Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bread cutting machine that cuts prismatic baked bread into bread pieces of appropriate thickness.

BACKGROUND ART Bread shops often sell bread that has been baked in a prismatic shape and is cut into pieces of appropriate thickness according to customer orders. The bread cutting machine used here consists of a side plate and a bottom plate that are connected in an L-shape, and a mounting table for the bread to be cut that is slightly inclined in the longitudinal direction of the machine and is attached so that it can freely move back and forth with an appropriate stroke. There are many types that include a rotary knife and a cutting size adjustment plate arranged facing the front end of this mounting table, and the mounting table is moved manually to cut the bread. In this type of bread cutting machine, the bread to be cut is fed to the rotary blade by pushing the bread to be cut while the mounting table is in a position facing the cutting dimension adjusting plate, that is, at the position where the mounting table is at its starting point. Alternatively, the table is tilted toward the rotary cutter, so gravity is used to feed the cutter until it touches the cutting size adjustment plate, and the table is then moved to perform cutting.

When cutting is repeated in this way, leaving the ears at the end, it is necessary to press and hold the rear end of the bread on the mounting table. A booster plate is disposed so as to be able to reciprocate in the bread feeding direction, and the booster plate is manually pushed forward, or the booster plate is biased in the bread feeding direction using spring force or gravity, It is configured to automate bread feeding. By the way, although the structure of the configuration in which the pusher plate placed on the mounting table is manually pushed forward as described above is simple, one hand is occupied with feeding the bread on the mounting table during work, and the work becomes difficult. Not only is it difficult to remove, but it is also extremely dangerous as your hands come close to the rotating blade.

On the other hand, with a configuration in which bread feeding is automated by energizing a boosting plate, boosting pressure is constantly applied to the bread to be cut, including during cutting, and this makes it difficult to use soft bread that has been baked to a high degree. The middle part swells into a barrel shape, causing deviations in cut dimensions, and the cut ends are not straight after cutting, which may deteriorate quality and appearance.

The present invention has been made in view of the above points, and the bread to be cut is fed on a mounting table by placing it on an endlessly rotating belt conveyor and driven by a motor, and furthermore, the bread does not move backward. To provide a bread cutting machine which realizes cutting of high-quality bread pieces by applying a pressing plate to the rear end surface of the bread fairly lightly and cutting the last bread piece without applying any force at all.

Embodiments of the present invention will be described below with reference to the drawings.

1 is a machine base, 2 is a mounting table for the bread to be cut A, 3 is a rotary blade arranged facing the front end of this mounting table and connected to a motor 4;
Reference numeral 5 designates a cutting dimension adjusting plate which is also placed in front of the rotary blade 3 facing the front end of the mounting table, and whose distance from the rotary blade 3 can be set freely.

The above-mentioned mounting table 2 is made up of a side plate 2a and a bottom plate 2b arranged in an L-shape with the side plate 2a in front, and the side plate 2a is lowered to form the bottom plate 2.
b has a slight inclination, and reciprocates with an appropriate stroke.

In the present invention, rollers 6 and 7 are pivotally supported at both front and rear ends of the mounting table 2, and an endless belt 8 is hung around the rollers 6 and 7 so that the lower surface of the upper rotating belt is in sliding contact with the bottom plate surface. Also, connect the rear roller shaft 7a to the motor 9 and the deceleration mechanism 1.
A belt conveyor connected through 0 is installed.

The belt 8 of this belt conveyor is made of a non-metallic material in view of the relationship with the permanent magnet piece described later. In the illustrated example, the belts 8 are separated by an appropriate distance and two belts of an appropriate width are arranged in parallel, and the two belts are integrated. Although a rotating configuration is shown, the number of belts, belt width, etc. may be determined as convenient for placing the bread A to be cut.

Reference numeral 11 denotes a guide rod supported on one side of the mounting table via a support member 12 along the belt 8, and 13 is engaged with this guide rod 11 to allow reciprocating movement along the guide rod 11 and movement around the guide rod 11. This plate is provided so that it can be rotated and moved freely toward and away from the bottom plate 2b of the mounting table, and a permanent magnet piece 14 is provided at the bottom of the plate.
When the contact plate 13 is placed in the normal position, the magnetic force of the magnet piece 14 acts as an attractive force between the mounting table bottom plates 2b through the belt 8.

Therefore, the magnet piece 14 of the contact plate 13 is attached to the belt surface on the belt 8.
The contact plate 13 is pressed against the bottom plate surface of the mounting table, and when there is no resistance from the outside, the contact plate 13 also moves following the rotation of the belt 8.

Next, FIG. 3 shows the electrical control circuit for the two motors 4, 9.

In the figure, 15 is a power switch, 16 and 17 are hand push button switches, one switch 16 is installed on the operating handle 18 attached to the mounting table 2, and the other switch 17 is installed at an appropriate position on the machine base. . Reference numerals 19, 20, and 21 are conductive plates provided on the underside of the machine, etc., in alignment with the moving direction of the mounting table 2. Of these, two conductive plates 19, 20
The remaining conductive plate 21 is set to the length of the moving range of
is set to a length within a range in which the mounting table 2 moves a predetermined distance from a position slightly away from its starting point.

Then, sliders 22, 23, 24 that move together with the mounting table 2 are provided opposite to each of the conductive plates 19, 20, 21, respectively.
By simultaneously pressing the two pushbutton switches 16 and 17, the conductive plates 19 and 19, which are always in contact with each other, are
20 and sliders 22 and 23, the motor 4 is continuously energized to rotate the rotary cutter 3, and the slider 24 of the motor 9 comes into contact with the conductive plate 21 as the mounting plate 2 moves. The belt 8 is driven by being energized for a period of time. In the above embodiment, the electric control circuit configuration of the two motors 4 and 9 is shown by a combination of a conductive plate and a slider, but it is also possible to use a micro switch or the like that operates in conjunction with the movement of the mounting table 2 at an appropriate location. It is also possible to assemble other control circuits.

Next, the effect will be explained.

Place the mounting table 2 in a starting position, and place the bread A to be cut on the belt 8.
Put it on top.

At this time, the contact plate 13 may be placed at a distance behind the bread to be cut A, and there is no particular need for the two to be in contact with each other. Here, when the two pushbutton switches 16 and 17 are pressed simultaneously, the motor 4 is activated and the rotary cutter 3 starts rotating.

Next, when the placing table 2 is pushed forward, the motor 9 starts immediately after the placing table 2 leaves the starting point, and the belt 8 rotates to advance the bread A placed on it, and the front end of the bread adjusts its size. After colliding with the plate 5, the belt 8 slides on the lower surface of the pan. Cutting continues due to the movement of the mounting table 2, but just before this cutting starts, the slider 24 comes off the conductive plate 21, the motor 9 stops rotating, and the rotation of the belt 8 stops. The cutting is performed in this state. After cutting, when the mounting table 2 is pulled back to the starting point, the slider 24 and the conductive plate 21 come into contact again on the way, and the motor 9 is energized, causing the belt 8 to rotate and move the bread A forward. When the mounting table 2 reaches the starting point, the rotation of the motor 9 temporarily stops.

Then, when the mounting table 2 is pushed forward, cutting is performed again after the rotation of the belt 8 is stopped under the same operation as described above. In addition, as mentioned above, the bread moves forward due to the rotation of the belt 8 even while pulling the placing table 2 back to the starting point in the middle of the bread cutting operation. In such cases, the reciprocating movement 2 of the mounting table 2
The bread can be advanced in batches, and the scheduled advance can be reliably performed without changing the speed of moving the mounting table 2 or requiring any complicated operations, and cutting can be performed efficiently.

In addition, even if the contact plate 13 is located at a distance behind the bread A to be cut during the cutting preparation stage, when the cutting operation starts, it approaches the bread to be cut A by the rotation of the belt 8 while being attracted to the surface of the belt 8. After coming into contact with the rear end of the pan, the belt 8 also begins to slide on the lower bottom surface of this contact plate. However, when the belt 8 slides on the bottom surface of the plate, the adsorption force between the two is extremely light, and is not used as a bread pushing force. It is needed only as a backup. In the present invention, as described above, each time the mounting table 2 is brought to the starting point, the belt 8 rotates to advance the bread A to be cut to the cutting position, and while cutting is being performed by the rotary blade 3. By stopping the belt 8 and the plate 13 and eliminating the pressing action during cutting, even when cutting evenly baked soft bread, the cut edges are aligned and all the cut bread pieces are accurately cut. A permanent magnet piece 14 is attached to the lower bottom of the plate 13, and this generates a magnetic force between the bottom plate surfaces of the mounting table through the belt 8, so that it can be attracted and moved to the belt surface. Therefore, even when the contact plate 13 is in contact with the rear end surface of the bread A to be cut, unlike conventional push-up plates, there is no push-up action by the contact plate, and only when the last piece of bread is cut. It helps to hold bread stably.
Even if the contact between the rear end of the bread and the plate is uneven, it will not affect the bread pieces being cut at all, and the size of the uncut edges can be kept to a minimum to ensure accurate cutting. This reduces waste, makes cutting preparation easy, and allows cutting work to be carried out efficiently.
