Abstract

The invention is intended for use primarily in single piece dispensing devices that are used in assembling pens. Simplification and increase of reliability in the device, in which the hopper and the tool for dispensing parts, made with an actuator, is achieved by the fact that the tool for dispensing parts is made in the form of a tray mounted movably on a hinge under the hopper and provided with an emphasis for holding the parts mounted on the free the end of the tray above the receiver parts with the ability to cut them one piece at the free end of the tray. In addition, the free end of the tray is provided with a lid and is made with a spring element of the corner profile, and the drive is made with a pneumatic cylinder. 2 hp f-ly, 2 ill.

Description

This invention relates to devices for dispensing parts and is intended primarily for the assembly of ballpoint, capillary and other pens.

The purpose of the invention is to simplify the design and increase reliability.

Fig. 1 shows the automatic machine for assembling pens, a general view; in fig. 2 is a device for routinely feeding parts in a machine for assembling pens.

The handle assembly machine (Fig. 1) consists of a body 1, a transporting drum 2 with longitudinal grooves 3 for accommodating the handles cases, a hopper 4 for loading the handles cases, a hopper 5 for wicks, a receiver 6 for wicks, a hopper 7 for plugs, a pneumatic cylinder 8, a spool 9 with control electromagnets 10 and 11, pipelines 12 and 13 connecting the pneumatic cylinder with the spool, containers 14 for finished handles, driving a transporting drum, for example, a stepper motor (not shown in FIG. 1), devices for single output of parts (Fig. 2). Shells 15 handles from the hopper 4 served

Into the grooves 3 of the transporting drum Detal (wicks) 16 from the bung, "fa 5 is fed to the receiver 6" The automat is connected to the pneumatic circuit through a stop valve 17.

The device for single-piece dispensing of parts includes a tray 18 mounted obliquely under the hopper 5, a pneumatic cylinder 19, a spool 20 with control electromagnets 2i and 22, an emphasis 23, a cover 24 on the free end of the tray, made with an angle profile element 25 attached to it. The pneumatic cylinder 19 is connected by pipelines 26 and 27 to the spool 20, which is connected to the pneumatic network through a shut-off valve 28.

The free end of the tray is connected with the rod of the pneumatic cylinder 19 by the hinge 29. The pneumatic cylinder 19 is movably connected to the body of the machine by the hinge 30. It is possible to install the hinge 31 in the center of the hopper 5. At the same time, the tray 18 works as a double-arm lever, which increases the turning and movement of parts on the tray. Buffer 32 is installed at the bottom of tray 16. Bunker 5 is somewhat wider than tray 18, and the last one is when k (L

can be moved inside the bunker 5

The order of operation is next The hulls of the 15 handles from the hopper 4 are fed directly into the longitudinal grooves 3 of the transporting drum 2, making a turn of 60 °. In six steps, the transporting drum 2 makes one turn, which allows a maximum of six assembly operations, including the operation of feeding The handle bodies 15 into the groove of the conveying drum 2 After the first housing 15 of the handles are fed into the groove 3 of the transporting drum 2, the latter takes one step through 60 ° and stops. In this case, the groove 3 of the drum with the handle body 15 is installed coaxially with the receiver 6. where from the bunker G; .1ut wick lb

On command from the control unit (not shown in Fig. 2), an electromagnet 10 is activated, which moves the valve distributor 9 to the right position and opens a channel for air to enter the pipeline 12. knobs After completing the operation, the control unit receives a signal to the electromagnet 11, which moves the spool 9 to the left position and opens the channel for entering the pipeline 13, as a result of which the pneumatic cylinder piston roars back and back to starting position

Then the transporting drum 2 performs the next mai at 60 ° and again stops with. The following operations are performed, the wick is pushed in the body of the handle and inserted into the body of the handle of the stopper supplied by the Hi hopper. 7 The insertion of the stopper is performed using a pneumatic cylinder (not shown) just as the wick is inserted. As the transport drum rotates further turns, other operations are performed. on the assembly of the pen (filling the wick with ink, inserting a writing tip). The finished handle is dropped into the container 14 located under the transporting drum. When a signal is sent from the control unit to the electromagnet 21, the latter moves the valve 20 to the position where air enters the pipeline 26 and the piston of the pneumatic cylinder 19 moves upwards, the wicks compartment 16 is located on the chute 18, from the wick placed in the receiver 6 (Fig. 2). The piston is in the upper position before performing the operation of pushing the wick into the body of the handle using the pneumatic cylinder 8 (Fig. 1).

the drum is fed from the control unit to the electromagnet 22, which switches the valve 20, and the compressed air enters the pipeline 27. The piston of the pneumatic cylinder moves downwards and carries the free end of the tray until it stops in the buffer 32. When shaken, the end piece rolls into the receiver 6. Then another signal is sent to the electromagnet 21 The spool 20 is switched, the piston of the pneumatic cylinder 19 moves up, the parts are cut off in this way, i.e. the cycle repeats.

A cover 24 installed at the free end prevents parts from being ejected from the tray when it is rocked. A corner spring element 25 mounted on the lid 24 prevents the parts from rolling out when the tray is in its lowest position. When the tray is rocked, there is a slight displacement of parts along the tray. This contributes to their entry from the bunker and ordering when moving to the place of supply to the receiver 6 and the cutoff.

A similar device for the delivery of parts is used for issuing plugs for handles from the hopper 7. In this case, the bunker 7 is equipped with an orientation mechanism for the plugs of known construction. The same device is used to feed the handle bodies to the conveying drum 2.
