The present invention relates to a film insertion device that can securely insert a cylindrical film into a coming insertion body.
[0002]
[Prior art]
For example, as a cylindrical film insertion device for inserting a cylindrical film such as a cap seal into a mouth portion of a bottle container or the like, for example, there is one disclosed in Japanese Utility Model Laid-Open No. 60-177001. As shown in FIG. 4, the tubular film insertion device 50 is accommodated in a long belt-like tubular film f to be supplied, and an opening means 51 that opens the tip of the tubular film f, The tubular film f fed out while being opened by the opening means 51 is cut to a predetermined length below the opening means 51, and is appropriately opened by the opening means 51. The cap seal cs made of the tubular film f cut into the shape is shaped into a substantially cylindrical shape so as to be fitted into the mouth portion of the bottle container b, and shaped into a substantially cylindrical shape by the shaping means 53. It is comprised from the insertion means 54 which inserts the cap seal cs in the opening | mouth part of the bottle container b.
[0003]
The shaping means 53 is attached so as to project radially from the rotary shaft 53b, and can be opened and closed in a circulating manner while stopping at the delivery position α ₅₀ and the insertion position β ₅₀ as the rotary shaft 53b rotates. It comprises a mandrel 53a, cap seal cs which is suitably opened by the opening means 51, in the delivery position alpha _50, is passed to the shaping means 53 by being inserted into the mandrel 53a which is stopped in the closed state , cap seal cs is fitted interpolated mandrel 53a is by opening during movement in the fitting position beta _50, the cap seal cs is shaped in a substantially cylindrical shape.
[0004]
Wherein the inserting means 54 in the inserting position beta _50, has an extrusion rod 54a of lifting in that state while being inserted between the mandrel 53a which is stopped in the open state, by the extrusion rod 54a, By pushing the cap seal cs downward from the mandrel 53a, the cap seal cs is fitted into the mouth portion of the bottle container b located directly below the mandrel 53a.
[0005]
[Problems to be solved by the invention]
By the way, the inner diameter of a tubular film such as a cap seal formed by a shrink film is generally set larger than the diameter (outer diameter) of the mouth portion of a container or the like to which the tubular film is to be attached. Therefore, for example, as shown in FIGS. 5A and 5B, when the conveyance interval of the container B conveyed to the film insertion position α is narrow, it is intended to be inserted into the mouth portion of the container B. The lower end portion of the tubular film F to be abutted against the upper end portion of the adjacent tubular film F already fitted in the mouth portion of the container B, and the tubular film F is smoothly and reliably attached to the mouth portion of the container B. There is a problem that it can not be inserted into.
[0006]
In particular, when the tubular film F to be inserted into the mouth portion of the container B is supplied in a state of being folded into a sheet shape, the tubular film F has a crease or the like. As shown in (a) and (b), the tubular film F folded in a sheet shape cannot be opened in a complete cylindrical shape, and the fold portion is in a projecting state. There is also a possibility that the fold portion may easily come into contact with the upper end portion of the adjacent cylindrical film F that is already inserted into the mouth portion of the container B.
[0007]
For this reason, in the conventional film insertion device, when containers are conveyed at a narrow interval, in the vicinity of the film insertion position, the container conveyance interval is temporarily widened by a screw conveyor, a star wheel, or the like. A cylindrical film such as a cap seal is inserted into the mouth portion of the container.
[0008]
However, for the purpose of improving the self-supporting stability of the container during transportation, when a plurality of containers are housed in the case, there is almost no gap between adjacent containers housed in the case. Therefore, in the state accommodated in such a case, the interval between the containers cannot be increased, and it is difficult to fit a cylindrical film such as a cap seal into the mouth portion of the container.
[0009]
Accordingly, an object of the present invention is to provide a film insertion device capable of smoothly and surely inserting a tubular film into a fitting insertion body even when the fitting insertion body such as a container is conveyed at a narrow interval. Is to provide.
[0010]
[Means for solving the problems and effects thereof]
In order to solve the above-mentioned problem, the invention according to claim 1 is a film insertion device for inserting a cylindrical film into an inserted body that is sequentially conveyed to a film insertion position, and at a predetermined position. After the film is inserted, a plurality of mandrels are sequentially conveyed to the film insertion position so as to follow the conveyance path of the inserted object, and the film is pushed out from the mandrel at the film insertion position. Film extruding means that is inserted into the inserted insert that has been conveyed to a position facing the mandrel, and each film extruding means of a plurality of adjacent mandrels is fitted into the film along the conveying path of the inserted insert. In the insertion position, before the film is completely inserted into the mouth portion of the inserted body from the previous mandrel, the film is operated one after another so that the film is pushed out from the next mandrel. And, by film extrusion means, the film extruded from the mandrel, while maintaining the state in which the leading end portion of the extruding direction is in contact with the outer peripheral surface of the adjacent film extruded previously is fitted onto the fitting interposer The film insertion apparatus characterized by this is provided.
[0011]
In the film insertion device configured as described above, each film extruding means of a plurality of adjacent mandrels is inserted into the film from the previous mandrel at the film insertion position along the transport path of the object to be inserted. Since the film is operated one after another so that the film is pushed out from the next mandrel before being completely inserted into the mouth portion of the film, the film pushed out from the mandrel by the film pushing means is the tip in the pushing direction. Is inserted into the insertion insert while maintaining the state of contacting the outer peripheral surface of the adjacent film that has been extruded first, so the conveyance interval of the insertion insert being conveyed to the film insertion position is narrow In addition, even if the mandrel installation interval is narrowed accordingly, the end of the film extruded from the end is adjacent to the end of the adjacent film extruded first. Without contact, extruded from the mandrel film is inserted securely fitted to the fitting interposer purposes.
[0012]
Also, as in the film fitted apparatus according to claim 2, a plurality of the mandrel, over a pulley arranged to open the endless chain or a predetermined interval passed over a sprocket disposed at predetermined intervals The endless chain or the timing belt is attached to the passed timing belt so as to project outward in the same plane on which the timing belt moves , and a film is inserted into the mandrel at the arc portion of the sprocket or pulley. In such a case, even when the installation interval of the mandrel is narrowed in accordance with the insertion object to be transported at a narrow interval, the arc of the sprocket or the pulley has the tip of the adjacent mandrel. Since the gap increases, the cylindrical film can be securely placed on the mandrel without being caught by adjacent mandrels. It can be fitted into.
[0013]

Two sets are provided so as to correspond to the confectionery containers P conveyed in parallel.
[0016]
As shown in FIGS. 3 (a) and 3 (b), the seal insertion device 4 includes sprockets 11a and 11b arranged at predetermined intervals, and an annular endless member spanned over the sprockets 11a and 11b. The chain 12 is provided with a plurality of mandrels 13 attached to the continuous chain elements 12a constituting the endless chain 12 so as to project outward, and a seal supply is provided to the mandrel 13 At the positions α ₁ and α ₂ , a cylindrical cap seal S delivered from the seal supply device 3 is inserted.
[0017]
As shown in FIG. 2B, the mandrel 13 is spaced 2 from each chain element 12a so as to correspond to the confectionery container P conveyed in parallel to the seal insertion position β. The installation intervals of the plurality of mandrels 13 that are attached one by one and that constitute each row are the same as the accommodation intervals of the plurality of confectionery containers P accommodated in the case C that is conveyed to the seal insertion position β. (See FIG. 3A).
[0018]
Each mandrel 13 into which the cap seal S is inserted has an extrusion bar 14 for the cap seal S that protrudes from the outer peripheral surface thereof and fits into a cam groove 15 a formed in a plate 15 installed on both sides of the endless chain 12. The mandrel 13 is movably attached in the protruding direction, and the push bar 14 is guided by the cam groove 15a and moved in the protruding direction of the mandrel 13, so that the cap seal S fitted into the mandrel 13 is inserted. It can be extruded and inserted into the mouth portion of the confectionery container P at the seal insertion position β.
[0019]
This seal fitted device 4, one upper arcuate portion of the sprocket 11a side of the endless chain 12, with the seal supply position alpha ₁ for supplying the cap seal S on one mandrel column is set, the endless chain the other of the upper arcuate portion of the sprocket 11b side of 12, the seal supply position alpha ₂ for supplying cap seal S to the other mandrel row are set, both sprockets 11a of the endless chain 12, the lower side between 11b A seal insertion position β is set in the straight line portion.
[0020]
Further, in the downstream side in the movement direction of the seal supply position alpha ₂ after the mandrel 13 has a guide member 16 which covers the front end portion of the mandrel 13 is installed, when the mandrel 13 is reversed along the other sprocket 11b, The cap seal S fitted into the mandrel 13 at the seal supply positions α ₁ and α ₂ is prevented from dropping off from the mandrel 13.
[0021]
In the seal insertion system 1 configured as described above, first, the cylindrical cap seal S formed by the seal supply device 3 is sequentially fed to the seal supply positions α ₁ and α ₂ by the feed roller 3f, and the seal is inserted. The cap seal S is sequentially inserted into the mandrel 13 conveyed to the supply positions α ₁ and α ₂ . As described above, the seal supply positions α ₁ and α ₂ are set in the arc portion of the endless chain 12, and the distance between the tip portions of the adjacent mandrels 13 is widened. The cap seal S to be inserted does not come into contact with the adjacent mandrel 13 or the cap seal S already inserted into the mandrel 13, and the cap seal S is smoothly and reliably inserted into the target mandrel. At this time, the push-out bar 14 is retracted to the base end side of the mandrel 13, so that the insertion operation of the cap seal S is not hindered.
[0022]
In this way, the mandrel 13 in which the cap seal S is inserted is sequentially transferred to the seal insertion position β by the endless chain 12, and at the same time, the container transfer device 2 takes 20 Two sets of confectionery container groups PG in which the book confectionery containers P are accommodated in series in the case C are sequentially conveyed.
[0023]
At the seal insertion position β, as shown in FIG. 3A, the confectionery container P accommodated in the case C and the mandrel 13 into which the cap seal S is inserted are in a state of facing each other. When the extrusion bar 14 moves to the front end side of the mandrel 13, the cap seal S inserted and inserted into the mandrel 13 is pushed out of the mandrel 13 by the extrusion bar 14 and is fitted into the mouth portion of the confectionery container P facing the mandrel 13. Inserted.
[0024]
At this time, after the cap seal S pushed out from the mandrel 13 is completely inserted into the mouth portion of the confectionery container P, the cap seal S fitted into the next mandrel 13 is not pushed out from the mandrel 13. As shown in FIG. 3A, the cap seal S inserted into the next mandrel 13 is pushed out at the moment when the cap seal S is pushed out from the previous mandrel 13 and inserted into the mouth portion of the confectionery container P. For example, before the cap seal S is completely inserted into the mouth portion of the confectionery container P, the cap seal S is pushed out from the next mandrel 13 one after another. The outer peripheral surfaces of the adjacent cap seals S pushed out from the mandrel 13 are in contact with each other.
[0025]
Thus, the confectionery container P in which the cap seal S is inserted into the mouth portion by the seal insertion device 4 is carried out in a state of being accommodated in the case C. The push bar 14 moved to the distal end side of the mandrel 13 to push out the cap seal S is returned to the base end portion of the mandrel 13 by the cam mechanism described above, and is again conveyed to the seal supply positions α ₁ and α ₂ . Is done.
[0026]
As described above, in the seal insertion device 4, when the cap seal S inserted into the mandrel 13 is pushed out and inserted into the mouth portion of the confectionery container P at the seal insertion position β, the cap seal S is confectionery. Before being completely inserted into the mouth portion of the container P, the cap seal S inserted into the next mandrel 13 is pushed out and started to be inserted into the mouth portion of the next confectionery container P. The cap seal S to be pushed out is fitted into the mouth portion of the confectionery container P while maintaining the state where the outer circumferential surface of the lower end portion is in contact with the outer circumferential surface of the adjacent cap seal S pushed out first. Therefore, as described above, since the plurality of confectionery containers P are conveyed in a state of being accommodated in the case C, almost no gap is formed between the mouth portions of the adjacent confectionery containers P. Even in such a case, the lower end portion of the cap seal S pushed out later does not come into contact with the upper end portion of the adjacent cap seal S pushed out earlier. It can be securely inserted.
[0027]
In addition, although embodiment mentioned above demonstrated the case where cap seal S was inserted by the mouth part of confectionery container P, it is not limited to this, The film insertion apparatus of this invention is a bottle container or PET. The present invention can be applied to a case where a tubular film such as a shrink label is inserted into various insertion objects such as bottles.
[0028]
Moreover, although embodiment mentioned above demonstrated the case where the confectionery container P which is going to insert the cap seal S was conveyed to the seal insertion insertion position (beta) in the state accommodated in the case C in series, it is limited to this. Of course, the film insertion device of the present invention can also be applied to the case where the inserts to be inserted into the tubular film are individually conveyed at predetermined intervals. In particular, it is useful when the conveyance interval of the inserted insert is narrow.
[0029]
In the above-described embodiment, in order to simultaneously insert and insert the cap seal S into the mouth portion of the confectionery container P conveyed in two rows, the seal supply device 2 having two sets of components and the two rows of mandrels. Although the seal insertion device 4 provided with a group is installed, the present invention is not limited to this, and the present invention can also be applied to a case in which insertion objects such as confectionery containers are conveyed in one row. Needless to say, in that case, a seal supply device including a set of components, a seal insertion device including a row of mandrels, and the like may be installed.
[0030]
Further, in the above-described embodiment, the plurality of mandrels 13 are attached to the annular endless chain 12 spanned over the sprockets 11a and 11b arranged at a predetermined interval. However, the present invention is not limited to this. Instead of a sprocket and an endless chain, it is also possible to use a pulley and a timing belt.
[0031]
In the above-described embodiment, the cap seal S pushed out from the mandrel 13 is maintained in a state where the outer peripheral surface of the lower end thereof is in contact with the outer peripheral surface of the adjacent cap seal S that has been pushed out first. However, the present invention is not limited to this, and the lower end portion of the cap seal S pushed out from the mandrel 13 is in contact with the adjacent cap seal S pushed out earlier. The outer peripheral surfaces of the cap seal S are not necessarily in contact with each other as long as they are fitted and inserted into the mouth portion of the confectionery container P while maintaining the state where they overlap each other in the transport direction of the mandrel 13.
