut 9 disposed inside the conveyor base material 1.

<<Problems to be Solved by the Invention>> Incidentally, in this type of belt conveyor, a pair of left and right housing blocks 2.2 must be precisely positioned and placed opposite each other at the ends of the conveyor base material 1.

That is, if the pair of left and right housing blocks 2, 2 are not accurately positioned and fixed, the pulley 5 over which the endless belt 6 is stretched cannot be installed so as to be perpendicular to the feeding direction of the endless belt 6. Therefore, there is a problem in that the endless belt 6 meanderes during driving, making it impossible to smoothly rotate and convey the belt.

However, as described above, the conventional housing block 2 is simply formed into a plate shape and is attached and fixed to the flat side wall surface IC or 1d of the conveyor base material 1, so the pulley 5 is endless. The housing block 2 is placed perpendicularly to the feeding direction of the belt 6.
It is extremely difficult to accurately position and fix the assembly, and there is a problem in that assembly workability is poor.

Furthermore, since the ends of the conveyor base material 1 are formed at right angles, when the endless belt 6 is conveyed from the conveyor base material 1 to the pulley 5 so as to be wound around the conveyor base material 1, the conveyor base material 1
Since the belt 6 is rubbed against the corner of the end of the belt 6, the contact pressure becomes large, causing problems such as damage to the belt 6 over time.

Furthermore, this type of conveyor is designed to prevent mechanical parts and the like from falling off during conveyance.
In some cases, guide bars, guide plates, etc. are installed upright along 1d, but in the past, these types of accessories were prepared independently by the user, and these accessories were fixedly attached. The height cannot be adjusted, and therefore, when conveying mechanical parts of different heights, there are problems such as the mechanical parts falling off the endless belt 6 while being conveyed.

This invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a housing for a driving shaft and a driven wheel that can be easily assembled with good workability and precision. It is an object of the present invention to provide a housing block for attaching a conveyor base material, which has effects such as being able to convey an endless belt smoothly.
