Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass tube processing apparatus, and more particularly to an apparatus for manufacturing containers from glass tubes.

The device has holders that rotate around a common axis and move through several processing steps, with a progressive rotating magazine containing several glass tubes above each holder. is installed, the lower end of each glass tube is on a fixed support plate,
The fixed support plate has a hole for dropping the glass tube, and the device also rotates the magazine one step at a time, i.e. the distance between adjacent glass tubes, to drop the glass tube from the hole. Has a switch. The device described above is known, in which the progressive rotation of the magazine and the loading of the glass tube into the holder are carried out in one working step.

That is, a magazine carries the glass tube over a hole in the support plate, through which the glass tube falls into a holder (DE 1293972). However, this arrangement is not completely satisfactory due to the double operation. That is,
The progressive magazine rotation and dropping of the glass tube into the holder takes a considerable amount of time and limits the operating speed of the equipment.
The object of the present invention is to provide the
It is an object of the present invention to provide a glass processing apparatus as described above, which considerably increases the working speed of the apparatus or allows the apparatus to have a large number of holders.

According to the invention, the problem is that between the hole in each support plate and the holder below it, the magazine can be rotated step by step without the glass tube falling through the hole into the empty holder below, and then the hole is closed. The problem was solved by installing a movable blocking plate that could be used to solve the problem. The device according to the invention has the advantage that the two operations of progressive rotation of the magazine and supply of glass tubes to the holder are carried out independently of each other.

In particular, if necessary, the magazine can be rotated step by step long before the glass tubes are fed into the holders.
Therefore, the entire distance between the two processing steps can be fully utilized for placing the glass tube in the holder. All the glass tubes already in place must be dropped into the holder and this is simply done by releasing the blocking plate supporting the lower end of the glass tube. will be described in more detail with reference to the accompanying drawings.

In FIGS. 1 and 2, a carrier 11 is installed on a support ring 12 and circulates through the processing steps.

The upper end of the carrier 1 1 supports two holders 13, each holder 13 supporting a rotary magazine 14, each rotary magazine 14 being arranged in a circle and accommodating a glass tube 16, as is clear from FIG. It has nine reservoirs 15. Each glass tube 16 rests with its lower end on a support plate 17 fixed on the carrier 11.
Each support plate 17 has a hole 18 in line with the holder 13 so that the glass tube 16 falls into the holder 13. When the glass tube falls, the holder actuating fork 19 moves downward and the holder 13 grasps the upper end of the glass tube 16.

A roller 20 attached to the actuation fork 19 then rotates the switch lever 21 to actuate the switch 22.
This causes pressurized fluid to enter the front part of the cylinder 23, retracting the piston 24, and rotating the lever 25, which has two arms and rotates on a rotating pin 26, counterclockwise.
This moves the two-armed lever 25 to the position shown in FIG.

In this movement the nose 27 of the lever 25 with two arms
Further, the lever 31 having two rotating arms is rotated clockwise using the rotating pin 30 as a ball, and the lever 31 having two arms is rotated against the spring 32. The other arm 29 of the two-armed lever 31 has a notch 28 which can be secured to the position of a magazine pin 33 mounted on the underside of the rotary magazine 14.

Clockwise rotation of the two-armed lever 31 releases the magazine bin 33 from the notch 28.

While the carrier 11 is rotating in the direction of arrow 39 (FIG. 2), the other magazine pin 33' presses against the distal face of the nose 27.

As the carrier 11 moves further clockwise, the magazine 14 is rotated counterclockwise until the nose 27 is again separated from said pin 33'. That is, this is because the nose 27 projects into the passage of another magazine pin 33' in FIG. 33'
When the pin 33' reaches this position, the pin 33' separates from the nose 27 again. When the magazine rotation process is completed, the two two-armed levers are rotated back to their original positions, arms 29 are moved inwardly by springs 32, and notches 28 engage magazine pins 33'. and stick it. Magazine 14
During the rotation process of FIG. The blocking plate 36 closes the hole 18 as shown by the broken line at the top.

The blocking plate 36 rotates on a rotating sleeve 35 containing a sliding rod 38 acted upon by a compression spring 39 .
A lock head 40 is attached to the upper end of the slide rod 38 and engages with a lock groove 41 of the blocking plate 36.
When the rotation process of the magazine 14 is completed, the lower end of one glass tube rests on the upper surface of the blocking plate 36. Empty holder 13
The glass tube is dropped as follows.

As the carrier 11 continues to advance, the roller 20 of the holder actuating fork 19 rotates up on the stationary edge cam 42 which raises the fork 19 to open the holder. The fork 19 pushes up the push-up rod 43, and this push-up pushes up the slide rod 38 against the compression spring 39. This causes the locking head 40 to disengage from the locking groove 41 of the blocking plate 36 and the blocking plate 36 to be quickly pierced by the spring 37, allowing the glass tube to fall through the closure 18 into the empty holder. FIG. 3a shows the first step of the magazine in the position of the parts shown in FIGS. 1 and 2. FIG.

Figure 3b shows the member during stepwise movement. FIG. 3c shows the entrance of the holder by the edge cam 42. It will be observed that the glass tube falls through the holder until the lower end of the glass tube snaps onto the lower support plate 44. 3rd c
In the figure, the holder grasping means 45 is open. As soon as the roller 20 leaves the edge cam 42, the holder actuating fork 19 moves downwards, so that the holder gripping means 45 grips the glass tube 16 as shown in FIG. 3d. In FIG. 2, the magazine 14 has rotated one step and the blocking plate opens quickly when the next machining step arrives.

However, these two steps do not necessarily need to be performed in two consecutive steps. Conversely, rotation of the magazine can be performed at any desired step around the circumference of the device. Next, the embodiment shown in FIGS. 4 to 7 will be described. In FIG. 5, the blocking plate 52 is shown in a position such that the glass tube can pass through the hole 18, such that the locking pin 54 is close to the center of the axis of the magazine 14.

The fixation pin 54 can be moved radially outward from the innermost layer by one of the switch projections 60. During its movement, the fixing pin 54 is guided by a locking groove 57 and a bent groove 58; the locking groove 57 is formed in the blocking plate 52, and the bent groove 58 is formed in the support plate 17. A fixing portion for holding a fixing pin 5'4 is formed at the end of the curved groove 58 of the support plate 17 farthest from the center of the magazine 14. When the holder 13 is not empty, the fixing pin 54 is held in the fixed position by the springs 51 and 55. When the holder 13 is free, the actuating head 65 presses against the end of the lever 25, which, as it rotates clockwise, simultaneously presses the free end of the lever 67 against the pin 54. It is removed from the fixed position in the groove 58. When the pin 54 leaves the fixed position, the spring 51 rotates the blocking plate 52 clockwise and the hole 18 opens. In FIGS. 7a and 7b, the fixing pin 54, the locking groove 57, and the bending groove 58 are shown, and arrows P51 and P55 indicate the forces of the springs 51 and 55 acting on the pin 54. 7a shows the position of the fixing pin 54 when the glass tube falls through the hole 18, while FIG. 7b shows the fixing pin 54 when the blocking plate 52 closes the hole 18. 54 positions are shown. The forces of arrows P51 and P55 prevent anchoring pin 54 from leaving the position shown in Figure 7b. Only after the free end of the lever 67 has moved the anchoring pin 54 inwardly through the position can the anchoring pin 54 be moved further into the position shown in Figure 7a. Once the glass tube has been processed and the upper end of the glass tube is moved below the support plate 17, the magazine can be rotated to any operating step around the circumference of the glass processing device.

The detector 46 detects that the upper end of the glass tube has been lowered below the support plate 17. Detector 46 can, if desired, be a photovoltaic device with a light source 47 as shown in FIG. 6a. If the glass tube is missing, detector 46 activates switch 48 which activates solenoid 49 which retracts piston 50. The piston 50 rotates the two-armed lever 25 counterclockwise, so that the arm 29 rotates clockwise and disengages from the magazine pin, causing the magazine 14 to rotate counterclockwise in one direction.
Process rotation. In this embodiment according to the invention, the magazine 14 has a blocking plate 52 which is acted upon by a return spring 51 and whose center rotates.

The lever 53 rotates on the lower surface of the blocking plate 52, and the lever 53 rotates on the lower surface of the blocking plate 52.
The other end of 3 supports a fixing pin 54, which is connected to an arm 56 of the blocking plate 52 by a spring 55. The fastening pin 54 operates in the locking groove 17 of the arm 66 of the blocking plate 52. Furthermore, the upper end of the fixing pin 54 engages with the curved groove 58 of the support plate 17. A pusher 59 having switch protrusions 60 arranged radially is fixed to the central axis of the magazine 14.

Now, when the magazine 14 is rotated one step, as already described in the apparatus of FIGS. 1-3, one of the switch projections 6
0' moves the anchoring pin 54 counterclockwise and radially outward due to the shape of its switch protrusion 60'.

This is a curved groove 58 held by a spring 55.
The fixing pin 54 is moved to the fixing part. With the fixing pin in this position, the blocking plate 52 blocks the hole 18 as shown in FIGS. 6b-6d. carrier 11
moves further, and the holder 13 approaches the step where the glass tube falls into the holder.

A detector 61 with a light source 62 detects that the holder is empty, as shown in FIG. 6d. Holder grasping means 4
5 is opened by the action of the edge cam 42. The detector 61 closes the switch 63 which activates the solenoid 64.
41, move the operating head 65 forward, and the operating head 65
By rotating the lever 25 having a book arm clockwise and also rotating the lever 67, the end of the lever 67 resists the spring 55 to change the position of the fixing pin 54, and the fixing part of the curved groove 68 of the support plate 17 is moved. Exclude locking pins from. The return spring 51 quickly moves the blocking plate 52 into the open position so that the glass tube 16 falls until its lower end rests on the lower support plate 44 (FIG. 6d). 19 leaves the edge cam 42 and the fork 19 moves downwards to close the holder grasping means and grasp the glass tube (Fig. 6f). Both embodiments of the invention so far described It has the advantage of being able to functionally separate the progressive rotation of the glass tube from the glass tube supply to the holder.

Further, the magazine can be advanced at any processing step on the circumference of the device. This considerably reduces the time required to supply the glass tubes to the holder.
