Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing foods such as steamed buns and ohagi, and more particularly to an apparatus for improving the productivity by enabling continuous operation in the production thereof. .

[0002]

2. Description of the Related Art A conventional apparatus for producing food such as buns and ohagi etc. is disclosed in Japanese Patent Application No.
In the device of No. 7849, when the continuous operation is performed for a long time, the sliding portion of the frame generates heat, the plastic of the frame thermally expands, and the fitting of the sliding surface becomes tight. Problems such as burning occurred. As a device for solving the problem, there is Utility Model Registration No. 2115090 filed by the present applicant, which is characterized in that at least one side of the housing is provided with an adjusting device for adjusting a gap between the framework and the housing. It was to be. Therefore, even if thermal expansion of the frame occurs, proper adjustment of the sliding surface can be realized by adjusting the gap between the frame and the housing, and overload and seizure of the drive unit can be eliminated, and continuous operation can be performed. Could be made possible.

[0003]

However, the means for adjusting the clearance between the frame of the gap adjusting device and the housing is provided by moving the pressing plate for pressing the frame forward or backward by rotating the handle. The adjustment of the steering wheel by visual observation of the operator is required, which is very difficult. That is, when performing the steering wheel adjustment, the operator is necessarily required to make a decision on the adjustment timing and the adjustment amount. There are many decision factors in this worker's decision making, which have been made visually and empirically. For example, the adjustment time at the time of thermal expansion due to heat generation needs to comprehensively take into consideration the operation time, operation speed or smoothness of operation of the device, frictional noise, and the like. Regarding the adjustment amount for the next adjustment, the adjustment amount is empirically determined while appropriately predicting the above-described respective situations and the subsequent scheduled use. In other words, the decision making on the optimal adjustment timing and the optimal adjustment amount has so far largely depended on the skill of the device, such as the intuition of the worker and the tips, and the difference in the skill is judged. It required extremely delicate work, which resulted in differences in production efficiency and quality. Therefore, there is a demand for an adjustment mechanism that reduces such determinations without depending on the skill of the worker. As a solution, the decision of the operator is determined by various factors, so a decision making system is programmed based on the judgment factors of the skilled worker, and the optimal adjustment time and the optimal timing are adjusted by fuzzy control etc. It is also conceivable to perform the automatic adjustment by calculating the control amount, but since the device becomes complicated and large, it becomes very expensive.
An object of the present invention is to solve the above-mentioned problem by simpler means. It is a secondary object of the present invention to make it easier to use during cleaning and maintenance.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention solves the above-mentioned problem by connecting three or more rectangular sides having two adjacent sides as sliding surfaces with the sliding surfaces being in contact with each other. To form a frame, housed in a polygonal housing, the outer peripheral surface of the frame and the inner surface of the housing are used as sliding surfaces, and a central opening formed by sliding the frame is opened and closed to open and close the opening. The apparatus is configured to cut a bar-shaped material passing through the section, and to provide an adjusting device on at least one side of the housing for adjusting a clearance between the frame and the housing. In this way, even if thermal expansion of the frame occurs, appropriate adjustment of the sliding surface can be realized by adjusting the clearance of the housing in the frame. And, when the adjustment device is made to intervene with the elastic body, it is automatically adjusted by the elastic force of the elastic body even when an excessive load that needs adjustment is applied or a gap occurs. Even if a control amount that is not suitable for the optimum control amount is given, it is automatically adjusted by the elastic force.

[0005] Therefore, in a work requiring a skilled technique such as clearance adjustment, the burden of depending on the adjustment work can be reduced even by a worker with little skill, and thus a product of constant quality can always be continuously produced. . In addition, the maintenance and handling of the clearance adjustment device have been improved by attaching or detaching the elastic body with the frame incorporated in the housing. In particular, in the case of a multi-row, the number of adjustment points increases, so that the effect is very large.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) A first embodiment of the present invention will be described with reference to FIGS. As the envelope cutting device of the present embodiment, the same device as that disclosed in JP-B-63-29979 is used. A frame 2 is formed by combining a plurality of square pieces 1. In the rectangular piece 1, the sliding surfaces 101 and 102 abut against the sliding surfaces of the adjacent rectangular pieces. The frame 2 is housed in the housing 3, and the outer surface 103 of the rectangular piece 1 slides on the sliding surface 4 of the housing 3. Sliding pin 5
Is inserted into one of the rectangular pieces 1, and by sliding the rectangular piece 1 by driving means (not shown), the other rectangular pieces are also interlocked, and the opening 6 formed in the center is opened and closed to cover the bar-shaped material 18. It is to cut. An adjusting device 7 for adjusting the clearance C between the frame 2 and the housing 3 is provided at any position on the inner surface of the housing 3. Describing this adjusting device 7, the case 9 is fitted into a hole provided in the housing 3. A support member 10 is provided in the case 9, and a pressing plate 11 is attached to one end of the support member 10. The support member 10 is reciprocally slidable in contact with the case 9 and has a cylindrical hole 12.
12 is provided with a coil spring 13 which is detachably inscribed. The strength of the coil spring 13 is selected according to the material of the rectangular piece 1 and the degree of use of the device. The coil spring 13 is regulated by one end of the handle screw 15 so that the hole 12
Is maintained within. The handle screw 15 is capable of moving back and forth in the hole 12 and has a diameter large enough to press the coil spring 13, and a spiral groove 16 is provided at one end for pressing the coil spring 13 over a predetermined width. And is screwed with the spring 13. A handle screw 15 fixed to the handle 8 is screwed with the case 9 and a lock nut 17 for preventing loosening. In the embodiment, the coil spring 13 is used as the elastic body. However, the present invention is not limited to this, and a cylindrical rubber lump 19 may be used as shown in FIG. It is attached to the end face.

(Second Embodiment) A second embodiment is shown in FIG.
A description will be given based on FIGS. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. 20 is a frame 2 combining square pieces 1 and a lower conveyor belt.
21 is a wrapping and cutting apparatus provided with five at regular intervals in the width direction. The five frames 2 are respectively housed in the housing 3B so that the opening portions 6 can be opened and closed, and the two frames 2 are adjusted by an adjusting device 7B for adjusting the fit between the frame 2 and the housing 3B.
The outer surface 103 of the frame 2 is pressed from the direction.

The adjusting device 7B comprises a pressing plate 11 and its supporting member 10
B, and a pair of elastic leaf springs 22 are provided at symmetrical positions of the frame 2 at a portion that does not hinder reciprocation of a sliding pin 5 described later. Pressing plate 11 and leaf spring 22 of adjustment device 7B
Is disposed in the case 23 provided in the housing 3B, and the case
A leaf spring 22 is arranged so as to be sandwiched between 23 and the pressing plate 11, and the pressing plate 11 receives the force of the leaf spring 22 and presses the framework 2. The pressing plate 11 is a rectangular flat metal plate having a predetermined thickness, and has substantially the same size that can be accommodated in the case 23. The pressing plate 11 presses the outer surface 103 of the frame 2 and simultaneously serves as a sliding surface.
Form one side of 3B. The support member 10B is a rod-shaped piece fixed to the contact surface of the pressing plate 11 with the leaf spring 22 substantially at the center thereof, and can reciprocate in the case 9B which is a concave passage provided in the housing 3B through the leaf spring 22. It is supported detachably. The leaf spring 22 has a notch through which the support member 10B penetrates.
22B is a metal rectangular plate material provided substantially in the center,
It has a concave shape obtained by bending a predetermined width at both ends in the same direction at a predetermined angle, and the strength according to the material, shape and the like is selected by appropriately checking the degree of fitting according to the state of wear of the frame 2 and the use condition.

A drive transmission unit for opening and closing the frame 2 includes an eccentric cam 23 rotated by a drive motor (not shown), an arm 24 rotatably connected to the eccentric cam 23, and a central portion on a rotation support shaft 26. Arm 26 supporting the arm, and the arm
Rods 27 are respectively mounted on both ends of the shaft 26, and are constituted by five sliding pins 5 provided on each rod 27. Although not shown, the rod 27 is supported on its lower surface by a linear motion ball bearing unit (using an NSR type manufactured by THK) to smoothly reciprocate.

(Operation and Effect of First Embodiment) Handle 8
Is rotated, the handle screw 15 advances, and the pressing member 10 advances through the coil spring 13, so that the pressing plate 11 advances and presses the frame 2, so that the clearance C of the frame 2 can be reduced. In the frame 2, the six rectangular pieces 1 are in contact with each other, so that when the pressing plate 11 advances, when the rectangular pieces 1 that are directly in contact with the pressing plate 11 are pressed, the other rectangular pieces are also interlocked with each other. Since the clearance is reduced, the play of each square piece 1 is reduced. When the handle 8 is rotated in the reverse direction, the pressing plate 11 is
Are recessed, the clearance increases, and the fitting with the housing 3 is loosened. Since the coil spring 13 is interposed between the support member 10 and the handle screw 15, the fitting of the frame 2 is transmitted to the handle 8 via the coil spring 13, so that the operator can judge the optimum amount intuitively. In addition, the judgment is not quantitative and there are individual differences.However, even when a slight excessive pressing force is applied or when the pressing force is slightly insufficient, the elastic force of the coil spring 13 makes it impossible. A strong force or the like is absorbed or reinforced, and as a result, the pressing force of the pressing plate 11 acts in an optimal direction. Therefore, the adjustment work can be easily performed without requiring much experience.
In the past, it was necessary to frequently perform the adjustment work, for example, during the thermal expansion process of the rectangular piece 1 during operation, or during exhibition and sales where the operation time and the negative operation time were performed in a fixed cycle, Even in the case of production, if the adjustment is within the range that can depend on the elastic force of the coil spring 13, the pressing force is automatically supplemented, so it can be performed without the need for adjustment. We were able to.

In the present embodiment, the diameter of the handle screw 15 is made substantially the same as or larger than the diameter of the coil spring 13, and a spiral groove 16 is provided at one end thereof so as to be screwed with the coil spring 13. Since the handle screw 15 and the coil spring 13 are integrally removed from the case 9 and can be freely inserted, replacement of the coil spring 13 and attachment of the frame 2 at the time of cleaning and the like have become very easy. That is, when the coil spring 13 cannot be pulled out in the direction of the handle 8, the support member 10 is always receiving a force by the coil spring 13, and
When the frame 2 is removed from the housing for cleaning, the pressing plate 11 is pushed out by the coil spring 13 as soon as the frame 2 is removed, or conversely, when assembled, the frame 2 is attached to the housing 3 while receiving the force of the spring 13. Since it has to be inserted, it involves very complicated work. Therefore, Framework 2
Since the coil spring 13 can be attached or replaced while the coil spring 13 is in the housing 3, the working efficiency can be further improved. Further, since the support member 10 is inwardly slidable in contact with the case 9, even if the pressing member 11 receives a pressing force from the square piece 1 near the end of the pressing plate 11, for example,
This prevents the 11 from tilting and enables stable opening and closing of the framework 2.

(Effects of Second Embodiment) Eccentric cam 23
Each of the rods fitted into the frame 2 by the reciprocating swing of the connecting arm 26 pivotally supported at the center by the reciprocating swing of the connecting arm 26 via the arm 24 by reciprocating linear movement. Drive is transmitted to 27. Therefore, the frame 2 repeats the opening and closing operations in the housing 3B in synchronization with the reciprocating motion of each rod 27, and cuts the bar-shaped food dough passing through the opening 6. At this time, since two sides of the frame 2 are pressed by the adjusting device 7B incorporating the leaf spring 22, a gap is generated due to abrasion of the frame 2 which repeats the opening and closing operation, or the frame 2 is fitted even if expanded by frictional heat. Is maintained in an optimal state, and the frame 2 is opened and closed without difficulty, thereby enabling stable cutting of the envelope. still,
The support member 10B is a case that is a concave passage of the housing 3B.
Since the side of the frame 9B is forcibly regulated so as to be capable of reciprocating sliding, the opening and closing operation of the frame 2 can be stably performed without the pressing plate 11 being inclined.

In particular, the five columns shown in the present embodiment
In a large-sized device provided with, a worker cannot adjust the fitting of the frame 2 during operation of the machine due to hygiene and safety, but leaf springs are incorporated on two opposite sides of each frame 2. As a result, the pressing effect of the elastic body is increased, and the operation can be performed for a long time without stopping the operation of the machine. Also, in the case of multi-row, if the adjustment for each location is performed by the operator's judgment as in the conventional case, it takes a very long time to perform the adjustment. However, the apparatus according to the present embodiment requires one cycle of operation. The amount of production and production time can be determined systematically because the adjustment in the process can be eliminated or greatly reduced.
It has a very large effect that enables efficient use of machines and stable production. Was. In this embodiment, the rectangular piece shown in FIG. 4 has been described. However, the present invention is not limited to this, and any rectangular piece that slides in the housing may be used. A half-opening method and apparatus for intentionally opening one cut surface without performing complete wrapping as shown in JP-A-5-317019 may be used.

[0014]

As described above, the present invention solves the problems of the conventional gap adjusting device of the wrapping and cutting device, and the gap adjusting operation which has been performed so far by using an elastic body in the gap adjusting mechanism. In addition, since the frequency of the adjustment can be reduced and the adjustment operation can be performed without requiring a skilled technique, the product can be maintained at the same quality even after a long continuous operation. Therefore, with a very simple device, it is possible to greatly reduce the burden on the device and the burden on the operator in continuous production for a long time.
