Description

Dough sheet separator and dough sheet turn to haulage equipment

Technical Field

The invention relates to the field of food equipment. In particular to a dough sheet separating device and dough sheet steering and transporting equipment.

Background

Croissants are widely popular food, and the making process comprises the steps of making dough sheets, cutting the dough sheets, rounding and baking. When a dough sheet is cut, a cutter is usually used to cut the whole dough sheet into a plurality of triangles which are tightly arranged together, and in order to ensure the production efficiency, the whole dough sheet is cut into a plurality of rows and columns of triangles at the same time. In order to prevent the waste of the dough sheets, the triangular dough sheets formed by cutting are continuously arranged together, and the adjacent dough sheets are in different orientations on the same longitudinal row. And the subsequent rounding tools have the same orientation and operation action, which brings difficulty to the rounding process. In the prior art, the turning mechanism is used for turning the dough sheets, so that the final directions of all the dough sheets are consistent, in the turning process, the situation of mutual extrusion can occur between the adjacent dough sheets, so that the dough sheets are deformed, and the turning mechanisms of different dough sheets can also interfere with each other.

In order to solve this problem, a driving mechanism such as an air pump is usually used to separate adjacent dough sheets, for example, when each row includes three dough sheets, two air pumps are needed to drive two dough sheets located at the outer sides of the same row, that is, the two dough sheets located at the two ends move in opposite directions, so that the two outer dough sheets are separated from the middle dough sheet, and thus, during the rotation of the dough sheets, mutual interference does not occur. This kind of drive structure needs to use a plurality of drive arrangement, and every drive arrangement drives a dough sheet respectively, and will set up different drive directions for different drive arrangement, and not only the structure is very complicated, hardly guarantees driven synchronism moreover, simultaneously because the cost of air pump is also than higher, leads to whole mechanism price not very much. While the above example is an example of cutting only three sheets per horizontal row, the above structure cannot be applied to the case of cutting four or even five rows of sheets at the same time because not only the sheet on the outer side needs to be separated from the sheet on the inner side, but also the sheets on the inner side need to be separated from each other, and there is still a problem of mutual interference between the two sheets on the same side. The prior art has limited the efficiency of cutting and turning to the process to the production efficiency of whole ox horn bread production line has been reduced.

In the present embodiment, the dough pieces are triangular dough pieces, and the orientation of the adjacent dough pieces cut on the whole dough piece is different in the conveying direction of the first conveyor belt 3, and as shown in the figure, the angle between the two is 180 °, so that the orientation of the adjacent dough pieces when the gripping device grips the adjacent dough pieces is also different. During one rotation of the cylindrical cam 62, the disc cam 73 rotates half a revolution, that is, during one rotation of the disc cam 73, the same gripping device grips two adjacent dough pieces with different orientations and turns the two dough pieces to the same direction, and the two dough pieces rotate 90 ° counterclockwise and 90 ° clockwise, respectively. The transmission scheme is as follows: one end of the first cam shaft 61 is provided with a first gear 68, one end of the second cam shaft 71 close to the first cam shaft 61 is provided with a second tooth 78 engaged with the first gear 68, and the diameter of the second tooth 78 is 2 times that of the first gear 68. The separation motor 51 is decelerated by the reduction box to drive the first gear 68, and the first gear 68 drives the second gear 78.

The specific process is as follows:

in the initial position, the separating bogie 5 is located above the first conveyor belt 3, the separating unit 8 is located above the dough sheet 21, and the separating bogie 5 does not move. The second bearing 72 moves in the first segment 6211 of the first track 621, the separation unit 8 does not move on the separation guide 64, the fourth bearing 77 moves in the first portion 73111 of the first segment 7311 of the second track 731, the rack 76 does not move in the dough sheet conveying direction, and therefore the separation unit 8 does not rotate. The lifting drive device 82 drives the needle plate 83 to descend, so that the fixing needles 84 are inserted on the dough sheet 21, and the action of grabbing the dough sheet is completed.

When the separating bogie 5 moves from above the first conveyor belt 3 to above the second conveyor belt 4, the second bearing 72 moves in the second segment 6212 of the first track 621, and the separating unit 8 drags the dough sheet 21 to move along the separating guide 64 in a direction away from the middle of the guide. At the same time, the fourth bearing 77 moves in the second portion 73112 of the first segment 7311 of the second track 731, the fourth bearing 77 is away from the axis of the second cam shaft 71, the rack 76 moves toward the gear to rotate the gear, and the separating unit 8 is dragged to rotate along the sheet surface until the separating unit 8 rotates 90 °.

Thereafter, the separating bogie 5 stops moving, the fourth bearing 77 continues to move into the third portion 73113 of the first segment 7311 of the second track 731, and the separating unit 8 stops moving on the separating track. At the same time, the second bearing 72 also moves into the third segment 6213 of the first track 621, and the gear stops rotating. The lifting drive device 82 drives the needle plate 83 to move upwards, so that the dough sheet 21 falls on the second conveying belt 4, and the direction of the large end of the dough sheet is consistent with the conveying direction of the dough sheet.

Thereafter, the separating bogie 5 moves from above the second conveyor belt 4 to above the first conveyor belt 3, while moving the second bearing 72 into the fourth section of said first track 621 and continuing the movement, the separating unit 8 moves on the separating track to a position near the middle thereof until it returns to its initial position. At the same time, the fourth bearing 77 enters the fourth portion 73114 of the first segment 7311 of the second track 731 and continues to move away from the first cam shaft 61 of the disc cam 73, the gear wheel resumes rotation until the separating unit 8 rotates another 90 ° and the direction of rotation coincides with before.

The separating bogie 5 then stops moving, the second bearing 72 enters the first section 6211 of the first track 621, while the fourth bearing 77 enters the fifth part 73115 of the first section 7311 of the second track 731 and the fifth part 73125 of the second section 7312 of the second track 731, the separating unit 8 being located above the first conveyor belt 3 and neither moving nor rotating. The elevation driving device 82 drives the needle plate 83 to descend, so that the fixing needles 84 are inserted on the dough sheet 22, and the action of grabbing the dough sheet 22 is completed. This dough sheet 22 is shown adjacent to the dough sheet 21 being pulled onto the second conveyor 4 at the same position as the dough sheet 21 was pulled, except that the dough sheet 22 is oriented differently than the dough sheet 1.

The separating bogie 5 is then moved from the first conveyor belt 3 towards the second conveyor belt 4, while the second bearing 72 enters the second segment 6212 of the first track 621 and the fourth bearing 77 enters the fourth segment 73124 of the second segment 7312 of the second track 731, away from the axis of the second cam shaft 71, and the separating unit 8 moves towards the end of the separating track while rotating in the opposite direction until-90 ° of rotation.

Then the separation bogie 5 stops moving, while the second bearing 72 enters the third segment 6213 of the first rail 621, the fourth bearing 77 enters the third portion 73123 of the second segment 7312 of the second rail 731, the separation unit 8 neither translates nor rotates above the second conveyor 4, the lift drive 82 drives the needle plate 83 to rise, and the dough sheet 22 is stopped by the baffle 85 and falls off the fixing needle 84. The large end of patch 22 is in the same direction as patch 21 and patch 22 is behind patch 21.
