Abstract

PURPOSE:To improve workability by successively executing a chucking operation to chuck a piece cartridge mounted with a 1st cap to one end of a body plate formed to a cylindrical shape and a mounting operation to mount a 2nd cap on the other end of the body plate in different stations. CONSTITUTION:Respective chucking means 300 circulate between 1st-4th stations A-D positioned at 90 deg. intervals by intermittent rotations of an index plate 201 by an indexing device 202 while the means stop once simultaneously in the respective stations. The 1st station A exists in the position where a movable chuck 302 releases the chucking and where setting of the piece cartridge 1 to a stationary chuck 301 is possible. The chuck 302 turns to the chucking position and the cartridge is chucked after completion of said setting. A head 40 of a tentative fastening means 400 moves from the front direction of the plate 201 when the cartridge 1 is set in the chuck 301. Then, the head comes into contact with the aperture end of the body plate 2 of the cartridge 1 and holds the cartridge 1 to the prescribed position of the chuck 301.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a capping method for attaching a cap to a cartridge, which is an intermediate process product, in the manufacturing process of a cartridge that accommodates a photographic roll film. (Prior Art) In the manufacturing process of cartridges that accommodate photographic roll films, single cartridges are manufactured as intermediate process products. A single cartridge is one in which a cap is attached only to one end of the chest plate formed in a cylindrical shape, and a cap is not yet attached to the other end, and the other end of the single cartridge loaded with film is By attaching a cap to the cartridge (hereinafter referred to as capping), a cartridge containing a film is completed.

As a capping device for mechanically performing capping, the type disclosed in Japanese Patent Publication No. 60-6502 is conventionally known. That is,
The above device chucks one cartridge loaded with a film onto a chucking means fixed at a predetermined position on a substrate, and attaches a cap to the other end of the body of the chucked one cartridge by means of a mounting means. It is made by attaching it.

(Problems to be Solved by the Invention) However, in such a conventional capping 8 position, the chucking operation by the chucking means and the mounting operation by the mounting means are performed at the same location. The chucking operation and mounting operation are performed on one cartridge, and after taking it out, the same operation is performed on the next cartridge, which results in a long cycle time in the capping process, which is an obstacle to improving productivity. It has become. In addition, although the supply of one cartridge to the chucking means is generally performed by a worker, if the chucking operation and the mounting operation are performed at the same location, the worker's hand or fingers may be caught in the mounting means when supplying one cartridge. It is highly dangerous, and improvements from a safety perspective are required.

In particular, recently, cartridges in which the cap is attached by caulking have been developed and produced, and when the attachment operation is performed by caulking, an extremely large force is applied compared to the attachment operation by conventional fitting. Therefore, improving safety is becoming more important. Furthermore, when caulking is used for the mounting operation, the mounting means needs to be a large device, so if the mounting means is located near the chucking means, one cartridge supply to the chucking means (
The work space required for (and removal) becomes narrower, and work efficiency decreases.

The present invention has been made in view of these circumstances, and it is an object of the present invention to provide a capping method and apparatus that can improve productivity, safety, and workability.

(Means for Solving the Problems) The capping method according to the present invention aims to achieve the above object by sequentially performing the chucking operation and the mounting operation at different stations. The capping device according to the invention circulates the plurality of chucking means between the plurality of stations by the intermittent transfer means, so that the chucking operation by the chucking means and the mounting operation by the mounting means can be performed at different stations. This is what I did. That is, the capping method according to the present invention includes a chucking operation of chucking a single cartridge having a first cap attached to one end of a body plate formed in a cylindrical shape; A capping method comprising a mounting operation of mounting a second cap on the other end of the body plate, characterized in that the chucking operation and the mounting operation are sequentially performed at different stations, and the method according to the present invention The capping device includes a plurality of chucking means capable of chucking a cartridge having a first cap attached to one end of a chest plate formed in a cylindrical shape, and a plurality of chucking means capable of chucking each of the chucking means in sequence. an intermittent transfer means that circulates between a plurality of stationary machines including the king station and the mounting station while stopping at the king station and the mounting station; and the other end of the body of the one cartridge chucked by the chucking means stopped at the device station. a mounting means for mounting a second cap on the chucking station, the one cartridge is chucked by the chucking means at the chucking station, and the second cap is mounted on the mounting means at the mounting station. It is characterized by being configured in such a way as to force the user to move.

The chucking part, chucking method, etc. of one cartridge in the above-mentioned chucking operation J must not interfere with the mounting operation that will be performed later.
The method is not limited to this.

The above-mentioned "attachment operation" is not particularly limited as long as the second cap can be attached to the chest plate of one patrone to form a patrone, and can be performed by, for example, caulking, fitting, etc.

The above-mentioned "intermittent transfer means" is limited to a specific transfer structure, as long as it is capable of circulating the plurality of chucking means sequentially between the plurality of stations while temporarily stopping at least at the chucking station and the mounting station. For example, an index-type, packet-type, or other transport structure can be adopted.

The above-mentioned "plurality of stations" may be only a chucking station and a device station, or may include other stations (for example, a chucking release station that releases chucking by a chucking means to take out a cartridge completed by capping). ) may be added. In the case where only the chucking station and the mounting station are used, the cartridge is taken out at the mounting station or the chucking station, or while the chucking means moves from the mounting station to the chucking station.

(Function) With the above configuration, the chucking operation for one batten O-ne and the device operation are sequentially performed at different stations, that is, the chucking station and the mounting station.

(Effects of the Invention) Therefore, according to the present invention, it is possible to perform the device operation for one cartridge and the chucking operation for the other cartridge in parallel, thereby shortening the cycle time in the camping process. It is possible to improve productivity. Also, since no mounting operation is performed at the chucking station,
When supplying one cartridge to the chucking means, there is no risk of hands or fingers being pinched by the mounting means, and safety can be improved. Furthermore, since it is possible to arrange the mounting means at a position away from the chucking station, even if the mounting means is a large device, one cartridge can be supplied to the chucking means (and in some cases, This makes it possible to secure a sufficient working space for the process (removal), thereby improving work efficiency.

The camping device according to the present invention is provided with a temporary fixing means that can temporarily fix one cartridge to a predetermined position of the chucking means, so that the temporary fixing means can be used to temporarily fix one cartridge to a predetermined position of the chucking means at the chucking station. By temporarily fixing one cartridge to a predetermined position of the chucking means using the fixing means, the following effects can be obtained. That is, after supplying one cartridge to the chucking means, until the chunking operation is completed,
Since the operator no longer needs to hold one cartridge in a predetermined position on the chucking means, the operator can move on to the next operation, improving work efficiency and reducing cycle time. In addition, since there is no risk of hands or fingers being caught by the chucking means, safety can be improved.

Embodiments Below, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of essential parts showing an embodiment of a capping device according to the present invention, and FIG. 2 is an overall plan view thereof.

As shown in FIGS. 1 and 2, the capping device includes an intermittent transfer means 200 fixed to a substrate 100, four chucking means 300 disposed on an index plate 201 of this intermittent transfer means 200, and a substrate 100. It is provided with temporary fixing means 400 and mounting means 500 fixed to.

The intermittent transfer means 200 has a rotating shaft 201 extending in the horizontal direction.
A disk-shaped index plate 201 rotatably provided around a and this index plate 201
It is equipped with an index allocation device et202 that rotates in one direction while stopping once every 0 degrees.

The four chucking means 300 are distributed on the same circumference near the outer peripheral edge of the surface of the index plate 201 at intervals of 90 degrees. Each chucking means includes a fixed chuck 30 fixed to the index plate 201.
1, and a movable chuck 302 rotatably supported by the index plate 201 around a fulcrum shaft 302a so as to be able to take a chucking position and a chucking release position. It is now possible to chuck Patrone 1.

The cartridge cartridge 1 has a tab 2a for drawing out the film.
Other than that, it consists of a body plate 2 formed into a cylindrical shape and a first cap 3 attached to one end of this body plate 2. Inside this one-piece cartridge 1 is a film wound around a winding shaft 10. (
(not shown) is loaded. This cartridge 1 is
When the second cap 21 is attached to the other end of the body plate 2 by the capping device shown in this embodiment, a cartridge 20 is obtained.

When the movable chuck 302 is in the chucking position, the fixed chuck 301 and the movable chuck 302 of the chucking means 300 have a partially open cylinder having approximately the same diameter as the body plate 2 of the cartridge cartridge 1 between the two chucks. The shape is such that a space is formed, so that the single cartridge 1 can be reliably chucked. Further, the fixed chuck 301 is provided with a detection rod 303 so as to be able to be suspended from the fixed chuck 301.
When one cartridge 1 is set to 01, the detection rod 303
It is designed to detect that one cartridge 1 has been set by retreating.

Each chucking means 300 has an index allocation of 1ff.
By intermittent rotation of the index plays 1-201 by the ff 202, the index plates 1-201 are circulated among the stations while simultaneously stopping at the first to fourth stations A-D located at 90° intervals.

The first station A is located horizontally to the left of the rotation axis when the index plate 201 is viewed from the front. This first station A is a chucking station where the chucking means 300 performs a chucking operation of the single cartridge 1.

That is, when the chucking means 300 is stopped at the first station A, the movable chuck 302 is in the chucking release position, and the single cartridge 1 can be set on the fixed chuck 301.

After this setting is completed, the movable chuck 302 is rotated to the chucking position and chucking is performed.
If one of the cartridges 1 is held until the movable chuck 302 completes its rotation after setting the cartridge to 1, there is a risk that the movable chuck 302 may get the user's hands or fingers caught, and the operator may have to move on to the next operation. Since I can't do it, I have one cartridge 1.
When the detection rod 303 detects that the index plate 201 is set on the fixed chuck 301, the head 401 of the temporary fixing means 400 moves from the front direction of the index plate 201 and comes into contact with the open end of the body plate 2 of the cartridge cartridge 1, One cartridge 1 is held at a predetermined position on fixed chuck 301 until rotation of movable chuck 302 is completed.

The predetermined position of the fixed chuck 301 is, as is clear from the chucking means 300 at the second station B in FIG. 3, which is a front view of the index plate 201, and the cartridge cartridge 1 chucked thereon.
This refers to the position where the edge portion 301a of the fixing chuck 301 contacts the edge portion 2a of the body plate 2 of the cartridge cartridge 1, and in order to position the cartridge cartridge 1 at this predetermined position, the head 401 of the temporary fixing means 400 not only moves in the axial direction of the index plate 201, but also rotates by a predetermined angle around the axis of the support rod 402 that supports the head 4H.

FIG. 4 is a side view showing the temporary fixing means 400.

The housing 403 of the temporary fixing means 400 is provided with two cylinders 404 and 405. The front and rear driving cylinder 404 moves the head 401 in the axial direction of the support rod 402, and the rotation cylinder 405 moves the head 401.
is rotated around the axis of the support rod 402. Head 401 by front-rear driving cylinder 404
The movement of the output rod 404a of the cylinder 404 is carried out by the front bracket 406, the transmission rod 407 disposed parallel to the support rod 402, and the rear bracket 40.
8 to the support rod 402. Front and rear brackets 406, 408 are adapted to pivotally support support rod 402. The rotation of the head 401 by the rotation cylinder 405 is as follows:
The vertical movement of the output rod 405a of the cylinder 405 is converted into a rotational movement and transmitted through a transmission rod 410 extending parallel to the support rod 402 and a pair of rotation brackets 411, which are urged downward by a coil spring 409. done by doing. As shown in FIG. 5, the head 401 is formed in the shape of a horizontal cylinder with the upper part cut off horizontally and the front end face cut into a cup shape.

FIG. 6 is a perspective view of the first fixing member A showing the action of the temporary fixing means 400.

When the detection rod 303 detects that the cartridge cartridge 1 is set on the fixed chuck 301, the temporary fixing means 4
As already mentioned, the head 401 of 00 comes into contact with the front end of the body plate 20 of one cartridge 1 to hold one cartridge 1 in a predetermined position. Even if the set position on the chuck 301 deviates somewhat from the above-mentioned predetermined position, the rotation of the head 401 ensures accurate positioning at the predetermined position. Therefore, the operator holds one cartridge 1 on the fixing chuck 301.
You don't have to be so nervous when setting it up, which improves work efficiency. The amount of rotation of the head 401 for accurately positioning one cartridge 1 is set in advance by adjusting the amount of rise of the output rod 405a of the rotation cylinder 405.

In addition, in this way, one cartridge 1 is attached to the chucking means 3.
The reason why the operation of positioning the fixed chuck 301 of 00 in the rotational direction is required is to prevent caulking failure from occurring during the subsequent mounting operation.

Although it is possible to perform the above-mentioned positioning in the rotational direction by pressing the one cartridge 1 with the movable chuck 302 when the movable chuck 302 rotates to the chucking position and rotating the one cartridge 1 to a predetermined position, it is possible to do this. This method is unfavorable in terms of quality because the collision of the movable chuck 302 causes deformation or damage to one cartridge 1.

As shown in FIG. 2, in the vicinity of the side of the first station A, a detection means 1O1 consisting of a photoelectric switch or the like is installed on the substrate 10.
0, and when the detection means 101 confirms that the operator has finished setting one of the cartridges 1 and that his/her hand or the like has left the fixed chuck 301, the movable chuck 302 rotates to the chucking position. The chucking operation is completed.

In FIG. 1, the one cartridge 1 chucked by the chucking means 300 at the first station A is transferred to the second station A.
After passing through the station B and stopping at the third station C, the second cap 21 is attached to the open end of the body plate 2.

FIG. 7 shows a mounting means 50 for mounting the cap 21.
It is a side view showing 0.

The mounting means 500 includes a caulking chuck 501 for chucking the open end of the body 2 of the cartridge 1 chucked by the chucking means 300 stopped at a third station C serving as a mounting station, and a caulking chuck 501 that supports the caulking chuck 501. A caulking chuck holder 502 and a cartridge 1 chucked in the caulking chuck 501
The crimping head 503 that crimps the cap 21 onto the open end of the body 2, the crimping chuck holder 502, and the crimping head 503 are respectively attached to the index table 201.
The holder 5 is movably supported in the direction of the rotation axis 201a of the
04, and a cap chute 505 for supplying the cap 21 between the cartridge cartridge 1 and the caulking head 503.

As shown in FIG. 8, the caulking chuck 501 includes a pair of movable chucks 501a and 501 rotatably supported by a caulking chuck holder 502 at a fulcrum shaft 506.
b, consisting of a pair of left and right opening/closing levers 507a and 50
7b for rotation. Each movable chuck 501a, 501b has a substantially semicircular notch 508a.

508b are formed respectively, and both movable chucks 5
When the cartridges 01a and 501b are closed, they can hold the outer circumference of the body plate 2 of the cartridge cartridge 1.

This state is shown in FIG. When the perfectly circular cap 21 is fitted onto the rounded perfectly circular body plate 2, the shaft is moved by the drive of a cam (not shown), and the tip of the claw of the crimping head 503 performs crimping. The body plate and cap are crimped with a zipper.

One cartridge 1 with the cap 21 attached in this way
(i.e. Patrone 20), as shown in FIG.
When the chucking means 300 stops at the fourth station D, the movable chuck 302 rotates to the chucking release position and is ejected downward by its own weight.

The discharged cartridge 20 naturally falls onto the discharge chute 102 shown in FIG. 2, and is sent to the next process. A discharge detector 103 is provided in the discharge chute 102,
It is configured to confirm that the cartridge 20 has been ejected.

Upon confirmation of this ejection, the ejection operation at the fourth station D is completed.

After the ejection is completed, the chucking means 300 stops at the first station A due to the rotation of the index table 201, and then chucks the one cartridge 1 again.

The chucking operation at the first station A, the mounting operation at the third station C, and the discharging operation at the fourth station D are performed at each station A, C, and D simultaneously in synchronization with the temporary stop of the index table 201. Therefore, the chucking means 300
If one cartridge 1 is set on the fixed chuck 301 every time the station A is stopped, the cartridge 20 will be sent out from the fourth station D at intervals of the intermittent rotation of the index table 201.

The timing at which the index table 201 starts rotating after it has stopped once is determined by the last completed operation of the chucking, loading, and discharging operations at the first, third, and fourth stations A, C, and D. When completed. Therefore, if the mounting operation at the third station C takes a long time, the second station B, which did not perform any operation in this embodiment, may be used to share part of the mounting operation. good. For example, it is possible to divide the operation so that the second station B performs an operation of bringing the cap 21 into contact with one cartridge 1, and the third station C performs an operation of caulking the cap 16 against one cartridge 1.

Further, in this embodiment, the cartridge 20 is ejected from the fourth station D, but the ejection of the cartridge 20 does not necessarily have to be synchronized with the temporary stop of the chucking means 300. 1 During the movement to station A, the movable chuck 302 may be rotated to the chucking release position to eject one cartridge 1.
