Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) The present invention is such that the whole must be baked and processed with a paste food such as hamburger or kamaboko,
Solid such as some buns and confectionery that requires a process in which something for seasoning must be applied or sprinkled on the surface, such as buns and solids that have an appropriate size and shape, rather than powder Items that are more efficient when collectively carried out on a conveyor in the middle of the carrying process, rather than being supplied in a single row from the feeder. , So that the conveyors are re-arranged to the full effective width and conveyed, and those that are re-arranged and the conveyance density is increased can be collectively and appropriately processed. The present invention is intended to provide a conveyor for arranging conveyed articles having a different configuration.

(Prior Art) As a means for carrying and carrying a conveyed product over the width of the conveyor, if the conveyed product is in the form of powder, even if there is only one supply port, it will naturally spread over the width of the conveyor. Therefore, even without special consideration, it is possible to efficiently convey a conveyed product over the width of the conveyor, but the conveyed product has a proper size and shape, for example, a conveyed product such as a hamburger. In the case of, when the conveyed objects are supplied onto the conveyor from one supply port, the conveyed objects are supplied only in a line at a constant interval on the conveyor, and the conveyed objects are never arranged in the width of the conveyor. Cannot be supplied.

Therefore, if it is attempted to supply these conveyed products so as to fill the width of the conveyor, a plurality of supply ports are provided within a width dimension corresponding to the width of the conveyor, and the conveyed products are successively conveyed from the plurality of supply ports. If it is uneconomical or inconvenient to supply the above items or to form a plurality of supply ports, and there is no choice but to supply the conveyed goods from one supply port, Combine the other conveyor so that it is orthogonal to the desired conveyor below the mouth, and move the conveyor desired to the supply opening in the conveyor back and forth within the width direction of the other conveyor The only way to do this is to rearrange them.

As provided so far to realize the latter means, a part of the belt conveyor is slackened, and the slack part is enlarged or reduced to expand or contract the tip on the conveyor conveying direction side. There is a so-called accumulation conveyor.

However, this conveyor has a complicated structure for increasing or decreasing the slack of the slackened belt, and since the tip that expands and contracts must be synchronized with the movement, In addition to the need for a more complicated structure, the cost of the entire manufacturing line is naturally high, which is a major drawback.
The complicated structure may be disadvantageous in terms of maintenance, and may be limited to use in an environment with little water, hot air, and dust for maintenance.For example, hamburger or kamaboko It can be said that it is almost inconvenient to adopt it in the manufacturing process where there is a lot of water and hot air like in the food manufacturing process such as, and moreover, cleaning and inspection for disinfection management must be frequently performed. It was not there.

In view of the above circumstances, the present invention has succeeded in developing and realizing a conveyor for arranging a conveyed object having a very novel structure having the following structure. A detailed description will be given with reference to the drawings showing various embodiments.

(Structure of the Invention) As can be clearly understood from the representative embodiment shown in the drawings, the conveyer array conveyor of the present invention is a supply side conveyor 2 that is combined with a conveyer feeder 1. On the other hand, while the conveyors 4 are arranged at positions separated by a predetermined distance so as to be lower than the height of the conveyor 21 in the conveying direction that intersects the conveying direction of the conveyors 2 on the supply side, Between the side conveyor 2 and the conveyer side conveyor 4, below the supply side conveyer 2 and above the conveyer side conveyor 4 in parallel with the supply conveyer 2 and combined with a carriage 31 and the like. A relay conveyor 3 which is movable in the lateral direction as a whole is arranged so that the relay conveyor 3 as a whole can be controlled to move so that its tip end reciprocates in the width direction of the conveyance surface of the conveyance side conveyor 4. Together with In back-and-forth movement travel of the entire relay conveyor 3 by 31, etc., during the forward running is stopped conveying surface, during backward traveling, the moving speed of the carrier 32 conveying surface of the conveying side conveyor direction
Vd is greater than the reverse traveling speed Vc and the difference (Vd-V
It is a conveyor for arranging conveyed objects in which c) is regulated so as to have a value substantially equal to the forward traveling speed Vb.

If the conveyed product A is a kneaded food such as hamburger or kamaboko, the conveyed product feeder 1 extrudes the kneaded product,
It becomes a supply device, and if it is an object such as a machine part, it will be provided by different supply means depending on the conveyed product A to be supplied, such as a device for sending out individual products one by one.

Supply side conveyor 2, relay conveyor 3, transfer side conveyor 4
In addition, any known conveyor, that is, a belt conveyor, a roller conveyor, a slat conveyor, or the like can be adopted, and the most suitable one is selected according to the type of the conveyed product A, the convenience of the manufacturing process, economic efficiency and various conditions. It only has to be selected.

The supply side conveyor 2 is provided below the conveyed product supply device 1 by the supply device 1.
It has a function of directly receiving the conveyed product A supplied from the above and sending it to the relay conveyor 3, and is arranged so as to be continuously conveyed in a fixed direction at a predetermined speed Va.

The relay conveyors 3 are arranged in parallel below and close to the supply-side conveyor 2 so as to align the supplied articles A, A, ... On the transfer-side conveyor 4 in a predetermined alignment state. An appropriate means for supporting the entire conveyor 3 without impairing the conveyor function and enabling lateral movement, for example, means other than a means such as a trolley 31 as in the embodiment described later, and a known lateral movement mechanism. Predetermined speed in the front-back direction
It is formed such that it is repeatedly moved by Vb and Vc (usually Vb = Vc), and the conveying operation of the conveyor 3 is interlocked with the repeated movement in a predetermined relationship.

That is, the interlocking relationship between the repeated movement of the entire relay conveyor 3 in the front-rear direction and the conveyance operation of the conveyor 31 of the conveyor 3 is determined by a predetermined speed in the forward direction in the repeated movement of the entire conveyor 3 in the front-rear direction. During traveling at Vb, that is, until the leading end of the conveyor 3 in the transport direction reaches the vicinity of one side edge across the transport-side conveyor 4, the transport operation of the transport body 31 is stopped,
As the conveyor 31 of the relay conveyor 3 is in the conveying operation by the forward traveling of the entire conveyor 3, the conveyors A, A, ... Which are successively sent out from the supply side conveyor 2 are conveyed. It should be received on the surface and arranged in a line at regular intervals.

Then, the transport operation of the transport body 31 is started only when the entire relay conveyor 3 is switched from forward traveling to backward traveling, and the leading end of the relay conveyor 3 in the transport direction is retracted to the full width of the transport side conveyor 4 and again. The transfer operation is continued until it is switched to the forward traveling. The transfer speed Vd of the transfer body 31 at this time is set to the relay conveyor 3
Relative speed (Vd-Vc) of the carrier 31 by realizing the sum of the forward speed Vb and the backward speed Vc of V, that is, the relationship of Vd = Vb + Vc
Is Vb, and even when the relay conveyor 3 is moving backward, the articles A, A, ... sent out from the supply side conveyor 2 are lined up on the conveyor 31 at the same predetermined intervals as when they are moved forward. As a result of the conveyance operation of the conveying bodies 31 arranged side by side, the conveyed articles A, A, ...
Is sent out onto the carrier 31 of the conveyor 4 on the carrier side.

The transport-side conveyor 4 has a transport surface having a width approximately equal to the forward-backward travel stroke value of the relay conveyor 3, and is arranged below the relay conveyor 3 such that the transport direction crosses that of the relay conveyor 3. .. are arranged on the carrier 41 by the forward / backward movement of the relay conveyor 3 and the intermittent transfer operation of the carrier 31, and the objects A, A ,. The continuous transfer operation is performed at the speed Ve.

Specific examples shown in the drawings will be described below.

(Embodiment 1) The embodiment shown in FIGS. 1 to 4 is a conceptual diagram showing one adapted to be used in a hamburger manufacturing process, and a specific structure will be described by this embodiment. To do.

As shown in the plan view of FIG. 1 and the side view of FIG. 2, a supply side conveyor 2 is substantially horizontal under a hamburger feeder 1 for supplying a hamburger-shaped paste (formed hamburger dough A). To be combined. In the case where the feeder 1 is designed to supply a predetermined number of, for example, 30 shaped hamburger doughs A, A, ... For each of these shaped hamburger doughs A, A ,. If the size corresponding to the direction is, for example, about 100 mm, considering the mutual distance of about 10 mm, the setting speed Va of the supply side conveyor is (100 mm + 10 mm) × 30 pieces / minute, that is, 3.3 m / min.
To carry out continuous transfer operation.

Then, below this supply side conveyor 2, a relay conveyor 3 is arranged in parallel so that the whole is moved forward and backward.

The relay conveyor 3 has limit switches before and after the track,
If a predetermined forward / backward stroke value is set, for example, 500 mm (a value approximately equivalent to the effective width of the conveyor 4 on the conveying side described later) by combining sensors, etc. And the carriage 31 has a predetermined forward speed Vb and reverse speed Vc.
If it is attempted to rearrange (in the embodiment, Vb = Vc) four rows within a stroke value of 500 mm, for example, the forming hamburger dough A, A, ...
... is 30 / min = 1/2 seconds in the above value,
It is necessary to move 500 mm in 8 seconds with 4 pieces, Vc
(= Vb) is planned to perform forward / backward traveling at 500 mm / 8 seconds, that is, 3.75 m / min. When the forward traveling is completed and the vehicle travels backward, the switch mechanism is appropriately connected (linked to the limit switch). Relay conveyor 3 by mechanism)
Is designed to operate the carrier 32 of

At this time, that is, when the carriage 31 starts traveling backward from the state shown in the plan view of FIG. 3 and the side view of FIG. 4 (reverse speed Vc = 3.75 m / min in the example), the conveyor 4 on the conveying side
The delivery speed of the forming hamburger dough A to the
If the forward speed Vb is set to 3.75 m / min, the transfer speed Vd of the transfer body 32 on the relay conveyor 3 is set to (Vb + V
c), that is, (3.75 m / min) × 2 = 7.5 m / min, and its relative speed V is (Vd−Vc) = {(Vb + Vc) −Vc} = Vb, that is, 3.75
Try to achieve m / min.

Figure 5 shows this relationship in a graph.
The same (a) shows the speed system of the carriage 31, the same (b) shows the speed system of the carrier 32, and the same (c) shows the speed system of the relative speed V, both of which are the vertical axis and the horizontal axis. I'm taking time.

In this way, when the carriage 31 travels forward, even when the relay conveyor 3 is stopped, a state similar to that when the carriage 32 of the relay conveyor 3 is substantially operating at the speed Vb at the carriage forward speed Vb is realized. Then, the forming hamburger dough A, A, ... from the supply-side conveyor 2 is received on the carrier 32 so as to produce a single-row single-row production, and when the carriage 31 travels backward, the carrier 32 is trolleyed. The relative speed V is realized by operating faster than the retreat speed Vc of 31, and the relative speed V is set to Vb so that the formed hamburger dough A, A, which is a conveyed product, at the same speed as the carriage forward speed Vb. .. from the conveyor 2 on the supply side to the carrier 32
While being received above, the carrier 32 is sent out to the conveyor 4 on the carrier side.

The back-and-forth running of the trolley 31 is a known reciprocating drive method, such as a chain, a timing belt, a rack and pinion, a screw,
Realized with a combination of ball screws, etc.
A clutch is used to actuate the carrier 32, which operates intermittently in synchronism with the forward / backward traveling of 31.

(Advantageous Effects) The conveyor for arranging conveyed articles according to the present invention having the above-described structure has the functions of firing, painting, spraying, seasoning, coloring, etc. during the process of moving the conveyed articles A, A, .... When incorporating a processing step, the number of supply ports of the supply device 1 is not increased as it is, and the conveyed objects A, A, ... Is an excellent conveying device that enables efficient implementation of the above-mentioned processing steps, and is provided between the supply-side conveyor 2 and the transfer-side conveyor 4 arranged such that the conveying directions intersect. , The relay conveyor 3 formed so as to be movable back and forth is arranged, and the intermittent operation of the carrier 32 is synchronized with the forward and backward movement of the conveyor 3, and the transfer speed is regulated to a predetermined relationship. Realized by the extremely simple structure Is shall.

Therefore, it is possible to easily install it in the existing feeder 1, and it is possible to reduce malfunctions during operation and it is convenient for cleaning and inspection work, which is advantageous in terms of maintenance. . In addition, all the conveyors 2, 3 and 4 are all known transporters that have the properties of the transported objects A, A, ...
For example, it has a great feature that it can be selected and used from various types of conveyors such as belts, conveyors, slats, steel belts, rollers, etc. Like the accumulator, there is no inconvenience such as being limited to a special carrier, and it can be extremely versatile, for example, outside the hamburger mentioned in the examples, such as kamaboko and bamboo rings. Not only as a conveying device for other whole foods that have to be baked and processed, but also for applying or sprinkling something for seasoning or decoration on the surface such as some kind of bun or confectionery. Items that require such processes, and other mechanical parts, must be cleaned and dried after the painting process during transportation. As such until those in Migihitsuji, it becomes capable of handling a number of applications.

Further, the crossing angle of the conveying direction of the conveying side conveyor 4 with respect to the conveying direction of the relay conveyer 3 is not a right angle as shown in the figure but is appropriately shifted by an angle so that the conveyed articles A are arranged on the conveying side conveyor 4. , A, ... can be easily changed, and it becomes extremely easy to adjust the processing work in the processing process combined in the middle of the conveyor 4 to the ideal condition. .

In the embodiment, the forward speed Vb and the backward speed Vc of the carriage 31 are set to the same value, but the transfer speed Vd of the transfer body 32 on the relay conveyor 3 is illustrated. There is a difference between Vb and the reverse speed Vc,
Even when the arrangement of the articles A, A, ... on the conveyor 4 on the conveying side is disturbed due to a slight timing deviation of the intermittent operation, the conveying speed Vd of the conveyor 32 is adjusted, If only the relative speed V is properly handled, the arrangement on the transport side conveyor 4 can be easily returned to the optimum state.

As described above, the present invention is excellent not only in the array performance but also in the manufacture of the device, the grounding of the assembly, the inspection, the cleaning, the inspection letter, etc. It is expected to be highly evaluated in many fields.
