Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a depositor for squeezing confectionery material dough into a predetermined shape onto a top plate.

[Conventional technology]

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 conventional method, the worker places the top plate on the belt conveyor from before the depositor and squeezes out the dough by operating the conveyor and squeezing mechanism. Since the baking sheet was sent out to the other side and could not be reached by the worker who inserted it, another worker had to pick up the baking sheet and transfer it to the conveyor for the next process, such as the baking oven, which required manual labor. Moreover, when squeezing a different shape or type of dough on top of the dough that has already been squeezed onto the baking sheet, it is not easy to align the dough, and it is difficult to align the dough and the water or other types of dough. When using fabrics, a depositor dedicated to each fabric was used, which resulted in large-scale equipment and installation space, which was an economical problem.

The present invention eliminates the above-mentioned drawbacks of the conventional method by using a reciprocating guide that performs a linear reciprocating motion and is provided with a positioning tool for the top plate, and allows one worker to transfer the top plate. It is an object of the present invention to provide a depositor which can insert and take out materials, can accurately and easily perform overlapping drawings, and can squeeze out various kinds of fabrics with the same main body.

[Means for Solving the Problems] The present invention provides a dough hopper for introducing confectionery material dough, which includes a pair of rolls held in parallel and supported so as to be able to rotate in opposite directions, and a dough hopper for introducing confectionery material dough using the rolls. In a depositor having a transfer mechanism for squeezing onto a top plate and transferring the top plate, the transfer mechanism is a reciprocating mechanism that 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. comprising a guide and a drive device for returning the reciprocating guide to the previous position by a quick return motion, the pair of reversely rotatably supported rolls being arranged so as to mesh the gear-like rolls;
It is characterized by comprising a throttling mechanism between a hopper and a hopper disposed on the outside of the roll, a geow clutch for transmitting the rotation of the roll, and a mechanism for switching the rotational direction of the drive device by operating the jyoque clutch. It is a depositor.

〔Example〕

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.

As shown in FIGS. 3, 5, and 8, the aperture mechanism 2 includes a pair of rolls 8, 9 having a large number of axial grooves parallel to their surfaces, fixed to shafts 18, 19, and brackets 10, 11 and is rotatably supported by a bearing 12. The bracket 11 is fixed to a bracket 15 fixed to the main body 1 by pins 13 and 14. Bracket 10 is main body 1
Pin 17 is attached to gearbox 16 which is fixed to
It is fixed at . Since the pins 13 and 17 are on the same axis, once the pin 14 is removed, the aperture mechanism 2 can be rotated around the pins 13 and 17, and the back side can be easily exposed for inspection or inspection.
Parts and units in or around the base 4 can be easily and reliably replaced (such as a base for cutting wire, which will be described later). Furthermore, by removing all the pins 13, 14, and 17, it is easy to remove the entire throttle mechanism 2, and it is easy to replace it with another type of throttle mechanism (for example, a throttle mechanism for a water basin, which will be described later). With only one main body, it is possible to easily adapt to various fabrics and various drawing methods by simply replacing the cap unit and drawing mechanism.

The ends of the shafts 18, 19 are fitted with geode clutches 20, 2.

By reciprocating in the axial direction, the sleeve 30 rotates, and the base 4 rotates.

Next, the main body 1 will be explained with reference to FIGS. 1 to 9.

Motor 33 as a driving prime mover (Figures 4 and 7)
and a motor 34 (FIGS. 2 and 7). The motor 34 is used for the backward stroke of the reciprocating guide 35 (and for fast forwarding the forward stroke), and the motor 33 is used for other operations, that is, for the forward stroke (intermittent feeding) of the reciprocating guide 35, for raising and lowering the reciprocating guide 35, and for moving the reciprocating guide 35 up and down. Used for rotation, mouth rotation, wire cutting, etc.

To explain from the motor 33 side, as shown in FIGS. 4 and 7, the motor 33 is provided with a variable speed pulley 37 that can be adjusted with a dial 36, and a belt 40 is provided between the motor 33 and the pulley 39 of the worm reducer 38. is hung.

First, the drive system for the rolls 8 and 9 will be explained.

As shown in FIGS. 2 and 7, a chain 44 extends from a sprocket 41 provided on one shaft of the worm reducer 38 to a sprocket 43 of an intermediate shaft 42. The intermediate shaft 42 is connected to a gear 45 as shown in FIGS. The gear 45 meshes with a gear 47 that pivotally connects a crank 46.

In FIGS. 2 and 7, reference numeral 48 denotes an adjustment lever, which is fixed to a shaft 49 rotatably supported by the main body 1, and to which a crank 46 is pivotally connected. The adjustment lever 48 has a screw 51 that is rotated by a handle 50.
is provided to move the nut 52. The nut 52 is adapted to be fixed at any position on the adjustment lever 48 by means of a handle 53, and is pivotally connected to a link 57.

On the other hand, an adjustment lever 54 is fixed to the other end of the shaft 49 as shown in FIGS. 1 and 7. Adjustment lever 5

The shaft 61 is rotatably supported relative to the main body 1, rotatably supports the disks 62, 63, and fixes the ratchet wheels 64, 65 and the sprocket 66. Links 57 and 59 are pivotally connected to disks 62 and 63, respectively. Reference numeral 67 denotes an electromagnetic latch attached to the disk 62. When energized, the ratchet is pulled in, and the ratchet foil 64 is unrestrained with respect to the disk 62. When de-energized, the ratchet is pushed out by the force of the spring and rotated in the direction of arrow 68. The ratchet wheel 64 is driven to rotate the sprocket 66 through the shaft 16 in the direction of the arrow 68. Reference numeral 69 denotes an electromagnetic latch attached to the disk 63. When energized, the ratchet is pulled in, and the ratchet foil 65 is unrestrained with respect to the disk 63. When de-energized, the ratchet is pushed out by the force of the spring and rotates in the direction of arrow 70. The ratchet wheel 65 is driven only to rotate the sprocket 66 via the shaft 61 in the direction of the arrow 70.

By operating the handles 50, 55, the nut 52,
By adjusting the position of 60, the ratio of the rotation angles of shaft 49 and shaft 61 can be changed. In this case, when the rolls 8 and 9 rotate and a certain amount of confectionery material dough is squeezed out, the electromagnetic latches 67 and 69 are activated.
Slightly reverse rolls 8 and 9. By slightly reversing the rolls, the confectionery dough is suctioned, thereby preventing the confectionery material dough from dripping and making it easier to cut the confectionery material dough.

Sprocket 66 drives sprocket 72 via chain 71 (FIG. 2). 73 and 74 are sprockets for removing slack.

The sprocket 72 is connected to the shaft 75 as shown in FIG.

Numeral 78 is a gear that can be slid in the axial direction by a sliding key 79, and by sliding, it engages with a gear 80, and by means of gear clutches 81 and 82, it engages with a sprocket 77. A fixed shaft 83 rotatably supports the gear 80 and sprockets 84 and 85. A chain 86 is placed between the sprockets 77 and 85.

By sliding the gear 78, the sprocket 84 can be rotated in the same direction (the gears 81 and 82 are engaged) or in the opposite direction (the gears 78 and 80 are engaged) relative to the rotation of the sprocket 72. .

Sprocket 84 connects to the ninth sprocket via chain 78.
Drive sprocket 88 as shown. The sprocket 88 rotates the roll 9 via the drive shaft 23 and the yoke clutch 21, and at the same time drives the gear 90 that meshes with this via the gear 89, so that the sprocket 88 rotates the roll 8 and the roll 9 via the yoke clutch 20 (FIG. 8). Rotate it in the opposite direction.

Next, the drive system of the reciprocating guide 35 will be explained.

In FIGS. 4 and 7, a bevel gear 91 is provided on the other shaft of the worm reducer 38 and meshes with a bevel gear 92. A shaft 93 is inserted into the bevel gear 92 via a sliding key 94.

The guide rail 125 of the reciprocating guide 35 is guided by sliding between the base plate 127 and the bar 128, and performs linear motion. A plate 129 is attached on top of the base plate 127.

When the drive block 118 reciprocates, it drives the reciprocating guide 35 only when moving in the forward direction 6.
The reciprocating guide 35 is intermittently advanced in the forward direction 6 at a predetermined stroke pitch.

As shown in FIGS. 2 and 8, another motor 34 drives a pinion 134 via gears 130, 131 and bevel gears 132, 133.
This motor 34 continuously drives the reciprocating guide, and is used for fast forwarding in the backward direction, fast forwarding in the forward direction as required, or continuous low-speed feeding (such as when performing long squeezing). At this time, the electromagnet 122 is excited to cause the ratchet 120 to retract.

In FIG. 3, reference numeral 135 is a dial for adjusting the intermittent stroke of the reciprocating guide 35. By turning this dial, the screw shaft 138 is rotated via gears 136, 137, and the screw sleeve 139 is reciprocated.

To explain in detail the operation for the cookie dough, first set the top plate 5 on the reciprocating guide 35,
After adjusting the position of the kutski dough to be squeezed out from the nozzle 4 and the front-to-back position and the vertical position relative to the top plate 5, when the motor 33 is started, the rolls 8 and 9 rotate and the kutski dough put into the dough hopper 3 is rotated. is squeezed out from the mouthpiece 4 and molded 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 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 reciprocating guide 35 is driven by an intermittent feed motor 33, and 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, before operation, adjust the adjustment parts such as the handle 55, handle 97, and dial 135 in advance, pull the reciprocating guide 35 to the frontmost position, set the top plate 5, and start it. The plate 5 receives the predetermined squeezed dough while repeating lowering, advancing, and rising intermittently, and after finishing squeezing, the top plate 5 is quickly returned to the worker's hand by a quick return operation, making it easy for one person to transfer the top plate. You can change it.

Furthermore, since the position of the ceiling 5 is accurately determined by the positioning tool 126, it is possible to overlap and squeeze out again. Also, automatic movement 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. In this case, the rotation of the roll is the opposite of that in the case of kutsky dough, so the rotation can be reversed by operating the gear 78 (FIG. 10). In the above embodiment, in the case of kutsky fabric, the gear 78 is engaged with the sprocket 77 by the geode clutches 81 and 82,
When using a water basin, the gear 78 is engaged with the gear 80.

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

〔Effect of the invention〕

The present invention provides 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 to each other; In the depositor having a transfer mechanism, the transfer mechanism includes at least a reciprocating guide that is intermittently driven by a drive device that reciprocates intermittently at a desired stroke pitch in conjunction with the rotation of the roll, and a reciprocating guide that moves the reciprocating guide by a quick return motion. The pair of rolls supported so as to be able to rotate in reverse are provided with a drive device for returning to the previous position,
Gear-shaped rolls are arranged so as to be engaged with each other, and a throttle mechanism is provided between a hopper and a hopper disposed opposite to each other on the outside of the rolls, and a geo-clutch that transmits the rotation of the rolls is provided, and the rotation direction of the drive device is controlled by the operation of the geo-yoke clutch. With this mechanism, the top plate placed on the reciprocating guide returns to the hand by a quick return movement when the squeezing process is finished, and the top plate quickly returns to the initial position of the operation, resulting in high performance. In addition, since loading and unloading of the top plate can be performed only from the front of the entire device, it can be done by one worker, which not only saves manpower, but also saves installation space and makes it more compact. In addition, the same main body can be used to easily work with kutsky fabric, water droplets, and other types of materials, greatly improving versatility, and providing a depositor that is easy and reliable for each operation. I can,
This has an extremely large practical effect.
