Description

[Detailed explanation of the idea] (b) Industrial application fields Concerning a conveying device using an endless belt.

(B) Prior Art A belt conveyor is a device that circulates an endless annular belt between belt wheels at both ends, and transports goods by placing it on the belt. Therefore, as the conveyance distance becomes longer, the weight of the conveyed product and the weight of the belt itself increase, making it impossible to convey the belt over long distances.
Therefore, the applicant of the present invention first devised a belt conveyor for long distance conveyance according to Utility Model Publication No. 1983-780 as a feces removal device for livestock barns. The belt conveyor disclosed in Japanese Utility Model Publication No. 61-780 has a number of shafts fixed to the surface of the belt at right angles to the direction in which the belt travels, and wheels are attached to both ends of the shafts (on both sides of the belt). The present invention is a further improvement of this belt conveyor.

(c) Purpose of the invention The present invention is a modification of the belt conveyor disclosed in the above-mentioned Japanese Utility Model Publication No. 61-780, in which the running resistance of the belt is similarly reduced, reducing manufacturing costs. This is intended to increase efficiency.

(d) Structure of the idea A large number of shafts are fixed at regular intervals in the width direction of the belt on the inner surface of the endless belt, and a resin with a low coefficient of friction (oil-impregnated resin, polyamide resin, etc. A sled member made of fluorine resin, polyacetal, etc.) is attached, and at least the sled member on the conveying side (top side) belt is provided with a receiving material for the sled member,
The endless belt is driven by a wheel fixed thereto which is provided with transverse grooves that engage the sled shaft.

(E) Embodiment Figures 1, 2, and 3 show embodiments of the belt conveyor according to the present invention. FIG. 1 is a side cross-sectional view (A-A sectional view in FIG. 2), FIG. 2 is a plan view, and FIG. 3 is a front view taken along arrow B. Shafts 2 are fixed to the inner surface of an endless belt 1 at regular intervals in a direction across the belt. This is shown enlarged in FIG. 4 for one axis. The shaft 2 is made into a pipe, the lower part of which is tightly wrapped with a covering material 3 (such as a soft resin plate), and both upper ends of the shaft are joined to the belt 1.

The belt 1 engages with wheels at both ends of the conveyor (a drive wheel 4 and an idling wheel 5 provided oppositely to each other), and is pulled by the drive wheels 4 in the direction of the arrow. The belt 1 is engaged with the lateral grooves 6 which are fitted with the covering members 3 of the four shafts 2 at symmetrical positions on the outer periphery of the wheels 4 and 5. That is, the spacing between the shafts 2 mounted on the inner surface of the belt 1 is made the same as the pitch of the lateral grooves 6 of the wheels 4 and 5. Block sled members 7 having a low coefficient of friction, such as oil-impregnated resin, are fixed to both ends of the shaft 2 (both outside sides of the belt 1). A receiving member 8 (rail member) for receiving the sled member 7 of the upper side belt is provided.

9 is a motor for driving the drive wheel 4;
0 and 11 are the rotation axes 12 and 1 of the wheels 4 and 5, respectively.
This is a bracket that supports 3.

(f) Effects of the invention In this invention, when conveying goods by pulling a belt with wheels, a shaft is installed laterally on the back of the belt, and the drive wheel engages with the shaft to pull the belt. , there is no slippage between the belt and the wheels, and since the back side of the belt has horizontal shafts at regular intervals, and the horizontal shafts are supported by the support rails, it is possible to transport heavy objects without making the belt itself very strong. In addition, since the bearing slides on the receiving material through a sled member with a small coefficient of friction, it can generate a large traction force with a small amount of power. Since the resin block is attached to the shaft end,
The mechanism and structure thereof are extremely simple, and the belt conveyor is robust, has good traction efficiency, and is inexpensive.
