Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a depositor for squeezing confectionery material dough onto a baking sheet into a predetermined shape.

Conventionally, in this type of depositor, a belt conveyor that transfers the top plate in one direction has been used as a transfer mechanism for the top plate. In this case, the worker places the top plate on the belt conveyor from before the depositor and operates the conveyor and squeezing mechanism to squeeze out the dough, but the top plate with the squeezed dough is placed on the other side of the depositor. Since the baking sheet was sent out to the top and was out of reach of the worker who inserted it, another worker would pick up the top plate and transfer it to the conveyor for the next process, such as a baking oven, which required manual labor. . Moreover, when a different shape and type of dough is layered and squeezed on top of the dough that has been squeezed out onto the top plate, it is not easy to align the dough.

The object of the present invention is to eliminate these drawbacks of the conventional ones, and to provide a depositor that allows a single worker to insert and remove a top plate, and also allows for accurate and easy overlapping drawing. It is something to do.

The present invention comprises a dough hopper for introducing confectionery material dough, which is equipped with a pair of rolls held in parallel and supported so as to be able to rotate in reverse, and a top plate on which confectionery material dough squeezed out by the rolls is placed. , a depositor having a transfer mechanism for transferring the top plate,
The transfer mechanism includes a reciprocating guide that is intermittently driven by a drive device that intermittently moves forward at a desired stroke pitch in conjunction with at least the rotation of the roll;
a drive device that returns the reciprocating guide to the previous position by a quick return motion, the pair of rolls supported so as to be rotatable in reverse, a ratchet wheel that intermittently drives the reciprocating guide in conjunction with the rotation of the rolls;
The depositor is characterized in that it is equipped with an electromagnetic ratchet that engages and disengages from the ratchet wheel, and a switching mechanism that selects and reverses the roll.

The present invention will be explained with reference to the drawings based on examples.
There are two types of confectionery material dough: kutsky dough, which has a relatively low moisture content, and water-based dough, which has a high moisture content, but the following explanation will mainly be based on the case of kutsky dough.

The depositor is broadly divided into a main body 1 and a diaphragm mechanism 2 mounted on the main body 1, as shown in FIG.
The squeezing mechanism 2 squeezes the fabric put into the hopper 3.
The dough is squeezed downward from a plurality of nozzles 4 at the bottom, and the main body 1 is for linearly reciprocating movement in a forward direction 6 and a backward direction 7 of a top plate 5 that receives the squeezed dough.

The aperture mechanism 2 will be explained.

For example, to explain in detail the operation for shoe-skiing dough, first, the top plate 5 is set on the reciprocating guide 35, and after adjusting the position of the shoe-skiing dough squeezed from the nozzle 4 and the front-to-back position and vertical position of the top plate 5, When the motor 33 is started, the rolls 8 and 9 are rotated, and the cookie dough put into the dough hopper 3 is squeezed out from the mouthpiece 4 and formed onto the top plate 5 set on the reciprocating guide 35. When a certain amount of kutsky dough is squeezed out from the nozzle 4, the rotation of the rolls 8 and 9 is stopped, and the reciprocating guide 35 descends by a predetermined amount and then starts forward movement of the desired stroke pitch. When the reciprocating guide 35 moves forward at the desired pitch and the top plate 5 is fed, the reciprocating guide 35 rises, the rolls 8 and 9 rotate again, and the kutski dough is squeezed out from the nozzle 4 and formed onto the top plate 5. be done.

By repeating the above driving operation of the cam and crank, the top plate 5 moves forward intermittently and receives a predetermined amount of squeezed shoe dough. When the top plate 5 has finished squeezing and reached the final point, the limit switch is activated to start the motor 34, and the reciprocating guide 35 returns to the hand due to the quick return movement, and the top plate 5 is restored to the initial position of the operation.

In this case, the rotation of the rolls 8 and 9 and the reciprocating guide 3
5 and the intermittent feeding of the reciprocating guide 35 are driven by a motor 33, and the quick return movement of the reciprocating guide 35 is performed by another motor 34.

Further, adjustment of the vertical movement of the reciprocating guide 35, that is, adjustment of the distance between the base 4 and the top plate 5, can be performed using the handle 97, and adjustment of the stroke pitch of the intermittent movement of the reciprocating guide 35 can be performed using the dial 135, and the adjustment of the distance between the base 4 and the top plate 5 can be performed using the dial 135. The amount of squeezed dough can be adjusted using the handle 55.

Therefore, when operating, adjust the adjustment parts such as the handle 55, handle 97, and dial 135 in advance, pull the reciprocating guide 35 to the closest position, set the top plate 5, and start. The top plate 5 receives the predetermined squeezed dough while repeatedly descending, moving forward, and rising intermittently, and after finishing the squeezing, the top plate 5 quickly returns to the operator's hand with a quick return operation, making it easy for one person to clean the top plate. Can be moved.

Furthermore, since the position of the top plate 5 is accurately determined by the positioning tool 126, it is possible to overlap the sheets and squeeze them again. Also, automatic driving is easy.

The above example is for kutski dough, but in the case of a water tank with a lot of moisture, a pair of gear-shaped rolls are interlocked like a gear pump (in the case of kutski dough, they are spaced apart), The outside of the roll is sealed with a casing, and a throttling mechanism such as a gear pump that sends a drop of water between the roll and the casing can be prepared in advance and replaced with this. Since the rotation of the roll is opposite to that for kutsky dough, it is only necessary to operate the gear 78 (FIG. 10) to reverse the rotation. In the above embodiment, the gear 78 is engaged with the sprocket 77 by the jaw clutches 81 and 82 when the cloth is made of kutsky, and the gear 78 is engaged with the gear 80 when the material is made of water.

The aperture mechanism 2 can be easily attached and detached using pins 13, 14, and 17, and the geo-clutch 20,
21, sliding drive shafts 22 and 23, and the inclusion of a reversing mechanism, the same main body 1 can be used to easily work with kutski fabrics, water bowls, and other types of fabrics. It became like that. Conventionally, it was necessary to prepare a depositor specifically for each fabric, so this is extremely effective.

The reciprocating guide 35 is one that can reliably move the top plate 5 at a predetermined pitch by pushing or pulling the top plate 5, and is equipped with a positioning tool that can ensure positioning. A variety of reciprocating belt conveyors can be used.

The present invention provides a reciprocating guide in which a transfer mechanism for transferring a top plate is intermittently driven by a drive device that moves forward intermittently at a desired stroke pitch in conjunction with at least the rotation of a roll, and a reciprocating guide that is moved in a fast return motion. By being equipped with a drive device that returns to the previous position, the top plate placed on the reciprocating guide returns to the hand by a quick return movement when squeezing is finished, and the top plate quickly returns to the initial position of the operation. In addition to demonstrating high performance, loading and unloading of the top plate can be performed only from the front of the entire device, allowing one worker to do it, which not only contributes to labor savings, but also saves installation space and is more compact. In addition, the roll that squeezes the confectionery material dough onto the top plate is rotated slightly by switching the electromagnetic ratchet at the same time that a certain amount of dough has been squeezed out and the reciprocating guide starts to be driven intermittently, and the roll that squeezes the confectionery dough onto the top plate. Therefore, it has extremely great effects such as preventing the dough from sagging and making it easier to cut.
