Description

  The present invention is a film used when extruding a sealing material or the like as a content from a film pack formed by packing a material having high tackiness mainly used in construction or the like, for example, a sealing material or an adhesive with a film. The present invention relates to a pack extrusion mechanism and a method for extruding film pack contents.

  Conventionally, as an extrusion gun 10a used for extruding a sealing material or the like from a film pack, as shown in FIG. 52, an extrusion rod 28 having a pressing plate 42 at the tip, and the extrusion rod 28 is manually operated by a lever 22 or the like. A main body part 14 to be moved forward by a type (or an electric type), a cylindrical cylinder 16a detachably attached to the front of the main body part 14, and a nozzle attachment cap 96 at the tip of the cylinder 16a. The film pack housed in the cylinder 16a is pushed forward by the push rod 28 and pressed by the pressing plate 42 so that the sealing material in the film pack is discharged from the nozzle 98. Those are known (for example, Patent Document 1, Patent Document 2 and the like).

  This conventional extrusion gun 10a for a film pack is used as follows. First, the nozzle 98 is removed from the cylinder 16a, the film rod is inserted into the cylinder 16a from the tip of the cylinder 16a in a state where the push rod 28 is pulled rearward, and the tip of the film pack is opened with scissors or the like. By attaching the nozzle 98 to the cylinder 16a, the setting of the film pack to the extrusion gun 10a is completed.

  The push rod 28 is advanced by operating the lever 22 of the main body 24, and the sealing material is pressed together with the film pack by the pressing plate 42 attached to the tip of the push rod 28. The sealing material in the film pack Etc. are discharged from the nozzle 98.

  Since this extrusion gun 10a is provided with a cylindrical cylinder 16a, there is a disadvantage that the cost is increased as compared with a case where a holding stand described later is installed. In the extrusion gun 10a, when the extrusion rod 28 is advanced and the film pack is pressed by the pressing plate 42, the film of the film pack is sandwiched between the inner wall of the cylinder 16a and the outer peripheral surface of the pressing plate 42. If the film is bitten in this way, there is a disadvantage that the extrusion of the extrusion rod 28 becomes heavy and does not go smoothly (see Patent Document 3 and Patent Document 4).

  The push-out mechanism of the push-out rod 28 in the push-out gun 10a is the same as that of the push-out gun 10 to be described later, and the detailed description thereof is omitted.

  As means for accommodating the sealing material, adhesive, etc., a hard cartridge container is used in addition to the above-described soft film pack. As shown in FIG. 53, the cartridge container 100 is formed by integrally forming a cylindrical container body 104 having a piston 102 slidable therein and a discharge nozzle 106, and is an extrusion rod of the extrusion gun 10. The piston 102 is pushed forward by the advance 28, and the sealing material C such as the internal sealing material is discharged from the discharge nozzle 106. The extrusion gun 10 used to extrude the sealing material C in the cartridge container 100 is an essential member for the cylindrical cylinder 16a to accommodate the film pack in the above-described extrusion gun 10a for a film pack. In contrast, since the sealing material or the like is already accommodated in the hard cartridge container 100, the cylindrical cylinder 16a is not necessary. Instead, a semi-cylindrical holding table 16 may be installed. Accordingly, the manufacture of the extrusion gun 10 has the advantage that it is easier and the cost is lower than the manufacture of the extrusion gun 10a.

  However, as a matter of course, the extrusion gun 10 for the cartridge container 100 cannot be used as an extrusion gun for a film pack, and the extrusion gun 10a for a film pack and the extrusion gun 10 for a cartridge container are separately provided. Currently, it is manufactured and used.

  For example, even when an extrusion gun for a cartridge container has already been purchased and used, when a film pack-like sealing material or the like is used, it is necessary to purchase a new extrusion gun for a film pack.

  Further, when both a cartridge container and a film bag are used at a site where a sealing material or the like is used, only one type of extrusion gun is sufficient, and both the cartridge container extrusion gun 10 and the film pack extrusion gun 10a are brought. There was a need to do.

  On the other hand, if the cartridge container 100 moves the piston 102 from one end to the other end, and discharges and uses up all of the sealing material inside, the empty container is discarded as it is. When the film pack is also pressed and all the sealing material inside is discharged, it is crushed and discarded.

  When film packs and cartridge containers are compared, film packs are less expensive than cartridge containers in terms of manufacturing costs, and cartridge containers are bulky when discarded, whereas film packs are crushed and become less bulky. Therefore, there is an advantage that it is convenient for transportation and processing. Although the environmental impact caused by waste contamination currently disposed of around the world has become a problem, the amount of discarded film packs is much smaller than that of cartridge containers, which is also preferable in this respect.

  As described above, the film pack is less expensive and has less problems with disposal, but the problem is that a special extrusion gun is required for extrusion discharge of the contents.

  In view of the above circumstances, the applicant of the present application is able to efficiently use a film pack by using an extrusion gun for a normal cartridge container instead of a special extrusion gun, and the contents of the film pack extrusion mechanism A method for extruding a product has already been proposed (Japanese Patent Laid-Open No. 9-314012).

  In the above proposal, there is still room for improvement regarding the removal and disposal mechanism of the crushed used film pack and the attachment / detachment mechanism of the cylinder body containing the film pack to the holding base of the extrusion gun. The inventor of the present application has further studied these mechanisms and made a new proposal for an improved mechanism.

  On the other hand, as shown in FIG. 54, (a) the holding table 16, the fixed holding plate 46 provided at the front end of the holding table 16, the pressing plate 42 provided at the tip, and advancement on the holding table 16. An extruding gun 10 having an extruding rod which can be retracted; and (b) a cylinder body 82 which can be set on the holding table 16 and can accommodate the film pack F therein and which is open at both ends; A cylindrical member 11 having a piston body 83 that is slidably inserted therein, and (c) a front end portion serving as a discharge port 106a, a through discharge passage 108 for contents C provided therein, and a rear end portion described above. There is also known a film pack extrusion mechanism that includes a nozzle body 106 that can be detachably contacted with a front end opening of the cylinder body 82 and is detachably attached to the fixed holding plate 46.

  In this case, first, the cylindrical member 11 in which the piston body 83 is slidably inserted into the rear end opening of the cylinder body 82 is prepared. With the rear end of the cylinder body 82 placed on the holding table 16 of the extrusion gun 10, the film pack F is accommodated in the cylinder body 82 from the front end opening of the cylinder body 83, and the front end portion of the film pack F Is cut with scissors etc. and opened. At the time of opening, the crimped portion K at the tip that is crimped using a crimping member such as an aluminum wire is usually left attached to the tip for the purpose of preventing the generation of dust.

  As shown in FIG. 54, the caulking portion K that remains attached to the tip of the film pack F narrows or closes the flow path of the through-discharge passage 108 of the nozzle body 106 in the process of crushing the film pack. In other words, the contents leak from the cylindrical member 11 and cause inconvenience.

  In consideration of the above-described circumstances, the applicant of the present application has prevented a constriction or blockage of the flow path of the through-discharge passage by the caulking portion of the film pack, thereby avoiding inconvenience such as occurrence of liquid leakage of contents. A proposal for an extrusion mechanism was made (Japanese Patent Application No. 9-322826).

  In the conventional film pack extrusion mechanism, when the cylindrical member is set on the holding base of the extrusion gun, the cylindrical member is in contact with the inner surface of the head adapter fixed to the fixed holding plate. It is necessary to be mounted on. Usually, a contact member such as an annular flange is provided on the inner surface of the head adapter in order to satisfactorily insert the cylindrical member. When such an annular flange or the like exists, it is necessary to insert it into a contact member such as an annular flange from a state that is as parallel as possible to the holding base and is separated from the contact member such as the annular flange. there were. For this reason, it is troublesome to insert the cylindrical member into the abutting member such as an annular flange as long as possible, and the length of the holding portion of the push-out gun needs to be set considerably longer than the length of the cylindrical member. There is a disadvantage that the material cost is high and the handling is inconvenient.

  Further, in consideration of such circumstances, the applicant of the present application inserts and holds the tubular member on the inner surface of the head adapter by configuring the inner surface of the head adapter so as to face obliquely upward. The cylindrical member can be set very easily on the base and the length of the holding base can be made close to the length of the cylindrical member, saving material costs and making the entire extrusion gun A proposal was made for a novel film pack extrusion mechanism that can be easily manufactured because it can be manufactured in a short length (Japanese Patent Application No. 10-23258).

The applicant of the present application has continued various studies and studies for the above-mentioned proposed patent application with the aim of improving its performance and made further proposals (Japanese Patent Application No. 10-204921). This time, the above-mentioned three patent applications are put together and new improvements are added to reach a proposal as one patent application.
JP-A-4-279458 JP-A-5-301064 JP-A-4-271864 JP-A-4-271865

  A first object of the present invention is to allow a sealing material or the like from a film pack to be extruded and discharged using an extrusion gun for a cartridge container. If there is an extrusion gun for a cartridge container, an extrusion gun for a film pack is provided. It is not necessary to purchase and use separately, and the cylindrical member consisting of the cylinder body and piston body can be used continuously, and only the used film pack needs to be discarded as in the case of the extrusion gun for the film pack. Even after the pack contents are pushed out, only the nozzle body is soiled and the inner surface of the head adapter is not soiled, and only the dirty nozzle body is discarded after a predetermined number of extrusion operations. Waste that can be used over and over again and is a source of toxic gas such as dioxin when incinerated Reduces, it is to provide an extrusion method help to become film pack for extruding mechanism and contents of the film pack solving environmental problems.

  The second object of the present invention is to insert the tubular member into the inner surface of the head adapter and to attach the tubular member to the holding base, in particular, by configuring the inner surface of the head adapter so as to face obliquely upward. Setting can be performed very easily and the length of the holding base can be made close to the length of the cylindrical member, so that material costs can be saved and the entire extrusion gun can be manufactured in a short length. Therefore, it can be handled easily, and the film pack can be effectively prevented from being bitten, and the film pack can be used efficiently, and the through discharge passage by the caulking portion of the film pack. Taking out the used film pack that has been crushed and preventing inconveniences such as liquid leakage of contents by preventing narrowing and blockage of the flow path It is to provide an extrusion method of the film pack for extruding mechanism and contents of the film pack to be able to make fine waste work easily.

  In order to solve the above problems, an extrusion mechanism for a film pack according to the present invention is an extrusion mechanism for discharging contents contained in a film pack, and (a) a holding table and a front end portion of the holding table A fixed holding plate provided with a notch having an upper portion opened at a central portion thereof, an extrusion gun having a push plate provided at a tip and capable of moving forward and backward on the holding table; and (b) the A cylinder having a cylinder body that can be set on a holding stand, can accommodate a film pack therein, and has both ends open, and a piston body that is slidably inserted into the cylinder body and that has both end surfaces as pressing surfaces. A head having a member, and (c) a substrate having an outer surface located on the inner surface side of the fixed holding plate and capable of abutting the opening end of the cylinder body on the inner surface and having an opening at the center thereof An adapter (d The tip and the discharge port, inside a through discharge passage of the contents, but in which the said through discharge passage and the cylinder body comprising a nozzle body mounted to the opening of the head adapter so as to communicate.

  The above-described head adapter is preferably attached to the both edge portions of the notch portion of the fixed holding plate via appropriate engaging means, but without using such engaging means, the head adapter substrate can be used. Needless to say, even if it is merely positioned on the inner surface side of the fixed holding plate, it can be applied as long as it does not hinder the function of receiving the cylinder body of the cylindrical member.

  If the nozzle body has a structure that can be detachably attached to the head adapter, each nozzle body can be treated as a separate body.

  If the head adapter is configured to be attached to both edge portions of the notch portion of the fixed holding plate that is rotatable in the vertical direction and formed so that the inner surface of the substrate can face obliquely upward, There is an advantage that the cylindrical member can be inserted into the holder and the cylindrical member can be set on the holding base very easily.

  A base outer surface portion of the nozzle body has a shape corresponding to an inner shape of the head adapter, and the nozzle body is inserted from the inside of the head adapter into an opening of the head adapter and the inner surface of the head adapter and the nozzle If the nozzle body is attached to the head adapter by matching the base outer surface portion of the body, the inner surface of the nozzle body fitted on the inner surface side of the head adapter even when the contents are discharged However, since the inner surface side of the head adapter is completely covered with the nozzle body, it is not contaminated by the contents.

  For this reason, the nozzle body is discarded after an appropriate number of ejection operations, but the head adapter is not dirty at all, so it is only necessary to discard the nozzle body, and the same head adapter can be used repeatedly. The quantity can be reduced, which helps to solve environmental problems.

  As the head adapter, a step portion formed on the outer surface side of the substrate by projecting outward from the central portion of the substrate so as to be able to be inserted into the cutout portion of the fixed holding plate, and the inside of the step portion A step space that is formed integrally with the opening, and the outer opening is opened at the tip of the step, so that it remains at the tip when the film pack is opened. Since there is room to accommodate the metal caulking portion, the through hole and the through discharge passage are not blocked.

  The head adapter further includes a nozzle body mounting portion that protrudes from the outer surface side of the substrate and has a through hole that communicates with the opening. The nozzle body includes the nozzle body mounting portion. It is preferable that the head adapter be attached to the head adapter.

  The head adapter protrudes outward from the center portion of the previous substrate so that the notch portion of the fixed holding plate can be inserted, and the step portion formed on the outer surface side of the substrate and the step adapter inside the step portion A step space formed integrally with the opening, the nozzle body mounting portion projects from the tip of the step portion, and the step space communicates with the through hole. If the space is formed larger than the through-hole, there is room to accommodate the metal caulking portion remaining at the tip when the film pack is opened, so that the through-hole and the through-discharge passage are not closed.

  The head adapter has an engaging member which is provided at the upper end portion of the substrate so as to be rotatable by hinge means or the like and is engageable with both edge portions of the notch portion of the fixed holding plate. When the head adapter is attached to the fixed holding plate in a state of being engaged with both edge portions, a configuration in which the inner surface of the substrate can turn so as to face obliquely upward can be employed.

  The head adapter is attached to the upper end portion of the substrate and bent outward, and the both ends of the notch portion of the fixed holding plate provided at both ends of the tip of the bending spring piece And when the head adapter is attached to the fixed holding plate in a state in which the engaging member is engaged with both edges of the notch, the bent spring piece It is preferable that the substrate is always urged so that the inner surface of the substrate faces obliquely upward by the spring action.

  If the head adapter has an annular flange that is formed on the inner surface side of the substrate and can be inserted into the opening end of the cylinder body, the cylinder adapter can be inserted into the opening end of the cylinder body. It becomes easy.

  If the wall surface connecting the annular flange and the step space is formed on the slope, and if a dome-shaped receiving slope for making the circular portion at the tip of the film pack easy to receive is formed, the film pack The front end of the film is smoothly received by the receiving slope, so that the film pack can be pushed out more smoothly.

  If a configuration is provided in which a large number of protrusions are provided in the longitudinal direction of the inner peripheral surface of the cylinder body and a plurality of concave grooves are provided corresponding to the protrusions in the sliding direction of the outer peripheral surface of the piston body, Biting of the film pack between the inner peripheral surface and the outer peripheral surface of the piston body is more effectively prevented.

  If projecting stoppers are provided in the vicinity of both ends of the inner peripheral surface of the cylinder body, when the piston body is slidably inserted into the inner peripheral surface of the cylinder body, the piston body There is an advantage that it does not fall off easily from the body.

  If both end portions of the inner peripheral surface of the cylinder body are made flat, there is an advantage that the inserting operation when the piston body is inserted into the inner peripheral surface of the cylinder body is facilitated.

  When the piston body comprises a disc having a hole in the center and an annular rim provided on the outer peripheral surface of the disc, the film is formed when the base end portion of the film pack is pressed by the piston body. The caulking portion of the base end portion of the pack is located in the hole so as not to obstruct the pressing operation by the piston body.

  In addition to making the nozzle body and the head adapter separately detachable, it is also possible to adopt a structure in which both are integrally attached.

  The film pack extrusion method of the present invention is a method of extruding the contents of the film pack by the film pack extrusion mechanism described above, and the piston body is positioned at the rear end opening of the cylinder body of the cylindrical member. A film pack having a front end opened from the front end opening is accommodated inside the cylinder body, an extrusion gun having a head adapter positioned on the inner surface side of the fixed holding plate is prepared, and then a cylindrical member containing the film pack The cylindrical member is set on the holding base of the extrusion gun with the tip of the substrate being brought into contact with the inner surface of the substrate, and the piston body is advanced by advancing the extrusion rod. The nozzle body is discharged, the piston body reaches the front end opening of the cylinder body, the film pack is crushed, and the entire contents are discharged. After discarding the used film pack that has been pressed and pressed against the head adapter, the cylindrical member that has been emptied is reversed and its front end and rear end are replaced, and a piston is inserted into the rear end opening of the cylinder body. When the body is placed in a start-up state, a new film pack with the front end opened from the front end opening is stored in the cylinder body, the cylindrical member is set again on the extrusion gun, and the above-described extrusion procedure is repeated. The contents of a new film pack can be extruded, and the contents of a plurality of film packs can be extruded one after another by the same cylindrical member.

  When a nozzle body having a structure that is detachably inserted into the opening of the head adapter is used, the nozzle body is soiled by the contents after the above extrusion procedure is repeated by the same cylindrical member. Is a clean state, and only the dirty nozzle body after use is discarded, and a new nozzle body is reattached to a clean head adapter so that the extrusion procedure described above is performed. Since there is no need to dispose of the head adapter and the head adapter is also discarded, the amount of waste that becomes a source of toxic gas such as dioxin at the time of incineration of garbage can be greatly reduced.

  As the film pack used in the film pack extrusion mechanism described above, a film pack having a structure in which the contents are sealed and filled by filling the contents into a cylindrical film body and caulking both ends with caulking members is preferably used.

  According to the present invention, it is possible to extrude and discharge a sealing material or the like from a film pack using an extrusion gun for a cartridge, and therefore, an extrusion gun for a cartridge container can also be used as a film pack. It is no longer necessary to purchase and use a specially structured film pack extrusion gun, and it is possible to use a cylindrical member consisting of a cylinder body and piston body continuously, which is the same as in the case of a conventional film pack extrusion gun. The effect that only the used film pack needs to be discarded is achieved.

  Furthermore, according to the present invention, if the configuration in which the nozzle body is detachably attached to the inner surface side of the head adapter is adopted, only the nozzle body is soiled even after the contents of the film pack are extruded, and the inner surface of the head adapter is soiled. Dispose of only the dirty nozzle body after a predetermined number of extrusion operations, and allow the head adapter without dirt to be used over and over again. A significant effect is achieved that reduces the amount of waste that is the source of generation and helps solve environmental problems.

  In addition, according to the present invention, it is possible to insert the tubular member on the inner surface of the head adapter and to set the tubular member on the holding base, particularly by configuring the inner surface of the head adapter to face obliquely upward. It can be done very easily and the length of the holding base can be made close to the length of the cylindrical member, which saves material costs and allows the entire extrusion gun to be manufactured in a short length. In addition, the film pack can be prevented from biting in, and the film pack can be used efficiently, and the flow path of the through discharge passage is narrowed by the caulking portion of the film pack. Can prevent inconveniences such as the occurrence of liquid leakage of the contents by preventing or blocking and taking out and discarding the crushed used film pack Effect is achieved that work can be easily performed.

  An embodiment of the present invention will be described below with reference to FIGS. 1 to 30 in the accompanying drawings. 1 to 30, the same reference numerals may be used for the same or similar members as in FIGS. 53 to 54. In the description of FIG. 53 described above, there are portions that are not illustrated and description of the reference numerals of each member is omitted, but the reference numerals used and the action of the extrusion gun 10 are the same as those described below. The following description can also be referred to for the reference numerals of each member and the operation thereof.

  FIG. 1 is a cross-sectional view showing a state in which a cylindrical member 11 containing a film pack F is mounted on a known cartridge container extrusion gun 10 as described above. The extrusion gun 10 includes a main body 14 for extruding the contents C of the film pack F, for example, a sealing material, and the like, and is continuously connected to the main body 14 in a state of extending in front of the main body 14 and is cylindrical. It comprises a semi-cylindrical holding table 16 for holding the member 11. The film pack F is formed by filling the contents in a cylindrical film body and sealing the contents by caulking both ends with caulking members K.

  At the lower part of the main body 14, there are provided a grip 18 integrally connected downward from the main body 14, and a lever 22 pivotally attached to the grip 18 by a pin 20. . By pulling the lever 22, the push rod 28 spanned between the front plate 24 and the rear plate 26 is advanced from the upper rear of the main body 14 to the upper portion of the holding table 16.

  The push rod 28 passes through a push plate 32 that comes into contact with a pin 30 attached to the upper portion of the lever 22. The push plate 32 pulls the lever 22 so that the push rod 28 is inclined as shown by a chain line through the pin 30. The push rod 28 moves forward for each stroke of the lever 22 against the compression spring 36 fitted into the push rod 28 between the front plate 24 and the rear plate 26 due to friction between the through hole 34 and the push rod 28. It is supposed to be.

  Reference numeral 38 denotes a brake plate provided at the rear of the main body 14. The brake plate 38 brakes the pushed-out push rod 28 at the forward movement position and brakes the push rod 28 forward against the compression spring 40 when the push-out rod 28 is pulled backward. By pushing the plate 38, the brake of the push rod 28 is released.

  Reference numeral 42 denotes a piston pressing plate provided at the tip of the extrusion rod 28. The piston pressing plate 42 presses the piston body 84 of the cylindrical member 11, and seals or adhesive in the film pack F accommodated in the cylindrical member 11. The contents C are extruded.

  Reference numeral 46 denotes a fixed holding plate integrally formed at the front end of the holding table 16, and is formed with a U-shaped cutout portion 48 having an upper portion opened. The head adapter 50 is detachably attached to the fixed holding plate 46 through the notch 48. That is, the notch 48 functions as a mounting portion for the head adapter 50.

  The head adapter 50 has a substrate 52 that is in contact with the inner surface of the fixed holding plate 46 as well shown in FIG. Reference numeral 54 denotes an annular flange formed on the inner surface side of the substrate 52. The annular flange 54 is formed to have an outer diameter that is slightly smaller than the inner diameter of the tubular member 11 so that it can be inserted into and abutted with the open end of the tubular member 11.

  Reference numeral 58 denotes an opening formed in the center of the substrate 52. The outer diameter of the annular flange 54 may be slightly larger than the inner diameter of the cylindrical member 11 so that the cylindrical member 11 can be inserted into and abutted on the annular flange 54. Further, it is possible to omit the installation of the annular flange 54 as long as the contact state between the substrate 52 and the cylindrical member 11 is not hindered.

  A wall surface connecting the annular flange 54 and the step space 64 is formed in a slope shape, and a dome-like receiving slope 55 for facilitating reception of the circular portion at the tip of the film pack F is formed. Therefore, the front end portion of the film pack F is smoothly received by the receiving inclined surface 55, and the extrusion operation of the film pack F becomes smoother.

  The annular flange 54 and the substrate 52 may be connected to each other by a planar outer peripheral surface. However, in order to avoid the disadvantage that the receiving inclined surface 55 is thick and the material is excessive, it is shown in FIG. As described above, the annular cut portion 57 is formed on the outer peripheral surface side of the receiving inclined surface 55 so that the receiving inclined surface 55 can be thinned to save the material cost and reduce the weight. Reference numeral 59 denotes an annular step formed on the upper step of the receiving slope 55.

  Reference numeral 62 denotes a step portion formed on the outer surface side of the substrate 52, which has a shape that allows the cutout portion 48 of the fixed holding plate 46 to be inserted from the central portion of the substrate 52, and projects outward. Reference numeral 64 denotes a step space that can be opened on the inner surface side of the step 62 and open outward.

  Reference numeral 63 denotes a stopper portion that is suspended from the lower end of the outer side of the stepped portion 62. When the head adapter 50 is rotated, the stopper portion 63 is engaged with the corresponding portion of the fixed holding plate 46, thereby rotating the head adapter 50. It serves to control the excess.

  Reference numeral 65 denotes a pressing protrusion provided in an appropriate number (three in the illustrated example) on the inner surface of the tip of the step 62 (FIG. 8). As shown in FIG. 13, these protrusions 65 press and hold the outer surface of the tip of the nozzle step portion 77 of the nozzle body 74 when the nozzle body 74 is fitted inside the head adapter 50. It acts to hold firmly.

  Reference numeral 66 denotes spring means provided on the upper portion of the substrate 52. The spring means 66 has a bent spring piece 67 attached to the upper end of the substrate 52 and bent outward. An engagement member 69 is provided at the tip of the bent spring piece 67, and the engagement member 69 has a pair of inner engagement pieces 69 a and outer engagement pieces 69 b facing each other. An engagement gap 69d for sandwiching and engaging both edge portions is formed.

  The inner engagement piece 69a and the outer engagement piece 69b are not particularly limited as long as the engagement member 69 that sandwiches and engages both edge portions of the notch 48 is formed. In the illustrated example, as the inner engagement piece 69a, a flat plate body having an inverted U shape by extending the distal end portion of the bending spring piece 67 into a bifurcated shape is used.

  Further, if the distal end portion of the inner engagement piece 69a is bent inward so that the distal end is in contact with the substrate 52, there is an advantage that the work of inserting into the fixed holding plate 46 is performed smoothly. As the outer engagement piece 69b, an inverted U-shaped curved plate whose upper end is connected to the upper part of the inner engagement piece 69a so as to face the inner engagement piece 69a is used.

  Reference numerals 71 denote stoppers protruding on both sides of the upper end of the stepped portion 62. By locking the tip of the bent spring piece 67 to the stopper 71, the spring action of the bent spring piece 67 works in the direction of the substrate 52.

  Therefore, when the head adapter 50 is pivotably attached to the fixed holding plate 46 in a state where the engaging members 69 of the bending spring piece 67 are engaged with both end edges of the notch 48, the bending spring piece 67 is bent. The spring action of the spring piece 67 constantly biases the inner surface of the substrate 52 of the head adapter 50 so that it faces obliquely upward.

  Reference numeral 74 denotes a nozzle body having a nozzle portion 76 formed in a conical shape. The base outer surface portion of the nozzle body 74 has a shape corresponding to the inner surface shape of the head adapter 50. That is, a nozzle step 77 formed corresponding to the step space 64 of the head adapter 50 and a nozzle annular protrusion 78 formed corresponding to the opening 58 are formed at the base of the nozzle body 74. Has been. Reference numeral 79 denotes an annular edge formed corresponding to the annular step portion 59 of the head adapter 50, and maintains a good fitting state when the nozzle body 74 is inserted and fitted into the head adapter 50. Perform the action. Inside the nozzle step 77 and nozzle annular protrusion 78, a nozzle step space 77a and nozzle annular protrusion space 78a are provided in communication with each other. A through-discharge passage 80 communicating with the nozzle step space 77 a is formed in the nozzle portion 76.

  By inserting the nozzle body 74 having such a structure into the head adapter 50, both are detachably fitted (FIGS. 9, 12, and 13). In this case, when the film pack F is opened, the crimped portion K remaining at the leading end is stored in the stepped space 64, so that the crimped portion K blocks the through-hole 72 and the through-discharge passage 80. It is not at all.

  In use, as shown in FIGS. 12 and 13, the tip of the nozzle body 74 is cut to form a discharge port P and used at the tip of the through-discharge passage 80 of the nozzle body 74. In the illustrated example, the nozzle body 74 is detachably attached to the head adapter 50, but the nozzle body 74 and the head adapter 50 can of course be integrally formed.

  The cylindrical member 11 includes a cylindrical cylinder body 82 that is open at both ends, and a disk-shaped piston body 84 that is slidably inserted into the rear end opening of the cylinder body 82. . The piston body 84 includes a disc 88 having a hole 86 formed in the center thereof, and an annular rim 90 provided on the outer peripheral surface of the disc 88.

  The circular plate 88 may be a flat plate, but as shown in FIG. 16, an annular wall 87 projects from the peripheral edge of the hole 86, and the annular wall 87 and the annular rim 90 are connected to an appropriate number of reinforcing walls. It is preferable that the connection is made by 89 and the overall strength of the cylinder body 82 is improved. As shown in FIG. 17, when the outer surface of the annular wall 87 is configured to protrude outward from the outer surface of the annular rim 90, the pressing operation is performed when the film pack F is pressed by the piston body 84. There is an advantage of being carried out efficiently.

  The piston body 84 is slidable forward or backward, and both surfaces of the disc 88 are formed as a first pressing surface 88a and a second pressing surface 88b so that both surfaces can perform a pressing action. Yes.

  When the base end portion of the film pack F is pressed by the piston body 84, the crimped portion K of the base end portion of the film pack F is positioned in the hole 86 so as not to obstruct the pressing operation by the piston body 84. To do.

  The inner peripheral surface of the cylinder body 82 and the outer peripheral surface of the annular rim 90 of the piston body 84 may be smooth surfaces. However, as shown in the drawing, a large number of protrusions 92 are provided in the longitudinal direction of the inner peripheral surface of the cylinder body 82. It is preferable that a large number of concave grooves 94 are provided corresponding to the protrusions 92 in the sliding direction of the outer peripheral surface of the annular rim 90.

  With this configuration, when the contents C of the film pack F are discharged and the film pack F is folded, the film is smoothly folded and the inner peripheral surface of the cylinder body 82 and the outer peripheral surface of the annular rim 90 are Intrusion of the film pack in between is more effectively prevented.

  Further, the protrusion 92 and the concave groove 94 also serve as a guide when the annular rim 90 slides. Therefore, even if the width of the annular rim 90 is small, the piston body 84 can slide stably.

  If the flat portions 92a are formed without providing the protrusions 92 at both ends in the longitudinal direction of the inner peripheral surface of the cylinder body 82, the piston body 84 can be inserted into the inner peripheral surface of the cylinder body 82. There is an advantage that the insertion work becomes easy. Further, if a protruding stopper 92b is provided in the vicinity of both ends of the cylinder body 82, the piston body 84 can be slidably inserted into the inner peripheral surface of the cylinder body 82. Has an advantage that it does not easily fall off from the cylinder body 82 (FIG. 5).

  Since the piston body 84 is slidable forward or backward and both surfaces are pressing surfaces, the piston body 84 is first inserted into the rear end opening of the cylinder body 82 as shown in FIG. The film pack F is accommodated in front of the piston pack 84 and the piston body 84 is moved to the front end opening to discharge all the sealing material C from the film pack F (FIG. 2).

  Next, if the cylindrical member 11 is reversed while the piston body 84 is positioned at the front end opening (the state of FIG. 2), the piston body 84 is the rear end opening of the cylinder body 82 as in the first state. If the film pack is accommodated again in front of it, it can be reused in the same manner, and the cylindrical member 11 can be used semi-permanently by repeating it.

  Since the nozzle body 74 is used by being fitted to the inner surface side of the head adapter 50, the inner surface of the nozzle body 74 located on the inner surface side of the head adapter 50 is the contents even when the contents C are discharged. Although it is soiled by C, the inner surface side of the head adapter 50 is completely covered with the nozzle body 74, so that it is not soiled by the contents C at all.

  For this reason, the nozzle body 74 is discarded after an appropriate number of ejection operations. However, since the head adapter 50 is not soiled at all, it is only necessary to discard the nozzle body 74. Since it can be used repeatedly, the amount of waste can be reduced, and the amount of waste that becomes a source of toxic gas such as dioxin at the time of incineration of garbage can be reduced, thereby helping to solve environmental problems.

  The effect | action is demonstrated by said structure. First, as shown in FIGS. 9, 12, and 13, the nozzle body 74 is fitted into the head adapter 50 so that they are integrated [FIGS. 18, 30 (a) and (b)].

  Next, the integrated nozzle body 74 and the head adapter 50 are inserted and placed in the notch 48 of the fixed holding plate 46 and the stepped portion 62 of the head adapter 50 is inserted into the engaging gap 69 d of the engaging member 69. The both edges of the notch 48 are nipped and engaged, and the substrate 52 is inserted into the fixed holding plate 46 so as to be rotatable in the vertical direction with the substrate 52 positioned on the inner surface of the fixed holding plate 46 (FIGS. 19 and 30). (C)].

  At this time, the spring action of the spring means 66 works so as to extend in the direction of the substrate 52 of the head adapter 50, so that the inner surface of the substrate 52 is always biased so as to face obliquely upward.

  If the step adapter 62 is inserted into the notch 48 and the engaging member 69 provided on the bent spring piece 67 is pressed and inserted so that both end edges of the notch 48 are clamped and engaged, the spring is inserted. Due to the spring action of the means 66, the inner surface of the substrate 52 of the head adapter 50 is always urged so as to face obliquely upward.

  Then, the cylindrical member 11 having the piston body 84 slidably inserted in the rear end opening of the cylinder body 82 is prepared [FIGS. 20 and 30 (d)]. Next, the film pack F is accommodated in the cylinder body 82 from the opening at the front end of the cylinder body 82, and the leading end of the film pack F is cut with a nipper or the like H to open [FIG. 21 and FIG. ].

  It is a normal operation to keep the crimped portion K at the tip that is crimped with an aluminum wire or the like at the time of opening without being detached from the film pack F. This is because if it is cut off, the crimped portion K becomes garbage at the work site, and further, the film pack F is not fully opened. As described above, the caulking portion K adhering to the tip of the film pack F may cause a disadvantage that the flow path of the through hole 72 and the through discharge passage 80 is narrowed or clogged in the process of crushing the film pack. However, when the stepped space 64 is formed on the inner surface side of the head adapter 50 and the nozzle stepped space 77a is formed on the inner surface side of the nozzle body 74 as in the illustrated example, the stepped space 64 and the nozzle stepped space 77a are formed. Since the caulking portion K is accommodated therein (FIGS. 1 and 2), there is no accident in which each of the above-described channels is narrowed or clogged.

  As shown in FIGS. 19 and 21, the head adapter 50 has an inner surface of the substrate 52 facing diagonally upward, and the outer periphery of the annular flange 54 on the inner surface side of the head adapter 50 facing diagonally upward. The front end circumferential portion of the cylindrical member 11 containing the film pack F is inserted into the surface and closely joined to each other (FIGS. 22 and 30 (f)), and then the cylindrical member 11 is centered on the front end portion. As shown in FIG. 1, the cylindrical member 11 is placed on the holding table 16 of the push-out gun 10.

  Thereafter, by operating the lever 22, the push rod 28 and the pressing plate 42 are advanced to press the film pack F, and the film pack is folded and crushed while the sealing material in the film pack F is discharged. 23 and FIG. 30 (g)]. In a state where all of the sealing material and the like are discharged, the piston body 84 is positioned at the front end opening of the cylinder body 82 (state shown in FIG. 2).

  The crushed and folded film pack F is pressed against the substrate 52 and the annular flange 54 of the head adapter 50 in the state shown in FIG. 2 in a state where all the contents C in the film pack F are discharged. Yes. In order to take out the used crushed film pack F, the cylindrical member 11 is rotated upward about the tip end portion thereof, and the tip circumferential portion of the cylindrical member 11 is moved to the annular flange of the head adapter 50. The film pack F in a state of being removed from the outer peripheral surface of the portion 54 and pressed into the head adapter 50 may be taken out and discarded [FIGS. 24, 25 (a) (b) and 30 (h)].

  When the crushed film pack F adheres to the end side of the cylinder body 82 (FIG. 26 (a)), a new film pack F is inserted into the cylinder body 82. The crimped portion K of the new film pack F protrudes from the hole 86 of the piston body 84 and can be pressed to drop the film pack F, which can be discarded as it is [FIG. 26 (b)]. .

  In the case of a conventional cartridge container, the piston is slidable only in one direction (forward), and all the contents of the cartridge container are discharged, and when the piston comes to the foremost end, the cartridge container is sealed. Since the adhesive material such as the material is directly stored, the inside of the cartridge container is sticky and sticky even after discharge, and the cartridge container is discarded as it is not reusable. In the case of the present invention, the piston body 84 is slidable in two directions (front-rear direction) with the pressing surfaces 88a and 88b on both sides, and discharges all the contents of the film pack F. In the state where the film pack F comes, the film pack F is crushed, but the inner surface of the cylinder body 82 is not in direct contact with the contents C, so that the sealing material or the like C does not adhere to it, and the inner surface is at the start of use. No change.

  The change from the start of use is that the piston body 84 is located at the front end opening of the cylinder body 82, as shown in FIG. 24, but the cylinder body 82 is symmetrical, so it is reversed. As a result, the piston body 84 becomes exactly the same as the initial state located at the rear end opening of the cylinder body 82 [FIGS. 27 and 30 (i)].

  If another film pack F is accommodated from the opening of the cylindrical member 11 again in this state and operated in the same manner, the sealing material or the like C is again discharged from the other film pack F using the same cylindrical member 11. be able to. In this case, the pressing surface of the piston body 84 pressed by the pressing plate 42 is the second pressing surface 88b. If it does in this way, the same cylindrical member 11 can be used repeatedly.

  By such an operation, even after the contents C of the film pack F are pushed out, the inner surface of the nozzle body 74 is soiled, but the inner surface of the head adapter 50 is completely covered with the nozzle body 74 and therefore is not soiled. . Only the dirty nozzle body 74 is discarded after a predetermined number of extrusion operations (FIG. 30 (j)), and the new nozzle body 74 is newly inserted into the clean head adapter 50, thereby discarding the head adapter 50. It can be used over and over again semi-permanently. Therefore, it is possible to reduce the amount of waste that is a source of toxic gas such as dioxin during garbage incineration, and to help solve environmental problems.

  The operation of inserting the integrated nozzle body 74 and the head adapter 50 into the notch 48 of the fixed holding plate 46 may be performed according to the operator's request, and various procedures can be considered. This is illustrated in FIGS. 28 (a), (b) and (c).

  First, the head adapter 50 is placed on the upper surface of the holding base 16 of the push-out gun with the lower surface of the outer engagement piece 69b of the engagement member 69 locked to the upper edge of the notch 48 [FIG. 28 (a)]. .

  Next, the upper part of the rear end of the head adapter 50 is pressed forward with a finger, the lower surface portion of the head adapter 50 slides on the upper surface of the holding table 16, and at the same time, the lower surface of the outer engagement piece 69 b is the upper edge of the notch 48. The part is slid [FIG. 28 (b)].

  When the head adapter 50 is further pushed forward from the state of FIG. 28B, the outer engagement piece 69b gets over the upper edge of the notch 48, and the upper edge of the notch 48 enters the engagement gap 69d. Engage [FIG. 28 (c)].

  At this time, the head adapter 50 is attached to the fixed holding plate 46 with the outer surface side of the substrate 52 of the head adapter 50 positioned on the inner surface side of the fixed holding plate 46.

  The operation of removing the head adapter 50 inserted into the fixed holding plate 46 from the fixed holding plate 46 may be performed as desired by the operator. Illustrated in (c).

  First, in a state where the center portion of the outer engagement piece 69b of the head adapter 50 [FIG. 29 (a)] inserted into the fixed holding plate 46 is pushed downward with the thumb, it is attached to both end portions of the outer engagement piece 69b. On the other hand, an upward force is applied by two fingers to displace both ends of the outer engagement piece 69b to above the upper end edge of the notch 48 of the fixed holding plate 46 [FIG. 29 (b)].

  Next, the head adapter 50 and the nozzle body 74 are easily removed from the fixed holding plate 46 by moving the head adapter 50 upward and backward while the both end portions of the outer engagement piece 69b are displaced upward. [FIG. 29 (c)].

  In the above-described embodiment, the base end outer surface portion of the nozzle body 74 has a shape corresponding to the inner surface shape of the substrate 52, and the nozzle body 74 is inserted from the inside of the substrate 52 into the opening 58 of the substrate 52. Although the example in which the nozzle body 74 is attached to the head adapter 50 by matching the inner surface side of the substrate 52 and the base end outer surface portion of the nozzle body 74 has been shown, how the nozzle body 74 is attached to the head adapter 50 Is not limited to the above example, and other modes are also applicable. 31 to 41 show other embodiments of the present invention. 31 to 41, the same or similar members as those shown in FIGS. 1 to 30 are denoted by the same reference numerals. 31 to 41, the same or similar members as those shown in FIGS. 1 to 30 are denoted by the same reference numerals. The basic configuration of the embodiment of FIGS. 31 to 41 is the same as that of the embodiment of FIGS. 1 to 30. Therefore, the description thereof will be omitted and only the characteristic configuration will be described below.

  31 to 41, the head adapter 50 has a substrate 52 that is in contact with the inner surface of the fixed holding plate 46 (FIGS. 35 to 38). Reference numeral 54 denotes an annular flange formed on the inner surface side of the substrate 52. The annular flange 54 is formed to have an outer diameter that is slightly smaller than the inner diameter of the tubular member 11 so that it can be inserted into and abutted with the open end of the tubular member 11. Reference numeral 58 denotes an opening formed in the center of the substrate 52. The outer diameter of the annular flange 54 may be slightly larger than the inner diameter of the cylindrical member 11 so that the cylindrical member 11 can be inserted into and abutted on the annular flange 54. Further, it is possible to omit the installation of the annular flange 54 as long as the contact state between the substrate 52 and the cylindrical member 11 is not hindered.

  Reference numeral 62 denotes a step portion formed on the outer surface side of the substrate 52, which has a shape that allows the cutout portion 48 of the fixed holding plate 46 to be inserted from the central portion of the substrate 52, and projects outward. Reference numeral 64 denotes a step space formed on the inner surface side of the substrate 52 corresponding to the step 62.

  A wall surface connecting the annular flange 54 and the step space 64 is formed in a slope shape, and a dome-like receiving slope 55 for facilitating reception of the circular portion at the tip of the film pack F is formed. Therefore, the front end portion of the film pack F is smoothly received by the receiving inclined surface 55, and the extrusion operation of the film pack F becomes smoother.

  The annular flange 54 and the substrate 52 may be connected to each other by a planar outer peripheral surface. However, in order to avoid the disadvantage that the receiving inclined surface 55 is thick and the material is excessive, FIG. As shown in FIG. 36, an annular cut portion 57 is formed on the outer peripheral surface side of the receiving inclined surface 55 so that the receiving inclined surface 55 can be thinned to save the material cost and reduce the weight.

  Reference numeral 66 denotes spring means provided on the upper portion of the substrate 52. The spring means 66 has a bent spring piece 67 attached to the upper end of the substrate 52 and bent outward. An engagement member 69 is provided at the tip of the bent spring piece 67, and the engagement member 69 has a pair of inner engagement pieces 69 a and outer engagement pieces 69 b facing each other. An engagement gap 69d for sandwiching and engaging both edge portions is formed.

  The inner engagement piece 69a and the outer engagement piece 69b are not particularly limited as long as the engagement member 69 that sandwiches and engages both edge portions of the notch 48 is formed. In the illustrated example, as the inner engagement piece 69a, a flat plate body having an inverted U shape by extending the distal end portion of the bending spring piece 67 into a bifurcated shape is used. As the outer engagement piece 69b, an inverted U-shaped curved plate having an upper end connected to the upper portion of the inner engagement piece 69a via a connection piece 67a so as to face the inner engagement piece 69a is used. It has been. Note that 69c is a knob provided on the front side of both lower ends of the outer engagement piece 69b, and is provided to facilitate the operation when the outer engagement piece 69b is operated. .

  Reference numerals 71 denote stoppers protruding on both sides of the upper end of the stepped portion 62. By locking the tip of the bent spring piece 67 to the stopper 71, the spring action of the bent spring piece 67 works in the direction of the substrate 52.

  Therefore, when the head adapter 50 is pivotably attached to the fixed holding plate 46 in a state where the engaging members 69 of the bending spring piece 67 are engaged with both end edges of the notch 48, the bending spring piece 67 is bent. The spring action of the spring piece 67 constantly biases the inner surface of the substrate 50 of the head adapter 50 so as to face obliquely upward.

  Reference numeral 68 denotes a nozzle body mounting portion protruding from the tip of the stepped portion 62. A male screw portion 70 is formed on the outer peripheral surface of the nozzle body mounting portion 68, and a through-hole 72 communicating with the step space 64 is opened inside. The step space 64 is formed larger than the through hole 72.

  Therefore, since the crimped portion K remaining at the leading end when the film pack F is opened is stored in the stepped space 64, there is a possibility that the crimped portion K may block the through hole 72 and the through discharge passage 80. Not at all.

  Reference numeral 74 denotes a nozzle body formed in a conical shape. An annular flange 176 is provided on the entire base of the nozzle body 74 (FIG. 39). On the inner peripheral surface of the flange 176, a female screw portion 178 that is screwed with the male screw portion 70 on the outer peripheral surface of the nozzle body mounting portion 68 is formed (FIGS. 31 and 32).

  The nozzle body 74 can be attached to the head adapter 50 by screwing the nozzle body 74 to the nozzle body mounting portion 68. A through discharge passage 80 communicating with the through hole 72 is formed in the nozzle body 74.

  In use, the tip of the nozzle body 74 is cut at the tip of the penetrating discharge passage 80 of the nozzle body 74 and used as shown in FIG. In the illustrated example, the nozzle body 74 is detachably attached to the head adapter 50, but the nozzle body 74 and the head adapter 50 can of course be integrally formed.

  In the above-described embodiment, the case where the engaging member 69 is attached to the substrate 52 via the bending spring piece 67 has been described as a preferred example. However, the engaging member 69 is not necessarily connected to the substrate 52 by the bending spring piece 67. It is not always necessary to urge the inner surface of the substrate to be obliquely upward, and a structure in which the engaging member 69 is simply pivotably attached to the substrate 52 by, for example, a hinge means or the like can be adopted. If necessary, the cylinder body 82 can be attached and detached manually so that the inner surface of the substrate 52 faces obliquely upward.

  In the above-described embodiment, the head adapter 50 is attached to both edge portions of the notch portion 48 of the fixed holding plate 46 so as to be rotatable in the vertical direction, and the inner surface of the substrate 52 can be directed obliquely upward. However, in the present invention, it is not always necessary for the head adapter 50 to rotate in the vertical direction. For example, as shown in FIGS. 42 to 46, a configuration in which the head adapter 50 does not rotate is adopted. You can also.

  42 to 46, a pair of spring members 62a and 62a are provided at the tip of the stepped portion 62. The spring members 62a and 62a always have a function of biasing in the proximal direction. The spring members 62a and 62a always press the outer surface of the fixed holding plate 46 in a state where the head adapter 50 is attached to the fixed holding plate 46, and securely fix the head adapter 50 to the fixed holding plate 46. Acts to prevent falling off.

  As shown in FIGS. 42 and 43, first, the nozzle body 74 is inserted into the head adapter 50 to integrate them. The fixed holding plate with the integrated nozzle body 74 and the head adapter 50 inserted and placed in the notch 48 of the fixed holding plate 46 and the substrate 52 in close contact with the inner surface of the fixed holding plate 46. 46 is inserted.

  The procedure for inserting the head adapter 50 into the notch 48 of the fixed holding plate 46 is shown in FIGS. If the head adapter 50 is pressed and inserted from above into the cutout portion 48 so that the stepped portion 62 is inserted, the head adapter 50 is in a state where the spring members 62a and 62a press and urge the outer surface of the fixed holding plate 46. The fixed holding plate 46 is inserted. At this time, since the spring members 62a and 62a always press the outer surface of the fixed holding plate 46, the head adapter 50 does not move or fall off.

  Even if the spring members 62a and 62a are not used, the head adapter 50 can be positioned on the inner surface side of the fixed holding plate 46, and the installation of the spring members 62a and 62a can be omitted.

  For example, a head adapter 50 as shown in FIGS. 47 to 49 can be employed. 47-49 are the same as those in FIGS. 31-41. Further, it is possible to omit the installation of the annular flange 54 as long as there is no problem in the contact state between the substrate 52 and the cylindrical member 11.

  Further, as shown in FIGS. 50 to 51, a wall surface connecting the annular flange 54 and the step space 64 is formed in a slope shape, and a dome-like shape is formed to make it easy to receive the circular portion at the tip of the film pack F. If the receiving inclined surface 55 is formed, the front end portion of the film pack F is smoothly received by the receiving inclined surface 55, and the pushing operation of the film pack F becomes smoother. As shown in FIG. 47, the annular flange 54 and the substrate 52 may be connected to each other by a planar outer peripheral surface. However, there is a disadvantage that the receiving inclined surface 55 is thick and the material is excessive. In order to avoid this, as shown in FIGS. 50 and 51, an annular cut portion 57 can be formed on the outer peripheral surface side of the receiving inclined surface 55 to make the receiving inclined surface 55 thinner, thereby saving material costs. .
