Description

  The present invention relates to a kneaded food cutting machine for quantitatively cutting kneaded foods such as koji, tsukune, and konjac extruded from an extrusion nozzle.

A large bowl (one bowl of pestle) sown with a mortar or pestle is divided into a certain size and rounded by hand to make a small bowl. Dividing is surprisingly difficult and requires a lot of effort. Therefore, manual scissors are commercially available for home use and electric scissors for business use.
Household scissors cutting machine is a hopper that stores freshly speared large scissors, a manual extrusion mechanism (extrusion cylinder and extrusion screw) that is installed at the bottom of the hopper and pushes the scissors horizontally, and the tip of the extrusion cylinder Equipped with an extrusion nozzle installed in the hand and a manual cutting blade for cutting off the rivet extruded from the opening of the extrusion nozzle. The extrusion screw is rotated by the handle to push out the crease from the tip of the extrusion nozzle and cut with the cutting blade. .

  The commercial scissors cutting machine has the same structure as that for household use (see Patent Document 1), but the extrusion screw and cutting blade are electric, and an electric rotary table is installed below the extrusion nozzle. The rotation of the extrusion screw and the operation timing of the cutting blade are variable, and the rod that is continuously pushed out from the tip of the extrusion nozzle is cut with a cutting blade that automatically operates at a predetermined timing, and the rotation rotates continuously. It is dropped on a table (turntable) and is rotated and conveyed to the next process (for example, an operator who rolls up a basket).

Japanese Patent No. 3126095

In the case of the above-mentioned household scissors cutting machine, since both the operation of the extrusion screw and the cutting blade is performed manually, it is difficult to link the scissor extrusion and cutting work, and the size of the scissors cut varies, In the middle of cutting, wrinkles leaking from between the tip of the nozzle and the cutting blade may become entangled with the cutting blade and cause a failure. Also, work efficiency is poor.
On the other hand, in the case of an electric scissor cutting machine, the cutting operation is fully automatic and the work efficiency is good. Therefore, in order to keep the size of the cut wrinkles constant by changing the amount of extrusion, it is necessary to frequently adjust the number of rotations of the screw and the timing of cutting, which easily leads to loss of work time and waste of wrinkles. Further, since the wrinkles are continuously extruded during cutting, the wrinkles may be clogged between the cutting blade being cut and the extrusion nozzle, which causes a failure. In addition, because the turntable rotates continuously, the fallen kite rolls off the fixed position and interferes with the next work, falls off the table, sticks to the kite that has fallen first, or extends long. It may collapse.

  The present invention has been made in view of the problems of such a conventional scissor cutting machine, and it is easy to keep the size of the scissors cut constant without making troublesome adjustments. It is an object of the present invention to provide a scissor cutting machine that can prevent clogging between a blade and an extrusion nozzle or prevent a dropped crust from rolling on a table.

  The present invention includes a hopper for storing the kneaded food before cutting, an extrusion mechanism that is installed at the bottom of the hopper to push the kneaded food forward, a motor that drives the extrusion mechanism, and a front end of the extrusion mechanism. An installed extrusion nozzle, a cutting blade that moves along the opening of the extrusion nozzle and cuts off the crushed food extruded from the opening, and is installed below the extrusion nozzle and cut off by the cutting blade In a kneaded food cutting machine provided with a turntable for receiving the kneaded food and a motor for driving the turntable, a control means is provided for associating the movement of the cutting blade with the on / off of the two motors. When the cutting blade moves from the initial position before cutting, both motors are turned off, and when the cutting blade returns to the initial position after cutting, both motors are turned on. The features. In addition to the koji, the kneaded food referred to in the present invention includes kneaded foods that can be treated in the same manner as koji, such as so-called kneaded foods, tsukune, and konjac.

  According to the cutting machine according to the present invention, it is easy to keep the size of the kneaded food such as the cut rice cake without making troublesome adjustment. In addition, it is possible to prevent the kneaded food from being clogged between the cutting blade and the extrusion nozzle during cutting, or the dropped kneaded food from rolling on the table.

It is a front view (partial cross section) of the scissors cutting machine according to the present invention. FIG. 3 is a plan view (partially omitted). It is a side view of the cutting blade vicinity, (a) shows a state when the cutting blade is in a standby state at the initial position, and (b) shows a state when it is moved to the cutting position. It is a block diagram of the control means which relates the movement of a cutting blade, and on-off of the said both motors.

Hereinafter, with reference to FIGS. 1-4, the kneaded food cutting machine (especially rice cake cutting machine) which concerns on this invention is demonstrated concretely.
This scissor cutting machine includes an extruding unit 2 and a transfer unit 3 installed on a machine base 1, and a cutting unit 4 provided alongside the extruding unit 2.

  The extrusion unit 2 includes a support unit 5 fixed to the machine base 1, an extrusion cylinder 6 installed horizontally on the support unit 5, an extrusion screw 7 rotatably supported in the extrusion cylinder 6, and an extrusion cylinder An extrusion nozzle 8 that is fixed to the front end of 6 and has an inner diameter that gradually decreases toward the opening (front end), a hopper 9 that is installed at the top of the extrusion cylinder 6, and a motor that is connected to the rear end of the extrusion screw 7. 11 and a display device 12 that counts and displays the drive amount (rotation speed) of the motor 11.

The hopper 9 includes a lower hopper 13 integrated with the extrusion cylinder 6 and an upper hopper 14 installed thereon. The upper part of the extrusion cylinder 6 is open, the lower end of the lower hopper 13 communicates with the opening 15, and the soot introduced into the hopper 9 is fed into the extrusion cylinder 6 through the opening 15. When the motor 11 is rotated, the extrusion screw 7 is rotated, and the ridges in the extrusion cylinder 6 are fed forward and pushed forward from the opening of the extrusion nozzle 8. The extrusion cylinder 6 and the extrusion screw 7 constitute the extrusion mechanism referred to in the present invention.
The display device 12 includes a control unit 16 and a display unit 17. The control unit 16 counts the number of rotations of the motor 11 (the number of rotations of the extrusion screw 7), displays the count number on the display unit 17, and detects the movement when a cutting blade 19 described later is moved from the initial position. Thus, the count number is automatically reset and the display is returned to the initial value (zero).

The cutting part 4 is fixed to the bracket 18 integrally formed with the extrusion nozzle 8, a cutting blade 19 supported at one end by a pin (not shown) fixed to the bracket 18, and swingable. It consists of a limit switch 21. A handle portion 22 is formed at the other end of the cutting blade 19 for manually swinging. The cutting blade 19 is moved along the end surface 23 of the bracket 16 (functioning as a guide surface of the cutting blade 19; see FIG. 3) by grasping the handle portion 22, and the cutting blade 19 is moved along the outer surface of the opening of the extrusion nozzle 8. Further, it is possible to swing (reciprocate) between the initial position (FIG. 3A) and the cutting position (FIG. 3B). At this time, the cutting blade 24 of the cutting blade 19 crosses the opening 25 of the extrusion nozzle 8 and cuts the extruded ridge.
The cutting blade 19 is always urged toward the initial position by a coil spring (not shown), and is in contact with the limit switch 21 at the initial position by the urging force.

  The transfer unit 3 includes a bracket 26 fixed to the machine base 1, a motor 27 fixed to the lower surface of the bracket 26, and a rotation that is fixed to the upper end of the rotation shaft of the motor 27 and rotates through a position below the extrusion nozzle 8. It comprises a table 28 and a ball support 29 that is located directly below the opening of the extrusion nozzle 8 and is installed under the rotating table 28. The ball support 29 includes a ball 31 and a casing portion 32 that rotatably supports the ball 31. The casing portion 32 is fixed to the upper surface of the bracket 26, and a part of the ball 31 protrudes upward from the casing portion 32 to rotate. It contacts the lower surface of the base 28. The turntable 28 receives the cut and dropped wrinkles, and rotates by the motor 27 to convey the wrinkles in the circumferential direction. The conveyed wrinkles are picked up manually and rounded into small wrinkles. The ball support 29 has a function of receiving the impact of the dropped kite.

  As shown in FIG. 4, the limit switch 21 controls on / off of the motor 11 that rotates the extrusion screw 7 and the motor 27 that rotates the turntable 28. More specifically, when the cutting blade 19 comes to the initial position with the power switch turned on (at the same time as returning to the initial position), the cutting blade 19 is connected to the limit switch 21 as shown in FIG. When the electric power of the motors 11 and 27 comes into contact and the cutting blade 19 leaves the initial position (at the same time as starting to move toward the cutting position), as shown in FIG. The power of the motors 11 and 27 is turned off away from the limit switch 21. In this example, the limit switch 21 constitutes the control means referred to in the present invention, and the cutting blade 19 functions as the operating body.

Next, how to use this scissors cutting machine will be described.
First, for example, a freshly crushed scissors (the scissors before cutting) are put into the hopper 9, for example, and a power switch (see FIG. 4) is turned on with the cutting blade 19 stopped at the initial position. Rotates, the extrusion screw 7 rotates, and the ridge is pushed out from the tip of the extrusion nozzle 8. At the same time, the rotation number of the motor 11 is counted, and the count number is displayed on the display unit 17 of the display device 12.

  When the operator visually confirms that a predetermined amount of the ridge has been pushed out, the operator moves the cutting blade 19 from the initial position toward the cutting position, and cuts the pushed out ridge at the opening of the extrusion nozzle 8. Simultaneously with the movement of the cutting blade 19 from the initial position, the power of the motors 11 and 27 is turned off by the action of the limit switch 18, and the rotation of the extrusion screw 7 and the turntable 28 is stopped. A predetermined amount of the cut soot falls on the turntable 28 and is placed on the turntable 28 immediately below the opening of the extrusion nozzle 8. Moreover, the count number of the display part 17 is reset with the movement of the cutting blade 19. As described above, the cutting of the scissors by the cutting blade 19 and the dropping of the cut scissors onto the turntable 28 is performed in a state where the rotation of the extrusion screw 7 and the turntable 28 is stopped.

Subsequently, the cutting blade 19 is moved back from the cutting position toward the initial position. At the same time when the cutting blade 19 returns to the initial position, the electric power of the motors 11 and 27 is turned on by the action of the limit switch 18, the extrusion screw 7 and the turntable 28 start to rotate, and the number of rotations of the motor 11 is counted simultaneously. The count number is displayed on the display unit 17 of the display device 12. Thereafter, the worker may repeat the same work.
If the amount of extrusion of the ridge is stable with respect to the number of revolutions of the motor 11 (steady state), the cutting blade 19 is moved each time the count reaches a certain value without directly checking the amount of ridge extrusion. By operating it, the extruded ridges can be cut into the same size.

  With this scissor cutting machine, the scissors are cut after the operator confirms that a predetermined amount of scissors has been pushed out, so the size of the cut scissors is constant even at the beginning of work when the amount of sputum extrusion is not stable. Can be kept in. In addition, even when the hardness of the heel changes in the initial stage and the late stage of the work and the amount of heel extrusion per unit revolution of the motor 11 changes, the operator confirms the amount of extrusion and cuts. The size of the cocoon can be kept constant. Furthermore, if the extrusion amount of the wrinkles is a steady state, the size of the cut wrinkles can be kept constant only by checking the count number. On the other hand, it is possible to change the size of the wrinkles along the way.

In this scissor cutting machine, scissors cutting by the cutting blade 19 is performed while the extrusion screw 7 is stopped (stopping the extrusion), so that it is easy to cut, and between the cutting blade 19 being cut and the opening of the extrusion nozzle 8. It is also possible to prevent the wrinkles from being pushed out and clogged, and the wrinkles from being entangled with the cutting blade 19. Further, when returning the cutting blade 19 that has reached the cutting position toward the initial position, since the wrinkles are not pushed out from the opening of the extrusion nozzle 8, the wrinkles are not entangled with the cutting blade 19 and are easily returned.
Further, since the cut scissors fall on the stopped rotating table 28, the scissors are dropped and placed at a predetermined position on the rotating table 28, and do not roll or lose shape on the table.

This scissor cutting machine can be modified as follows, for example.
(1) In the above example, the limit switch 21 with which the cutting blade 19 contacts at the initial position is provided as the control means. However, another detection sensor is installed instead of the limit switch so that the cutting blade 19 is at the initial position. It is also possible to detect whether or not there is. For example, a non-contact proximity sensor such as a reflective photoelectric sensor or a magnetic sensor is convenient.
(2) In the above example, the operator confirmed the extrusion amount of the rod or visually confirmed the displayed count number and moved the cutting blade 19, but the count number was a specified value (of a predetermined size). It is convenient to add to the display device 12 a function for automatically notifying when the number of counts to be pushed out is reached. As the notification means, for example, transmission of signal sound or signal light can be considered. In this case, it is desirable that the specified value can be arbitrarily set in the display device 12 according to the target size of the gavel.

(3) In the above example, a limit switch is installed as an on / off control means for the motors 11 and 27, and the movement of the cutting blade 19 by the operator and the on / off of the motors 11 and 27 are related. When the number reaches a specified value, the motors 11 and 27 are automatically turned off. Subsequently, when the operator moves the cutting blade 19 to cut the scissors, and further returns the cutting blade 19 to the initial position, the motor 11 , 27 can be automatically turned on.
(4) In the case of (3) above, instead of the operator moving the cutting blade 19, a moving means for reciprocating the cutting blade 19 is provided, and the motors 11 and 27 are automatically activated when the count number reaches a specified value. Alternatively, the moving means may be automatically operated while being turned off. Alternatively, when the count number reaches a specified value, for example, an activation button may be pressed to activate the moving means.

(5) The structure of this koji cutting machine can be used as a kneaded food cutting machine that can be processed in the same way as koji, such as kneaded foods, tsukune, and konjac, in addition to koji.
The configurations (3) and (4) described above are used for cutting a kneaded food product in which the amount of extrusion is kept substantially constant during the cutting operation (the variation in the amount of extrusion per unit revolution of the extrusion screw is small). Suitable.
