Abstract

PURPOSE: To obviate the necessity for frequently cleaning a bread while improving transport efficiency of a bread conveyer device, by using a flexible sheet member having longer durability, since the deformation is caused by an external force inevitably applied by a mechanical constitution and mechanical motion. CONSTITUTION: In a bread conveyer device 40 driving a chain of fixing a bread 51 for mounting a transport object in each chain link by rotating each sprocket to transport the transport object in the bread 51, the device comprises a dam plate 60 isolating inside the bread 51 from inside the adjacent bread 51 to be vertically provided in one end of the bread 51 and an inner side sheet member 64 provided to be folded inside the bread 51 to fix both end parts to a position of the dam plate 60 distant from the chain link and to have flexibility. Thus, by deforming the inner side sheet 64 moved to be pulled so as to relatively isolate its both end parts, a contact position between the inner side sheet member 64 and the transport object is changed, to separate the transport object.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bread conveyor device, and more particularly to a bread conveyor device for improving the transportation efficiency and maintainability of the package.

[0002]

2. Description of the Related Art As a conventional bread conveyor device, for example, there is one shown in FIG. That is, in the figure, box-shaped pans 13 are fixed to each of the chain links 11 constituting the chain so as to be adjacent to each other in the length direction, and the chain is rotated by the rotation of a sprocket (not shown) that drives the chain. Link 11 is the direction of travel (arrow direction)
To move the cargo 15 loaded in the pan 13.
As shown in the figure, when the bread conveyer device transports the packages 15 while rising diagonally upward, a skid board 17 is erected at one end of each pan 13 so that the packages 15 can be stacked in the bread 13 as much as possible. ing.

[0003]

However, in such a conventional bread conveyor device, when transporting a transportation material 15 having a high adhesive property, such as wet earth and sand, peat, asphalt, etc., the bottom of the bread 13 is to be transported. Package 1 in the corner
Since 5 gradually attaches and grows, the transport amount of the transported material 15 is gradually reduced and transport efficiency is lowered, and in order to prevent this, the inside of the pan 13 must be cleaned one by one. It has a problem of poor sex.

In order to solve such a problem, for example, there is a bucket conveyor device as shown in FIGS. 13 and 14, though not a pan conveyor device. In FIG.
Reference numeral 20 is a bucket, 22 is a chain link, 24 is a sprocket, 26 is a motor for rotationally driving the sprocket 24 via a roller chain 28, and 30 is a bucket 20.
It is a discharge part that discharges the packages dropped from the.

In such a bucket conveyor device, when the motor 26 moves the chain link 22 through the sprocket 24 in the direction of the arrow, the bucket 20 fixed to the chain link 22 moves together, and the sprocket 2 moves.
When it comes to the right semi-circle side of 4, the transported articles piled up to that point are dropped and discharged to the discharge section 30 side.

As shown in FIG. 14, some buckets 20 of such a bucket conveyor device have a flexible expansion / contraction member 32 which is expandable / contractible inside thereof.
When the package is loaded inside the bucket 20, the expansion / contraction member 32 is in a crushed and contracted state as shown by the chain double-dashed line, but when the bucket 20 reaches the discharge position, the package is discharged and lightly. Therefore, the expansion / contraction member 32 is expanded as shown by the solid line by the self-repulsive force due to the elasticity, and the rest of the transported object can be discharged completely.

However, the expansion / contraction member 32 of the bucket 20 of such a bucket conveyor device can be expanded / contracted as intended due to its elasticity while it is new, and its function can be sufficiently exerted, but depending on the time of use or its physical properties, the expansion / contraction member may be gradually expanded. There is a problem that it deteriorates and loses elasticity, and eventually it loses its self-repulsive force and cannot fully exert its function. For this reason, the durability of the expansion / contraction member 32 becomes limited, and it may be necessary to replace it. This is because the expansion / contraction member 32 of the bucket 20 can exhibit its function only by its elasticity and self-repulsive force.

In view of the above problems, the present invention uses a flexible sheet member having a longer durability because it is deformed by an external force inevitably applied due to its mechanical structure and mechanical movement. It is an object of the present invention to provide a pan conveyor device that improves the transport efficiency of the pan conveyor device and improves the maintainability that does not require frequent cleaning of bread.

[0009]

In order to solve the above-mentioned problems, a bread conveyor device according to the present invention is designed to drive a chain, in which a pan for holding a transported object is fixed for each chain link, by driving a sprocket to rotate the inside of the pan. In a bread conveyer device for transporting the transported article, a baffle plate that is erected at one end of the bread that separates the inside of the bread from the inside of the adjacent bread, and both ends that are provided by bending inside the bread are A flexible inner sheet member fixed at a position away from the chain link of the baffle plate is provided, and a partial hole is formed in the bottom of the bread, or a bottom of the bread is formed. The structure is completely open.

[0010]

According to the bread conveyor device having such a configuration,
The package is transported on the flexible inner sheet member in the pan. And the pitch interval between the bout board of the other bread standing upright at one end of the bread is the link connecting pin that connects each chain link of the chain when each bread moves in a straight line. Although the pitch interval of each link connecting pin of the chain does not change when the chain is wound around the sprocket and rotates, the claw plate is connected to the link connecting part in the radial direction of the sprocket. Since it is located outside the radius of the pin, the adjacent baffles are separated from each other so as to open in a fan shape.

Since both ends of the flexible inner sheet member are fixed to the claw plate at positions away from the chain link, the fixing positions are also separated from each other. For this reason, in the sprocket part for discharging the transported object, the inner sheet member is moved and deformed by being pulled so that both ends thereof are relatively separated, and the contact position between the inner surface of the pan and the inner sheet member, and The contact position between the inner sheet member and the transported article changes, and the space between the inner sheet member and the transported article separates.

For this reason, the transported article is easily dropped from the inner sheet member in the pan, the transportation efficiency can be improved by preventing the transported article from adhering to the inner sheet member, and the transported article attached from the inner sheet member can be prevented. There is no need for frequent cleaning to remove. Further, since the inner sheet member moves and deforms due to the external force inevitably applied by its mechanical structure and mechanical movement, its durability can be remarkably increased by being able to function without self-repulsion force. There is no need to frequently change the inner sheet member.

Further, by forming a partial hole in the bottom of the bread, it is possible to prevent the bottom of the bread and the inner sheet member from being hermetically sealed to facilitate the movement and deformation of the inner sheet member. it can. Further, by opening the bottom of the bread entirely, the inside sheet member and the inside of the bread can be easily cleaned, and the weight of the bread can be reduced, in addition to the above effects.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 11 are views for explaining an embodiment of a bread conveyor device according to the present invention. First, the configuration of this embodiment will be described.

By rotating the sprocket 44,
The pan 51 also rotates in the direction of the arrow around the sprocket 44 integrally with the chain links of the chains 48 and 49.
For this reason, the mouth of the pan 51 is gradually downward, and the transported articles that have been stacked are gradually spilled due to gravity and finally fall into the belt conveyor 46 (see FIG. 1).

FIG. 4 is a plan view (a) and a side view (b) showing the pan 51. The pan 51 has a pair of pan side plates 53 and 54 having a shape as shown in FIG. 4B, and the arc-shaped portion 5 is located on the lower right side of the pair of pan side plates 53 and 54 in FIG. 4B.
A pan front plate 57 having 7a is bridged between the pan side plates 53 and 54 and fixed by welding or the like so as to connect the two. On the lower left side of the pan side plates 53 and 54 in FIG. 4B, a pan rear plate 58 similarly having an arc-shaped portion 58a is hung between the pan side plates 53 and 54 and fixed so as to also connect the two. There is. Therefore, the bottom of the pan 51 is entirely opened, and the bottom is completely removed.

A baffle plate 60 is erected on the top of the arc-shaped portion 57a of the pan front plate 57 by welding or the like.
0 is also provided between the bread side plates 53 and 54 along the length direction of the bread front plate 57. Pan side plates 53 and 54 are 2 in the middle
It is formed by bending in opposite directions.
As shown in (a), the width of the left end portion of the pan 51 in the drawing is larger than the width of the right end portion in the drawing. Pan side plates 53, 54
There are two holes 63 in the center of the hole, through which bolts for connecting the pan 51 to the chain links of the chains 48, 49 pass.

FIG. 6 is a diagram showing the internal configuration of the pan 51 and the positional relationship between them. The breads 51 are adjacent to each other through an overlapping portion Q where the larger width end and the smaller width end overlap each other, and at this time, the arc-shaped portion 57a of the bread front plate 57 is on the upper side of the bread rear plate 58. It overlaps with the arcuate portion 58a. Seki board 6
0 stands at the boundary between the adjacent breads 51 to isolate the insides of the breads 51 from each other, and rises high in order to increase the transport amount of the transported object C when the breads 51 rise in the inclination direction as shown in FIG. It is set up.

In FIG. 6, an inside sheet member 64 as shown in FIG. 8 is provided inside the bread 51 along the inner surfaces of the bread front plate 57 and the bread back plate 58 by bending. Both ends of the slab are located above the siding plate 60 in the figure.
It is held down by a holding plate 65 as shown in FIG. For this reason, the central portion of the inner sheet member 64 closes the bottom of the pan 51, and the packages are loaded thereon.

A material having flexibility is used for the inner sheet member 64. For example, rubber, synthetic rubber, a cored rubber belt used in a belt conveyor, a mixture of cloth and rubber, rubber-like plastic, Alternatively, a thin stainless plate or the like is used. These materials are more easily deformable and bendable than the iron plates constituting the pan side plates 53, 54, the pan front plate 57, the pan rear plate 58, and the baffle plate 60 of the bread 51, and have excellent adhesiveness. It has the property that it does not easily adhere to transported materials.

FIG. 10 is an enlarged view showing the S section in FIG. 2 in detail. The chain 49 has an inner chain link 49a having a small gap width and an outer chain link 49b having a large gap width. The inner chain link 49a and the outer chain link 49b are overlapped at their end portions to form the link connecting pin 50. (See FIG. 3). The inner chain links 49a and the outer chain links 49b are arranged alternately in the length direction. A chain roller 49c is provided in the gap between the ends of the inner chain link 49a. The chain roller 49c engages with the groove portion 44a of the sprocket 44 (see FIG. 3) to rotate, so that the length of the chain 49 increases. Then, the pan conveyor device 40 exerts a transportation function.

The inner chain link 49a on the pan 51 side of the chain 49 is fixed to the pan side plate 54 of the pan 51 by a bolt via a spacer plate 68. Chain 4
The outer chain link 49b of the pan 51 on the side of the pan 51 is attached to the pan side plate 54 of the pan 51 by a bolt through the spacer plate 69.

The pan 51 shown in FIG. 4 is a pan side plate 53, 54.
A spacer plate 68 is provided at the center of the chain 51, so that the pan 51 shown in FIG. 4 is fixed between the inner chain link 49a of the chain 49 and the inner chain link of the chain 48. On the other hand, the pan 51 shown in FIG. 5 is provided with a spacer plate 69 on the pan front plate 57 side of the pan side plates 53 and 54, and therefore the pan 51 shown in FIG. It is fixed between 48 outer chain links.

According to the bread conveyer device 40 having such a configuration, the articles to be transported are stacked and transported on the flexible inner sheet member 64 in the bread 51. Then, as shown in FIG. 6, the skid plate 6 erected at one end of each pan 51.
The pitch interval between 0 is the same as the pitch interval Po of each link connecting pin 50 of the chain when the pans 51 move in a straight line. When the chain winds around the sprocket and rotates, the pitch spacing of the link connecting pins 50 of the chain does not change, but the baffle plate 60 is located outside the link connecting pins 50 in the radial direction of the sprocket. Therefore, the adjacent baffles 60 are separated from each other so as to open like a fan.

The inner sheet member 64 having flexibility
Both ends of the claw plate 6 should be away from the chain link.
Since it is fixed to 0, the fixed positions are also separated from each other, and the interval Px is larger than the pitch interval Po. Therefore, in the sprocket part for discharging the transported object, the inner sheet member 64 is moved and deformed by being pulled so that both ends thereof are relatively separated, and the contact position between the inner side surface of the pan 51 and the inner sheet member 64. , And the contact position between the inner sheet member 64 and the transported object changes, and the inner sheet member 64 and the transported object are separated from each other.

That is, when the pan 51 is moving in the linear direction, as shown in FIG.
1 is stacked on the inner sheet member 64, while the pan 51 moves in the circumferential direction around the sprocket 44, as shown in FIG. Inner sheet member 6 along with movement and deformation of 64
Even if the transported material C is peeled off from the No. 4 and has an adhesive property, the transported material C easily falls in such a state.

Further, as the material forming the inner sheet member 64, a material such as rubber to which the transported material C is less likely to adhere is used as compared with the iron plate as described above, so that the transported material C can be more easily peeled and dropped. be able to.

As described above, the transported material C is easily dropped from the inner sheet member 64 in the pan 51, and the transported material C can be prevented from adhering to the inner sheet member 64, thereby improving the transportation efficiency of the pan conveyor device 40. In addition, it is not necessary to perform frequent cleaning for removing the adhered goods C from the inner sheet member 64. Also, the inner sheet member 6
Since 4 moves and deforms due to the external force inevitably applied due to its mechanical structure and mechanical movement, its durability can be remarkably increased because it can function even without self-repulsive force. There is no need to replace it frequently.

Further, since the bottom of the pan 51 is completely opened, it is possible to prevent the bottom of the pan 51 and the inner sheet member 64 from being in a hermetically sealed state and to easily move and deform the inner sheet member 64. The inner sheet member 64 and the inside of the pan 51 can be easily cleaned, and the weight of the pan 51 can be reduced.

In the above embodiment, the case where the bottom of the pan 51 is completely opened has been described.
The pan 51 may be provided with a bottom and a hole may be partially formed therein, and in that case, the basic effect is not different from that of the above embodiment.

In the above embodiment, the sprocket 4 is used.
Although the number of teeth of 4 has eight teeth, the number of sprockets 44 may be at least more than eight. The smaller the number of teeth of the sprocket 44, the larger the movement amount and the deformation amount of the inner sheet member 64, so that the object of the present invention can be achieved more effectively.

Further, in the above embodiment, the case where the transported article C discharged from the pan 51 is discharged onto the belt conveyor 46 has been described.
The transported article C may be discharged to a place in any state such as another transportation means such as a chute or a hopper.

Further, in the above embodiment, various connecting portions,
Although the case where the fixing portion is connected and fixed using the bolt has been described, it goes without saying that a plate screw, a rivet, or any other means or device may be used in addition to the bolt.

[0038]

As described above, according to the bread conveyer device of the present invention, the transported article is easily dropped from the inner sheet member in the pan, and the transported article can be prevented from adhering to the inner sheet member. As a result, it is possible to improve the transport efficiency, and it is not necessary to frequently perform cleaning for removing the transported material attached from the inner sheet member, and thus it is possible to improve the maintainability.

Further, since the inner sheet member moves and deforms due to the external force inevitably applied by its mechanical structure and mechanical movement, the inner sheet member can function without self-repulsive force so that its durability is remarkably increased. This eliminates the need for frequent replacement of the inner sheet member.

Further, in the above-described embodiment, since the material for forming the inner sheet member 64 is a material such as rubber which is less likely to adhere to the cargo as compared with the iron plate as described above, peeling or dropping of the cargo is further prevented. Can be easy.

Further, in the above-mentioned embodiment, since the bottom of the pan 51 is completely opened, it is prevented that the bottom of the pan 51 and the inner sheet member 64 are sealed, and the inner sheet member 64 is moved. The deformation can be facilitated, the inside sheet member 64 and the inside of the pan 51 can be easily cleaned, and the weight of the pan 51 can be reduced.

Further, in the above embodiment, as shown in FIG. 6, the front end side of the pan 51 in the moving direction is narrower in width than the rear end side and overlaps at the overlapping portion Q, and the bread front plate 57 of the pan 51 has an arc shape. The portion 57a is the arcuate portion 5 of the pan back plate 58.
Since the articles C in the bread 51 are discharged from the bread 51 onto the belt conveyor 46, the articles C enter the overlapping portions and spill because they overlap each other. Can be prevented.

Further, in the above-described embodiment, in order to clean the transported article C attached to the pan 51, it is not necessary to remove the entire pan 51, but it is possible to easily perform it by only removing the inner sheet member 64. Maintenance work is significantly easier.

Further, even when a bottom plate is provided instead of opening the bottom of the pan 51 and holes are partially formed in the bottom plate, it is possible to prevent the inner sheet member 64 and the bottom plate from being hermetically sealed. The movement and deformation of the inner sheet member 64 can be facilitated. In this case, the structural strength of the bread 51 can be improved, and the present invention can be easily applied by modifying the conventionally used bread.
