Description

  The present invention extrudes a material composed of two components, such as a main agent and a curing agent, contained in a film pack, such as an anchor bolt fixing material, an adhesive, and a sealing material in the field of construction and civil engineering (hereinafter also referred to as a caulking gun). The present invention relates to a cartridge system for an injection material for use in a set.

  An injection material cartridge system for discharging and injecting a fluid substance such as an adhesive or a sealing agent to a target injection position is widely used. As a fluid substance used here, there is a sealing material or a caulking material in a building or civil engineering as a form (hereinafter also referred to as a one-pack type injectant) used by injecting a single component fluid substance alone. . On the other hand, as a form used by mixing and injecting a two-component flowable substance at a prescribed mixing ratio (hereinafter also referred to as a two-pack type injection), there are an adhesive, a filler, an anchor bolt fixing material, and the like. .

  In the case of a conventional one-pack type injection, a cartridge for injection material is provided in which a fluid substance is accommodated in a container molded in a cylindrical shape with polyethylene or polypropylene. In addition, the two-pack type injectant includes two storage cylinders that individually store two-component flowable substances (for example, one is the main agent and the other is the curing agent) in a cylindrical container made of polyethylene or polypropylene. An injection material cartridge is provided which is connected side by side and has an integrated structure.

  Furthermore, in recent years, from the viewpoint of reducing the amount of waste after use, considering the environment, and reducing the amount of waste in packaging materials, a flexible material such as a laminate film can be used to reduce the amount of packaging material waste. There is provided a cartridge for an injection material that is used by inserting a film pack accommodated in a cylindrical holder into a cylindrical holder and setting it in an extrusion gun such as a caulking gun.

For example, in Patent Document 1 below, a flexible and cylindrical film container is preliminarily filled with a high-viscosity fluid, and both ends of the film container are bound and loaded into a cylindrical container of a caulking gun. A method for applying a high-viscosity fluid such as a sealing material that cuts off the caulking discharge side end of the film container and extrudes a high-viscosity fluid from the other end side is disclosed.
In this case, cutting tools such as scissors and knives are required to cut off the end of the film container on the caulking discharge side, which not only increases the number of work steps, but also may cause dirty hands or injury when cutting. There are some problems. In addition, since one end of the film pack is cut before the nozzle cap (discharge head) is attached, there is a problem that the fluid substance overflows from the main body to the outside due to the internal pressure of the film pack and adheres to the hand or the extrusion gun. is there.

As a cartridge system for an injection material that does not require a tool, for example, in Patent Document 2 below, a cartridge main body provided with a discharge port portion having a cylindrical shape at a distal end portion, and a base end of the discharge port portion of the cartridge main body are provided. In a discharge gun cartridge comprising a nozzle to which the nozzle is mounted and the opening inside the discharge port being shielded by a sealing sheet, the nozzle is detachably inserted into the discharge port at the base end of the nozzle An insertion tube portion to be formed, and at the distal end portion of the insertion tube portion, when the insertion tube portion is inserted into the discharge port portion, a rupture portion that presses against the sealing sheet and breaks it is formed. The tip of one side part of the insertion part is located outside the opening end inside the discharge port part, and the tip of the other side part of the insertion tube part is located inside the opening end inside the discharge port part. , One side portion of the insertion tube portion and Cartridge dispensing gun is disclosed which is characterized in that the length of the side has been set, respectively.
In this case, since there is a lid and a reinforcing ring with the discharge port portion shielded by a sealing sheet at the front end and a bottom portion at the rear end, the shape of the film pack becomes complicated and only the manufacturing cost of the film pack itself increases. In addition, continuous production is difficult even when filling the contents. Furthermore, since the lid, the reinforcing ring, and the bottom also become waste, there is a problem that the amount of waste increases.

  As a two-part injection, for example, as described in Patent Document 3 below, each has a closed end and an open end, and each closed end has two parallel cylinders having passages therethrough. Consisting of a housing and a fixing means (mixing nozzle mounting) on the outside of the closed end for mounting a mixing nozzle for mixing the two-component mixture with respective passages, each said cylinder being pushed out of the compounding gun Disclosed is a disposable manifold unit (discharge head) for a compounding gun for a two-component sausage pack having a length and diameter sufficient to receive and hold the sausage pack. The unit includes a perforating nozzle for perforating a sausage pack (film pack).

  In this case, the cartridge system for the injection material has a structure (two) in which the main agent and the curing agent are stored in separate film packs, and two film packs are connected side by side to the discharge head and integrated. Since the curing agent is stored in individual foil packs, the number of work steps is increased when they are bonded to each other, and the two-component injection agent has a different mixing ratio of the main agent and the curing agent depending on the type of adhesive. For each type of adhesive, film packs with different sizes (thicknesses) corresponding to the respective mixing ratios, storage cylinders, and dedicated expensive extrusion guns must be prepared, resulting in a lack of versatility. . Furthermore, the perforating nozzle is fixed, and the film pack may be accidentally opened during storage before use or during transportation.

Further, for example, in Patent Document 4, a plurality of types of stock solutions constituting an injection material such as an adhesive and a sealing material are divided and accommodated inside, and set in an extrusion gun to be used for injection of the injection material. A cartridge for a material, which has a cylindrical main body, a discharge port provided at a front end portion of the cylindrical main body, and a cylindrical shape provided by pressing from a push-out piston of the push-out gun provided at a rear end portion of the cylindrical main body. Each stock solution constituting the injection material is divided into a stock solution container that encloses and stores the stock solution with a film inside a casing formed of a piston member that is pushed into the cylindrical body toward the tip of the body. An injectable material cartridge is also disclosed which is characterized in that it is contained.
As shown in FIG. 11, in the cartridge for injection material described in Patent Document 4, a drawing member for drawing out from the discharge opening is connected to the film pack, and one end of the film pack is drawn and cut by the drawing member. By doing so, the film pack is opened. In this case, there is a problem that a cutting tool is required, and not only the work process is increased, but also the hand may be soiled or injured when cutting. Furthermore, since the film pack has a structure that passes through the discharge opening, there is a problem that the discharge opening becomes narrow, the discharge resistance becomes high, and the discharge mixing ratio becomes unstable.

Further, for example, Patent Document 5 discloses an adapter (discharge head) for collecting a substance from a multi-chamber tubular bag, particularly for collecting a substance from a two-chamber tubular bag, which is collected from the bag chamber. In which the substance is guided almost separately in the adapter (discharge head), the adapter has at least two through passages for conveying the substance contained in the bag chamber through the adapter, An adapter for collecting a substance from a multi-chamber tubular bag, wherein the inner wall of the through-passage is in direct contact with the substance when discharging the substance contained in the bag chamber (Discharge head) is disclosed.
As shown in FIG. 12, a needle-like or spike-like projecting tool or cutting tool is described as a shape of the piercing member. Since it is not ensured, there is a problem that the discharge resistance increases or the discharge mixing ratio of the contents becomes unstable. There is no specific description of the cutting tool. In Patent Document 5, the shape of the inner surface of the receiving portion of the ejection head is not particularly limited. Further, from the disclosed figures, since the contents stay in the discharge head, the discharge mixing ratio is not constant, and particularly when the discharge starts, the content is not discharged at a predetermined mixing ratio, There seems to be a possibility of leaking to the outside through the gap of the film pack. Furthermore, it is disclosed that the film is opened simultaneously. However, when the difference in the mixing ratio of the two component flowable substances is large, when the extrusion from the film pack is started for the first time (also referred to as the beginning of discharge). Since it becomes difficult to discharge the flowable substance on the small cross-sectional area side part (hereinafter also referred to as the small cross-sectional area side part) of the two-chamber film pack, the predetermined discharge mixing ratio is not achieved and the number of discarded shots increases. There is a problem that the contents are wasted, resulting in a large amount of waste.

  Patent Document 5 discloses a case in which the opening means is fixed. However, if the opening means is fixed, the film pack may be accidentally opened during storage before use or during transportation. Although the case where it can be attached to the adapter (discharge head) from the outside is also disclosed, the attachment position is not particularly specified, and in the case of the position shown in the figure, the part with the opening means is outside the discharge head. Since it has a penetrating shape, the contents may leak out from the portion.

Hereinafter, the present invention will be described in detail.
As shown in FIG. 1, the cartridge of the following embodiment includes a two-chamber film pack 1, a cylindrical holder 2, a discharge head 3, a cylindrical cutting blade 4, and a mixing nozzle that separately contain and contain two components of a fluid substance. 7 is the main component.
The two-component flowable substance in the present invention is used as an injection material by mixing two components of a main agent and a curing agent at a specified mixing ratio, and is an epoxy resin, vinyl ester resin, urethane resin, urethane acrylate. Resins, phenol resins, melamine resins, urea resins, unsaturated polyester resins, acrylic resins and the like can be mentioned.

  Generally, the anchor bolt fixing material is an epoxy resin, vinyl ester resin, unsaturated polyester resin, urethane acrylate resin, or the like filled with fillers such as calcium carbonate and cinnabar sand. Moreover, the viscosity of the main component of the anchor bolt fixing material and the curing agent is 5 to 30 Pa · s (spiral viscometer PCU-205 (manufactured by Malcolm Corporation) 50 rpm 25 ° C.), preferably 8 to 15 Pa · s. .

  As shown in FIG. 2, the film pack 1 according to the present invention has a flexible film (film body) in accordance with a mixing ratio of two component fluid substances (hereinafter also referred to as contents, main agent, or curing agent). It is formed into a cylindrical shape separated into two chambers with a cross-sectional area. In particular, when the mixing ratio of the two components is large, the film pack inevitably becomes a two-chamber film pack having a small cross-sectional area side portion 1a and a large cross-sectional area side portion 1b. The filling of the contents is performed, for example, by sealing one end of the two-chamber film pack, filling the fluid substance, and sealing the other end. Sealing at both ends can be bound by a clasp 12 such as a clip or the like. However, since the contents ooze out, heat sealing 11 is preferable. More preferably, at least the discharge side is heat-sealed 11 by gusset folding, so that the abutting portion of the cylindrical cutting blade 4 can be easily discriminated, and the large cross-sectional area side portion 1b (main agent) and the small cross-sectional area side during discharge The unsealed area of the part 1a (curing agent) is easily secured, and the mixed discharge ratio is constant. In addition, the method (direction) of folding the caseette is preferably to process (fold) the large cross-sectional area side portion 1b in order to secure the area of the small cross-sectional area side portion 1a.

  The material of the film body used for the film pack 1 is required to have chemical resistance and barrier resistance. Depending on the type of contents, for example, a laminate of an aluminum thin film and a resin sheet can be used. The thickness of the film is not particularly limited, but if it is too thick, it will be difficult to break through the film pack 1 with the cylindrical cutting blade 4, and the film will not be properly folded during ejection. Moreover, when too thin, there exists a possibility that the film pack 1 may burst at the time of storage and transportation. The substantial thickness is preferably in the range of 10 to 300 μm, preferably 50 to 200 μm, and more preferably 80 to 120 μm.

As shown in FIG. 3, the cylindrical holder 2 in the present invention includes a cylinder 21 and a piston 22. The cylindrical holder 2 only needs to be substantially hollow, and the shape can be designed freely. However, in view of the structure of a generally used extrusion gun, a cylindrical holder is preferable.
The cylindrical holder is required to reduce the frictional resistance when discharging the contents and to prevent the film of the film pack 1 from being bitten. Although there is no particular limitation, a cylinder comprising a plurality of linear grooves in the longitudinal direction on the inner wall and a piston having wings for sliding along the linear grooves, or a flange on the outer periphery of the cylindrical cylinder. The thing which consists of the provided piston can be used. Moreover, it is preferable that the front-end | tip (film pack side) of piston 22 becomes the convex type 23 in order to keep the content in the film pack 1 as much as possible. Particularly preferably, the shape is approximately the same as the shape of the inner surface of the ejection head and is smaller by 1 mm to 2 mm.
Various types of materials can be used as the material of the cylindrical holder 2, and examples thereof include paper, metal, plastic, fiber reinforced plastic, ceramic, and the like. From the viewpoint of manufacturability and cost, injection molded plastic is preferable.

  In some cases, as shown by 5b in FIG. 4, the holder is integrated with the extrusion gun.

As shown in FIG. 5, the ejection head 3 according to the present invention includes a pressing portion 35 and a holding portion 34. The holding portion 35 has a discharge opening 32, and a mixing nozzle connecting portion 31 that communicates with the discharge opening 32 is provided on the outer tip side portion. The shape of the discharge receiving portion 33 that forms the inner surface of the holding portion is not particularly limited, but it is necessary to prevent the contents from staying at the start of discharge. Preferably, the shape of the end of the film pack 1 that is in contact is approximately the same.
Various types of materials can be used for the discharge head 3, and examples thereof include paper, metal, plastic ticks, fiber reinforced plastics, ceramics, and the like, but injection molded plastics are preferable from the viewpoint of manufacturability and cost.

  As will be described in detail below, as shown in FIG. 9, the discharge head 3 is provided with a cylindrical cutting blade 4 in a state in which it can slide back and forth in parallel with the discharge direction.

As shown in FIG. 6, the cylindrical cutting blade 4 includes V-shaped cut portions 41 and 42 having a cylindrical shape and a sharp tip.
In particular, when the mixing ratio of the main agent and the curing agent is large, when the main agent having a large ratio (large cross-sectional area side portion 1b) is opened and discharged, the hardener having a small ratio (small cross-sectional area side portion 1a) becomes difficult to open. As a result, only the main agent is discharged at the beginning of discharge. Therefore, in order to discharge at an appropriate discharge mixing ratio from the beginning of discharge, it is desirable that the cut portion is shaped so that the small cross-sectional area side portion 1a is opened.
Although the cut part 41 of one place may be sufficient, Preferably, it is preferable to provide the cut part 41 and the cut part 42 in two places up and down in the shape of a bowl. Furthermore, since the body part of the cylindrical cutting blade 4 has the opening part 43 through which a fluid substance passes, the flow path for the content to be extruded can be ensured.

  As shown in FIG. 7, in the case of one cut portion 41, the film pack 1 is reliably cut by breaking through the film from the small cross-sectional area side portion 1 a of the film pack 1 and then penetrating to the large cross-sectional area side portion 1 b. The small cross-sectional area side portion 1a is opened, and the effect of stabilizing the discharge mixing ratio from the beginning of discharge is obtained.

  On the other hand, as shown in FIG. 8, in the case of the two cut portions 41 and 42, the film is pierced from the small cross-sectional area side portion 1a and then pierced and penetrated through the large cross-sectional area side portion 1b. It is opened from the small cross-sectional area side portion 1a, and the effect of stabilizing the discharge mixing ratio from the beginning of discharge is obtained. In order to obtain such an effect reliably, as shown in FIGS. 8 and 9, on the side where the small cross-sectional area side portion 1 a of the film pack 1 abuts out of the two cut portions at the top and bottom of the cutting blade 4. A certain upper side (C-D) needs to be made 1 mm to 8 mm longer than the lower side (E-F). Furthermore, since the body part of the cutting blade 4 has the opening 43 through which the fluid substance passes, a flow path for pushing out the contents is also secured.

Moreover, as shown in FIG. 6, it is preferable that the angle 45 of the V-shaped cut end is processed at 100 degrees or less, and more preferably, it is 30 degrees to 80 degrees in consideration of the ease of breaking through the film. preferable.
On the other hand, it is preferable to process the angle 44 of the cylindrical cutting blade 4 at 70 degrees or less, More preferably, it is 20 degrees-50 degrees in consideration of the ease of breaking through a film.

  As shown in FIG. 9, the length of the cylindrical cutting blade 4 is set such that when used, that is, when the mixing nozzle is mounted on the mixing nozzle mounting portion provided outside the front end of the discharge head pressing portion, By designing the tips 41 and 42 of the cut portion of the cylindrical cutting blade 4 to protrude about 10 mm to 20 mm from the receiving portion 33 of the discharge head 3 that forms the inner surface of the holding portion, the film pack 1 can be reliably broken through. And ensuring the passage of the flowable substance.

As shown in FIGS. 7 and 8, the opening 43 provided in the body of the cylindrical cutting blade 4 stops in each chamber of the film pack 1 when the cylindrical cutting blade 4 breaks through the film pack 1. It is provided as follows. The shape of the opening 43 is not particularly limited, and examples thereof include a pentagon, a circle, and an ellipse.
The cylindrical cutting blade 4 may be mounted at the time of use, but may be mounted before use. When it is mounted before use, it is necessary not to project on the inner surface of the discharge head, or to prevent it from breaking through the film pack 1 during storage and transportation. In any case, when the mixing nozzle 7 is mounted on the mixing nozzle mounting portion 31 of the discharge head 3, the cylindrical cut blade 4 is automatically pressed to break through the film pack 1 or discharge with the extrusion gun 5a. The length of the cylindrical cut blade 4 is required to be long enough to push the film pack 1 with the discharge pressure at that time and pierce the film pack 1 with the cylindrical cut blade 4.

Various types of materials can be used for the cylindrical cutting blade 4, and examples thereof include paper, metal, plastic tick, fiber reinforced plastic, and ceramic. Metal and plastic are preferable, and injection molding is performed from the viewpoint of manufacturability and cost. Plastic is the best.
The film pack 1 and the discharge head 3 may or may not be bonded, but for the purpose of preventing the backflow of the flowable substance to the cylindrical holder portion 2, the film pack 1 and the discharge head 3 may be bonded with an appropriate sealant (adhesive). Preferably it is.

  The mixing nozzle 7 attached to the ejection head 3 in the present invention is not restricted at all, and a commercially available one can be used. For example, there is a static mixer in which a mixing element is accommodated in a cylindrical housing.

  As shown in FIG. 4, the extrusion gun according to the present invention may be any as long as the cartridge system for an injection material according to the present invention can be set, and examples thereof include a manual type, an air type, and an electric type.

  As shown in FIG. 10, when using the cartridge for injection material according to the present invention having the above-described configuration, for example, a film pack 1 containing a fluid substance such as an adhesive or a sealing material is attached to a cylindrical holder. 2 is inserted, the discharge head 3 is mounted at the tip, and set on the extrusion gun 5a. In the case of the cylindrical cutting blade 4a having one cut portion, the orientation is adjusted so that the tip of the cutting blade hits the small cross-sectional area side portion 1a of the film pack 1, and the cylindrical cutting blade 4b having two cut portions is provided. In this case, the orientation is adjusted so that the longer cut portion hits the small cross-sectional area side portion 1 a of the film pack 1, and the cut portion is inserted into the discharge opening 32 of the discharge head 3. When the mixing nozzle 7 is mounted on the mixing nozzle mounting portion 31, the cylindrical cut blade 4 on the inner surface of the discharge head protrudes. A desired part of the film pack 1 is automatically pierced by the cylindrical cutting blade 4 or the film pack 1 is pushed forward by a pressing force from the pushing piston of the pushing gun, and the desired part of the film pack 1 is pushed. Will be broken through. At this time, it is surely broken in order from the small cross-sectional area side portion 1a.

Further, when extruded with an extrusion gun, the content of the film pack 1 passes through the inside of the cylindrical cutting blade 4 from the opening 43 provided at the tip of the cylindrical cutting blade 4 and / or the cutting blade body. The mixture is extruded to the mixing nozzle 7 and stirred and mixed in the mixing nozzle 7. As a result, a fluid substance (two components) having a desired blending ratio is supplied from the tip of the mixing nozzle.
As described above, the injection material cartridge system of the present invention is provided with a mechanism for breaking through the film pack 1 by inserting the cylindrical cut blade 4 into the discharge opening 32 of the discharge head 3 and mounting the mixing nozzle 7. In addition, since the small cross-sectional area side portion 1a is designed to be opened first, the contents are discharged and mixed at a desired mixing ratio from the beginning of discharge. Further, when the mixing nozzle 7 is mounted on the discharge head 3, the cylindrical cutting blade 4 protrudes from the inner surface of the discharge head 3 toward the inner surface toward the film pack 1, so that, for example, the mixing nozzle 7 is attached to the discharge head 3. Even if the film pack 1 and the discharge head 3 are joined and stored and transported without being mounted, the film pack 1 will not be opened by mistake. Furthermore, since a cutting tool for cutting one end of the film pack 1 is not required at the time of opening, there is no risk of contact with the human body or injury. Moreover, since the film pack 1 storing each fluid substance is extended along the central axis of the cylindrical holder 2, the mixing ratio (mixing ratio) of the plurality of fluid substances in the mixing nozzle 7 is as follows. It is always kept constant, and the properties and characteristics of the adhesive extruded from the tip of the mixing nozzle 7 are also stable.
Further, since the film pack 1 is formed of a thin film body, the film pack 1 is crushed as it is used, and after use, the film pack 1 is folded into the receiving portion 33 of the discharge head 3, and the amount as waste. And can be easily transported and processed.

  The cartridge system for injecting material according to the present invention includes various adhesives in various fields such as architecture, civil engineering, medicine, electronics, machine industry, powder industry, metal processing, etc. Can be used for discharging and mixing, and is particularly suitable for anchor bolt fixing materials.
