Description

[Detailed Description of the Invention] The present invention relates to a shirt conveyor that reciprocates with a constant stroke, and in particular, removes fallen raw materials that have fallen from the shirt conveyor body during conveyance and accumulated on the work floor. The present invention relates to a shirt conveyor that can automatically collect and process shirts while traveling.

Generally, when charging raw materials into an ore storage tank, such as a surge hopper in a sintering machine, in order to burn the raw materials evenly and uniformly, it is necessary to charge the raw materials evenly to avoid uneven accumulation, so the charging position must be adjusted. A shirt tank conveyor is used that reciprocates with a constant stroke in order to change the temperature appropriately.

However, in this case, a situation has arisen in which the raw material falls from the shirt conveyor body during conveyance and accumulates on the work floor.

The deposits from falling raw materials on the working floor interfere with the operation of the shirt conveyor itself and cause environmental deterioration.For this reason, the deposits on the working floor have been collected and treated. The reality is that the work requires a lot of effort and time.

The present invention has been developed in view of the above, and utilizes the reciprocating movement of the shirt conveyor body with a constant stroke to automatically scrape out deposits on the work floor only in one direction of raw material conveyance, making the collection process more efficient. In addition, the present invention aims to provide a shirt conveyor that can save labor, and one embodiment thereof will be described in detail below with reference to the attached drawings.

First, in FIGS. 1 and 2, 1 is the main body of the shirt torque conveyor that reciprocates with a constant stroke on a rail 4 laid on the working floor 3 above the surge hopper 2. Raw material a on cart 5
An endless conveyor belt 6 is stretched in order to charge the materials into the surge hopper 2.

Reference numeral 7 denotes a plurality of rotatable belts 7 installed perpendicularly to the running direction of the conveyor belt 6 at a position that does not interfere with the operation of the conveyor belt 6 at the lower end of the truck 5 and with equal gaps equal to or less than the stroke length. A support arm 13 having a plurality of scrapers 8 and cam rollers 9 at its lower end is attached to each of the pivots 7, as will be described later.

That is, as shown in FIGS. 3 and 4, the scraping plate 8 has its upper edge 10 fixedly held on the pivot shaft 7, and its lower edge 11 is arranged so as to face the work floor 3. 13 is located on both sides of the scraping plate 8, and
The upper end 12 is attached to both sides of the pivot shaft 7 at a predetermined angle in the backward movement direction of the bogie, and this support arm 13
The cam roller 9 is rotatably mounted on the lower end 14 of the cam roller 9.

Note that the scraping plate 8 and the support arm 13 held by the pivot shaft 7 are
At all times, the support arm 13 is maintained in a vertical position and the scraping plate 8 is maintained in a floating state.

15 are formed separately along the rail 4 on the upper surface of the work floor 3 in the sliding range of the cam rollers 9 on both sides, that is, in the forward and backward movement range that follows the constant stroke reciprocation of the shirt torque conveyor main body 1, as shown in FIG. The cam plates are arranged in a staggered manner and partially overlapped with each other, and the cam plates 1
5 has guide surfaces 16 and 17 formed at both ends thereof to facilitate the transfer of the cam roller 9 to the cam plate 15, and the length thereof is shorter than the distance between constant strokes of the shirt conveyor body 1. In addition, it is formed to be longer than the distance between the respective pivots 7.

Therefore, when the shirt conveyor main body 1 is traveling forward, as shown in FIG.
The shirt conveyor main body 1 advances forward by following the forward movement of the shirt conveyor main body 1 while giving a vertical state by a swinging motion using the fulcrum as a fulcrum.
Moreover, by being released from the cam plate 15 on the front guide surface 16, the vertical state caused by the swinging movement of the scraper plate 8 with the pivot shaft 7 as a fulcrum is released, and on the other hand, at the exit in FIG.
The cam roller 9 moves and slides from the front guide surface 16 onto the cam plate 15 and retreats while giving the scraper plate 8 a floating state by a swinging motion with the pivot shaft 7 as a fulcrum.
It is made so that it can be released from the cam plate 15 and returned to its original position.

The purpose of keeping the scraper 8 in a vertical state during forward travel is to bring the support arm 13 into contact with a stopper 18 provided on the cart 5 side of the shirt conveyor main body 1, as shown in FIGS. 3 and 4. Let it be done by.

Furthermore, numeral 19 in the figure is a baffle plate that prevents the raw material a from scattering when the raw material a is charged into the surge hopper 2.

The present invention is constructed as described above, and when the material a is conveyed by the shirttle conveyor main body 1, the deposits a' on the working floor 3 of the material falling from the conveyor belt 6 are collected by the shirttle conveyor main body 1. During forward travel during constant stroke reciprocating travel, the scraper plate 8 is used to sequentially move only in one direction in the conveyance direction to perform collection processing.Next, the operating procedure will be described in detail based on Fig. 4. .

That is, in the forward run of the shirt conveyor main body 1,
The scraping plate 8 and the cam roller 9 start from the starting point (2) shown by the dashed-dotted line as indicated by the solid line arrow A in the same figure, and during the transfer from the rear guide surface 17 of the cam roller 9 onto the cam plate 15 as shown by the dashed-dotted line II. Pivot 7 via support arm 13
The scraping plate 8 is held in a vertical state by the swinging motion using the support arm 13 as a fulcrum and the contact with the stopper 18, and the lower edge 11 of the scraping plate 8 is in sliding contact with the work floor 3, and the cam roller 9 is moved against the cam plate. While sliding on the shirt conveyor body 15, the scraper plate 8 follows the shirt conveyor body 1 and moves forward.

Therefore, the deposits a' on the work floor 3 are scraped in the raw material conveying direction by the vertical scraping plate 8, and moved to the scraping plate located immediately before.

Then, at the end of the constant stroke travel of the shirt torque conveyor main body 1, the cam roller 9 moves to the cam plate 15.
When the scraping plate 8 is released from its vertical state as shown by the solid line, its lower edge 11 is separated from the surface of the work floor 3.

Next, in the return run of the shirttle conveyor main body 1, the cam roller 9 is guided by the front guide surface 16 and transferred onto the cam plate 15 from the above-mentioned end III, as indicated by the dashed-dotted arrow in the figure, and the cam roller 9 is guided by the front guide surface 16 and transferred onto the cam plate 15, as shown in (3) Support arm 1
3, the scraper 8 is given a rocking motion about the pivot 7 as a fulcrum, and the lower edge 11 of the scraper 8 floats away from the surface of the work floor 3. In this floating state, the scraper 8 moves against the cam plate 15 of the cam roller 9. As it slides on the top, it follows the shirt conveyor main body 1,
Moreover, the worker leaves work and returns to his original position without moving the deposit a'.

Due to the correlation between the cam roller 9 and the cam plate 15, the work floor 3 is
The deposits a' on the surface are sequentially moved from the rear to the front by the scraper plate 8, that is, in one direction in the raw material conveyance direction, and finally the deposits are scraped out by the scraper plate at the front stage and dropped into the surge hopper 2.

In this way, according to the present invention, when the shirt conveyor main body reciprocates at a constant stroke, the scraper moves back and forth while being given a rocking motion to sequentially remove deposits on the work floor only in one direction of the raw material conveyance direction. Since the structure is moved from the rear to the front, the structure is simple, and the deposits can be automatically dropped into the surge hopper and collected, reducing the amount of time required for the conventional treatment. This is a useful idea that can reduce labor and time.
