Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tenpan (pan) in a confectionery and bread manufacturing apparatus.
) regarding a mechanism for transferring bread dough balls.

Conventional sweet bread manufacturing apparatuses include the following types, but each of them has the following problems. '1} Panning is performed by manually dividing one batch of tenpan into groups and dropping them onto the tenpan waiting below with a shirt conveyor.

This method has the disadvantage that the balls of dough must be manually arranged and grouped, which takes time. ■
The conveyed bread dough is received by a V-shaped dough holder consisting of two plates placed below the conveyor exit end at right angles to the direction of conveyor movement, and by opening these plates,
The dough is dropped onto the tenpan that has moved downward, then the plates are closed and the tenpan is sent one pitch, and this is repeated to arrange the dough in a grid pattern on the tenpan and pan.

There is no advantage to this method other than (a) loading the goods on a tenpan according to the row spacing between the balls being transported.In other words, depending on the shape of the dough balls, it is not possible to place them diagonally or in a staggered manner. It is not possible to increase the efficiency of the device because it is not possible to arrange them effectively on a surface, that is, to save space.

[b-Suitable for bread rolls and coppépan-like items,
If the bread is soft or has a filling, such as jam bread or cream bread, the appearance may deteriorate as the filling protrudes or the top and bottom orientation is disturbed or deformed. [3- A conveyor for conveying bread dough that has a roller or a device for popping out bread dough at one end (Japanese Patent Application Laid-Open No. 129178/1983).

However, this is also due to the interval at which it was transported.
There is no advantage other than placing the dough on the tenpan, so it is not possible to increase the efficiency of the device by placing the dough diagonally or arranging it in a staggered manner. 'b' Since the dough is made to pop out, there is a risk that the filling of the dough will shift or be crushed, resulting in loss, which is undesirable. The present invention utilizes a unique mechanism that eliminates the drawbacks of the conventional devices described above, and allows balls of dough to be arranged not only in a lattice pattern, but also in a diagonal or staggered pattern, depending on the size of the tenpan and the number and shape of the dough balls to be placed. The present invention provides a dough ball transfer mechanism that can maximize the operational efficiency of the device by arranging the dough balls.

In particular, arranging bread dough balls diagonally causes mechanical misalignment due to the characteristics of the dough, and changing the dough balls causes deformation of the dough, which is difficult, but the present invention provides a device that solves this problem. It is something to do. That is, in order to solve the problems of the conventional technology, the present invention provides a conveyor that supports and conveys dough balls arranged in multiple rows, and a group conveyor that is driven intermittently to support and convey multiple rows of dough balls. A bread dough ball transfer system consisting of a group conveyor followed by a multiple row rotatable conveyor, a private conveyor whose tip can be moved downwards, and a chain conveyor that supplements the tenpan. It is characterized by providing a mechanism.

Furthermore, the present invention includes a conveyor that supports and conveys dough balls arranged in a plurality of rows, a group conveyor that is driven intermittently and that supports and conveys a plurality of rows of dough balls, and a conveyor that follows the group conveyor and is divided into groups. After softening the dough balls, a plurality of rows of revolving conveyors that can be rotated, and the groups of dough balls that have been divided into groups are transferred from the revolving conveyor, the conveyor is following the revolving conveyor and its tip can be moved downward. The present invention is characterized by providing a bread dough ball transfer mechanism which is provided with a stack conveyor and a chain conveyor for loading tenpans.

The present invention also provides that, beside the dough ball transfer machine, each row of the multiple rows of revolving conveyors has an independent drive device, and the conveyors of each row are arranged to move the dough balls at different transfer start times. The present invention is characterized by providing a bread dough transfer machine that can transfer bread dough and balls.

The present invention further provides the movement of the tenpan by the chain conveyor loaded with the tenpaso, the transfer of the grouped dough balls by the moving conveyor, the downward movement of the tip of the moving conveyor, and the return to the horizontal position. The present invention is characterized by providing a mechanism for transferring bread dough balls in response to the situation.

A further feature of the present invention is to provide a bread dough ball transfer machine in which each of the plurality of rows of revolving conveyors is arranged to be able to rotate independently or partially in conjunction with each other.

The present invention will be explained below with reference to embodiments.

According to Figures 1 to 4 of the accompanying drawings, a group conveyor 5 using an intermittent drive method is used in the next step of the conveyor for conveying confectionery dough arranged in multiple rows or in a lattice shape in each vertical and horizontal direction.
In this step, the rows of dough balls for one tenpan are divided into groups, and multiple rows of rotating rows that can be rotated around the tip of this group conveyor with respect to the belt conveyor 9 provided in front of the frame conveyor 11 are provided. Conveyor 7 is installed next to it. The plurality of rows of revolving conveyors 7 rotate around the intersection of the tip of the group conveyor 5 and the dough ball conveyance center line of each row, so that the leading end of each revolving conveyor 7 is connected to the next belt conveyor 9. Turn all the way and stop.
A moving conveyor 11 is provided following the belt conveyor 9, which conveys the dough balls from a direction perpendicular to the flow thereof, and conveys the dough balls from a direction perpendicular to the flow of the dough balls.
7 and is conveyed to the cage conveyor 11 until it touches the bottom of the balance sheet, which is waiting at the bottom of the tip of the monkey movement conveyor 11.
The tip of the dough moves down to transfer and arrange the dough balls on a tenpan and transport them to the next process such as an oven. In this case, the tips of the multiple rows of rotating conveyors 7 are
There are steps of a certain size in the direction of movement of the rotating conveyor 7, and since the above direction of movement is oblique to the direction of movement of the belt conveyor 9 at the end of the turn, at this time, the steps are set according to the angle and the above-mentioned dimensional steps. The dough ball becomes narrower in the direction perpendicular to its flow.

Therefore, the reduction ratio in each row of bun dough balls can be changed by changing the length of each conveyor of the turning conveyor 7 when the turning angle of the turning conveyor 7 is constant. By changing the timing at which conveyance is started from each row of the multiple rows of revolving conveyors 7 to the belt conveyor 9, it is also possible to arrange the conveyance on the belt conveyor 9 in a lattice pattern. The phase of the row of dough balls from the th conveyor is advanced by half a pitch, and each ball of dough from the row of dough balls from the even-numbered conveyor is placed diagonally horizontally in the middle of each ball of dough from the row of dough balls from the odd-numbered conveyor. Since it is possible to arrange and transport them, it is possible to form a so-called staggered arrangement as a whole, and then move on to Tenpan.

Further, when the revolving conveyor 7 is left in a pre-swivel state and a row of dough balls of one group is conveyed thereon, the revolving conveyor 7 is turned and the dough balls are transferred onto the next belt conveyor. are arranged diagonally to the direction in which they were initially conveyed.

A moving conveyor is provided adjacent to the belt conveyor, and this is conveyed from the side to the lower part of the belt conveyor 9, and is conveyed by changing direction in the same direction as the belt conveyor 9, and conveying sweet bread dough balls. This is for transferring rows of groups without damaging the fabric.

That is, when a group of sweet bread dough balls is loaded onto the conveyor conveyor 11, the tip of the conveyor 11 is moved until it touches the bottom of the temporarily stopped tenpan due to the action of the sensor phototube, limit switch, etc. that detect this. On the way down, the tenpan moves at approximately the same speed as the transfer conveyor due to the operation of the timer, and the row of sweet bread dough balls is transferred onto the tenpan. Immediately before the end of this transfer of one group, the tip of the moving conveyor is raised by the operation of a cam or the like to prevent the tip of the conveyor from touching the post-temperature green, and returns to the horizontal position, and the above-mentioned shifting operation is repeated.

Dough balls 1 for sweet breads are first wrapped in a wrapping machine (not shown) with bean paste, etc., wrapped therein as required, and conveyed in multiple rows (four rows in this embodiment) from a conveyor 3 at the exit of the wrapping machine. Then, they are transferred to the group conveyor 5 at the front stage of the vanning device 10, and are once assembled into groups.

Next, the bun dough balls 1 are initially transferred from the group conveyor 5 to a straight-on swivel conveyor 7, shown in FIG. Next, the ball of dough 1 is transferred to a conveyor 11.
and is further carried by the chain conveyor 13 that crosses and moves under the belt conveyor 9, and then on the ten bun 15, which waits at the bottom of the transport conveyor 11 and is conveyed in synchronization with the group of dough balls. will be moved to The balance pan 15 is transported to an oven or the like (not shown). As shown in FIG. 2, the group conveyor 5 is separately and intermittently driven by a geared motor 21 and a clutch/brake device 23, and the turning conveyor 7 is also individually driven by a motor 25, a reducer with a clutch/brake 27, etc. Ru. In addition, the hydraulic cylinder 2 shown in FIG.
9 and the interlocking punch 31, from the position 7' facing the flow line of the wrapping machine exit conveyor 3 and the group conveyor 5, the batch of dough balls is finished and rotated towards the position 7. move. The revolving conveyor 7 returns to the position 7' after completing the transfer of the dough ball group to the belt conveyor 9. The belt conveyor 9 is driven by a geared motor device 33, the mirror conveyor 11 is driven by a geared motor 35, and the chain conveyor 17 loaded with a tenpan 15 and moving in the direction of the flow of the dough balls 1 is driven by a variable speed motor 37 with a reduction gear. Driven. A stopper 46 prevents the advance of the tenpan, and is lowered by a cylinder 47 and a lever 49 which is integrated with the stopper 46 and slidably fitted to a shaft 48, and conveys the tenpan in synchronization with the dough ball group. Close.

When the clutch of the clutch brake 39 is engaged, the cam 50 is rotated, and the rollers 51 and 51 that are in contact with this working surface rotate.
The conveyor 11 is moved as described above through the lever 43 to which it is attached, and the link 45 connecting the lever 43 and the frame of the chain conveyor 11. After returning to the horizontal position, the clutch of the clutch brake 39 is moved. is released, the brake is applied, and the position shown in the figure is reached.

These actuations may be automated by sensor systems such as phototubes, limit switches, timers, etc. as generally discussed above.

3a to 3f represent a series of operating situations in which the turning conveyor 7 changes its arrangement diagonally.

In other words, the situation is shown in which the dough 1 is being transferred from the conveyor 3 at the exit of the packaging machine onto the grouping device 5. When the phototube ph-1 of each row is shielded from light by the dough ball 1, the four rows of group conveyor are operated intermittently at a fixed distance a, and in the figure, the sixth dough ball blocks light from the phototube ph-1, b, and the group conveyor 5 in each row moves the sixth dough ball in the same direction as the group conveyor 5. c is driven by the action of a timer until the conveyor is completely transferred onto the rotating conveyor 7' facing the direction c. When the leading dough ball reaches the photocell ph-2d at the end of the shortest conveyor of the revolving conveyor 7', its feeding is stopped, and the other revolving conveyors each reach the ph-2d of the leading dough ball.
It is driven until it reaches -2a, b, c. The hydraulic cylinders 29 and the connecting punches 31 cause the plurality of rotating conveyors to rotate toward the belt conveyor 9 around the contact point with the group conveyor 5, rotate at a predetermined angle, and stop at the rotating position shown in FIG. 1. By this time, the phototubes ph-2a to ph-2d at the tip of each conveyor are shielded from light by the balls of dough at the tip of each conveyor, and each revolving conveyor has stopped its feeding. Next, the revolving conveyor 7 starts conveying the dough balls in sequence with a time difference so that they are lined up horizontally on the belt conveyor 9, and are arranged in a group shape that is most suitable for transfer to ten-pan on the belt conveyor 9. can be done. Fig. 3 f' All the dough balls 1 are transferred to the rotating conveyor 7.
This shows the situation when the dough balls have been transferred onto the belt conveyor 9, and at this time, a timer or the like is activated again to turn the turning conveyor 7 back to the original position 7' and prepare to receive the next group of dough balls. . In this embodiment, the rotating conveyor 7
The dough balls 1 are placed diagonally according to the angle at which they are rotated, forming a compact group of 4 rows x 6 dough balls. This is extremely effective when making jam bread or cream bread. If the bun dough ball is round, it is not necessary to place it diagonally, but if the turning angle of the turning conveyor 7 is, for example, about 30 degrees with respect to the traveling direction of the group conveyor 5, as shown in FIG. When the turning is completed, the ends of each conveyor of the turning conveyor 7 are aligned in a straight line and stiffened, b: thing', therefore, b bow a. When it is necessary to reduce the interval between each row by 4 mm on the rectangular belt conveyor 9, it is necessary to make a difference in the length of each row of conveyors by c as shown in the figure at the position of the tip when the revolution is completed. This gives b=kia-false in3o.

=Reed a-becomes a cloud. Regardless of the interval between the rows of balls of dough sent in this way, the belt conveyor 9 and the cheek conveyor 11
Accordingly, the interval between each row after being transferred to the tenpan can be set as desired depending on the size of the dough balls and the tenpan size, even if the angle at which the dough balls are placed diagonally is constant. Of course, the distance between the dough balls in the vertical direction can be varied by changing the intermittent feeding time of the group conveyor and by changing the speed ratio of each conveyor. Figure 4 shows a method of arranging bread dough balls 1 in a staggered pattern on a tenpan.
When transferred from the revolving conveyor to the belt conveyor 9, the balls of dough 1 can be arranged in a staggered pattern if each row of dough balls is delayed or advanced by a half pitch every other row.

FIG. 4 shows a situation in which the odd-numbered revolving conveyors are delayed by half a pitch and arranged in a staggered manner. Eventually, by the above mechanism and operation, the compact lattice arrangement as shown in Fig. 5a, the diagonal arrangement of the elongated cloth as shown in Fig. 5b, and the number of arranged pieces on the same tenpan for the same width can be increased, or By arranging them in a staggered manner as shown in Figure c, it is possible to increase the number of products that can be manufactured. When the dough balls that have been efficiently and compactly arranged as described above are transferred onto the pocket conveyor 11, the photocell ph, which serves as a sensor, for example, shown in FIG.
-9, the flap conveyor 11 is activated, that is, its tip is moved to the stopper 4 via the lever 43 and the link 45.
When the first dough ball reaches the top of the conveyor 11 according to the timer, the stopper 11 is lowered and the dough ball group moves in synchronization with the tenpan 16. be done.

Further, as shown in FIGS. 1 and 2, the balance sheet is transferred to the chain conveyor 13 below the belt conveyor 9 as usual.
The panning process described above is completed sequentially from the top of the conveyor 13, and the panning process is performed to open the panning process. FIG. 6 shows another embodiment of the present invention, in which the direction of the exit conveyor 3 of the packaging machine and
This shows a case in which the directions of processes after the turning conveyor 7 are different.

In this example, the direction of flow of the dough balls is changed by about 90° at the turning conveyor 7. The rotating conveyor 7 is in a state parallel to the traveling direction of the group conveyor 5 (state 7' shown by the storm line in FIG. 6), and after the grouped dough balls are transferred from the group conveyor 5, it is rotated at a predetermined angle. death(
In this embodiment, 30o), when the grouped dough balls are transferred to the belt conveyor 9 with a time difference for each row, the direction of the dough balls on the group conveyor 5 or the exit conveyor 3 is By changing the direction of each dough ball by 60° and conveying them, it is possible to arrange them diagonally by 600° even on a tenpan. In this embodiment as well, the conveyor 3,
The interval in the direction perpendicular to the conveyor traveling direction of the rows of dough balls sent on the group conveyor 5 can be changed on the belt conveyor 9 by appropriately setting the turning angle of the turning conveyor T and the length of each conveyor. This not only increases the number of doughs that can be accommodated on the tenpan, but also uniformizes the heating of the dough during baking in the oven, contributing to the sophistication of the product. Although the belt conveyor 9 and the pocket conveyor 11 are separate in the embodiment of the present invention, they may be integrated. If there is no disturbance in the front or rear of the dough ball, each row is not driven separately, but one drive is required.
It is also possible to use several motors and one belt conveyor.

As is clear from the above description, the dough ball transfer mechanism of the present invention achieves the following effects.

[11] After the dough balls are loaded in groups onto a rotating conveyor and rotated at a predetermined angle, the dough balls are automatically arranged in a lattice shape, staggered shape, etc. in the subsequent process by transferring each row with a time difference. Since they can be rearranged and arranged in a compact manner, the utilization efficiency of the tenpan area is greatly improved, which in turn improves the efficiency of firing.

'21 The moving conveyor lowers its tip to the tenpan surface and transfers the dough balls to the tenpan surface, so the bunning process can be performed smoothly without damaging the dough balls, making it possible to manufacture good products with higher efficiency than before. .

[3'] Since all steps of the panning process are automated, it requires almost no manpower and it is possible to reduce the cost of panning.
