Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a syringe processing apparatus, and more particularly, to a syringe processing apparatus having a main wheel and a supply wheel for transferring a syringe to the main wheel.

[0002]

2. Description of the Related Art A syringe processing apparatus for transferring a syringe held in a pocket of a supply wheel to a pocket of a main wheel at a predetermined transfer position has been known (Japanese Patent Application Laid-Open No. Hei 7-156996). In such a conventional device, the two wheels are configured to rotate continuously in synchronization with each other, and the main wheel on the side where the syringe has been delivered to the pocket at the delivery position receives the respective wheels during the subsequent continuous rotation. The syringe held in the pocket is configured to be subjected to processing such as filling with a drug solution.

[0003]

Incidentally, as a function of a main wheel which receives a syringe and performs a required process on the syringe, there is a case where a configuration capable of processing a plurality of syringes at once is desired. For example, there may be a demand for a configuration in which four successive syringes held in pockets are simultaneously filled with a filling liquid. To meet such demands, it is necessary to intermittently rotate the main wheel for every four pockets, but such a configuration causes the following problem. That is, at the transfer position, the syringes are simultaneously held by the pockets of both wheels. Therefore, when the supply wheel is rotated in a state where the main wheel is intermittently rotated in units of a plurality of pockets and temporarily stopped, the syringe located at the delivery position is damaged by the pocket of the supply wheel. Therefore, in such a configuration, it is necessary to temporarily stop the other supply wheel while the main wheel is temporarily stopped. In other words, in a configuration in which the main wheel is intermittently rotated in units of a plurality of pockets, there is a disadvantage that the supply wheel cannot be rotated while the main wheel is temporarily stopped. Japanese Patent Application Laid-Open No. Hei 7-257745 discloses a syringe processing device that transfers a syringe from one wheel that rotates continuously to another wheel that rotates intermittently.
A gazette is known. However, in the device of this publication, one of the wheels that rotates intermittently rotates intermittently at every pitch of the pocket, and does not rotate intermittently in units of a plurality of pockets.

[0004]

[Means for Solving the Problems] In view of such circumstances,
The present invention has a large number of pockets provided at a constant pitch in the circumferential direction to hold a syringe, and among the large number of pockets, the same number and a plurality of successive pockets are paired to form the large number of pockets. Dividing the pockets into a plurality of sets, a main wheel intermittently rotating for each set of the pockets, and a plurality of the same pitches as the pitch and provided at least as many as the set of the pockets and holding a syringe. A supply wheel having a pocket; and a syringe supply means for supplying a syringe to the pocket when the supply wheel rotates. When the main wheel is temporarily stopped, the supply wheel is rotated at every one pitch. It is configured to rotate intermittently to supply a syringe from the syringe supply means to the pocket,
The supply wheel holding the syringe in the pocket is configured to rotate to a position before a predetermined delivery position and then stop when the main wheel is temporarily stopped. When the intermittent rotation is performed for each of the pockets, the supply wheel is also rotated by at least the one set of pockets in synchronization with the rotation operation, and the set of syringes held in the pockets of the supply wheel is transferred to the delivery position. The present invention provides a syringe processing device that is configured to be sequentially delivered to pockets of a main wheel.

[0005]

According to the above-described configuration, for example, when the main wheel rotates intermittently and temporarily stops, the syringe is not held in the pockets of the two wheels located at the transfer position. The supply wheel can rotate while the wheel is stationary. Thus, the main wheel can rotate intermittently for each set of pockets, and the supply wheel can rotate while the main wheel is paused.

[0006]

Pockets 4a and 5a for holding the syringe 2 in accordance with the pitch are provided. When the main wheel 3 is intermittently rotated clockwise, the supply wheel 4 and the discharge wheel 5 are rotated counterclockwise in synchronization with the rotation. Thereby, at the transfer position A, each pocket 3a of the main wheel 3
The syringe 2 is supplied from the pocket 4 a of the supply wheel 4. In the discharge position E,
Pocket 3 of main wheel 3 by discharge wheel 5
The syringe 2 is discharged from a. The syringe 2 is transported while being held in each of the pockets 3a, 4a, 5a such that the flange 2b is at the upper end and the distal end 2a is at the lower end (see FIG. 3). As will be described later in detail, the supply wheel 4
Pockets 4a to main wheel 3 pockets 3a
As shown in FIG. 12, a cap 6 is attached to the distal end opening 2 of the syringe 2 supplied to the tip 2 in advance by a stopper mechanism on the supply wheel 4 side (see FIG. 12).

The main wheel 3 is composed of four successive pockets 3a as a set, and the four pockets 3a
It is configured to intermittently rotate clockwise each time. When the four syringes 2 held in one set of four pockets 3a are temporarily stopped in the predetermined filling zone C in the process of intermittently rotating the main wheel 3, the filling zone C The four syringes 2 are configured to be simultaneously filled with a chemical solution by a filling nozzle (not shown) provided in (1) (see FIG. 13). After this,
The four syringes 2 filled with the chemical solution are further provided with a stopper mechanism (not shown) provided in the stopper zone D when the main wheel 3 is temporarily stopped in the stopper zone D as the main wheel 3 rotates intermittently. The sealing member 7 is fitted to the upper opening by
Thereby, the upper opening is sealed (see FIG. 14). Thereafter, the syringe 2 fitted with the seal member 7 is configured to be sequentially discharged by the discharge wheel 5 from each pocket 3a of the main wheel 3 at the discharge position E with the intermittent rotation of the main wheel 3. I have. As described above, the main wheel 3 of the present embodiment is configured to intermittently rotate for each set of four pockets 3a, and the main wheel 3 held in each pocket 3a with the intermittent rotation. The operation of filling the syringes with the chemical solution is performed, and then the sealing members 7 are inserted into the upper end openings of the four syringes 2.
It is configured to plug. In the present embodiment, the main wheel 3 that is intermittently rotated as described above is used.
The syringe 2 is configured to be smoothly supplied from the supply wheel 4 side to each pocket 3a of the main wheel 3 at the transfer position A in accordance with the operation of.

That is, as shown in FIGS. 1 to 3,
The supply wheel 4 is provided with a rotating plate 8 having a fan shape instead of a circular shape. The rotating plate 8 has a pivotal portion of the fan mounted horizontally on the upper end of a cylindrical rotating shaft 11. Thus, the rotating plate 8 can rotate around the axis B of the rotating shaft 11 as a center of rotation. As shown in FIG. 1, four pockets 4 are formed on the arc-shaped outer peripheral portion of the rotating plate 8 in accordance with the pitch of the pockets 3 a on the main wheel 3 side.
a. The respective syringes 2 are suspended and held by these pockets 4a so that the collar 2b is at the upper end and the tip opening 2a is at the lower end. As shown in FIG. 6, a disk-shaped support member 12 is horizontally connected to an outer peripheral portion below the rotating shaft 11. A cylindrical member 14 is connected to the frame 13 in the vertical direction.
The lower peripheral portion of the rotary shaft 11 is inserted into the cylindrical member 14, and the rotary shaft 11 and the support member 12 are rotatably supported by a pair of upper and lower bearings 15. The bottom of the support member 12 is slidably mounted on the upper end of the cylindrical member 14, and an annular gear 16 is attached to the outer periphery of the bottom of the support member 12. The gear 16 meshes with a gear 17 on the drive motor side (not shown). Therefore, when the drive motor is rotated, the rotating plate 8 and the supporting member 12 provided on the rotating shaft 11 rotate around the axis B of the rotating shaft 11 as a rotation center. As shown in FIGS. 1 and 7, a syringe chute 22 is provided in a radial direction of the rotating plate 8 at a predetermined position close to the movement trajectory of the pocket 4a when the rotating plate 8 is rotated. The syringe chute 22 is composed of a pair of left and right plate-like members 22A spaced apart from each other by a predetermined distance in the horizontal direction.
The side is gradually reduced in height. The height of the tip portion 22a is set to the same height as the upper surface of the rotating plate 8 (upper end of the pocket 4a). The syringe 2 is inserted between the pair of left and right plate-like members 22A, and slides toward the distal end portion 22a of the syringe chute 22 with the brim portion b placed on the plate-like members 22A. Is configured.

As shown in FIG. 7, an engagement screw 23 is provided at a position below the distal end portion 22a of the syringe chute 22 along the longitudinal direction of the syringe chute 22.
Is rotatably provided. The engagement screw 23 is configured to rotate in a predetermined direction when a drive motor (not shown) is driven. Thereby, the syringe chute 22
The syringe 2 that slides toward the distal end portion 22a is engaged with the thread of the engagement screw 23, so that the successive syringes 2 are separated from each other. The pitch of the thread of the engagement screw 23 is set to be larger as it is closer to the distal end portion 22 a of the syringe chute 22. Therefore, the interval between the leading syringe 2 that is engaged with the engaging screw 23 and located at the distal end portion 22a of the syringe chute 22 and the subsequent second syringe 2 is maintained at a constant interval. The drive motor (not shown) interlocked with the engagement screw 23 is configured such that the pocket 4 a of the rotary plate 8
The engagement screw 23 is rotated at the timing of moving to 2a. Therefore, when the rotating plate 8 is intermittently rotated by one pitch in the rotation region before and after the distal end portion 22 a of the syringe chute 22, the subsequent pockets 3 a from the leading pocket 3 a in the rotation direction are sequentially moved from the syringe chute 22. When temporarily stopping at the position of the distal end portion 22a, the syringe 2 is sequentially supplied to those pockets 3a. The leading pocket 4a in the rotation direction and the pockets 4a at the second and third positions are provided with a semicircular recess 8a provided on the outer peripheral portion of the rotating plate 8, and a recess 8a.
and a semicircular concave portion at the tip of the plate-like member 24 supported below “a”. As a result, the syringe chute 22 is inserted into the pocket 4a at the head and the second and third positions.
Is engaged with a semicircular concave portion 8a provided in the rotary plate 8 and the rotary plate 8 serving as an upper end edge thereof.
The collar portion 2b is placed on the upper surface of the plate member 24, and the outer peripheral portion on the lower side is engaged with the concave portion of the plate member 24.

On the other hand, in FIG. 1, the rearmost pocket 4a in the rotational direction located at the tip end 22a of the syringe chute 22 is the other three pockets 4a described above.
It has a different configuration. That is, FIG.
As shown in FIG. 7, the position of the rear end of the arc-shaped outer peripheral portion of the rotating plate 8 is notched to form a concave portion 8a 'that forms a quarter arc of a circle. A support shaft 25 is connected to the bottom of the rotating plate 8 close to the concave portion 8a 'by a bracket in a vertical direction. The central portions of a pair of upper and lower plate-like members 27 each having a U-shape are fitted to the upper and lower ends of the rod-like member 26, and the through holes 27a provided on the inner sides of the two plate-like members 27 in this state are supported by the support members. The shaft 25 is rotatably fitted. Since the upper plate-like member 27 is placed on the bracket on the side of the rotating plate 8, both plate-like members 27 are maintained at a predetermined height, and the upper plate-like member 27 is
It is located at the same height as the rotating plate 8 and at the rear side in the rotating direction adjacent to the concave portion 8a '. A concave portion 27b formed of a quarter arc of a circle is formed at a position of the upper plate-like member 27 facing the concave portion 8a '.
The lower plate-like member 27 also has a concave portion 27b similar to the upper one. One end of a lever 28 is connected to the outer periphery of the rod-shaped member 26, and a through hole formed in the center of the lever 28 is rotatably fitted to the support shaft 25. Then, a tension spring 31 is attached to the other end of the lever 28 and the rotating plate 8. Thus, the two plate-like members 27 are constantly urged counterclockwise about the support shaft 25 as the center of rotation. Therefore, the end surface of the upper plate member 27 on the side where the concave portion 27b is provided abuts against the end surface 8B on the rear side of the rotating plate 8 facing the end surface (FIG. 4). In this state, the concave portion 8a 'on the rotary plate 8 side and the concave portion 27b of the upper plate-like member 27 are
And a semicircular recess is formed by them. The semicircular recess and the lower plate-like member 27
Constitute the rearmost pocket 4a in the rotational direction.

The four pockets 4a provided on the rotary plate 8 are configured as described above, and the rotary plate 8 intermittently rotates by one pitch provided with the syringe 4a in the area before and after the syringe chute 22. With this, the syringe 2 is supplied to and held in each pocket 4a. Then, when the syringe 2 is held in the rearmost pocket 4a, the rotating plate 8 rotates to the position where the end face 8A on the front side in the rotation direction is indicated by the imaginary line in FIG. It is configured to be. An arc-shaped guide (not shown) is provided along the movement trajectory of the syringe 2 from the position of the distal end portion 22a of the syringe chute 22 to a position slightly before the transfer position A in a counterclockwise direction. The syringe 2 held from is prevented from falling off. When the main wheel 3 is temporarily stopped, the rotating plate 8 that is stopped in the standby state described above is stopped as it is and is in a standby state, but the main wheel 3 has four pockets 3a for one set. When rotated by the amount, the rotating plate 8 is also rotated counterclockwise in synchronization with the rotation. Accordingly, the syringe 2 held in each pocket 4a of the rotating plate 8 is sequentially delivered to the pocket 3a of the main wheel 3 at the delivery position A. When the main wheel 3 rotates by the amount corresponding to the four pockets 3a for one set, the main wheel 3 stops temporarily. Therefore, the fourth syringe 2 supplied to the main wheel 3 at the transfer position A is placed in the pocket 3a of the main wheel 3. At the same time as being held, it is held in the rearmost pocket 4a on the supply wheel 4 side.

Since the rearmost pocket 4a in the rotation direction on the supply wheel 4 side is configured as described above, the upper and lower plate-like members 27 are moved rearward in the rotation direction of the supply wheel 4 at the transfer position A. Side, the rearmost pocket 4a in the rotation direction does not interfere with the syringe 2 stopped at the transfer position A, and the supply wheel 4
Can be rotated. That is, as shown in FIG. 4, a wedge-shaped fixed cam 32 is provided at a position lower than the rotating plate 8 of the supply wheel 4, and at a delivery position A and before and after the delivery position A. On the other hand, as shown in FIG. 5, an annular cam follower 33 is fitted around the outer periphery of the rod-shaped member 26 to which the plate-shaped member 27 is connected. Accordingly, when the supply wheel 4 (rotary plate 8) is continuously rotated after the main wheel 3 is temporarily stopped, the cam follower 33 engages with the cam surface of the fixed cam 32 with the rotation. .
Therefore, the upper and lower plate members 27 are opposed to the tension spring 31.
Is forcibly pushed back toward the rear side in the rotation direction of the rotating plate 8. Thereby, the concave portions 27b of the two plate-like members 27 engaged with the outer peripheral portion of the syringe 2 stopped at the transfer position A
Is separated from the syringe 2, so that, with the rotation of the rotary plate 8, the recesses 27 b of the two plate-shaped members 27 pass through the transfer position A without abutting on the syringe 2 at the transfer position A. Thus, the recesses 2 of the two plate-like members 27
By forcibly separating the syringe 2 from the delivery position 7b, the supply wheel 4 can be continuously rotated even after the main wheel 3 is temporarily stopped.

As shown in FIG. 2, a band-shaped fixed guide 30 is provided along the outer peripheral portion of the main wheel 3, and when the main wheel 3 rotates, its pocket 3
This prevents the syringe 2 from dropping out of a. In the present embodiment, the distal end 30a of the fixed guide 30 is extended to the transfer position A. This allows
The syringe 2 sequentially transferred from the pocket 4a of the supply wheel 4 to the pocket 3a of the main wheel 3 at the transfer position A is also inserted between the pocket 3a of the main wheel 3 and the fixed guide 30 at the transfer position A. ing. Therefore, even at the transfer position A, even if the rearmost pocket 4a of the supply wheel 4 is separated from the syringe 2 at the transfer position A where the supply wheel 4 is stopped, the syringe 2 is still positioned between the pocket 3a of the main wheel 3 and the fixed guide 30. The syringe 2 is held by the distal end 30a, so that the syringe 2 does not fall out of the pocket 3a of the main wheel 3 at the transfer position A. On the other hand, as described above, since the four syringes 2 are continuously supplied to the main wheel 3 at the transfer position A, the rotating plate 8 in which the pockets 4a are emptied is thereafter provided with the pockets 4a. Since the syringe 2 is intermittently rotated by the pitch, the syringe 2 is supplied to each pocket 4a again at the position of the syringe chute 22. In this way, the supply wheel 4 holds the syringe 2 in the four pockets 4a by sequentially passing through the distal end portion 22a of the syringe chute 22, and then rotates to a position just before the transfer position A and then temporarily stops. And it goes into a standby state. When the main wheel 3 is further rotated by a predetermined amount from the stop state, the syringe 2 is rotated in synchronization with the rotation and transferred to the pocket 3a of the main wheel 3 at the transfer position A and held in the four pockets 4a. Supply wheel 4 even if main wheel 3 is paused
Is configured to continuously rotate, and then intermittently rotate by one pitch before and after the distal end portion 22a of the syringe chute 22 again.

Next, as described above, the supply wheel 4 of this embodiment also has a stoppering function for attaching the cap 6 to the distal end portion 2a of the syringe 2, which will be described below. That is, as shown in FIGS. 3 and 6, a cylindrical guide 34 is vertically connected to the support member 12 below the pockets 4a. The shaft 35 is slidably penetrated from above. A block-shaped housing 36 is connected to the upper end of the elevating shaft 35.
A holding part 37 for holding the cap 6 by suction is formed on the upper surface of the head 6. The holding portion 37 is formed of a U-shaped recess formed on the upper surface of the housing 36. This holding part 37
Is connected to a negative pressure source (not shown) via a passage 38 provided in the housing 36, a conduit 41 connected thereto, and a pipe 42 connected to the passage 38 and penetrating through the rotary shaft 11. Therefore, a negative pressure is always introduced into the holding section 37, and when the cap 6 is supplied to the holding section 37, the cap 6 is sucked and held by the negative pressure. further,
An annular centering member 43 is horizontally provided on the housing 36 at a position close to and above the holding portion 37 via a bracket. Center of centering member 43 and holding part 3
7, the center of the centering member 43 and the syringe 2 held in the pocket 4a.
Are configured to be coincident with the axis of. In the rotation section of the rotating plate 8 from the transfer position A to the passing of the syringe chute 22 from the transfer position A, the elevating shaft 35 is located at the descending end position as shown on the left side of the center line in FIG. doing. On the other hand, in a rotation section in which the rotating plate 8 passes through the syringe chute 22 and moves to a position where the rotating plate 8 enters a standby state, the elevating shaft 35 is moved up and down by a predetermined amount by a cam mechanism described later. It has become. When the elevating shaft 35 is located at the lower end, the centering member 43 is located at a position close to and below the distal end 2a (lower end) of the syringe 2 held by the pocket 4a.

As shown in FIGS. 1 and 6, the rotation section of the rotary plate 8 from the transfer position A to the passage through the syringe chute 22 is only one pitch from the tip 22a of the syringe chute 22 to the pocket 4a. A cap chute 44 for supplying the cap 6 to each of the holding portions 37 is provided at a position on the upstream side. As shown in FIGS. 8 and 9, the cap chute 44 is supported horizontally,
The distal end portion 44a is configured to be close to the outer peripheral portion of each housing 36 connected to the elevating shaft 35. The cap chute 44 is configured to be vibrated by a driving mechanism (not shown), so that each cap 6 moves toward the distal end portion 44a in a state in which the openings are vertically aligned in a line. I have. In this embodiment,
The leading end of the stopper 45 that can be swung causes the leading cap 6 located at the leading end 44 a of the cap chute 44 to move.
Is prevented from falling off, and when each housing 36 is moved to the position of the distal end portion 44a of the cap chute 44, the stopper 45 is retracted, so that each holding portion 37 is moved from the distal end portion 44a of the cap chute 44. The cap 6 is supplied. More specifically,
Below the distal end portion 44a of the cap chute 44, a support shaft 47 is rotatably supported in a vertical direction on a bracket 46 connected to a fixed frame. The stopper 45 is horizontally connected to the upper end of the support shaft 47.
A lever 48 is horizontally connected to the lower end of 7. The height of the stopper 45 is set at the tip 44 of the cap chute 44.
The height is adjusted so as to be the same as the height of the cap 6 located at a.

On the other hand, a tension spring 51 is attached between the lever 48 and the bracket 46, and the stopper 45 is urged by the tension spring 51 to rotate clockwise in FIG. The lever 48 is connected to the tip of an air cylinder 52 provided on the bracket 46. When the air cylinder 52 is not operated, the tip of the stopper 45 is engaged with the cap 6 of the tip portion 44a of the cap chute 44 by the tension spring 51. In this state, the top cap 6
From the tip 44a of the cap chute 44 to the holding portion 3
It cannot be supplied to the 7 side. On the contrary,
When the air cylinder 52 is actuated, the stopper 45 is pushed back to the position shown by the imaginary line against the tension spring 51 (FIG. 8).
4 is spaced apart from the cap 6 located at the tip 44a.
Therefore, in this state, the cap chute 44
The top cap 6 located at the front end portion 44a of the
7 is supplied. The air cylinder 52 is operated immediately before each holding portion 37 moves to the position of the tip end portion 44a of the cap chute 44, so that the rotating plate 8 is intermittently rotated. When the respective holding portions 37 are sequentially positioned at the position of the tip portion 44a of the cap chute 44, the cap 6 is supplied to the respective holding portions 37 from the tip portion 44a of the cap chute 44. Then, the cap 6 supplied to each holding portion 37 is
The suction is held by the negative pressure introduced into each holding portion 37 with the opening facing upward.

Next, a description will be given of a cam mechanism for raising and lowering each of the holding portions 37 (elevation shaft 35). As shown in FIG.
A cam follower 53 is rotatably provided on a lower outer peripheral portion of each elevating shaft 35. On the other hand, the tapping zone F extends from a position below the movement trajectory of the cam follower 53 and from a position past the distal end of the syringe chute 22 in the rotation area of the rotary plate 8 to a position slightly before the above-mentioned standby state.
, A cam member 54 is provided. When the rotating plate 8 is rotated, the cam follower 53 of the elevating shaft 35 rolls on the cam member 54 and moves up and down along the cam surface. As shown in FIG. 10, the cam surface of the cam follower 53 gradually increases to the maximum height, and then the height is slightly lowered by making a depression at the center position in the longitudinal direction.
Then, after maintaining the maximum height again, it is gradually lowered. An arc-shaped cam member 55 is disposed above the central portion of the recess in the longitudinal direction along the arc of the recess. Accordingly, in the region where the cam member 55 is provided, the cam follower 53 is simultaneously engaged with the cam surface of the cam member 55 and the cam surface of the lower cam member 54 to move up and down (FIG. 10). When the lift shaft 35 is raised by the cam follower 53 and the cam member 54, the centering member 43 and the holding portion 37 are raised, so that the syringe 2 held in the pocket 4a is lifted.
The centering member 43 is fitted to the distal end portion 2a (lower end) and the upper outer peripheral portion thereof from below. This allows
After the center of the distal end 2a of the syringe 2 and the center of the cap 6 held by the holding portion 37 are aligned, the distal end 2
a.

In this embodiment, a holding plate 56 is provided on the upper surface of the rotating plate 8 in close proximity to each pocket 4a (rotating plate 8). Therefore, even if the cap 6 that is raised as described above is fitted into the distal end opening 2a of the syringe, and the entire syringe 2 is to be lifted upward from the pocket 4a, the flange 2b of the syringe 2 is pressed by the holding plate 56. , The syringe 2 is prevented from being pushed up relative to the pocket. Therefore, with the syringe 2 held in the pocket 4a, the cap 6 is attached to the distal end portion 2a with the rise of the cap 6. As described above, since the cam member 54 is provided with a recess at the center in the longitudinal direction and another cam member 55 is provided above the center, the cap 6 is attached to the distal end portion 2a. Later, the cap 6 attached to the syringe 2 and the holding portion 37 are separated smoothly. Then, at a position past the position of the cam member 55, the cam member 5
4 raises the holding portion 37 again, thereby pushing up the cap 6 twice toward the distal end opening portion 2a of the syringe 2 to thereby move the cap 6 into the syringe 2
So that it can be securely attached to the tip opening. In this manner, when the cap 6 is attached to the distal end opening 2a of the syringe 2, when the syringe 2 moves to the position of the rear end of the cam member 54 with the rotation of the rotary plate 8, each of the vertical movements follows the cam surface. The shaft 35 descends to the descending end position. As a result, the centering member 43 is located below the distal end portion 2a, which is the lower end of the syringe 2.

(Description of Operation of Supply Wheel 4) The operation of the supply wheel 4 based on the above configuration will be described. Here, for the sake of explanation, from the state where the main wheel 3 is temporarily stopped and the rotary plate 8 has passed the transfer position A, the rotary plate 8 after passing the transfer position A is placed in each pocket 4a. Does not hold syringe 2. When the rearmost pocket 4 a of the rotating plate 8 is located at the transfer position A, the foremost pocket 4 a is located at the tip 44 a of the cap chute 44. From this state,
Since the rotating plate 8 is intermittently rotated in units of one pitch provided with the pockets 4a, the caps 6 are sequentially supplied from the tip of the cap chute 44 to each holding portion 37 provided below each pocket 4a with the intermittent rotation. (See FIGS. 1, 8, and 9). Further, with the intermittent rotation of the rotating plate 8 for each pitch, each pocket 4a is temporarily stopped at the position of the tip 22a of the syringe chute 22, so that the syringe 2 is sequentially transferred from the tip 22a of the syringe chute 22 to each pocket 4a. Are sequentially supplied (FIGS. 1, 3, and 7). As a result, the syringe 2 is inserted into the four pockets 4a of the rotating plate 8.
Are supplied, and the cap 6 is held by the holding portion 37 below them (FIG. 7). Thereafter, the rotating plate 8 is further rotated and stopped from the position shown by the solid line in FIG. 1 to the standby position shown by the imaginary line on the end face 8A of the rotating plate 8. During the movement of the rotary plate 8, each holding portion 37 is moved up and down by the cam member 54, so that the cap 6 is fitted to the distal end opening 2 a of each syringe 2 held in the pocket 4 a of the rotary plate 8. . The operation so far is performed while the main wheel 3 is temporarily stopped. When the main wheel 3 is rotated clockwise by a set of four pockets 4a from the standby state of the supply wheel 4 (rotary plate 8), the rotary plate 8 is rotated in synchronization with the rotation. At A, the syringes 2 held in the respective pockets 4a of the supply wheel 4 (rotary plate 8) are sequentially transferred to the pockets 3a of the main wheel 3. Each syringe 2 held in the pocket 3a of the main wheel 3 has a cap 6 attached to the tip end 2a.

The main wheel 3 is temporarily stopped when it is rotated by a set of four pockets 4a, but the supply wheel 4 is continuously rotated thereafter. Here, as shown in FIGS. 2, 4 and 5, the rearmost pocket 4a in the rotation direction of the supply wheel 4 is
As the cam follower 33 engages with the fixed cam 32 with the rotation of the plate 2, the plate-like member 27 swings rearward in the rotation direction with respect to the syringe 2 stopped at the transfer position A, and separates from the syringe 2. . Therefore, this transfer position A
The supply wheel 4 can be rotated without damaging the syringe 2 by the plate-like member 27 constituting the rearmost pocket 4a. Thereafter, the supply wheel 4 repeats the above-described intermittent rotation for each pitch, rotation and stop to the standby position, and further, rotation in synchronization with the main wheel 3 to repeat the syringe with the cap 6 attached to the tip end 2a. 2 is transferred to the main wheel 3. According to the present embodiment described above, the main wheel 3
It can rotate intermittently every four pairs of pockets 3a, and the main wheel 3 stops and the transfer position A
Supply wheel 4 even if the syringe 2 exists in the
Can be rotated.

In the above-described embodiment, among the pockets 4a provided in the supply wheel 4, the rearmost pocket 4a in the rotational direction is configured such that the plate-like member 27 constituting the pocket 4a swings at the transfer position A. However, the rearmost pocket 4a in the rotation direction is
Even if it is composed of a semicircular recess as in a,
The effects described above can be obtained. That is, in the above embodiment, the syringe 2 is not held in the last pocket 4a of the four pockets 4a of the supply wheel 4, and the last of the four pockets 3a of the set on the main wheel 3 side. The syringe 2 should not be held in the pocket 3a at the position of. With this configuration, when the main wheel 3 is rotated and temporarily stopped, the syringe 2 is not held in the pockets 3a and 4a of the two wheels 3 located at the transfer position A. When the wheel 3 is stopped, the supply wheel 4 can be rotated. Furthermore, in this embodiment, the supply wheel 4 also has a function of attaching the cap 6 to the distal end 2a of the syringe 2 held in the pocket 4a.
The installation space of the syringe processing device 1 can be reduced as compared with a case where a device for attaching the cap 6 to the distal end opening 2a of the syringe 2 is separately provided.
