Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a conveyor for transporting molded polystyrene foam products, and particularly to a conveyor for feeding molded products to automatic packaging machines and automatic bundling machines. It is.

[Prior art]

Among expanded polystyrene molded products, the molding process of so-called "moulded products" involves pressing male and female molds with steam chambers, filling the cavities created by the press with pre-expanded particles, and then heating and cooling them. is added, then the mold is opened, and the molded product is then ejected to complete one cycle.

The next step is to dry the ejected molded products and bundle or package each shot. However, molded products produced by modern molding machines equipped with vacuum devices have very little water adhering to their surfaces. Increasingly, the drying process is omitted, and molded products are collected one shot at a time, bundled or packaged, and shipped.

To this end, automatic packing machines and automatic binding machines have been developed that can be used online at molding work sites.

[Problem that the invention seeks to solve]

Now, in the example of a fish box for cold chain distribution of marine products, which is the most in-demand type of styrofoam automatic molding of molded products, the dimensions of the molded product are 300 x soo x
The most common type is ioo w < leprosy, but if you classify it more closely, there are at least several types.

In this way, the dimensions of the molded products vary in length, width, and height, and the molding machines used range from small machines that mold with two-cavity molds to molding machines that can mold about 20 pieces in one shot with two steps. There are various types of molding machines, ranging from large-sized specialized machines, so when one shot of molded products is aligned in the same direction and made into one unit for packaging, the shape of that one unit is as shown in Figure 4. The length of the molded product is horizontal, but the dimensions in this packaging form are approximately W = 500 to 700, H =
330-550 Hou 1, L = 950-1300 Dragon, and the 'C' varies considerably. Moreover, in the stacking direction, there are many stacks of individual molded products with a height of h), and these height h) are 30 tsuru (for dried fish) or 30 tsuru (for fresh fish). Some of the lids are quite thin, such as those whose lids are 1,511 mm taller than the main body. It was often an obstacle to doing so.

Moreover, the automatic packaging cycle takes about 20 seconds, so if a single conveyor were used to feed the next process equipment, the loading worker would have to load the package in a pinch for about 20 seconds. On the other hand, from the perspective of a sorting worker who manually transports molded products from several molding machines to the next process, the work pitch for loading molded products into units onto a conveyor for packaging is , it was unavoidable that the time would vary from 10 seconds to 30 seconds. Therefore, it has become necessary to somehow manage the gap between the uneven loading work pitch and the regular processing pinch of the next process equipment.

The present invention has been made in view of the drawbacks of the conventional example, and it is possible to prevent the molded product from falling at the end during transportation (and to simplify the process between taking out the molded product and the next process of bundling and packing). The purpose is to provide a conveyor for transporting molded products that can be matched and smoothly connect both processes.

[Means for solving problems]

The present invention has been made in view of the drawbacks of the conventional examples. In the molded article conveyance process that connects the molding process and the next process of bundling or packaging, ■ multiple molded articles taken out from the molding process are The molded product transport process is carried out by a loading conveyor (10) that transports the molded products in a stacked manner almost perpendicular to the transport direction, and a feeding conveyor that transports the stacked molded products one unit at a time to the next process. Configure.

■This loading and feeding conveyor (10) (20) -
Set one side lower than the other side.

■Product receiving plates (12) (32) on which the lowest molded product of one unit of stacked molded products slides are arranged along the lower side of the loading and feeding conveyor (10) (20). Set up

■An intermittent motion control panel is installed on the loading conveyor (and), which allows the loading conveyor to move intermittently based on signals from the operator.

A feed conveyor ('m) is provided with a push plate (40) that feeds one unit of molded product to the next process in response to a signal from the zero-order process.

; is adopted as a technical means.

[For production]

Next, the operation of the present invention will be explained.

■First, molded products of various sizes taken out in the molding process are stacked together to form a single unit, and loaded onto the rear end of a loading conveyor.

■Since the loading conveyor (u2) is inclined, the lowermost stacked molded products come into contact with the product receiving plate (12).

■In this state, when the worker sends a signal, the loading conveyor (grain)
moves intermittently to move the molded product forward by one pitch.

■Repeat this action to stack the molded products and load them one unit at a time onto the loading conveyor (rule).

■On the other hand, on the feeding conveyor (concave) side, the loading conveyor (and)
The molded products transferred from the next step are fed one unit at a time to the next process, and in response to a signal from the next process, the push plate (40) reciprocates to feed the molded products in the front row on the feeding conveyor (release). is pushed to the next process.

■According to the above method, in a styrofoam molding factory, each molding machine is producing molded products with different vertical and horizontal dimensions and heights. By stacking molded products for one shot diagonally on the loading conveyor (10), they can be transported to the feeding conveyor (sen) in an orderly manner. By dividing the molded product conveyance process into the loading conveyor (10) and the feeding conveyor (tray), it is possible to match between sorting workers who work at different speeds and the next process, which processes at a constant speed. You can take it.

The conveyor roller (41 (51) has a 7-shaped notch in its center, and a conveyor belt (8) is stretched between both conveyor rollers (4) (5). The conveyor belt (8) is lined with cloth. It is best to use something that is water resistant, such as synthetic rubber.

In addition, in order to prevent the conveyor belt (8) from shifting to the left or right during rotation, a protruding line (7-shaped in cross section) is provided at the center of the inner periphery of the conveyor belt (8).
9) is provided protrudingly, and this protruding line (9) is fitted into the V-shaped notch in the center of the conveyor roller (4) (51).The rear end (B) of the loading conveyor (published) A bracket (11) is erected at right angles to the gantry frame (1) on the left side surface when viewed from the side, and a product receiving plate (12) is fixed to the inner surface of the bracket (11).

The product receiving plate (12) faces the loading conveyor (
That is, the molded product conveyed on the conveyor belt (8) is made of a rust-proof plate material whose inner surface is a sliding surface, and slides on the sliding surface. Of course, a miniature bearing may be incorporated so that the miniature bearing is transferred to the molded product to allow the molded product to move more smoothly. In addition, there is a floodlight (PHS2) near the front end of the loading conveyor (dish).
A photoelectric relay device consisting of a photoreceiver (PHR2) is installed, and the relay in the photoreceiver (PHR2) turns on when the molded product crosses the light beam, and turns off when the molded product passes and the light beam is restored. It acts as follows. There is a control panel (13) near the rear end of the loading conveyor (IJI) that controls the intermittent movement of the loading conveyor (IJI), and the control panel (13) includes a select switch (14) and a counter with settings (15). is provided. (16) is a foot switch that is stepped on by the loading worker, and is used to send a signal from the worker side to cause the loading conveyor (10) to perform intermittent movement. By switching to , the loading conveyor (measurement) can be moved intermittently according to the operator by operating the foot switch (16) via the control panel (13).

Next, the mechanism of the feeding conveyor will be explained with reference to FIGS. 2 and 3. The trestle frame (21) is the trestle frame (11
has the same slope angle. An AC motor (23) with an electromagnetic brake is mounted on a bracket (22) fixed to the rear end of the gantry frame (21). Conveyor roller (

In addition, the air for lifting vertically in the center of the angle material (36)
A cylinder (39) is fixed, and the lower end of the cylinder loft is a push plate that engages with the rear end of the molded product and pushes the molded product forward as the horizontally moving air cylinder (37) moves forward. (40) is fixed horizontally.

Furthermore, as shown in Figure 3, a photoelectric relay device consisting of a light emitter (PHSI) and a light receiver (PHRI) is installed near the front end of the feeding conveyor (total).
) is turned on when the molded part crosses the beam,
It acts to turn off when the molded article passes and the light beam is restored.

The operation of the present invention having the above configuration will be explained below.

First, let me explain the function of the feeding conveyor (Toshi).
If the molded product has been transferred to the front end (A) of the feeding conveyor (dish), the molded product will be transferred to the push plate ( 40
) is sent one unit at a time to the receiving section of the next process equipment. That is, when the motor (23) of the feed conveyor (Ki) rotates and the molded product is transferred to the front end of the feed conveyor (Ki), the light beam of the projector (P)IsI) is temporarily blocked by the molded product. The photorelay of the light receiver (PHRI) is turned on, and when the molded product has passed through the light beam section, the photorelay is turned off and the motor (23) is stopped, entering a standby state.

Under these conditions, when one cycle of the processing work of the packaging machine or packaging machine in the next process is completed, the cycle completion signal will cause the
The lifting air cylinder (39) descends, and at the lowering limit, the horizontal movement air cylinder (37) advances, and the product pressing plate (40) moves forward.
), one unit of the molded product is fed in an obliquely inclined state to a receiving section of the next process equipment which is inclined at the same angle as the feeding conveyor (release) of the present invention. Then, the push plate (40) is stopped by the actuation of a product advance limit sensor (not shown) installed in the next process equipment receiving section, (that is, the horizontal movement air cylinder (37) is stopped, and the lifting air cylinder is (39
) and the return operation of the horizontally moving air cylinder (37), the push plate (40) is raised while being raised, or after being raised, it moves backward and returns to its origin. At the same time, the AC motor (23) starts,
The next molded product is transferred from the loading conveyor (rule) and stops in the above-mentioned waiting state.

As a result of the above action, the feeding conveyor (separate) uses the cycle completion signal from the next process equipment as a tact, and receives IR per tact.
The products are delivered one by one to the next process equipment.

Next, the action of the loading conveyor (■) will be explained.

By the select switch (14) on the control panel (13),
It is possible to switch between two modules: "single" and "linked".

"Independent" is a module that moves in accordance with the work pitch of the product processing worker, regardless of the movement of the feeding conveyor. In other words, a worker who is managing several molding machines collects one shot of molded products every time the mold is opened or ejects a molded product, and stacks them in the same direction to form one unit of molded product. After placing it diagonally on the rear end (B) of the loading conveyor (and), step on the foot swing (16) and turn the AC motor (3).
Activate. At the same time, the counter (15) is activated, and the motor (3) is stopped at a position advanced by the feed stroke set by the counter (15). As a result, a space for approximately one unit of molded product is secured at the 1&end of the feeding conveyor (20) by setting the counter (15).

In the same way, one shot's worth of molded products is placed diagonally in the space secured at the rear end (B) of the feeding conveyor (dish) as one unit, and then the foot switch (16) is depressed.
The loading conveyor (43) is advanced by a stroke. In this way, multiple units of molded products are lined up one after another on the loading conveyor (rule) at predetermined intervals, but the first molded product crosses the beam of light from the projector (PH32), The loading conveyor (10) stops when the photorelay of the light receiver (PHR2) is activated. In this state,
When the next molded product is loaded and the footsinch (16) is stepped on, the counter (15) is reset and if the motor (23) of the feeding conveyor (release) is rotating, the loading conveyor ( The counter (15) is started at the same time as the motor (3) of the cutting conveyor (10) is rotated, and the molded products that were at the front end of the loading conveyor (10) are transferred to the rear end of the feeding conveyor (cutting). When motor (15) performs count amplification, motor (3
) stops.

"Interlocking" is the AC motor (23) of the feeding conveyor (20)
In synchronization with turning on and off, the AC motor (3) of the loading conveyor (■) also turns on and off, and the feeding conveyor (Ki) and the loading conveyor (Saku) move as one module.

〔effect〕

As described above, the present invention provides a loading container that transports a plurality of molded products taken out from a molding process as one unit, overlapping them almost at right angles to the conveyance direction; The molded product conveyance process consists of a feeding conveyor that feeds the next process one by one, and an intermittent motion control panel is installed on the loading conveyor to move the loading conveyor intermittently based on signals from the operator. Since the feeding conveyor is equipped with a push plate that feeds one unit of molded product to the next process,
On the loading conveyor side, the loading conveyor can be driven intermittently according to the work speed of the worker, while on the feeding conveyor side, molded products can be fed according to the next process, even if the work speed is different. It is possible to easily match between the sorting worker side and the bundling process side, which processes molded products at a certain width, and also allows one side of the loading and feeding conveyor to be lower than the other side. A product receiving plate, on which the lowest molded product of one unit of molded products stacked together slides, is arranged along the lower side of the loading and feeding conveyor.
Even if the unit molded products are stacked at different heights, the stacked end molded products will not fall over during transportation, and there is an advantage that reliable transportation can be performed.
