Description

[Detailed explanation of the idea]

[Industrial Application Field] This proposal relates to the improvement of the elbow pipe attachment part of vertical automatic packaging equipment, and is mainly used for food,
For example, it is used in a vertical automatic packaging device installed adjacent to a quantitative discharge device for foods such as potato salad.

[Prior Art] In a conventional vertical automatic packaging device, a guide tube is attached to the top plate of the device's frame so as to pass through the device in the vertical direction. The straight pipe part of the elbow pipe for use is inserted in a detachable manner, and the bent pipe part of the elbow pipe is connected to a communicating pipe that is connected to a discharge port of a quantitative discharge device installed adjacently. Further, a guide tube of a synthetic resin film for packaging is installed on the outer periphery of the lower part of the guide tube, and the film is transferred downward by a predetermined length and its bottom is heat-sealed, and the food is fed under pressure from the quantitative discharge device. After being discharged and filled from the elbow pipe, the mouth is heat-sealed, cut into pieces one by one, and finally transported out on a conveyor or the like.

[Problems that this proposal seeks to solve]

However, in the above-mentioned conventional vertical automatic packaging apparatus, as shown in FIG. The position of the upper bent pipe section is considerably higher than the elbow pipe 5' connected to the discharge port 4' of the quantitative discharge device B installed adjacently, and the communication pipe 6 connecting both elbow pipes is automatically connected. It rises at an angle toward the packaging device A.
For this reason, the discharge pressure of the quantitative discharge device B becomes high, which deviates from the specified discharge amount, and an excessive load is applied to the valve mechanism 7, which tends to cause problems such as damage to the valve. Therefore, the position of the bent pipe part of the elbow pipe of automatic packaging device A is at least horizontal with the position of the discharge port of quantitative discharge device B, or a position lower than that, as shown by the one-dot chain line in the figure. However, increasing the height of the quantitative dispensing device B by using a so-called getter will put a considerable weight on the top, making it unstable and dangerous in the event of an earthquake. It takes a lot of effort to put it in,
Personnel were needed. This is food that is inappropriate to be transported into the hopper 8 using a belt conveyor, etc.
This is a particular problem when introducing sticky foods such as potato salad. This proposal solves the above-mentioned problem, and the position of the upper bent pipe part of the elbow pipe of the automatic packaging device is made almost horizontal with the discharge port of the metering discharge device, so that the valve mechanism of the metering discharge device is overloaded. Damage to the valve mechanism is prevented without applying a heavy load, the filled food is discharged in an appropriate amount, and the elbow pipe can be removed to allow cleaning of the inside. [Structure] The elbow pipe attachment part of this proposal has a long elongated hole drilled in the upper plate of the frame in the direction of the quantitative discharge device, and the guide tube is split vertically in half from a position slightly above the sailor part of the guide tube. This guide cylinder has its half-opened surface facing the quantitative discharge device, and the flange protruding from the outer periphery of the upper end of the semicircular cylinder wall is attached to the top plate of the frame on the side opposite to the quantitative discharge device of the elongated hole. The bent pipe part of the elbow pipe fixedly fixed and the straight pipe part removably inserted into the guide tube moves up and down from the elongated hole, and when descending, the bent pipe part touches the circular cylinder wall at the half-split end of the guide tube. The gist is that it is supported by the upper edge. [Operation] When the lower cylinder wall of the bent pipe part of the elbow pipe is supported by the upper edge of the circular cylinder wall at the half-split end of the guide pipe, it is at a desirable position almost horizontal to the discharge port of the quantitative discharge device. , and the communication pipe between the two also becomes horizontal. Since the half-split end of the guide tube is located slightly above the sailor section of the guide tube, a predetermined distance can be maintained between the lower tube wall of the bent tube section and the sailor section. There is no chance of contact between the two, and it does not interfere with the packaging of the resin film. The guide tube has a flange protruding from the top outer periphery of the semicircular tube wall of the half-split portion, which is fixed to the top plate of the frame, which prevents the guide tube from wobbling and prevents the film from passing between the guide tube and the heater. The interval 〓 is also kept fixed. Note that by removing the communication tube connected to the bent portion, the elbow tube can be pulled out from the guide tube while passing the bent tube portion through the elongated hole in the upper frame plate and pulling it upward. [Example] Hereinafter, a drawing showing an example of the present invention will be specifically described. FIG. 1 is a central vertical sectional front view of the attachment part of the present invention with the elbow pipe slightly raised. The upper frame plate 1 of the vertical automatic packaging device A has a long hole 9 through which the elbow pipe 3 passes vertically. However, this long hole 9 is connected to the adjacent quantitative discharge device B (see Fig. 4).
It is lengthened in the direction of. The upper part of the guide tube 2 is vertically split from a position slightly above the sailor part 11 of the resin film guide tube 10 provided on the outer periphery of the lower part, and this half-split open surface is used for the adjacent quantitative discharge. Device B
A flange 12 that is inserted into the elongated hole 9 on the side and protrudes from the outer periphery of the upper end of the semicircular cylindrical wall is connected to the elongated hole 9 by means of an appropriate number of bolts 13, as shown in FIG. On the side opposite the device, frame top plate 1
It is tightened and fixed. In addition, this collar part 12
may be fixed by spot welding, for example. Further, 14 is a resin film for packaging, 15 is a heating heater, 16 is a film passage space, and 17 is an intermediate frame of the apparatus, and these structures are almost the same as those of the conventional apparatus. Further, the elbow pipe 3 is integrally formed with an upper curved pipe part 3a bent by approximately 90 degrees with respect to a straight pipe part having a required length. This elbow pipe 3 is constructed by inserting the straight pipe part into the guide tube 2 from above the frame upper plate 1 and lowering the bent pipe part 3a from the elongated hole 9, as shown by the dashed line in FIG. The lower cylindrical wall of the bent tube portion 3a is supported by the upper edge 2a of the circular cylindrical wall exposed at the half-split end of the guide tube 2. Note that a communication pipe 6 is connected to this bent pipe portion 3a in the same way as in the conventional case, and communicated with the discharge port 4 of the quantitative discharge device B (see FIG. 4). In this way, when the lower cylindrical wall of the bent pipe portion 3a of the elbow pipe 3 is supported by the upper edge 2a of the circular cylindrical wall at the half-split end of the guide pipe 2, it is almost the same as the discharge port 4 of the quantitative discharge device B. Since the desired horizontal position is reached and the communication pipe 6 between the two is also in a horizontal state, the discharge pressure of the quantitative discharge device does not increase, the appropriate amount of food is smoothly discharged, and no extra load is placed on the valve mechanism. is not added. Further, the half-split end of the guide tube 2 is connected to the guide tube 10.
Since the sailor section 11 is provided at a position slightly above the sailor section 11, there is a predetermined distance between the lower cylindrical wall of the bent pipe section 3a and the sailor section 11, as shown by the dashed line in FIG. Since the distance m is maintained, there will be no contact. Therefore, there is no problem in packaging the resin film 14, and even if the elbow tube 3 is accidentally dropped, the film 14 will not be damaged such as perforation. Furthermore, since the guide tube 2 has a flange 12 protruding from the outer circumference of the upper end of the semicircular tube wall of the half-split portion fixed to the frame upper plate 1, the guide tube 2 does not wobble, and the guide tube 10 and The length 16 during which the film passes between the heaters 15 is also kept fixed, and no distortion occurs. Note that by removing the communication tube 6 connected to the bent portion 3a, it is possible to pull out the elbow tube 3 from the guide tube 2 while passing the bent tube portion 3a upward through the elongated hole 9 of the frame upper plate 1. can be,
The inner surface of the elbow pipe 3 can be cleaned. [Effect] As mentioned above, according to the present invention, a long hole is provided in the upper plate of the frame, and the guide tube, which is fixed to the upper plate through the long hole, is split vertically in half from the position above the sailor part of the guide tube. Because it is shaped like this, the bent tube part can be moved up and down through this elongated hole while the elbow tube is inserted into the guide tube, and the bent tube part of the elbow tube and the discharge port of the quantitative discharge device are connected almost horizontally. This prevents excessive load from being applied to the valve mechanism of the metered dispensing device and prevents damage to it.
In addition to enabling the proper amount of food to be discharged, the elbow pipe can also be removed and cleaned. In addition, since the bent part of the elbow tube is supported above the sailor part, there is no problem with mounting and packaging the film and it will not be damaged. Since it is fixedly attached to the guide tube, there is no distortion during the passage of the film between the induction tube and the heating heater, and there is an effect that wrapping with the film can be carried out smoothly.
