Abstract

PURPOSE:To obtain a chain conveyor by which a desired amount of material can be transferred upwards for supplying the material to the subsequent process from the supplying upper end, and by which transfer can be carried out with a minimum driving force by providing a recessed part in the longitudinal direction to slats at intervals of a prescribed number of slats. CONSTITUTION:A driving wheel 15 is driven by the drive of a motor 16 via a chain 17, thereby respective slats S fitted between the chains 17 on both sides are moved in the direction shown by the arrow. At that time the slat 35 positioned at the lower end and having a recessed part 35a receives materials M along the longitudinal direction in accordance with its size and the length of the recessed part 35a, for instance, 5 blocks of them, and they are transferred upwards. In the flush slats S having no ordinary recessed part 35a between these slats 35 and 35, since the inclination of the conveyor 14 is large, the materials slip, and only the materials M housed inside the recessed part 35a are transferred upwards.

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to chain conveyors.

0002

[Prior Art and its Problems] Various types of chain conveyors are known, such as a slat conveyor on which wooden or steel slats are attached to two chains, and conveyed objects are placed on the slats. There are apron conveyors that have polymerized flat plates to prevent the transported material from spilling. These are suitable for transporting items horizontally, but when moved upwards on an incline, some items can be transported upwards, while others, or depending on the angle of inclination, can be moved at their lower end. In some cases, the object may slip and be unable to be transported upward. In order to cope with this problem, it is conceivable to use a bread conveyor 1 in which each apron is shaped like a dish, as shown in FIG. 6, for example. With such a chain conveyor, it is possible to reliably transport a small amount of goods, such as certain types of seafood, upwardly into each apron 2 at the lower end of the chain conveyor. However, since all the seafood, such as scallops, that have entered this apron 2 are transported upward, and since these aprons 2 all have the same shape and are connected, the scallops fed to the lower end of the apron 2 are transported upward. Depending on the amount stored, it may become overloaded, and even if it is transported upward in this state, it may overflow, or the driving force of this chain conveyor must be extremely large.

0003

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems, and is capable of transporting a desired amount upward and supplying it to the next process from this supply end, and by reducing the driving force of this chain conveyor. The purpose of the present invention is to provide a chain conveyor that can be made as small as possible for transportation.

0004

[Means for solving the problem] The above object is to provide a chain conveyor in which a band plate is connected to two chains and a recess is provided in the longitudinal direction for each predetermined number of chains. This is achieved by a chain conveyor, which is characterized by:

[0005]

[Operation] When a chain conveyor is installed with an ascending angle of inclination and goods, such as scallops, are stored at the lower end and transported upward one by one, two strips of chain are connected with strips. However, these have recesses in the longitudinal direction for each predetermined number of sheets. Therefore, on the strips between these recesses, it may be difficult to slip and transport upwards in the same way as with conventional slat conveyors or apron conveyors; The scallops stored in the scallops can be efficiently scooped up and transported upwards, and since the strips with these recesses are provided for each predetermined number, this predetermined number can be adjusted appropriately. As a result, the amount of products fed from the upper end of the chain conveyor, such as scallops, can be adjusted to a desired value, and the driving force corresponding to this can be set to a minimum value.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a chain conveyor according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a scallop feeding apparatus according to an embodiment of the present invention. In FIG.
Although not shown in the figure, it is attached to the inside of the frame 13 by an appropriate attachment means, and a partition plate 12 is provided at the rear of this frame 13, and by this and side walls provided on both sides of the frame 13, although not shown in the figure. A storage section V is formed, in which a large amount of scallops M are stored according to this embodiment. This is stored at the lower end of the chain conveyor 14. The details of the chain conveyor 14 are shown in FIGS. 2 and 3, and slats are connected between the drive wheel 15 and the driven wheel 18 and attached to the chains on both sides. The drive wheel 15 is driven by the drive force of the pulley of the electric motor 16 through the chain 17.
Driven through. It is assumed that this electric motor 16 can be adjusted according to the required amount of the next process. The scallops M discharged from the chain conveyor 14 are guided to a guide chute 19, and from there are supplied to a discharge chain conveyor 21 provided with a V-shaped transfer path. The chain conveyor 21 also has a V cross section between the drive wheel 22 and the driven wheel 23.
The letter-shaped elements are connected and attached between two chains, and the drive wheel 22 is driven by a motor 24 via a chain 25.

Next, details of the chain conveyor 14 according to the present invention will be explained with reference to FIGS. 2 and 3. The present chain conveyor 14 also includes a pair of chains 31, which are composed of a chain element 34 for holding slats and a connecting chain element 33 that connects these chain elements 34, as is known in the art. 34, as shown in FIG. 3, slats S serving as strip plates are connected to the chains 31 on both sides in the upper running part and the lower running part without gaps, and according to this embodiment, Groove-shaped recesses 35a extending in the longitudinal direction are formed in the slats 35 at intervals of two slats S.
is formed, and the slat S between them is just a flat plate like the conventional slat, and its upper surface is the same as the slat 3.
It is flush with the upper surface of both ends where the recess 35a of No. 5 is not provided.

Next, details of the guide chute 19, which is connected to the discharge end of the chain conveyor 14 and inclined downward, will be described in detail with reference to FIGS. 4 and 5. This consists of a bottom wall surface 40 as a chute surface, and partition plates 41, 42, 43, 44, 45 attached thereto at predetermined angles to define four runway surfaces as shown in the figure.
Further, on the side surfaces of these partition plates 42, 43, 44, 45, guide walls 46, 47, 48, 49 are provided, extending from near the upper end to the lower end in order from the right side in FIG.
is provided, which allows the scallop transfer chute A
, B, C, and D road surfaces are formed. In addition, the outlets a, b, c, and d of these chutes are located at the bottom of the valley at the supply end of the chain conveyor 21 for each element 50 having a V-shaped cross section and forming a transfer path for the following chain conveyor 21. Outlets a, b, c, and d are arranged to face 50a. Since the chain conveyor 21 formed by connecting a large number of these V-shaped elements 50 is well known, further explanation will be omitted, but these elements 5
In this embodiment, 0 has dimensions such that one scallop is transported upward in one row and one layer.

The scallop feeding device according to the embodiment of the present invention is constructed as described above, and its operation will be explained next.

The drive wheel 15 is driven through the chain 17 by the drive of the motor 16, and each slat S attached between the chains 31 on both sides moves in the direction shown by the arrow, and at this time, the slat S is located at the lower end. , and recess 3
The slat 35 with 5a has a scallop M in its recess 35a.
, depending on the size and the length of the recess 35a, for example, 5
The pieces are received along their length and transported upward. Note that the normal recess 35a between these slats 35, 35
In the case of a flush slat S without a slat S, the angle of inclination of this chain conveyor 14 is large, so it slips and the recess 35a
Only the scallops M housed inside are transferred upward. These are supplied from the discharge end of the chain conveyor to the chain conveyor 21 for discharge through a guide chute 19. In this embodiment, the guide chute 19 is arranged in four rows as shown in FIGS. 4 and 5. However, although it slides along each of these transfer paths A, B, C, and D, it is not aligned with the chain conveyor 14 on the upstream side, but is provided inclined to one side by a predetermined distance, In addition, the outlets a, b, c, and d of each chute transfer path A, B, C, and D are in a positional relationship as shown in FIG. 4 with respect to the V-shaped element 50 located at the lower end of the chain conveyor 21. , one scallop M is discharged from each outlet a, b, c, and d, and heads toward the valley bottom 50a at a relatively low speed at the lower end of the chain conveyor 21.

As described above, the upstream ends of each of the transfer paths A, B, C, and D are arranged in alignment with the chain conveyor 14 disposed upstream. A,
The discharge ends a, b, c, and d of B, C, and D are offset from the upstream end, so that the chain conveyor 21 connected thereto and the upstream chain conveyor 14 are aligned. Although this is not the case, with the configuration of the guide chute 19, it is possible to transfer the pieces one by one in a single layer and in a single row through a transfer path made up of V-shaped elements 50 in each row of the chain conveyor 21. In other words, since the discharge ends a, b, c, and d are arranged offset to one side with respect to the upstream end of the guide chute 19, the transfer paths A, B, and C
, D can be made smaller inclination angle with respect to the horizontal line,
Therefore, even if the difference in level between chain conveyor 14 and chain conveyor 21 is large, these chain conveyors 14 and 2
Compared to the case where the scallops are lined up and connected by a guide chute, the angle of inclination for sliding can be made smaller. . - Can be transported upwards in a single row. In other words, when the upstream chain conveyor 21 is arranged at a large inclination angle as in this embodiment, and the downstream chain conveyor 21 is also arranged at a large inclination angle, scallops are transferred from the discharge end of the former to the supply end of the latter. When supplying the guide chute 19, the inclination angle of the guide chute 19 can be reduced by increasing the length of the entire device in the horizontal direction, but the installation area of such a device generally cannot be increased. Normally, in order to reduce this, the angle of inclination of the chain conveyors 14 and 21 must be increased as shown in the figure. This embodiment is particularly effective when transporting scallops.

The embodiment of the present invention is configured as described above,
And it works, and it has the following effects.

[0014] That is, in the chain conveyor 14, since every second slat 35 is provided with a recess 35a, the scallops M are scooped up in an amount matching the requirements of the next process and transferred to the upstream side. Moreover, on the slats which do not have the recesses 35a between them, the scallops M almost never slip and are not transported upward. Therefore, the driving force of this chain conveyor 14 can be minimized.

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the embodiments described above, the present invention was applied to a scallop feeding device, and the guide chute 19 and the chain conveyor 21 were provided, but these were omitted and other components were used according to the requirements of the various feeding devices. Other evacuation devices may also be provided.

Further, in the above embodiment, the slats 35 are provided every second slat, but this predetermined number may be changed depending on the ability required by the next process.

[0018]

As described above, according to the chain conveyor of the present invention, the goods stored at the lower end of the chain conveyor, such as scallops, can be efficiently transported upward, and the The force can be set to a minimum.
